Summary
Canadian trauma systems show variations in how trauma centers (TCs) distribute patients and impact outcomes. Standardized data collection is needed to improve national trauma care quality.
Area of Science:
- Trauma care systems
- Health services research
- Injury epidemiology
Background:
- North American trauma systems utilize designated trauma centers (TCs) with varying levels (I, II, III).
- Provincial trauma system configurations differ, impacting patient distribution and outcomes.
- The functional roles of TCs across different levels and provinces require investigation.
Purpose of the Study:
- To compare patient case mix, case volumes, and risk-adjusted outcomes for major trauma patients across designated level I, II, and III TCs in Canadian trauma systems.
- To identify variations in patient distribution and clinical outcomes influenced by TC designation and provincial system structures.
Main Methods:
- National historical cohort study utilizing data from Canadian provincial trauma registries (2013-2018).
- Inclusion of major trauma patients treated in designated level I, II, and III TCs across British Columbia, Alberta, Quebec, Nova Scotia, New Brunswick, and Ontario.
- Multilevel generalized linear models and competitive risk models were used to analyze mortality, intensive care unit (ICU) admission, and length of stay (LOS).
Main Results:
- The study included 50,959 major trauma patients.
- Patient distributions in level I and II TCs were consistent across provinces, but level III TCs showed significant differences in case mix and volumes.
- Low variation in risk-adjusted mortality and LOS was observed, contrasted by high interprovincial and intercenter variation in risk-adjusted ICU admission.
Conclusions:
- Differences in TC designation levels and provincial system structures significantly affect patient distribution, case volumes, resource utilization, and clinical outcomes.
- Findings highlight opportunities for improving Canadian trauma care through better standardization.
- The need for standardized, population-based injury data is emphasized for national quality improvement initiatives.
