The Challenge of Mass Casualty Incident Response Simulation Exercise Design and Creation: A Modified Delphi Study.

BACKGROUND: A Mass Casualty Incident response (MCI) full scale exercise (FSEx) assures MCI first responder (FR) competencies. Simulation and serious gaming platforms (Simulation) have been considered to achieve and maintain FR competencies. The translational science (TS) T0 question was asked: how can FRs achieve similar MCI competencies as a FSEx through the use of MCI simulation exercises? METHODS: T1 stage (Scoping Review): PRISMA-ScR was conducted to develop statements for the T2 stage modified Delphi (mD) study. 1320 reference titles and abstracts were reviewed with 215 full articles progressing for full review leading to 97 undergoing data extraction.T2 stage (mD study): Selected experts were presented with 27 statements derived from T1 data with instruction to rank each statement on a 7-point linear numeric scale, where 1 = disagree and 7 = agree. Consensus amongst experts was defined as a standard deviation ≤ 1.0. RESULTS: After 3 mD rounds, 19 statements attained consensus and 8 did not attain consensus. CONCLUSIONS: MCI simulation exercises can be developed to achieve similar competencies as FSEx by incorporating the 19 statements that attained consensus through the TS stages of a scoping review (T1) and mD study (T2), and continuing to T3 implementation, and then T4 evaluation stages.

Novel design of inspiratory flow generation and gas mixing for critical care ventilators suitable for rapid production and mass casualty incidents.

Scarcity of medical resources inspired many teams worldwide to design ventilators utilizing different approaches during the recent COVID-19 pandemic. Although it can be relatively easy to design a simple ventilator in a laboratory, a large scale production of reliable emergency ventilators which meet international standards for critical care ventilators is challenging and time consuming. The aim of this study is to propose a novel and easily manufacturable principle of gas mixing and inspiratory flow generation for mechanical lung ventilators. Two fast ON/OFF valves, one for air and one for oxygen, are used to control the inspiratory flow generation using pulse width modulation. Short gas flow pulses are smoothed by low-pass acoustic filters and do not propagate further into the patient circuit. At the same time, the appropriate pulse width modulation of both ON/OFF valves controls the oxygen fraction in the generated gas mixture. Tests focused on the accuracy of the delivered oxygen fractions and tidal volumes have proved compliance with the international standards for critical care ventilators. The concept of a simple construction using two fast ON/OFF valves may be used for designing mechanical lung ventilators and thus suitable for their rapid production during pandemics.

Mass casualty incidents during the ten years of telemedical maritime assistance service in Gdynia, Poland.

Mass casualty incident (MCI) is one of the most difficult situation in emergency medicine. Due to the specific conditions, MCIs occurring at sea are usually far more demanding than those happening on land. In this paper the authors would like to describe the MCIs, which have happened during almost 10 years of functioning of the Polish Telemedical Maritime Assistance Service (TMAS). First incident concerned a group of migrants floating on a raft on the Gulf of Mexico. The cause of the second incident was acute organophosphate intoxication among the crew of the merchant ship. The third incident was triggered by the coronavirus disease 2019 (COVID-19). It is important to emphasize, that triage system may help in proper management of MCIs. Cooperation of the medical services, such as TMAS, local emergency medical staff, Search and Rescue (SAR) service and military force seems to be crucial in MCI managements occuring at sea. In case of any doubts, change of a course and heading to the nearest port or immediate evacuation should be taken into consideration. The authors believe that analysis of these incidents may help TMAS personnel all over the world to handle MCIs in the future. Med Pr. 2023;74(2):145-50.

Extended reality as a training method for medical first responders in mass casualty incidents: A protocol for a systematic review.

INTRODUCTION/BACKGROUND: Mass-casualty incidents (MCIs) and disasters require an organised and effective response from medical first responders (MFRs). As such, novel training methods have emerged to prepare and adequately train MFRs for these challenging situations. Particular focus should be placed on extended reality (XR), which encompasses virtual, augmented and mixed reality (VR, AR, and MR, respectively), and allows participants to develop high-quality skills in realistic and immersive environments. Given the rapid evolution of high-fidelity simulation technology and its advantages, XR simulation has become a promising tool for emergency medicine. Accordingly, this systematic review aims to: 1) evaluate the effectiveness of XR training methods and 2) explore the experience of MFRs undergoing such training. METHODS: A comprehensive search strategy will encompass four distinct themes: MFRs, disasters/MCIs, education and simulation, and XR. Four databases (MEDLINE, EMBASE, CINAHL and LILACs) will be searched along with an in-depth examination of the grey literature and reference lists of relevant articles. MetaQAT will be used as a study quality assessment tool and integrated into Covidence as part of the data extraction form. Given the predicted high heterogeneity between studies, it may not be possible to standardise data for quantitative comparison and meta-analysis. Thus, data will be synthesised in a narrative, semi-quantitative manner. DISCUSSION: This review will examine the existing literature on the effectiveness of XR simulation as a tool to train MFRs for MCIs, which could ultimately improve preparedness and response to disasters. TRIAL REGISTRATION: Protocol registration: PROSPERO CRD42021275692.

Beirut Blast: The Experiences of Acute Care Hospitals.

Mass Casualty Incidents recently increased in intensity and frequency at an unprecedented rate globally. On August 4, 2020, a massive blast hit the Port of Beirut severely damaging its healthcare sector. This study aims to provide a comprehensive understanding of the impact of the Beirut blast on acute care hospitals in the Beirut area, with a focus on understanding healthcare professionals' (HCPs) responses and encountered challenges. A qualitative research design method was adopted to evaluate the experiences of HCPs at acute hospitals located within 5 kilometers of the blast epicenter. 9 hospitals participated in the study. 11 semi-structured interviews were conducted with key informant HCPs using a designed interview guide. HCPs reported severe infrastructural damages in their corresponding hospitals, and 2 were completely non-functional post-blast. Other than physical injuries sustained by HCPs, the blast imposed substantial strains on their mental health, exacerbated by the ongoing socio-economic crises in Lebanon. Moreover, the findings revealed critical challenges which hindered hospitals' emergency responses at the level of communication, coordination, and human resources, as well as supplies. Participants urged for the need to conduct proper triage, arrange emergency operating centers, and deploy outdoor treatment tents among others, to effectively respond to future disasters. The Beirut blast overwhelmed the Lebanese healthcare system and challenged its level of emergency preparedness. This generated evidence to address the deficiencies and strengthen the existing hospitals' emergency response plans. Future efforts should include prioritizing hospitals' emergency preparedness to ensure the provision of care at increased capacity following the impact of a large-scale disaster.

A Scoping Review of Pediatric Mass-Casualty Incident Triage Algorithms.

OBJECTIVE: For the pediatric population, there is no consensus on which triage system to use for mass-casualty incidents (MCI). A scoping review was conducted to identify the most accurate triage system for pediatric patients in MCIs. METHODS: MEDLINE (NLM, Bethesda, MA, USA), Embase (Elsevier Inc., Amsterdam, Netherlands), CINAHL (EBSCO Information Services, Ipswitch, MA, USA), and The Cochrane CENTRAL Register of Controlled Trials (John Wiley & Sons, Hoboken, NJ, USA), as well as Scopus (Elsevier Inc., Amsterdam, Netherlands), Global Health (Centre for Agriculture and Bioscience International, Wallingford, UK), Global Health Archive (Centre for Agriculture and Bioscience International, Wallingford, UK), and Global Index Medicus (World Health Organization, Geneva, Switzerland) were searched for relevant studies that were divided into 3 categories: accuracy of a single system, comparison of 2 or more primary triage system and comparison of secondary triage systems. Grey literature was also searched. RESULTS: 996 studies were identified from which 18 studies were included. Systems studied were found to have poor inter-rater reliability, had a low level of agreement between providers, had missed critically ill patients or were not externally validated. 11 studies compared pediatric MCI triage algorithms using different strategies and the most accurate algorithm was not identified. A recently developed secondary triage system, specifically for pediatric patients, was found to perform better than the comparison triage system. CONCLUSION: Although some algorithms performed better than others, no primary triage algorithm was accurate enough for the pediatric population. However, only 1 secondary triage algorithm was found to be superior to the others.

Optimization of a Patient Distribution Framework: Second Wave COVID-19 Preparedness and Challenges in the Amsterdam Region.

To meet surge capacity and to prevent hospitals from being overwhelmed with COVID-19 patients, a regional crisis task force was established during the first pandemic wave to coordinate the even distribution of COVID-19 patients in the Amsterdam region. Based on a preexisting regional management framework for acute care, this task force was led by physicians experienced in managing mass casualty incidents. A collaborative framework consisting of the regional task force, the national task force, and the region's hospital crisis coordinators facilitated intraregional and interregional patient transfers. After hospital admission rates declined following the first COVID-19 wave, a window of opportunity enabled the task forces to create, standardize, and optimize their patient transfer processes before a potential second wave commenced. Improvement was prioritized according to 3 crucial pillars: process standardization, implementation of new strategies, and continuous evaluation of the decision tree. Implementing the novel "fair share" model as a straightforward patient distribution directive supported the regional task force's decisionmaking. Standardization of the digital patient transfer registration process contributed to a uniform, structured system in which every patient transfer was verifiable on intraregional and interregional levels. Furthermore, the regional task force team was optimized and evaluation meetings were standardized. Lines of communication were enhanced, resulting in increased situational awareness among all stakeholders that indirectly provided a safety net and an improved integral framework for managing COVID-19 care capacities. In this article, we describe enhancements to a patient transfer framework that can serve as an exemplary system to meet surge capacity demands during current and future pandemics.

Emergency Medical Services Preparedness in Dual Disasters: War in the Era of COVID-19 in Armenia.

INTRODUCTION: Emergency Medical Services (EMS) is a critical part of Disaster Medicine and has the ability to limit morbidity and mortality in a disaster event with sufficient training and experience. Emergency systems in Armenia are in an early stage of development and there is no Emergency Medicine residency training in the country. As a result, EMS physicians are trained in a variety of specialties.Armenia is also a country prone to disasters, and recently, the Armenian EMS system was challenged by two concurrent disasters when the 2020 Nagorno-Karabakh War broke out in the midst of the SARS-CoV-2/coronavirus disease 2019 (COVID-19) pandemic. STUDY OBJECTIVE: This study aims to assess the current state of disaster preparedness of the Armenian EMS system and the effects of the simultaneous pandemic and war on EMS providers. METHODS: This was a cross-sectional study conducted by anonymous survey distributed to physicians still working in the Yerevan EMS system who provided care to war casualties and COVID-19 patients. RESULTS: Survey response rate was 70.6%. Most participants had been a physician (52.1%) or EMS physician (66.7%) for three or less years. The majority were still in residency (64.6%). Experience in battlefield medicine was limited prior to the war, with the majority reporting no experience in treating mass casualties (52.1%), wounds from explosives (52.1%), or performing surgical procedures (52.1%), and many reporting minimal to no experience in treating gunshot wounds (62.5%), severe burns (64.6%), and severe orthopedic injuries (64.6%). Participants had moderate experience in humanitarian medicine prior to war. Greater experience in battlefield medicine was found in participants with more than three years of experience as a physician (z-score -3.26; P value <.01) or as an EMS physician (z-score -2.76; P value <.01) as well as being at least 30 years old (z-score -2.11; P value = .03). Most participants felt they were personally in danger during the war at least sometimes (89.6%). CONCLUSION: Prior to the COVID-19 pandemic and simultaneous 2020 Nagorno-Karabakh War, EMS physicians in Armenia had limited training and experience in Disaster Medicine. This system, and the frontline physicians on whom it relies, was strained by the dual disaster, highlighting the need for Disaster Medicine training in all prehospital medical providers.

[Management of Clinical Capacity Overload Due to Mass Patient Influx]. / Management einer klinischen Kapazitätenüberlastung durch Massenanfall von Patienten.

Hospitals play a crucial role in the management of large-scale emergencies or disasters. This has been clearly demonstrated by the recent terrorist attacks in Europe, by the SARS-CoV-2 pandemic, and currently by the Ukraine war. In order to cope with extraordinary situations and large-scale emergencies, such as mass casualty incidents, hospitals need to be prepared in detail - by preparing and implementing a hospital contingency plan. The article presented here describes in hospital preparation for a mass casualty incident.

Strengthening Emergency Department Resiliency - Resident Deployment Considerations during a Mass-Casualty Incident.

In the event of a mass-casualty incident (MCI), hospital emergency departments (EDs) may be called upon to provide care to a large number of critically ill patients. As EDs plan for MCIs, determining how to best allocate staff members can play a significant role in the success or failure of a response. In academic EDs, a group that is often overlooked during MCI planning is the resident physicians. We argue that MCI plans at academic hospitals should consider the re-deployment of emergency medicine resident physicians in non-critical hospital rotations back to the ED.

Response to Mass-Casualty Incidents and Outbreaks: A Prehospital Disaster Training Package Developed for the National Emergency Medical Service in Sierra Leone.

Sierra Leone is a country highly prone to disasters, still recovering from the catastrophic 2014 Ebola epidemic. In 2018, the country launched its first National Emergency Medical Service (NEMS) aiming to strengthen the provision of essential health services to the population with the long-term goal of creating a resilient health system able to effectively respond to and recover from emergencies. The Center for Research and Training in Disaster Medicine, Humanitarian Aid, and Global Health (CRIMEDIM), together with the Italian NGO Doctors with Africa (CUAMM), under the direct supervision of the Ministry of Health and Sanitation (MoHS), developed a prehospital Disaster Training Package (DTP) to be delivered to all NEMS personnel to boost the prehospital management of mass-casualty incidents (MCIs) and outbreaks. The DTP included a first phase in which NEMS local trainers underwent a training-of-trainers (ToT) course, enabling them to deliver cascade trainings to 16 district ambulance supervisors, 441 paramedics, 441 ambulance drivers, and 36 operators working in the NEMS operation center. This on-going training package represents the first Disaster Medicine training course for prehospital health professionals in Sierra Leone.

Challenges in managing, sustaining, and assessing closed point of dispensing sites: Findings from a qualitative study.

Most U.S. public health agencies rely upon closed points of dispensing (PODs) to aid in medical countermeasure (MCM) distribution. However, few studies have focused on how to assess closed POD preparedness and none have examined best practices for managing sites once they have been recruited. This study involved qualitative interviews with U.S. disaster planners to elucidate their approaches and challenges to managing, sustaining, and assessing existing closed POD sites. In all, 16 disaster planners participated. Common management practices included frequent communication with sites, providing formal and informal training, and assisting with POD exercises. Very few jurisdictions reported doing formal assessments of closed POD sites. The largest challenges identified were staff turnover and keeping sites engaged, sometimes leading to sites voluntarily withdrawing or needing to be removed from being a closed POD. Frequent communication and building partnerships with closed POD site personnel were recommended to maintain and sustain existing sites. Formal and informal assessments will provide assurance of deployment readiness. Closed POD management is a challenging, but essential process to ensure readiness to deploy. Practices outlined by this study can be implemented to enhance closed POD network management at other jurisdictions. This should increase the ability to distribute MCMs rapidly during a future event, contributing to stronger community resilience. Public health officials should continue expanding and improving closed POD networks to enable MCM delivery and minimize morbidity and mortality related to mass casualty events.

Implementation of a unique mass casualty and emergency preparedness longitudinal learning experience for postgraduate year 2 pharmacy residents.

BACKGROUND AND PURPOSE: The American Society of Health-System Pharmacists (ASHP) postgraduate year 2 (PGY2) critical care pharmacy residency program offers an elective competency area, E3: Mass Casualty. Similar elective competencies are also available for PGY2 emergency medicine and postgraduate year 1/2 pharmacotherapy programs. Because of the COVID-19 pandemic, pharmacist proficiency in the management of disasters is even more urgent. However, few residency programs require or include a specific learning experience to achieve this competency. This article provides examples of opportunities that residency programs can implement to offer an Emergency Preparedness/Mass Casualty (EP/MC) learning experience. EDUCATIONAL ACTIVITY AND SETTING: A longitudinal EP/MC learning experience was integrated into a PGY2 critical care program. FINDINGS: A longitudinal EP/MC learning experience within the PGY2 critical care, emergency medicine, and pharmacotherapy residency program curricula is achievable and promotes resident development. Learning experience components included topic discussions, participation on local and state-level emergency preparedness (EP) committees, completion of certification programs, projects, and participation on statewide emergency response teams. SUMMARY: Implementation of a longitudinal EP/MC learning experience formalizes topics and activities that support achievement of the ASHP elective competency area of Mass Casualty for PGY2 residency programs. EP/MC goals and objectives should be a requirement for critical care, emergency medicine, pharmacotherapy, and health-system pharmacy administration and leadership PGY2 programs. By formalizing training, pharmacists can be better prepared for EP and more integrated into multidisciplinary disaster response teams.

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.

Disasters on campus: A cross-sectional survey of college EMS systems' preparedness to respond to mass casualty incidents.

OBJECTIVE: The objective of this study was to assess the training and readiness levels of Collegiate Emergency Medical Service (EMS) providers to respond to mass casualty incidents (MCIs). METHODS: An anonymous cross-sectional survey of Collegiate EMS providers was performed. PARTICIPANTS: Participants were US-based EMS providers affiliated with the National Collegiate Emergency Medical Services Foundation. OUTCOME MEASURES: The main outcome measures were levels of EMS experience and MCI training, subjective readiness levels for responding to various MCI scenarios, and analyzing the effect of the COVID-19 pandemic on MCI response capabilities. RESULTS: Respondents had a median age of 21 years (interquartile range IQR 20, 22), with 86 percent (n = 96/112) being trained to the Emergency Medical Technician-Basic level. Providers reported participating in an average of 1.6 MCI trainings over the last four years (IQR, 1.0, 2.2). Subjective MCI response readiness levels were highest with active assailant attacks followed by large event evacuations, natural disasters, hazardous material (HAZMAT) incidents, targeted automobile ramming attacks, explosions, and finally bioweapons release. Disparate to this, only 18 percent of participants reported training in the fundamentals of tactical and disaster medicine. With respect to the effect of the COVID-19 pandemic on MCI readiness, 27 percent of respondents reported being less prepared, and there was a statistically significant decrease in subjective readiness to respond to HAZMAT incidents. CONCLUSION: Given low rates of MCI training but high rates of self-assessed MCI preparedness, respondents may overestimate their readiness to adequately respond to the complexity of a real-world MCI. More objective assessment measures are needed to evaluate provider preparedness.

Developing pre-registration nurses' resilience to mass casualty situations through the pedagogy of simulation.

Simulation has become a core component of nursing curricular worldwide. Within a three-year, pre-registration degree typically students would not be exposed to disaster type situations and it was believed that a well-coordinated simulation exercise could replicate this. It was hoped that the simulation would require students to think quickly on their feet and transfer acquired skills. Worldwide disasters including the current novel coronavirus have, heightened the need for well-prepared resilient health professionals capable of responding to many different types of emergencies including mass casualty situations. The simulated event involved 80 adult field student nurses, 19 probationer police officers, 6 photojournalism students, 2 Welsh Ambulance paramedics, 5 staff from 203 Field Hospital, 2 St John Cymru Wales Officers, 1 community first responder and 6 Fire and Rescue personnel. All these individuals came together to undertake a simulated emergency response to a mass casualty incident. Behaviours and clinical skills were observed throughout the event along with interprofessional interactions.

The Public Health Role of Medical Examiner Offices During COVID-19 and Other Mass Fatality Events.

ABSTRACT: The public health role of a medical examiner office (MEO) in a pandemic is largely undefined; however, death data may be useful in strategic planning. Deaths reportable to MEO are defined in statute, with discretion as to the assumption of jurisdiction. We analyzed the daily reported death numbers (DRDNs) in our jurisdiction from March 1, 2020, to March 31, 2021, and compared them with hospital admission and COVID-19 fatality data over the same period. The DRDN from an MEO is easily obtained and may be useful as a supplemental and surrogate metric in certain pandemic mass casualty decisions. Hospital admission data were analyzed in real time and with a 2-week time-shift, as deaths lag hospital admissions as a disease surveillance metric. Moderate correlation was observed between DRDN and hospital admissions (r = 0.570), and this improved to strong correlation (0.645) when the 2-week time-shift was incorporated into the analysis. Both evaluations were statistically significant (P < 0.0001). The DRDN also moderately correlated (r = 0.412) with the number of COVID-19 deaths. Because death certification and hospital diagnosis may be delayed, real-time trend recognition in a pandemic may benefit from use of DRDN from MEO.

Preparing for mass casualty events despite COVID-19.

Preparedness for mass casualty events is essential at local, national, and global levels. Much more needs to be done by all stakeholders to avoid unnecessary morbidity and mortality despite the challenges that COVID-19 continues to present. In this editorial, we highlight the challenges and solutions for mass casualty incident preparations.
