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. e primary outcome studied was in-hospital mortality. e 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)). e ICU length of stay was increased by 0.91 days or 19.03% (p value � 0.016 (95% CI 0.167–1.655)). ere 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. is 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. 1. Background 1.1. Trauma, Trauma Centers, and the Early Years of the Montreal General Hospital Trauma Program. Trauma is the leading cause of death between the ages of 1 and 46 in the USA as well as the leading cause of years of life lost [1]—a trend that has not changed in over 20 years. In Canada, preventable injuries reflect the same reality. Every day, it is estimated that roughly 10,000 Canadians are injured and require medical attention. After assessment in the emer- gency department, 6% of those daily injured patients will be admitted to the hospital, 1.6% are left with disabling mor- bidity, and 0.4% will die [2]. Faced with the important mortality and morbidity associated with trauma in Canada, it is understandably crucial to continue improving the care of trauma patients. e aim of this article is therefore to assess the impact of the Trauma Team Leader (TTL) pro- gram by comparing the time period before and after its implementation at the Montreal General Hospital (MGH) as well as providing a possible explanation to the success of this paradigm in the hopes that other institutions may benefit from our experience over the years. e implementation of a regionalized trauma system in the province of Quebec started in the early 1990s. At that time, the need to improve trauma care had become well recognized at the governmental level. A study performed before the implementation of trauma centers showed that trauma patients had an increased mortality compared to the results of the Major Trauma Outcome Study [3].
