ObjectiveWe aimed to assess the impact of a booklet integrating the biopsychosocial model of chronic pain management on reducing disability among patients undergoing lumbar discetomy. MethodsIn a prospective, controlled, time-series study with an alternate-month design, we enrolled 129 patients from a tertiary care university hospital after they underwent uncomplicated lumbar discectomy for the first time. The intervention group received the biopsychosocial evidence-based booklet and the control group a biomedical-based booklet; the booklets differed only in information content. Patients were blinded to treatment group. The main outcome was disability at 2 months (measured by the Quebec back-pain disability scale [QBPDS]). Secondary outcomes were fear and avoidance beliefs measured by the Fear-Avoidance Beliefs Questionnaire (FABQ). All data were collected by self-reporting questionnaires. ResultsAt 2 months, disability did not differ between the 2 groups (QBPDS score 32.4±22.8 vs 36.1±18.7, P=0.36). FABQ physical activity score was lower with the evidenced-based booklet as compared with controls (8.0±7.14 vs 11.2±6.3, P=0.008). ConclusionsProviding an evidence-based booklet had no effect at 2 months after surgery on disability but reduced fear-avoidance beliefs about physical activity. This booklet could be an effective tool for health care professionals in helping with patient education. ClinicalTrials.gov identifierNCT00761111.
