Abstract
Cluster randomized controlled trial. To improve quality of care for patients with low back pain (LBP) a multifaceted general practitioner education alone and in combination with motivational counseling by practice nurses has been implemented in German general practices. We studied effects on functional capacity (main outcome), days in pain, physical activity, quality of life, or days of sick leave (secondary outcomes) compared with no intervention. International research has lead to the development of the German LBP guideline for general practitioners. However, there is still doubt about the most effective implementation strategy. Although effects on process of care have been observed frequently, changes in patient outcomes are rarely seen. We recruited 1378 patients with LBP in 118 general practices, which were randomized to 1 of 3 study arms: a multifaceted guideline implementation (GI), GI plus training of practice nurses in motivational counseling (MC), and the postal dissemination of the guideline (controls, C). Data were collected (questionnaires and patient interviews) at baseline and after 6 and 12 months. Multilevel mixed effects modeling was used to adjust for clustering of data and potential confounders. After 6 months, functional capacity was higher in the intervention groups with a cluster adjusted mean difference of 3.650 between the MC group and controls (95% CI = 0.320-6.979, P = 0.032) and 2.652 between the GI group and controls (95% CI = -0.704 to 6.007, P = 0.120). Intervention effects were more pronounced regarding days in pain per year with an average reduction of 16 (GI) to 17 days (MC) after 6 months (12 and 9 days after 12 months) compared with controls. Active implementation of the German LBP guideline results in slightly better outcomes during 6 months follow-up than its postal dissemination. Results are more distinct when practice nurses are trained in motivational counseling.
Highlights
Low back pain (LBP) is one of the leading causes of consultations in general practice[1]
Active implementation of the German LBP guideline results in better outcomes during six months follow-up than its postal dissemination
The intervention arms received a multifaceted general practitioner education or the same education combined with a training of practice nurses in motivational counseling
Summary
Low back pain (LBP) is one of the leading causes of consultations in general practice[1]. The evidence of extensive research has been summarized 5 in international guidelines. All of them discourage diagnostic tests in unspecific LBP and emphasize patientsself-responsibility by promoting increased physical activity[3]. Until now there is no agreement on the best guideline implementation strategy. Recent reviews have shown that postal dissemination of guidelines alone or didactic 10 educational meetings, such as lectures, are not effective[4]. To achieve changes in practice, multifaceted interventions combining two or more components, such as information material and workshops, and an active approach, e.g. educational outreach visits, reminders and interactive educational meetings are necessary[5,6]. Results are inconsistent and mostly affect single aspects of patient 15 management[7,8]
