Mass casualty triage is the process of prioritizing multiple victims when resources are not sufficient to treat everyone immediately. No national guideline for mass casualty triage exists in the United States. The lack of a national guideline has resulted in variability in triage processes, tags, and nomenclature. This variability has the potential to inject confusion and miscommunication into the disaster incident, particularly when multiple jurisdictions are involved. The Model Uniform Core Criteria for Mass Casualty Triage were developed to be a national guideline for mass casualty triage to ensure interoperability and standardization when responding to a mass casualty incident. The Core Criteria consist of 4 categories: general considerations, global sorting, lifesaving interventions, and individual assessment of triage category. The criteria within each of these categories were developed by a workgroup of experts representing national stakeholder organizations who used the best available science and, when necessary, consensus opinion. This article describes how the Model Uniform Core Criteria for Mass Casualty Triage were developed.

A simulation-based training system for surgical wound debridement was developed and comprises a multimedia introduction, a surgical simulator (tutorial component), and an assessment component. The simulator includes two PCs, a haptic device, and mirrored display. Debridement is performed on a virtual leg model with a shallow laceration wound superimposed. Trainees are instructed to remove debris with forceps, scrub with a brush, and rinse with saline solution to maintain sterility. Research and development issues currently under investigation include tissue deformation models using mass-spring system and finite element methods; tissue cutting using a high-resolution volumetric mesh and dynamic topology; and accurate collision detection, cutting, and soft-body haptic rendering for two devices within the same haptic space.

Background: We hypothesized that clinical factors accurately identify those trauma patients at high risk for pelvic fractures making routine films unnecessary., Methods: Blunt trauma patients were prospectively analyzed both with and without a clinical protocol. The protocol group had pelvic films obtained only if they had a Glasgow Coma Scale score < 13 or had signs and symptoms of pelvic or back injury., Results: The protocol patients with fractures (n = 45) had a higher Injury Severity Score (p = 0.001) and lower systolic blood pressure (p = 0.04) than those without fractures (n = 475). All 45 patients with pelvic fractures were identified by history and physical examination (p = 0.001). The clinical assessment resulted in a sensitivity and a negative predictive value of 100%. A total of 273 films were eliminated, resulting in a charge savings of $51,051. A comparison between the protocol and nonprotocol groups showed the nonprotocol patients with pelvic fractures to have a higher Injury Severity Score (p < 0.002). All of these patients' pelvic fractures were identified by clinical evaluation (67 of 67)., Conclusion: In the awake and alert patient, the need for a pelvic radiograph was readily identified by clinical examination. Because elimination of this film would result in financial savings, its routine use should be removed from standard trauma protocols in the minimally injured patient and limited to severely injured patients as recommended by the Advanced Trauma Life Support protocol.
