Assessment of hypertension service availability in some primary health centres in Nigeria: a mixed-methods study

OBJECTIVE: Strengthening primary health centre (PHC) systems is a potentially effective strategy to reduce the burden of non-communicable diseases in Nigeria, a low/middle-income country with limited resources. The aim of this study was to assess hypertension service availability in some PHCs in Nigeria and seek recommendations that could facilitate improved services from PHC workers. DESIGN: Explanatory sequential mixed-methods study. SETTINGS: PHCs in the six geopolitical zones and Federal Capital City of Nigeria. PARTICIPANTS: Eighteen PHC workers and 305 PHC facilities. METHOD: Hypertension service availability and readiness were assessed in PHCs across Nigeria using a pro forma adapted from the WHO Service Readiness and Assessment tool. Eighteen workers in the PHCs were subsequently interviewed for in-depth exploration of hypertension service availability and readiness. FINDINGS: Among the 305 health facilities assessed, 96 (31.5%) were in urban, 94 (30.8%) in semiurban and 115 (37.7%) in rural local government areas. Majority of the health facilities (43.0%) were manned by community extension workers. Only 1.6% and 19.7% of the health facilities had physicians and pharmacy technicians, respectively. About 22.3% of the providers had training in hypertension in the last 1 year. All the PHCs lacked adequate supply of essential antihypertensive medications. The identified deficiencies were less common in the urban PHCs compared with others. Qualitative analysis showed that the personnel, essential facilities and medicines required to provide hypertension services in the PHCs were inadequate. Suggested recommendations to successfully provide these services were provision of performance-based incentives; adequate staffing and training; supportive supervision of staff; provision of adequate equipment and essential medicines for hypertension management; provision of conducive environment for clients; and community engagement and participation. CONCLUSION: Majority of the PHCs are currently not adequately equipped to provide hypertension services. Addressing identified gaps and using suggestions provided will guarantee successful provision of effective services.
