Abstract

Retrospective longitudinal cohort.We investigated opioid prescribing patterns amongst adults in the United States diagnosed with low back or lower extremity pain (LBP/LEP) who underwent spine surgery.Opioid-based treatment of LBP/LEP and postsurgical pain have separately been associated with chronic opioid use, but a combined and large-scale cohort study is missing.This study utilizes commercial inpatient, outpatient, and pharmaceutical insurance claims. Between 2008 and 2015, patients without prior prescription opioids with a new diagnosis of LBP/LEP who underwent surgery within one year after diagnosis were enrolled. Opioid prescribing patterns after LBP/LEP diagnosis and after surgery were evaluated. All patients had one-year postoperative follow-up. Low and high frequency (=6 refills in 12 months) opioid prescription groups were identified.25,506 patients without prior prescription opioids were diagnosed with LBP/LEP and underwent surgery within one year of diagnosis. After LBP/LEP diagnosis, 18,219 (71.4%) were prescribed opioids while 7,287 (28.6%) were not. After surgery, 2,952 (11.6%) were prescribed opioids with high frequency and 22,554 (88.4%) with low frequency. Among patients prescribed opioids prior to surgery, those with high frequency prescriptions were more likely to continue this pattern postoperatively than those with low frequency prescriptions preoperatively (OR:2.15, 95% CI:1.97-2.34). For those prescribed opioids preoperatively, average daily morphine milligram equivalent (MME) decreased after surgery (by 2.62 in decompression alone cohort and 0.25 in arthrodesis cohort, p?
