Abstract

Several systematic reviews suggest that acupuncture is effective for knee osteoarthritis, and furthermore a safe and cost-effective treatment for this condition. A recent Clinical Practice Guideline (CPG) from the National Institute for Health and Care Excellence (NICE), in the UK recommended against the use of acupuncture on the grounds that the effect size in comparison to sham acupuncture is too small. Safety data was not considered in the review, additionally the levels of evidence for acupuncture against other recommended therapies was not compared. Consequently, we argue that this NICE guideline has limitations that lead to several potential biases in its evaluation of acupuncture, which were not addressed correctly: (i) NICE's prior scoping process limited their review (ii) NICE introduced the method of developing recommendations based on the consideration of which interventions make ’minimal important differences’ (MID) of an effect size of 0.5 or greater, rather than the statistical significance of the effect of an intervention when compared to an appropriate comparison. (iii) Evidence that sham acupuncture is not physiologically inert, and has some level of beneficial effect, hence artificially reducing the magnitude of the effect size in comparison to sham; (iv) The low adverse effects profile of acupuncture; (v) Evidence from trials comparing acupuncture to usual or standard care was not considered, nor was cost-effectiveness data. (vi) Lack of the usual CPG “head to head” comparisons between interventions. If the same criteria and methods that have been applied to acupuncture were applied to other NICE recommended therapies for knee osteoarthritis, including patient centeredness, patient education, self-management and weight loss, NSAIDs and COX-2 inhibitors, these too would no longer be recommended and opiates would become the first line of drug prescription. Given the problems with sham acupuncture, perhaps now is the time to embrace pragmatic studies and employ comparative effectiveness studies instead.
