Evaluating HITSystem 2.1 to Improve Viral Suppression in Kenya

HITSystem 2.1 is an intervention that tracks HIV+ pregnant women and their infants to improve the completeness and efficiency of PMTCT services. Key intervention features include: (1) SMS messages sent to enrolled women and mothers to support essential PMTCT services, (2) automated, algorithm-driven alerts for providers when per-guidelines PMTCT services are missed, and (3) automatic enrollment of infants into early infant diagnosis (EID) and linkage with maternal PMTCT file at documentation of infant birth to improve the continuum of care for HIV+ mothers and HIV-exposed infants. The HITSystem 2.1 intervention aims to facilitate complete PMTCT retention and viral load (VL) monitoring with prompt clinical action (adherence support, antiretroviral therapy (ART) regimen change) in the antenatal, delivery, and 6-month postpartum periods to increase viral suppression during windows critical for HIV prevention.
