[Quality assessment on randomized sham-acupuncture controlled trials of acupuncture for primary insomnia over the past decade].

Researchers examined the quality of scientific studies testing acupuncture for primary insomnia, specifically looking at trials that compared real acupuncture to sham (fake) acupuncture. They reviewed 37 studies published over the past decade, including 31 in Chinese and 6 in English. The review found significant problems with how these studies were designed and reported. Many studies failed to properly describe important details like how they assigned patients to groups, whether participants knew which treatment they received, or how they calculated the number of patients needed. The fake acupuncture methods varied widely across studies—some used needles that didn't actually pierce the skin, while others inserted needles shallowly into non-therapeutic points. When measured against international standards for clinical trial reporting (CONSORT), acupuncture intervention reporting (STRICTA), and sham acupuncture reporting (SHARE), most studies fell short. Chinese-language studies had particularly low reporting rates, with over 60% of important details missing or poorly described. This matters for patients because poor study quality makes it harder to know whether acupuncture truly helps insomnia or how it compares to placebo effects. The researchers recommend that future studies follow stricter guidelines to provide more reliable evidence about acupuncture's effectiveness for sleep problems. If you're considering acupuncture for insomnia, consult with a licensed acupuncturist who can discuss realistic expectations based on current evidence.

This systematic review assessed reporting quality of 37 randomized sham-acupuncture controlled trials for primary insomnia published 2014-2024 using CONSORT, STRICTA, and SHARE criteria. The analysis included 31 Chinese and 6 English-language studies employing eight different sham-acupuncture designs, predominantly non-penetrating needles or shallow insertion at non-acupoints. Median quality scores were notably low: CONSORT (16), STRICTA (11), and SHARE (8). Chinese-language publications showed 62.16% of CONSORT items below 50% reporting rate, with 9 items at 0% compliance. English publications performed better with 13 items at 100% reporting. STRICTA compliance was superior overall, though Chinese studies still showed deficiencies in 29.41% of items. SHARE checklist compliance was poorest, with 68.42% of items under 50% reporting in Chinese studies. Critical methodological gaps included inadequate blinding implementation, missing sample size calculations, and absent trial registration. The findings indicate substantial heterogeneity in sham-acupuncture methodology and poor adherence to international reporting standards, significantly limiting evidence reliability for clinical decision-making in treating insomnia with acupuncture.
