Analysis of Existing Medical Record Data to Evaluate Coverage, Uptake, Benefits, and Costs of Differentiated Models of Service Delivery for HIV Treatment in Africa (Zambia)

What this Trial Is About

This research aims to evaluate differentiated service delivery (DSD) models for HIV treatment in high-prevalence countries, focusing on Zambia. It addresses key questions about how widely these models are offered, who is eligible, patient participation, health outcomes like viral suppression, resource use compared to traditional care, and sustainability without external support. The study is observational and analyzes existing medical record data to provide insights for future decision-making. The study collects routine medical records from electronic systems and paper charts without interacting directly with patients or providers. It compares patients enrolled in various DSD models to those receiving standard HIV care. There is no intervention administered; instead, existing data sets from the Ministry of Health and partners are analyzed to assess coverage, uptake, benefits, and costs of these service models. Participants include patients aged 15 years or older accessing HIV care within the data collection period, from any HIV transmission risk group. Researchers will review patient-months enrolled in DSD models over 6, 12, and 24 months. Since this is a data analysis study, no additional tests or visits are required. The analysis will inform on clinic efficiency, treatment outcomes, and long-term sustainability of differentiated HIV care delivery in Zambia.
