iHEART-SA Intervention Study (iHEART-SA)
The Integrating HIV and hEART Health in South Africa Intervention Study
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.

Detailed Description
Investigational interventions:
Implementation facilitation of improved hypertension screening and management in the HIV care setting through the iHEART-SA intervention model comprising:
- Information management system
- Task shifting
- Audit and feedback
- Healthcare worker education and training
- Patient education and support
Study design:
Cluster randomized stepped wedge effectiveness-implementation type 2 hybrid
Study objectives:
- Assess the short- and long-term effects of an implementation strategy (i.e., healthcare worker intervention) on the adoption and implementation of hypertension screening and treatment among healthcare workers
- Assess the short- and long-term effects of a clinical intervention (i.e., patient-level intervention) on patient blood pressure control among patients living with HIV and hypertension
Duration of participation: 27 months Study duration: 37 months
Intervention audience:
- Healthcare workers (nurses and doctors)
- Adult patients living with HIV from the 9 primary healthcare clinics
