Physician knowledge and attitudes towards molecular genetic (DNA) testing of their patients

Abstract

Responses varied by specialty, years from graduation, gender, and type of practice. Pediatricians and obstetricians were more knowledgeable about genetics, had more interaction with genetic services and were more supportive of their utility. A major proportion of physicians continue to rely upon undergraduate and medical school courses for knowledge, and the specialties showed different preferences for seeking information. A majority of physicians considered their knowledge of genetics to be adequate, but a minority were confident to provide genetic counseling for simple genetic scenarios. Relatively few had actually made use of DNA diagnostic services and there was relatively poor knowledge of what services were available.
