This team has shown that chamas can be tailored to increase the uptake of health services in pregnancy and infancy, sustain themselves beyond the period of funding and become integrated within a county's health strategy. However, further investment is warranted to validate this intervention in a new region to ensure the positive effects on MNCH are a result of chamas and can be replicated. The purpose of this study is to demonstrate that chamas are an effective service-delivery platform for improving women's and children's health and well-being in western Kenya.
