- Background: The purpose of this study was to evaluate the long-term survival rates of very elderly (age A >= 80) critically ill patients admitted to a medical intensive care unit (MICU) at a regional tertiary-care hospital in Korea. Methods: We retrospectively analyzed data from patients who survived after discharged from the MICU of our hospital. Survival rates at 90 days, 1 year, 2 years, and 3 years were assessed between patients age A >= 80 and those age <80. Survival status was evaluated using the National Health Insurance Service data. Results: A total of 468 patients were admitted, 286 (179 males, 97 females; mean age, 70.18 +/- 13.2) of whom survived and were discharged soon after their treatment. Among these patients, 69 (24.1%) were age A >= 80 and 217 (75.9%) were age <80. The 90-day, 1-year, 2-year, and 3-year survival rates of patients age A >= 80 were significantly lower than those in patients age <80 (50.7%, 31.9%, 15.9% and 14.5% vs. 68.3%, 54.4%, 45.6%, and 40.1%, respectively) (p<0.01). The Kaplan-Meier survival curves showed significantly lower survival rates in patients age A >= 80 than in those age <80 (p=0.001). Conclusion: The poor rates of long-term survival in very elderly (age A >= 80) and critically ill patients admitted to an ICU should be considered while managing and treating them.
