BackgroundAs our population ages, older adults are increasingly exposed to trauma. Frailty could be a useful measure to identify patients at risk of a poor outcome. This study aimed to determine the impact of frailty in an Australian trauma intensive care unit (ICU) population.MethodsA prospective observational study of critically ill trauma patients ≥50 years of age. Frailty was determined on admission to the ICU using the frailty phenotype. Demographic and hospital data were collected, and patients were followed up at 6 and 12 months. The primary outcome was 12-month mortality, and multiple regression was used to determine associated factors.ResultsOne hundred thirty-eight patients were included, whose mean age was 68 years; 78.2% (108/138) were classified as major trauma (Injury Severity Score >12). Twenty-two percent (30/138) of patients were identified as frail. Patients with frailty were significantly older: however, they were less severely injured and required lower rates of surgical interventions and mechanical ventilation. Frailty was independently associated with mortality at 6 and 12 months (odds ratio: 5.9, 95% confidence interval: 1.9-18.1 and odds ratio: 7.3, 95% confidence interval: 2.5-21.9, respectively). Patients with frailty had lower measures of global functioning (Glasgow Outcome Scale-Extended frail 3 [1-5] vs nonfrail 6 [(5-7], p = 0.002) and health status (Euro Qol 5Q-5D-5L utility score 0.6 [0.5-0.7] vs 0.7 [0.6-0.9], p = 0.02) at 12 months than patients without frailty.ConclusionFrailty is a useful predictor of poor outcomes in critically ill trauma patients.Registration Of Protocol NumberACTRN12615000039583.Copyright © 2019 Australian College of Critical Care Nurses Ltd.
