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

在日本，公众使用的自动体外除颤器（AED）的数量有所增加，但很少有研究分析AED在国家一级和县一级的成本效益。2005年至2010年期间，使用日本全国数据库的数据估计了各都道府县AED的成本效益。采用增量成本-效果法计算AED的增量成本-效果比（ICER）。ICER计算为9，455，000日元，有折扣。ICER在都道府县之间的差异从5，555，000日元到45，505，000日元不等。本研究结果表明，不同地市间AED的总费用、有效性和成本-效果存在较大差异。考虑到AED的适当部署，在国家和地方一级分析AED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.
