I. Executive Summary
A goal of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP)
is to strengthen collaborative work across disease areas and integrate services that are
provided by state and local programs* for prevention of HIV/AIDS, viral hepatitis, other sexually
transmitted diseases (STDs), and tuberculosis (TB). A major barrier to achieving this goal is the
lack of standardized data security and confidentiality procedures, which has often been cited as
an obstacle for programs seeking to maximize use of data for public health action and provide
integrated and comprehensive services.
Maintaining confidentiality and security of public health data is a priority across all public health
programs. However, policies vary and although disease-specific standards exist for CDC-funded
HIV programs, similarly comprehensive CDC standards are lacking for viral hepatitis, STD, and
TB prevention programs. Successful implementation of common data protections in state
and local health departments with integrated programs suggest implementation of common
data security and confidentiality policies is both reasonable and feasible. These programs have
benefited from enhanced successful collaborations citing increased completeness of key
data elements, collaborative analyses, and gains in program efficiencies as important benefits.
Despite the potential benefits, however, policies have not been consistently implemented
and the absence of common standards is frequently cited as impeding data sharing and
use. Adoption of common practices for securing and protecting data will provide a critical
foundation and be increasingly important for ensuring the appropriate sharing and use of data
as programs begin to modify policies and increasingly use data for public health action.
This document recommends standards for all NCHHSTP programs that, when adopted, will
facilitate the secure collection, storage, and use of data while maintaining confidentiality.
Designed to support the most desirable practices for enabling secure use of surveillance
data for public health action and ensuring implementation of comprehensive evidencebased prevention services, the standards are based on 10 guiding principles that provide the
foundation for the collection, storage, and use of these public health data. They address five
areas: program policies and responsibilities, data collection and use, data sharing and release,
physical security, and electronic data security. Intended for use by state and local health
department disease programs to inform the development of policies and procedures, the
standards are intentionally broad to allow for differences in public health activities and response
across disease programs.
The standards, and the guiding principles from which they are derived, are meant to serve as the
foundation for more detailed policy development by programs and as a basis for determining
if and where improvements are needed. The process includes seven main steps: designating
an overall responsible party; performing a standards-based initial assessment of data security
and confidentiality protections; developing and maintaining written data security policies and
procedures based on assessment findings; developing and implementing training; developing
data-sharing plans or agreements as needed; certification of adherence to standards; and
*State and local is inclusive of state, tribal, local and territorial health departments and agencies.

performing periodic reviews of policies and procedures. NCHHSTP-funded programs will also be
required to verify their adherence to the standards through submission of certification statements.
CDC will work with state and local health departments to monitor the implementation of the
guidelines and evaluate their impact on securing data, facilitating data use, and increasing
program effectiveness.
This document reflects the combined efforts of NCHHSTP’s Surveillance Workgroup members,
composed of surveillance leaders from NCHHSTP’s Division of HIV/AIDS Prevention (DHAP),
Division of Viral Hepatitis (DVH), Division of STD Prevention (DSTDP), and Division of TB Elimination
(DTBE). The work was informed by consultation with state and local public health leaders and
public health organizations representing HIV, viral hepatitis, STD and TB disease disciplines (see
Acknowledgements section). The document supersedes previously published security and
confidentiality guidelines for HIV surveillance and establishes data security and confidentiality
standards for viral hepatitis, STD, and TB. Establishment of these standards that apply to all
surveillance activities in all of the Center’s divisions will facilitate collaboration and service
integration among NCHHSTP-funded programs with minimal risk of inappropriate release of
confidential, identifiable surveillance data or misuse of those data in pursuit of legitimate public
health purposes.

II. Introduction
The true value of surveillance is measured by its impact on public health action and practice.1
Public health agencies at all levels have broad authority to collect, store, and use personal
health information to identify, report, and control health threats and to plan, implement, and
evaluate public health programs and services. The public trusts that any personal or confidential
information collected as part of public health activities will be held securely and confidentially
and will be used for legitimate public health purposes. Although protections exist through various
laws, policies and procedures, these protections vary across jurisdictions2-4 and sometimes even
within public health organizations.5
A goal of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) is
to strengthen collaborative work across disease areas and integrate services that are provided by
programs for prevention of HIV/AIDS, viral hepatitis, other sexually transmitted diseases (STDs), and
tuberculosis (TB).6 A major barrier to achieving this goal is the lack of standardized data security
and confidentiality procedures, which has often been cited as an obstacle for programs seeking to
maximize use of data for public health action and provide integrated and comprehensive services.7
Although disease-specific standards exist for CDC-funded HIV programs,8,9 similarly comprehensive
CDC standards are lacking for viral hepatitis, STD, and TB prevention programs.

2

CDC established data security and confidentiality guidelines for CDC-funded HIV surveillance
programs in state and local* health departments in 19988 and updated the guidelines in 2006.9
The guidelines emphasize the protection of surveillance data and prohibit HIV surveillance
programs from sharing data with programs that lack equivalent data security and confidentiality
protections. These restrictions on data sharing had the unintended consequence of inhibiting
the ability of some local health departments to link clients to appropriate treatment and
prevention services.7,10
In 2008, CDC published updated recommendations for programs providing partner services for
HIV, syphilis, gonorrhea, and chlamydial infections. The document includes recommendations
related to record keeping, data collection, data management, and data security that were based
on previously published HIV surveillance guidelines.11 The partner services recommendations
encourage data linkage and sharing between public health service-provision prevention
programs and disease-reporting surveillance systems. The recommendations suggest that sharing
of individual-level surveillance data can help facilitate the timely provision of partner services but
also underscore the need for well-defined security and confidentiality policies and procedures.
Despite the potential benefits, however, these have not been consistently implemented.
In addition, CDC cooperative agreements with TB programs require that policies and procedures
must be in place to protect the confidentiality of all TB surveillance case reports and files. TB
programs should also collaborate with HIV/AIDS programs to conduct at least annual TB and AIDS
registry matches to ensure completeness of reporting of HIV and TB coinfected patients to both
surveillance systems. However, this collaboration has been hampered by perceived differences in
policies and procedures to protect HIV test results.
This document does not specify details of how, what or when data should be shared but rather
establishes standards of data protection across programs that should be in place. Intended
for use by state and local health department disease programs to inform the development of
policies and procedures, the standards are intentionally broad to allow for necessary differences
in public health activities and response across disease programs. The extent to which data
are used for public health interventions and follow-up with individuals, and to which health
department programs interact or share data with reporting physicians and health providers, will
vary according to established program practices.
This document reflects the combined efforts of NCHHSTP’s Surveillance Workgroup members,
composed of surveillance leaders from NCHHSTP’s Division of HIV/AIDS Prevention (DHAP),
Division of Viral Hepatitis (DVH), Division of STD Prevention (DSTDP), and Division of TB Elimination
(DTBE). The document supersedes previously published guidelines for HIV surveillance and
partner services and establishes up-to-date data security and confidentiality standards of viral
hepatitis, STD, and TB.

*State and local is inclusive of state, tribal, local and territorial health departments and agencies.

Key Definitions Used in this Document
Data sharing: Granting certain individuals
or organizations access to data that contain
personally identifiable information with the
understanding that personally identifiable or
potentially identifiable data cannot be
re-released further unless a special data-sharing
agreement governs the use and re-release of
the data and is agreed upon by the receiving
program and the data provider(s).

Data-sharing agreement: Mechanism by which a
data requestor and data provider can define the terms
of data access that can be granted to requestors.
Data release: Dissemination of data either in a publicuse file or as a result of an ad hoc request which results
in the data steward no longer controlling the use of
the data. Data may be released in a variety of formats
including, but not limited to, tables, microdata (person
records), or online query systems.

Data dissemination: Any mechanism
by which data are made available to users.
Includes mechanisms whereby data are
released to users as well as mechanisms
whereby data are made available without
being released.
Personally identifiable information: As defined by
National Institute of Standards and Technology Special
Publication 800-34, Guide To Protecting The Confidentiality
of Personally Identifiable Information: ”Any information
about an individual maintained by an agency, including (1)
any information that can be used to distinguish or trace an
individual‘s identity, such as name, social security number,
date and place of birth, mother‘s maiden name, or biometric
records; and (2) any other information that is linked or linkable
to an individual, such as medical, educational, financial, and
employment information. “12

III. About this Document
This document recommends standards for data security, confidentiality, and use across surveillance
and program areas for HIV, viral hepatitis, STD, and TB prevention in state and local health jurisdictions.
The standards support the most desirable practices for enabling secure use of data and ensuring
comprehensive preventive services while being broad enough to allow for differences in public
health activities by disease program. The standards address five areas: program policies and
responsibilities, data collection and use, data sharing and release, physical security, and electronic
data security.
The standards are based on 10 guiding principles that provide the foundation for the collection,
storage, and use of surveillance data for public health action. The guiding principles are derived from
existing CDC policies and guidelines, model and existing legislation, and from related work, including
current security and confidentiality principles for NCHHSTP’s HIV surveillance programs and practical
application of ethics in public health surveillance.8,9,11,13-20 Similar principles have been proposed as
part of a national strategy21 consistent with public health values22,23 to ensure the privacy and security
of public health data at all levels.
The standards are intended to apply to public health programs funded by NCHHSTP (including
those of state and local health departments and their contractors) that are responsible for collecting,
storing, and using surveillance data and to any entities with which these programs share data. The
standards address the use of both identifiable (i.e., personally identifiable information [PII]) and
nonidentifiable data and may include: data used for epidemiologic investigations; data used to
link patients with partner services, appropriate treatment, interventions, and other health services;
and data used for case management and program evaluation. Because the use of identifiable data
requires a higher level of protection than the use of nonidentifiable data, the document includes
specific standards for the sharing of identifiable data. Key definitions for data sharing, data release,
data release agreement, data dissemination, and personally identifiable information are highlighted in
the box above and additional terms are provided in the Glossary (Appendix A).

IV. Using this Document
Active data stewardship involves developing proactive policies, procedures, and training to ensure
that public health data are collected, stored, and used appropriately. To that end, policies related
to the security and sharing of data should be reviewed regularly and changed as needed. The
data standards and the guiding principles from which they are derived are meant to serve as the
foundation for more detailed policy development by programs and as a basis for determining if and
where improvements are needed. Key components of data security and confidentiality, sharing, and
use policy development are outlined below.
Overall Responsible Party (ORP)—A high-ranking official should be identified to accept overall
responsibility for implementing and enforcing data security, confidentiality and sharing standards.
This official should have the authority to make decisions about program operations that might affect
programs authorizing, accessing or using the data, and should serve as the contact for public health
professionals regarding security and confidentiality policies and practices. If the required span of
control is not under a single person’s purview, several persons can serve in the capacity of ORP as an
ORP panel.
5

Initial Assessment of Data Security and Confidentiality Protections—This document is
intended to serve as a planning resource for use by state and local public health programs to
develop or upgrade their data security and confidentiality policies and procedures. An initial
assessment will be particularly useful for state and local public health programs that currently lack
data security and confidentiality policies and procedures.
A team led by the ORP should conduct an initial assessment of current data security
and confidentiality protections. The team should include:
ƒƒ Program managers, directors, or equivalent leaders from participating programs
ƒƒ Other representatives of participating programs who may provide insight on access
requirements and procedures for certain jobs or duties (e.g., surveillance staff, DIS data
managers)
ƒƒ Staff members with technical expertise in data security
Information technology (IT) staff should be involved at an early stage to ensure that they
understand the data security and confidentiality standards and are fully engaged in the overall
process. This involvement is critical as areas move to more centralized IT services and, in some
cases, outsourced IT services.
The initial assessment should include the following steps:
ƒƒ Identify key individuals and designate an ORP or ORP panel
ƒƒ Review current security and confidentiality-related materials (e.g., written policies,
procedures)
ƒƒ Review relevant state and local laws that might affect data security and
confidentiality policies
ƒƒ Identify any policies or procedures that are either sources of data security weaknesses or
barriers to information sharing and consult standard operating procedures (SOPs) from
other programs that might be useful sources of ideas or suggestions for procedural changes
ƒƒ Review any history of data security breaches or near-breaches, and associated
lessons learned
ƒƒ Assess physical security and define the secure area
ƒƒ Assess electronic security protections and methods of electronic data transfer and storage
ƒƒ Assess factors related to security of information in the field
ƒƒ Assess training needs
Sample checklists for conducting initial and comprehensive assessments are provided in Appendix B.

6

Data Security and Confidentiality Policies and Procedures—Programs required by NCHHSTP
to meet these guidelines are responsible for developing and maintaining written, program-specific
data security and confidentiality policies and standard operating procedures, based on these
guidelines, the assessment findings and in the context of state and local laws. Legislative and
regulatory barriers to these standards should be addressed. State health department programs
should work collaboratively with local health departments and public health partners involved
in surveillance and prevention-related activities to maintain equivalent standards to the extent
possible. State programs that subcontract directly with local health department programs
may include compliance with these guidelines in their contractual arrangements. Local health
departments that share data with state health departments should share data using the secure
methods outlined in this document. NCHHSTP-funded programs may provide assistance to private
providers and laboratories in implementing secure methods for reporting case data. Providers and
laboratories should be encouraged to establish policies and procedures and regular training on
data security and confidentiality, according to these standards.
When public health data are collected or used as part of federally funded research, they are also
subject to the federal policy for the protection of human subjects as described in the Code of
Federal Regulations, Title 45, Part 46.24
Training—Staff members authorized to access and use public health data are responsible for
adhering to their programs’ data security and confidentiality policies and procedures and should
receive ongoing training on an annual basis on the appropriate collection, storage, use, and
dissemination of data as defined by these policies.
Data-Sharing Plans—Shared data facilitates identification of populations at risk for multiple
infections and the design and implementation of programs that comprehensively address
identified needs. A written plan can serve as a starting point for discussions about data sharing
between or among public health programs. A data-sharing plan should include:
ƒƒ Intent and scope of data sharing
ƒƒ Potential benefits (including projected efficiencies) and risks of sharing, benefits and risks of
not sharing, and methods to monitor these benefits and risks
ƒƒ Methods that will be used to share data and roles and responsibilities of staff involved
ƒƒ Minimum data elements needed to achieve the objective(s), including need for PII
ƒƒ Steps that will be taken to ensure the confidentiality and security of shared data
ƒƒ Provisions for physical and electronic security
ƒƒ How shared data will be used, analyzed, published, released, and retained/destroyed
ƒƒ Confidentiality agreements
ƒƒ Knowledge and training requirements including annual training for staff who have access to
PII and non-PII data

7

Although a written plan might not seem necessary between programs in the same health
department or in integrated programs, having a plan in writing can help in resolving any conflicts.
A more formal agreement, such as a data-sharing agreement or Memorandum of Understanding
(MOU) may be required in certain circumstances (e.g., sharing outside the health department or
with another public health organization). Programs can consult legal experts in their organizations
to determine the need for a formal agreement.
Appendix C includes an example of one method of data sharing to improve program efficiencies
and effectiveness.
Certification—Programs are required to self-certify their adherence to the standards for ensuring
the security, confidentiality, and appropriate use of the data they collect, store, and share. The
certification statement should:
ƒƒ Identify one or more persons as the ORP for ensuring adherence to the standards
ƒƒ Attest to adherence to all standards, or explain any lapses
ƒƒ If lapses, describe steps to meet the standards in the future
ƒƒ Describe policies and procedures instituted to ensure continued adherence to the
standards
NCHHSTP will describe the certification process in applicable program announcements. NCHHSTP
will conduct periodic reviews of the data security, confidentiality and sharing procedures of grant
recipients during routine site visits and provide technical assistance as needed.
A suggested format for a certification statement is provided in Appendix D.
Periodic and Ongoing Reviews and Assessments—Programs should review their data
security, confidentiality, and sharing policies and procedures at least annually or sooner if
improved technologies or legislative/regulatory changes occur and revise as necessary. In
addition, they should periodically assess whether other changes in personnel, programs,
organizations, or priorities require changes in policies and procedures. For example, changes
in federal standards for encryption could affect existing policies and procedures and require
software updates or other revisions.
Programs should also review their data-sharing plans or agreements periodically in light of
improved technologies and revise as necessary. Tracking the security and confidentiality training
of staff members authorized to access data, including documenting and storing their signed
confidentiality agreements, should also be part of ongoing assessment activities.

V. Benefits, Risks, and Costs of Sharing Data and
Maintaining Security and Confidentiality
There is a balance that must be maintained between protecting the individual and the public from
disease and protecting individuals’ confidentiality and right to privacy. Both are vital to enhancing
the public’s health and maintaining the public’s trust. Programs that have and follow consistent
guidelines for the collection, storage, and use of HIV, viral hepatitis, STD, and TB data may reassure
individuals, and the public, that sharing data for public health action will not compromise
confidentiality.
Adherence to harmonized standards for data security across programs will enhance the ability
to share data without compromising confidentiality. As programs consider how best to meet
these standards, it is helpful to consider the benefits, risks, and costs. The public health benefits of
sharing data among HIV, viral hepatitis, STD, and TB programs include the following:
ƒƒ Early case detection and accurate and timely reporting of diseases
ƒƒ Improved efficiencies in use of human and financial resources to achieve program
objectives
ƒƒ Improved projections of human and financial resources for disease programs and
specific projects
ƒƒ Improved opportunities to inform providers and patients about standards of care and
needs for additional care
ƒƒ Enhanced quality of surveillance data across programs
ƒƒ Improved documentation and reporting of co-morbidities, leading to better patient
management and partner services
ƒƒ Better understanding of patients’ health status to ensure comprehensive care and avoid
redundant services and missed opportunities for prevention
ƒƒ Increased understanding of how epidemics interact synergistically (syndemics),
geographically, within population subgroups, or within groups engaging in specified
high-risk behaviors
ƒƒ Identification of specific populations that need outreach with consistent messages
and targeted testing and service provision

9

Although data sharing has many benefits, there are also some risks. Despite the public health
community’s excellent track record in managing sensitive data, security breaches can occur.
Harmonized data security and confidentiality standards among programs, and a commitment
to enforcing them, can, however, minimize these risks. Breaches involving electronic data with
identifiable information (e.g., human error resulting in reports going to the wrong patient or
provider or databases being stolen or accessed illegally) might cause greater harm because more
information about more individuals is released. Therefore, procedures for electronic data security
must be developed. However, there are also some risks to not sharing data. Individuals might not
receive prevention services, clients might not receive appropriate treatment, clients might not
receive treatment at all, and disease transmission might increase.
Costs associated with improvements in data security can be a barrier to data sharing. To
facilitate data sharing, hardware and software systems need to be compatible. Electronic
transfer of data needs to be performed securely. Storage of data needs to be secure and
remain confidential at all levels. Additional computer programming support may be required
to facilitate secure data sharing across programs, conduct data matches, meet systems
requirements, and de-duplicate data.

VI. Guiding Principles for Data Collection, Storage, Sharing,
and Use to Ensure Security and Confidentiality
The 10 principles below are intended to guide NCHHSTP-funded programs in developing data
security and confidentiality policies. The principles should guide the collection, storage, and use of
data for legitimate public health purposes. Legitimate public health purposes can be defined as a
population-based activity or individual effort aimed primarily at the prevention of injury, disease, or
premature mortality. This term also refers to the promotion of health in the community, including
1) assessing the health needs and status of the community through public health surveillance and
epidemiologic research; 2) developing public health policy; and 3) responding to public health
needs and emergencies. Public health purposes can include analysis and evaluation of conditions
of public health importance and evaluation of public health programs. The principles also
underpin the data security standards defined in the following section.

Programs should collect the minimum amount of personally
identifiable information necessary to conduct public health activities.
Programs should have strong policies to protect the privacy and
security of personally identifiable data.
Data collection and use policies should reflect respect for the rights
of individuals and community groups and minimize undue burden.
Programs should have policies and procedures to ensure the quality
of any data they collect or use.
Programs have the obligation to use and disseminate summary data
to relevant stakeholders in a timely manner.
Programs should share data for legitimate public health purposes
and may establish data-use agreements to facilitate sharing data in a
timely manner.
Public health data should be maintained in a secure environment
and transmitted through secure methods.
Minimize the number of persons and entities granted access to
identifiable data.
Program officials should be active, responsible stewards of public
health data.

VII. Standards for Data Collection, Storage, Sharing, and
Use to Ensure Security and Confidentiality
The following standards are based on the 10 guiding principles listed in the previous section.
They represent recommended standards to ensure the security, confidentiality, and appropriate
use, including sharing, of data collected by NCHHSTP-funded programs.
The standards are grouped into five topical areas: program policies and responsibilities; data
collection and use; data sharing and release; physical security; and electronic data security. Each
standard is followed by a brief background or explanatory statement and a set of questions to
guide programs in policy development and implementation.

1.0  PROGRAM POLICIES AND RESPONSIBILITIES
STANDARD 1.1  Develop written policies and procedures on data security and
confidentiality; review policies and procedures at least annually; revise them as
needed; and ensure their review by and accessibility to all staff members having
authorized access to confidential individual-level data.
Programs should develop and maintain written policies and procedures on data security and
confidentiality. Written policies and procedures should include:
ƒƒ Review of applicable laws and regulations
ƒƒ Description of applicable data (include details on types of records, systems, and reports)
ƒƒ Roles and responsibilities of persons with authorized access to the data
ƒƒ Applicable confidentiality agreements
ƒƒ Controls for data management, security, and access (physical and electronic)
ƒƒ Address when use of privacy advice or reminder is appropriate (i.e., when to include
privacy advice at the point of information use on forms, information collection
devices, systems, file cabinets, etc.)
ƒƒ Specified policies applicable to trainees, students, volunteers, visitors, and cleaning
and security staff.
ƒƒ Provisions to limit disclosure and prevent indirect release of PII
ƒƒ Guidance on data sharing
Policies should be introduced to new staff members, students, and volunteers during orientation
and reviewed with all staff members during annual training sessions. Staff members should also
be notified of any changes or updates to data security policies.
See Appendix E for a suggested outline of a policy for data security, confidentiality, sharing and use.

GUIDING QUESTIONS:
»» Does the program have written policies and procedures on data security
and confidentiality?
»» Are the policies and procedures consistent with the standards in this document?
»» Are the policies and procedures available and accessible to program staff?
»» Are staff trained in the policies and procedures and alerted to any revisions?

STANDARD 1.2 Designate a person or persons to act as the overall responsible party
(ORP) for the security of public health data your program collects or maintains, and
ensure that the ORP is named in any policy documents related to data security.
The purpose of naming an ORP is to increase program accountability for data security. The
ORP should have the authority to modify programs and policies to meet the standards in this
document. The ORP can be selected from the program, section, or agency level. The agency’s
organizational structure might demand designating more than one person as ORP (i.e., an ORP
panel). The ORP(s) may also choose to have data releases or proposed data sharing activities
reviewed by a group of designated individuals to facilitate the review process and ensure the risks
and benefits of the proposed activities are considered and make recommendations.

»» Has an ORP been designated and named in all relevant policy documents?
»» Does the ORP have authority to modify data security policies and prodedures for compliance
with the standards in this document?

STANDARD 1.3  Ensure that data security policies define the roles and access levels
of all persons with authorized access to confidential public health data and the
procedures for accessing data securely.
Access to surveillance data needs to be planned. The number of people with access to identifiable
information should be kept to a minimum, and de-identified data should be used for routine
analyses whenever possible. Operational security procedures should be devised to minimize the
number of people with access to confidential data. Written procedures should specify how to obtain
authorization for access to both PII and de-identified data.
GUIDING QUESTIONS:
»» Is authorized access granted based on the data user’s need to know?
»» Is the number of persons with access to PII kept to a minimum?

13

STANDARD 1.4  Ensure that data security policies require ongoing reviews of
evolving technologies and include a computer back-up or disaster recovery plan.
Because the technology used to secure data is constantly evolving, information technology and
security professionals should be included in the development and review of data security policies
and procedures. Policies should include plans for a secondary, secure, off-site computer operation
that can go into effect in the event of a catastrophic failure at the primary location. The National
Institute of Standards and Technology Special Publication 800-34, Contingency Planning Guide for
Federal Information Systems contains guidance on contingency planning for IT resources and is
available at: http://csrc.nist.gov/publications/PubsSPs.html. 25
GUIDING QUESTIONS:
»» Have persons with technical expertise in information and system security been consulted to
ensure that data security policies and procedures are adequate?
»» Do policies and procedures include a disaster recovery plan?

STANDARD 1.5  Ensure that any breach of data security protocol, regardless
of whether personal information was released, is reported to the ORP and
investigated immediately. Any breach that results in the release of PII to
unauthorized persons should be reported to the ORP, to CDC, and, if warranted to
law enforcement agencies.
Guidelines for a risk-based approach for protecting confidentiality of PII, including responding
to breaches (incident response), are described in the National Institute of Standards and
Technology Special Publication 800-122, Guide to Protecting the Confidentiality of Personally
Identifiable Information available at http://csrc.nist.gov/publications/. 12 The data security
policy should include procedures for reporting suspected breaches, including who to notify
about a suspected breach. Staff members should be familiar with the program’s definition of a
security breach. Staff members should review procedures during annual security training. A log
of security breaches and lessons learned during investigations of breaches might be useful in
revising security policies.
Breaches that do not result in the release of PII can be handled within programs. Breaches that
result in unauthorized disclosure of PII require immediate consultation with legal counsel and
notification of high-level authorities in the agency to ensure appropriate action. There are federal
requirements for reporting breaches of PII involving federal data or federal supported systems.
For instance, based on OMB Memorandum 06-19 (http://www.whitehouse.gov/sites/default/
files/omb/memoranda/fy2006/m06-19.pdf ),26 if PII from a federally supported system were to be
released to, or stolen by, unauthorized persons, that breach must be reported to federal security
officials within one hour of its discovery. For NCHHSTP, the designated person is the Information
System Security Officer (ISSO) for the Center. Both the ISSO and the CDC program contact need to
be notified immediately.

14

GUIDING QUESTIONS:
»» Are procedures in place to respond to breaches in data security?
»» Does the data security policy identify the person to be notified if a breach is suspected?
»» Are staff members familiar with the program’s definition of a security breach?

STANDARD 1.6  Ensure that staff members with access to identifiable public health
data attend data security and confidentiality training annually.
All staff members (including IT personnel, contractors, and mail room and custodial staff ) require
generic security awareness training to ensure and support a culture of confidentiality, but staff who
have access to PII require additional training specific to their responsibilities and level of authorized
access to PII. Training should cover:
ƒƒ Personal responsibilities
ƒƒ Procedures for ensuring physical security of PII
ƒƒ Procedures for electronically storing and transferring data
ƒƒ Policies and procedures for data sharing
ƒƒ Procedures for reporting and responding to security breaches
ƒƒ Review of relevant laws and regulations
All staff should have documentation of completion of their training. Programs are responsible for
maintaining this documentation in their personnel files.
GUIDING QUESTIONS:
»» Is security training required for new staff members and annually for all staff members?
»» Are there specific modules related to job responsibilities? For example, mail room and
custodial staff would have different training components based on job duties and likelihood
of access to confidential material.
»» Does the training cover the standards in this document?
»» Does the training include a review of physical and electronic data security procedures,
confidentiality procedures, and release and sharing procedures on an ongoing basis?
»» Is attendance at the training sessions documented?
»» Are training materials updated as needed?

15

STANDARD 1.7  Require all newly hired staff members to sign a confidentiality
agreement before being given access to identifiable information; require all staff
members to re-sign their confidentiality agreements annually.
All staff (including IT, mail room, and custodial staff ) should sign a nondisclosure or confidentiality
agreement stating that the employee agrees not to release PII to any unauthorized persons. The
agreement should be maintained in the employee’s personnel file. A confidentiality agreement
should be required before assigning passwords or keys that allow access to PII. Policies and
procedures should address staff out-processing and relinquishment of authorized access.
GUIDING QUESTION:
»» Are all staff members required to sign a confidentiality agreement before they are granted
access to PII?

STANDARD 1.8  Ensure that all persons who have authorized access to confidential
public health data take responsibility for 1) implementing the program’s data
security policies and procedures, 2) protecting the security of any device in their
possession on which PII are stored, and 3) reporting suspected security breaches.
The data security responsibilities of staff members should be incorporated into their confidentiality
agreements and reviewed during annual training. Supervisors should consider including
security-related questions in annual performance reviews as a way of gauging staff members’
understanding of their data security responsibilities.
Responsibilities of persons with authorized access to PII include but are not limited to:
ƒƒ Protecting keys, passwords, and codes that would facilitate unauthorized access to PII
ƒƒ Taking appropriate action to avoid infecting computer systems with viruses
and other malware
ƒƒ Protecting computers and devices from extreme heat and cold
ƒƒ Protecting mobile devices and storage media from loss or theft
ƒƒ Appropriate use of personal computers and storage devices
ƒƒ Appropriate removal of data from secure facilities
GUIDING QUESTIONS:
»» Are the data security responsibilities of staff members outlined in their confidentiality agreements?
»» Are these responsibilities reviewed annually?
»» Are staff members aware of relevant data security policies? Have they completed
security training?
»» Do staff members know how, and to whom, to report suspected security breaches or instances of
unauthorized access? Are they familiar with the criteria for reporting and investigation?

16

STANDARD 1.9  Certify annually that all data security standards have been met.
Programs should self-certify annually and work collaboratively with CDC to address any problem
areas. At a minimum, programs should provide a statement that:
ƒƒ Identifies the ORP
ƒƒ Attests to the program’s adherence to the data security standards
ƒƒ Cites policies and procedures that document adherence to these standards
ƒƒ Documents any reasons for non-adherence, with plans for remediation
GUIDING QUESTIONS:
»» Has an ORP been named?
»» Has a statement attesting to adherence to the standards been provided?
»» Is a list of confidentiality and security policies and procedures available upon request?

2.0  DATA COLLECTION AND USE
STANDARD 2.1  Clearly specify the purpose for which the data will be collected.
Written policies and procedures should describe the intended public health purposes for
collecting data and the scope and limits of the data collection activities when data are shared or
used. A “legitimate” public health purpose includes efforts to prevent disease or premature death or
promote health among members of a community through activities such as:
ƒƒ Assessing the health needs and health status of a community through public health
surveillance and epidemiologic research
ƒƒ Developing public health policy
ƒƒ Responding to public health needs and emergencies
ƒƒ Evaluating public health programs
GUIDING QUESTIONS:
»» What is the rationale for the proposed data collection?
»» What is the intended use for the data?
»» What are the limits on how the data may be used?
»» Is the proposed data collection likely to lead to a reduction in morbidity and mortality rates
through targeting of public health interventions without creating undue burdens?
»» Is the proposed data collection significantly different from other approved public health data
collection efforts?

17

STANDARD 2.2  Collect and use the minimum information needed to conduct
specified public health activities and achieve the stated public health purpose.
Before implementing data-collection or data-sharing activities, public health practitioners should
specify minimum data elements and consider whether collection and use of personally identifiable
data will be necessary to achieve their public health goal.
The minimum information requirement will vary based on the activity. For example, certain
personal identifiers are required for activities requiring follow-up with individuals; for partner
services, that might include name and locating information such as an address, in addition to
other information deemed critical for the investigation. When considering a new data-collection
or data-sharing effort, consider the following guidelines:
ƒƒ Specify minimum data elements, and include only the information needed to achieve the
public health goal(s).
ƒƒ Minimize or avoid collecting information just because it might be of later use or because
it is easily accessible.
ƒƒ Refer to similar high-quality data-collection efforts or data-sharing activities with
proven success.
ƒƒ Avoid unnecessary retention or creation of multiple data collections or data management
systems (the more collections/systems, the greater the complexity of security management).
GUIDING QUESTIONS:
»» What is the minimum amount of demographic, geographic, and health-related data needed to
accomplish the public health goal of the proposed data collection?
»» Are all proposed data elements justifiable in terms of their contribution toward achieving the
public health goal?
»» Are key data elements similar enough to those collected through previous data collection
efforts to allow needed comparisons?

STANDARD 2.3  Collect personally identifiable data only when necessary; use
nonidentifiable data whenever possible.
Identifiable data require a higher standard of protection than nonidentifiable data. Collection
and use of identifiable data are justifiable if the data are to be used for a public health purpose
that cannot be achieved through the use of nonidentifiable data. Published standards and
recommended practices for maintaining confidentiality of PII and de-identification of data can be
used to guide policy development. 12, 18, 27-32

18

GUIDING QUESTIONS:
»» Is the use of PII necessary to achieve the public health goal of the proposed data collection?
»» Have possible alternatives to using identifiable data, such as using anonymized data,
been explored?
»» What are the risks and benefits of using identifiable data?
»» What is the scientific reliability and validity of identifiable data when used for the
purposes proposed?
»» When should informed consent be obtained, and what should be done when obtaining
informed consent is not feasible?
»» Can identifying information be separated from other sensitive information by the use
of a meaningless common identifier?

STANDARD 2.4  Ensure that data that are collected and/or used for public health
research are done in accordance with stipulations in Common Rule, Title 45, Part
46 of the Code of Federal Regulations, which includes obtaining both institutional
review board (IRB) approval for any proposed federally funded research and
informed consent of individuals directly contacted for further participation.
The use of identifiable data for research is contingent on a demonstrated need for the data,
IRB approval, and the signing of a confidentiality agreement regarding rules of access and final
disposition of the information. The use of nonidentifiable data for research is generally permissible
but might still require IRB approval, depending on the amount and type of data requested.
Programs should consult applicable guidance on research versus practice and human subjects
regulations.24,33
GUIDING QUESTIONS:
»» What procedures are in place to determine whether a proposed use of identifiable public health
data constitutes research requiring IRB review?
»» Has the proposed research been determined to serve a legitimate public health purpose?
»» Has the proposed research been submitted for appropriate review and evaluation
by an IRB?
»» What efforts have been made to inform the public or affected communities about research
involving identifiable data?

19

3.0  DATA SHARING AND RELEASE
STANDARD 3.1  Limit sharing of confidential or identifiable information to those
with a justifiable public health need; ensure that any data-sharing restrictions do not
compromise or impede public health program or disease surveillance activities and
that the ORP or other appropriate official has approved this access.
This standard applies to the sharing of data with other public health entities that might need
routine access to the data for a related public health function. For example, a TB surveillance unit
and HIV unit that routinely match case registries to update case information might require some
reciprocal access to each other’s information. Or, a partner services program might need access to
limited information on newly reported HIV cases to initiate partner services. Such access should
be authorized by the ORP(s) of the program(s) maintaining the data and limited to the minimum
number of persons, and amount of information necessary.
When proposing changes to policies affecting access to public health data, if the changes are
significantly different from standard practices or controversial, it is good practice to first seek input
from members of affected communities, medical providers, and/or other key stakeholders to ensure
that the proposed changes do not adversely affect public trust in, or the integrity of, the public
health system.
For any routine, authorized sharing of information, programs should verify:
ƒƒ Appropriateness of sharing
ƒƒ Integrity of the information shared
ƒƒ Identity of the recipient
ƒƒ Security of the method through which the information will be shared
GUIDING QUESTIONS:
»» Is access to PII necessary to achieve a specified public health function?
»» Have steps been taken to limit access to the fewest number of persons necessary?
»» Is information sharing reduced to the minimum information necessary?
»» Do procedures by which data will be accessed include adequate data security and
confidentiality protections?

STANDARD 3.2  Assess the risks and benefits of sharing identifiable data for other
than their originally stated purpose or for purposes not covered by existing policies.
Public health interventions and research often rely on the use of shared data. However, strict norms
of privacy and confidentiality must govern any sharing of data, and de-identified data should be
used whenever possible. Data should be shared only for legitimate public health purposes and all
data sharing must comply with applicable laws and regulations. See Glossary in Appendix A for a
definition of legitimate public health purposes.
20

Determining whether proposed data sharing is “legitimate” often involves ethical questions. An
autonomous body composed of persons familiar with ethics in public health surveillance may
provide insight and feedback on proposed activities.34 Several models of ethical decision-making
might provide useful, practical guidance for decisions on data use.35-39
ƒƒ Begin by identifying the public health ethics issues in the specific situation, including those
related to risks and benefits, public health goals, stakeholders, and precedent cases.
ƒƒ Generate and compare different options or courses of action and the ethical rationale for
each. Choose the best option and justify the chosen course of action.
ƒƒ Evaluate the selected action to determine if the desired outcome was achieved.
GUIDING QUESTIONS:
»» Have all alternatives to sharing such data been explored?
»» Is the sharing of identifiable data necessary?
»» Is the proposed use within the scope of your data-release policy and for a legitimate public
health purpose?
»» Have the security and confidentiality standards of the requesting party been assessed? Are
the standards adequate?
»» Does the entity receiving identifiable data have in place confidentiality and security standards
that meet the standards outlined in this document?

STANDARD 3.3  Ensure that any public health program with which personally
identifiable public health data are shared has data security standards equivalent to
those in this document.
Confidentiality can be compromised if data are shared with programs that lack adequate security
and confidentiality protections.
ƒƒ Share data only after the ORP(s) has weighed the benefits and risks of allowing access.
ƒƒ Share data only with programs that have written policies and procedures establishing data
security and confidentiality protections equivalent to those in this document.
GUIDING QUESTIONS:
»» Does the program accessing the data have written security and confidentiality policies and
procedures?
»» Have the policies and procedures been reviewed and found to be consistent with the
standards in this document?

21

STANDARD 3.4  Ensure that public health information is released only for purposes
related to public health, except where required by law.
Programs should establish data release policies and procedures that delineate any exceptional
circumstances that may warrant the release of identifiable data and how the confidentiality of
such data will be protected. Programs can develop routine disclosure procedures that outline a
process for reviewing routine disclosures.40 Review procedures could include designating a group
of persons, including the ORP(s) to review nonroutine data releases. Before allowing nonroutine
disclosures, policies could include a brief period of contemplation, or timeout, before releasing
data to minimize risk of improper disclosure.40
Programs should not release PII to anyone outside of public health except in circumstances
involving significant risk of harm to the public or if required by law. Even when required, only the
minimum information should be released. The ORP and legal counsel of the program(s) controlling
the data should review any request for PII to determine the specific data, if any, that must be
released. In some instances, the information requested may be available from other sources. When
information is ordered for release as part of a judicial proceeding, any release or discussion of
information should occur in closed judicial proceedings, if possible.
GUIDING QUESTIONS:
»» Is the release of identifiable data to officials in law enforcement, immigration control, or public
welfare management justified by an imminent threat to individuals or populations or other
compelling circumstances?
»» Have all possible alternatives to the use of identifiable data been examined before the release
of such data?
»» Has a legal analysis been conducted by the health department’s legal counsel?
»» What non-public health use of the data is required or allowed by law?

STANDARD 3.5  Establish procedures, including assessment of risks and benefits,
for determining whether to grant requests for aggregate data not covered by
existing data-release policies.
Procedures could include a process designating a group of persons to review requests that are
outside the stated policy. Any data release must be for a legitimate public health purpose and in
accordance with applicable laws and regulations.
GUIDING QUESTION:
»» Are there precedents for the requested release of data? If so, how were those
precedent cases handled?

22

STANDARD 3.6  Disseminate nonidentifiable summary data to stakeholders as
soon as possible after data are collected.
Written policies should address procedures for the dissemination of nonidentifiable summary data
to stakeholders and the public. Summary data should be disseminated in a manner that facilitates
understanding by affected populations and illuminates the compounding impact of syndemics.
Since some aggregate data could be used to identify individuals, policies should usually restrict
release of certain data elements to avoid a confidentiality breach. Wider public access and
searchability of databases (e.g., death records and obituaries) increases the capability to re-identify
other de-identified data. Consideration should be given to consulting with de-identification
experts prior to release when in doubt. In some instances, the obligation to use the data to
help members of demographic groups examine trends and burden of disease for public health
planning might outweigh the risk of possible stigma that could be associated with some
aggregate data. For example, the release of data showing high rates of alcohol and drug use in
a small community, although potentially stigmatizing, must be weighed against the potential
additional resource planning and allocation for drug and alcohol treatment services that could
result from such a release.
GUIDING QUESTIONS:
»» Have data dissemination plans been described? What efforts have been made to ensure that
nonidentifiable data are disseminated regularly and in a timely manner?
»» Are procedures in place to assess the usefulness of data dissemination efforts?
»» What precautions have been taken to ensure that the disseminated data are not presented in
ways that may indirectly identify individuals?

STANDARD 3.7  Assess data quality before disseminating data.
Evaluations of data quality should occur during collection, management, analysis, and use to
ensure sufficiently accurate and valid data. The quality of public health data is critical to the validity
of public health policies and actions based on these data.
Guidance on ensuring data quality is provided in the HHS Guidelines for Ensuring the Quality of
Information Disseminated to the Public, Part D, CDC and the Agency for Toxic Substances and
Disease Registry (ATSDR). Quality assurance mechanisms described in the document include
internal reviews, external reviews, merit reviews, and peer reviews. Programs may also consult
with independent researchers and experts in areas such as data collection and data analysis;
maintain ongoing contact with data users and participate in conferences and workshops to assess
the needs of potential data users; and use a wide variety of dissemination mechanisms to make
statistical and analytic information broadly accessible.41

23

STANDARD 3.8  Ensure that data-release policies define purposes for which the data
can be used and provisions to prevent public access to raw data or data tables that
could contain indirectly identifying information.
The main challenge in developing responsible data-release policies is to balance the need to make
data available to a broad audience and in a timely manner with the need to protect individual
privacy. Data-release policies should address:
ƒƒ Purpose and types of data (e.g., de-identified, patient-level, and aggregate) that can be released
ƒƒ Intended audience
ƒƒ Rules for suppression
ƒƒ Rules for dissemination of aggregate data products
ƒƒ Physical and electronic (including IT) controls to ensure data security
ƒƒ Mechanisms and procedures for requesting data and considering data requests
ƒƒ Suggested formats for data-use agreements
Useful standards for data-release and data-sharing reflect principles and policies outlined in the
CDC/ATSDR Policy on Releasing and Sharing Data,13 the CDC-CSTE Intergovernmental Data Release
Guidelines Working Group Report: CDC/ATSDR Data Release Guidelines and Procedures for Rerelease of State-Provided Data.4 The CDC/ATSDR policy provides guidance aimed at balancing the
desire to disseminate data as broadly as possible with the need to maintain high standards and
protect confidential information, while also ensuring compliance with applicable federal regulations
and guidelines. The Office of Management and Budget’s (OMB) Federal Committee on Statistical
Methodology, Statistical Policy Working Paper 22: Report on Statistical Disclosure Limitation
Methodology also provides useful guidance for developing data release policies.31
GUIDING QUESTIONS:
»» Do the data-release policies address the following?
• Roles and responsibilities of program personnel, including any confidentiality
  agreements they must sign and any training they must receive
• Access procedures and authorization rules
• Descriptions of the data and to whom, and in what format, they can be released
• Procedures for data release
• Specific requirements for sharing identifiable data
• Mechanisms for data release, including rules for minimizing disclosure such
as cell-size restrictions
• Disposition of data after they have been used for a stated purpose
»» Do data release plans include mechanisms for evaluating the usefulness of released data
and whether the release of data is causing undue burden on individuals or communities?

24

4.0  PHYSICAL SECURITY
STANDARD 4.1  To the extent possible, ensure that persons working with hard copies
of documents containing confidential, identifiable information do so in a secure,
locked area.
Physical access controls should be in place to protect hard-copy data and computer equipment.
Operational security procedures should be devised to minimize the number of storage locations in
which PII is held.
Minimum Secure Area
ƒƒ Work space with limited access for only necessary staff
ƒƒ Locked file cabinets that are large and heavy enough to render them immobile
ƒƒ A designated location within the work space where confidential conversations may be held
Enhanced Security Configurations
ƒƒ A dedicated, secure area accessible only via locked door with limited key or keycard
distribution to minimal staff
ƒƒ Double-locked file cabinets that are large and heavy enough to render them immobile
ƒƒ A workstation/table equipped with a telephone and computer to handle data within
the secure space
A dedicated, secure room would be the preferred location for confidential, secured data stored in
locked, immobile cabinets. Additionally, this space could provide a table or work station for staff
to conduct confidential telephone conversations. In the absence of a dedicated, secure room, a
reasonable alternative could be an area which is accessible only from within the surveillance area to
house immobile, locked file cabinets. If necessary, one secure file cabinet could be shared by several
small programs within a jurisdiction if they have the same data security standards.
If data must be stored or used in less than ideally secure work areas, the security of these areas should
be improved as much as possible. For example, in many workplaces confidentiality is improved
by requiring paper documents with confidential information to be kept locked in desk drawers
when not in use or when a worker is away from his or her desk. Security might also be improved by
reconfiguring cubicles, office partitions, and requiring confidential phone conversations to take place
in a private room. This is not an exhaustive list of improvements, but it shows that creative thinking
may be needed to turn an open work area into a more secure workplace.
In the course of public health work, and in the evolving modern work environment, confidential
data may be handled not only outside the secure work area, but off-site, in the field, or in telework/
remote sites (see Appendix G for guidelines on working in nontraditional settings).

25

It is critical that project areas develop and implement protocols for telework, remote work, and field
work, in addition to core confidentiality and security policies. Even if these work activities have not
yet been implemented in a project area, provisions should be made for their future implementation
by including them in the current protocols.
GUIDING QUESTIONS:
»» Are hard copies of confidential or identifiable data kept in a secure area?
»» Are physical controls adequate to ensure that paper copies of material containing identifiable
data are secured in lockable filing cabinets within a locked secured area with controlled access?

STANDARD 4.2  Ensure that documents containing confidential information are
shredded with crosscutting shredders before disposal.
Crosscutting features are needed to ensure confidential information cannot be recovered.
See National Institute of Standards and Technology Special Publication 800-88, Guidelines for
Media Sanitation, available at http://csrc.nist.gov/publications/, for discussion of shredding and
destruction of paper and other media.42 Contracting with a document-shredding service may be
an option for some programs. If a service is used, be sure that documents are shredded on site and
in the presence of a staff member. In all cases, a contract shredding or disposal company must be
bonded, and due diligence should be taken in the selection of the company.
GUIDING QUESTIONS:
»» Do staff members have access to a crosscutting shredder?
»» Is there a records-retention policy governing disposal of paper copies of confidential information?

STANDARD 4.3  Ensure that data-security policies and procedures address handling
of paper copies, incoming and outgoing mail, long-term paper storage, and data
retention. The amount of confidential information in all such correspondence should
be kept to a minimum and destroyed when no longer needed.
Policies should address retention of paper copies. If electronic copies exist, paper copies can be
destroyed when no longer needed, in accordance with established health department policies.
Provisions should be made to destroy copies using methods described in Standard 4.2.
GUIDING QUESTIONS:
»» Do policies describe procedures for managing incoming and outgoing mail containing
confidential information?
»» Do procedures specify minimum information criteria for paper copies?
»» What data retention policies apply to the data?
26

STANDARD 4.4  Limit access to secure areas that contain confidential public health
data to authorized persons, and establish procedures to control access to secure
areas by non-authorized persons.
Data security policies and procedures should specify who has access to secure areas. Policies
and procedures must also address the need for access by unauthorized persons (e.g., cleaning,
maintenance, and security staff ). Programs might consider providing cleaning crews with access
to secure areas only when authorized staff members are present or when confidential materials are
stored and protected.
GUIDING QUESTIONS:
»» Do policies adequately describe who has access to secure areas?
»» Do data security policies and procedures address access to secure areas and file storage areas
by cleaning crews and maintenance staff?
»» Are procedures in place to control access to secure areas by other unauthorized personnel?

STANDARD 4.5  Ensure that program personnel working with documents
containing PII in the field 1) return the documents to a secure area by close of
business, 2) obtain prior approval from the program manager for not doing so, or 3)
follow approved procedures for handling such documents.
Simple physical theft is a major cause of health information breaches. Transportation and use
of PII outside of secure areas should, therefore, be minimized and carefully controlled. Programs
employing field workers should establish specific procedures for:
ƒƒ Working with PII outside of secure areas
ƒƒ Obtaining or documenting a manager’s approval to do so
ƒƒ Physically securing documents containing PII that remain in staff custody after usual
work hours
GUIDING QUESTIONS:
»» Do policies include procedures for securing documents containing PII when they cannot be
returned to a secure work site by the close of business?
»» Do policies outline specific reasons, permissions and physical security procedures for using,
transporting and protecting documents containing PII in a vehicle or personal residence?

27

STANDARD 4.6  Ensure that documents with line lists or supporting notes contain
the minimum amount of potentially identifiable information [PII] necessary and,
if possible, that any potentially identifiable data are coded to prevent inadvertent
release of PII.
To the extent possible, PII should not be removed from a secure location or accessed from
an unsecure area. However, some public health activities (e.g., field investigations and service
provision) require taking such information into unsecure areas. In these situations, the use of PII
should be limited and appropriate security measures implemented.
GUIDING QUESTIONS:
»» Is access to public health notes and investigation information containing identifiable data limited
to personnel requiring the information for an approved purpose?
»» Are confidential data elements coded?

5.0  ELECTRONIC DATA SECURITY
Implementation of electronic data security standards will be conducted in a rapidly evolving
technological environment. While technology is changing, the following elements will remain
important to consider when developing policies.
Access: Access to surveillance data needs to be planned in advance. Access groups can be set
up in virtually all IT environments, which will allow the program to designate users with different
levels and types of rights. Programs should specify who has access to various data, under what
circumstances, and how the identity of users are authenticated. For example, they might stipulate
that identifiable data should be accessed only from a properly secure network server rather
than from local workstations. Isolated segments or domains can be implemented, which limits
access to those in selected groups. They also might limit the times during which data can be
accessed, restrict the copying or downloading of data, and set up other controls as needed. Due
to the technical nature of these control measures, IT personnel should be involved in the initial
assessment and both the formulation and implementation of electronic data security policies.
Appendix G also addresses electronic data security issues.
Encryption and Backups: Although encryption may not be needed for data on a production
registry or surveillance data system located within a secure area and separate from any
networks, encryption is still recommended. Any data in such a registry or system do need to
be encrypted before being transmitted or downloaded to approved locations and while being
used in the field on laptops or similar devices. Although surveillance databases and other files
with identifying information need to be backed up, back-up databases and files should be
encrypted in accordance with federal encryption standards and stored in a secure location.
Bonded storage companies can be used to store back-up files of identifiable data as long as
the data are encrypted according to standard operating procedures. Encryption is one means
of increasing data security. Backup data should also be encrypted before being copied to a
28

secure location. All encryption methods need to meet standards detailed in Federal Information
Processing Standards (FIPS) Publication 197, Advanced Encryption Standard (AES).
(See http://csrc.nist.gov/publications/fips/fips197/fips-197.pdf.) 43
Evolving Technologies: Many public health workers handle PII in the field while pursuing public
health activities, and as technology continues to evolve, use of PDAs, electronic tablets, and
notebook computers may involve data stored on portable devices. Programs must therefore
plan for migration from paper-oriented to electronic systems that meet established and evolving
electronic and procedural security standards. Forward-looking confidentiality and security
protocols should include provisions for phones, PDAs, tablets, and workbooks that take clientidentified data to the field and allow for real-time updates, reporting, and data entry from field
sites as well as by medical staff in examination rooms. These protocols should also provide
accountability measures to ensure that staff members employ this secured, confidential data in
appropriate locations while in the field. Programs may review National Institute of Standards and
Technology Special Publication 800-124, Guidelines on Cell Phone and PDA Security, available at
http://csrc.nist.gov/publications/) when developing policies.44
Surveillance programs will be increasingly using electronic medical records and electronic
laboratory records to complete case reports. Many health departments already have or are
considering public health information exchanges which have the potential to enhance surveillance
data collections. When implementing these activities programs should ensure secure methods are
used and policies and procedures ensure security and confidentiality of data. Additional resources
on electronic data exchange can be found at http://www.cdc.gov/ehrmeaningfuluse/ and the
public health information network (http://www.cdc.gov/phin/ ).
Secure Transmission: Data to be transmitted across defined, secure boundaries should be
transmitted through the use of secure methods, such as secure data networks (SDNs), virtual
private networks (VPNs), and secure file transport protocol (SFTP). Although these methods can
be used to encrypt data in transit, they do not encrypt data before they are sent or after they are
received. Therefore, if either the sender or the recipient of the data is not part of a defined security
zone appropriate for sensitive data, data should be encrypted by another method prior to being
transmitted. Since transmission of data via cell phones or PDAs is similarly insecure, identifiable
information should also not be sent with these devices.

STANDARD 5.1  Ensure that analysis data sets that can be accessed from outside
the secure area are stored with protective software (i.e., software that controls data
storage, removal, and use), and verify removal of all personal identifiers.
Analysis data sets should be stored on a separate server or segmented local area network (LAN).
At a minimum, analysis data sets should be located on a virtual server and all personal identifiers
should be removed. The inclusion of sensitive or potentially linkable data elements such as a lab
ID, accession number, or case report number should be limited to those required for analysis and
should not be included in analysis data sets. Given the increasing ability to re-identify records by
matching between multiple publically accessible databases, consultation with a de-identification
expert may be useful before making de-identified databases publically available.
Encryption of analysis data sets, when not in use, is not necessary if personally identifiable data
29

elements have been removed. However, encryption is recommended as additional protection
from accidental or purposeful misuse.
GUIDING QUESTIONS:
»» Are roles assigned to selected individuals to create analysis data sets to minimize the
number created?
»» What measures have been taken to ensure that analysis data sets are created, stored, and
accessed securely?
»» Do data security policies describe the data elements that may be included in analysis data sets?

STANDARD 5.2  Ensure that any electronic transfer of data is approved by the ORP
and subject to access controls, and that identifiable data are encrypted before being
transferred.
This standard applies particularly to situations in which data are obtained electronically from
sources outside the health department (e.g., electronic laboratory data, electronic health records,
Web-based systems, hospitals, and other large providers). Extracts from these systems should
meet the minimum security standards outlined in this document. Electronic records should
be protected through security devices such as sign-on passwords, encryption, and audit trails.
External sources should be encouraged to review their procedures. Approved data transfer
methods should be used when designing electronic reporting mechanisms for laboratories,
providers, etc.
As possible, data with PII should be encrypted while in transit and when at rest. Ideally, datatransfers should be done over a secure data network (SDN), virtual private network (VPN)
connection with certificates on both the sending and the receiving ends, or similar secure
connection. At a minimum, data transfer should be performed via a secure application such as a
file transfer protocol (FTP) for which certification is required on at least one end.
Electronic files being stored for future use (e.g., ancillary data and working laboratory data sets)
should be encrypted until needed. If these files are needed outside the secure area, use of realtime encryption or an equivalent method of protection is recommended.
GUIDING QUESTIONS:
»» Are routine electronic transfers of data containing identifiable data done through secure
methods, and are data encrypted before transfer?
»» Are encryption methods that meet Advanced Encryption Standards (AES) always used to move
identifiable public health data? (See http://csrc.nist.gov/publications/fips/fips197/fips-197.pdf.)
»» Are ancillary or working data sets containing PII encrypted when not in use?

30

STANDARD 5.3  Before transferring electronic data containing PII, ensure that the
data have been encrypted with use of an encryption package that meets Advanced
Encryption Standard (AES) criteria and that the data transfer has been approved by
the appropriate program official or ORP. No electronic data containing identifying
information should be transferred without being encrypted.
PII must be safeguarded to maintain confidentiality. The preferred method of securing
data is with whole-device encryption that fulfills FIPS 140-2 standards available at
http://csrc.nist.gov/publications/fips/fips140-2/fips1402.pdf. Device encryption ensures that
“remnants” of any files that were opened or deleted from the device are fully secure. File
encryption is adequate only when used in connection with proper physical protections. The least
appropriate security measure is to rely totally on physical protection and should be used only
in highly secure and restricted environments. The decision to use physical protections over an
encryption solution is a risk-based decision, as these protections cannot completely remove the
risk of theft or loss of sensitive data.
Confidential, individual-level public health data should be transferred via more secure electronic
transfer methods, personal communication, or hard-copy mail delivery when at all possible. At a
minimum, programs that choose to fax paper documents containing PII should take steps to make
it as secure as possible. Partners who submit identifiable data to health departments also need to
be informed of acceptable methods of transfer. Guidelines for the use of facsimile machines are
included in Appendix F.
E-mailing of unencrypted personally identifiable information is not allowed. Unintended release of
confidential unencrypted e-mail may result. E-mail inadvertently might be sent to an unintended
recipient, and even an encrypted e-mail might result in unintended access. Health departments
must also adhere to relevant “sunshine” laws regarding access to government e-mails. If public
access to e-mail is required, the process of publicly contesting the release of information is not
likely to play out well to the general public.
GUIDING QUESTIONS:
»» Has identifying information been removed from unencrypted data before they are
transferred electronically?
»» Are encryption methods that meet AES standards always used in the transfer of
identifiable data?
»» Are procedures in place for limiting faxing of confidential data? If faxes are used, what
additional procedures are in place to secure the information and ensure that it is sent to
the intended recipient only?
»» Do data policies address e-mailing of public health data?
»» Is identifying information always removed from data or encrypted prior to the data being
sent by e-mail?

31

STANDARD 5.4  Use encryption software that meets federal AES standards to
encrypt data with PII on all laptops and other portable devices that receive or
store public health data with personal identifiers.
PII on a laptop must be encrypted and stored on an external storage device or removable hard
drive. The external storage device or hard drive containing the data must be separated from the
laptop and held securely when not in use. The decryption key must not be on the laptop. Portable
devices without removable or external storage components must have encryption software that
meets federal AES standards. All removable or external storage devices containing identifiable
public health data must:
ƒƒ Include only the minimum amount of information necessary to accomplish assigned tasks
as determined by the designated official or ORP
ƒƒ Be encrypted or stored under lock and key when not in use
ƒƒ Be sanitized immediately following a given task (except for those used as back-ups)
Before any portable device containing sensitive data is removed from a secure area, the data
must be encrypted. Methods used to sanitize a storage device must ensure that any data on the
device cannot be retrieved by using “undelete” or data retrieval software. Hard drives, flash drives,
or any other storage media of computers that once contained PII must be sanitized or physically
destroyed before the computers are labeled as excess or surplus, reassigned to other staff
members, or sent off-site for repair. This requirement also applies to copiers, printers, fax machines,
or other equipment that contain internal storage devices.
GUIDING QUESTIONS:
»» Do policies describe when PII may be stored on external devices?
»» Are stored data appropriately encrypted?
»» Do policies describe how to sanitize or physically destroy storage devices when tasks are
completed?
»» Do policies restrict use of photographic and video devices in areas containing PII, especially in
areas where there are paper documents? Do policies explicitly include cell phones and PDAs with
picture and video storage capability?

32

STANDARD 5.5  Ensure that data policies include procedures for handling incoming
and outgoing facsimile transmissions. Minimize inclusion of PII in fax transmissions,
and destroy hard copies and sanitize hard drives when no longer needed.
ƒƒ The faxing of identifiable information is allowed but should be avoided when possible (see
Appendix F for guidelines on the use of facsimile machines). The sender of a fax cannot
be certain that the fax will actually be received by the person for whom it was intended.
Although encrypted fax machines are available, they would be needed at both ends of an
encrypted fax transmission.
ƒƒ When a fax is necessary, minimize inclusion of confidential information.
ƒƒ Take precautions (such as a telephone call) to ensure that the recipient is present to receive,
and confirm receipt of, the fax.
GUIDING QUESTIONS:
»» Have all alternatives to faxing PII been explored?
»» Have confidential data items been kept to a minimum?
»» Have steps been taken to ensure that a person is standing by to receive and confirm receipt
of a fax containing PII?
»» Have the steps in Appendix F been followed to ensure secure use of fax machines?

Appendix A. Glossary
Access: Ability or means needed to read, write, modify, or communicate data/information.
Access control: Cohesive set of procedures designed to ensure that anyone with access to identifiable
public health data:
ƒƒ Is the person he or she claims to be (authentication),
ƒƒ Has a verified public health need to have access to the data in question, and
ƒƒ Has been authorized to access the data and is doing so from an authorized place using an
authorized process
Advanced Encryption Standard (AES): This standard specifies the algorithm that can be
used to protect electronic data and is issued by the National Institute of Standards and
Technology (NIST). Publication 197 of the Federal Information Processing Standards (FIPS)
(http://csrc.nist.gov/publications/fips/fips197/fips-197.pdf ) contains the specifications of the
AES, which can encrypt (encipher) and decrypt (decipher) information. Encryption converts data
to an unintelligible form called cipher text; decrypting the cipher text converts the data back to
its original form, called plaintext. The AES algorithm is capable of using cryptographic keys of 128,
192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. NIST publication 140-2 details
the protection of a cryptographic module within a security system necessary to maintain the
confidentiality and integrity of the information protected by the module
http://csrc.nist.gov/publications/fips/fips140-2/fips1402.pdf.
Aggregated data: Information—usually summary statistics—that might be compiled from personally
identifiable information (PII) but is grouped so as to preclude identification of individual persons.
Analysis dataset: Set of aggregated data created by removing identifying information (e.g., names,
addresses, ZIP codes, telephone numbers) so that the data cannot be linked to a specific person but
can still be used for data analysis.
Authorized access: As determined by the ORP or designee, permission granted to an authorized
person to see confidential or potentially identifiable public health data, based on the public health role
of the individual and their need to know.
Authorized person: Person who has been granted authorized access to confidential information
to carry out assigned duties and for whom a current, signed, approved, and binding nondisclosure
agreement is on file.
Breach: A departure from established policies or procedures, or a compromise, unauthorized
disclosure, unauthorized acquisition, unauthorized access, or loss of control of personally identifiable
information (PII). A breach is an infraction or violation of a policy, standard, obligation, or law. A breach
in data security would include any unauthorized use of data, even aggregated data without names. A
breach may be malicious or unintentional.
Breach of confidentiality: A breach, as defined above, that results in the release of PII to unauthorized
persons (i.e., employees or members of the general public).
Breach of Personally Identifiable Information: Defined by OMB Memorandum 07-16, Safeguarding
Against and Responding to the Breach of Personally Identifiable Information, to include the loss of
39

control, compromise, unauthorized disclosure, unauthorized acquisition, unauthorized access, or any
similar term referring to situations where persons other than authorized users and for an other than
authorized purpose have access or potential access to personally identifiable information, whether
physical or electronic.
Confidential information: Any private information about an identifiable person who has not given
consent to make that information public.
Confidentiality: Protection of personal information collected by public health organizations. The
right to such protection is based on the principle that personal information should not be released
without the consent of the person involved except as necessary to protect public health.
Confidentiality agreement (or nondisclosure agreement): A contract between at least two
parties that outlines confidential material, knowledge, or information that the parties wish to share
with one another for certain purposes, but wish to restrict access to by third parties. It is a contract
through which the parties agree not to further disclose information covered by the agreement.
Data dissemination: Any mechanism by which data (typically in aggregate form) are made available
to users. Includes mechanisms whereby data are released to users as well as mechanisms whereby
data are made available without being released.
Data encryption standard (DES): Algorithm that encrypts and decrypts data in 64-bit blocks. Since
the DES always operates on data blocks of equal size and uses both permutations and substitutions
in its algorithm, it is both a block cipher and a product cipher.
Data sharing: Granting certain individuals or organizations access to data that contain personally
identifiable information with the understanding that personally identifiable or potentially identifiable
data cannot be re-released further unless a special data-sharing agreement governs the use and rerelease of the data and is agreed upon by the receiving program and the data provider(s).
Data-sharing agreement: Mechanism by which a data requestor and data provider can define the
terms of data access that can be granted to requestors.
Data release: Dissemination of data either in a public-use file or as a result of an ad hoc request
which results in the data steward no longer controlling the use of the data. Data may be released
in a variety of formats including, but not limited to, tables, microdata (person records), or online
query systems.
Data steward: Person responsible for ensuring that data used or stored in an organization’s
computer systems are secure, classified appropriately, and used in accordance with
organizational policies.
Disaster recovery: Use of off-site computer operations (where copies of data and information
systems are stored) to recover data lost as the result of a catastrophe at the primary site of data
storage or to activate information systems to replace those lost.
Disclosure: Occurs when identifiable information concerning an individual is made known to a
third party. Disclosures may be authorized (as when a person has consented to the information
being so divulged), unauthorized (as when information is intentionally revealed to a party not
consented to by the person), or inadvertent (as when a tabulation or file is unintentionally made
available to the public that reveals or can be used to reveal personal information).
40

Encryption: Manipulation or encoding of information so that only parties intended to view the
information can do so. The most commonly available encryption systems involve public key and
symmetric key cryptography. In general, for both public and symmetric systems, the larger the key,
the more robust the protection.
Identifiable data or identifiable information: See Personally identifiable information.
Information security: Protection of data against unauthorized access. Effective security measures
are always a balance between technology and personnel management.
Legitimate public health purpose (see also public health data use): Population-based activity
or individual effort aimed primarily at the prevention of injury, disease, or premature mortality. This
term also refers to the promotion of health in the community, including: 1) assessing the health
needs and status of the community through public health surveillance and epidemiologic research;
2) developing public health policy; and 3) responding to public health needs and emergencies.
Public health purposes can include analysis and evaluation of conditions of public health
importance and evaluation of public health programs.
Management controls: Controls that include policies for operating information technology
resources and for authorizing the capture, processing, storage, and transmission of various types
of information. They also may include training of staff, oversight, and appropriate and vigorous
response to infractions.
Need-to-know access: Access to data granted to a specific person on a case-specific basis where
exceptional circumstances exist that are not stipulated in program policies. This type of access should
be reserved for unusual situations and granted only after careful deliberation by the ORP.
Non-public health uses of data: Release of data that are either directly or indirectly identifying
to the public; to parties involved in civil, criminal, or administrative litigation; to non-public health
agencies of the federal, state, or local government; or for commercial uses.
Overall responsible party (ORP): High-ranking official who accepts overall responsibility for
implementing and enforcing data security standards. This official should have the authority to make
decisions about program operations that might affect programs accessing or using the data, and
should serve as contacts for public health professionals regarding security and confidentiality policies
and practices. The ORP is responsible for protecting data as they are collected, stored, analyzed, and
released and must certify annually that all security program requirements are being met. The state’s
security policy must indicate the ORP(s) by name.
Personnel controls: Staff member controls, such as training, separation of duties, and background
checks, that are used as part of information security and management controls.
Personal identifier: Information that allows the identity of a person to be determined with a
specified degree of certainty. This could be a single piece of information or several pieces of data
which, when taken together, may be used to identify an individual. Therefore, when assembling or
releasing analysis data sets, it is important to determine which fields, either alone or in combination,
could be used to identify a person and which controls provide an acceptable level of security.

41

Personally identifiable information (PII): As defined by National Institute of Standards and
Technology Special Publication 800-122, Guide to Protecting the Confidentiality of Personally
Identifiable Information (PII), available at http://csrc.nist.gov/publications/: ”Any information about an
individual maintained by an agency, including (1) any information that can be used to distinguish or
trace an individual‘s identity, such as name, social security number, date and place of birth, mother‘s
maiden name, or biometric records; and (2) any other information that is linked or linkable to an
individual, such as medical, educational, financial, and employment information.“
Physical access controls: Physical barriers such as locked doors, sealed windows, password-protected
keyboards, entry logs, guards, etc., used to help limit access to confidential information.
Public health surveillance: The ongoing, systematic collection, management, analysis, and
interpretation of health-related data followed by their dissemination to those who need to know in
order to: 1) monitor populations to detect unusual instances or patterns of disease, toxic exposure,
or injury; 2) act to prevent or control these threats; and 3) intervene to promote and improve health.
The term applies to both electronic and paper-based systems.
Public health data use (see also legitimate public health purpose): Includes the variety of ways
public health data may be used to achieve public health goals/purposes. A principal public health
data use at state and federal levels is for epidemiologic monitoring of trends in disease incidence
and outcomes. This includes collection of data and evaluation of the collection system, as well as the
dissemination of aggregate trends in incidence and prevalence by demographic, geographic, and
behavioral risk characteristics to assist the formulation of public health policy and direct intervention
programs. Public health data uses may also include data used to initiate or provide treatment and
prevention services.
Records retention policy: A policy that stipulates how long paper and electronic records should be
kept before they can be archived or destroyed.
Role-based access: Access to specific information or data granted on the basis of a person’s job
status or authority. This control mechanism protects data and system integrity by preventing access
to unauthorized applications. Granting access based on roles within an organization, rather than by
individual users, simplifies an organization’s security policy and procedures and helps avoid granting
need-to-know access to individuals.
Secure(d) area: Work space with physical access controls in which confidential data are kept and/or
used with access granted only to authorized persons. The configuration of a secure(d) area depends
on resource and other program considerations (e.g., availability of physical space, locks, file cabinets,
walls, doors, and other barriers.)
Security: Protection of public health data and information systems to prevent unauthorized release
of identifying information and accidental loss of data or damage to the systems. Security measures
include measures to detect, document, and counter threats to data confidentiality or the integrity of
data systems.
Syndemic: Synergist interaction of two or more conditions that contribute to an excess burden of
disease in a population.
Virtual private network (VPN): Network of computers that uses encryption to scramble all data sent
through the internet—making the network “virtually” private.

Checklists for Assessment of Data Security and
Confidentiality Protections
INITIAL ASSESSMENT
This checklist can be used to guide the initial assessment of a program’s compliance with the Standards for
Data Security and Confidentiality. This will be particularly useful for state and local public health programs
that currently lack data security and confidentiality policies and procedures.
As indicated previously in this document, the initial assessment should be conducted by a team led by the
ORP(s). The team should include:
ƒƒ Program managers, directors, or equivalent leaders from participating programs
ƒƒ Other representatives of participating programs
ƒƒ Staff members with technical expertise in data security
ƒƒ IT staff
The initial assessment should include the following steps:
ƒƒ Identify key individuals and designate an ORP
ƒƒ Review current security-related materials (e.g., written policies and procedures)
ƒƒ Review relevant state and local laws that might affect data security and confidentiality policies
ƒƒ Identify any policies or procedures that are either barriers to information sharing or sources of data
security weaknesses
ƒƒ Consult standard operating procedures (SOPs) from other programs that might be useful sources of
ideas or suggestions for procedural changes
ƒƒ Review any history of data security breaches or near-breaches, and associated lessons learned
ƒƒ Assess physical security and define the secure area
ƒƒ Assess electronic security protections and methods of data transfer and storage
ƒƒ Assess factors related to security of information in the field, as appropriate
ƒƒ Assess training needs

CONDUCTING AN INITIAL ASSESSMENT: STEPS AND GUIDING QUESTIONS
Identify key
individuals and
designate an ORP
Review current
policies and
gather resources

Identify weaknesses
and barriers

Have key individuals, including program managers, directors, persons responsible for
information and system security, and appropriate technical staff members, been identified?
Has an ORP(s) with ultimate decision-making authority and responsibility for reconciling
differences in policies and procedures across programs been identified?
Have relevant policies, data-sharing agreements, and standard operating procedures been
compiled and reviewed?
Have relevant laws, rules, and regulations been considered?
Have areas of weakness and specific topics that need additional clarification been identified?
Have barriers to data sharing been identified?
Have potential solutions to these barriers, including possible policy revisions, been noted?
What is the work-space configuration?
What is the path of public health data from collection and entry into the program’s physical space
through data entry and storage?

Assess physical
security and define
the secure area

What happens to case report forms received from providers? How are case report forms completed
by health department staff handled? Is information obtained by phone or other electronic format?
If so, how are hard copies or electronic media physically secured? Are electronic devices used, such
as PDAs or laptops? If so, how are these physically secured?
How is the area that houses identifiable data secured?
Who has access to the physical space, who needs access, and for what purpose?

Assess electronic
security, protections,
and methods of data
transfer and storage

Assess training
needs

Who or what roles need access to identifiable data? At what stage is their access required?
Who needs access to electronic databases with identifiable data?
Who needs access only to de-identified or analysis data sets?
Who teleworks and what level of access do they need? Are electronic protections in place
for remote access?
Which individuals must take identifiable information in the field or outside of the secure
physical area or health department? How is that information brought back into the office and
what happens when it arrives?
Does field work involve information on paper or electronic data on laptops or other
storage devices?
What electronic protections are in place during data transfer? Is encryption used? If so, when
are data encrypted? Are data encrypted while at rest?
Are data ever transported between locations across secured boundaries such as a secure
data network (SDN), virtual private network, or Secure File Transfer Protocol (SFTP)?
Do all programs involved have specific security and confidentiality training? How often is it
conducted and who does it?
What additional training will be required if policies are modified?
Do other types of employees need to be trained (e.g. mail room staff, maintenance and
cleaning staff, security staff, IT staff [in-house and contracted services])?
How often are training materials updated?

44

Appendix C.
Data Sharing Scenario
The following scenario is an example of data sharing between HIV and STD programs. In this scenario, a new
case patient with HIV infection is identified through HIV surveillance and is offered partner services by the STD
program. This scenario will not apply to all programs, but rather highlights one method for data sharing.
State and local health departments are notified of previously unknown patients with HIV infection by public
or private laboratories that submit electronic or hard-copy laboratory and/or case reports indicative of HIV
infection. The reports may be sent to a state health department, where HIV and STD staff may assign the
newly identified patient to a local health department for partner services. Sometimes a laboratory will send
the report directly to a local health department, and the staff there may immediately begin the process of
offering partner services.
This example illustrates the information flow when a state health department receives an electronic laboratory
report of HIV infection and shares that information with the local health department staff for partner services.
At the Home State Health Department, the STD program conducts partner services for both HIV and STD.
However, the HIV surveillance unit operates separately from the STD program, thus requiring data sharing
between programs. As an initial step, Jim, the HIV surveillance coordinator at the Home State Health
Department, receives an electronic laboratory report for what appears to be a new case patient with HIV
infection. He conducts a search through eHARS and confirms that this patient has not been previously reported.
When Jim enters the HIV case report information into eHARS, he notes that there is incomplete or missing
information on the laboratory report. Referring to the Home State Data Sharing Plan, Jim provides the minimal
information that he has on this case to the State Health Department STD program which forwards it to the Field
Supervisor in the STD program at the Small City Health Department which is in the jurisdiction in which the
patient resides. Jim sends a hard copy of the HIV case report form to the STD program with the patient’s name,
date of birth, gender, home address and telephone number, and current HIV test information. He also includes a
request to obtain missing demographic, risk factor, HIV testing, and HIV treatment information from the patient
during the partner services investigation.
The state health department HIV surveillance unit provided enough information to initiate a field record which
is then assigned to a team of Disease Intervention Specialists (DISs). Jane, a DIS in the local health department’s
STD program, receives the HIV field record from her First-Line Supervisor (FLS) and conducts a record search
to determine whether the patient has been previously notified of their HIV status, received Partner Services, or
been reported to the health department for any other STDs. Jane determines that this individual has not had
any of these encounters with the health department. Jane goes to the field to locate, notify, and interview the
client. Jane locates and interviews the client and provides counseling and Partner Services. Jane makes sure
to document any missing demographic and risk information to include in the case records and to share the
missing information with HIV surveillance.

55

During the investigation, Jane also offers the client STD testing and referral for medical management
of HIV infection, which typically includes TB screening and may include Hepatitis B vaccination or
Hepatitis C screening. Upon returning to the local health department, Jane completes the case
documentation and enters the data into the electronic STD data management and reporting
system. Jane shares the results of the field investigation with the STD Field Supervisor and provides
documentation of the missing HIV information to the HIV surveillance unit, according to instructions in
the Home State Health Department’s Data Sharing Plan.
The following flow diagram outlines the above scenario.

Appendix F.
Guidelines for the Use of Facsimile Machines*
Although facsimile (fax) equipment and software can enhance the quality of health care by
facilitating rapid transmission of health information, this same mode of transmission opens up the
possibility that information will be misdirected or intercepted by persons for whom access is not
intended or authorized. In recent years, numerous reports have described events wherein patient
health records were inadvertently faxed to a wrong location (e.g., bank or retail store) rather than the
intended recipient. The following recommendations will help minimize the risks associated with use
of facsimile machines.
ƒƒ Establish fax policies and procedures based on federal guidelines, state laws and regulations,
and consultation with legal counsel, as needed.
ƒƒ Take reasonable steps to ensure that the fax transmission is sent to the intended destination.
As possible, pre-program and periodically audit and test destination numbers to eliminate
errors in transmission from misdialing and outdated fax numbers. Periodically, remind frequent
recipients of PII to notify the program of any changes in fax number. Train staff to double check
the recipient’s fax number before pressing the ‘send’ key.
ƒƒ Provide education and training to staff on the program’s fax policies and procedures. This
includes educating private providers and laboratories that report information to public health
programs. Take reasonable operational safeguards to alert staff of faxing procedures. For
example, affix brightly colored stickers to fax machines reminding staff of key fax policies (e.g.,
need for a cover sheet; verification of recipient’s fax number; and procedures to implement if
an incoming fax has been received in error).
ƒƒ Require all fax communications be sent with a cover sheet that includes name and contact
information of the sender and the recipient, confidentiality disclaimer statement, and
instructions on what to do if the document is received in error (see Sample Confidentiality
Disclaimer below).
ƒƒ If a fax transmission fails to reach the recipient, check the internal logging system of the fax
machine to obtain the number to which the transmission was sent. If the sender becomes
aware that a fax was misdirected, contact the receiver and ask that the material be returned or
destroyed. Investigate misdirected faxes as a risk management occurrence or security incident,
inform the ORP, and log the incident for remediation/mitigation.
ƒƒ Locate fax machines in secure areas.
ƒƒ Ensure that data security policies include procedures for maintaining and disposing of paper
fax transmissions.

Appendix G.
Ensuring Data Security in Nontraditional Work Settings

Electronic Data Security
The following restrictions must be followed when dealing with personally identifiable information
(PII) in a telework environment.
ƒƒ The media on the device being used to access PII must be fully encrypted; encryption of
individual files is not adequate.
ƒƒ Personal computers or personal electronic media should not be used for data storage.
Data-storage devices must be issued by the agency. On an agency-issued device,
internet service provider (ISP) or personal network equipment may be used for internet
connectivity.
ƒƒ Agency-issued computers must be configured to prevent installation of software by
persons other than agency IT staff.
ƒƒ The agency must have properly configured firewalls installed on computers to be used
outside of the agency’s protective boundaries.
ƒƒ PII should never reside on a device that is ever connected to the internet either directly or
indirectly outside the agency firewall.
ƒƒ PII may be analyzed if technology is used to access and analyze remotely with only
displays of data and results being shown on the device. Citrix applications are an
example of this technology.

Telework
Teleworking is a complex issue, particularly because most of the work performed by surveillance
and field staff involves patient identifiers or potential identifiers. Whenever possible, work with
surveillance data should be performed at the worksite, with recommended physical, electronic,
and procedural protections. Even though IT staff may make it possible to have the same access at
home that is available in the office, that does not mean that the access or home workplace is just as
secure.
Nonetheless, current workplace trends are moving strongly toward teleworking, even for
individuals working with PII. Therefore, programs should coordinate with IT and their own staff to
ensure that home access meets the same confidentiality and security protections as the office work
space. The work environment of the teleworker should be subject to an audit to verify minimum
physical security protections.

63

Recommended characteristics of a telework location include:
ƒƒ Limited access (e.g., a locking door) in a private area. In a home, this means a dedicated room with
no access by unauthorized persons. The ability to observe PII on device displays must be restricted to
only the teleworker.
ƒƒ No hard-copy storage of client-identified data. If hard copies of any documents must be stored in a
telework location, they should be stored in double-locked file cabinets, large and heavy enough to
render them immobile. Hard copies of documents containing PII must be shredded using a cross-cut
shredder and should never to be left in an unsecured area.
ƒƒ The work space must be configured to allow confidential conversations.
»» PII stored and transmitted via a computer with encryption software at least equal to the
currently accepted level of encryption used in the regular workplace
»» If the computer is connected to the internet with Wi-Fi, access to the Wi-Fi connection must
be secure.

Field/Clinic work
Many public health workers handle PII in the field while pursuing public health activities. Traditionally,
most of that data has been in hard copy, but the evolving technology of PDAs, electronic tablets, and
notebook computers is driving many programs away from traditional paper data to e-data stored on
portable devices. Programs must therefore plan for migration from paper-oriented to electronic systems
that meet established and evolving electronic and procedural security standards. Forward-looking
confidentiality and security protocols should include provisions for phones, PDAs, tablets, and workbooks
that take client-identified data to the field and allow for real-time updates, reporting, and data entry
from field sites as well as by medical staff in examination rooms. These protocols should also provide
accountability measures to ensure that staff members employ this secured, confidential data in appropriate
locations while in the field. Programs may review Guidelines on Cell Phone and PDA Security, National
Institute of Standards and Technology Special Publication 800-124, available at http://csrc.nist.gov/
publications/, when developing policies.

Remote work
In the case of emergency or outbreak responses, staff may be detailed to work sites that have not been
prepared to meet data security standards. The host area and detailed staff should ensure that the work site
is made as secure as reasonably possible in terms of physical, electronic, and procedural security.
