QuestionAre implementation strategies involving education any more effective than mere dissemination of clinical practice guidelines in changing physiotherapy practice and reducing patient disability after acute whiplash?DesignCluster-randomised trial.ParticipantsTwenty-seven physiotherapists from different private physiotherapy clinics and the 103 patients (4 dropouts) who presented to them with acute whiplash.InterventionThe implementation group of physiotherapists underwent education by opinion leaders about whiplash guidelines and the dissemination group had the guidelines mailed to them.Outcome MeasuresThe primary outcome was patient disability, measured using the Functional Rating Index, collected on admission to the trial and at 1.5, 3, 6 and 12 months. Physiotherapist knowledge about the guidelines was measured using a custom-made questionnaire. Physiotherapist practice and cost of care were measured by audit of patient notes.ResultsThere were no significant differences between groups for any of the patient outcomes at any time. The implementation patients had 0.6 points (95% CI -7.8 to 6.6) less disability than the dissemination patients at 12 months; 44% more physiotherapists in the implementation group reported that they prescribed two out of the five guideline-recommended treatments; and 32% more physiotherapists actually prescribed them. The cost of care for patients in the implementation group was $255 (95% CI -1505 to 996) less than for patients in the dissemination group.ConclusionAlthough the active implementation program increased guideline-consistent practice, patient outcomes and cost of care were not affected.
