Method and system of mass and multiple casualty triage
InactiveUS7761309B2Maximize survivabilityMaximize savingMental therapiesDiagnostic recording/measuringTriageDeterioration rate
The present invention is a method and system of triage that assesses a severity score for each casualty, and determines a treatment prioritization plan to maximize the number of survivors. The present invention includes a score-based mathematical algorithm for resource-constrained triage, where an optimal number of survivors is determined through a methodology that can be mathematically modeled and solved, a methodology that considers victim survival probabilities, victim deterioration rates, and resource availability. First, each casualty is assessed and an RPM severity score is assigned based upon a sum of coded values for respiratory rate, pulse rate, and best motor response. Next, treatment priorities are determined from analytical or mathematical techniques, such as dynamic or linear programming, in consideration of survival probabilities associated with each RPM score, and deterioration-with-time rates for each RPM score for victims awaiting transport and treatment and the availability and timing of transport and treatment services.

Method and system of rule-based triage
InactiveUS7899682B2Maximize survivabilityMaximize savingFinanceEpidemiological alert systemsTriageData dredging
A method and system for ordering treatment or transport of victims of a mass casualty incident, prior to the incident, by establishing simulated casualty severity scores for each of the victims and considering the casualty severity scores and simulated resource availability. The order of treatment is provided on a card, chart, table or graph. Ordering treatment occurs through an analysis of triage simulations using analytical or mathematical programming techniques considering the severity scores, time periods of treatment delay resulting from constrained resources, estimated survival probabilities, and / or deterioration rates applied to the severity scores due to treatment delay. Alternatively, the order of treatment can be determined through data mining, pattern recognition, or greedy algorithm optimization techniques analyzing survival probability estimates associated with the simulated casualty severity scores, and changes to the survival probability estimates due to time periods of treatment delay resulting from constrained resources.
