A preoperative interdisciplinary biopsychosocial opioid reduction program in patients on chronic opioid analgesia prior to spine surgery: A preliminary report and case series.

Background: Spine surgery candidates are commonly treated with long-term opioid analgesia. However, chronic opioid analgesia is associated with poor pain control, psychological distress, decreased functional status and operative complications. Therefore, our medical centre piloted an outpatient biopsychosocial interdisciplinary opioid reduction program for spine surgery candidates on chronic opioid analgesia.
Methods: Our case series reviews the outcomes of the first 5 interdisciplinary program completers. Data was collected on admission to the program, preoperatively at completion of the program, and 1 month postoperatively. We recorded changes in pain interference scores, physical functioning, and symptoms of depression and anxiety as captured by the Patient-Reported Outcome Measurement Information System (PROMIS-29) Profile.
Results: The mean duration of the preoperative opioid reduction program was 6-7 weeks. The mean morphine equivalent daily dose (SD) decreased from 238.2 (226.9)mg on admission to 157.1 (161.0)mg preoperatively and 139.1 (84.0)mg one month postoperatively. Similarly, the mean pain interference score (SD) decreased from 72.4 (5.1) on admission to 66.5 (6.9) preoperatively and 67.7 (5.4) one month postoperatively. The preoperative opioid dose and pain interference scores decreased in all 5 patients, but one month postoperatively increased in one patient related to a surgical complication. Pre- and post-operative depression, anxiety and fatigue improved in all patients. Satisfaction with participation in social roles, sleep disturbances, and physical functioning improved in most patients.
Conclusions: Pre- and post-operative pain improved despite the opioid dose being tapered. These preliminary data suggest that a short-term outpatient preoperative interdisciplinary biopsychosocial opioid reduction program is safe, feasible, and improves patient-centred outcomes.
Implications: Our preliminary data support the rationale for expansion of the opioid reduction program; opioid use and pain should be evaluated in all surgical candidates. These findings need to be replicated in larger studies.
