Compared and validated a frailty index to existing risk stratification tools for urologic surgery.
Examined whether our modified frailty index was predictive of death and complications.
Increasingly frailty patients with high frailty index scores have adverse outcomes.
Combining the ASA Risk Class and our modified frailty index was the best predictor of adverse events
A modified frailty index may help risk stratify patients who are not good surgical candidates.
