Community health worker training and education
Intervention group:
Programmes that train or educate community health workers (CHWs). CHWs are defined as "paraprofessionals or lay individuals with an in-depth understanding of the community culture and language, have received standardised job-related training of a shorter duration than health professionals, and their primary goal is to provide culturally appropriate health services to the community (Olaniran et al. 2017).”
