Clinical features and disease progression of elderly patients at the ICU setting.
Medicina intensiva. 2024 March 22
OBJECTIVE: To describe and characterize a cohort of octogenarian patients admitted to the ICU of the University Central Hospital of Asturias (HUCA).
DESIGN: Retrospective, observational and descriptive study of 14 months' duration.
SETTING: Cardiac and Medical intensive care units (ICU) of the HUCA (Oviedo).
PARTICIPANTS: Patients over 80 years old who were admitted to the ICU for more than 24 h.
INTERVENTIONS: None.
MAIN VARIABLES OF INTEREST: Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality.
RESULTS: The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p = 0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p = <0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR = 0,18; 95% CI (0,062-0,527; p = 0,002).
CONCLUSIONS: The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty.
