Background: Eczema is a common chronic relapsing inflammatory skin disease, which is characterized by intense itching. Acupuncture can be effective for eczema, and it is thus regarded as a common complementary treatment.
Objective: The intention of this overview is to methodically appraise and synthesize evidence about systematic reviews/meta-analyses (SRs/MAs) on acupuncture in eczema.
Methods: We searched for SRs/MAs of acupuncture with eczema in eight databases. We evaluated the methodological quality by Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), the reporting quality with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020 Checkist), and the evidence quality according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.
Results: A total of 7 SRs/MAs were included. According to AMSTAR-2, all the SRs/MAs included were categorized as critically low-quality. According to the PRISMA 2020 checklist, none of the reviews completed all the 27 items, thus their compliance was relatively weak. On the base of GRADE system, 2 of the 12 outcomes were rated as moderate, and 5 outcomes were rated as low-quality, while the others were regarded as very low-quality.
Conclusion: Compared with the control group, the included reviews of the acupuncture group were more effective and safer; however, the conclusion should be treated cautiously because the quality of evidence was not high enough to support it. In order to improve the quality, more rigorous, standardized, and comprehensive SRs/MAs need designing in the future.
