A method is presented that has numerous applications to health systems provision in developing countries where limited physical access to primary health care is a major factor contributing to the poor health of populations. An accessibility model within a geographical information system (GIS) is used to predict average inter-homestead walking times and subdivide the study area into units of equal completion time. The method could be used to ergonomically design home-based care and tuberculosis directly observed treatment programmes and inform the siting of health facilities. The paper highlights the use of GIS technology as a powerful tool in developing countries.
