This article aims to explore the application of health economics evidence in the development of clinical practice guidelines and evidence recommendations, and to provide better references for clinical decision-making. By reviewing the use of health economics evidence in domestic and international clinical practice guidelines, the difficulties in the application of health economics evidence in the development of clinical practice guidelines and evidence recommendations were summarized. It was found that there were significant differences in the use of health economics evidence in clinical practice guidelines in different countries, and these differences were affected by the goals of clinical practice guidelines and limitations of health economics evidence itself, lacking standardized methodological guidance, resulting in limited use of health economics evidence in clinical practice guidelines. Therefore, further research is needed to optimize the integration of health economics and clinical practice guidelines, and develop standardized methodological guidance.
