The demand for geographic information systems (GIS) and related tools is increasing among public health decision-makers, as the utility is being recognized and both methodological innovations and computational capacity evolve. Simulation studies of optimal geographical placement scenarios for health services, including community health workers, have been developed to inform programmatic decisions related to the size of catchment areas and to identify where there are coverage gaps and/or priority areas for scale-up.
Due to social and political vulnerabilities, as well as the number of natural disasters that Haiti had to face, the current health system cannot guarantee health service access and quality to the majority of the population. The deployment of polyvalent community health workers (ASCPs), covering population in urban, rural and difficult-to-reach areas is a constitutive part of the person-centred primary care reinforcement initiated by the ministry of health and will accelerate efforts to reach universal health coverage. The primary objective of the placement is to provide universal access for the entire population to a care service within a certain distance.
The AIM group provided support to the Haitian strategic plan on community health by providing scenarios for optimized geographical community health worker placement, accounting for travel time, population density and health facility locations.
