Study Design: Retrospective review of electronic medical records (EMR)., Objective: This study aims to (1) characterize the pattern of opioid utilization in patients undergoing spine surgery and (2) compare the postoperative course between patients with and without chronic preoperative opioid prescriptions., Summary of Background Data: Postoperative pain management for patients with a history of opioid usage remains a challenge for spine surgeons. Opioids are controversial in this setting due to side effects and potential for abuse and addiction. Given the increasing rate of opioid prescriptions for spine-related pain, more studies are needed to evaluate patterns and risks of preoperative opioid usage in surgical patients., Methods: EMR were reviewed for patients (age > 18) with lumbar spinal stenosis undergoing lumbar laminectomy in 2011 at our institution. Data regarding patient demographics, levels operated, pre/postoperative medications, and in-hospital length of stay were collected. Primary outcomes were length of stay and duration of postoperative opioid usage., Results: One hundred patients were reviewed. Fifty-five patients had a chronic opioid prescription documented at least 3 months before surgery. Forty-five patients were not on chronic opioid therapy preoperatively. The preoperative opioid group compared with the non-opioid group had a greater proportion of females (53% vs. 40%), younger mean age (63 yrs vs. 65 yrs), higher frequency of preoperative benzodiazepine prescription (20% vs. 11%), longer average in-hospital length of stay (3.7 d vs. 3.2 d), and longer duration on postoperative opioids (211 d vs. 79 d)., Conclusion: Patients on chronic opioids prior to spine surgery are more likely to have a longer hospital stay and continue on opioids for a longer time after surgery, compared with patients not on chronic opioid therapy. Spine surgeons and pain specialists should seek to identify patients on chronic opioids before surgery and evaluate strategies to optimize pain management in the pre- and postoperative course., Level of Evidence: 3.

Study Design: Retrospective cohort study., Objective: To (1) confirm validity of Patient-Reported Outcomes Measurement Information System (PROMIS) physical function and pain interference computer-adaptive tests (CATs) and (2) assess the validity of PROMIS Global Health (GH) and five additional PROMIS CATs: social role satisfaction, fatigue, anxiety, depression, and sleep disturbance in a population of patients with chronic low back pain (cLBP) who completed a 3-month Interdisciplinary Pain Program (IPP)., Summary of Background Data: Recent recommendations for assessing outcomes in patients with cLBP have included PROMIS scales; however, there is a need for further evaluation, and PROMIS GH has not been studied in this population., Methods: The study cohort included patients with cLBP who completed the entirety of a 3-month IPP between August 2016 and December 2018. Patient-reported outcome measures (PROMs) were analyzed before the start of the IPP and at graduation. Convergent and discriminant validity were evaluated using Pearson correlation coefficients. Known groups' validity assessed the change in PROMIS scores stratified by improvement on the Modified LBP Disability Questionnaire. Responsiveness was evaluated with standardized response means based on global impression of change., Results: IPP was completed by 217 patients (67.7% women, age 53.8 ± 12.8). Convergent validity was supported (P < 0.01 for all pairwise PROMs comparisons). All PROMs improved significantly by graduation, with the largest improvement for PROMIS pain interference, physical function, social role satisfaction, and Modified LBP Disability Questionnaire. Known groups' validity demonstrated the greatest change on PROMIS physical function, social role satisfaction, pain interference, and depression. Responsiveness was supported for all PROMs in 170 (78.3%) patients who indicated at least minimal improvement (standardized response means 0.43-1.06)., Conclusion: Our study provides support of PROMIS CATs, highlights the importance of including other meaningful outcome measures, such as social role satisfaction, and provides the first validation of PROMIS GH, in patients with cLBP. PROMs collection can be streamlined through the use of PROMIS CATs which offer advantages over legacy measures., Level of Evidence: 3.

Study Design: This is an observational cohort study., Objective: The aim of this study was to compare the effectiveness of PT to an interdisciplinary treatment approach in patients with chronic low back pain (CLBP)., Summary of Background Data: CLBP is a costly and potentially disabling condition. Physical therapy (PT), cognitive behavioral therapy, and interdisciplinary pain programs (IPPs) are superior to usual care. Empirical evidence is lacking to clearly support one treatment approach over another in patients with CLBP., Methods: One hundred seventeen adult patients who completed an IPP for individuals with ≥3 months of back pain were compared to 214 adult patients with similar characteristics who completed PT. The Modified Low Back Pain Disability Questionnaire was the primary outcome measure. Additional measures included: PROMIS physical function, global health, social role satisfaction, pain interference, anxiety, fatigue, sleep disturbance, and Patient Health Questionnaire. Patients who completed the IPP were matched by propensity score to a historical control group of patients who completed a course of PT. Change in functional disability was compared between IPP patients and matched controls. Patient-reported outcome measures were assessed pre to post participation in the IPP using paired t test and by calculating the proportion with clinically meaningful improvement., Results: Propensity score matching generated 81 IPP and 81 PT patients. Patients enrolled in the IPP had significantly greater improvement in MDQ scores upon completion compared to patients in PT (15.8 vs. 7.1, P < 0.001). The majority of IPP patients reached the threshold for clinically meaningful change of ≥10 point reduction (60.5%) compared to 34.6% of PT patients, P < 0.01. Patients in the IPP also showed statistically and clinically significant improvement in social role satisfaction, fatigue, and sleep disturbance., Conclusion: CLBP patients in an IPP demonstrated greater functional improvements compared to similar patients participating in PT., Level of Evidence: 3.
