| Research Abstract |
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.
