Study design: Retrospective cohort study.
Objective: To determine hospital length of stay (LOS) and long-term opioid consumption among patients who received inpatient multimodal analgesia following lumbar spine surgery, as opposed to those who received opioids alone.
Summary of background data: Opioids have long been the historical choice for managing postoperative pain. The use of multimodal analgesia has become more commonplace in recent years as it is thought to achieve similar levels of pain control while simultaneously diminishing opioid consumption and decreasing LOS.
Materials and methods: Patients who underwent 1 or 2-level lumbar fusion from 2018 to 2019 were included. Patients who received opioids on an as-needed basis were propensity-matched to a cohort who received multimodal analgesia based on demographics, surgical approach, and levels fused. LOS was collected for each patient. One year preoperative to 2 postoperative opioid use was obtained from the Pennsylvania Prescription Drug Monitoring Program and included total prescriptions and total morphine milligram equivalents (MMEs). A subanalysis was also performed comparing preoperative, perioperative, and postoperative tramadol consumption during this time frame.
Results: A total of 69 patients received an opioid-only pain regimen, while 207 patients received multimodal analgesia. Patients receiving a multimodal pain regimen consumed a higher daily tramadol MME but a comparable total in-hospital MME to patients in the opioid-only cohort. No statistically significant differences existed between cohorts with regards to LOS, preoperative, perioperative, and postoperative opioid consumption, though multimodal patients consumed more tramadol from 0 to 30 days postoperatively.
Conclusions: Patients who received a multimodal pain regimen consumed comparable quantities of opioids to those who received opioids alone and did not have a longer LOS following 1 and 2-level lumbar fusion.
