Classifying chronic opioid use before spine surgery: comparison of self-report and prescription drug monitoring program (PDMP) reporting

Preoperative Opioid Use Is Associated With Inferior Patient-Reported Outcomes Measurement Information System Scores Following Rotator Cuff Repair

PURPOSE

To determine the influence of preoperative opioid use on Patient-Reported Outcomes Measurement Information System (PROMIS) scores pre- and postoperatively in patients undergoing arthroscopic rotator cuff repair (RCR).

METHODS

A retrospective review of all RCR patients aged >18 years old was performed. PROMIS pain interference ("PROMIS PI"), upper extremity function ("PROMIS UE"), and depression ("PROMIS D") scores, were reviewed. These measures were collected at preoperative, 6-month, and 1-year postoperative time points. A prescription drug-monitoring program was queried to track opioid prescriptions. Patients were categorized as chronic users, acute users, and nonusers based on prescriptions filled. Comparison of means were carried out using analysis of variance and least squares means. Effect sizes and 95% confidence intervals were calculated.

RESULTS

In total, 184 patients who underwent RCR were included. Preoperatively, nonusers (n = 92) had superior PROMIS UE (30.6 vs 28.9 vs 26.1; P < .05) and PI scores (61.5 vs 64.9 vs 65.3; P < .001) compared with acute users (n = 65) and chronic users (n = 27), respectively. At 6 months postoperatively; nonusers demonstrated significantly greater PROMIS UE (41.7 vs 35.6 vs. 33.5; P < .001), lower PROMIS D (41.6 vs 45.8 vs 51.1; P < .001), and lower PROMIS PI scores (50.7 vs 56.3 vs 58.1; P < .01) when compared with acute and chronic users, respectively. Nonusers had lower PROMIS PI (47.9 vs 54.3 vs 57.4; P < .0001) and PROMIS D (41.6 vs 48.3 vs 49.2; P = .0002) scores compared with acute and chronic users at 1-year postoperatively. Nonusers experienced a significantly greater magnitude of improvement in PROMIS D 6 months postoperatively compared with chronic opioid users (-5.9 vs 0.0; P < .01).

CONCLUSIONS

Patients undergoing RCR demonstrated superior PROMIS scores pre- and postoperatively if they did not use opioids within 3 months before surgery.

How Many Steps Per Day During the Early Postoperative Period are Associated With Patient-Reported Outcomes of Disability, Pain, and Opioid Use After Lumbar Spine Surgery?

OBJECTIVE

To investigate whether early postoperative walking is associated with "best outcome" and no opioid use at 1 year after lumbar spine surgery and establish a threshold for steps/day to inform clinical practice.

DESIGN

Secondary analysis from randomized controlled trial.

SETTING

Two academic medical centers in the United States.

PARTICIPANTS

We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition (N=248). A total of 212 participants (mean age, 62.8±11.4y, 53.3% female) had valid walking data at baseline.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Disability (Oswestry Disability Index), back and leg pain (Brief Pain Inventory), and opioid use (yes vs no) were assessed at baseline and 1 year after surgery. "Best outcome" was defined as Oswestry Disability Index ≤20, back pain ≤2, and leg pain ≤2. Steps/day (walking) was assessed with an accelerometer worn for at least 3 days and 10 h/d at 6 weeks after spine surgery, which was considered as study baseline. Separate multivariable logistic regression analyses were conducted to determine the association between steps/day at 6 weeks and "best outcome" and no opioid use at 1-year. Receiver operating characteristic curves identified a steps/day threshold for achieving outcomes.

RESULTS

Each additional 1000 steps/d at 6 weeks after spine surgery was associated with 41% higher odds of achieving "best outcome" (95% confidence interval [CI], 1.15-1.74) and 38% higher odds of no opioid use (95% CI, 1.09-1.76) at 1 year. Walking ≥3500 steps/d was associated with 3.75 times the odds (95% CI, 1.56-9.02) of achieving "best outcome" and 2.37 times the odds (95% CI, 1.07-5.24) of not using opioids.

CONCLUSIONS

Walking early after surgery may optimize patient-reported outcomes after lumbar spine surgery. A 3500 steps/d threshold may serve as an initial recommendation during early postoperative counseling.
