Study of health state disutility value estimation of malignant tumor drugs-related adverse events ：a systematic review / 中国药房

ABSTRACT

OBJECTIVE To provide methodology re ference for conducting health state disutility estimation and calculating health output in pharmacoeconomic evaluation. METHODS Literatures about health state disutility estimation of malignant tumor drugs-related adverse events were retrieved from 3 Chinese databases such as CNKI ，Wanfang database and VIP and 3 English database such as PubMed ，Web of Science and the Cochrane Library from inception to July 2021. After 2 researchers independently screened the literature and extracted the data ，qualitative analysis was conducted. The modified decision-making technical support documents of the National Institute for Health and Care Excellence were used for quality evaluation. The practice and existing problems of health state disutility measurement were summarized to put forward some suggestions. RESULTS A total of 77 literatures were included. The first literature was published in 1991，and the number of publications increased in a fluctuating manner. 77 literatures involved 120 kinds of adverse events ，mainly utility studies （49，63.64％），only 3 （3.90％） were investigated in China. A total of 35 literatures（45.45％）had no statement of study design type ，48（62.34％）had no statement of health status development method ，52（67.53％）had no statement of health status verification method ，46（59.74％）set and explained the basic health status ，and 20（25.97％）were ranked for the health status . The utility measurement tools used were mainly the standard game method and the European five-dimensional health scale （23 literatures each ，accounting for 29.87％）. The research objects of 45 literatures（58.44％）were patients ，and 63（81.82％）did not specify the representative test of the population. Utility report types included negative value ，non-negative value and non-negative value of consolidated basic status. A total of 45 literatures（58.44％）had no statement of statistical method of utility. Overall quality score of included studies was 0.683. CONCLUSIONS The current disutility estimation include 4 key links of basic study design ， health status confirmation， utility estimation survey and survey data E-mail：luyuqiong96@foxmail.com statistics. The deficiencies of related studies are the lack of data based on the Chinese population ，the inconsistent type ofresult reporting ，and the incomplete report of measurement- related critical items. It is recommended to standardize the basic implementation path of disutility estimation ，formulate guidelines for health status utility value estimation ，and strengthen multidisciplinary cooperation so as to improve the quality of health status utility value estimation .
