Compliance with voluntary prenatal HIV testing in a large health maintenance organization (HMO)

Results of a recent national clinical trial show that maternal-to-fetal transfer of HIV can be decreased threefold by prenatal, intrapartum, and neonatal treatment. The question is whether to make prenatal HIV testing compulsory or to encourage voluntary testing. Kaiser Permanente Northern California (KPNC), which has 2.5 million members, is part of a large health maintenance organization (HMO). In 1994, KPNC cared for 32,700 prenatal patients; 16,500 (50%) agreed to voluntary HIV testing. Compliance with testing ranged from 0% to 92% among the 31 KPNC locations. A study done by telephone survey identified three main factors favoring success of voluntary HIV screening: the ease and accessibility of HIV testing, a designated educator, and the presence of a registered nurse on the counseling team. In 1995, following feedback to the 31 facilities of the 1994 results, compliance rose to 19,800 of 31,300 prenatal patients (63%). KPNC, by encouraging counseled voluntary screening and following known positive cases, hopes to identify, track, and offer treatment options to all HIV-positive prenatal patients.
