Abstract
Community health workers (CHWs) are integrated into health systems through a variety of designs. Partners In Health (PIH), a nongovernmental organization with more than 30 years of experience in over 10 countries, initially followed a vertical approach by assigning CHWs to individual patients with specific conditions, such as HIV, multidrug resistant-TB, diabetes, and other noncommunicable diseases, to provide one-on-one psychosocial and treatment support. Starting in 2015, PIH-Malawi redesigned their CHW assignments to focus on entire households, thereby offering the opportunity to address a wider variety of conditions in any age group, all with a focus on working toward effective universal health coverage. Inspired by this example, PIH-Liberia and then PIH-Mexico engaged in a robust cross-site dialogue on how to adapt these plans for their unique nongovernmental organization-led CHW programs. We describe the structure of this "household model," how these structures were changed to adapt to different country contexts, and early impressions on the effects of these adaptations. Overall, the household model is proving to be a feasible and functional method for organizing CHW programs so that they can contribute toward achieving universal health coverage, but there is no "one-size-fits-all" approach. Other countries planning on adopting this model should plan to analyze and adapt as needed.
