Study on theory establishment of National Health Insurance Listing in which willingness to pay is adjusted to budget

关于医疗保险制度的支付意愿（WTP;基于合作精神的他人的生命拯救、随机效应模型和联合分析）的研究结果为674个样本中的3，272（千日元/Qaly）（回答率24.2%）。至于“治疗负荷”属性对预期效用值的影响，各项要求在统计学上皆有显著性差异。例如，在“持续时间;短，负担;低”中，标准化系数为0.570（p<0.001）。作为ESRD维持性血液透析滤过（HD）的调查结果，认为其成本效益为40，000 - 60，000（US$/Qaly）。我们通过蒙特卡罗模拟方法建模，根据患者数量和增益效用以及每QALY的支付意愿计算HD总受益。因此，如果将劳动一代的支付意向限定为劳动一代，则分析的平均值为152.03万（百万日元/年，2011年估计）。这一结果比当年实际公共医疗费用高出611亿日元。

The result of this research of willingness to pay (WTP; lifesaving of the others on spirit of cooperation, random effect model and conjoint analysis) about the medical insurance system became 3,272 (thousand JPY/Qaly) in 674 sample (answer rate 24.2%). As for the influence that the attribute of "therapy load" exerted on the expected utility value, all requirements were significant in statistics. For instance, the standardization coefficient is 0.570(p<0.001) in "duration; short, burden; low". As a result of the survey of the maintenance hemodiafiltration (HD) of ESRD, the cost-effectiveness was thought to be 40,000 - 60,000 (US$/Qaly). We calculated the total of HD benefit according to patient number and gain utility and WTP per QALY with the modeling by the Monte Carlo simulation method. As a result, the average of analysis is 1,520,300 (million JPY/year, estimate in 2011) when limiting it to the working generation of the payment intention of the working generation. This result is 61.1 (billion JPY) more than actual public medical expense during year.
