Modeling Physical Accessibility to Health Care and Geographic Coverage (AccessMod©)

How does AccessMod© work?

AccessMod© uses the functions of Esri’s GIS technology to apply a specific set of algorithms on a series of GIS layers containing the information influencing the time taken by a patient to reach the nearest health facility depending on the mode of travel (for example, by feet, by car, etc).

Analysis of an existing health facility network is then done through the generation of the catchment areas attached to each facility and the determination of the population living within each of these catchment areas. This analysis can be done for in-patients and out-patients and can include different type of facilities simultaneously.

AccessMod© also assists in determining the location for new health facilities when scaling up the existing network. This function can be applied for in-patients or out-patients when dealing with only one type of facility at a time. At present this function can be applied to only out-patients based systems if there is need to compare several types of facilities simultaneously.

For more information on the functions of AccessMod©, please refer to the user manual or the list of publications reported in the following pages.
