An hierarchical location-allocation model for primary health care delivery in a developing area.
Location-allocation models can play an important role in making primary health care facilities more accessible to rural populations in the developing world. Traditional models, however, have failed to deal realistically with the fact that health care systems are hierarchical in nature, and that benefits and utilization decline with distance. In this paper, an hierarchical location-allocation model in which benefits accrue to facility level and decline exponentially with distance is presented as a possible approach to ameliorating problems of rural accessibility to health care in Third World settings. The model is subjected to sensitivity analysis with reference to data for Salcette Taluka, Goa, India. The analysis suggests that the traditional P-median model may be a much less appropriate solution to the problem than a simple strategy of locating facilities from the highest to the lowest level in centers of strictly decreasing population.
