Abstract
BACKGROUND: An aging surgical population places an increasing burden on surgeons to accurately risk stratify and counsel patients. Preoperative frailty assessments are a promising new modality to better evaluate patients but can often be time consuming. Data regarding frailty and hepatectomy outcomes have not been published to date. METHOD: Using the National Surgical Quality Improvement Project database, we examined hepatectomy patients 2005 to 11 and correlated frailty scores with outcomes of major morbidity, mortality, and extended length of stay, using a previously validated modified frailty index score. Frailty was compared against age, American Society of Anesthesiologists class, and other common risk variables. RESULTS: Multivariate regression identified frailty as the strongest predictor of Clavien 4 complications (OR = 40.0, 95% CI = 15.2 to 105.0), and mortality (OR = 26.4, 95% CI = 7.7 to 88.2). As the frailty score increased, there was a statistically significant increase in Clavien 4 complications, mortality, and extended length of stay (P < .001 for all). CONCLUSIONS: Frailty is a significant factor in morbidity and mortality after hepatectomy. Use of the modified frailty index allows for feasibility of data collection in a busy clinical setting.
