RESUMEN
OBJECTIVE: The number of mass casualty incidents (MCIs) has been steadily increasing. High-priority MCI patient outcomes are highly dependent on rapid identification, treatment, and transport. Although there are several methods used to mark patients for rapid extraction, most current methods utilize low-profile tags, with no gold standard. This study examines if the use of a vertical cue, a triage flag, to identify high priority MCI patients results in faster extraction times than those with a wrist triage tag alone. METHODS: A prospective randomized crossover study was conducted with medical students trained in basic disaster life support, who completed 2 extraction simulations. Two fields were each arranged with 32 randomly placed, pretriaged manikins (10 red, 17 yellow, 5 black). The manikins were marked with either triage tags alone or with triage tags and flags. The total time elapsed for participants to report all high-priority manikin triage tag numbers was recorded. RESULTS: Eighty-two participants completed both simulations. The average completion time for the "tags-only" simulation was 94.5 seconds (±16.4 seconds) compared to 70.7 seconds (±13.2 seconds) for the flags and tags simulation. This corresponds to an average decrease of 23.8 seconds (P < 0.0001), or a 25.2% reduction in time. CONCLUSION: Using a vertical cue decreased the time required to identify high-priority patients. This suggests that a rapidly deployable and visually apparent triage marker may allow faster identification and extraction of patients across a field of victims with varying injury severities than a flat horizontal triage tag, thereby potentially improving patient outcomes.
