Moxibustion for the treatment of primary dysmenorrhea: Protocol for an overview of systematic reviews

BACKGROUND: Primary dysmenorrhea (PD) is a common gynecological disease, it refers to spasmodic pain in the lower abdomen before, after or during menstruation, accompanied by general discomfort, In severe cases, fainting may occur due to severe pain, reducing the quality of patients’ life and imposing a heavy burden on social medical security system. There are many ways to treat primary dysmenorrhea, including western medicine and traditional Chinese medicine. Moxibustion is one of the traditional Chinese medicine treatments for primary dysmenorrhea, especially popular in China. Therefore, our overview aims at evaluating the methodological bias and the reliability of the conclusions of systematic reviews (SRs) about moxibustion for primary dysmenorrhoea, and help clinical decision makers translate this research into clinical policy and practice. METHODS: We will search electronic databases including PubMed, Embase, Cochrane Library, Chinese Biomedical Literatures Database (CBM), China National Knowledge Infrastructure (CNKI), WangFang Database (WF), Chinese Scientific Journal Database (VIP) from inception to February 2017. We will consider systematic reviews and meta-analysis of randomized controlled trials evaluating the effect of moxibustion for PD. Two reviewers will identify relevant studies, extract data information, and then assess the methodological quality by Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) tool. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) report checklist to assess the quality of reports included in the study. We will use the evaluations of the Classification of Recommendations, Evaluation, Development and Evaluation (GRADE) of the authors of the included systematic reviews. The screening of systematic reviews, eligibility evaluation, data extraction, methodological quality, and quality of evidence will be conducted by independent reviewers in pairs. The outcomes of interest include: total effective rate, visual analog scale scores (VAS), Cox Menstrual Symptom Scale (CMSS), Dysmenorrhea symptom score and adverse events outcomes prioritized in the individual reviews. We will extract data onto a predefined form designed to summarize the key characteristics of each review. The evidence will be a narrative synthesis organized around the type and content of the intervention and the results reported. RESULTS: The results of this study will be published in a peer-reviewed journal. CONCLUSIONS: We expect to compile evidence from multiple systematic reviews of symptomatic improvement in patients with primary dysmenorrhea in an accessible and useful document.
