Mass Casualty Event During a Musical Parade: Lessons Learned

Area of Science:

• Emergency Medicine
• Disaster Management
• Trauma Care

Background:

• Major incidents are infrequent in the Netherlands, leading to a perception of low risk.
• A review of 39 major casualty events over 60 years highlights the need for preparedness.
• This study focuses on a specific urban mass casualty incident (MCI) to evaluate response effectiveness.

Purpose of the Study:

• To critically evaluate the response and outcomes of an urban mass casualty incident.
• To identify lessons learned from a real-world MCI for future disaster training and planning.
• To assess the effectiveness of triage and trauma team performance during a mass casualty event.

Main Methods:

• Retrospective analysis of patient records from an August 2006 mass casualty incident.
• Data collection focused on all aspects of patient care from scene to treatment.
• Involved 19 patients with 21 casualties at the scene, requiring extensive diagnostic imaging.

Main Results:

• 19 patients were treated, with 12 in the crash room and 4 hospital admissions.
• Extensive diagnostic imaging included 87 X-rays, 1 ultrasound, and 15 CT scans.
• Psychological support was provided to all patients; one patient died three days post-incident.

Conclusions:

• Triage systems and trauma teams performed adequately, with undertriage/overtriage rates consistent with literature.
• Patient numbering facilitated care but created logistical challenges for support services.
• Centralized trauma care offered benefits, but surge capacity (20 patients) must be respected, necessitating alternative plans for larger events.
