Exploring medical first responders' perceptions of mass casualty incident scenario training: a qualitative study on learning conditions and recommendations for improvement.

OBJECTIVE: Despite participating in scenario training, many medical first responders (MFRs) perceive themselves as inadequately prepared to respond to mass casualty incidents (MCIs). The objective of this study was to conduct a comprehensive examination of traditional MCI scenario training methods, focusing on their inherent strengths and limitations. An investigation into the perceptions of MFRs who had participated in MCI scenario training was carried out to identify potential areas for improvement and provide recommendations for refining MCI training protocols. DESIGN: Qualitative inductive approach using semistructured interviews that took place between October 2021 and February 2022. Data were analysed with qualitative content analysis. SETTING: MCI scenario training involving four organisations (three emergency medical services and one search-and-rescue organisation) tasked with responding to MCIs, collectively representing four European Union countries. PARTICIPANTS: 27 MFRs (17 emergency medical services personnel and 10 search-and-rescue volunteers) were recruited to participate in the study. RESULTS: Two categories and seven associated subcategories (shown in parentheses) were identified as influencing the learning outcomes for MFRs: Training in a context mirroring real-world incidents (conducting incident scene risk assessment, realistic representation in casualties, incorporating scenario variety into the curriculum, interagency collaboration, role alignment when training incident site management) and use of a pedagogical framework (allowing for mistakes, the importance of post-training evaluation). CONCLUSIONS: This study reaffirms the value of traditional MCI scenario training and identifies areas for enhancement, advocating for realistic scenarios, interagency collaboration, improved incident site management skills and thorough post-training evaluation. It suggests a shift in MCI training conceptualisation and delivery. The potential of virtual reality technologies as a valuable addition to training methods is explored, with a note on the need for further research to ascertain the long-term effectiveness of these technologies. However, the selection of a training method should consider programme goals, target population and resources.

The Israeli Trauma system during wartime - policy and management.

On October 7, 2023, Hamas terrorists attacked people in their homes, fields, and at a music festival in Israeli communities near the border with Gaza. More than 1,145 men, women, and children were killed, about 1,800 wounded were evacuated to hospitals in the country, and 253 infants, children, women, elderly, and men were abducted. This mass casualty incident (MCI) was the start of a war that is still ongoing. The Israeli medical system, which faced an overwhelming first 24 h, continues to take care of casualties, including those who are injured by missiles that target Israeli residential areas.Israel has a well-established trauma system, and as a result of the experience gained in this war, the system merited review. This was the topic of a meeting of leaders of the Israeli healthcare system, and it forms the basis of this report. The meeting and report provide a platform for presenting the trauma system management during the war, highlighting the strengths of the system as well as its challenges and lessons learned. The participants also brainstormed and discussed possibilities for future improvements.

Posttraumatic Stress Disorder Among Adults in Communities With Mass Violence Incidents.

Importance: Mass violence incidents (MVIs) are prevalent in the US and can have profound and long-lasting psychological consequences on direct survivors, but their outcomes among the broader communities where the MVI occurred are unknown. Objective: To investigate the prevalence of and factors associated with past-year and current posttraumatic stress disorder (PTSD) among adults in communities that experienced an MVI. Design, Setting, and Participants: This cross-sectional survey was completed between February and September 2020 with a household probability sample of adults from 6 communities that had experienced an MVI between 2015 and 2019: Dayton, Ohio; El Paso, Texas; Parkland, Florida; Pittsburgh, Pennsylvania; San Bernadino, California; and Virginia Beach, Virginia. Address-based sampling was used to identify randomly selected households, mail invitations, and select 1 adult per household to complete a self-administered paper or online survey. Data analysis was performed from September to November 2023. Main Outcomes and Measures: The primary outcome was presumptive diagnostic-level past-year PTSD and current (past month) PTSD determined using American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) PTSD criteria. Results: A total of 6867 adults aged 18 years or older accessed the website with a description of the study and consent materials. Of these, 5991 (87.2%) agreed to participate and completed the survey, 343 (6.3%) partially completed the survey, and 443 (6.5%) did not meet eligibility criteria or refused to participate. Most of the 5991 respondents were female (3825 individuals [53.5%]) and had a mean (SD) age of 45.56 (17.58) years. A total of 1261 of 5931 individuals (21.0%) reported high exposure to the MVI (either they or a close friend and/or family member was on site during the shooting). Nearly one-quarter (23.7%; 1417 of 5977 participants reporting PTSD) met presumptive DSM-5 diagnostic criteria for past-year PTSD, with 8.9% (530 participants) meeting the criteria for current PTSD. Regression analyses found that being female (odds ratio, 2.32; 95% CI, 2.01-2.68) and having a history of both physical or sexual assault and other potentially traumatic events (odds ratio, 9.68; 95% CI, 7.48-12.52) were associated with the greatest risk of past-year PTSD. Conclusions and Relevance: In this survey study of 5991 participants, presumptive PTSD was quite prevalent long after the MVI among adults in communities that have experienced an MVI, suggesting that MVIs have persistent and pervasive public health impacts on communities, particularly among those with prior exposure to physical or sexual assault and other potentially traumatic events. Focusing exclusively on direct exposure to MVIs is not sufficient. Incorporating these findings into screening should improve efforts to identify the individuals most in need of prevention or mental health service after MVIs.

Designing a model of emergency medical services preparedness in response to mass casualty incidents: a mixed-method study.

BACKGROUND: Emergency medical services preparedness in mass casualty incidents is one of the most important concerns in emergency systems. A mass casualty incident is a sudden event with several injured individuals that overwhelms the local health care system. This study aimed to identify and validate the components of emergency medical services readiness in mass casualty incidents which ultimately led to designing a conceptual model. METHODS: This research was an explanatory mixed-method study conducted in five consecutive stages in Iran between November 2021 and September 2023. First, a systematic review was carried out to extract the components of emergency medical services preparedness in mass casualty incidents based on the PRISMA guideline. Second, a qualitative study was designed to explore the preparedness components through in-depth semi-structured interviews and analyzed using the content analysis approach. Third, the integration of the components extracted from the two stages of the systematic review and qualitative study was done by an expert panel. Fourth, the obtained components were validated using the Delphi technique. Two rounds were done in the Delphi phase. Finally, the conceptual model of emergency medical services preparedness in mass casualty incidents was designed by a panel of experts. RESULTS: 10 articles were included in the systematic review stage and sixteen main components were extracted and classified into four categories. In the second stage, thirteen components were extracted from the qualitative study and classified into five categories. Then, the components of the previous two phases were integrated into the panel of experts and 23 components were identified. After validation with the Delphi technique, 22 components were extracted. Lastly, the final components were examined by the panel of experts, and the conceptual schematic of the model was drawn. CONCLUSIONS: It is necessary to have an integrated framework and model of emergency medical service readiness in the planning and management of mass casualty incidents. The components and the final model of this research were obtained after the systematic scientific steps, which can be used as a scheme to improve emergency medical service preparedness in response to mass casualty incidents.

Minimum data set harmonization in the management of cross-border Multi Casualty Incidents. Modified Delphi (VALKYRIES-H2020 project).

INTRODUCTION: There is a need to develop harmonized procedures and a Minimum Data Set (MDS) for cross-border Multi Casualty Incidents (MCI) in medical emergency scenarios to ensure appropriate management of such incidents, regardless of place, language and internal processes of the institutions involved. That information should be capable of real-time communication to the command-and-control chain. It is crucial that the models adopted are interoperable between countries so that the rights of patients to cross-border healthcare are fully respected. OBJECTIVE: To optimize management of cross-border Multi Casualty Incidents through a Minimum Data Set collected and communicated in real time to the chain of command and control for each incident. To determine the degree of agreement among experts. METHOD: We used the modified Delphi method supplemented with the Utstein technique to reach consensus among experts. In the first phase, the minimum requirements of the project, the profile of the experts who were to participate, the basic requirements of each variable chosen and the way of collecting the data were defined by providing bibliography on the subject. In the second phase, the preliminary variables were grouped into 6 clusters, the objectives, the characteristics of the variables and the logistics of the work were approved. Several meetings were held to reach a consensus to choose the MDS variables using a Modified Delphi technique. Each expert had to score each variable from 1 to 10. Non-voting variables were eliminated, and the round of voting ended. In the third phase, the Utstein Style was applied to discuss each group of variables and choose the ones with the highest consensus. After several rounds of discussion, it was agreed to eliminate the variables with a score of less than 5 points. In phase four, the researchers submitted the variables to the external experts for final assessment and validation before their use in the simulations. Data were analysed with SPSS Statistics (IBM, version 2) software. RESULTS: Six data entities with 31 sub-entities were defined, generating 127 items representing the final MDS regarded as essential for incident management. The level of consensus for the choice of items was very high and was highest for the category 'Incident' with an overall kappa of 0.7401 (95% CI 0.1265-0.5812, p 0.000), a good level of consensus in the Landis and Koch model. The items with the greatest degree of consensus at ten were those relating to location, type of incident, date, time and identification of the incident. All items met the criteria set, such as digital collection and real-time transmission to the chain of command and control. CONCLUSIONS: This study documents the development of a MDS through consensus with a high degree of agreement among a group of experts of different nationalities working in different fields. All items in the MDS were digitally collected and forwarded in real time to the chain of command and control. This tool has demonstrated its validity in four large cross-border simulations involving more than eight countries and their emergency services.

Use of Self-Efficacy Scale in Mass Casualty Incidents During Drill Exercises.

INTRODUCTION: Medical First Responders (MFRs) in the emergency department SUMMA 112 are tasked with handling the initial management of Mass Casualty Incidents (MCI) and building response capabilities. Training plays a crucial role in preparing these responders for effective disaster management. Yet, evaluating the impact of such training poses challenges since true competency can only be proven amid a major event. As a substitute gauge for training effectiveness, self-efficacy has been suggested. OBJECTIVE: The purpose of this study is to employ a pre- and post-test assessment of changes in perceived self-efficacy among MFRs following an intervention focused on the initial management of MCI. It also aimed to evaluate a self-efficacy instrument for its validity and reliability in this type of training. METHOD: In this study, we used a pretest (time 1 = T1) - post-test (time 2 = T2) design to evaluate how self-efficacy changed after a training intervention with 201 MFRs in initial MCI management. ANOVA within-subjects and between subjects analyses were used. RESULTS: The findings reveal a noteworthy change in self-efficacy before and after training among the 201 participants. This suggests that the training intervention positively affected participants' perceived capabilities to handle complex situations like MCI. CONCLUSION: The results allow us to recommend a training program with theory components together with practical workshops and live, large-scale simulation exercises for the training of medical first responders in MCI, as it significantly increases their perception of the level of self-efficacy for developing competencies associated with disaster response.

A Statistical Analysis of the Impact of Gun Ownership on Mass Shootings in the USA Between 2013 and 2022.

Mass shootings (incidents with four or more people shot in a single event, not including the shooter) are becoming more frequent in the United States, posing a significant threat to public health and safety in the country. In the current study, we intended to analyze the impact of state-level prevalence of gun ownership on mass shootings-both the frequency and severity of these events. We applied the negative binomial generalized linear mixed model to investigate the association between gun ownership rate, as measured by a proxy (i.e., the proportion of suicides committed with firearms to total suicides), and population-adjusted rates of mass shooting incidents and fatalities at the state level from 2013 to 2022. Gun ownership was found to be significantly associated with the rate of mass shooting fatalities. Specifically, our model indicated that for every 1-SD increase-that is, for every 12.5% increase-in gun ownership, the rate of mass shooting fatalities increased by 34% (p value < 0.001). However, no significant association was found between gun ownership and rate of mass shooting incidents. These findings suggest that restricting gun ownership (and therefore reducing availability to guns) may not decrease the number of mass shooting events, but it may save lives when these events occur.

Medical maximization: The effect of personality on triage decision-making.

Mass Casualty Incidents (MCIs) rapidly overwhelm the ability of local medical resources to deliver comprehensive and definitive medical care and they have been occurring more frequently in recent decades and affect countries of all socioeconomic backgrounds (Hart et al., 2018). As such, it is important to understand how individuals make such decisions in these events and what factors can hinder or help the process. In this study we focused on the critical role of maximization within MCI triage. Triaging an MCI requires juggling the demand and supply of resources, time, and focus, likely leading to various decisions involving compromise/sacrifice. In a vignette study, hosted on Amazon Mturk (n = 235, Mean age = 38.05, 51.49% self-identified as male), which involved triaging over 100 patients we found that trait differences maximization impacted the willingness to use a "black tag". Furthermore, maximization also impacted how much information an individual needed about the patient before being willing to use a black tag. Overall, this research demonstrates the importance of understanding factors that create individual differences in how people make decisions during MCI events, especially those decisions that involve the use of potentially lifesaving treatments.

The role of orthodontics in children identification: a case report of two victims of mass disaster.

INTRODUCTION: Human Identification based on dental evidence cannot be accomplished if antemortem dental records are unavailable or of poor quality. The involvement of the orthodontist in mass disaster victim identification processes may be crucial in relation to the amount and quality of the records which can be obtained before, during, and following the treatment. AIM: The aim of the study is the description of the contribution of the findings drawn from orthodontic records to the identification of victims of mass disasters who had received an orthodontic treatment, through the presentation of two cases. The first case involves the identification of a child victim of a plane crash and the second case involves the identification of two identical twin girls who died in a fire. In both cases, the identification was based on the findings obtained from the ante-mortem records provided by the orthodontist. CONCLUSIONS: The orthodontists apply customized orthodontic appliances and keep a comprehensive file of images, casts, radiographs, and other records in their practice. As a result, they can make a substantial contribution to the identification of young people or even adult victims of mass disasters in any case in which the authorities make a request.

Active shooter in emergency departments in Guanajuato State, Mexico.

Mass violence events, especially in healthcare settings, have devastating consequences and long-lasting effects on the victims and the community. The rate of violent events in Mexico, especially in hospital settings, has increased since 2006, but has become more evident in 2018. Guanajuato State, located in central Mexico, is among the states most affected by the wave of violence, especially active shooter events. The year 2019 had the highest number of incidents. Therefore, the Silver Code and the components of Safe Hospitals, in accordance with the Hartford consensus and PAHO guidelines, were implemented in the hospitals of the Institute of Public Health of the State of Guanajuato, with a focus on the actions of healthcare personnel to prevent collateral damage. Although subsequently there were still fatalities and injuries in the events involving active shooters in the hospitals, there were no casualties among healthcare personnel, according to data from the Institute of Public Health, Guanajuato State. This paper presents information from the data from General Directorate of Epidemiology to describe the hospital mass violence situation in the State of Guanajuato, Mexico and recounts the step taken to effectively manage and prevent these situations moving forward. Specific recommendations based on international consensus and our experience provided include increasing the level of security checks for people entering the hospital premises, training healthcare personnel on violence-related preparedness and improving management of active shooter events consistent with published evidence, to reduce the possibility of casualties.

Defence Engagement (Health) between the UK and Ireland since the Good Friday Agreement in 1998.

This paper describes the range of Defence Engagement (Health) (DE(H)) activities between Northern Ireland and Ireland following the Good Friday Agreement in April 1998. Although the Agreement made provision for cross-border cooperation in health, the Omagh bombing of August 1998 energised the discussion to provide greater co-ordination of future responses to mass casualty events. The paper describes these DE(H) activities at the Strategic, Operational and Tactical levels to show the integration across these levels and between the agencies of both governments. The paper shows how a DE(H) programme can have a successful strategic effect by finding topics of mutual interest that can bring together two countries in order to provide an effective health and social care provision. This paper forms part of a special issue of BMJ Military Health dedicated to Defence Engagement (.

Putting the ready in readiness: A post hoc analysis of surgeon performance during a military mass casualty situation in Afghanistan.

BACKGROUND: All military surgeons must maintain trauma capabilities for expeditionary care contexts, yet most are not trauma specialists. Maintaining clinical readiness for trauma and mass casualty care is a significant challenge for military and civilian surgeons. We examined the effect of a prescribed clinical readiness program for expeditionary trauma care on the surgical performance of 12 surgeons during a 60-patient mass-casualty situation (MASCAL). METHODS: The sample included orthopedic (four) and general surgeons (eight) who cared for MASCAL victims at Hamad Karzai International Airport, Kabul, Afghanistan, on August 26, 2021. One orthopedic and two general surgeons had prior deployment experience. The prescribed program included three primary measures of clinical readiness: 1, expeditionary knowledge (examination score); 2, procedural skills competencies (performance assessment score); and 3, clinical activity (operative practice profile metric). Data were attained from program records for each surgeon in the sample. Each of the 60 patient cases was reviewed and rated (performance score) by the Joint Trauma System's Performance Improvement Branch, a military-wide performance improvement organization. All scores were normalized to facilitate direct comparisons using effect size calculations between each predeployment measure and MASCAL surgical care. RESULTS: Predeployment knowledge and clinical activity measures met program benchmarks. Baseline predeployment procedural skills competency scores did not meet program benchmarks; however, those gaps were closed through retraining, ensuring all surgeons met or exceeded the program benchmarks predeployment. There were very large effect sizes (Cohen's d ) between all program measures and surgical care score, confirming the relationship between the program measures and MASCAL trauma care provided by the 12 surgeons. CONCLUSION: The prescribed program measures ensured that all surgeons achieved predeployment performance benchmarks and provided high-quality trauma care to our nation's service members. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Training for a mass casualty incident: Conception, development, and implementation of a crew-resource management course for forward surgical teams.

BACKGROUND: Since 2021, the predeployment training of French FSTs has included a simulation-based curriculum consisting of organizational and human factors. The purpose of this article is to describe the development of a crew-resource management (CRM) training course dedicated for the forward surgical teams (FSTs) of the French Military Health Service. METHODS: The approach was based on three steps: (1) establishment of a conceptual framework of FSTs deployment; (2) development of an aircrew-like CRM training combining lectures, laboratory exercises, and situational training exercises to consider four fundamental "nontechnical" (cognitive and social) skills for effective and safe combat casualty care: (a) leadership, (b) decision-making, (c) coordination, and (d) situational awareness; (3) Implementation of teamwork evaluation tools. RESULTS: A multidisciplinary team designed a conceptual framework for FST preparedness, 24 French FSTs completed a high-quality training that takes into account both technical and nontechnical skills to maintain quality of combat care during mass-casualty incidents, FSTs' CRM skills were assessed using an audio/video recording of a simulated mass-casualty incident.

Evaluation of urological and gynecological surgeons as force multipliers for mass casualty trauma care.

BACKGROUND: The clinical demands of mass casualty events strain even the most well-equipped trauma centers and are especially challenging in resource-limited rural, remote, or austere environments. Gynecologists and urologists care for patients with pelvic and abdominal injuries, but the extent to which they are able to serve as "force multipliers" for trauma care is unclear. This study examined the abilities of urologists and gynecologists to perform 32 trauma procedures after mentored training by expert trauma educators to inform the potential for these specialists to independently care for trauma patients. METHODS: Urological (6), gynecological surgeons (6), senior (postgraduate year 5) general surgery residents (6), and non-trauma-trained general surgeons (8) completed a rigorous trauma training program (Advanced Surgical Skills Exposure in Trauma Plus). All participants were assessed in their trauma knowledge and surgical abilities performing 32 trauma procedures before/after mentored training by expert trauma surgeons. Performance benchmarks were set for knowledge (80%) and independent accurate completion of all procedural components within a realistic time window (90%). RESULTS: General surgery participants demonstrated greater trauma knowledge than gynecologists and urologists; however, none of the specialties reached the 80% benchmark. Before training, general surgery, and urology participants outperformed gynecologists for overall procedural abilities. After training, only general surgeons met the 90% benchmark. Post hoc analysis revealed no differences between the groups performing most pelvic and abdominal procedures; however, knowledge associated with decision making and judgment in the provision of trauma care was significantly below the benchmark for gynecologists and urologists, even after training. CONCLUSION: For physiologically stable patients with traumatic injuries to the abdomen, pelvis, or retroperitoneum, these specialists might be able to provide appropriate care; however, they would best benefit trauma patients in the capacity of highly skilled assisting surgeons to trauma specialists. These specialists should not be considered for solo resuscitative surgical care. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

What If Nice Terrorist Attack Would Have Happened in Milan? Drawing a Disaster Plan for Mass Casualty Incidents Involving the Pediatric Population.

Terrorist attacks involving children raised concern regarding the preparedness to treat pediatric trauma patients during mass casualty incidents (MCIs). The purpose of this project was to assess the resources available in Milan to respond to MCIs as the 2016 Bastille Day attack in Nice. Literature and guidelines were reviewed and minimal standard requirements of care of pediatric trauma patients in MCIs were identified. The hospitals that took part in the study were asked to answer a survey regarding their resource availability. An overall surge capability of 40-44 pediatric trauma patients was identified, distributed based on age and severity, hospital resources, and expertise. The findings showed that adult and pediatric hospitals should work in synergy with pediatric trauma centers, or offer an alternative if there is none, and should be included in disaster plans for MCIs. Simulations exercises need to be carried out to evaluate and validate the results.

Developing emotional preparedness and mental resilience through high-fidelity simulation: a 'bridge too far' for institutions teaching major trauma management and mass-casualty medicine?

BACKGROUND: Clinical acumen represents only part of being adequately equipped to attend a major incident. The emotive sights, sounds and smells of these dynamic environments are all-encompassing experiences, and responders must also be armed with the emotional preparedness to perform their clinical or managerial duties effectively, as well as the mental resilience to facilitate professional continuance. Despite this, limited training and a sparsity of evidence exists to guide developments within this domain. Historically, major incident training has focused on clinical theory acquisition, but irrespective of how comprehensive the learning materials, they are of little consequence if tandem steps to cultivate mental resilience and emotional preparedness are absent. High-Fidelity Simulation (HFS) has a growing reputation as an effective means of bridging important gaps between theory and practice. This pilot study aimed to measure student's self-reported perception of their readiness to respond to a major incident following a large-scale HFS. METHODS: Quantitative data was obtained from a sample of 108 students undertaking paramedic science, physician associate studies and adult nursing degree programmes. A bespoke questionnaire was developed to measure self-reported clinical acumen, mental and emotional preparedness. RESULTS: 91% of students agreed the combination of theoretical training and HFS provided made them feel clinically prepared to attend a real major incident; 86% agreed this experience had developed their mental resilience and 90% agreed that they felt emotionally prepared to attend a major incident. CONCLUSION: Within this pilot study, the blend of theoretical training and HFS contributed to self-reported clinical acumen, mental and emotional preparation, in learners training to work in disaster environments or emergency medicine settings.
