Cost and cost-effectiveness analysis of Public Access Automated External Defibrillators

日本部署的公共通道自动体外除颤器(AEDs)的数量有所增加，但很少有研究分析AEDs在国家和县一级的成本效益。利用日本全国数据库中的数据，估算了2005至2010年间各县的抗癫痫药物的成本效益。用增量成本和效果计算AEDs的增量成本效果比(ICER)。扣除折扣后，ICER为9,455,000日元。各县之间的ICER从555.5万日元到45505000日元不等。本研究表明，各县在AEDs的总成本、效果和成本-效果方面存在较大差异。考虑到AEDs的适当部署，在国家和地方两级分析AEDs的成本效益可能很重要。

The number of public access automated external defibrillators (AEDs) deployed has increased in Japan but few studies have analyzed the cost-effectiveness of AEDs at national level as well as at prefectural level. The cost-effectiveness of AEDs by prefecture was estimated between 2005 and 2010 using data from a nationwide database in Japan. The incremental cost-effectiveness ratio (ICER) of AEDs was calculated using incremental cost and effectiveness. The ICER was calculated at JPY 9,455 thousand with a discount. The ICER differed between prefectures from JPY 5,555 thousand to JPY 45,505 thousand. The present study suggested that there is large difference between prefectures as for the total cost, effectiveness and the cost-effectiveness of AEDs. Analyzing the cost-effectiveness of AEDs at a national and local level could be important considering the appropriate deployment of AEDs.
