Abstract
Background: Determine effects of pre-operative opiate use on anterior cervical discectomy and fusion (ACDF) surgery outcomes. Methods: The study design was a single center retrospective cohort study. Patient records were reviewed from 2013 and 2018 for elective 1 to 2 level ACDF surgeries. Patients were classified as: opiate naive (ON: no history of opiate) use, acute opiate (AO: <6 months preoperatively) use, and chronic opiate (CO: 6-12 months preoperatively) use based on prescription history before surgery. Opiate use was quantified by milligram morphine equivalents (MME) at 6-12 months preop, 0-6 months preop, 0-6 months postop, and 6-12 months postop. Charts were reviewed for American Society of Anesthesiologists (ASA) physical status classification and smoking history. Results: Readmission rates were 9.8% for ON, 9.1% for AO, and 30% for CO (P value <0.05). Average opiate use measured in MME 6-12 months post-surgery was 5.76 for ON, 18.44 for AO, and 39.92 for CO (P value <0.05). Readmission rate between nonsmokers, former smokers, and active smokers was 4.4%, 0%, and 10.8% (P value <0.05) at 30-90 days post-surgery, and 1.1%, 14.5%, and 2.5% (P value <0.05) in the 91 days to 1-year post-surgery. Conclusions: There is statistically significant relationship between CO and higher readmission rates after ACDF. Preoperative opiate use is also associated with increased opiate use 6-12 months after surgery. Smoking history is also associated with increased readmission rates. 2022 Journal of Spine Surgery.
