This retrospective cohort study compared the filling rate, amount, and type of opioid prescriptions following ambulatory and inpatient single-level ACDF. The study found a slightly higher filling rate for opioid prescriptions after ambulatory ACDF compared to inpatient procedures, but no significant differences in prescription amount and type. There was no association between surgical setting and persistent opioid use. These findings are important for patient counseling and support the safety of ambulatory ACDF.
BACKGROUND CONTEXT: Opioid utilization has been well studied for inpatient anterior cervical discectomy and fusion (ACDF). However, the amount and type of opioids prescribed following ambulatory ACDF and the associated risk of persistent use are largely unknown. PURPOSE: To characterize opioid prescription filling following single-level ambulatory ACDF compared with inpatient procedures. STUDY DESIGN/SETTING: Retrospective cohort study. PATIENT SAMPLE: Opioid-naive patients who underwent ambulatory (no overnight stay) or inpatient single-level ACDF from 2011 to 2019 were identified from a national insurance database. OUTCOME MEASURES: Rate, amount, and type of perioperative opioid prescription. METHODS: Opioid-naive patients who underwent ambulatory (no overnight stay) or inpatient single-level ACDF from 2011 to 2019 were identified from a national insurance database. Perioperative opioids were defined as opioid prescriptions 30 days before and 14 days after the procedure. Rate, amount, and type of opioid prescription were characterized. Multivariable analyses controlling for any differences in demographics and comorbidities between the two treatment groups were utilized to determine any association between surgical setting and persistent opioid use (defined as the patient still filling new opioid prescriptions > 90 days postoperatively). RESULTS: A total of 42,521 opioid-naive patients were identified, of which 2,850 were ambulatory and 39,671 were inpatient. Ambulatory ACDF was associated with slightly increased perioperative opioid prescription filling (52.7% vs 47.3% for inpatient procedures; p<. 001). Among the 20,280 patients (47.7%) who filled perioperative opioid prescriptions, the average amount of opioids prescribed (in morphine milligram equivalents) was similar between ambulatory and inpatient procedures (550 vs 540, p=.413). There was no association between surgical setting and persistent opioid use in patients who filled a perioperative opioid prescription, even after controlling for comorbidities, (adjusted odds ratio, 1.15, p=.066). CONCLUSIONS: Ambulatory ACDF patients who filled perioperative opioid prescriptions were prescribed a similar amount of opioids as those undergoing inpatient procedures. Further, ambulatory ACDF does not appear to be a risk factor for persistent opioid use. These findings are important for patient counseling as well as support the safety profile of this new surgical pathway. (c) 2022 Elsevier Inc. All rights reserved.
