RT Journal Article SR Electronic T1 Acupuncture trials and informed consent JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 43 OP 44 DO 10.1136/jme.2006.016535 VO 33 IS 1 A1 F G Miller A1 T J Kaptchuk YR 2007 UL http://jme.bmj.com/content/33/1/43.abstract AB Participants are often not informed by investigators who conduct randomised, placebo-controlled acupuncture trials that they may receive a sham acupuncture intervention. Instead, they are told that one or more forms of acupuncture are being compared in the study. This deceptive disclosure practice lacks a compelling methodological rationale and violates the ethical requirement to obtain informed consent. Participants in placebo-controlled acupuncture trials should be provided an accurate disclosure regarding the use of sham acupuncture, consistent with the practice of placebo-controlled drug trials.
