A cluster-randomized trial of task shifting and blood pressure control in Ghana: study protocol
Background Countries in sub-Saharan Africa ( SSA ) are experiencing an epidemic of cardiovascular disease ( CVD ) propelled by rapidly increasing rates of hypertension . Barriers to hypertension control in SSA include poor access to care and high out-of-pocket costs . Although SSA bears 24 % of the global disease burden , it has only 3 % of the global health workforce . Given such limited re sources , cost-effective strategies , such as task shifting , are needed to mitigate the rising CVD epidemic in SSA . Ghana , a country in SSA with an established community health worker program integrated within a national health insurance scheme provides an ideal platform to evaluate implementation of the World Health Organization ( WHO ) task-shifting strategy . This study will evaluate the comparative effectiveness of the implementation of the WHO Package targeted at CV risk assessment versus provision of health insurance coverage , on blood pressure ( BP ) reduction . Methods Using a cluster r and omized design , 32 community health centers ( CHCs ) and district hospitals in Ghana will be r and omized to either the  intervention  group ( 16 CHCs ) or the control group ( 16 CHCs ) . A total of 640 patients with uncomplicated hypertension ( BP 140–179/90–99 mm Hg and absence of target organ damage ) will be enrolled in this study ( 20 patients per CHC ) . The intervention consists of WHO Package of CV risk assessment , patient education , initiation and titration of antihypertensive medications , behavioral counseling on lifestyle behaviors , and medication adherence every three months for 12 months . The primary outcome is the mean change in systolic BP from baseline to 12 months . The secondary outcomes are rates of BP control at 12 months ; levels of physical activity , percent change in weight , and dietary intake of fruits and vegetables at 12 months ; and sustainability of intervention effects at 24 months . All outcomes will be assessed at baseline , six months and 12 months . Trained community health nurses will deliver the intervention as part of Ghana ’s community-based health planning and services ( CHPS ) program . Discussion Findings from this study will provide policy makers and other stakeholders needed information to recommend scalable and cost-effective policy with respect to comprehensive CV risk reduction and hypertension control in re source -poor setting s .
