BackgroundThe global population is aging, and the proportion of elderly patients admitted to Intensive Care Units (ICUs) is increasing. In this scenario, achieving a balance between judicious utilization of a limited and high-cost resource and providing optimal intensity of care presents a challenge, given that in very elderly patients, the value of ICU care is uncertain. The aim of our study is to evaluate the survival of older patients admitted to ICU who require mechanical ventilation (MV) at different levels of treatment intensity.MethodsA comprehensive longitudinal ICU database was retrospectively analyzed at a single tertiary center, from January 2008 to December 2014, of ICU subjects 80 years old or older who required mechanical ventilation.ResultsFrom January 2009 to December 2014, 482 subjects were admitted to the ICU and required mechanical ventilation. Among them, 376 (78%) were aged between 80 to 89 years, and 106 (22%) were aged 90 years or older, with a mean age of 85.84 (4.56). The mean APACHE II score was 21.53 (7.42), and the mean SOFA score was 5.75 (3.38). The total mortality during ICU admission was 46%, and the hospital mortality was 58%. Only age higher than 90 years (1.41(1.05;1.91), P = .02) and APACHE score (1.03(1.01;1.05), P < .001) were associated with mortality after adjustments. The TISS score was analyzed in tertiles and was not related to mortality in univariate analysis or after adjustments.ConclusionsOur data indicate that in older subjects using MV, higher intensity of treatment does not seem to translate into a survival benefit. This finding highlights the importance of considering individualized treatment plans for elderly patients in the ICU.Copyright © 2024 by Daedalus Enterprises.
