社会的指標を用いたドクターヘリコプターシステム普及のための要因分析

Abstract

Medical helicopter systems have been in place in Japan from 2001. However, there are only 12 systems operating in 2007. The high cost has been pointed out as the greatest problem for the spread of medical helicopter systems. There have not been any previous studies undertaken about the social factors such as finance, population and so on. This study aim to clarify the relationship between the regional social factors of places where medical helicopter systems do or do not exist. We will apply a logistic-regression analysis and a principal component analysis. As a result of study, the financial coefficient is an important factor for the spread. In addition, 47 prefectures of Japan have been classified into three groups by the regional social factors. We propose co-operative management between neighbor prefectures for systems to spread. Then, the efficient and economical management of medical helicopter systems can be realized.
