Association of ICU Admission Time, Age Stratification, and Clinical Frailty Scale With 30-Day Mortality in Geriatric Oncology Patients

Geriatric oncology patients frequently require intensive care admission and are at increased risk of adverse outcomes due to advanced age, frailty, and critical illness. Delays in admission from the emergency department to the intensive care unit (ICU) may further contribute to poor prognosis. This retrospective cohort study aims to evaluate the association of ICU admission time, age stratification, and Clinical Frailty Scale (CFS) score with 30-day mortality among geriatric cancer patients admitted from the emergency department to the Anesthesiology and Reanimation Intensive Care Unit. Secondary objectives include assessing the relationship of these factors with intensive care unit length of stay, hospital length of stay, and in-hospital mortality. The findings may contribute to improved risk stratification and optimization of critical care management in geriatric oncology patients.
