Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Control
All clusters will be observed under both the intervention and control arm through sequential crossover.
|
|
Experimental: Community health worker delivered multicomponent intervention
The study will employ a closed cohort stepped wedge cluster randomized design.
There will be a sequential crossover of clusters from the control to the intervention arms and the order of the cross over will be randomly determined.
This study will be conducted in 21 clusters within Nakaseke district.
Each cluster will consist of 4-5 villages.
We plan to rollout the intervention in three clusters per month.
|
The multi-component intervention will be centered on monthly household visits by trained CHWs for a period of seven months in a rural setting in Nakaseke, Uganda, consisting of the following; (1) blood pressure and sugar monitoring; (2) BMI monitoring; (3) cardiovascular disease risk assessment; (4) Using checklists to guide monitoring and referral to clinics; (5) healthy lifestyle counselling and education. During home visits, CHWs will remind patients of follow-up visits. We will measure blood pressure at baseline and 3-monthly for the entire cohort. We will conduct individual-level mixed effects analyses of study data, adjusting for time and clustering by patient and community. We will conduct an interim analysis at 3 months to assess differences between groups. If a statistically significant difference is detected the intervention will be applied across the remaining clusters |
