Abstract P563: Exploring Facility and Patient-Level Determinants of Changes in Systolic Blood Pressure Among Patients With Hypertension: A Multicenter Study in Ghana

Abstract

Background: Optimal blood pressure control is essential in averting complications and associated cardiovascular risks. Although a 5-mmHg reduction in systolic blood pressure (SBP) is associated with better health outcomes, individual-level and health facility dynamics might influence optimal blood pressure control. We explored individual and health facility-level factors of SBP changes among patients with hypertension in Ghana. Methods: We recruited 15 health facilities that provided hypertension care and from each facility, 15 patients who were currently receiving hypertension care during their clinic appointment. We explored patient-level (adherence to treatment, length of time with hypertension diagnosis, and sociodemographic factors) and health-facility level (accessibility of care, health facility management, bed capacity, provider training, and provider-patient ratio) predictors. We fitted two-level mixed-effect linear regression models to identify predictors of SBP changes. Results: We included 222 patients, 81% were female, and 48% had achieved blood pressure control of < 140/90 mmHg. At the patient level, secondary-level education was associated with a 7.5 mmHg (95% CI: -14.74, -0.28) greater reduction in SBP than a primary or lower level of education (Table). Patients treated at private facilities had on average 15.8 mmHg (95% CI: 4.97, 26.62) higher SBP than those in government health facilities. Patients who were receiving care at health facilities where a physician or physician assistant treated ≥ 280 patients/month had 28.4 mmHg (95% CI: 9.77, 46.97) higher SBP than those receiving care from a physician/physician assistant who cared for < 140 patients/month. Conclusion: Health system interventions to address individual barriers, the shortage of healthcare providers, and team-based care strategies are needed to address the burden of hypertension in Ghana.
