Acupuncturist’s Unconvincing Attempt at Damage Control

Acupuncture has been in the news recently. A former President of South Korea had to undergo major surgery to remove an acupuncture needle that had somehow lodged in his lung.  A recent study in Pain compiled a list of 95 published reports of serious complications of acupuncture including 5 deaths. Meanwhile, acupuncturists continue to insist that their procedures are “safe.”

Edzard Ernst et al.’s article Acupuncture: Does it alleviate pain and are there serious risks? A review of reviews was published in the journal Pain in April 2011. It had two parts: (1) it was a systematic review of 57 systematic reviews showing that there was “little truly convincing evidence that acupuncture is effective in reducing pain,” and (2) it tabulated published reports of 5 deaths and 90 other serious complications of acupuncture treatments. I wrote an accompanying commentary, “Acupuncture’s claims punctured: Not proven effective for pain, not harmless.”

William Morris chastised me for not declaring a conflict of interest (!?) in my commentary. Now, in Acupuncture Today, he has criticized the Ernst et al. study itself.

Hyping Health Risks

Three kids on the same block were diagnosed with leukemia last year. That couldn’t happen just by chance, could it? There MUST be something in the environment that caused it (power lines, the chemical plant down the street, asbestos in their school, iPods, Twinkies?). Quick, let’s measure everything we can think of and compare exposures to other blocks and find an explanation.

That may be the common reaction, and it may seem plausible to the general public, but it’s not good science.

I have just read a book that does a great job of elucidating the pitfalls of epidemiologic studies, the problematic interface between science and emotion-laden public concerns, and the way environmental hazards have been hyped far beyond the evidence. Hyping Health Risks: Environmental Hazards in Daily Life and the Science of Epidemiology by Geoffrey C. Kabat.

He covers the uses, strengths and limitations of epidemiology, discusses the pros and cons of different study designs, and explains how to judge whether an association is causal.
