Objectives
As Canada’s second largest province, the geography of Quebec poses unique challenges for trauma management. Our primary objective was to compare mortality rates between trauma patients treated at rural emergency departments (EDs) and urban trauma centres in Quebec. As a secondary objective, we compared the availability of trauma care resources and services between these two settings.
Design
Retrospective cohort study.
Setting
26 rural EDs and 33 level 1 and 2 urban trauma centres in Quebec, Canada.
Participants
79 957 trauma cases collected from Quebec’s trauma registry.
Primary and secondary outcome measures
Our primary outcome measure was mortality (prehospital, ED, in-hospital). Secondary outcome measures were the availability of trauma-related services and staff specialties at rural and urban facilities. Multivariable generalised linear mixed models were used to determine the relationship between the primary facility and mortality.
Results
Overall, 7215 (9.0%) trauma patients were treated in a rural ED and 72 742 (91.0%) received treatment at an urban centre. Mortality rates were higher in rural EDs compared with urban trauma centres (13.3% vs 7.9%, p<0.001). After controlling for available potential confounders, the odds of prehospital or ED mortality were over three times greater for patients treated in a rural ED (OR 3.44, 95% CI 1.88 to 6.28). Trauma care setting (rural vs urban) was not associated with in-hospital mortality. Nearly all of the specialised services evaluated were more present at urban trauma centres.
Conclusions
Trauma patients treated in rural EDs had a higher mortality rate and were more likely to die prehospital or in the ED compared with patients treated at an urban trauma centre. Our results were limited by a lack of accurate prehospital times in the trauma registry.
