title: Radiotherapy service delivery models for a dispersed patient population.
abstract: Access to health care interventions can be impeded when significant patient travel is required. In this economic evaluation we compare, from a societal perspective, three scenarios for the delivery of radiation treatment to an idealized population of 1,600 patients distributed between two urban nodes (1,200 + 400 patients each) separated by up to 500 km. As it is implicitly assumed that the clinical outcome for those patients who access the system is independent of the service delivery model, this study constitutes a cost minimization analysis from a societal perspective. The costs to the health care system are based on an activity costing model developed by us and consistent with recent Canadian studies. The costs to the patient are approximated by a formula that includes direct costs (travel and accommodation) and indirect (time) costs, with the latter based on a human capital approach. A sensitivity analysis has been performed to confirm the robustness of our conclusions both to uncertainties in the input data and to the inclusion of time costs, the estimation of which remains controversial. From a societal cost perspective only, we show that outreach radiotherapy (central comprehensive facility and satellite) is the economically superior service delivery model for separations between 30 km and 170 km. Beyond 170 km, a fully decentralized service would be warranted if the only consideration were societal economic advantage.
