Abstract
Study Design: Retrospective case series. Objective: To determine risk factors associated with prolonged opioid use after lumbar fusion and to elucidate the effect of opioid use on patient-reported outcome measures (PROMs) after surgery. Methods: Patients who underwent 1–3 level lumbar decompression and fusion with at least one-year follow-up were identified. Opioid data were collected through the Pennsylvania Prescription Drug Monitoring Program. Preoperative “chronic use” was defined as consumption of >90 days in the one-year before surgery. Postoperative “prolonged use” was defined as a filled prescription 90-days after surgery. PROMs included the following: Short Form-12 Health Survey PCS-12 and MCS-12, ODI, and VAS-Back and Leg scores. Logistic regression was performed to determine independent predictors for prolonged opioid use. Results: The final analysis included 260 patients. BMI >35 (OR:.44 [.20,.90], P =.03) and current smoking status (OR: 2.73 [1.14, 6.96], P =.03) significantly predicted postoperative opioid usage. Chronic opioid use before surgery was associated with greater improvements in MCS-12 (β= 5.26 [1.01, 9.56], P =.02). Patients with prolonged opioid use self-reported worse VAS-Back (3.4 vs 2.1, P =.003) and VAS-Leg (2.6 vs 1.2, P =.03) scores after surgery. Prolonged opioid use was associated with decreased improvement in VAS-Leg over time (β =.14 [.15, 1.85], P =.02). Conclusions: Current smoking status and lower BMI were significantly predictive of prolonged opioid use. Excess opioid use before and after surgery significantly affected PROMs after lumbar fusion.
