ABSTRACT
OBJECTIVE：To know about the research status of health utility value obtained by mapping method in pharmacoeconomic evaluation ，and to provide reference for bibliometric study in pharmacoeconomic evaluation . METHODS ： Using“Mapping method ”“Health utility value ”“Cost-utility”“Utility point system ”as Chinese and English keywords ，retrieved from CNKI ，Wanfang database ，PubMed，Medline，Ebsco，Ovid and Wiley database ，empirical journal documents published from the inception to Dec. 31st，2018 about using mapping method to obtain health utility value were collected. The bibliometrics was used to statistically analyze basic information of included literature ，the construction and test of the model ，the type of the best model and so on. RESULTS ：The 124 included documents were all published in English journal. In the construction and testing of the mapping model ，the most frequently used econometric methods ，performance evaluation indicators and model testing methods were ordinary least squares （OLS），mean absolute error （MAE）and residual normality test ，application frequency of which were 97 times（31.60％），89 times（24.93％）and 62 times（21.09％）. There are 117 articles that define the best mapping model ，of which 101 articles（86.32％）have the best direct mapping effect. Most of the non-utility measurement scales adopted specific scales （92 articles，77.97％），and a few literatures adopted the universal scale （26 articles，22.03％）. The most utility measurement scales were 3-level European 5-dimensional health scale （79 articles，66.95％）. CONCLUSIONS ：The domestic empirical researches that use the mapping method to obtain health utility values need to be developed yet. A series of mapping models successfully developed by foreign scholars not only provide the feasibility of using non-utility measurement scales for cost-utility analysis ，but also provide more ideas for China to choose the corresponding econometric methods ，evaluation indicators and mapping methods in the empirical research of the mapping method in the future.
