Pilot study of the acceptability of cystic fibrosis carrier testing during routine antenatal consultations in general practice.

RESUMO

BACKGROUND: In 1989, the gene for cystic fibrosis was cloned and it became possible to detect carriers of the gene among the general population, including pregnant women. AIM: The aim of the pilot study was to assess the acceptability of integrating cystic fibrosis carrier testing into antenatal care by general practitioners at the first booking appointment. METHOD: Between 1 September 1991 and 31 August 1992, inclusive, all patients receiving routine antenatal care in a two-partner training practice in south Manchester were offered carrier testing for cystic fibrosis using a computer protocol for antenatal care developed by the practice. A questionnaire including a Spielberger state-trait anxiety inventory was sent to patients 2 weeks after they received the results of their carrier test, and interviews with the patients in their home were carried out 4 weeks and one year after they received the result. RESULTS: All but one patient (75 out of 76) booking before 14 weeks of pregnancy accepted the offer of cystic fibrosis carrier testing, and 96% (72 out of 75) felt that they had made the right decision and that they had enough time for discussion with their general practitioner before testing. CONCLUSIONS: Cystic fibrosis carrier testing can be successfully integrated into the antenatal booking appointment in general practice and is acceptable to patients. This is a model for other genetic screening opportunities resulting from advances in medical genetics.
