Abstract

SummaryObjectiveThe aim of this paper is to describe the treatment and physician characteristics in a randomised trial of acupuncture for osteoarthritis of the knee.DesignThree-armed, randomised, controlled multicentre trial with 1-year follow-up.SettingTwenty-eight outpatient centres in Germany.InterventionsA total of 294 patients with osteoarthritis of the knee were randomised to 12 sessions of semi-standardised acupuncture (at least 6 local and 2 distant points needled per affected knee from a selection of predefined points, but individual choice of additional body or ear acupuncture points possible), 12 sessions of minimal acupuncture (superficial needling of at least 8 of 10 predefined, bilateral, distant non-acupuncture points) or a waiting list control (2 months no acupuncture).OutcomeParticipating trial physicians and interventions.ResultsForty-seven physicians specialised in acupuncture (mean age 43 ± 8 years, 26 females) provided study interventions in 28 outpatient centres in Germany. The median duration of acupuncture training completed by participating physicians was 350 h (range 140–2508). The total number of needles used was 17.4 ± 4.8 in the acupuncture group compared to 12.9 ± 3.3 in the minimal acupuncture group. In total, 39 physicians (83%) stated that they would have treated patients in either a similar or in exactly the same way outside of the trial, whereas 7 (15%) stated that they would have treated patients differently (1 missing).ConclusionsOur documentation of the trial interventions shows that semi-standardised acupuncture strategy represents an acceptable compromise for efficacy studies. However, a substantial minority of participating trial physicians stated that they would have treated patients differently outside of the trial.
