Simple educational intervention to improve the recovery from acute whiplash: Results of a randomized, controlled trial

Objectives: To determine if an educational intervention in the acute stage of whiplash injury may improve the recovery rate. Methods: Consecutive subjects were randomized to one of two treatment groups: educational intervention or usual care. The intervention group received an educational pamphlet based on the current evidence. The control group did not receive these materials but received usual emergency department care and a standard nondirected discharge information sheet. Both groups underwent follow-up by telephone interview at two weeks and three months. The primary outcome measure of recovery was the patient's response to the question, "How well do you feel you are recovering from your injuries?" Results: A total of 112 subjects agreed to participate. Age, gender, precollision employment level and health, initial symptoms, collision parameters, and emergency treatments were similar between the groups. At two weeks postcollision, 7.3% in the treatment group reported recovery compared with 8.8% in the control group (absolute risk difference, -1.5%; 95% confidence interval = -12.6% to 9.7%). At three months postcollision, 21.8% in the treatment group reported complete recovery compared with 21.0% in the control group (absolute risk difference, 0.8%; 95% confidence interval = -14.4% to 16.0%). At three months, there were no clinically or statistically significant differences between groups in severity of remaining symptoms, limitations in daily activities, therapy use, medications used, lost time from work, or litigation. Conclusions: An evidence-based educational pamphlet provided to patients at discharge from the emergency department is no more effective than usual care for patients with grade 1 or 2 whiplash-associated disorder.
