A postmortem review of trauma mortalities--a comparative study

Area of Science:

• Traumatology
• Public Health
• Emergency Medicine

Background:

• Blunt trauma remains a leading cause of mortality.
• Effective trauma management systems are crucial for improving patient survival.
• Previous studies have indicated variations in outcomes based on trauma care organization.

Purpose of the Study:

• To compare mortality outcomes in blunt trauma patients managed within an organized trauma system versus those treated outside.
• To evaluate the effectiveness of the established trauma management system in Ontario.
• To identify specific factors contributing to differences in patient outcomes.

Main Methods:

• Retrospective review of 202 mortalities from blunt trauma.
• Comparison between cases from the Coroner's Office of Ontario and the Regional Trauma Unit at Sunnybrook Medical Centre (including referring hospitals).
• Exclusion of non-preventable deaths due to head injury; analysis of Injury Severity Score (ISS) and LD50.

Main Results:

• The average postmortem Injury Severity Score (ISS) was higher for patients dying in the Trauma Unit (53) compared to those treated outside (33).
• A significantly lower percentage of patients (5.8%) in the organized trauma system had an ISS below their LD50 compared to the reference group (53%).
• This suggests better management and potentially more severe initial injuries in the organized system.

Conclusions:

• An organized system of trauma management demonstrates clear advantages in patient outcomes.
• Structured trauma care, including timely and appropriate interventions, is associated with improved survival.
• The findings support the continued development and optimization of regional trauma systems.
