Medical professionals can use mass-casualty triage systems to assist them in prioritizing patients from mass-casualty incidents (MCIs). Correct triaging of victims will increase their chances of survival. Determining the triage system that has the best performance has proven to be a difficult question to answer. The Advanced Prehospital Triage Model (Modelo Extrahospitalario de Triaje Avanzado; META) and Sort, Assess, Lifesaving Interventions, Treatment/Transport (SALT) algorithms are the most recent triage techniques to be published. The present study aimed to evaluate the META and SALT algorithms’ performance and statistical agreement with various standards. The secondary objective was to determine whether these two MCI triage systems predicted patient outcomes, such as mortality, length-of-stay, and intensive care unit (ICU) admission.

This retrospective study used patient data from the trauma registry of an American College of Surgeons Level 1 trauma center, from January 1, 2018 through December 31, 2020. The sensitivity, specificity, and statistical agreement of the META and SALT triage systems to various standards (Revised Trauma Score [RTS]/Sort Triage, Injury Severity Score [ISS], and Lerner criteria) when applied using trauma patients. Statistical analysis was used to assess the relationship between each triage category and the secondary outcomes.

A total of 3,097 cases were included in the study. Using Sort triage as the standard, SALT and META showed much higher sensitivity and specificity in the Immediate category than for Delayed (Immediate sensitivity META 91.5%, SALT 94.9%; specificity 60.8%, 72.7% versus Delayed sensitivity 28.9%, 1.3%; specificity 42.4%, 28.9%). With the Lerner criteria, in the Immediate category, META had higher sensitivity (77.1%, SALT 68.6%) but lower specificity (61.1%) than SALT (71.8%). For the Delayed category, SALT showed higher sensitivity (META 61.4%, SALT 72.2%), but lower specificity (META 75.1%, SALT 67.2%). Both systems showed a positive, though modest, correlation with ISS. For SALT and META, triaged Immediate patients tended to have higher mortality and longer ICU and hospital lengths-of-stay.

Both META and SALT triage appear to be more accurate with Immediate category patients, as opposed to Delayed category patients. With both systems, patients triaged as Immediate have higher mortality and longer lengths-of-stay when compared to Delayed patients. Further research can help refine MCI triage systems and improve accuracy.

This paper aims to clarify how the Project for Strengthening the ASEAN Regional Capacity on Disaster Health Management (ARCH Project) strengthened regional collaboration mechanisms on disaster health management (DHM) in ASEAN.

The political process and the relevant documents of the ARCH Project were reviewed.

The ARCH Project established the Regional Coordination Committee as a coordination platform for providing strategic direction to the project and strengthening the regional coordination of DHM. Also, the Project Working Groups and Sub-Working Groups were set up as implementation bodies for the project activities with representatives of ASEAN Member States (AMS). With support from DHM experts of Japan and Thailand, a series of discussions were conducted for the development of a Standard Operating Procedure (SOP) for the Coordination of International Emergency Medical Teams (I-EMTs), regional tools, and collective measures supporting AMS to overcome challenges, and thereby meeting the minimum requirements set by the WHO EMT Initiative. The progress and outputs of the ARCH Project are subsequently elevated to the ASEAN Health Sector for endorsement, the updates are further shared to the Joint Task Force to Promote Synergy with Other Relevant ASEAN Bodies on Humanitarian Assistance and Disaster Relief (JTF-HADR) for the implementation of the ASEAN Declaration on One ASEAN One Response. The initiation of the ARCH Project in July 2016 has resulted in the development of the ASEAN regional collaboration framework, including the establishment of the Regional Coordination Committee on Disaster Health Management (RCCDHM), the SOP for ASEAN I-EMT coordination, and regional tools, such as forms for Medical Record for Emergency and Disaster and Health Needs Assessment. Moreover, further discussions on ASEAN Collective Measures that aim to support AMS to meet the WHO EMT minimum standards and strengthening I-EMT coordination capacity were also conducted. As adopted by the ASEAN Health Ministers Meeting (AHMM) in 2019, the RCCDHM was established as one of the mechanisms to operationalize the Plan of Action to implement the ASEAN Leaders’ Declaration on DHM.

The contribution of the ARCH Project to strengthen the ASEAN regional capacity in DHM has enhanced the regional coordination platform, with a formalization of RCCDHM as ASEAN’s official regional mechanism, and of the on-going integration process of the SOP for EMT coordination into the ASEAN SASOP.
