Early and late hospital readmissions in adolescent idiopathic scoliosis.

Abstract

Retrospective review of a prospectively collected multicenter database. To identify risk factors for early and late readmission of surgically treated patients with adolescent idiopathic scoliosis (AIS). Specific risk factors associated with readmission in patients with AIS remain poorly understood. Patients with AIS who were operatively treated from 19 centers specializing in the treatment of pediatric spinal deformity were studied. Data from a minimum 2years of clinical follow-up and any readmission were available for analysis. Characteristics of patients with no readmission, early readmission (< 90days), and late readmission (> 90days) were evaluated. Both univariate and multivariate analyses of risk factors for readmission were performed. 2049 patients were included in our cohort, with 1.6% requiring early readmission and 3.3% late readmission. In the multivariate analysis, greater preoperative coronal imbalance was associated with early readmission. Longer operative time was associated with late readmission. Finally, greater preoperative pain (SRS-22 pain scale) was associated with both early and late readmission. GI complications accounted for a higher proportion of early readmissions than previously reported in the literature. Preoperative counseling of patients with higher levels of pain and coronal imbalance and the implementation of a thorough postoperative bowel regimen may help optimize patient outcomes. 3.
