Brief Summary:
Uptake of a community-based evidence-supported interventions for hypertension control in Ghana are urgently needed to address the cardiovascular disease epidemic and resulting illness, deaths, and societal costs. This study will evaluate the effect of Practice Facilitation on the uptake and maintenance of the evidence-based task-shifting strategies for hypertension control (TASSH) protocol across 70 Community-based Health Planning and Services (CHPS) zones delivered by trained community health officers.
Findings from this study will provide policy makers and other stakeholders the "how to do it" empirical literature on the uptake of evidence-based interventions in Ghana, which may be applicable to other low-income countries.
Detailed Description:
Ghana and other countries in sub-Saharan Africa (SSA) are experiencing an epidemic of cardiovascular diseases (CVD) propelled by rapidly increasing rates of hypertension requiring implementation of evidence-based interventions. However, persistent barriers to the uptake of evidence-based interventions in low resource settings including Ghana exist at the systems, organizational and provider levels. At the systems level, lack of leadership support and shortage of staff limit effective uptake of evidence-based hypertension interventions. At the organizational level, the organizational culture, particularly the organization's readiness or openness to change may influence the use of evidence-based hypertension interventions. At the provider-level, implementation climate, lack of training, the culture of individual practices, and provider's knowledge, self-efficacy and attitude towards the evidence-based intervention limits uptake and sustainability of evidence-based interventions. The ubiquity of CHPS zones in Ghana, and their growing involvement with implementing healthcare in every community, with outreach to every doorstep, presents a unique opportunity to evaluate the effectiveness and impact of scaling up evidence-based task-shifting strategies for hypertension (TASSH) control for adults in community settings. Using a mixed methods (quantitative-qualitative) design, the investigators will evaluate practice facilitation (PF) in 70 CHPS compounds utilizing the TASSH program.
The specific aims are as follows: (1) to identify practice capacity for the adoption of TASSH at CHPS compounds and develop a culturally tailored PF strategy using qualitative methods; (2a) Evaluate in a stepped-wedge cluster Randomized Controlled trial (RCT), the effect of the PF strategy vs. Usual Care (UC), on the uptake of TASSH (primary outcome) across the CHPS compounds at 12 months;(2b) Compare in a stepped-wedge cluster RCT, the clinical effectiveness of the PF strategy vs. UC on systolic BP reduction (secondary outcome) among adults with uncontrolled hypertension at 12 months; (3) Evaluate the mediators of the uptake of TASSH across the CHPS zones at 12 months; and (4) Evaluate the sustainability of TASSH implementation across the participating CHPS compounds at 24 months (one year after completion of the trial). Outcomes will be measured every 12 months in all clusters. Guided by Damshroeder's Consolidated Framework for Implementation Research (CFIR) and Glasgow's Reach Effectiveness Adoption Implementation and Maintenance (RE-AIM) framework, the goal of this project is to improve the uptake of evidence-based task-shifting strategies for hypertension control (TASSH) in CHPS zones in Ghana. This proposal is a collaboration between the Kwame Nkrumah University of Science and Technology, Kintampo Health Research Center, New York University (NYU) School of Medicine and Saint Louis University.
