Acceptability of a community health worker- led health literacy intervention on lifestyle modification among hypertensive and diabetes patients in the City of Harare, Zimbabwe.

Deploying community health workers (CHWs) is a vital strategy to improve health at a community level in low- and middle-income countries. Whilst there is substantial evidence on the effectiveness of CHWs interventions, there is a need for more research on the mechanisms through which these interventions work. Understanding the acceptability of these interventions is one way of assessing the mechanisms through which they work. This article examines the acceptability of a community health worker- led health literacy intervention on lifestyle modification among hypertensive and diabetes patients based on the perspectives of the CHWs, community nurses and diabetes and hypertensive patients. A qualitative study was imbedded within a cluster randomized trial to assess the effectiveness community health worker- led health literacy intervention on lifestyle modification among hypertensive and diabetes patients in the City of Harare, Zimbabwe. Data were gathered through semi-structured interviews with 3 community health nurses and 15 diabetes and hypertension patients as well as 2 focus group discussions with CHWs. Data were analyzed manually using the thematic analysis method. There was consensus that the intervention had many benefits amongst CHWs and community nurses. However, among patients, there were mixed perceptions regarding the benefits of the intervention. The main challenges that were mentioned by CHWs include resistance to advice by patients, insufficient resources, and lack of acceptance at some of the patient's homes. All participants believed the intervention was acceptable. Our study provides vital information that should be considered in upscaling CHW led interventions.
