A cross-sectional study in Buenos Aires in 2010 examined 66 elderly patients hospitalized for pneumonia, finding an average age of 82, with 54.5% being male.
Nearly half (47.0%) were hospitalized for community-acquired pneumonia, and a significant portion showed dependence in daily living activities, highlighting the functional challenges faced by these patients.
The study reported a 28.8% mortality rate overall, which increased to nearly 50% in patients with confusional syndrome, indicating the severe impact of pneumonia in the elderly population and the importance of tailored diagnosis and evaluation.
