Context: Opioids may be prescribed for the short-term management of acute-onset back pain in the setting of trauma or for long-term management of chronic back pain. More than 50% of regular opioid users report taking them for back pain.
Objective: To investigate whether surgical intervention reduces opioid requirements by patients taking opioids for back pain and whether there is a difference between county and managed care hospitals in this postoperative reduction of opioid requirement.
Methods: A retrospective medical record review of 118 patients who underwent elective lumbar fusion at 4 hospitals (2 county hospitals and 2 managed care hospitals) was conducted. Opioid requirements before and after surgical intervention and at the 30-day outpatient follow-up were evaluated.
Results: Forty medical records were included in the study. An overall decrease in opioid use was found in the postoperative follow-up phase after lumbar fusion in both the county and managed care hospitals. This reduction was statistically significant at 3 of 4 hospitals (P<0.01). When the data were pooled by facility type, the significance remained for county facilities (P<.01) but not managed care facilities (P=.18). Moreover, there was a significant decrease in opioid use during the postoperative inpatient phase for county compared with managed care facilities (P=.0427). The pain rating reported by patients during the hospital stay was significantly higher at county compared with managed care hospitals (P=.0088); however, the difference at discharge was not significant (P=.14).
Conclusion: Our study indicates that lumbar fusion is associated with a significant decrease in opioid use (P<.05) compared with nonsurgical management. Overall, the difference in decreased opioid use between county and managed care hospitals after lumbar fusion was not significant.
