Abstract
Background: Uganda has successfully reduced pediatric HIV infections through prevention of mother-to-child transmission of HIV (PMTCT) programs, yet little is known about adherence to infant-specific components of interventions. We hypothesized that infants born to mothers receiving the WiseMama (WM) electronic drug monitoring (EDM)-based adherence intervention would have increased uptake of six-week post-natal nevirapine (NVP) infant prophylaxis and better adherence to six-week early infant diagnosis (EID) HIV testing.
Methods: At two sites in Uganda, the Wise Infant Study (WIN) prospectively followed an infant cohort. Infants were born to women enrolled in an RCT testing the effect of real-time reminders delivered via EDM on maternal adherence to antiretroviral therapy. We assessed intrapartum and discharge receipt of NVP prophylaxis using pharmacy and infant HIV DNA testing laboratory data.
Results: Of 121 women eligible for WIN, 97 (80%) consented and enrolled; 46 had been randomized to control and 51 to intervention. There were no differences in receipt of a six-week NVP supply (control 87%, intervention 82%, p = 0.53). Receipt of any NVP prophylaxis did not vary by delivery location (p = 0.35), and although 12% of infants were delivered at non-study health facilities, they were not less likely to receive NVP at discharge (p = 0.37). Among infants with a completed HIV test, there was no difference in mean time to first test (control 52 days (SD 18), intervention 51 days (SD 15), p = 0.86). Only one infant, in the control group, tested positive for HIV.
Conclusion and Global Health Implications: We found no significant differences in adherence to infant PMTCT practices between intervention and control infants with relatively high rates of NVP receipt albeit with suboptimal adherence to six-week EID testing. Further work is needed to ensure improved access, uptake, and follow-up of HIV-exposed infants in the Option B+ era.
