Brief summary
The InterCARE research project proposes to leverage a successful national ART program to develop an effective package to improve the uptake of established effective hypertension and CVD risk factors management interventions among PLWHIV in Botswana and other low- and middle-income countries. Being the first project of its kind in Botswana, if successful, the InterCARE package could be readily rolled out to health facilities nationwide to diagnose, treat, track, and support the estimated 25-30% Batswana with hypertension.
Detailed description
The InterCARE research project is in 2 phases: 1. Phase 1 is a pilot study to refine the 3 interventions mentioned above. This formative phase will take place between September 2021 and November 2022. Clinics staff will receive training on the management of CVD (and hypertension in particular) in-person or online. Attendees feedback will be sought to improve the curriculum prior to being rolled-out in the next phase of this research project. In parallel, the InterCARE Study Team will work with the 2 clinics Information Technology teams to adapt the existing electronic health records with CVD-specific flags, medication lists and laboratory panels. Finally, up to 288 participants (PLWHIV) and their treatment partners will be enrolled from those 2 clinics patients lists to pilot the overall InterCARE package. The results and experiences from the pilot stage will be assessed and collated to make improvements to each of the 3 intervention in the package. This final set of improved interventions will be the basis of the second phase of the InterCARE research project. Phase 1 was successfully completed in November 2022. 2. The InterCARE package will be tested as a cluster randomised trial in 14 clinics around Botswana: 7 clinics will receive the InterCARE package while the remaining 7 clinics will not received any intervention, continuing with the local standard of care, with a target combined recruitment target of 4652 participants overall, to be followed up for 24 months. Phase 2 is anticipated to take place from January 2023 to July 2025.
Interventions
The InterCARE package includes: 1. Healthcare Provider HTN/CVD Curriculum A new HTN curriculum will be developed in collaboration with local stakeholders using KITSO Master trainer program documents (Healthcare provider HIV curriculum), Primary Care Guidelines, HTN/CVD curriculum/protocols trialled in Kweneng District and the CDC Prevention Hypertension Management Curriculum. 2. Adaptation of HIV care EHR for HTN/CVD care EHR modifications will be done to enhance data collection around HTN/CVD care, with input from MoH. 3. Patient and treatment partner sessions Clinic staff will provide in-clinic education and counselling on HTN/CVD to all PLWHIV with a diagnosis of hypertension during their routine HIV clinic visit. All patients will be provided a take-home easy-to-read pamphlet on HTN/CVD risk factor management. All PLWHIV will be asked to bring a treatment partner from their social network at the 2nd study visit so that they can practice role-plays with each other.

Intervention model description
InterCARE is the name of the package of implementation strategies proposed by the investigators that are intended to integrate cardiovascular care services into existing HIV care systems in Botswana. The InterCARE package includes 3 main interventions: 1. a tailored inter-professional training curriculum on management of CVD risk and HIV 2. adaptation of the existing electronic health records (PIMS) 3. adoption of a treatment partner support system.

Exclusion criteria
