Data collection in a live mass casualty incident simulation: automated RFID technology versus manually recorded system.

OBJECTIVES: To demonstrate the applicability and the reliability of a radio frequency identification (RFID) system to collect data during a live exercise. METHODS: A rooftop collapse of a crowded building was simulated. Fifty-three volunteers were trained to perform as smart victims, simulating clinical conditions, using dynamic data cards, and capturing delay times and triage codes. Every victim was also equipped with a RFID tag. RFID antenna was placed at the entrance of the advanced medical post (AMP) and emergency department (ED) and recorded casualties entering the hospital. RESULTS: A total of 12 victims entered AMP and 31 victims were directly transferred to the ED. 100% (12 of 12 and 31 of 31) of the time cards reported a manually written hospital admission time. No failures occurred in tag reading or data transfers. A correlation analysis was performed between the two methods plotting the paired RFID and manual times and resulted in a r=0.977 for the AMP and r=0.986 for the ED with a P value of less than 0.001. CONCLUSION: We confirmed the applicability of RFID system to the collection of time delays. Its use should be investigated in every aspect of data collection (triage, treatments) during a disaster exercise.

Evaluation of medical management during a mass casualty incident exercise: an objective assessment tool to enhance direct observation.

BACKGROUND: Functional exercises represent an important link between disaster planning and disaster response. Although these exercises are widely performed, no standardized method exists for their evaluation. STUDY OBJECTIVES: To describe a simple and objective method to assess medical performance during functional exercise events. METHODS: An evaluation tool comprising three data fields (triage, clinical maneuvers, and radio usage), accompanied by direct anecdotal observational methods, was used to evaluate a large functional mass casualty incident exercise. RESULTS: Seventeen medical responders managed 112 victims of a simulated building explosion. Although 81% of the patients were assigned the appropriate triage codes, evacuation from the site did not follow in priority. Required maneuvers were performed correctly in 85.2% of airway maneuvers and 78.7% of breathing maneuvers, however, significant under-treatment occurred, possibly due to equipment shortages. Extensive use of radio communication was documented. In evaluating this tool, the structured markers were informative, but further information provided by direct observation was invaluable. CONCLUSION: A three-part tool (triage, medical maneuvers, and radio usage) can provide a method to evaluate functional mass casualty incident exercises, and is easily implemented. For the best results, it should be used in conjunction with direct observation. The evaluation tool has great potential as a reproducible and internationally recognized tool for evaluating disaster management exercises.
