General Objective :
To evaluate the effectiveness and implementation of a program called BECOME on depression
and/or anxiety, and two NCDs using a stepped-wedge cluster randomized trial (SWCRT) and
the RE-AIM framework.
Specific Objective :
Assess the effectiveness of BECOME on depression and anxiety, and two NCDs (diabetes
and hypertension) via a stepped-wedge cluster randomized trial.
Assess implementation outcomes of BECOME using the RE-AIM framework at the patient,
provider, and health system levels
Conduct a comprehensive costing analysis to provide strategic inputs to support
long-term scale up of BECOME.
Study Variables Dependent variable; Primary outcome: depression and anxiety severity,
Secondary outcome: Diabetes (as measured by fasting plasma glucose) and hypertension (as
measured by systolic and diastolic blood pressure) Independent variable; Demographics
(for example, age, sex) Stress, Isolation and withdrawal, Quality of Life, Tobacco Use,
Diet Quality, Physical activity, Medication and follow up adherence, Environmental
factors- access to care (community-based and higher intensity clinical care), social
support, life style.
Research Method : mixed
Study sites : Bardibas and Chandragiri municipalities, Nepal
Specify type of Study This study is a type-II hybrid effectiveness- implementation study.
The study will use a stepped-wedge randomized controlled trial design.
Study Population
Patient Participants: Individuals who are 40 years or above residing in Chandragiri and
Bardibas Municipalities who have at least one NCD (hypertension and/or diabetes) and one
Mental Health (depression and/or anxiety), and who give consent for the study
participation.
Community health workers: Community health workers who are working in Chandragiri and
Bardibas municipalities under the government pilot program following community health
program guidelines 2078 endorsed by the Ministry of Health and Population. They are the
community health nurses employed by municipalities. They are the trusted local member of
the community who are trained and regularly supported and monitored by their supervisors.
They work full-time and get a monthly salary for their service/work.
Primary care providers and health system leaders: who are working either in the health
facilities of Chandragiri and Bardibas municipalities, municipal health office, and
relevant stakeholders who are contributing to the community health program in different
capacities.
Sampling unit
Since this is a stepped wedge cluster randomized controlled trial, we will use the
cluster as our sampling unit while implementing the study.
Sample size
631 Participants; 20 CHWs; 5 Primary care providers; 6 Health system leaders
Description of study design:
The is a type-II hybrid effectiveness-implementation study design. The goal of the
effectiveness aim is to evaluate the impact of the BECOME intervention against usual care
while the implementation aim focuses on understanding the process of implementing the
intervention in a real-world setting. Additionally, the study will conduct a
comprehensive costing analysis to provide strategic inputs to support the long-term
scale-up of BECOME.
The study will use a stepped-wedge cluster randomized controlled trial design. In this
design, 20 clusters (wards) will be randomly assigned to one of five steps, with all
clusters starting in the control phase prior to receiving the intervention. Every three
months, four clusters will transition to the intervention condition, while the remaining
clusters will remain in the control condition. This design allows for a gradual rollout
of the intervention, which can help minimize the impact of any learning curves or
logistical challenges that may arise during implementation.
The study will use an open cohort design, which means that enrollment will be kept open
while the intervention is being offered. This approach helps to reflect real-world
conditions and can compensate for attrition and for participants who may no longer meet
the eligibility criteria when their cluster transitions to the treatment phase. By using
this design, the study can capture the dynamic nature of the intervention and better
understand its impact over time.
Overall, this study aims to evaluate the effectiveness and implementation of the BECOME
intervention, as well as provide insights into the costs associated with implementing the
intervention in a real-world setting. By using a stepped-wedge cluster randomized
controlled trial design and an open cohort design, the study can capture a comprehensive
picture of the intervention's impact and implementation process.
