RESUMO
Current care models are inadequate to address the dual epidemic of hypertension and HIV in sub-Saharan Africa. We developed a community health worker (CHW)-delivered educational intervention, integrated into existing HIV care to address hypertension in persons living with HIV. A detailed educational curriculum was created with five sessions: three in-person clinic sessions and two telephone sessions. The intervention was piloted among hypertensive adults at one HIV clinic in northern Tanzania over a 4-week period. Primary outcomes were feasibility, fidelity, and acceptability of the intervention. Secondary outcomes included hypertension care engagement and systolic and diastolic blood pressure (SBP and DBP). Among 16 eligible participants, 14 (64% women, median age of 54.5 years) were recruited into the study, and 13 (92.9%) completed all five intervention sessions. The intervention was delivered with 98.8% fidelity to the curriculum content. Hypertension care engagement improved following the intervention. At baseline, two (15.4%) participants had seen a doctor previously for hypertension, compared to 11 (84.6%) participants post-intervention (P = .0027). No participant was using antihypertensives at baseline, compared to 10 (76.9%) post-intervention (P = .0016). Pre-intervention median SBP was 164 (IQR 152-170) mmHg, compared to post-intervention SBP of 146 (IQR 134-154) mmHg (P = .0029). Pre-intervention median DBP was 102 (IQR 86-109) mmHg, compared to post-intervention DBP of 89 (IQR 86-98) mmHg (P = .0023). A CHW-delivered educational intervention, integrated into existing HIV care, is feasible and holds promise in improving hypertension care engagement and reducing blood pressure. Further research is needed to evaluate the efficacy and scale-up of our intervention.
