Abstract

Objective: The aim of this study was to determine the impact of preoperative pulmonary risk factors (PRFS) on surgical outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). Methods: A retrospective cohort study was performed using the American College of Surgeons National Surgical Quality Improvement Program–Pediatric database from 2016 to 2018. All pediatric patients with AIS undergoing PSF were identified. Patients were then categorized by whether they had recorded baseline PRF or no-PRF. Patient demographics, comorbidities, intraoperative variables, complications, length of stay, discharge disposition, and readmission rate were assessed. Results: A total of 4929 patients were identified, of whom 280 (5.7%) had baseline PRF. Compared with the no-PRF cohort, the PRF cohort had higher rates of complications (PRF, 4.3% vs. no-PRF, 2.2%; P = 0.03) and longer hospital stays (PRF, 4.6 ± 4.3 days vs. no-PRF, 3.8 ± 2.3 days; P < 0.001), yet, discharge disposition was similar between cohorts (P = 0.70). Rates of 30-day unplanned readmission were significantly higher in the PRF cohort (PRF, 6.3% vs. no-PRF, 2.7%; P = 0.009), yet, days to readmission (P = 0.76) and rates of 30-day reoperation (P = 0.16) were similar between cohorts. On multivariate analysis, PRF was found to be a significant independent risk factor for longer hospital stays (risk ratio, 0.74; 95% confidence interval, 0.44–1.04; P < 0.001) but not postoperative complication or 30-day unplanned readmission. Conclusions: Our study showed that PRF may be a risk factor for slightly longer hospital stays without higher rates of complication or unplanned readmission for patients with AIS undergoing PSF and thus should not preclude surgical management.
