Key result
Older age (≥65 years) was associated with higher 1-year mortality (43.1%) compared to younger patients (10.6%), with chronic conditions also significantly influencing survival.

What are the prognostic factors for ICU and 1-year mortality in adult intensive care patients?
Absolute Event Rate: 43.1% vs 10.6%
Age and chronic illnesses such as diabetes, heart failure, and cancer are significant prognostic factors for 1-year mortality in ICU patients.
Zarén et al. (1988) conducted a cohort in Intensive care admission (n=978). Age ≥65 years vs. Age 15-44 years was evaluated on 1-year cumulative mortality. Older age (≥65 years) was associated with higher 1-year mortality (43.1%) compared to younger patients (10.6%), with chronic conditions also significantly influencing survival.
