RESUMEN
OBJECTIVE: We aimed to determine the proportion of elderly patients hospitalised for community-acquired pneumonia (CAP) in whom a 5-day antibiotic therapy would achieve clinical stability according to American Thoracic Society (ATS) criteria. METHODS: Patients aged≥75 years, hospitalised for CAP between November 2018 and August 2019, were analysed retrospectively. The American Thoracic Society (ATS) clinical stability criteria (temperature≤37°C, heart rate≤100/min, respiratory rate≤24/min, systolic blood pressure≥90mmHg, oxygen saturation≥90% in room air) were assessed after five days of antibiotic therapy. RESULTS: Seventy-five patients (mean age 88 years, 49% requiring oxygen therapy) were included. Six died, and at day 5, 36/69 (52%) fulfilled 4/5 stability criteria. The median duration of treatment was 9 days. In 28 patients (41%), it was ≤7 days. CONCLUSION: In 52% of elderly patients with CAP, a 5-day treatment regimen resulted in clinical stability.
