RESUMO
Objective:To re-evaluate the methodological quality, evidence quality and reporting quality of the systematic review and meta analysis of Traditional Chinese Medicine (TCM) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:We searched the databases of CNKI, Wanfang, VIP, Cochrane Library, PubMed, EMbase, and retrieved the systematic reviews or meta-analysis literatures on the treatment of AECOPD with TCM from the establishment of the database to February 28, 2021. We applied AMSTAR2 scale and GRADE Tools, PRISMA statement to evaluate methodological quality, evidence quality and report quality.Results:A total of 15 systematic reviews were included, including 85 outcome indicators. The evaluation results of AMSTAR2 scale showed that 9 articles were low-quality methodology and 6 articles were very low-quality methodology. The GRADE results showed that the quality of evidence for 23 outcome indicators was moderate, the quality of evidence for 30 outcome indicators was low, and the quality of evidence for 32 outcome indicators was very low. The results of the PRISMA statement showed that the quality of the reporting is relatively adequate.Conclusion:TCM combined with western medicine can improve the clinical efficacy of AECOPD to a certain extent, but the methodological quality of reviews and the quality of evidence are generally low. In the future, researchers should standardize the writing of systematic reviews/meta-analysis, in order to provide clinicians with more authentic and reliable evidence-based evidence.
