The selective utilization of prenatal genetic diagnosis. Experiences of a regional program in upstate New York during...

The regional prenatal diagnosis program of the Finger Lakes Health Systems Area in upstate New York has been monitored since its start in 1971. By the end of 1980, more than 1,250 diagnostic procedures had been successfully completed. Based on analyses of regional vital statistics, genetic services data, repeated surveys of obstetricians, and an ongoing survey of recent mothers older than 34 years of age, the authors concluded that: 1) in the study region, most women with an indication for prenatal diagnosis because of age are aware of the possibility of prenatal diagnosis; 2) the majority of obstetricians discuss amniocentesis with their patients; 3) after a period of rapid growth the utilization rate in the study region reached about 40% in 1981; 4) nonuse of prenatal diagnosis is based mostly on a patient's decision rather than system deficiencies; and 5) a community approach to increase utilization will have to focus on how to provide a supportive social climate for these services rather than on increasing awareness among potential patients or more referrals by providers.
