Objective This study aims to conduct a systematic review and quality assessment of published domestic and foreign studies on the pharmacoeconomics of Chinese patent medicines, with the goal of identifying relevant issues and proposing improvement suggestions. Methods The methods used in this study involved systematic searches of the CNKI, WanFang Data, VIP, and PubMed databases for domestic and foreign studies related to the pharmacoeconomics of Chinese patent medicines, with a search deadline of May 20, 2022. The studies were evaluated systematically based on various aspects such as title, year, author, journal, research perspective, research type, disease area, research object, research design type, research method, application model, model calibration, sensitivity analysis, cost calculation, effectiveness indicators, and adverse reaction comparison. The evaluation of report quality and methodological quality was conducted using the consolidated health economic evaluation reporting standards 2022 (CHEERS 2022) and the quality of health economic studies (QHES) tools, respectively. Results This study included a total of 249 articles, including 247 in Chinese and 2 in English. The first article on the pharmacoeconomics of Chinese patent medicine was published in 2000. The diseases studied covered 59.26% of the ICD-11 disease areas. Articles reporting on the research perspective accounted for 16.87% of the total number of studies, while 32.4% of studies provided an explanation of the research type. The main method used was cost-effectiveness analysis, accounting for 86.75% of the studies, and the main cost component was direct medical costs, accounting for 89.56%. The primary effectiveness indicator was the overall effective rate, accounting for 78.31% of the studies. The average compliance rate with the CHEERS 2022 standard was 43.58%, and the average QHES score was 56.7. Conclusion A considerable part of the existing research on the pharmacoeconomics of traditional Chinese medicine (TCM) suffers from problems such as the lack of research methods or non-standardized methods. Therefore, the relevant research abilities of researchers who conduct TCM pharmacoeconomic research need to be improved.
