First EMS Unit on SceneeScene.01Documentation that this EMS unit was the first EMS unit for theEMS agency on the scene.45. Number of Patients at SceneeScene.06Indicator of how many total patients were at the scene.46. Mass Casualty Incident (MCI)eScene.07Indicator if this event would be considered a mass casualtyincident (overwhelmed existing EMS resources).47. Triage Classification for MCIPatienteScene.08The color associated with the initial triageassessment/classification of the MCI patient.5Can inform epidemiological investigationsthrough stratification of data.Can inform epidemiological investigationsthrough stratification of data.Helps to track individual patient outcomes.Describes the payment breakdown amongEMS patients to better understand thepopulation served.The beneficiary's condition must require theambulance transportation itself and thelevel of service provided for the billedservice to be considered medicallynecessary.Added to improve the evaluation ofresponse times when multiple EMS unitsare responding to the same scene.The number of patients requiring care canshed light on the load/burden on an EMScrew.Surveillance of mass casualty incidents andstresses to the medical system are key totrack.Adapted from SALT mass casualty triage:concept endorsed by the American Collegeof Emergency Physicians, American Collegeof Surgeons Committee on Trauma,American Trauma Society, NationalAssociation of EMS Physicians, NationalDisaster Life Support Education Consortium,and State and Territorial Injury PreventionDirectors Association.
