These criteria (Tables 1-4) reflect the available science, but it is acknowledged that there are significant research gaps. When no sci- ence was available, decisions were formed by expert consensus derived from the available triage systems. The intent is to ensure that providers at a mass-casualty incident use triage methodologies that incorporate these core principles in an effort to promote interoperability and standardization. At a minimum, each triage system must incorporate the criteriathatarelistedbelow.Masscasualtytriagesystemsinusecanbemodifiedusingthesecriteriatoensureinteroperability. The criteria include general considerations, global sorting, lifesaving interventions, and assignment of triage cat- egories. The criteria apply only to providers who are organizing multiple victims in a discrete geographic location or locations, regardless of the size of the incident. They are classified by whether they were derived through avail- able direct scientific evidence, indirect scientific evidence, expert consensus, and/or are used in multiple existing triage systems. These criteria address only primary triage and do not consider secondary triage. For the pur- poses of this document the term triage refers to mass-casualty triage and provider refers to any person who assigns primary triage categories to victims of a mass-casualty incident.

Wallis and Carley 20061,2 1.2 Triage systems must be applicable across the broad Consensus Hodgetts 2001; Baker 2004; range of mass casualty incidents where there is a Cone and Koenig 20053-5 single location with multiple patients. 1.3 Triage systems must be simple, easy to remember, Indirect Science Other Systems Kilner and Hall 2005; and amenable to quick memory aids. Wang and Hung 20052,6 1.4 Triage systems must be rapid to apply and practical Consensus Other Systems Lee, Chiu et al. 20027 for use in an austere environment. 1.5 Triage systems are resource dependent and the system Consensus Other Systems Benson, Koenig et al. 19968 must allow for dynamic triage decisions based on changes in available resources and patient conditions. 1.6 The triage system must require that the assigned Consensus triage category for each patient be visibly identifiable (eg, triage tags, tarps, markers). 1.7 Triage is dynamic and reflects patient condition and Consensus Okumura, Suzuki et al. 1998; available resources at the time of assessment.

Garner, Lee et al. 2001; Holcomb, Niles et al. 200514-16 2.2 First priority for individual assessment is to Indirect Science Meredith, Rutledge et al. 1995; identify those who are likely to need a Garner, Lee et al. 2001; Lifesaving Intervention. They can be identified Holcomb, Niles et al. 2005; as those: (1) unable to follow commands and Kragh, Walters et al. 2008; not making purposeful movements, or (2) Kragh, Littrel et al. 2009; those with an obvious life threat (eg, life Kragh, Walters et al. 200910-12,14-16 threatening external hemorrhage). 2.3 Second priority for individual assessment will Indirect Science Meredith, Rutledge et al. 1995; be those who are unable to follow the Garner, Lee et al. 2001; command to ambulate to an assigned place Holcomb, Niles et al. 200514-16 but are able to follow other commands (eg, wave) or make purposeful movement. 2.4 Last priority for individual assessment will be Indirect Science Other Systems Meredith, Rutledge et al. 1995; those who follow commands by ambulating to Garner, Lee et al. 2001; an assigned place (or making purposeful Holcomb, Niles et al. 200514-16 movements) and have no obvious life threatening conditions (eg, life threatening external hemorrhage). 2.5 All patients must be individually assessed Indirect Science Garner, Lee et al. 2001; regardless of their initial prioritization during de Ceballos, Turegano-Fuentes global sorting.
