TY - Type of reference TI - PoleSat, health planning modelling for decision support. Application to a reorganization of vascular catheterization provision, at the geographic level of "territorial hospital grouping". AU - Lorraine Trilling AU - Anne Quesnel-Barbet AU - Julien Soula AU - Erik-André Sauleau AU - Pierre Bazile AU - François Dufossez AU - Gilles Maignant AU - Frédéric Albert AU - Arnaud Hansske AB - Three key factors appear relevant in view of annual optimizations of the Public Hospital management: territorial reorganization, quick change in medical technologies and maintaining balanced budgets. Finding the right tools for territorial analysis, making it possible to achieve the efficiency of the care sectors of "territorial hospital groupings" is the priority of the Health Care Directorate, and this is the context in which PoleSat has been evaluated. Method: three scenarios have been considered for ‘vascular catheterizations’ among seven hospital hubs of Nouvelle Aquitaine: the existing situation, the closure of the Rochefort hub and the transfer of activity from Rochefort to the Saintes hub. Different analyzes of "modeled catchment areas and allocations of populations and activities" have been compared. Results: After comparisons of the pre-post scenarios of the covered areas and the concerned statistic of population, consequences and impacts for the hubs are expressed in ‘risks of loss’ and ‘chances of gain’ of activity and patient numbers. Conclusion: Taking into account its first tests and good repeatability, PoleSat is proving to be robust and reliable. It will be enhanced and reused for other care services, geographic spaces and territories.
