Using qualitative data during the formative phase the IHEART-SA research study filled deficiencies in knowledge regarding: 1) what barriers exist to integrating hypertension care within the HIV care setting in South Africa and, 2) how a hypertension care intervention can be adapted to effectively and sustainably function in this care setting. These data have been used to design a context-relevant intervention package for implementation in the next phase of effectiveness-implementation testing, answering the research question: How does an intervention aimed at enhancing hypertension diagnosis and management in people living with HIV improve the delivery of guideline-recommended care in primary healthcare clinics in Gauteng, South Africa, and hypertension control among patients? The study will use an effectiveness-implementation study design. This design allows for the testing of strategies to promote integration of proven interventions in real-world practice (i.e., implementation strategies), while simultaneously assessing clinical effectiveness (i.e., patient level outcomes). For this the study will use a randomized cluster stepped-wedge study design where nine clinics (grouped in clusters of three) will be assigned to a time at which they initiate the intervention.
