Abstract

Although spine procedures have historically been performed inpatient, there has been a recent shift to the outpatient setting for selected cases due to increased patient satisfaction and reduced cost. Effective postoperative pain management while limiting over-prescribing of opioids, which may lead to persistent opioid use, is critical to performing spine surgery in the outpatient setting.To assess if there is an increased risk for new, persistent opioid use between inpatient and outpatient spine procedures.Retrospective analysis using national administrative claims database.390,049 opioid-naïve patients with a perioperative opioid prescription who underwent an inpatient or outpatient spine surgery.Patients with perioperative opioid prescriptions who filled = 1 opioid prescription between 90- and 180-days following surgery were defined as new, persistent opioid users.We utilized a claims database to identify opioid-naïve patients who underwent lumbar or cervical fusion, total disc arthroplasty, or decompression procedures. We constructed a multivariable logistic regression to evaluate the association between inpatient versus outpatient surgery and the development of new, persistent opioid use while adjusting for several patient factors.19,205 (11.7%) inpatient and 18,546 (8.2%) outpatient patients developed new, persistent opioid use. Outpatient lumbar and cervical spine surgery patients were significantly less likely to develop new, persistent opioid use following surgery compared to inpatient spine surgery patients (OR?=?0.71 [95% confidence interval (CI): 0.69, 0.73], p < 0.001). Average morphine milligram equivalents (MMEs) (inpatient?=?1,476 MME +/- 22.7, outpatient?=?1,072 MME +/- 18.5, p < 0.001) and average MMEs per day (inpatient?=?91.6 MME +/- 0.32, outpatient?=?77.7 MME +/- 0.28, p < 0.001) were lower in the outpatient cohort compared to the inpatient.Our results support the shift from inpatient to outpatient spine procedures, as outpatient procedures were not associated with an increased risk for new, persistent opioid use. As more patients become candidates for outpatient spine surgery, predictors of new, persistent opioid use should be considered during risk stratification.Level III Prognostic Study.We utilized a national administrative claims database to identify opioid-naïve patients who underwent common spine procedures. Outpatient lumbar and cervical spine surgery patients were significantly less likely to be new, persistent opioid users following surgery compared to inpatient spine surgery patients. Our results support the shift to outpatient spine procedures.
