Scaling Up Community-based Noncommunicable Disease Research into Practice in Pokhara Metropolitan City of Nepal (SCALE-NCD)

Background

Rapid globalization and urbanization continue to escalate the burden of non-communicable diseases (NCDs) across the world, disproportionally affecting low- and middle-income countries (LMICs). Nepal is one of the fastest urbanizing LMICs where the NCD burden has skyrocketed. In Nepal, control of the major three NCD risk factors – high blood pressure (BP), high blood glucose (BG) and smoking—are dismally low, particularly in urban areas, due to multiple levels of adverse health determinants. One reason for poor control is a dearth of physician and nurses. Community health workers (CHWs) can fill this void. To date, trials have documented that task-sharing with CHWs reduces systolic BP and fasting BG and achieves smoking cessation. However, most trials have been done in rural areas, and most trials of CHWs tested management of a single condition, e.g. just hypertension. Furthermore, despite demonstrated impact in systematic reviews, task-sharing with CHWs is far from being fully implemented in health care delivery systems in LMICs, including Nepal. In this context, we propose to conduct the first implementation research study on task-sharing with CHWs for concurrent management of hypertension, diabetes, and smoking in an urban, LMIC setting.

Aims

Our overarching goal is to scale up our demonstrated evidence-based task-sharing interventions to address three NCD risk factors in which we engage key stakeholders and partners, and use contemporary mobile health (m-health) tools.

Project plan

This study, a type 2 hybrid effectiveness-implementation research study, will be conducted in 33 study sites in Pokhara, the second largest city in Nepal. Building upon our teams’ three CHW-led, home- based interventions that significantly reduced BP and fasting BG, and improved smoking cessation rate in semi-urban areas in Nepal as well as an m-health intervention that lowered systolic BP in an urban area in Nepal, we will develop the intervention package named SCALE- NCD.

Our specific aims are

1. Establish a partnership with stakeholders in Pokhara in order to institutionalize and sustain the intervention,

2. Understand equity, determinants, and structured barriers for scale-up of the intervention, and

3. Determine the effectiveness of the SCALE-NCD intervention, and its impact on reach, adoption, fidelity, sustainability, and cost.

This study will be led by exceptionally strong team of implementation scientists, epidemiologists, clinicians, and anthropologists in the field of NCDs who have built trusted relationship with stakeholders in Nepal over time, including policy makers, implementors, advocates, health professionals, CHWs, and patients with NCDs. Greater understanding of “how” the intervention can be scaled up will inform key steps for implementation of task-sharing with CHWs in health care delivery systems in LMICs.
