PROTOCOL FOR PHYSICAL AND DYSMORPHOLOGY EXAMINATION
(revised 11-14-05)
Objective
The recommended format is intended to facilitate recording data from anthropometric and dysmorphology examination, and determine if a subject (or cohort control) is likely to have a genetic syndrome. The physical examination will include anthropometrics (height, weight, head circumference) and standardized dysmorphology examination.
Methods
Measures
Physical anthropometric measurements according to standards described in training manual.
Data will be recorded for physical and dysmorphology examination in the data recording form (see Appendix).
Measurement and description of specified features (including face, hands, feet and others) in standardized fashion by use of digital camera and measurement software. Measurements will be recorded in datasheets.
Procedures
Assessment Team
Qualified examiner (see below for qualifications) for dysmorphology examination and photography.
Pediatric clinician for supervision of physical measurements and recording data of dysmorphology examination
Each center will include an experienced pediatric clinician who will train and supervise the examiner.
Depending on the availability at each site, this clinician might be a Developmental or Behavioral Pediatrician, Child Neurologist, Child Psychiatrist, Pediatric Nurse Practitioner or Pediatric Geneticist.
Each site will have access to a Consulting Pediatric Geneticist for assessment and analysis of photographs to determine if a syndrome is likely. Please see Quality Assurance section below.
Photogrammatic digital measurements:
Use of a digital camera (minimum 2.0 megapixels) and software program for measurement of specified dysmorphic features [web site is http://www.kuleuven.ac.be/bio/sys/carnoy/ ].
The centers will assure that the examiner will be trained in the use of the software program.
Photographs of child will include:
Views of face
Profile (both sides against dark background)
Full face portrait
Each hand with fingers spread
Feet (without shoes and socks, placed flat against a dark background)
Ear (length; from photograph – position, rotation morphology)
Standards for each photograph will be enumerated in the training manual.
Qualified Examiner:
Education: Master’s level (or equivalent degree) candidate preferred, with background in working with pediatric population(s) in a clinical department (e.g., genetics, other pediatric departments) or other research project involving children.
Experience:
Previous direct clinical experience in examining children, recording data, under supervision of pediatric clinician.
Completion of written and videotaped training curriculum according to published standards of measurement.
Experience observing in a pediatric clinical genetics clinic (e.g, craniofacial clinic or others), working with geneticist and/or genetics counselor for a minimum of 6 sessions.
Quality Assurance
To maintain quality and consistent data collection each of the CADDRE centers will:
Identify a clinician who will supervise and train the examiner(s), establish reliability, and oversee quality of data collection.
Identify a consulting Pediatric Geneticist who will be available to assist with training curriculum and evaluate photographs of subjects to confirm clinical impressions as needed.
Maintain a library of standard references (see reference list below).
Develop a written and videotaped curriculum for standards of physical measurements and data recording. Sample examinations will be videotaped as part of a curriculum for training examiners.
Measures of Quality assurance
Within the center – options to be considered will include (one or both of the following)
The clinical team will periodically compare direct clinical measurements by a geneticist or experienced examiner (using sliding anthropometric caliper) with photogrammetric digital measurements. The expectation of agreement (X% of measurement vs. number of trials to establish agreement) will be determined.
Duplicate photographs of the same child will be measured in sequence (by the same examiner) and/or by other examiners in the same program. The expectation of agreement X% of measurement vs. number of trials to establish agreement) will be determined.
Between centers – Interrater reliability measures (between centers) will be completed quarterly, with standards of agreement to be determined.
