Study Description

Brief Summary:

This protocol concerns the implementation and evaluation of an intervention designed to realign the existing cadre of Community Health Workers (CHW) in Neno District, Malawi to better support the care needs of the clients they serve. The proposed intervention is a 'Household Model' where CHWs will be assigned to households, rather than HIV or TB specific patients, and will be trained to provide support for a wider range of conditions including HIV, hypertension, diabetes, and pediatric malnutrition. The new model is designed to improve retention in care for clients with chronic, non-communicable diseases, along with increased uptake of women's health services and treatment for pediatric malnutrition, while sustaining the high retention rates for clients in the HIV program. Eleven sites (health centres and hospitals) were arranged into six clusters by estimated size of the catchment area populations, with a population range of 11,680 to 26,260 and an average population of 20,400. The order in which the intervention will be rolled out across the sites will be randomized so that the intervention can be evaluated in a stepped-wedge cluster randomized controlled trial. These clusters were grouped based mostly on geographic location but also on catchment area sizes, in order to maximize feasibility of training for the CHW team and not overload CHW training sessions with too many trainees.
