Primary care physicians as providers of frontline genetic services.

Due in part to shortages of health care professionals with expertise in genetics, primary care physicians will assume a greater role in providing frontline genetic services as genetic tests for more diseases become available. I report some preliminary findings from a national survey of primary care physicians, psychiatrists, medical geneticists and genetic counselors. As expected, no group of nongenetics specialists had as much knowledge as geneticists. Nongeneticist physicians with the greatest exposure to patients with genetic problems had more knowledge than physicians without such exposure. Non-geneticist physicians were more likely to be directive in counseling than geneticists. Problems for future research are enumerated.
