RESUMO
The current growth of the geriatric population and increased burden on trauma services throughout the United States (US) has created a need for systems that can improve patient care and reduce hospital costs. We hypothesize that the multidisciplinary services provided through the Geriatric Injury Institute (GII) can reduce hospital costs, improve patient triage throughput, and decrease hospital length of stay (LOS). METHODS AND MATERIAL: We performed a single-center, retrospective chart review of our Level II trauma center registry and electronic medical records of patients ages 65 and older who satisfied trauma activation/code criteria between July 1, 2014, to June 30, 2016 (N = 663). Patients presenting from July 1, 2014, to June 30, 2015, were grouped as Pre-GII, while those presenting from July 1, 2015, to June 30, 2016, were grouped as Post-GII. Primary outcomes were emergency department (ED) triage time, overall LOS, and hospital costs. Secondary outcomes included patient disposition, mortality, and health assessments. Statistical comparisons were made using a one-way analysis of variance and Mann-Whitney U test. RESULTS: Pre-GII vs. Post-GII average ages and the Injury Severity Score (ISS) were not statistically different (p>0.05). The average LOS was similar between the Pre-GII and Post-GII groups (4.64 ± 4.42 days vs. 4.26 ± 5.58 days, p = 0.48). More patients were discharged earlier (≤ 4 days; 64% vs. 73%) as well as discharged to home (37% vs. 45%) in the Post-GII group. The total cost savings were $53,000 with a median savings of $1061 per patient ($8808 vs. $7747, p = 0.04). Savings were highest during the first two days of admission (p = 0.03). The reduction in ED triage time was not significant (310.7 minutes vs 219. 8 minutes, p > 0.05). CONCLUSION: With the increase in geriatric trauma, innovative models of care are needed. Our study suggests that the GII multidisciplinary approach to trauma services can lower overall hospital costs.
