Pre-Hospital Mass Casualty Triage and Trauma CareTopic Collection Show July 11, 2019 Performing triage and trauma care during a mass casualty incident (MCI) requires efficiency and coordination among multiple response entities. Efforts may need to be directed toward doing the greatest good for the greatest amount of people, which is counter to day-to-day trauma triage. Simple actions to control bleeding and manage breathing issues can, and do, save lives, and should be part of on-scene care, as appropriate. The majority of emergency management services (EMS) MCI plans are very detailed, and often unlikely to be referenced by responding ambulance personnel. Simple job aids should be provided that can be easily referenced and limited to one page to allow crew members to rapidly review their roles and responsibilities. More detailed plans can be used to support training and policy. Research indicates that the most effective triage is performed by experienced providers using their clinical skill. Tools and protocols such as START or SALT are valuable to personnel that do not routinely triage trauma patients, but trauma criteria applied on an everyday basis to categorize patients as critical should also be applied during mass casualty situations whenever relevant as this generates practice and familiarity. On-scene triage and trauma care should only be conducted if it safe to do so. The safety of first responders and pre-hospital providers is always paramount, and when adequate transportation resources are available triage activities should not delay rapid transport to a trauma hospital. This Topic Collection can help hospital emergency planners, EMS personnel, and emergency medicine clinicians understand the basics of field triage and immediate stabilization of MCI victims. Lessons learned from recent incidents are included. For incident-specific information, access our Topic Collections on Burns, Explosives and Mass Shooting, and Radiological and Nuclear Events.

This chapter in Emergency War Surgery discusses considerations, goals, and protocols for mass casualty triage, from the perspective of the Army.
ASPR TRACIE. (2019). Mass Casualty Trauma Triage: Paradigms and Pitfalls. This ASPR TRACIE white paper can help emergency medical system (EMS) medical directors and EMS systems planners and hospital emergency planners to key differences between “conventional” MCIs and mass violence events when: the scene is dynamic; the number of patients far exceeds usual resources; and usual triage and treatment paradigms may fail.
The authors describe how planning and training for mass-casualty events helped the Boston medical community successfully respond to the marathon bombing. The authors highlight the presence of medical tents, the mobilization of communications and additional resources, and the activation of hospital emergency plans as helpful contributing factors.
The authors analyzed START triage application in several MCIs to determine how efficient, effective and consistently it was performed. In the article they also discuss when it may be appropriate for Emergency Medical Services (EMS) personnel to use other parameters (such as resources available and hospital capabilities) to perform triage and patient distribution in an optimal manner.
This Emergency Medical Service (EMS) bulletin provides direction for the triage and transport of MCI victims. The protocol designates the START/JumpSTART algorithms for primary triage, and instructs EMS providers to use more detailed Trauma Triage Criteria during secondary triage on-scene.
Duckworth, R. (2017). How to Use SALT to Triage MCI Patients. EMS1. The author discusses the implementation of SALT (Sort, Assess, Lifesaving interventions, Treatment and/or Transport) during a mass casualty incident, and the importance of utilizing the triage system to keep patients moving away from the hazard and toward a casualty collection point for further triage.
In 2004, 10 bombs exploded in four commuter trains in Madrid, Spain. The authors provide an in-depth overview of the 250 patients with severe injuries and found the following injuries in patients: soft tissue and musculoskeletal injuries (85%), ear blast injury (67%), blast lung injury (63%), and head trauma (52%).
This resource discusses the call for greater involvement of volunteer responders at the scene of a mass casualty incident to ensure that victims don’t die from uncontrolled bleeding. It reviews the THREAT acronym: Threat suppression. Hemorrhage control. Rapid Extrication to safety. Assessment by medical providers. Transport to definitive care.
This study evaluated the accuracy of SALT (sort–assess–lifesaving interventions–treatment/transport) triage during a simulated mass-casualty incident; the average time it took to make triage designations; and providers' opinions of SALT triage. The authors concluded that the accuracy rate was higher than those published for other triage systems, and of similar speed.
This document contains summaries of critical information for managing the care of children during emergencies or disasters, including vital signs; risks during disasters; signs of respiratory distress; equipment sizes; and fluid resuscitation.
The authors discuss lessons learned from the mass shooting at Fort Hood in 2009. They note that triage was compromised because the scene was not secure for responders, and this led to under triage of several patients. Education and Training
The authors evaluated whether "last-minute" START training of nonmedical ambulance personnel in Italy during a disaster or MCI (using data from a train system victim database as proxy) would result in more effective triage of patients. There was significant improvement in accuracy, and less over- and under-triage for evaluations performed by the group that received just-in-time training on the START protocol. (Note that validation was against the tool itself, making it unclear whether it improved victim triage.)
This seven-and-a-half-minute video demonstrates the Simple Triage and Rapid Treatment (START) Triage system for use during mass casualty incidents.
This presentation includes information on START triage and the SMART patient tagging system. It includes Illinois-approved triage tags and assessment forms, and a link to an online test anyone can take after reviewing the presentation.
This four-day course (usually offered in Anniston, AL) provides emergency medical personnel with hands-on training in the pre-hospital management of Chemical, Biological, Radiological, Nuclear, Explosives and mass casualty incidents, as well as on-scene triage, and field treatment of victims exposed to chemical hazards, biological agents, radiological hazards and explosions. The course concludes with a multi-task, pre-hospital exercise.
Paramedic students (N=22) were trained on SALT and then applied it to triage a bus crash scene; this was repeated 3 months later with SMART. The authors concluded that virtual reality seems to be a viable research tool for examining mass casualty triage, and participants triaged simulated patients faster and with greater accuracy with SMART triage vs. SALT triage.
The authors split 292 paramedics into 4 groups to assess how accurately they applied the triage sieve/algorithm: no training or job aid provided; just-in-time (JIT) training only provided; job aid only provided, and JIT training plus a job aid provided. They found that both JIT training and use of a job aid significantly improved triage accuracy and recommend that paramedics be provided with job aids for field triage because JIT training is impractical when a mass casualty incident occurs. This study also provides some guidance on triage sieve accuracy rate measures.
The authors evaluated the effectiveness of a training model for using mass-casualty incident (MCI) scenarios that trained hospital and prehospital staff together during a one-day training comprised of 2 one-hour functional exercises; 4 distinct, one-hour didactic instructional periods (communications, National Incident Management Systems/Incident Command Systems (NIMS/ICS) and professional roles and responsibilities in NIMS and triage); and 2 MCI functional exercises. Improvements in post-test scores were noted for participants from all disciplines and in all didactic areas. Based on these results, the authors advocate for multidisciplinary MCI training that utilizes real data about a community’s response resources.
This course was designed for emergency responders caring for a large number patients after natural or human-caused incidents. Information on caring for patients exposed to chemical, biological, radiological, nuclear, or explosive (CBRNE) agents is also provided.
The speakers in this webinar discuss the effects of an improvised nuclear detonation on infrastructure, human beings, and medical resources. They then explain field evacuation of three groups (those with combined injuries, radiation exposure, and limited injuries) to four types of healthcare facilities (medical centers, assembly centers, evacuation centers, and centers set up for “national care” purposes). The Radiation Injury Treatment Network is discussed at the end of the webinar.
The authors compared triage skills (decision-making; prioritization of 15 hypothetical casualties involved in a bus crash; and prioritization for evacuation) among Swedish Advanced Trauma Life Support and Pre-Hospital Trauma Life Support course participants before and after their respective trainings. The only improvement in triage skills observed through the post-test was for Pre-Hospital Trauma Life Support participants who had previously participated in real mass casualty incidents (MCIs), or MCI exercises, suggesting the need for changes to these standardized courses.
This series of courses was developed in cooperation with the American College of Surgeons' Committee on Trauma and promote “critical thinking as the foundation for providing quality care.” There are courses for pre-hospital providers, instructors, and first responders.
This webpage provides links to educational opportunities in various categories (e.g., bleeding control, Tactical Combat Casualty Care, and trauma first response) offered by the National Association of Emergency Medical Technicians.
This 15-hour in-person course is geared towards physicians, nurses, physician assistants, emergency medical technicians, and others in similar fields. Simulated all-hazards scenarios are included and allow participants to practice mass casualty triage, and the application of clinical skills for the management of mass casualty victims.
This in-person course can prepare healthcare professionals and first responders for mass casualty events. The basic course is 7.5 hours long and builds upon the Core Disaster Life Support course. It includes information on the use of a standardized step-wise approach and uniform triage categories for mass casualty field triage, as well as the clinical assessment and management of injuries sustained during a disaster.
The National Disaster Life Support Foundation developed this SALT (sort, assess, life-saving interventions, treatment and/or transport) training program for first responders working on a mass casualty incident. This on-line training program consists of a 22 minute video, links to articles on SALT Mass Casualty Triage, and a downloadable PowerPoint set for teaching SALT Triage to others. The program concludes with a short (five question) quiz that participants can take and receive a certificate once complete.
Pauze, D. (2015). Pediatric Triage. University at Albany, State University of New York, School of Public Health and Health Professions, Center for Public Health Preparedness. This archived webcast from a full-day training included identifying the basic steps involved in pediatric disaster triage and describing the fundamental difference between adult and pediatric disaster triage as objectives. Topics covered include: principles of pediatric triage; triage tools & algorithms (START vs. SALT); and PEARLs/pitfalls of pediatric triage.
Teaching methods based on pattern recognition skill development were used to train a group of medical and nursing students to perform triage. A similar group of medical and nursing students was trained using a standardized curriculum. The group taught pattern recognition skills development performed triage more accurately, with a lower overtriage rate than the other group. Emergent Trauma Care
The authors reviewed data from 42,135 records with Abbreviated Injury Scale (AIS) for body regions 4 (Thorax) and 5 (Abdomen) from the National Trauma Database to examine the impact of prehospital time and torso injury severity on survival. They found a “precipitous rise” in patient mortality for patients with non-compressible torso hemorrhage (AIS = 4) and prehospital times >30 min. Rapid transport to trauma centers should be a priority whenever severe torso injury is recognized or suspected.

Data from patients admitted to six Level 1 Trauma Centers in Israel just after a mass casualty incident allowed the authors to develop related guidelines for hospitals to activate in the event of similar events.
In 2004, 10 bombs exploded in four commuter trains in Madrid, Spain. The authors provide an in-depth overview of the 250 patients with severe injuries and found the following injuries in patients: soft tissue and musculoskeletal injuries (85%), ear blast injury (67%), blast lung injury (63%), and head trauma (52%).
The authors conducted a literature search to try to determine the correlation between prehospital time intervals and the outcome of trauma patients. They concluded that patients suffering neurotrauma and hypotensive unstable penetratingly injured patients should be transported to definitive care as quickly as possible. For hemodynamically stable undifferentiated trauma patients, increased on-scene-time and total prehospital time does not increase odds of mortality.
This discussion paper examines some of the issues and potential best practices during responses to terrorist incidents, including mass shootings and bombings. Response coordination and planning considerations are also discussed which could optimize patient outcomes.
The Hartford Consensus suggests that first responders to an active shooter scene should apply the actions in the acronym THREAT: 1) Threat suppression, 2) Hemorrhage control, 3) Rapid Extrication to safety, 4) Assessment by medical providers, and 5) Transport to definitive care.
This resource discusses the call for greater involvement of volunteer responders at the scene of a mass casualty incident to ensure that victims don’t die from uncontrolled bleeding. It reviews the THREAT acronym: Threat suppression. Hemorrhage control. Rapid Extrication to safety. Assessment by medical providers. Transport to definitive care.
The authors explain how post-Katrina “life-and-death triage scenarios” contribute to the need for the “establishment of disaster-specific, consensus-based, public health emergency-related triage protocols-developed with ethical and legal expertise and a renewed focus on multidimensional, multifactorial matrix decision-making processes.”

This book is written for emergency physicians and nurses and Chapter 12 (pp. 174-184) provides a review of triage and covers basic methods. Discussion of the evaluation and treatment of victims suffering from blast injuries, or exposure to chemical, biological, and radiological agents is included in the book with some information about triage in these situations as well.
The authors analyzed data on emergency tourniquet use from a large clinical study to define emergency tourniquet use indications to stop limb bleeding. They concluded that tourniquets should be used on any compressible limb wounds having possibly lethal hemorrhages. They call for additional research to address the gaps in knowledge that exist regarding tourniquet use.
Based on a literature review, the authors discuss some key points for the immediate care of blast injury victims. Specifically, they note that these patients should be treated as having multisystem trauma and managed according to Advanced Trauma Life Support guidelines, and damage control resuscitation should be practiced until definitive hemorrhage control has been achieved.
This plan was prepared to ensure successful coordination between more than one pre-hospital agency and more than one hospital in the state trauma region. Triage and immediate care for victims of a mass casualty incident are discussed.
The authors reviewed data on 50 mass casualties from explosions obtained from the Department of Defense Trauma Registry and the Pre-hospital Trauma Registry. They note that the most common pre-hospital interventions were tourniquet and pressure dressing hemorrhage control, and pain medication administration.

This presentation describes the Rescue Task Force concept, and how the Arlington County, Virginia Fire Department has implemented it to “provide stabilizing medical care in areas that are clear but not secure.”
The authors conducted a literature review of the current protocols of prehospital practice and their impact on outcome in the management of traumatic brain injury (TBI) for the period 1980-2008. The article includes discussion of the management of brain oxygenation, blood pressure, cerebral perfusion pressure, and raised intracranial pressure in the field, as well as considerations for managing TBI during mass casualty incidents.
The author discusses the differences between Tactical Emergency Medical Support (TEMS) and Rescue Task Force (RTF) personnel. RTF providers work with law enforcement to deliver immediate medical intervention (e.g., control severe bleeding; address airway compromise) in the “warm zone” of an active shooter incident to stabilize victims for evacuation to definitive care.
This plan provides prehospital and hospital providers with regional standardized procedures for the treatment of pediatric patients. It addresses various issues to include: prehospital triage, helicopter activation, inter-hospital transfers, pediatric trauma triage/ transfer decision scheme, among others topics.
The authors review advances in prehospital trauma care that improve patient outcomes. They note that training of pre-hospital providers is inconsistent, that the level of care varies, and that standardization of skills that incorporate lessons learned from the most current advances in the field among prehospital providers is warranted to improve patient outcomes.

This plan is an annex to the county’s Multiple Patient Management Plan and describes the setup, management, and utilization of a Field Treatment Site (FTS) during a multiple patient event. The FTS will be used to provide treatment to appropriate (i.e., those not needing immediate transfer to a trauma center) victims after they have been triaged using the START algorithm at a Casualty Collection Point when demand exceeds available transportation resources.
The authors describe the medical response to the attacks from the perspectives of three medical professionals: emergency physician, anesthesiologist, and trauma surgeon.
The authors discuss lessons learned for incident management from a bombing at the central bus station in Tel Aviv in 2006, and describe injury patterns of casualties. They note that quickly responding Emergency Medicine Services (EMS) vehicles, effective primary triage between urgent and non-urgent casualties, and primary distribution between five hospitals contributed to rapid and efficient response.
The authors review mass casualty management in the pre-hospital and hospital settings, and the experience gained from multiple mass casualty incidents experienced in Israel. Lessons Learned

The authors conducted a qualitative evaluation of paramedics’ self-reported obstacles to pediatric disaster triage performance using a 10-victim, multiple-family house fire simulation. Respondents indicated difficulty with triaging multiple child disaster victims “due to emotional obstacles; unfamiliarity with pediatric physiology; and struggles with triage rationale and efficiency.” Mass Triage
This article describes the process of development of the Spanish Prehospital Advanced Triage Method (META), which was designed for use by pre-hospital providers with expert knowledge of Advanced Trauma Life Support (ATLS) during mass casualty incidents. META is based in ATLS protocols, and includes evaluation of each patient’s anatomical injuries and mechanism of injury.

This article reviews existing pre-hospital triage systems to try to correctly categorize burn patients who simultaneously have trauma injuries. The authors contend that additional research is necessary to develop a standardized, evidence-based triage system for these patients.
The authors evaluated whether "last-minute" START training of nonmedical ambulance personnel in Italy during a disaster or MCI (using data from a train system victim database as proxy) would result in more effective triage of patients. There was significant improvement in accuracy, and less over- and under-triage for evaluations performed by the group that received just-in-time training on the START protocol. (Note that validation was against the tool itself, making it unclear whether it improved victim triage.)
The objective of this study was to compare the use of field triage criteria by emergency medical services personnel in six regions. The researchers ultimately found a large variation between the frequency and type of field triage criteria used and suggested opportunities for incorporating updated guidelines.

(Abstract only.) The American Journal of Emergency Medicine. 33(11):1687-91. The authors performed a retrospective chart review of 100 trauma patients seen in their emergency department (ED). They concluded that, overall, neither SALT nor START was sensitive or specific for predicting clinical outcome.
This presentation includes information on START triage and the SMART patient tagging system. It includes Illinois-approved triage tags and assessment forms, and a link to an online test anyone can take after reviewing the presentation.
The authors applied START triage to 228 patients arriving to their stabilization room at a Level 1 trauma center and found 26% of “yellow” patients needed lifesaving interventions within the first few minutes of care and patients categorized “red” by absent radial pulse had 70% mortality. The authors found that START may result in significant under-triage within the yellow category.
The authors analyzed START triage application in several MCIs to determine how efficient, effective and consistently it was performed. In the article they also discuss when it may be appropriate for Emergency Medical Services (EMS) personnel to use other parameters (such as resources available and hospital capabilities) to perform triage and patient distribution in an optimal manner.
This guidance can help emergency medical services providers recognize when patients would benefit from specialized trauma care resources. The report includes a list of tools that can be used to assess vital signs; anatomy of injury; mechanism of injury and evidence of high-energy impact; and special considerations (e.g., age, bleeding disorders, burns, pregnancy).
This review was prepared by the Pacific Northwest Evidence-based Practice Center to assess the predictive utility, reliability, and ease of use of the total Glasgow Coma Scale (tGCS) versus the motor component of the Glasgow Coma Scale (mGCS) for field triage of trauma. The comparative effects on clinical decision-making and outcomes are also discussed.

This guideline describes the purpose and use of a Casualty Collection Point (CCP)/Field Treatment Site (FTS) for managing mass casualty incidents. The CCP/FTS is used for the assembly, triage (sorting), medical stabilization and subsequent evacuation of casualties when demand exceeds transport capacity.
Medical students applied JumpSTART triage to evaluate simulated mass casualty patients (moulaged actors and computer-simulated cases) and the authors assessed overall accuracy and time required for triage, and if the performance of unnecessary steps, or failure to perform required steps, in the algorithm was associated with inaccuracy of triage designation or increased time to reach a triage decision. Increasing triage level, performance of inappropriate actions, and omission of recommended actions were all associated with increasing time to perform triage.
Paramedic students (N=22) were trained on SALT and then applied it to triage a bus crash scene; this was repeated 3 months later with SMART. The authors concluded that virtual reality seems to be a viable research tool for examining mass casualty triage, and participants triaged simulated patients faster and with greater accuracy with SMART triage vs. SALT triage.
Speed and accuracy of a system that can triage injured patients who are or may be contaminated by chemical, biological, radiation, or nuclear (CBRN) material was pilot-tested paramedics at an airport disaster drill on 56 patient scenarios, some involving signs and symptoms of organophosphate toxicity in addition to physical trauma. The study authors concluded that the chemical algorithm of the proposed CBRN-capable mass casualty triage system can be applied rapidly by trained paramedics, but a significant under-triage rate (10.7%) was observed in this pilot test. They call for further refinement and testing of the algorithm.
The authors examined how quickly trained paramedics could triage using the SALT (sort-assess-lifesaving interventions-treat/transport) method. While the method appeared promising, there was overtriage, and the authors indicated the need for more research.
The authors applied the Sacco Triage Method to 90,037 records of children = 18 years of age with complete initial scene data from the National Trauma Database for the period 2007-2009. They concluded that this method is a highly accurate predictor of mortality in pediatric trauma patients in this registry database.
The authors used data from 322,162 subjects in the National Trauma Database (NTDB) to assess gaps of the START algorithm when it is used to triage low-acuity patients. They identified factors for mistriage of “Green/Minor” level patients who died in the hospital (N=2,046), and then developed and tested evidenced-based improvements to START using an iterative process. They concluded that START accuracy was significantly improved when elderly, but otherwise minimally injured patients were triaged as “Yellow” instead of “Green.”
The authors split 292 paramedics into 4 groups to assess how accurately they applied the triage sieve/algorithm: no training or job aid provided; just-in-time (JIT) training only provided; job aid only provided, and JIT training plus a job aid provided. They found that both JIT training and use of a job aid significantly improved triage accuracy and recommend that paramedics be provided with job aids for field triage because JIT training is impractical when a mass casualty incident occurs. This study also provides some guidance on triage sieve accuracy rate measures.
The authors discuss the importance of collaboration among disciplines for conducting triage, from field/on-scene triage, through to the Emergency Department, and beyond. Triage algorithms and considerations are presented.
Duckworth, R. (2017). How to Use SALT to Triage MCI Patients. EMS1. The author discusses the implementation of SALT (Sort, Assess, Lifesaving interventions, Treatment and/or Transport) during a mass casualty incident, and the importance of utilizing the triage system to keep patients moving away from the hazard and toward a casualty collection point for further triage.
The author discusses the foundations of triage, lists challenges associated with triaging after a mass casualty incident, shared data on under- and over-triage, and lists factors that should be taken into account when making triage decisions.
In 2004, 10 bombs exploded in four commuter trains in Madrid, Spain. The authors provide an in-depth overview of the 250 patients with severe injuries and found the following injuries in patients: soft tissue and musculoskeletal injuries (85%), ear blast injury (67%), blast lung injury (63%), and head trauma (52%).
This is a commentary on a study that examined the use of JumpSTART triage by medical students, wherein they either performed unnecessary steps (55.0% of the time) or omitted them (57.0%), even with notes to help them follow the algorithm. The authors contend that, regardless of how the information is taught to the medical community, the algorithm does not work, and so should not be accepted in the first place. They cite other studies that have demonstrated that “application of JumpSTART is more likely to triage patients incorrectly than any other decision-making tool, including a coin toss.” They call for more research to create new triage paradigms.
The authors used a streamlined version of Focused Assessment with Sonography for Trauma (sFAST) to perform field triage of injured patients for the first 24 hours after a large earthquake. They compared their results to those obtained using the START algorithm, and determined that ultrasound yielded significantly more predictive information in a similar period of time.
This article provides information on the history and evolution of the practice of triage. It includes a chart detailing the “continuum of triage” from “most resources, most social order, to fewest resources, chaos.” (Part II by Moskop and Iserson is also annotated in this collection.)
Paramedics received a 15-minute training in either JumpSTART or SALT and then were asked to assign triage categories to 10 pediatric patients in a simulated building collapse (4 moulaged actors; 6 high-fidelity simulators) using whichever method they were trained in. Study authors concluded that SALT is at least as good as JumpSTART in overall triage accuracy (~66% for each), overtriage (~23% for each), or undertriage (~11% for each) rates in a simulated pediatric mass casualty incident. Both were considered easy to use, and JumpSTART was 8 seconds faster per patient to assign triage designations.
The authors reviewed 148 patient records from 14 hospitals after a train crash to determine how well triage levels assigned in the field using START corresponded with outcomes-based triage levels assigned at the hospital. Seventy-nine patients were overtriaged; 3 were undertriaged; and 66 patients' outcomes matched their triage level.
The authors reviewed 11 papers as part of a literature review conducted to identify existing triage tools and to determine the extent to which their reliability and validity have been assessed. They concluded that there is limited evidence for the validity of existing triage tools in ‘big bang’ major incidents, and what evidence there is focuses on sensitivity and specificity in relation to prediction of trauma death or severity of injury based on data from single or small number patient incidents.
The authors conducted a retrospective analysis of a statewide trauma registry including records from 393,877 patients from 1999 to 2013 to compare the predictive ability of a total Glasgow Coma Scale (GCS) =13 vs. a Glasgow Coma Scale motor component (GCS-m) <6>
Participants in the Advanced Trauma Life Support (ATLS) provider course (N=142) completed pre- and post-tests to determine whether the mnemonic ABCDE as instructed in the ATLS provider course, affects the ability of Swedish physicians to correctly triage patients in a simulated mass casualty incident. Post-test results did not show improvement in the ability of physicians to perform triage using the ABCDE algorithm.
First-year primary care paramedic (PCP), fire, and police trainees attended a 30-minute didactic training on SALT and completed a paper-based test to assess their ability to understand and apply SALT immediately thereafter, and again 3 months later. PCPs were able to apply the SALT triage tool with the most accuracy, followed by fire, then police. Over-triage was the most frequent error, and critical errors were rare.
The authors compared triage accuracy, error patterns, and time to triage completion using SALT during a mock mass casualty incident using 8 moulaged actors following a 30-minute didactic training of second year fire service and paramedic students. They found that accuracy was slightly higher among paramedic students (79.9% vs. 72.0% for fire students), and suggest that fire service personnel may be used to support triage during MCIs when medical resources are limited.
The authors conducted a structured medical record review of children =15 years old that were transported to trauma centers in 3 midsize cities to determine the accuracy of the Physiologic Criteria (Step 1) of the Field Triage Guidelines in identifying injured children who need the resources of a trauma center. They concluded that the Physiologic Criteria are a moderate predictor of trauma center need, and their predictive value may have been limited by inaccurate or missing vital signs.
The authors discuss the development of the SALT (sort, assess, life-saving interventions, treatment and/or transport) triage guidelines, based on the best available science and consensus opinion. SALT was developed as “a single overarching guide for unifying the mass casualty triage process across the United States.”
This study evaluated the accuracy of SALT (sort–assess–lifesaving interventions–treatment/transport) triage during a simulated mass-casualty incident; the average time it took to make triage designations; and providers' opinions of SALT triage. The authors concluded that the accuracy rate was higher than those published for other triage systems, and of similar speed.
The authors conducted an extensive literature review to answer the questions: 1) are pre-hospital triage systems effective, 2) is one triage system more effective than others, and 3) is it effective to use the same triage system in two or more settings of the EMS-chain? They found a gap in the literature and were unable to draw any conclusions.
The authors created a “fluid model” of patient triage in a mass-casualty incident that incorporates resource limitations and the changes in survival probabilities with respect to time. They tested it using a simulation model and data from emergency medicine literature, and conclude that the policy developed outperforms START in all scenarios considered.
In this article on the foundations of triage decision making, the authors discuss the "moral significance" of triage and summarize three principles of distributive justice that can guide triage decisions. (Part I by Iserson and Moskop is also annotated in this collection.)
Powers, R., Daily, E., and The World Association of Disaster and Emergency Medicine. (2010). International Disaster Nursing. (Book available for purchase.) Cambridge University Press. This book covers “the essential components of practice” during disasters, including disaster triage. Organizational aspects of preparedness and response, as well as individual and team roles and responsibilities, are discussed.
The authors conducted a retrospective observational cohort study using data from 31,292 patients in the UK Trauma Audit and Research Network (TARN) database aged less than 16 years who sustained a traumatic injury. They assessed sensitivity, specificity and level of agreement between five triage tools (JumpSTART, START, CareFlight, Paediatric Triage Tape/Sieve and Triage Sort) to identify patients at high risk of death or severe injury. They concluded that “no single tool performed consistently well across all evaluated scenarios.”
The authors studied ambulance personnel attitude towards, and experiences of, practicing triage tagging during day-to-day management of trauma patients, as well as in major incidents (MIs), using questionnaires and focus groups. They found that, although ambulance personnel accept the value of using triage tags, they will likely not use them during MIs because they don’t have much experience with them during day-to-day operations or through exercises.
The authors retrospectively analyzed data from 383 records obtained from local trauma registries and hospital and ambulance records in Stockholm County, Sweden. They found that males were more likely to be transported directly to a trauma center than females, and hypothesize that this may be due to gender differences in symptom presentation that physiologic criteria for triage do not account for. There were no differences in total on-scene time or on-scene interventions provided between genders.

Ten paramedics with field experience were trained in the use of Focused Abdominal Sonography in Trauma (FAST) scan, which is used to detect free fluid in the peritoneal cavity, or pericardium, to identify injuries needing immediate surgical intervention. After 2 weeks, they used FAST to attempt to correctly identify patients with such fluid conditions. Mean accuracy was found to be low (60%; range 40-80%), and false positives (59%) were significantly greater than false negatives detected (41%).
The authors discuss lessons learned from the mass shooting at Fort Hood in 2009. They note that triage was compromised because the scene was not secure for responders, and this led to under triage of several patients.
The authors present their literature review regarding the application of sonography in mass casualty incidents (MCI) and disaster scenarios, focusing on the most promising and practical ultrasound-based paradigms applicable in these settings. Plans, Tools, and Templates
This guidance can help emergency medical services providers recognize when patients would benefit from specialized trauma care resources. The report includes a list of tools that can be used to assess vital signs; anatomy of injury; mechanism of injury and evidence of high-energy impact; and special considerations (e.g., age, bleeding disorders, burns, pregnancy).
This resource provides guidelines for the immediate on-scene stabilization of victims, depending on whether or not there is an ongoing threat to safety.
This Emergency Medical Service (EMS) bulletin provides direction for the triage and transport of MCI victims. The protocol designates the START/JumpSTART algorithms for primary triage, and instructs EMS providers to use more detailed Trauma Triage Criteria during secondary triage on-scene.
This plan is an annex to the county’s Multiple Patient Management Plan and describes the setup, management, and utilization of a Field Treatment Site (FTS) during a multiple patient event. The FTS will be used to provide treatment to appropriate (i.e., those not needing immediate transfer to a trauma center) victims after they have been triaged using the START algorithm at a Casualty Collection Point when demand exceeds available transportation resources.
This document contains summaries of critical information for managing the care of children during emergencies or disasters, including vital signs; risks during disasters; signs of respiratory distress; equipment sizes; and fluid resuscitation.
Metropolitan EMS Board – Minnesota. (2012). Incident Response Plan. This brief job action sheet has been adopted by the 24 agencies in the Minneapolis / St. Paul area for rapid reference by arriving ambulances to a mass casualty incident scene. It emphasizes initial tasks, staging, and rapid transport.
This plan was prepared to ensure successful coordination between more than one pre-hospital agency and more than one hospital in the state trauma region. Triage and immediate care for victims of a mass casualty incident are discussed.
This plan provides prehospital and hospital providers with regional standardized procedures for the treatment of pediatric patients. It addresses various issues to include: prehospital triage, helicopter activation, inter-hospital transfers, pediatric trauma triage/ transfer decision scheme, among others topics. Agencies and Organizations
This webpage provides information and links to resources related to the “Stop the Bleed” initiative. This initiative seeks to prepare trauma professionals, professional first responders, and immediate responders (i.e., citizens) who can respond and stop bleeding of victims of mass casualty incidents.
