Abstract 16763: Frailty, as Measured by the Essential Frailty Toolset, is Associated With Higher Resource Utilization in Patients Undergoing Coronary Artery Bypass Grafting

Introduction: Frailty is an important predictor of clinical outcomes, but its contribution to resource utilization remains understudied. This study investigates the impact of frailty on high resource utilization (HRU) in patients undergoing Coronary Artery Bypass Graft Surgery (CABG). Methods: We reviewed data on patients who underwent CABG at a single center between 04/2018 and 12/2019. A Frailty score (FS) was calculated using the Essential Frailty Toolset (EFT). Patients were divided into two groups: Frail (FS ≥ 3/5) & Non-Frail (FS 7 days or readmission within 30-days). Secondary outcomes included operative time, prolonged ventilation, & direct procedure costs. Multivariable logistic regression was used to assess the effect of frailty on HRU. Results: The study included 740 patients of whom 18% (n=132) were frail. Compared to Non-Frail patients, Frail patients were older (66 vs. 70 yrs. P Conclusions: About one out of every five patients undergoing CABG was classified as frail by the EFT. Frailty was associated with higher direct costs and found to be an independent predictor of high resource utilization. Further attention is required to optimize outcomes and resource use in this vulnerable population.
