Median morphine milligram equivalents (MMEs) were not significantly different (40.2 vs. 42.7; P =0.287). Of the cohort, 26.3% were chronic opioid users after surgery. Adjusted rates of long-term opioid use were not different between groups when only accounting for prior opioid use but significantly higher for the high-intensity group when adjusting for surgical complications (OR=2.08; 95% CI 1.09-3.97). Of the entire cohort, 52.5% was still filling opioid prescriptions after 6 months.</p><p><strong>Conclusions: </strong>Higher-intensity procedures were associated with greater postoperative opioid use than lower-intensity procedures. Chronic opioid use was not significantly different between surgical intensity groups when considering only prior opioid use. Chronic opioid use was significantly higher among higher intensity procedures when accounting for surgical complications. The presence of surgical complications is a stronger predictor of postsurgical long-term opioid use in high-intensity surgeries than history of opioid use alone.</p><p><strong>Level of evidence: </strong>Level III.</p>","PeriodicalId":22193,"journal":{"name":"Spine","volume":" ","pages":"1607-1613"},"PeriodicalIF":2.6,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141331733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
