Evolution and organisation of trauma systems.

Area of Science:

• Emergency Medicine
• Trauma Surgery
• Public Health Systems

Background:

• Severe trauma patient prognosis has improved over 20 years with trauma network establishment.
• Trauma networks can be exclusive (designated centers) or inclusive (capacity-based referral).
• Hospital classification (Levels 1-3) correlates with technical facilities and patient volume, impacting outcomes for severely injured patients.

Purpose of the Study:

• To highlight the importance of trauma networks in improving severe trauma patient prognosis.
• To discuss the principles of effective patient triage within trauma systems.
• To emphasize the need for evaluating trauma networks and establishing patient registries.

Main Methods:

• Review of studies on trauma network effectiveness over the past 20 years.
• Analysis of patient triage methods including clinical criteria, vital signs, and scoring systems (e.g., RTS, MGAP).
• Discussion of exclusive versus inclusive trauma network models and hospital classification.

Main Results:

• Trauma networks consistently show improved patient prognosis.
• Optimal outcomes for severely injured patients (hemorrhagic shock, head trauma) are linked to high-volume, high-facility hospitals.
• Effective triage avoids under-triage (re-transfer, time loss) and over-triage (resource misuse, cost increase).

Conclusions:

• Trauma networks are essential for reducing mortality and morbidity in severe injury patients.
• Careful prehospital evaluation and triage are critical for directing patients to appropriate care centers.
• Ongoing evaluation and data collection through registries are necessary for trauma network optimization.
