Managing Hypertension in Rural Gambia and Kenya: Protocol for a Qualitative Study Exploring the Experiences of Patients, Health Care Workers, and Decision-makers

Background: Hypertension is the single leading risk factor for premature death in Sub-Saharan Africa (SSA). Prevalence is high, but awareness, treatment, and control are low. Community-centred interventions show promise for effective hypertension management, but embedding such interventions sustainably requires a good understanding of the wider context within which they are being introduced. This study aims to conduct a systematic health system assessment exploring the micro (patients/carers), meso (health care workers and facilities), and macro (broader system) contexts in rural Gambia and Kenya.

Methods: This study will utilise various qualitative approaches. We will conduct (i) focus group discussions with people living with hypertensive to map a 'typical' patient journey through health systems, and (ii) in-depth interviews with patients and family carers, health care workers, decision-makers, and NCD partners to explore their experiences of managing hypertension and assess the capacity and readiness of the health systems to strengthen hypertension management. We will also review national guidelines and policy documents to map the organisation of services and guidance on hypertension management. We will use thematic analysis to analyse data, guided by the cumulative complexity model, and theories of organisational readiness and dissemination of innovations.

Expected Findings: This study will describe the current context for the management of hypertension from the perspective of those involved in seeking (patients), delivering (health care workers) and overseeing (decision-makers) health services in rural Gambia and Kenya. It will juxtapose what should be happening according to health system guidance and what is happening in practice, drawing on the experiences of study participants. It will outline the various barriers to and facilitators of hypertension management, as perceived by patients, providers, and decision-makers, and the conditions that would need to be in place for effective and sustainable implementation of a community-centred intervention to improve the management of hypertension in rural settings.
