Purpose: The aim of this study was to identify factors associated with the outpatient narcotic intake of patients following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) and to introduce a safe and effective method of disposing of unused narcotics.
Methods: Following Institutional Review Board approval, retrospective review of prospectively collected data from patients undergoing PSF for AIS took place. Pain scores, narcotic use, patient demographic data, pre-, intra-, and postoperative parameters, and discharge data were gathered via chart review. Patients were divided into two groups according to home narcotic use, high use (top 25th percentiles) and low use (bottom 75th percentiles), and multivariate statistical analysis was conducted. Narcotic surplus was collected during postoperative clinic visits and disposed of using biodegradable bags.
Results: Statistical analysis of 27 patients included in the study showed that patients with a higher home narcotic use correlated with increased length of hospitalization with an average of 3.4 days compared to the lower-use group of 2.8 day (p = 0.03). Higher-use group also showed increased inpatient morphine milligram equivalent than the lower-use group. There was no significant difference of home narcotic use when looking at patient age, height, weight, BMI, levels fused, intraoperative blood loss, or length of surgery. A total of 502 narcotic doses were disposed of in the clinic.
Conclusion: Our study suggests that there are not a significant number of patient- or surgical-level factors predisposing patients to increased home narcotic usage following spinal fusion for adolescent idiopathic scoliosis.
Level of evidence: Level I, prospective study.
