In the aim to answer to our problematic and hypothesis on the spatial utilization of the health establishments and services by inpatients and/or by the potential clients, we elaborated a modeling process of catchment areas by medico-surgery specialty applied in the French Nord – Pas-deCalais region. Our gravitation modeling, heart of the research work, assesses the health care demand and supply in our region. This K-means model calculates the theoretical hospital catchment areas by specialty in hematology and traumato-orthopedy which would be those that we could observed if the catchment area was equivalent to this mathematical model. It could be automated and generalized for all specialties and geographic areas. We present in this way the four steps of the modeling process, its results, the discussion and the future research ways. The first phase observes the hospital catchment areas with quantitative and mapping tools. The second is an elaboration of our spatial mathematical model regarding the gravitation Newton law through the refined Reilly’s equation based on the census population of the proximity catchment area. It is calculated from the observed and theoretical hospital attractions. The third phase is a validation of our model by comparison between the observed and the theoretical models with the help of observed maps, models drawings and quantitative methods (coefficients of attraction). The last predicts and simulates “the creation or the closing” of hospital services by specialty. Through the results this model appears to be robust, reliable and ’predictive’ in spite of its simplicity (two parameters are used : numbers of beds and the census populations). Consequently, our model, along with a better knowing of the spatial utilization of health services, can be a new tool for developments in health facility planning at health care districts.
