Estimation of economic effectiveness for Disease Management and preventative medicine through anticipatory investment

我们根据卫生账户体系（SHA）估算了2005 - 2007财政年度日本的卫生总支出。卫生总支出从2004财政年度的331，110亿日元增加到2005财政年度的331，290亿日元，国家卫生保健支出占80%-82%。通过估算，我们可以提高卫生总费用的国际可比性，并提供有助于评估卫生政策的统计数据。希望能继续进行这方面的研究，以供医疗卫生改革时参考。我们讨论了医疗保健与预防之间的实证研究的结果，以及它的问题。《公共卫生学》是对卫生保健研究的重大贡献，其政策评价主要关注医疗与预防的可替代性。另一方面，经济学主要是计量经济学研究，建立了医疗和预防两个行为模型，然后对其政策进行评价，通过医疗和预防两个行为模型来评价和挑选适合疾病管理的疾病。预期性投资可以通过预防性行为来控制医疗费用，提高医疗质量。公共卫生学与经济学在方法和政策思路上有很大的不同。在完成复杂的政策评估时，需要在这一领域进行进一步的研究。

We estimated the total health expenditure of Japan in accordance with System of Health Accounts (SHA) between fiscal year 2005 and 2007. The total health expenditure increased form 33,111 billion yen in fiscal year 2004 to 33,129 billion yen in fiscal year 2005, and the national healthcare expenditure accounted it for 80%-82%. Through the estimation, we are able to improve the international comparability of total health expenditure, and to provide the statistics which were helpful to assess the healthcare policy. It is hoped that research about this be continued to consider the health care reform which bases the multiphase analysis over the health expenditure. We discussed the results of empirical research between medical care and prevention, and its problems. Public Health, the great contribution to health care research, evaluate its policy concerning about the substitutability between medical care and prevention. On the other hand, Economics, mainly econometrics research, set two behavior models on medical care and prevention, afterwards evaluate its policy.We evaluated and picked up the appropriate diseases for disease management through behavior models on medical care and prevention. An anticipatory investment could curb medical expenses and improve the quality of health care through the preventive behavior.There is a great difference in method and policy thought between Public Health and Economics. In accomplishing sophisticated policy evaluation, needs of further research is in this area.
