 The national deployment of polyvalent community health workers, CHWs, is a key component of the Haitian government's strategy to achieve universal health coverage. To optimize this process, mathematical models were used to identify potential CHW locations and determine how many CHWs should be deployed in order to maximize access to care. The models considered population density, travel times, and the proximity of existing health centers when determining optimal CHW placements. The results showed that there was a lack of CHWs in certain regions and that some areas had limited access to care due to the current CHW distribution. This suggests that more CHWs should be deployed in those areas in order to improve access to care. This article was authored by Clara Champagne, Andersoniel Rajkumar, Paul Oxsala, and others.
