Implementation of the Liberia National Community Health Assistant (NCHA) Program and Under-five Mortality: A study protocol

Abstract

AbstractIntroductionBetween 2018 and 2022 the Liberian Government implemented the National Community Health Assistant (NCHA) program to improve provision of maternal and child health care to underserved rural areas of the country. Whereas the contributions of this and similar community health worker (CHW) based healthcare programs have been associated with improved process measures, the impact of a governmental CHW program at scale on child mortality has not been fully established.Methods/DesignWe will conduct a cluster sampled, community-based survey with landmark event calendars to retrospectively assess child births and deaths among all children born to women in the Grand Bassa District of Liberia. We will use a mixed effects discrete survival model, taking advantage of the staggered program implementation in Grand Bassa districts over a period of 4 years to compare rates of under-5 child mortality between the pre- and post-NCHA program implementation periods.DiscussionThis study will be the first to estimate the impact of the Liberian NCHA program on under-5 mortality.Trial registrationclinicaltrials.govNCT:NCT05123378
