Issues in implementing prenatal screening for cystic fibrosis: results of a working conference

To summarize a conference convened to examine how cystic fibrosis screening might appropriately be introduced into routine prenatal practice. Participants included experts from various relevant disciplines. Systematic reviews and data from individual trials were presented; issues were identified and discussed. Judged by published criteria, prenatal cystic fibrosis screening is suitable for introduction. Screening can be performed cost-effectively by identifying racial/ethnic groups at sufficient risk and then using either of two models for delivering laboratory services. Validated educational materials exist. Ethical issues are not unique. Once adequate facilities for patient and provider education, testing, counseling, quality control, and monitoring are in place, individual programs can begin prenatal screening for cystic fibrosis.
