| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention Arm (HITSystem 2.1) | Participants enrolled at intervention sites will received HITSystem 2.1-supported PMTCT services through 6 months postpartum. Interventions received will include: text messages to patients to support medication adherence, appointment attendance, and hospital delivery and algorithm-driven alerts to notify providers when follow up services are missed.~HITSystem 2.1: 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. | 14 | 899 | EG000 |
| Group 2 | Control Arm (Standard of Care) | Participants enrolled at control sites will receive standard of care PMTCT services, with no HITSystem 2.1 tracking or follow up. | 22 | 740 | EG001 |
