Hypoalbuminemia at admission is associated with increased incidence of in-hospital complications in geriatric trauma patients

BACKGROUND: Elderly patients are at an increased risk of protein-energy malnutrition (PEM) which increases the risk of morbidity/mortality. We evaluated the association between hypoalbuminemia at the time of emergency department (ED) admission and in-hospital complications among geriatric trauma patients. METHODS: This was an ambidirectional cohort study of geriatric (>= 55 years) trauma patients treated at a Level I trauma center between May 2013 and March 2014. The exposure of interest was albumin level at ED admission (<3.6 g/dL [PEM] or >= 3.6 g/dL (No PEM)]. The outcome of interest was 30-day incidence of complications. RESULTS: A total of 130 patients met study eligibility. Of these, 85 (65%) patients were in the PEM group. After adjusting for tube feeding and injury severity score, PEM at admission was associated with a 2-fold increase in the risk of 30-day overall hospital complications (hazard ratio 2.1, 95% confidence interval 1.1 to 3.8). CONCLUSION: Serum albumin level at ED admission, but not prealbumin level, is a significant predictor of in-hospital complications in geriatric trauma patients. (C) 2015 Elsevier Inc.
