Abstract
BACKGROUND: The aim of our study was to assess the association between frailty and functional status in geriatric trauma patients. METHODS: 3-year(2013-2015) prospective analysis and included all geriatric trauma patients(≥65y) discharged to a single rehabilitation center from our level-I trauma center. Frailty was measured using Trauma-Specific-Frailty-Index(TSFI) while Functional status was assessed using functional-independence-measure(FIM) at admission and discharge from rehabilitation center. Multivariate linear regression analysis was performed. RESULTS: 267 patients were enrolled. Mean age was 76.9 ± 7.1y, 63.6% were males. Overall, 22.8% were frail, and 37.4% were pre-frail. On linear regression, higher motor-FIM, higher cognitive-FIM scores at admission, and longer length-of-stay at rehab were independently associated with increased discharge FIM score. While, ISS(injury-severity-score), pre-frail and frail status were negatively correlated with FIM gain. CONCLUSION: Frail patients were less likely to recover to their baseline functional status compared with non-frail patients. Early focused intervention in frail elderly patients is warranted to improve functional status in this population.
