A review of missed opportunities for prenatal HIV screening in a nationwide sample of health facilities in the Indian Health Service.

To better serve our patients, we sought to identify missed opportunities for prenatal HIV screening across Indian Health Service and potential ways to increase screening. Twenty-seven of 161 Federal or Tribal IHS health facilities were randomly selected. Each facility received a standardized set of commands to identify the charts of prenatal patients who were not screened for HIV according to the national Health Information Technology (HIT) platform. We reviewed 598 records at 27 sites of prenatal patients who were identified as not screened for HIV during their pregnancy. According to on-site chart review, nearly half (267/598, 45%) had been screened for HIV, and a slight majority (331/598, 55%) had not been screened. Among the 331 pregnant women not screened for HIV, about half had no HIV screening despite having had ≥2 prenatal care encounters and no screening exclusions (167/331, 50%). A majority of missed opportunities (118/167, 71%) had prenatal testing for other infectious diseases. Based on these results, the National HIV/AIDS program has encouraged increased bundling of HIV with infectious disease tests in prenatal laboratory panels. Improvements in documentation of HIV screening are expected with the IHS transition to electronic health records.
