STUDY DESIGN.: Retrospective review of a prospective multicenter database. OBJECTIVE.: Identify variables associated with extended length of stay (ExtLOS) and this impact on health related quality of life (HRQoL) scores in adult spinal deformity (ASD) patients. SUMMARY OF BACKGROUND DATA.: ASD surgery is complex and associated with complications including extLOS. Though variables contributing to extLOS have been considered, specific complications and pre-disposing factors among ASD surgical patients remain to be investigated. METHODS.: Inclusion criteria: ASD surgical patients (age>18yrs, scoliosis≥20°, SVA≥5?cm, PT≥25° and/or TK>60°) with complete demographic, radiographic and HRQoL data at baseline, 6 weeks, and 2 years post-operative. ExtLOS was based on 75 percentile (≥9 days). Univariate and multivariate analyses identified predictors and evaluated effects on outcomes. Repeated measures mixed models analyzed impact of ExtLOS on HRQoL (ODI; SF-36?PCS/MCS; SRS22r Activity (AC), Pain (P), Appearance (AP), Satisfaction (S), Mental (M) and Total (T)). RESULTS.: 380 patients met inclusion criteria: 105 (27.6%) had extLOS (≥9 days), 275 (72.4%) did not. Average LOS was 8 days (range: 1–30 days). Age (OR 1.04), # levels fused (OR 1.12), # infections (OR 2.29), # neurologic complications (OR 2.51), Charlson Comorbidity Index Score (CCI) predicted ExtLOS (OR 3.92), and # intra-op complications predicted ExtLOS (OR 3.56). ExtLOS patients had more intra cardiopulmonary (pleural effusion: 1.9% vs. 0%), and operative complications (dural tear: 13.3% vs. 5.1%; excessive blood loss: 18% vs. 5.8%) (p?
