We aimed to assess the impact of a booklet integrating the
biopsychosocial model of chronic pain management on reducing disability among
patients undergoing lumbar discetomy. METHODS: In 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. RESULTS: At 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). CONCLUSIONS: Providing 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 IDENTIFIER:
