        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.
