P-043: Mortality in very elderly patients admitted to an Intensive Care Unit: can we establish prognostic factors?

摘要

Introduction: The growth of the elderly population in many countries is associated with new medical and ethical challenges. The number of geriatric patients admitted to intensive care units is growing. However, the admission criteria, morbidity, mortality and prognostic factors are still under debate. Methods: We reviewed the medical records of patients aged > 85 years who were admitted in an Intensive Care Unit of a tertiary hospital. The admissions occurred from 2014 to 2018. The demographic and clinical characteristics and the mortality (in-hospital and 90 days- mortality) were recorded. A 95% confidence interval was used. Results: During a 5-year period, 101 patients aged ≥ 85 years were admitted to the Intensive Care Unit, with the eldest patient being 96 years-old. The majority of the patients were men (59% vs 41%). The medium length of stay was 11.2 days (sd ± 9.1). The most common reason for admission was a medical condition, followed by surgical and traumatic causes. During the ICU stay the mortality was 39%, however the 90 days mortality rate raised to 71%. All the patients were submitted to invasive mechanical ventilation, 83% required treatment with vasopressors and 16% of the patients needed dialytic therapy. The duration of mechanical ventilation, the use of vasopressors or dialysis were not found to be associated with in-hospital or 90 days mortality, in our group of patients. Conclusions: The admission of very elderly patients in Intensive Care Units is a reality. In our study, the ICU admission was associated with a high in-hospital mortality and even higher mortality after 90 days. Prognostic factors need to be established in order to improve decision-making processes at the time of admission.
