Prehospital Mass-Casualty Triage Training—Written Versus Moulage Scenarios: How Much Do EMS Providers Retain?

Triaging in Mass Casualty Incidents: A Simulation-Based Scenario Training for Emergency Care Senior Residents

BACKGROUND

Mass casualty incidents (MCIs) are events where the number of patients may exceed the resources available for emergency management. In emergency departments (ED), MCIs go along with high patient allocation in a short time period. For ED staff, simulation-based immersive scenario training can be an effective tool to develop communicative and leadership competencies to manage these situations.

APPROACH

A novel simulation-based immersion experience was developed for senior residents in emergency care. To our knowledge, this is the first scenario training focusing on in-hospital triage and management of MCI in an ED using simulated patients, visual tracking, bodycams and active participant location tracking as educational tools. The participants were either directly involved by managing triage and allocation of in-hospital resources for 14 patients or in remote observation of the running scenario on an audiovisual basis.

EVALUATION

After implementation of the pilot MCI simulation-based scenario training, 13 participants completed surveys (48% response rate) including open-ended response items. Quantitative data and open-ended responses using an electronic response system were sequentially analysed to evaluate training feasibility and acceptability.

IMPLICATIONS

We designed a novel simulation-based MCI scenario training focusing on learning objectives involving confidence gain in ED triage. Although this format is extremely resource and time consuming, the highly positive evaluation (participants strongly agreed or agreed that the simulation scenario was suitable for in-hospital MCI triage training) implies that this innovative education technique should be considered for future emergency medical services (EMS) training sessions.

Management of mass casualty incidents: a systematic review and clinical practice guideline update

PURPOSE

Our aim was to generate evidence- and consensus-based recommendations for the management of mass casualty incidents (MCIs) based on current evidence. This guideline topic is part of the 2022 update of the German guideline on the treatment of patients with severe/multiple injuries.

METHODS

MEDLINE and Embase were systematically searched to August 2021. Further literature reports were obtained from clinical experts. Randomised controlled trials, cross-sectional studies, prospective cohort studies, and comparative registry studies were included if they compared triage algorithms, interventions for MCI training, logistics or transport, decontamination, diagnosis or therapy during MCIs in the prehospital and hospital settings. We considered patient-relevant clinical outcomes such as mortality, diagnostic outcomes including sensitivity and specificity, rates of undertriage and overtriage as well as resource use. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength. Population, intervention, comparison, and outcome (PICO) questions from clinical questions were developed by clinical experts and guideline methodologists.

RESULTS

We screened 321 records in the original guideline version and 4225 during this update. Twenty-five studies were included, all of them from the updated search from 2009 to 2021. Twenty-five new studies were identified. Interventions covered were triage training (n = 7 studies), prehospital triage (n = 6), secondary triage (n = 2), transport/logistics (n = 3), decontamination (n = 5), and therapy (n = 2) during MCIs. Three new recommendations were developed. All achieved strong consensus.

CONCLUSION

Due to unsatisfactory evidence, recommendations could only be made on training for improving triage quality and regular exercises for testing a hospital's emergency response plan. No triage algorithm can be scientifically proven to be superior in all aspects. The key recommendation is the following: To improve triage quality, exercises or (virtual) training should be conducted in-house using verified triage systems and algorithms.

A Region-Wide All-Hazard Training Program for Prehospital Mass Casualty Incident Management: A Real-World Case Study

OBJECTIVE

We report the development, implementation, and results of a sustainable region-wide mass-casualty management prehospital training program implemented by the Regione Lombardia emergency medical services (EMS) agency AREU in Italy.

METHODS

The educational program learning objectives are: (1) command and control, communications, and resource management; (2) mass casualty triage and the START triage protocol; (3) on-scene management; (4) Regione Lombardia and AREU Mass Casualty standard operating procedures; and (5) inter-agency communications and relations. For each course edition data on participants' summative assessment, participants' feedback and costs were collected.

RESULTS

Between June 26, 2013, and December 31, 2020, a total of 84 editions of the provider training event were delivered, training an overall 1329 prehospital providers; 1239 (93%) passed the summative assessment and were qualified as being operationally "ready." Regarding participant feedback, the overall program was rated 4.4 ± 0.7 out of 5. The overall cost of running the provider program during the study period was €321 510 (circa US $382 000). The average cost per edition was €3828 and €242 per participant.

CONCLUSIONS

We have described a simple yet interactive simulation and blended-learning approach, which has yielded good pass rates, good participant satisfaction, and contained costs to systematically train emergency medical service personnel.

A Qualitative Assessment of Studies Evaluating the Classification Accuracy of Personnel Using START in Disaster Triage: A Scoping Review

Background

Mass casualty incidents (MCIs) can occur as a consequence of a wide variety of events and often require overwhelming prehospital and emergency support and coordinated emergency response. A variety of disaster triage systems have been developed to assist health care providers in making difficult choices with regards to prioritization of victim treatment. The simple triage and rapid treatment (START) triage system is one of the most widely used triage algorithms; however, the research literature addressing real-world or simulation studies documenting the classification accuracy of personnel using START is lacking.

Aims and Objectives

To explore the existing literature related to the current state of knowledge about studies assessing the classification accuracy of the START triage system.

Design

Scoping review based on Arksey and O'Malley's methodological framework and narrative synthesis based on methods described by Popay and colleagues were performed.

Results

The literature search identified 1,820 citations, of which 32 studies met the inclusion criteria. Thirty were peer-reviewed articles and 28 published in the last 10 years (i.e., 2010 and onward). Primary research studies originated in 13 countries and included 3,706 participants conducting triaging assessments involving 2,950 victims. Included studies consisted of five randomized controlled trials, 17 non-randomized controlled studies, eight descriptive studies, and two mixed-method studies. Simulation techniques, mode of delivery, contextual features, and participants' required skills varied among studies. Overall, there was no consistent reporting of outcomes across studies and results were heterogeneous. Data were extracted from the included studies and categorized into two themes: (1) typology of simulations and (2) START system in MCIs simulations. Each theme contains sub-themes regarding the development of simulation employing START as a system for improving individuals' preparedness. These include types of simulation training, settings, and technologies. Other sub-themes include outcome measures and reference standards.

Conclusion

This review demonstrates a variety of factors impacting the development and implementation of simulation to assess characteristics of the START system. To further improve simulation-based assessment of triage systems, we recommend the use of reporting guidelines specifically designed for health care simulation research. In particular, reporting of reference standards and test characteristics need to improve in future studies.

METASTART: A Systematic Review and Meta-Analysis of the Diagnostic Accuracy of the Simple Triage and Rapid Treatment (START) Algorithm for Disaster Triage

INTRODUCTION

The goal of disaster triage at both the prehospital and in-hospital level is to maximize resources and optimize patient outcomes. Of the disaster-specific triage methods developed to guide health care providers, the Simple Triage and Rapid Treatment (START) algorithm has become the most popular system world-wide. Despite its appeal and global application, the accuracy and effectiveness of the START protocol is not well-known.

OBJECTIVES

The purpose of this meta-analysis was two-fold: (1) to estimate overall accuracy, under-triage, and over-triage of the START method when used by providers across a variety of backgrounds; and (2) to obtain specific accuracy for each of the four START categories: red, yellow, green, and black.

METHODS

A systematic review and meta-analysis was conducted that searched Medline (OVID), Embase (OVID), Global Health (OVID), CINAHL (EBSCO), Compendex (Engineering Village), SCOPUS, ProQuest Dissertations and Theses Global, Cochrane Library, and PROSPERO. The results were expanded by hand searching of journals, reference lists, and the grey literature. The search was executed in March 2020. The review considered the participants, interventions, context, and outcome (PICO) framework and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Accuracy outcomes are presented as means with 95% confidence intervals (CI) as calculated using the binomial method. Pooled meta-analyses of accuracy outcomes using fixed and random effects models were calculated and the heterogeneity was assessed using the Q statistic.

RESULTS

Thirty-two studies were included in the review, most of which utilized a non-randomized study design (84%). Proportion of victims correctly triaged using START ranged from 0.27 to 0.99 with an overall triage accuracy of 0.73 (95% CI, 0.67 to 0.78). Proportion of over-triage was 0.14 (95% CI, 0.11 to 0.17) while the proportion of under-triage was 0.10 (95% CI, 0.072 to 0.14). There was significant heterogeneity of the studies for all outcomes (P < .0001).

CONCLUSION

This meta-analysis suggests that START is not accurate enough to serve as a reliable disaster triage tool. Although the accuracy of START may be similar to other models of disaster triage, development of a more accurate triage method should be urgently pursued.

Preparedness for Mass Casualty Incidents: The Effectiveness of Current Training Model

The importance of MCI organization and training was highlighted by the events of September 11, 2001. Training focuses on the management of physical injuries caused by a single traumatic event over a well-defined, relatively short timeframe. MCI management is integrated into surgical and trauma training, with disaster management training involving the emergency services, law enforcement, and state infrastructure agencies. The COVID-19 pandemic revealed gaps in the preparedness of nation states and global partners in disaster management. The questions that arose include 'has training really prepared us for an actual emergency,' 'what changes need to be made to training to make it more effective,' and 'who else should training be extended to?' This article focuses on the importance of involving multiple sectors in mass casualty training and asks whether greater involvement of non-medical agencies and the public, in operational drills might improve preparedness for global events such as the COVID-19 pandemic.

These guidelines of the European Resuscitation Council (ERC) Cardiac Arrest under Special Circumstances are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. This section provides guidelines on the modifications required for basic and advanced life support for the prevention and treatment of cardiac arrest under special circumstances; in particular, specific causes (hypoxia, trauma, anaphylaxis, sepsis, hypo-/hyperkalaemia and other electrolyte disorders, hypothermia, avalanche, hyperthermia and malignant hyperthermia, pulmonary embolism, coronary thrombosis, cardiac tamponade, tension pneumothorax, toxic agents), specific settings (operating room, cardiac surgery, cardiac catheterization laboratory, dialysis unit, dental clinics, transportation [in-flight, cruise ships], sport, drowning, mass casualty incidents), and specific patient groups (asthma and chronic obstructive pulmonary disease, neurological disease, morbid obesity, pregnancy).

Determination of START triage skill and knowledge levels of Prehospital Emergency Medical Staff: A cross sectional study

BACKGROUND

Emergency medical staff working in pre-hospital (PH-staff) may encounter mass casualty incident (MCI) events. In these events these medical personnel should perform triage. The objective of this study is to determine the skill and knowledge levels of PH-staff about Simple Triage and Rapid Treatment (START) triage.

METHODS

With this cross-sectional, observational study we analyzed data from 127 PH-staff. Data was collected with the survey tool (response rate = 74.7%). Kruskal-Wallis H Test, Mann-Whitney U Test, and Spearman's Correlation analyzes were used in the data analysis by means of SPSS Software.

RESULTS

Of the participants, 63% were men, the median age was 24 years, 88 PH-staff (69.3%) intervened in MCI events, and 37 PH-staff (29.1%) applied START triage. The skill score was 60% and the knowledge score was 72.5%. There was a weak positive correlation between knowledge and skill scores (r = 0.337, p < 0.01). The knowledge level of the emergency medical technicians (EMTs) and paramedics was higher than those from the other professions.

CONCLUSIONS

The triage knowledge and skill levels of the PH-staff were not low contrary to the expectations. The triage knowledge and skill levels of professions that did not have pre-hospital training such as paramedics and EMTs were low.

European Resuscitation Council Guidelines 2021: Cardiac arrest in special circumstances

These European Resuscitation Council (ERC) Cardiac Arrest in Special Circumstances guidelines are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. This section provides guidelines on the modifications required to basic and advanced life support for the prevention and treatment of cardiac arrest in special circumstances; specifically special causes (hypoxia, trauma, anaphylaxis, sepsis, hypo/hyperkalaemia and other electrolyte disorders, hypothermia, avalanche, hyperthermia and malignant hyperthermia, pulmonary embolism, coronary thrombosis, cardiac tamponade, tension pneumothorax, toxic agents), special settings (operating room, cardiac surgery, catheter laboratory, dialysis unit, dental clinics, transportation (in-flight, cruise ships), sport, drowning, mass casualty incidents), and special patient groups (asthma and COPD, neurological disease, obesity, pregnancy).

Edgar Dale's Pyramid of Learning in medical education: Further expansion of the myth

INTRODUCTION

A mythical Pyramid of Learning, usually attributed to Edgar Dale (or the National Training Laboratories [NTL]) and giving student learning retention rates, has been cited in a wide range of educational literature. A 2013 literature review indicated that medical education literature similarly cites this Pyramid. It was hoped that highlighting this myth in that review would reduce references to the Pyramid in future medical education literature. This study aimed at determining what change in Pyramid citation has occurred in the past 5 years.

METHODS

A documented literature review, following the same process as the original review, was conducted. The search dates were September 2012 to April 2018, and the databases were Academic Search Complete, CINAHL, Medline and Google Scholar. Sources were from peer-reviewed journals or conferences, in English.

RESULTS

From an initial search result of 992 documents, 41 were found to match the criteria. Trends discovered are: the number of Pyramid citations in medical education literature is increasing dramatically, new sources of the Pyramid are now being used, refutations of the Pyramid are being used to support it, and even researchers who acknowledge the weakness of the Pyramid still cite it.

DISCUSSION AND CONCLUSION

In spite of the 2013 review, the situation has become worse. One possible reason is that refutations use too polite academic wording, and other researchers then consider the Pyramid to be merely "disputed" or "debated." To kill the myth of the Pyramid, it is necessary for this article's Abstract to state unequivocally: The Pyramid is rubbish, the statistics are rubbish, and they do not come from Edgar Dale. Until the NTL can provide details about the original research, their version must also be treated as rubbish.

Paramedic-Identified Enablers of and Barriers to Pediatric Seizure Management: A Multicenter, Qualitative Study

Background: Seizures have the potential to cause significant morbidity and mortality, and are a common reason emergency medical services (EMS) are requested for a child. An evidence-based guideline (EBG) for pediatric prehospital seizures was published and has been implemented as protocol in multiple EMS systems. Knowledge translation and protocol adherence in medicine can be incomplete. In EMS, systems-based factors and providers' attitudes and beliefs may contribute to incomplete knowledge translation and protocol implementation. Objective: The purpose of this study was to identify paramedic attitudes and beliefs regarding pediatric seizure management and regarding potential barriers to and enablers of adherence to evidence-based pediatric seizure protocols in multiple EMS systems. Methods: This was a qualitative study utilizing semi-structured interviews of paramedics who recently transported actively seizing 0-17 year-old patients in 3 different urban EMS systems. Interviewers explored the providers' decision-making during their recent case and regarding seizures in general. Interview questions explored barriers to and enablers of protocol adherence. Two investigators used the grounded theory approach and constant comparison to independently analyze transcribed interview recordings until thematic saturation was reached. Findings were validated with follow-up member-checking interviews. Results: Several themes emerged from the 66 interviewed paramedics. Enablers of protocol adherence included point-of-care references, the availability of different routes for midazolam and availability of online medical control. Systems-level barriers included equipment availability, controlled substance management, infrequent pediatric training, and protocol ambiguity. Provider-level barriers included concerns about respiratory depression, provider fatigue, preferences for specific routes, febrile seizure perceptions, and inaccurate methods of weight estimation. Paramedics suggested system improvements to address dose standardization, protocol clarity, simplified controlled substance logistics, and equipment availability. Conclusions: Paramedics identified enablers of and barriers to adherence to evidence-based pediatric seizure protocols. The identified barriers existed at both the provider and systems levels. Paramedics identified multiple potential solutions to overcome several barriers to protocol adherence. Future research should focus on using the findings of this study to revise seizure protocols and to deploy measures to improve protocol implementation. Future research should also analyze process and outcome measures before and after the implementation of revised seizure protocols informed by the findings of this study.

Prehospital education in triage for pediatric and pregnant patients in a regional trauma system without collocated pediatric and adult trauma centers

PURPOSE

Patient triage to the appropriate destination is critical to prehospital trauma care. Triage decisions are challenging in a region without collocated pediatric and adult trauma centers.

METHODS

A regional survey was administered to emergency medical response units identifying variability and confusion regarding factors influencing patient disposition. A course was developed to guide the triage of pediatric and pregnant trauma patients. Pre- and posttests were administered to address course principles, including decision making and triage.

RESULTS

A total of 445 participants completed the course at 22 sites representing 88 different prehospital provider agencies. Pre- and posttests were administered to 62% of participants with an average score improvement of 53.4% (pretest range 30% to 56.6%; posttest range 85% to 100%). Improvements were seen in all categories including major and minor trauma in pregnancy, major trauma in adolescence, and knowledge of age limits and triage protocols.

CONCLUSION

Education on triage guidelines and principles of pediatric resuscitation is essential for appropriate prehospital trauma management. Pre- and posttests may be used to demonstrate short term efficacy, while ongoing evaluations of practice patterns and follow-up surveys are needed to demonstrate longevity of acquired knowledge and identify areas of persistent confusion.

Primary mass casualty incident triage: evidence for the benefit of yearly brief re-training from a simulation study

Background

Triage is a mainstay of early mass casualty incident (MCI) management. Standardized triage protocols aim at providing valid and reproducible results and, thus, improve triage quality. To date, there is little data supporting the extent and content of training and re-training on using such triage protocols within the Emergency Medical Services (EMS). The study objective was to assess the decline in triage skills indicating a minimum time interval for re-training. In addition, the effect of a one-hour repeating lesson on triage quality was analyzed.

Methods

A dummy based trial on primary MCI triage with yearly follow-up after initial training using the ASAV algorithm (Amberg-Schwandorf Algorithm for Primary Triage) was undertaken. Triage was assessed concerning accuracy, sensitivity, specificity, over-triage, under-triage, time requirement, and a comprehensive performance measure. A subgroup analysis of professional paramedics was made.

Results

Nine hundred ninety triage procedures performed by 51 providers were analyzed. At 1 year after initial training, triage accuracy and overall performance dropped significantly. Professional paramedic’s rate of correctly assigned triage categories deteriorated from 84 to 71%, and the overall performance score decreased from 95 to 90 points (maximum = 100). The observed decline in triage performance at 1 year after education made it necessary to conduct re-training. A brief didactic lecture of 45 min duration increased accuracy to 88% and the overall performance measure to 97.

Conclusions

To improve disaster preparedness, triage skills should be refreshed yearly by a brief re-education of all EMS providers.

Pre-hospital triage performance after standardized trauma courses

BACKGROUND

The pre-hospital triage process aims at identifying and prioritizing patients in the need of prompt intervention and/or evacuation. The objective of the present study was to evaluate triage decision skills in a Mass Casualty Incident drill. The study compares two groups of participants in Advanced Trauma Life Support and Pre-Hospital Trauma Life Support courses.

METHODS

A questionnaire was used to deal with three components of triage of victims in a Mass Casualty Incident: decision-making; prioritization of 15 hypothetical casualties involved in a bus crash; and prioritization for evacuation. Swedish Advanced Trauma Life Support and Pre-Hospital Trauma Life Support course participants filled in the same triage skills questionnaire just before and after their respective course.

RESULTS

One hundred fifty-three advanced Trauma Life Support course participants were compared to 175 Pre-Hospital Trauma Life Support course participants. The response rates were 90% and 95%, respectively. A significant improvement was found between pre-test and post-test for the Pre-Hospital Trauma Life Support group in regards to decision-making. This difference was only noticeable among the participants who had previously participated in Mass Casualty Incident drills or had experience of a real event (pre-test mean ± standard deviation 2.4 ± 0.68, post-test mean ± standard deviation 2.60 ± 0.59, P = 0.04). No improvement was found between pre-test and post-test for either group regarding prioritization of the bus crash casualties or the correct identification of the most injured patients for immediate evacuation.

CONCLUSIONS

Neither Advanced Trauma Life Support nor Pre-Hospital Trauma Life Support participants showed general improvement in their tested triage skills. However, participation in Mass Casualty Incident drills or experience of real events prior to the test performed here, were shown to be advantageous for Pre-Hospital Trauma Life Support participants. These courses should be modified in order to assure proper training in triage skills.

First Responder Accuracy Using SALT after Brief Initial Training

BACKGROUND

Mass-casualty incidents (MCIs) present a unique challenge with regards to triage as patient volume often outweighs the number of available Emergency Medical Services (EMS) providers. A possible strategy to optimize existing triage systems includes the use of other first responder groups, namely fire and police, to decrease the triage time during MCIs, allowing for more rapid initiation of life-saving treatment and prioritization of patient transport. Hypothesis First-year primary care paramedic (PCP), fire, and police trainees can apply with similar accuracy an internationally recognized MCI triage tool, Sort, Assess, Life-saving interventions, Treatment/transport (SALT), immediately following a brief training session, and again three months later.

METHODS

All students enrolled in the PCP, fire, and police foundation programs at two community colleges were invited to participate in a 30-minute didactic session on SALT. Immediately following this session, a 17-item, paper-based test was administered to assess the students' ability to understand and apply SALT. Three months later, the same test was given to assess knowledge retention.

RESULTS

Of the 464 trainees who completed the initial test, 364 (78.4%) completed the three month follow-up test. Initial test scores were higher (P<.05) for PCPs (87.0%) compared to fire (80.2%) and police (68.0%) trainees. The mean test score for all respondents was higher following the initial didactic session compared to the three month follow-up test (75% vs 64.7%; Δ 10.3%; 95% CI, 8.0%-12.6%). Three month test scores for PCPs (75.4%) were similar to fire (71.4%) students (Δ 4.0%; 95% CI, -2.1% to 10.1%). Both PCP and fire trainees significantly outperformed police (57.8%) trainees. Over-triage errors were the most common, followed by under-triage and then critical errors, for both the initial and follow-up tests.

CONCLUSIONS

Amongst first responder trainees, 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, while critical errors were rare.

Attitudes Towards and Experience of the Use of Triage Tags in Major Incidents: A Mixed Method Study

Introduction

Disaster triage is the allocation of limited medical resources in order to optimize patient outcome. There are several studies showing the poor use of triage tagging, but there are few studies that have investigated the reasons behind this. The aim of this study was to explore 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).

Methods

A mixed method design was used. The first part of the study was in the form of a web-survey of attitudes answered by ambulance personnel. The question explored was: Is it likely that systems that are not used in everyday practice will be used during MIs? Two identical web-based surveys were conducted, before and after implementing a new strategy for triage tagging. This strategy consisted of a time-limited triage routine where ambulance services assigned triage category and applied triage tags in day-to-day trauma incidents in order to improve field triage. The second part comprised three focus group interviews (FGIs) in order to provide a deeper insight into the attitudes towards, and experience of, the use of triage tags. Data were analyzed using qualitative content analysis.

Results

The overall finding was the need for daily routine when failure in practice. Analysis of the web-survey revealed three changes: ambulance personnel were more prone to use tags in minor accidents, the sort scoring system was considered to be more valuable, but it also was more time consuming after the intervention. In the analysis of FGIs, four categories emerged that describe the construction of the overall category: perceived usability, daily routine, documentation, and need for organizational strategies.

Conclusion

Triage is part of the foundation of ambulance skills, but even so, ambulance personnel seldom use this in routine practice. They fully understand the benefit of accurate triage decisions, and also that the use of a triage algorithm and color coded tags is intended to make it easier and more secure to perform triage. However, despite the knowledge and understanding of these benefits, sparse incidents and infrequent exercises lead to ambulance personnel’s uncertainty concerning the use of triage tagging during a MI and will therefore, most likely, avoid using them.

First Responder Accuracy Using SALT during Mass-casualty Incident Simulation

INTRODUCTION

During mass-casualty incidents (MCIs), patient volume often overwhelms available Emergency Medical Services (EMS) personnel. First responders are expected to triage, treat, and transport patients in a timely fashion. If other responders could triage accurately, prehospital EMS resources could be focused more directly on patients that require immediate medical attention and transport.

HYPOTHESIS

Triage accuracy, error patterns, and time to triage completion are similar between second-year primary care paramedic (PCP) and fire science (FS) students participating in a simulated MCI using the Sort, Assess, Life-saving interventions, Treatment/Transport (SALT) triage algorithm.

METHODS

All students in the second-year PCP program and FS program at two separate community colleges were invited to participate in this study. Immediately following a 30-minute didactic session on SALT, participants were given a standardized briefing and asked to triage an eight-victim, mock MCI using SALT. The scenario consisted of a four-car motor vehicle collision with each victim portrayed by volunteer actors given appropriate moulage and symptom coaching for their pattern of injury. The total number and acuity of victims were unknown to participants prior to arrival to the mock scenario.

RESULTS

Thirty-eight PCP and 29 FS students completed the simulation. Overall triage accuracy was 79.9% for PCP and 72.0% for FS (∆ 7.9%; 95% CI, 1.2-14.7) students. No significant difference was found between the groups regarding types of triage errors. Over-triage, under-triage, and critical errors occurred in 10.2%, 7.6%, and 2.3% of PCP triage assignments, respectively. Fire science students had a similar pattern with 15.2% over-triaged, 8.7% under-triaged, and 4.3% critical errors. The median [IQR] time to triage completion for PCPs and FSs were 142.1 [52.6] seconds and 159.0 [40.5] seconds, respectively (P=.19; Mann-Whitney Test).

CONCLUSIONS

Primary care paramedics performed MCI triage more accurately than FS students after brief SALT training, but no difference was found regarding types of error or time to triage completion. The clinical importance of this difference in triage accuracy likely is minimal, suggesting that fire services personnel could be considered for MCI triage depending on the availability of prehospital medical resources and appropriate training.

Improved and sustained triage skills in firemen after a short training intervention

Background

A previous study has shown no measurable improvement in triage accuracy among physicians attending the Advanced Trauma Life Support (ATLS) course and suggests a curriculum revision regarding triage. Other studies have indicated that cooperative learning helps students acquire knowledge.

Objective

The present study was designed to evaluate the effectiveness of trauma cards in triage training for firemen.

Methods

Eighty-six firemen were randomly assigned into two groups: the trauma card group and the direct instruction group. Both groups received the same 30-min PowerPoint lecture on how to perform triage according to the Sort Assess Lifesaving interventions Treatment and transport (SALT) Mass Casualty Triage Algorithm. In the trauma card group, the participants were divided into groups of 3–5 and instructed to triage 10 trauma victims according to the descriptions on the trauma cards. In the direct instruction group, written forms about the same 10 victims were used and discussed as a continuation of the PowerPoint lecture. Total training time was 60 min for both groups. A test was distributed before and after the educational intervention to measure the individual triage skills. The same test was applied again 6 months later.

Results

There was a significant improvement in triage skills directly after the intervention and this was sustained 6 months later. No significant difference in triage skills was seen between the trauma card group and the direct instruction group. Previous experience of multi-casualty incidents, years in service, level of education or age did not have any measurable effects on triage accuracy.

Conclusions

One hour of triage training with the SALT Mass Casualty Triage Algorithm was enough to significantly improve triage accuracy in both groups of firemen with sustained skills 6 months later. Further studies on the first assessment on scene versus patient outcome are necessary to provide evidence that this training can improve casualty outcome. The efficacy and validity of trauma cards for disaster management training need to be tested in future studies.

Edgar Dale's Pyramid of Learning in medical education: a literature review

BACKGROUND

Edgar Dale's Pyramid of Learning and percentages of retained learning are cited in educational literature in a range of disciplines. The sources of the Pyramid, however, are misleading.

AIMS

To examine the evidence supporting the Pyramid and the extent to which it is cited in medical education literature.

METHODS

A review of literature (1946-2012) based on a search utilising Academic Search Complete, CINAHL, Medline and Google Scholar conducted from September to November 2012.

RESULTS

A total of 43 peer-reviewed medical education journal articles and conference papers were found. While some researchers had been misled by their sources, other authors' interpretations of the citations did not align with the content of those citations, had no such citations, had circular references, or consulted questionable sources. There was no agreement on the percentages of learning retention, in spite of many researchers' citing primary texts.

DISCUSSION AND CONCLUSION

The inappropriate citing of the Pyramid and its associated percentages in medical education literature is widespread and continuous. This citing undermines much of the published work, and impacts on research-based medical education literature. While the area of learning/teaching strategies and amount of retention from each is an area for future research, any reference to the Pyramid should be avoided.

Essential key indicators for disaster medical response suggested to be included in a national uniform protocol for documentation of major incidents: a Delphi study

Background

Registration of data from a major incident or disaster serves several purposes such as to record data for evaluation of response as well as for research. Data needed can often be retrieved after an incident while other must be recorded during the incident. There is a need for a consensus on what is essential to record from a disaster response. The aim of this study was to identify key indicators essential for initial disaster medical response registration. By this is meant nationally accepted processes involved, from the time of the emergency call to the emergency medical communication centre until medical care is provided at the emergency department.

Methods

A three round Delphi study was conducted. Thirty experts with a broad knowledge in disaster and emergency response and medical management were invited. In this study we estimated 30 experts to be approximately one third of the number in Sweden eligible for recruitment. Process, structure and outcome indicators for the initial disaster medical response were identified. These were based on previous research and expressed as statements and were grouped into eight categories, and presented to the panel of experts. The experts were instructed to score each statement, using a five point Likert scale, and were also invited to include additional statements. Statements reaching a predefined consensus level of 80% were considered as essential to register.

Results

In total 97 statements were generated, 77 statements reached consensus. The 77 statements covered parts of all relevant aspects involved in the initial disaster medical response. The 20 indicators that did not reach consensus mostly concerned patient related times in hospital, types of support systems and security for health care staff.

Conclusions

The Delphi technique can be used for reaching consensus of data, comprising process, structure and outcome indicators, identified as essential for recording from major incidents and disasters.
