Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

For the first 12-month of the study, the intervention will not be implemented as this is a stepped-wedged design. During this time period, primary outcome (adoption ratings) and secondary outcome (Systolic BP) data will be collected at the CHPS Zones following TASSH training and the PFOs will provide support to their assigned CHPS zones to prepare to implement the TASSH protocol.

Each CHPS zones will then be randomly assigned to one of the two intervention arms: Group A will receive the Practice Facilitation Strategy at 12 months and Group B will initially serve as a Usual Care comparison group. Group B will then receive Practice Facilitation beginning 24 months into the trial, as this is a stepped wedge design. Sustainability for groups A and B will be assessed one year after the end of the intervention.

Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Practice Facilitation Group A

After the first 12 months of usual care (No Practice Facilitation), group A will begin to receive the Practice Facilitation (PF) Strategy at the CHPS compounds in addition to Ghana's National Health insurance and the World Health Organization (WHO) CVD Risk Assessment package.

Group Type EXPERIMENTAL

Practice Facilitation

Intervention Type OTHER

Community health nurses trained in implementing the evidence-based TASSH protocol will be employed as Practice Outreach Facilitators (POF) to train the CHPS community health officers to deliver TASSH. The POFs will be required to complete an intensive 12-week training course focused on adoption of TASSH protocol to identify patients at risk for uncontrolled HTN, initiate behavioral lifestyle counseling, and Refer patients to the community health centers for drug therapy. Over the course of 12 months, the POFs will provide support to their assigned CHPS zones to implement TASSH as part of routine patient care.The POFs will also work with CHPS directors to review current work flow and develop a plan of action for TASSH uptake at the CHPS zones.

Usual Care

Intervention Type OTHER

Provide Ghana's National Health Insurance, behavioral counseling and referral for care through the usual care system for 12 months.

Practice Facilitation Group B

Group B will receive Usual Care (no PF) between 12-24 months which includes Ghana's National Health Insurance, behavioral counseling and referral to care through the usual care system.

After 24 months into the trial, Group B will then receive Practice Facilitation strategy in addition to Ghana's National Health insurance and the World Health Organization (WHO) CVD Risk Assessment package for a duration of another 12 months, as this is a stepped wedge design.

During this 12 months period, practice facilitation will end in the Group A arm.

Group Type EXPERIMENTAL
