Trauma system regionalization improves mortality in patients requiring trauma laparotomy

Area of Science:

• Trauma Surgery
• Healthcare Systems
• Public Health

Background:

• Trauma laparotomy patients represent a critically injured population.
• Evaluating the impact of organized trauma systems on patient outcomes is crucial.
• Regionalization of trauma care aims to improve access to specialized centers.

Purpose of the Study:

• To assess the effect of a regional trauma network (RTN) on mortality and resource utilization in patients undergoing trauma laparotomy.
• To compare outcomes between patients treated before and after the implementation of an RTN.

Main Methods:

• Retrospective analysis of 569 patients who required trauma laparotomy between January 2008 and December 2013.
• Patients were categorized into pre-RTN (2008-2009) and RTN (2011-2013) groups.
• Primary outcome was in-hospital mortality; secondary outcomes included intensive care unit (ICU) and hospital length of stay.

Main Results:

• The RTN group (338 patients) showed a 35% relative reduction in mortality compared to the pre-RTN group (231 patients) (p=0.035).
• RTN implementation resulted in 30% more patients being triaged to Level 1 trauma centers (p<0.001).
• Significant mortality reduction was observed in blunt trauma patients (38% to 23%, p=0.017) and a 1-day reduction in ICU stay for penetrating trauma patients (p=0.001).

Conclusions:

• Regionalization of trauma care through an RTN significantly improves survival rates for patients requiring trauma laparotomy.
• RTN enhances patient triage to higher-level trauma centers and reduces ICU length of stay.
• The study demonstrates the benefits of a structured trauma system in managing critically injured patients.
