Efficacy and safety of abdominal acupuncture for insomnia: A protocol of systematic review and meta-analysis

BACKGROUND: Insomnia is characterized by high incidence, easy recurrence, and difficulty in curing. Serious insomnia not only seriously affects the body organ function, but psychological patients also cause great damage. Abdominal acupuncture (AA) has fewer side effects and is increasingly used to treat insomnia. This study aimed to systematically review the effectiveness and safety of abdominal acupuncture in the treatment of insomnia. METHODS: Literature on abdominal acupuncture for insomnia in the PubMed, Excerpt Medica Database(Embase), Cochrane Central Register of Controlled Trials, Web of Science, China National Knowledge Infrastructure Database, China Biomedical Literature Database, Chinese Scientific Journal Database, and Wan Fang databases were searched from the creation of these databases to October 3, 2021. In addition, the reference lists of studies meeting the inclusion criteria will also be searched to achieve a comprehensive retrieval of the maximum. All randomized controlled trials of AA for treating insomnia were included. Two reviewers will conduct literature screening, data extraction, and quality evaluation respectively. The main outcome was the Pittsburgh Sleep Quality Index, and the secondary outcomes included clinical efficacy and safety. RevMan 5.4.1 software was used for mate analysis. RESULTS: This study aimed to evaluate the current status of AA treatment for insomnia, with the aim of illustrating the effectiveness and safety of abdominal acupuncture. CONCLUSION: This study will provide high-quality evidence to evaluate the effectiveness and safety of AA in treating insomnia. Registration: INPLASY2021100088
