AB  - Background Approximately 50% of patients with congenital scoliosis will require surgical treatment to prevent further progression. Outcomes following congenital scoliosis are sparse in the literature. The purpose of this study was to identify independent risk factors associated with unplanned readmission and prolonged length of stay (LOS) in patients undergoing primary surgical treatment for congenital scoliosis.Methods The National Surgical Quality Improvement Database-Pediatric was queried for database years 2016–2018 to identify patients with congenital scoliosis who underwent primary posterior fusion of the spine. Patient demographics, comorbidities, and operative variables, such as the number of levels fused and the American Society of Anesthesiologists (ASA) classificaiton, were collected. Univariate and multivariate analyses of patient factors were performed to test for association with readmission within 30 days and prolonged LOS (>4 days).Results Eight hundred sixteen patients were identified. The average age was 11.3 ± 4.02 years, and the mean postoperative LOS was 4.64 ± 3.71 days. Forty-three patients (5.40%) were readmitted, and 73 patients (8.96%) had prolonged LOS. Independent risk factors associated with prolonged LOS included chronic lung disease (P < 0.001), presence of a tracheostomy (P < 0.001), structural central nervous system abnormality (P = 0.039), oxygen support (P < 0.001), and number of levels fused (P = 0.008). The factors independently associated with unplanned readmission were fusion to the pelvis (P = 0.004) and LOS >4 days (P = 0.008).Conclusions Prolonged LOS and readmission are widely being used as quality and performance metrics for hospitals. Congenital scoliosis, which often progresses rapidly resulting in significant deformity, frequently requires surgery at an earlier age than idiopathic and neuromuscular deformity. Nevertheless, 30-day outcomes for surgical intervention have not been thoroughly studied. The present study identifies risk factors for prolonged LOS and readmission, which can facilitate preoperative planning, patient/family counseling, and postoperative care.Clinical Relevance Congenital scoliosis management poses certain challenges that may be mitigated by understanding the risk factors for adverse outcomes following primary fusion surgery.
