• A retrospective study of 402 critically ill adults aged 70 and over found that the Clinical Frailty Scale (CFS) score is a strong predictor of mortality.
• Higher CFS scores, indicating greater frailty, were significantly associated with increased risk of short-term (30-day), mid-term (1-year), and long-term (6.5-7.5 years) mortality.
• The CFS demonstrates potential as a valuable tool for risk stratification and prognostication in elderly patients admitted to the emergency department.
• Findings highlight the importance of frailty assessment in managing critically ill older adults to improve outcomes and tailor treatment strategies.
