Study DesignRetrospective matched case cohort.ObjectiveCompare postoperative opioid utilization and prescribing behaviors between patients with Marfan syndrome (MFS) and adolescent idiopathic scoliosis (AIS) after posterior spinal fusion (PSF).Summary Of Background DataOpioids are an essential component of pain management after PSF. However, due to the potential for opioid use disorder and dependence, current analgesic strategies aim to minimize their use, especially in younger patients. Limited information exists on opioid utilization after PSF for syndromic scoliosis.Patients And MethodsTwenty adolescents undergoing PSF with MFS were matched with patients with AIS (ratio, 1:2) by age, sex, degree of spinal deformity, and the number of vertebral levels fused. Inpatient and outpatient pharmaceutical data were reviewed for the quantity and duration of opioid and adjunct medications. Prescriptions were converted to morphine milligram equivalents (MMEs) using CDC's standard conversion factor.ResultsCompared with patients with AIS, patients with MFS had significantly greater total inpatient MME use (4.9 vs . 2.1 mg/kg, P ≤ 0.001) and longer duration of intravenous patient-controlled anesthesia (3.4 vs . 2.5 d, P = 0.001). Within the first 2 postop days, MFS patients had more patient-controlled anesthesia boluses (91 vs . 52 boluses, P = 0.01) despite similar pain scores and greater use of adjunct medications. After accounting for prior opioid use, MFS was the only significant predictor of requesting an opioid prescription after discharge (odds ratio: 4.1, 95% CI: 1.1-14.9, P = 0.03). Patients with MFS were also more likely to be discharged with a more potent prescription (1.0 vs . 0.72 MME per day/kg, P ≤ 0.001) and to receive a longer-duration prescription (13 vs . 8 d, P = 0.005) with a greater MME/kg (11.6 vs . 5.6 mg/kg, P ≤ 0.001) as outpatients.ConclusionDespite a similar intervention, patients with MFS and AIS seem to differ in their postoperative opioid usage after PSF, presenting an opportunity for further research to assist clinicians in better anticipating the analgesic needs of individual patients, particularly in light of the ongoing opioid epidemic.Copyright © 2023 Wolters Kluwer Health, Inc.
