Abstract

Introduction: Older adult individuals often have acute illnesses predisposing them to developing acute respiratory distress syndrome (ARDS). We aimed to identify the relationship between age and the development of ARDS in a cohort of hospitalized patients. Methods: This was a secondary analysis of a prospective multicenter observational cohort study of hospitalized patients at risk of developing ARDS admitted to 22 hospitals from March 2009 to August 2009. Patients were classified as older adults if their age was 80 or greater. A multivariable logistic regression was performed, adjusting for severity of illness via Acute Physiology and Chronic Health Evaluation (APACHE II) and risk of ARDS via Lung Injury Prediction Score. Results: Of 5584 patients, 377 (6.8%) developed ARDS. Twenty-four (3.5%) of 694 patients aged 80 or older developed ARDS, compared to 353 (7.2%) of 4890 patients aged less than 80 (P <.001). After adjusting for severity of illness and the risk of ARDS development, older adult patients had a lower incidence of ARDS compared to younger individuals (odds ratio: 0.28, 95% confidence interval: 0.18-0.42). Conclusion: Older adult patients aged 80 years or older have a reduced incidence of ARDS compared to younger patients, after adjusting for severity of illness and risk of ARDS development.
