Outline of Final Research Achievements

In this study, we will examine the potential for medical services to be provided by health care facilities to patients who come to the hospital, using M/M/c queueing theory to compare health care delivery capacity for each secondary medical area. As a result, we identified the optimal secondary care area where the variance in utilization of all secondary medical area was minimized. We next studied the optimization of secondary medical areas by patient incidence rate, travel time and hospital type.
Finally, the characteristics of the network that can be found from the simulation analysis of secondary medical areas and the results of individual simulations of secondary medical areas were also verified for their realistic validity.

Academic Significance and Societal Importance of the Research Achievements

本研究は、医療機関による医療サービス提供能力をシミュレーションにより分析することにより、二次医療圏ごとの比較を行ない、最適な二次医療圏を明らかにすることができた。その上で、災害時における患者発生率、移動時間、病院種別を考慮に入れて、災害時における二次医療圏の最適化の分析を試みた。
平常時と災害時の医療圏のあり方について、検討するために一つの知見を得ることができたと考えられる。
