Delaware's inclusive trauma system: impact on mortality

Area of Science:

• Trauma Systems Research
• Public Health Policy
• Injury Prevention and Control

Background:

• Assessing the impact of an inclusive state trauma system on mortality for critically injured patients.
• Evaluating the effectiveness of integrated trauma care networks.

Purpose of the Study:

• To determine if implementing an inclusive state trauma system reduced injury-related mortality.
• To compare mortality trends in Delaware's trauma system with national data.

Main Methods:

• Utilized the state trauma registry (1998-2007) for patients with life-threatening injuries.
• Categorized patients by Injury Severity Score (ISS) and analyzed mortality and transfer rates.
• Compared Delaware's data with the National Trauma Data Bank (NTDB) using statistical analyses (Chi², ANOVA).

Main Results:

• A significant decrease in mortality was observed for the highest Injury Severity Score group (>24), from 45.7% to 20.5%.
• Delaware's mortality reduction rate for this group surpassed national trends shown in the NTDB.
• Interfacility transfers for the most severely injured patients to Level I trauma centers increased significantly.

Conclusions:

• Delaware's inclusive trauma system demonstrably reduced mortality among the most critically injured patients.
• The observed mortality decrease was more substantial than national averages, supporting the benefits of inclusive systems.
• Findings support the adoption and expansion of comprehensive, inclusive trauma care models.
