Interventions for improvement of primary care in patients with low back pain:: How effective are advice to primary care physicians on therapies and a multimodal therapy program arising out of cooperation of outpatient health care structures?

Background. Treatment for chronic low back pain in primary care has a poor-quality outcome. There is evidence that multimodal therapy is the most successful approach to its management. We tried to evaluate whether giving primary care physicians evidence-based recommendations on therapy of chronic back pain or directly implementing a multimodal program would improve the outcome of patients with low back pain treated in primary care. Methods. In the first phase, physicians were asked to document the course of patients suffering from low back pain of at least 4 weeks' duration with no decrease in intensity, noting pain intensity before and after 6 months of conventional, nonsurgical treatments. In the present, second, phase of the study, recommendations issued by the Medicines Committee of the German Medical Profession and the U.S. Agency for Health Care Policy and Research for the management of back pain were presented to doctors in printed form and at conferences. In parallel with this, a multimodal program for the treatment of chronic low back pain (4 h/day for 20 days: medical training therapy, cognitive-behavioral therapy, physiotherapy, and patient education) was organized in a private health-oriented sports center in cooperation with three private physiotherapy practices, and a psychologist and a pain specialist from the outpatient pain clinic at the University Hospital in Erlangen. We examined how physicians changed the therapy and how effective it was, the latter as reflected in the mean sum value of the percent pre- to posttreatment changes in pain intensity, how much pain interfered with daily living, depressivity, and quality of life. Data after interventions were compared with baseline data from the first phase. Results. Data relating to 36 patients following treatment by 14 primary care physicians who had been given information about therapy recommendations and to 51 patients who had participated in the muitimodal therapy program were compared with baseline data recorded in 157 patients. Recommendations changed neither the therapy preferred by primary care physicians nor the quality of outcome of conventional treatment. In contrast,the multimodal program of therapy for chronic low back pain improved the outcome significantly more than conventional therapy (mean improvement in general outcome score 22 vs. 7%, respectively, compared with baseline data; P<0.001). Conclusions. Giving primary care physicians information on the therapy recommended for treatment of low back pain does not lead to any change in physicians' preferred therapy. Multimodal programs for treatment of chronic low back pain should be organized locally, with existing health care providers joining forces to improve the quality of outcome in chronic low back pain managed in primary care.
