• W4386041703 abstract "BACKGROUND CONTEXT The Hospital Frailty Risk Score (HFRS) is a frailty-identifying metric developed using ICD-10-CM codes. While other studies have examined frailty in adult spinal deformity (ASD), the HFRS has not been assessed in this population. PURPOSE The aim of this study was to determine the impact of HFRS-defined frailty on outcomes in ASD patients undergoing posterior spinal fusion (PSF). STUDY DESIGN/SETTING Retrospective cohort study using the 2016-2019 National Inpatient Sample (NIS) database. PATIENT SAMPLE A total of 7,500 adult patients (≥18 years old) undergoing elective PSF for ASD. OUTCOME MEASURES Extended length of hospital stay (LOS), non-routine discharge disposition, increased costs of hospital admission. METHODS A retrospective study was performed using the 2016-2019 National Inpatient Sample database. Adults with ASD undergoing elective PSF were identified using ICD-10-CM codes. Patients were categorized into HFRS-based frailty cohorts: Low (HFRS<5) and Intermediate-High (HFRS≥5). Patient demographics, comorbidities, intraoperative variables, and outcomes were assessed. Multivariate regression analyses were used to determine whether HFRS independently predicted extended length of stay (LOS), non-routine discharge, and increased cost. RESULTS Of the 7,500 patients identified, 4,000 (53.3%) were in the Low HFRS cohort and 3,500 (46.7%) were in the Intermediate-High HFRS cohort. On average, age increased progressively with increasing HFRS scores (p<0.001). The frail cohort experienced more postoperative adverse events (p<0.001), greater LOS (p<0.001), accrued greater admission costs (p<0.001), and had a higher rate of non-routine discharge (p<0.001). On multivariate analysis, Intermediate-High HFRS was independently associated with extended LOS (OR: 2.58, p<0.001) and non-routine discharge (OR: 1.63, p<0.001), though not increased admission cost (OR: 1.01, p=0.929). CONCLUSIONS This study is the first to use the HFRS to assess the impact of frailty on perioperative outcomes in patients with ASD. Among patients with ASD, HFRS-defined frailty was associated with longer hospitalizations, non-routine discharge, and higher costs.
