We examined the relationship between trauma related mortality and morbidity and EMS response time. Methods: Retrospective cohort study of paediatric patients under the age of 18 who suffered a traumatic injury and were attended to by EMS in Calgary and Edmonton, Alberta between April 2010 and September 2013 Results: The adjusted risk ratio of mortality given a response time of ≥8 minutes is 0.635 times that of a response time <8 minutes (95% CI: 0.346-1.166; p=0.143). The adjusted risk ratio of admission to hospital given a response time of >8 minutes is 1.165 times that of a response time <8 minutes (95% CI: 0.985-1.379; p=0.075). Conclusions: The eight minute response time was not associated with a difference in all cause mortality or admission to hospital.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
