Data‐Driven, Patient‐Centred HIV Care Supports Sustained Viral Suppression: A Retrospective Programme Analysis From the Medical Research Foundation of Trinidad and Tobago

INTRODUCTION: Achieving and sustaining viral suppression among people living with HIV remains central to global HIV control efforts. Despite global 95-95-95 targets and the scale-up of differentiated service delivery (DSD) models, many programmes continue to face structural and system-level barriers to sustained treatment outcomes. Evidence on longitudinal HIV treatment outcomes using routinely collected programme data remains limited in Caribbean settings. This study aimed to describe longitudinal trends in HIV treatment outcomes at the Medical Research Foundation (MRF), a large HIV treatment site in Trinidad and Tobago. METHODS: A retrospective descriptive analysis was conducted using de-identified electronic medical record (EMR) data for all clients receiving antiretroviral therapy (ART) at MRF. Data were analysed across seven fiscal quarters (FY2024 Q2-FY2025 Q4). The programme delivers differentiated, patient-centred HIV care supported by routine EMR monitoring and quarterly programme performance reviews. Key indicators included ART coverage, viral load (VL) testing coverage, viral suppression (VL
