Abstract
Community Health Worker (CHW) interventions have shown potential to reduce inequities for underserved populations. However, there is a lack of support for CHW integration in the delivery of health care. This may be of particular importance in rural areas in the Unites States where access to care remains problematic. This review aims to describe CHW interventions and their outcomes in rural populations in the US. Peer reviewed literature was searched in PubMed and PsycINFO for articles published in English from 2015 to February 2021. Title and abstract screening was performed followed by full text screening. Quality of the included studies was assessed using the Downs and Black score. A total of 26 studies met inclusion criteria. The largest proportion were pre-post program evaluation or cohort studies (46.2%). Many described CHW training (69%). Almost a third (30%) indicated the CHW was integrated within the health care team. Interventions aimed to provide health education (46%), links to community resources (27%), or both (27%). Chronic conditions were the concern for most interventions (38.5%) followed by women’s health (34.6%). Nearly all studies reported positive improvement in measured outcomes. In addition, studies examining cost reported positive return on investment. This review offers a broad overview of CHW interventions in rural settings in the United States. It provides evidence that CHW can improve access to care in rural settings and may represent a cost-effective investment for the healthcare system.
