Incorporation of genetics in primary care practice. Will physicians do the counseling and will they be directive?

To determine, by response to a scenario, how willing primary care physicians would be to counsel a couple about prenatal diagnosis of cystic fibrosis and how directive they would be about whether the couple should undergo prenatal diagnosis and whether the couple should terminate the pregnancy if the fetus is affected. Survey of a random sample of primary care physicians, psychiatrists, and genetics professionals in 10 geographically representative states. Sixty-five percent (N = 1140) of 1759 obstetricians, pediatricians, internists, family practitioners, and psychiatrists, and 79% (N = 280) of medical geneticists and genetic counselors. Respondents were evenly divided on whether they would counsel about prenatal diagnosis or refer to a genetic counselor (49.4% and 50.6%, respectively). Those who indicated that they would counsel were likely to have greater knowledge about genetics, greater confidence in communicating about genetics, and higher tolerance for ambiguity and were more likely to have completed their medical training since 1971 and to practice in a rural area. Forty-four percent of physicians would give an opinion about prenatal diagnosis. Men would be more likely to give an opinion than women (P < .005). Only 9.6% of respondents would give an opinion regarding abortion. These respondents were more likely to come from specialties with less exposure to genetics and to value attendance at religious services. Primary care physicians were more likely to give their opinions about prenatal diagnosis and abortion than genetics professionals. To the extent that attitudes are reflected in practice, genetic counseling may be more directive when provided by primary care physicians than by genetics professionals, unless primary care physicians' growing involvement in genetics changes their attitudes.
