Rapid human immunodeficiency virus testing in labor and delivery: a comparison of implementation models between 2 hospitals.

Despite the use of antiretroviral medications during the antenatal/perinatal period, 280 to 370 human immunodeficiency virus (HIV)-infected infants are born each year in the United States. Women who might transmit the virus to their infants are (1) those not offered antenatal testing due to perceived low risk; (2) those who are noncompliant with their antiretroviral regimen; (3) those with prophylaxis failures despite good compliance; and (4) those who present late to delivery without prenatal care. The Centers for Disease Control and prevention sponsored MIRIAD (mother-infant rapid intervention at delivery) to study rapid testing of women who present late in pregnancy and/or to labor and delivery with unknown HIV status.
