In 2006, the National Association of EMS Physicians (NAEMSP), with funding from the Centers for Disease Control and Prevention (CDC), convened a workgroup (hereafter the SALT workgroup) of subject matter experts from national stakeholder organizations, to examine the science supporting existing mass casualty triage systems and make a recommendation for the adoption of a single system as a national standard . In an article published in Disaster Medicine and Public Health Preparedness the SALT workgroup stated that “[t]he committee conducted their work through a series of conference calls and two face-to-face meetings . Initially, a list of all mass casualty triage systems was generated and reviewed by all of the members [of the SALT workgroup] to ensure it was complete . Each member was assigned a triage system and asked to conduct an exhaustive literature review and develop a report of the system for the group . This review included peer-reviewed publications as well as other types of reports . Each system had two or more members assigned to conduct a review . The reviews were presented to the group and a grid was developed that described each system in regards to several parameters (e .g ., color codes, training time and costs, when a patient is designated as dead) .”
