Pediatric disaster preparedness curriculum across emergency medicine residencies.

OBJECTIVE: To assess pediatric disaster medicine (PDM) instruction in emergency medicine (EM) residency programs and to identify barriers to integrating these skills into EM training. METHODS: National survey study of United States EM Residency Program Directors (PDs) and Assistant PDs during the 2021-2022 academic year. RESULTS: Of the 186 EM residency programs identified, a total of 24 responses were recorded with a response rate of 12.9 percent. Importance of training was rated 5.79 (standard deviation 2.51) using the Likert scale ranging from 1 to 10. Out of 24 programs, 17 (70.8 percent) do not have any PDM training as part of residency training. Live drill, simulation, and tabletop were identified as most effective methods to deliver PDM training with the Likert scale score of 4.78, 4.6, and 4.47, respectively. Senior trainees' level of -knowledge/skills with family reunification (Likert 2.09/5; chemical-biological-radiological-nuclear explosive 2.95/5) and mass casualty preparation of the emergency department (3.3/5) as assessed by the respondents. The main barrier to education included logistics, eg, space and costs (Likert 3.7/5), lack of didactic time (3.7/5), and limited faculty knowledge, skill, or experience (3.3/5). CONCLUSION: PDM training is lacking and requires standardization. This study highlights the opportunity for the creation of a model for EM resident education in PDM.

Managing CBRN mass casualty incidents at hospitals-Find a simple solution for a complex problem: A pilot study.

OBJECTIVE: Chemical, biological, radiological, and nuclear (CBRN) incidents are a major challenge for emergency medical services and the involved hospitals, especially if decontamination needs to be performed nearby or even within the hospital campus. The University Hospital Wuerzburg has developed a comprehensive and alternative CBRN response plan. The focus of this study was to proof the practicability of the concept, the duration of the decontamination process, and the temperature management. METHODS: The entire decontamination area can be deployed 24/7 by the hospitals technical staff. Fire and rescue services are responsible for the decontamination process itself. This study was designed as full-scale exercise with 30 participants. RESULTS: The decontamination area was ready for operation within 30 minutes. The decontamination of the four simulated patients took 5.5 ± 0.6 minutes (mean ± SD). At the end of the decontamination process, the temperature of the undressed upper body of the training patients was 27.25 ± 1°C (81.05 ± 2°F) (mean ± SD) and the water in the shower was about 35°C (95°F). CONCLUSION: The presented concept is comprehensive and simple for a best possible care during CBRN incidents at hospitals. It ensures wet decontamination by Special Forces, while the technical requirements are created by the hospital.

Digital Response to Physical Crises: The Role of an E-Health Platform in the 2023 Southern Turkey Earthquakes.

The catastrophic earthquakes that struck Southern Turkey in 2023 highlighted the pressing need for effective disaster management strategies. The unprecedented scale of the crisis tested the robustness of traditional healthcare responses and highlighted the potential of e-health solutions. Despite the deployment of Emergency Medical Teams, initial responders - primarily survivors of the earthquakes - faced an enormous challenge due to their lack of training in mass-casualty situations. An e-health platform was introduced to support these first responders, offering tools for drug calculations, case management guidelines, and a deep learning model for pediatric X-ray analysis. This commentary presents an analysis of the platform's use and contributes to the growing discourse on integrating digital health technologies in disaster response and management.

Long-Term Tissue Preservation at Ambient Temperature for Post-Mass Fatality Incident DNA-Based Victim Identification.

In a mass fatality incident (MFI), effective preservation of tissue samples is the cornerstone for downstream DNA-based identification of victims. This is commonly achieved through freezing of tissue samples excised from bodies/fragmented remains which may be buried or stored in refrigerated containers. This may, however, not be possible depending on the nature of the MFI; in particular, during armed conflict/war where extended periods of electrical outages would be expected. The present study compared the effectiveness of long-term tissue preservation at ambient temperatures using two commercial products (non-iodized kitchen salt and a 40% alcoholic beverage) against a chemical preservative (Allprotect™ Tissue Reagent (Qiagen, Germantown, MD, USA)) and freezing at -20 °C. Bovine muscle tissue, used as a proxy for human tissue, was treated with the four preservation methods and sampled at six different time-points over a 24-month period. All four methods were able to preserve the bovine tissue, generally yielding STR-PCR (Short Tandem Repeat-Polymerase Chain Reaction) amplicons > 200 bp in size even at the end of 24 months. Gel electrophoresis, however, indicated that salt was more effective in preserving DNA integrity with high-molecular-weight DNA clearly visible as compared to the low-molecular-weight DNA smears observed in the other methods. This study also proposes a simple process for the rapid and low-cost preservation of tissue samples for long-term storage at ambient temperatures in support of post-incident victim identification efforts.

Managing a Mega Mass Casualty Event by a Civilian Emergency Medical Services Agency: Lessons From the First Day of the 2023 Hamas-Israel War.

On 7 October 2023, Israel faced an unexpected attack by Hamas, causing over 1,200 deaths and injuring more than 9,000 individuals. This report delves into the rapid medical response spearheaded by Israel's civilian Emergency Medical Service, Magen David Adom (MDA), during this crisis. Utilizing data from MDA's electronic database, 4,097 dispatch records from the day were analyzed. Of these, 39.3% were directly related to the attack. EMS teams faced multiple challenges, including handling an overwhelming number of casualties and navigating active combat zones, which impeded safe access to victims, posed significant risks to teams' safety, and constrained patient evacuation strategies. This incident underscores the importance of reinforcing healthcare resilience, particularly emphasizing the need for centralizing various aspects of response efforts. These include streamlined communication, national coordination of pre-hospital resources, and systemic management of patient evacuations. Moreover, providing substantial support for EMS personnel, who operated in highly challenging conditions, is imperative.

Evaluating emergency response at a hospital near the Gaza border within 24 h of increased conflict.

BACKGROUND: Frontline hospitals near active hostilities face unique challenges in delivering emergency care amid threats to infrastructure and personnel safety. Existing literature focuses on individual aspects like mass casualty protocols or medical neutrality, with limited analysis of operating acute services directly under fire. OBJECTIVES: To describe the experience of a hospital situated meters from hostilities and analyze strategies implemented for triage, expanding surge capacity, and maintaining continuity of care during attacks with limited medical staff availability due to hazardous conditions. A focus will be placed on assessing how the hospital functioned and adapted care delivery models in the event of staffing limitations preventing all teams from arriving on site. METHODS: A retrospective case study was conducted of patient records from Barzilai University Medical Center at Ashkelon (BUMCA) Medical Center in Israel within the first 24 h after escalated conflict began on October 7, 2023. Data on 232 admissions were analyzed regarding demographics, treatment protocols, time to disposition, and mortality. Missile alert data correlated patient surges to attacks. Statistical and geospatial analyses were performed. RESULTS: Patients predominantly male soldiers exhibited blast/multisystem trauma. Patient surges at the hospital were found to be correlated with the detection of incoming missile attacks from Gaza within 60 min of launch. While 131 (56%) patients were discharged and 55 (24%) transferred within 24 h, probabilities of survival declined over time reflecting injury severity limitations. 31 deaths occurred from severe presentation. CONCLUSION: Insights gleaned provide a compelling case study on managing mass casualties at the true frontlines. By disseminating BUMCA's trauma response experience, strategies can strengthen frontline hospital protocols optimizing emergency care delivery during hazardous armed conflicts through dynamic surge capacity expansion, early intervention prioritization, and infrastructure/personnel protection measures informed by risks.

Secondary Ambulance Transfers During the Mass-Casualty Terrorist Attack in Israel on October 7, 2023.

On October 7, 2023, Israel experienced the worst terror attack in its history - 1,200 people were killed, 239 people were taken hostage, and 1,455 people were wounded. This mass-casualty event (MCE) was more specifically a mega terrorist attack. Due to the overwhelming number of victims who arrived at the two closest hospitals, it became necessary to implement secondary transfers to centers in other areas of the country. Historically, secondary transfer has been implemented in MCEs but usually for the transfer of critical patients from a Level 2 or Level 3 Trauma Center to a Level 1 Center. Magen David Adom (MDA), Israel's National Emergency Pre-Hospital Medical Organization, is designated by the Health Ministry as the incident command at any MCE. On October 7, in addition to the primary transport of victims by ambulance to hospitals throughout Israel, they secondarily transported patients from the two closest hospitals - the Soroka Medical Center (SMC; Level 1 Trauma Center) in Beersheba and the Barzilai Medical Center (BMC; Level 2 Trauma Center) in Ashkelon. Secondary transport began five hours after the event started and continued for approximately 12 hours. During this time, the terrorist infiltration was still on-going. Soroka received 650 victims and secondarily transferred 26, including five in Advanced Life Support (ALS) ambulances. Barzilai received 372 and secondarily transferred 38. These coordinated secondary transfers helped relieve the overwhelmed primary hospitals and are an essential component of any MCE strategy.

Interorganizational Knowledge Transfer in Mass Gatherings: Exploring the Health and Safety Stakeholders' Perceptions Participating in the Athens Marathon.

INTRODUCTION: Mass gatherings (MGs) usually represent significant challenges for the public health and safety sector of the host cities. Organizing a safe and successful mass event highly depends on the effective collaboration among different public and private organizations. It is necessary to establish successful coordination to ensure that all the key stakeholders understand their respective roles and responsibilities. The inconsistency between the variety of participating agencies because of their different culture can result in delays in decision making. Interorganizational knowledge transfer can improve the success of the event; however, knowledge transfer among professionals and agencies in MGs is not well-documented. OBJECTIVE: This study used the 2018 Athens Marathon as the empirical setting to examine how interorganizational knowledge transfer was perceived among the multiple public health and safety professionals during the planning stage of the event. METHODS: Data comprised 18 semi-structured, in-depth interviews with key informants, direct observations of meetings, and documentary analysis. Open coding and thematic analysis were used to analyze the data. RESULTS: Findings indicated that sharing the acquired knowledge was a necessary and challenging step to create an enabling collaborative environment among interacting organizations. Experiential learning was identified as a significant factor, which helped promote joint understanding and partnership work. Informal interpersonal exchanges and formal knowledge transfer activities facilitated knowledge sharing across organizational boundaries, helping to break down silos. CONCLUSION: Interorganizational knowledge transfer is a necessary step to achieve joint understanding and create an environment where interaction among agencies can be more effective. The study findings can be beneficial for organizers of marathons and other mass sporting events to support valuable interorganizational collaboration and conduct a safe event.

Comparative Analysis of META and SALT Disaster Triage in an Adult Trauma Population: A Retrospective Observational Study.

BACKGROUND: Medical professionals can use mass-casualty triage systems to assist them in prioritizing patients from mass-casualty incidents (MCIs). Correct triaging of victims will increase their chances of survival. Determining the triage system that has the best performance has proven to be a difficult question to answer. The Advanced Prehospital Triage Model (Modelo Extrahospitalario de Triaje Avanzado; META) and Sort, Assess, Lifesaving Interventions, Treatment/Transport (SALT) algorithms are the most recent triage techniques to be published. The present study aimed to evaluate the META and SALT algorithms' performance and statistical agreement with various standards. The secondary objective was to determine whether these two MCI triage systems predicted patient outcomes, such as mortality, length-of-stay, and intensive care unit (ICU) admission. METHODS: This retrospective study used patient data from the trauma registry of an American College of Surgeons Level 1 trauma center, from January 1, 2018 through December 31, 2020. The sensitivity, specificity, and statistical agreement of the META and SALT triage systems to various standards (Revised Trauma Score [RTS]/Sort Triage, Injury Severity Score [ISS], and Lerner criteria) when applied using trauma patients. Statistical analysis was used to assess the relationship between each triage category and the secondary outcomes. RESULTS: A total of 3,097 cases were included in the study. Using Sort triage as the standard, SALT and META showed much higher sensitivity and specificity in the Immediate category than for Delayed (Immediate sensitivity META 91.5%, SALT 94.9%; specificity 60.8%, 72.7% versus Delayed sensitivity 28.9%, 1.3%; specificity 42.4%, 28.9%). With the Lerner criteria, in the Immediate category, META had higher sensitivity (77.1%, SALT 68.6%) but lower specificity (61.1%) than SALT (71.8%). For the Delayed category, SALT showed higher sensitivity (META 61.4%, SALT 72.2%), but lower specificity (META 75.1%, SALT 67.2%). Both systems showed a positive, though modest, correlation with ISS. For SALT and META, triaged Immediate patients tended to have higher mortality and longer ICU and hospital lengths-of-stay. CONCLUSION: Both META and SALT triage appear to be more accurate with Immediate category patients, as opposed to Delayed category patients. With both systems, patients triaged as Immediate have higher mortality and longer lengths-of-stay when compared to Delayed patients. Further research can help refine MCI triage systems and improve accuracy.

[Management of a mass casualty incident according to the recommendations of the Federal Office of Civil Protection and Disaster Assistance and the principles of the Terror and Disaster Surgical Care Concept in a regional trauma center]. / Management eines Massenanfalls von Verletzten nach den Empfehlungen des Bundesamtes für Bevölkerungsschutz und Katastrophenhilfe und den Prinzipien des Terror-and-Disaster-Surgical-Care-Konzepts in einem regionalen Traumazentrum.

Dealing with a mass casualty incident presents many challenges in the clinical and preclinical situation. There are various systems and structures to address this problem. In the present work, the management of the train accident near Garmisch-Partenkirchen on 3 June 2022 is evaluated with the aid of the recommendations of the Federal Office for Civil Protection and Disaster Relief for hospital alarm and deployment planning as well as the recommendations from the terror and disaster surgical care training of the German Academy of Trauma Surgery and the findings are presented from the perspective of a regional trauma center. It also discusses which key factors in the present case have proved to be successful and in which areas there is still a need for improvement.

The effect of multiple triage points on the outcomes (time and accuracy) of hospital triage during mass casualty incidents.

INTRODUCTION: During mass casualty incidents (MCIs), the accuracy and timing of the triage of patients by the emergency department (ED) triage officers are essential. The primary triage is performed at the event's location by paramedics and intends a quick evaluation of the victims. Secondary triage may be used when the transfer of the victim is delayed. In this study, we aimed to investigate the effectiveness of two-point triage in a simulated environment of an MCI in the hospital setting. MATERIALS AND METHODS: In this case-control study, we used an online test module to assess single triage points (Group 1, n = 41) and two triage points (Group 2, n = 40). 60 vignettes for Group 1 and 55 vignettes (5 deceased cases removed) for Group 2 were used. The assessment utilized clinical MCI scenarios in a scheduled online meeting by using the Simple Triage and Rapid Treatment (START) system. Triage time and accuracy of the triage, along with the experience, and previous training of the participants, were assessed. RESULTS: A total of 81 triage officers participated in this study. The participants were divided into two independent groups homogenously according to their profession and experience. Groups were comparable primarily without any statistically significant difference in terms of the profession (p = 0.101), sex (p = 0.923), and MCI experience (p = 0.785). The difference between the two groups was not significant with regard to having received practical or theoretical triage training (p = 0.099). The mean time of a single vignette triage was 19.2 (SD 6.5) seconds and mean percentage of correct triage score was 65.0 (SD 12.6). The participants had a statistically significantly better performance in the single-point triage group regarding the median triage time (p < 0.001) and median percentages of under triage (p = 0.001), but a worse median percentage of over triage (p < 0.001). However, there was no significant difference between the two groups in terms of the percentage of accurate triage. Emergency residents performed better in accuracy and triage time than their non-physician colleagues (p = 0.019). CONCLUSIONS: Two-point triage does not demonstrate better outcomes in terms of accuracy and timing. Triage officers should be trained frequently with the preferred training methodology to prevent improper triage accuracy and timing. Well-defined medical disaster planning should include frequent training of the triage officers with case scenarios.

Mass Casualty Incident Preparedness for Airport Emergencies: Report From an Aeroplane Crash Simulation at Guglielmo Marconi Airport, Bologna (Italy).

BACKGROUND: Airport emergencies are rare but potentially catastrophic; therefore, system preparedness is crucial. Airport emergency plans include the organization of emergency drills on a regular basis, including full-scale exercises, to train and test the entire rescue organization. OBJECTIVE: This report describes a full-scale simulation at Bologna International Airport, Italy, in October 2022, involving local EMS resources. METHODS: A full-scale aeroplane crash was simulated on the airport ground, activating the Airport emergency plan, and requiring the intervention of supplementary resources (ambulances, medical cars, and other emergency vehicles). RESULTS: Twenty-seven simulated patients were evaluated by EMS: START triage assessment was correct for 81.48% of patients; 11.11% were over-triaged and 7.41% were under-triaged. All patients were transported to the hospitals of the area. The simulation ended 2 hours and 28 minutes after the initial alarm. CONCLUSION: The response time proved a good response. Triage accuracy was correct in more than 80% of simulated patients. The availability of a trauma centre within 6 kilometres allowed the transportation of a quota of patients directly from the event, without affecting transportation times. Areas for improvement were identified in the communication within the different agencies and in moving ambulances within the airport runway without airport personnel guidance.

Identification using Hand Remnants at the Mass Casualty Site: Forensic Perspective.

Identification is one of the most important aspects of mass disasters. Stature estimation is an essential parameter for identification and is widely used in forensic anthropology, where DNA facility is limited. A hand is most studied part of the upper limb; however, data are scarce concerning particular geographical populations. This study is an effort to provide tangible data for such forensic investigations. It was a prospective, cross-sectional study on 500 medicolegal death cases brought for post-mortem examination. It aimed to estimate stature in the Northwest population using hand and finger measurements of dead persons by mathematical models. A total of seven parameters in hand were used to generate linear and multiple regression equations, correlation coefficients and finger indexes for stature estimation and sex differentiation. The correlation coefficient between stature and all the hand measurements were significant except for the index and middle finger on both sides in females. Bilateral differences were insignificant for hand length and breath, except for the middle finger length in both sexes and length of thumb in females. Multiple regression equations for stature estimation were better than linear regression equations for stature estimation. SEE ranged from 4.31 to 6.26 in males and 4.11 to 5.25 in females. For identification, hand length is the best individual parameter among other hand measurements. The measurement accuracy and practical aspects can be enhanced if we consider cadaveric participants. The multiple regression model approach can give a fair estimate of the stature of the deceased.

The Impact of Exposure to Previous Disasters on Hospital Disaster Surge Capacity Preparedness in Finland: Hospital disaster surge capacity preparedness.

OBJECTIVE: As disasters are rare and high-impact events, it is important that the learnings from disasters are maximized. The aim of this study was to explore the effect of exposure to a past disaster or mass casualty incident (MCI) on local hospital surge capacity planning. METHODS: The current hospital preparedness plans of hospitals receiving surgical emergency patients in Finland were collected (n = 28) and analyzed using the World Health Organization (WHO) hospital emergency checklist tool. The surge capacity score was compared between the hospitals that had been exposed to a disaster or MCI with those who had not. RESULTS: The overall median score of all key components on the WHO checklist was 76% (range 24%). The median surge capacity score was 65% (range 39%). There was no statistical difference between the surge capacity score of the hospitals with history of a disaster or MCI compared to those without (65% for both, P = 0.735). CONCLUSION: Exposure to a past disaster or MCI did not appear to be associated with an increased local hospital disaster surge capacity score. The study suggests that disaster planning should include structured post-action processes for enabling meaningful improvement after an experienced disaster or MCI.

Trends and Characteristics of Terrorist Attacks Against Nightclub Venues Over 5 Decades.

INTRODUCTION: Nightclubs are entertainment and hospitality venues historically vulnerable to terrorist attacks. This study identified and characterized terrorist attacks targeting nightclubs and discotheques documented in the Global Terrorism Database (GTD) over a 50-y period. METHODS: A search of the Global Terrorism Database (GTD) was conducted from 1970 to 2019. Precoded variables for target type "business" and target subtype "entertainment/cultural/stadium/casino" were used to identify attacks potentially involving nightclubs. Nightclub venues were specifically identified using the search terms "club," "nightclub," and "discotheque." Two authors manually reviewed each entry to confirm the appropriateness for inclusion. Descriptive statistics were performed using R (3.6.1). RESULTS: A total of 114 terrorist attacks targeting nightclub venues were identified from January 1, 1970, through December 31, 2019. Seventy-four (64.9%) attacks involved nightclubs, while forty (35.1%) attacks involved discotheques. A bombing or explosion was involved in 84 (73.7%) attacks, followed by armed assault in 14 (12.3%) attacks. The highest number of attacks occurred in Western Europe and Sub-Saharan Africa. In total, 284 persons died, and 1175 persons were wounded in attacks against nightclub venues. CONCLUSIONS: While terrorist attacks against nightclub venues are infrequent, the risk for mass casualties and injuries can be significant, mainly when explosives and armed assaults are used.

Factors Associated with the Number of Injured and Fatalities in Motor Vehicle Intentional Mass-Casualty Incidents: A Timely Aid for Scaling the Emergency Response.

INTRODUCTION: Intentional mass-casualty incidents (IMCIs) involving motor vehicles (MVs) as weapons represent a growing trend in Western countries. This method has resulted in the highest casualty rates per incident within the field of IMCIs. Consequently, there is an urgent requirement for a timely and accurate casualty estimation in MV-induced IMCIs to scale and adjust the necessary health care resources. STUDY OBJECTIVE: The objective of this study is to identify the factors associated with the number of casualties during the initial phase of MV-IMCIs. METHODS: This is a retrospective, observational, analytical study on MV-IMCIs world-wide, from 2000-2021. Data were obtained from three different sources: Targeted Automobile Ramming Mass-Casualty Attacks (TARMAC) Attack Database, Global Terrorism Database (GTD), and the vehicle-ramming attack page from the Wikipedia website. Jacobs' formula was used to estimate the population density in the vehicle's route. The primary outcome variables were the total number of casualties (injured and fatalities). Associations between variables were analyzed using Spearman's correlation coefficient and simple linear regression. RESULTS: Forty-six MV-IMCIs resulted in 1,636 casualties (1,430 injured and 206 fatalities), most of them caused by cars. The most frequent driving pattern was accelerating whilst approaching the target, with an average speed range between four to 130km/h and a distance traveled between ten to 2,260 meters. The people estimated in the MV-IMCI scenes ranged from 36-245,717. A significant positive association was found of the number affected with the estimated crowd in the scene (R2: 0.64; 95% CI, 0.61-0.67; P <.001) and the average vehicle speed (R2: 0.42; 95% CI, 0.40-0.44; P = .004). CONCLUSION: The estimated number of people in the affected area and vehicle's average speed are the most significant variables associated with the number of casualties in MV-IMCIs, helping to enable a timely estimation of the casualties.

Global Neurosurgery Advances From Trenches to Bedside: Lessons From Neurosurgical Care in War, Humanitarian Assistance, and Disaster Response.

INTRODUCTION: War has influenced the evolution of global neurosurgery throughout the past century. Armed conflict and mass casualty disasters (MCDs), including Humanitarian Assistance Disaster Relief missions, require military surgeons to innovate to meet extreme demands. However, the military medical apparatus is seldom integrated into the civilian health care sector. Neurosurgeons serving in the military have provided a pragmatic template for global neurosurgeons to emulate in humanitarian disaster responses. In this paper, we explore how wars and MCD have influenced innovations of growing interest in the resource-limited settings of global neurosurgery. METHODS: We performed a narrative review of the literature examining the influence of wars and MCD on contemporary global neurosurgery practices. RESULTS: Wartime innovations that influenced global neurosurgery include the development of triage systems and modernization with airlifts, the implementation of ambulance corps, early operation on cranial injuries in hospital camps near the battlefield, the use of combat body armor, and the rise of damage control neurosurgery. In addition to promoting task-shifting and task-sharing, workforce shortages during wars and disasters contributed to the establishment of the physician assistant/physician associate profession in the USA. Low- and middle-income countries (LMICs) face similar challenges in developing trauma systems and obtaining advanced technology, including neurosurgical equipment like battery-powered computed tomography scanners. These challenges-ubiquitous in low-resource settings-have underpinned innovations in triage and wound care, rapid evacuation to tertiary care centers, and minimizing infection risk. CONCLUSION: War and MCDs have catalyzed significant advancements in neurosurgical care both in the pre-hospital and inpatient settings. Most of these innovations originated in the military and subsequently spread to the civilian sector as military neurosurgeons and reservist civilian neurosurgeons returned from the battlefront or other low-resource locations. Military neurosurgeons have utilized their experience in low-resource settings to make volunteer global neurosurgery efforts in LMICs successful. LMICs have, by necessity, responded to challenges arising from resource shortages by developing innovative, context-specific care paradigms and technologies.

[Inpatient surgical treatment in mass casualty situations and disasters-Principles, targets, concepts, preparation]. / Stationäre chirurgische Versorgung in Großschadenslagen und Katastrophen ­ Grundlagen, Ziele, Konzepte, Vorbereitung.

BACKGROUND: The war in Ukraine and the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) pandemic have moved the resilience of the healthcare system in Germany into the focus of a broad discussion. The preparation for such a damage situation is characterized by the relationship between the available treatment capacity and needs which go far beyond the norm. The aim of a resilient healthcare system must be to adequately react to such exceptional situations. Particularly in acute disaster and mass casualty situations, medical standards and an individualized surgical treatment must be maintained for as long as possible. MATERIAL, METHOD AND OBJECTIVE: The aim of this article is to elucidate the current terminology on medical treatment of patients in disasters from a surgical perspective, to further develop available concepts and possible concepts of crisis management based on three schematically presented scenarios. Furthermore, the general reaction possibilities for mobilization of treatment capacities are described. RESULTS: In order to uniformly collate the quality of medical treatment in a damage situation, it is meaningful to include the stages of individualized treatment, compensated crisis care and decompensated crisis care. Within the framework of a mass casualty situation or a disaster, traumatological and surgical patients are predominant and the aim must be to maintain or restore the stage of a compensated crisis management. Depending on the extent of the damage situation, this can only be realized in a timely manner independent of state boundaries and by a superordinate central management structure. For a comprehensive provision of surgical treatment capacities, the depiction of a continuous overview of the situation with current resources and structural data of the hospitals in the affected region is necessary. CONCLUSION: The aim of all efforts and preparations must therefore be to durably strengthen hospitals and to train and develop this with respect to coping with a damage situation in disaster medicine. In this respect it is important to establish a consensus on terminology, the type of treatment and the tactical strategic principles of surgical treatment to cope with a disaster or damage situation.

Optimizing Mass Casualty Triage: Using Discrete Event Simulation to Minimize Time to Resuscitation.

BACKGROUND: Urban areas in the US are increasingly focused on mass casualty incident (MCI) response. We simulated prehospital triage scenarios and hypothesized that using hospital-based blood product inventories for on-scene triage decisions would minimize time to treatment. STUDY DESIGN: Discrete event simulations modeled MCI casualty injury and patient flow after a simulated blast event in Boston, MA. Casualties were divided into moderate (Injury Severity Score 9 to 15) and severe (Injury Severity Score >15) based on injury patterns. Blood product inventories were collected from all hospitals (n = 6). The primary endpoint was the proportion of casualties managed with 1:1:1 balanced resuscitation in a target timeframe (moderate, 3.5 U red blood cells in 6 hours; severe, 10 U red blood cells in 1 hour). Three triage scenarios were compared, including unimpeded casualty movement to proximate hospitals (Nearest), equal distribution among hospitals (Equal), and blood product inventory-based triage (Supply-Guided). RESULTS: Simulated MCIs generated a mean ± SD of 302 ± 7 casualties, including 57 ± 2 moderate and 15 ± 2 severe casualties. Nearest triage resulted in significantly fewer overall casualties treated in the target time (55% vs Equal 86% vs Supply-Guided 91%, p < 0.001). These differences were principally due to fewer moderate casualties treated, but there was no difference among strategies for severe casualties. CONCLUSIONS: In this simulation study comparing different triage strategies, including one based on actual blood product inventories, nearest hospital triage was inferior to equal distribution or a Supply-Guided strategy. Disaster response leaders in US urban areas should consider modeling different MCI scenarios and casualty numbers to determine optimal triage strategies for their area given hospital numbers and blood product availability.
