基于标准博弈法的牙齿健康效用值及意愿支付值OA

Objective To assess the dental health utility value and the monetary value of each quality adjusted tooth years(QATYs)in the Chinese population,and to provide a basis for the economic evaluation of oral health interventions based on the Chinese population.Methods Conducting a face-to-face survey within the main urban area of Harbin,the utility values of four types of dental health states(molar caries with pain,molar caries without pain,molar caries still needing further restoration after restoration,molar caries rehabilitated after filling treatment)were evaluated by using standard game theory.In this paper,we used the commonly used declarative preference measurement method,which combined the open-ended guidance technique with the standard game method to measure the situation of four supposed dental health states in the quality-adjusted dental measurement,respondents were asked to move from the four assumed dental health states to the amount they would be willing to pay in a lump sum for"Perfect dental health".Results A total of 230 questionnaires were distributed and 216 were finally included.Results the lowest value of the average utility value was the posterior molar carious tooth with pain,the utility value was 0.31.The highest value was the posterior molar carious tooth restored after filling treatment,the utility value was 0.81.The utility value of the posterior molar with caries but no pain was 0.72,and the utility value of the posterior molar with caries needing further restoration was 0.60.The range of WTP/QATYs was 5 283.79～12 149.21 yuan/QATY,the highest was the posterior molar caries restored after filling treatment,the lowest was the posterior molar caries restored after further restoration.The WTP/QATYs average was 7 657.689 25 yuan/QATY.Conclusion This study measured dental health utility values based on the Chinese population,and measured willingness to pay per QATYs using contingent valuation,it can provide a reference for the future economic evaluation of oral health intervention projects.
