Abstract
BACKGROUND: To illustrate the impact of the implementation of a multidisciplinary TTL program in 2005 on the mortality of trauma patients in a level 1 trauma center as well as admission rates and length of stay. METHODS: Retrospective observational study of all trauma patients included in the provincial trauma database at the Montreal General Hospital between 1998 and 2015. The primary outcome studied was in-hospital mortality. The secondary outcomes studied were hospital and intensive care unit (ICU) rates of admission and hospital and ICU length of stay. RESULTS: 24,107 patients were included. We observed a statistically significant reduction in mortality of 1.25% or a relative reduction of 16% (p value = 0.0058; rate ratio 0.844 (95% CI 0.747-0.952)). ICU admissions were also significantly reduced where we observed a statistically significant absolute reduction of 4.46% or a relative reduction of 14% (p value = 8.38 × 10(-7); rate ratio 0.859 (95% CI 0.808-0.912)). The ICU length of stay was increased by 0.91 days or 19.03% (p value = 0.016 (95% CI 0.167-1.655)). There was no observed change in overall length of stay (13.97 days pre-TTL and 12.91 post-TTL (p value = 0.13; estimate -1.053 (95% CI -2.424-0.318))). CONCLUSIONS: This article suggests that multidisciplinary TTL model may be beneficial in the care of trauma patients. Further subgroup analysis may help determine which patients could benefit more.
