Abstract

Objective: To evaluate the quality of the published breast cancer screening guidelines to provide a reference for domestic studies in the future. Methods: PubMed, Embase, Cochrane Library, Web of Science, SinoMed, China National Knowledge Infrastructure, VIP, and Wanfang Data were searched to identify breast cancer screening guidelines on until August 2020. Two reviewers screened literature and extracted data independently. The Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREEⅡ) and Reporting Items for Practice Guidelines in Healthcare(RIGHT) tools were used to evaluate the quality of the included guidelines. Results: A total of 15 breast cancer screening guidelines were included, of which seven were published in the United States, with publication years focusing on 2015 to 2019, and 11 guidelines had updated versions. "Rigour of development" (47.0%±22.1%) and "Applicability" (44.0%±15.1%) of AGREEⅡ scored lower than other domains. "Review and quality assurance" (46.7%±39.9%) and "Funding, declaration, and management of interests" (41.7%±24.4%) of RIGHT were reported poorer than others. There were six guidelines recommended and another nine recommended with modifications based on the overall AGREEⅡ score. There were four guidelines with a good level, and another 11 were with a moderate level of RIGHT. The National Comprehensive Cancer Network published the best overall quality guidelines in 2018 (AGREEⅡ: 83.3%, RIGHT: 80.0%) and by the American Cancer Society in 2015 (AGREEⅡ: 83.3%, RIGHT: 85.7%). Conclusion: The quality of breast cancer screening guidelines was predominantly of moderate quality, and greater attention should be paid to the guideline development process and quality control of the guidelines.
