Evidence Map of Acupuncture as Treatment for Adult Health Conditions: Update from 2013 - 2021
Complementary and integrative health (CIH) options continue to grow in popularity among the general public as well as Veterans. In 2011, the Office of Patient Centered Care and Cultural Transformation (OPCC&CT) was established by VA, and in 2014 leadership launched the Integrative Health Coordinating Center (IHCC) to work to bring CIH approaches to the VA healthcare system. In 2017, the VA Whole Health System of care included acupuncture as one of its CIH modalities, offered in VA’s medical benefits package.
Responding to a request from OPCC&CT’s Integrative Health Coordinating Center, VA’s Evidence Synthesis Program (ESP) Center in Los Angeles, CA conducted this update to provide current evidence regarding the use of acupuncture for adult health conditions of interest to VA. Specifically, investigators sought to provide:
Investigators searched the literature for pertinent systematic reviews, including PubMed, Allied and Complementary Medicine Database (AMED), and the Cochrane Database of Systematic Reviews, which were searched from March 2013 to April 2021. The Database of Abstracts of Reviews of Effects (DARE) was search through 2014, when DARE ceased production. From 1,207 relevant citations, 370 publications were screened as full texts, and 64 reviews were selected for this report. The 64 reviews were categorized into 41 conditions, including headache, back pain, cancer-related pain, depression, and fibromyalgia, among others. The country of origin for reviews varied: China (N = 23), United States (N = 7), Korea (N = 6), Australia (N = 4), United Kingdom (N = 2), Brazil (N = 1), Italy (N = 1), Taiwan (N = 1), and multi-country (N=19).
Summary of Findings
There is a vast literature of original randomized trials and systematic reviews of randomized trials of acupuncture as a treatment for dozens of health conditions. Based on this literature, study investigators identified several conditions for which the authors of systematic reviews concluded that there is at least moderate certainty of evidence regarding health outcome effects of acupuncture; most of these involve comparisons of acupuncture to sham or control acupuncture.
The evidence mapping process resulted in six visual depictions of the evidence for acupuncture [see full report], with each condition plotted on the map based on the effect of acupuncture and certainty of evidence as reported in the systematic review. General observations from these maps include:

Implications for VA
Research Gaps/Future Research
Studies comparing acupuncture to placebo or sham are probably not the priority; rather the priority should be studies comparing acupuncture to other recommended therapies for the condition. In such studies, the type and schedule of acupuncture treatment needs careful documentation so findings can be applied in other settings. Studies comparing acupuncture to other recommended therapies also should have a sufficiently long follow-up period to allow any non-specific effects (i.e., of getting something “new”) to dissipate.
In the nine years covered by this update, investigators identified 370 new systematic reviews of acupuncture. These systematic reviews included about 370 new randomized controlled trials (RCTs) of acupuncture published over the same period of time and are included in the evidence maps. Thus, researchers interested in acupuncture are producing about as many systematic reviews (generally with low or very low certainty of evidence) as new RCTs needed to raise the certainty of evidence. This seems to be a mismatch between resources and need. The field of acupuncture would best be advanced with resources devoted to producing more high-quality RCTs and producing fewer new systematic reviews.
