The medical response to multisite terrorist attacks in Paris

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.

Differences in predictive factors for post-traumatic stress disorder encompassing partial PTSD and full PTSD: a cross-sectional study among individuals exposed to the November 13, 2015 Paris attacks

Background

When faced with a surge of physically injured individuals, especially following a traumatic event like an attack, frontline practitioners prioritize early triage. Detecting potential psychological injuries soon after such events remains challenging. Some individuals might develop post-traumatic stress disorder (PTSD) according to DSM-V criteria. Others may exhibit PTSD symptoms without meeting full diagnostic criteria, termed partial or sub-syndromal PTSD, a less-explored area in literature. This study aims to identify predictive factors for both full and partial PTSD.

Method

In a cohort of victims of the 2015 Paris attacks, multinomial logistic regressions explored predictive factors for partial or full PTSD status 8 to 18 months post-attacks. Analyses considered pre, peri, and posttraumatic factors chosen from literature review and univariate analysis within each group.

Results

Within the cohort, 50 individuals showed no signs of PTSD, 35 experienced partial PTSD, and 30 presented with full PTSD. After logistic regression, risk factors associated with full PTSD included a history of trauma (OR = 1.30, CI [1.02-1.66], p < 0.05), the intensity of peri-traumatic physical reactions (OR = 1.22, CI [1.09-1.36], p < 0.001), the difficulties in suppressing intrusive thoughts (OR = 1.11, CI [1.02-1.21], p < 0.013). Only the intensity of peri-traumatic physical reactions emerged as a risk factor for partial PTSD (OR = 1.13, [CI 1.02-1.24], p < 0.001).

Discussion

This study revealed that a history of trauma, the intensity of peri-traumatic physical reactions (e.g., tachycardia, trembling, flushes, numbness.), and the difficulties in suppressing intrusive thoughts constitute risk factors for the development of full PTSD. Moreover, the study identified that only the intensity of peri-traumatic physical reactions emerged as a risk factor for partial PTSD. These findings seem to underscore the significance of peri-traumatic experiences in influencing the development of post-traumatic stress symptoms.

Conclusion

This study emphasizes the significance of examining peri-traumatic reactions in PTSD development, suggesting its potential as a straightforward screening tool for post-traumatic stress disorder. It also underscores the influence of prior traumatic experiences, before de novo traumatization, in shaping vulnerability to PTSD and illuminates the crucial role of compromised control of intrusive thoughts that could perpetuate PTSD.

Triage in major incidents: development and external validation of novel machine learning-derived primary and secondary triage tools

BACKGROUND

Major incidents (MIs) are an important cause of death and disability. Triage tools are crucial to identifying priority 1 (P1) patients-those needing time-critical, life-saving interventions. Existing expert opinion-derived tools have limited evidence supporting their use. This study employs machine learning (ML) to develop and validate models for novel primary and secondary triage tools.

METHODS

Adults (16+ years) from the UK Trauma Audit and Research Network (TARN) registry (January 2008-December 2017) served as surrogates for MI victims, with P1 patients identified using predefined criteria. The TARN database was split chronologically into model training and testing (70:30) datasets. Input variables included physiological parameters, age, mechanism and anatomical location of injury. Random forest, extreme gradient boosted tree, logistic regression and decision tree models were trained to predict P1 status, and compared with existing tools (Battlefield Casualty Drills (BCD) Triage Sieve, CareFlight, Modified Physiological Triage Tool, MPTT-24, MSTART, National Ambulance Resilience Unit Triage Sieve and RAMP). Primary and secondary candidate models were selected; the latter was externally validated on patients from the UK military's Joint Theatre Trauma Registry (JTTR).

RESULTS

Models were internally tested in 57 979 TARN patients. The best existing tool was the BCD Triage Sieve (sensitivity 68.2%, area under the receiver operating curve (AUC) 0.688). Inability to breathe spontaneously, presence of chest injury and mental status were most predictive of P1 status. A decision tree model including these three variables exhibited the best test characteristics (sensitivity 73.0%, AUC 0.782), forming the candidate primary tool. The proposed secondary tool (sensitivity 77.9%, AUC 0.817), applicable via a portable device, includes a fourth variable (injury mechanism). This performed favourably on external validation (sensitivity of 97.6%, AUC 0.778) in 5956 JTTR patients.

CONCLUSION

Novel triage tools developed using ML outperform existing tools in a nationally representative trauma population. The proposed primary tool requires external validation prior to consideration for practical use. The secondary tool demonstrates good external validity and may be used to support decision-making by healthcare workers responding to MIs.

A day in the life: psychological impact on emergency responders during the 22 March 2016 terrorist attacks

Introduction

Terrorist attacks can cause severe long-term mental health issues that need treatment. However, in the case of emergency responders, research is often vague on the type of stressors that emergency responders encounter. For example, in addition to the threat that they work under, studies have shown that ill-preparation adds to the stress experienced by emergency responders. However, few studies have looked into the experience of emergency responders. In this study, we looked at the experience of emergency responders during the 22 March 2016 terrorist attacks in Belgium.

Methods

We used a qualitative design, in which we interviewed different types of emergency responders. Police officers, nurses, soldiers, firefighters, and Red Cross volunteers were included. Interviews were coded by two researchers and analyzed using a thematic approach.

Results

Four large themes were developed: constant threat and chaos, frustrations with lack of preparedness and training, ethical decisions, and debriefings. In addition, although emergency responders encountered constant threat, they often felt that they were ill-prepared for such attacks. One specific example was their lack of training in tourniquet usage. Furthermore, in a disaster setting, the emergency responders had to make life-and-death decisions for which they were not always prepared. Finally, debriefings were conducted in the aftermath of the attacks. Whereas most were perceived as positive, the debriefings among police officers were viewed as insufficient.

Conclusions

Emergency responding to terrorist attacks has many different dimensions of events that can cause stress. Our study revealed that preparation is key, not only in terms of material but also in terms of ethics and debriefings.

Evaluation of prehospital preparedness for major incidents on a national level, with focus on mass casualty incidents

PURPOSE

To investigate prehospital preparedness work for Mass Casualty Incidents (MCI) and Major Incidents (MI) in Norway.

METHOD

A national cross-sectional descriptive study of Norway's prehospital MI preparedness through a web-based survey. A representative selection of Rescue and Emergency Services were included, excluding Non-Governmental Organisations and military. The survey consisted of 59 questions focused on organisation, planning, education/training, exercises and evaluation.

RESULTS

Totally, 151/157 (96%) respondents answered the survey. The results showed variance regarding contingency planning for MCI/MI, revisions of the plans, use of national triage guidelines, knowledge requirements, as well as haemostatic and tactical first aid skills training. Participation in interdisciplinary on-going life-threatening violence (PLIVO) exercises was high among Ambulance, Police and Fire/Rescue Emergency Services. Simulations of terrorist attacks or disasters with multiple injured the last five years were reported by 21/151 (14%) on a regional level and 74/151 (48%) on a local level. Evaluation routines after MCI/MI events were reported by half of the respondents (75/151) and 70/149 (47%) described a dedicated function to perform such evaluation.

CONCLUSION

The study indicates considerable variance and gaps among Prehospital Rescue and Emergency Services in Norway regarding MCI/MI preparedness work, calling for national benchmarks, minimum requirements, follow-up routines of the organisations and future reassessments. Implementation of mandatory PLIVO exercises seems to have contributed to interdisciplinary exercises between Fire/Rescue, Police and Ambulance Emergency Service. Repeated standardised surveys can be a useful tool to assess and follow-up the MI preparedness work among Prehospital Rescue and Emergency Services at a national, regional and local level.

Time to Reconsider Analgesia in Mass Casualty Incidents

The provision of analgesia in mass casualty incidents has traditionally been viewed as low-priority and reserved for later stages of care. Poor pain management is commonplace in trauma victims, and inadequate acute pain management can hinder evacuation efforts and may lead to the development of chronic pain and posttraumatic stress disorder. New, safe, and simple methods for administering quality analgesia have proven to be safe and effective in the prehospital setting and, as such, could easily be implemented into mass casualty incident protocols and allow for analgesia at earlier stages in such incidents, thereby improving patient care.

Nord-Ost: Russia's Medical Failure in the 2002 Crisis

The 2002 hostage crisis at a Moscow theater transfixed the attention of the world. While the initial assault, led by Spetsnaz commandos, successfully secured the building, the Russian security force's utter failure at coordinating with medical services led to the preventable deaths of over 100 hostages.

Factors affecting the preparedness of Helicopter Emergency Medical Services (HEMS) in disasters: a systematic review

BACKGROUND

One of the most significant advantages of Helicopter Emergency Medical Service (HEMS) in disaster relief efforts is their ability to reach inaccessible or remote areas quickly. This is especially important in the aftermath of natural disasters such as earthquakes, floods, or hurricanes, where roads may be blocked or damaged, and conventional ground transportation may not be available. There are many factors can affect the performance of Helicopter Emergency Medical Service (HEMS) in disasters. This study aims to investigate the factors affecting the Helicopter Emergency Medical Service (HEMS) in disasters.

METHODS

The systematic search in Cochran Library, PubMed, Scopus, Science Direct, Web of Science, ProQuest, and Google Scholar databases between the first of January in 1975 and the thirty-first of May in 2023. The articles were selected based on the keywords of the authors. At last, the criteria were extracted from the selected ones.

RESULTS

The primary search included 839 articles. After studying their title, abstract, and full context, only nine articles, including two qualitative and seven quantitative ones, were chosen for analysis. After analysis and extracting data from the final studies, the preparation factors were categorized into 6 general classes of human resources: training and practicing, management, instructions and standards, equipment, and structure. Among these, the role of training is highlighted by holding practice and maneuvers to improve and prepare the personnel and manage disasters and incidents.

CONCLUSION

The results obtained from this systematic review provide a total view of the factors affecting the preparation of the air ambulance during disasters and incidents. It is recommended that senior managers and policy makers use the findings of the present study to identify the factors which affect preparedness of HEMS in disasters and take the necessary measures to eliminate to obstacles.

The Field's mass shooting: emergency medical services response

BACKGROUND

Major incidents (MI) happen infrequently in Scandinavia and mass shootings are even less frequently occurring. Case reports and research are called for, as literature is scarce. On 3rd July 2022, a mass shooting took place at the shopping mall Field's in Copenhagen, Denmark. Three people were killed and seven injured by a gunman, firing a rifle inside the mall. A further 21 people suffered minor injuries during the evacuation of the mall. In this case report, we describe the emergency medical services (EMS) incident response and evaluate the EMS´ adherence to the MI management guidelines to identify possible areas of improvement.

CASE PRESENTATION

Forty-eight EMS units including five Tactical Emergency Medical Service teams were dispatched to the incident. Four critically injured patients were taken to two trauma hospitals. The deceased patients were declared dead at the scene and remained there for the sake of the investigation. A total of 24 patients with less severe and minor injuries were treated at four different hospitals in connection with the attack. The ambulance resources were inherently limited in the initial phase of the MI, mandating improvisation in medical incident command. Though challenged, Command and Control, Safety, Communication, Assessment, Triage, Treatment, Transport (CSCATTT) principles were followed.

CONCLUSIONS

The EMS response generally adhered to national guidelines for MI. The activation of EMS and the hospital preparedness program was relevant. Important findings were communication shortcomings; inherent lack of readily available ambulance resources in the initial critical phase; uncertainty regarding the number of perpetrators; uncertainty regarding number of casualties and social media rumors that unnecessarily hampered and prolonged the response. The incident command had to use non-standard measures to mitigate potential challenges.

A Gray Future: The Role of the Anesthesiologist in Hybrid Warfare

During the last few decades, the increasing use of asymmetric and multimodal tactics by terrorists has led anesthesiologists worldwide to analyze and discuss their role in mass casualty scenarios in more depth. Now anesthesiologists must address the new situation of hybrid threats and hybrid warfare. This will have a direct impact on anesthesiology and intensive care, and in the end, the health and well-being of critical patients of all ages. To be able to respond to a hybrid threat efficiently and effectively, it is imperative that anesthesiologists play an early and integral role in mitigation and response planning.

Communication failure in the prehospital response to major terrorist attacks: lessons learned and future directions

INTRODUCTION

Communication is key in efficient disaster management. However, in many major incidents, prehospital communication failure led to insufficient upscaling, safety concerns for the emergency responders, logistical problems and inefficient disaster management.

METHODS

A review of medical reports and news articles of mass-casualty terrorist attacks was performed using PubMed-archived and (non-)governmental reports. The terrorist attacks in Tokyo 1995, Oklahoma 1995, Omagh 1998, New York 2001, Myyr-manni 2002, Istanbul 2003, Madrid 2004, London 2005, Oslo/Utøya 2011, Boston 2013, Paris 2015, Berlin 2016, Brussels 2016, Wuerzburg 2016, Manchester 2017, London 2017 were included.

RESULTS

In all mass-casualty terrorist attacks, communication failure was reported. Some failures had significant impact on casualty numbers. Outdated communication equipment, overwhelmed communication services, failure due to damaged infrastructure by the terrorist attack itself, and lack of training were the major issues. Communication failures were most commonly observed in both attacks between 1995-2009 and 2011-2017.

DISCUSSION

Communication failure was reported in all mass-casualty terrorist incidents. In several cases, communication between the different responding actors was poor or non-existing. Malfunctioning of (outdated) telecommunication services, inadequate training in the use of communication devices, unfortunate damage of telecommunication network infrastructure were also worrisome.

CONCLUSION

Despite reports of lessons learned in previous EMS responses, communication failures were still reported in most recent terrorist attacks. Governments should provide sufficient resources to equip hospitals, emergency departments, and ambulance services with (back-up) communication systems and invest in training. A European registration system is warranted. We provide proposals for improvement.

The positive impact of COVID-19 on critical care: from unprecedented challenges to transformative changes, from the perspective of young intensivists

Over the past 2 years, SARS-CoV-2 infection has resulted in numerous hospitalizations and deaths worldwide. As young intensivists, we have been at the forefront of the fight against the COVID-19 pandemic and it has been an intense learning experience affecting all aspects of our specialty. Critical care was put forward as a priority and managed to adapt to the influx of patients and the growing demand for beds, financial and material resources, thereby highlighting its flexibility and central role in the healthcare system. Intensivists assumed an essential and unprecedented role in public life, which was important when claiming for indispensable material and human investments. Physicians and researchers around the world worked hand-in-hand to advance research and better manage this disease by integrating a rapidly growing body of evidence into guidelines. Our daily ethical practices and communication with families were challenged by the massive influx of patients and restricted visitation policies, forcing us to improve our collaboration with other specialties and innovate with new communication channels. However, the picture was not all bright, and some of these achievements are already fading over time despite the ongoing pandemic and hospital crisis. In addition, the pandemic has demonstrated the need to improve the working conditions and well-being of critical care workers to cope with the current shortage of human resources. Despite the gloomy atmosphere, we remain optimistic. In this ten-key points review, we outline our vision on how to capitalize on the lasting impact of the pandemic to face future challenges and foster transformative changes of critical care for the better.

Terrorist Attacks against Sports Venues: Emerging Trends and Characteristics Spanning 50 Years

INTRODUCTION

Sports venues foster community and support local economies. Due to their capacity to host hundreds to thousands of spectators, sports venues are vulnerable to becoming targets of terrorism. Types of venues targeted, regional trends, and methods of attack employed world-wide have not been well-described.

METHODS

A search of the Global Terrorism Database (GTD) was conducted from 1970 through the end of 2019. Pre-coded variables for target type "business" and target subtype "entertainment/cultural/stadium/casino" were used to identify attacks involving venues where sports events might be viewed by spectators as part of an audience. Sports venues were specifically identified using the search terms "sport," "stadium," "arena," and "ring," as well as mention of any specific sport. Two authors then manually reviewed each entry for specific information to confirm appropriateness for inclusion, selecting preferentially for attacks against venues where watching a sports event was the primary focus for the majority of the attendees. Descriptive statistics were performed using R (3.6.1).

RESULTS

Seventy-four (74) terrorist attacks targeting sports venues were identified from January 1, 1970 through December 31, 2019. Thirty-three (33) attacks, or 44.6% of attacks, involved soccer stadiums or soccer venues, while 33.8% of attacks (25 attacks) involved unspecified sports venues. A bombing or explosion was the most frequent method of attack employed, comprising 87.8% of attacks. The highest number of attacks occurred in the Middle East & North Africa. In total, 213 persons died and 699 more were wounded in attacks against sports venues.

CONCLUSION

Although terrorist attacks against sports venues are uncommon, they carry the risk of mass casualties, especially when explosives are used. A greater understanding of the threat posed by terrorist attacks against sports venues can aid emergency preparedness planning and future medical responses.

When disaster strikes: staff recall and the use of staff recall systems during mass patient influx at Norwegian emergency primary health care centers - a cross-sectional study

BACKGROUND

In Norway, planning for disasters has been specifically emphasized since the incidents on July 22^nd, 2011. Every municipality is now legislated to have a contingency plan that includes plans for staff recall during situations with mass influx of patients. Whether the primary health care services in Norway are prepared for mass influx of patients remains unclear.

AIMS OF THE STUDY

The aims of this study were (1) to assess the experiences of head doctors at emergency primary health care centers (EPHCC) in Norway with mass influx of patients, (2) to explore mass influx and staff recall procedures in use, (3) to assess head doctors' experiences with staff recall systems, and (4) to assess their perspective on automatized staff recall systems. We also wanted to assess whether there were differences between small and large EPHCCs regarding whether they had plans in place.

METHODS

The study had a cross-sectional, multicenter design, using a self-developed questionnaire. The questionnaire was developed utilizing recommendations from the Delphi technique, including an expert group and piloting. A purposive sampling strategy was used, including head doctors from Norwegian EPHCCs (n = 169). Data were analyzed using the Statistical Package for the Social Sciences, and included descriptive statistics, Chi-Square tests and Shapiro-Wilks. Free-text answers were analyzed by content analysis.

RESULTS

A total of 64 head doctors responded to the questionnaire. The results show that 25% of the head doctors had experienced mass influx of patients at their EPHCC. In total 54.7% of Norwegian EPHCCs did not have disaster plans that consider mass influx situations. The majority of EPHCCs plan to recall staff one by one (60.3%) or through Short-Message-Systems (34.4%). Most EPHCCs had available telephone "alarm" lists (81.4%), that are updated regularly (60.9%). However, only 17.2% had plans that consider loss of mobile phone connection or internet. In total, 67,2% of the head doctors reported to have little experience with automatized staff recall systems, and 59,7% reported to have little knowledge about such systems. There were no significant difference between small and large EPHCCs in having plans or not.

CONCLUSION

Even though our results show that few EPHCCs experience mass influx of patients, it is important to be prepared when such incidents do occur. Our results indicate that it is still potential for improvement regarding plans for staff recall and implementation of staff recall systems at Norwegian EPHCCs. Involving national disaster medicine experts in the process of generating tools or checklists could aid when constructing disaster plans. Education and implementation of training for mass influx situations at all levels should always be highlighted.

Education and training as a key enabler of successful patient care in mass-casualty terrorist incidents

BACKGROUND AND PURPOSE

The increase in terrorist attacks with sometimes devastating numbers of victims has become a reality in Europe and has led to a fundamental change in thinking and a reorientation in many fields including health policy. The purpose of this original work was to improve the preparedness of hospitals and to provide recommendations for training.

MATERIAL AND METHODS

We conducted a retrospective literature search based on the Global Terrorism Database (GTD) for the period 2000 to 2017. Using defined search strategies, we were able to identify 203 articles. We grouped relevant findings into main categories with 47 statements and recommendations on education and training. In addition, we included data from a prospective questionnaire-based survey on this topic that we conducted at the 3rd Emergency Conference of the German Trauma Society (DGU) in 2019.

RESULTS

Our systematic review identified recurrent statements and recommendations. A key recommendation was that regular training should take place on scenarios that should be as realistic as possible and should include all hospital staff. Military expertise and competence in the management of gunshot and blast injuries should be integrated. In addition, medical leaders from German hospitals considered current surgical education and training to be insufficient for preparing junior surgeons to manage patients who have sustained severe injuries by terrorist events.

CONCLUSION

A number of recommendations and lessons learned on education and training were repeatedly identified. They should be included in hospital preparations for mass-casualty terrorist incidents. There appear to be deficits in current surgical training which may be offset by establishing courses and exercises.

Interdisciplinary Collaboration in International Crisis Medical Relief: A Look at the Nepal Earthquake and Ebola Relief Efforts

OBJECTIVE

This study explores interprofessional collaboration among medical and non-medical personnel planning and implementing international crisis health and medical relief efforts, and how disciplinary and professional background influences these activities.

METHODS

This study analyzes semi-structured interviews with individuals involved in organizations medical or health services to the Ebola epidemic in West Africa (2014-2016) or the 2015 Nepal earthquake.

RESULTS

Disciplinary background, sometimes coupled with organization role, shaped how relief workers engaged in the process of planning and implementing crisis medical relief. There were 3 thematic areas where these differences emerged: issue focus, problem -solving approaches, and decision-making approaches. Solutions from the field emerged as a fourth theme.

CONCLUSIONS

The study demonstrates medical relief required collaboration across medical and non-medical professions and highlights the importance of relief workers' disciplinary background in shaping the planning and implementation of crisis medical relief. Successful collaboration requires that people involved in crisis relief communicate the relevance of their own expertise, identify limits of their own and others' disciplinary perspective(s), seek out strengths in others' expertise, and can identify/ respond appropriately to others who do not see their own disciplinary limits, as well as learn these skills before engaging in relief.

Peritraumatic physical symptoms and the clinical trajectory of PTSD after a terrorist attack: a network model approach

Introduction: Following a mass casualty event, such as the Paris terrorist attacks of 13 November 2015, first responders need to identify individuals at risk of PTSD. Physical peritraumatic symptoms involving the autonomic nervous system may be useful in this task.Objective: We sought to determine the trajectory of physical response intensity in individuals exposed to the Paris terrorist attacks using repeated measures, and to examine its associations with PTSD. Using network modelling, we examined whether peritraumatic physical symptom associations differed by PTSD status.Methods: Physical reactions were assessed using the Subjective Physical Reactions Scale at three time points: peritraumatic by retrospective recall, then current at one year (8-18 months) and three years (30-42 months) after the attacks. Interaction networks between peritraumatic physical reactions were compared according to PTSD status.Results: On the one hand, the reported intensity of physical reactions was significantly higher in the PTSD group at all time points. On the other hand, using the dynamic approach, more robust positive interactions between peritraumatic physical reactions were found in the PTSD group one and three years after the attacks. Negative interactions were found in the no-PTSD group at one year. Peritraumatic physical numbness was found to be the most central network symptom in the PTSD group, whereas it was least central in the no-PTSD group.Discussion: Network analysis of the interaction between peritraumatic physical subjective responses, particularly physical numbness, may provide insight into the clinical course of PTSD. Our knowledge of the brain regions involved in dissociation supports the hypothesis that the periaqueductal grey may contribute to the process leading to physical numbing.Conclusions: Our findings highlight the role of peritraumatic somatic symptoms in the course of PTSD. Peritraumatic physical numbness appears to be a key marker of PTSD and its identification may help to improve early triage.

Development and Evaluation of Innovative and Practical Table-top Exercises Based on a Real Mass-Casualty Incident

PURPOSE

The aim of this work was to develop a table-top exercise (TTX) program for mass-casualty incident (MCI) response based on a real incident to evaluate the program.

METHODS

The TTX program was developed based on the 8 TTX design steps. Convenience sampling was adopted to recruit recently graduated physicians in China. After the TTX training, the participants completed a self-designed questionnaire, as well as the Simulation Design Scale (SDS) and Educational Practices in Simulation Scale (EPSS).

RESULTS

In total, 148 valid questionnaires were collected. The difficulty score of the TTX program was 3.69 ± 0.8. The participants evaluated the program highly, with a score of 4.72 ± 0.54 out of 5. Both the SDS and the EPSS had average scores higher than 4.5. Guided reflection/feedback (M = 4.68, SD = 0.41) and fidelity (M =4.66, SD = 0.57) were the 2 highest-rated SDS subscales. For the EPSS, diverse ways of learning and collaboration were the 2 highest-rated subscales. Multivariate stepwise regression analysis showed that the participants' evaluations of the TTX training course were related to the EPSS score, the difficulty rating, the evaluation of the instructional props, and the degree of participant involvement (F = 24.385, P < 0.001).

CONCLUSIONS

A TTX program for MCIs was developed based on the 2014 Shanghai New Year Crush. The TTX kit is practical and sophisticated, and it provides an effective strategy for MCI training.

Lessons learned from terror attacks: thematic priorities and development since 2001-results from a systematic review

Purpose

The threat of national and international terrorism remains high. Preparation is the key requirement for the resilience of hospitals and out-of-hospital rescue forces. The scientific evidence for defining medical and tactical strategies often feeds on the analysis of real incidents and the lessons learned derived from them. This systematic review of the literature aims to identify and systematically report lessons learned from terrorist attacks since 2001.

Methods

PubMed was used as a database using predefined search strategies and eligibility criteria. All countries that are part of the Organization for Economic Cooperation and Development (OECD) were included. The time frame was set between 2001 and 2018.

Results

Finally 68 articles were included in the review. From these, 616 lessons learned were extracted and summarized into 15 categories. The data shows that despite the difference in attacks, countries, and casualties involved, many of the lessons learned are similar. We also found that the pattern of lessons learned is repeated continuously over the time period studied.

Conclusions

The lessons from terrorist attacks since 2001 follow a certain pattern and remained constant over time. Therefore, it seems to be more accurate to talk about lessons identified rather than lessons learned. To save as many victims as possible, protect rescue forces from harm, and to prepare hospitals at the best possible level it is important to implement the lessons identified in training and preparation.

Estimating the Number of Civilian Casualties in Modern Armed Conflicts-A Systematic Review

Objective: To examine the possibility of estimating the number of civilian casualties in modern armed conflicts. Methods: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using PubMed, Scopus, and Web of Science search engines. The outcome was analyzed using a qualitative inductive thematic analysis. The scientific evidence of selected article was assessed, using the Health Evidence Quality Assessment Tool. Findings: The review of 66 included articles in this study indicates that with an increasing number of public health emergencies and the lack of vital elements of life such as water and food, emerging armed conflicts seem to be inevitable. In contrast to military-led cross-border traditional wars, modern armed conflicts affect internally on local communities and take civilian lives. Consequently, the measures and tools used in traditional military-led cross-border wars to adequately tally wounded and dead for many decades under the mandates of the International Humanitarian Law, is insufficient for modern warfare. While casualty counting during modern conflicts is deficient due to organizational, political or strategic reasons, the international organizations responsible for collecting such data (the International Federation of Red Cross and Red Crescent and International Institute of Humanitarian Law) face difficulties to access the conflict scene, resulting in under-reported, unreliable or no-reported data. Conclusion: There are challenges in estimating and counting the number of civilian casualties in modern warfare. Although the global need for such data is evident, the risks and barriers to obtaining such data should be recognized, and the need for new international involvement in future armed conflicts should be emphasized.

Learning from terrorist mass casualty incidents: a global survey

BACKGROUND

Reports published directly after terrorist mass casualty incidents frequently fail to capture difficulties that may have been encountered. An anonymised consensus-based platform may enable discussion and collaboration on the challenges faced. Our aim was to identify where to focus improvement for future responses.

METHODS

We conducted a mixed methods study by email of clinicians' experiences of leading during terrorist mass casualty incidents. An initial survey identified features that worked well, or failed to, during terrorist mass casualty incidents plus ongoing challenges and changes that were implemented as a result. A follow-up, quantitative survey measured agreement between responses within each of the themes using a Likert scale.

RESULTS

Thirty-three participants responded from 22 hospitals that had received casualties from a terrorist incident, representing 17 cities in low-middle, middle and high income countries. The first survey identified themes of sufficient (sometimes abundant) human resource, although coordination of staff was a challenge. Difficulties highlighted were communication, security, and management of blast injuries. The most frequently implemented changes were education on specific injuries, revising future plans and preparatory exercises. Persisting challenges were lack of time allocated to training and psychological well-being. The follow-up survey recorded highest agreement amongst correspondents on the need for re-triage at hospital (90% agreement), coordination roles (85% agreement), flexibility (100% agreement), and large-scale exercises (95% agreement).

CONCLUSION

This survey collates international experience gained from clinicians managing terrorist mass casualty incidents. The organisation of human response, rather than consumption of physical supplies, emerged as the main finding. NHSH Clinical Effectiveness Unit project registration number: 2020/21-036.

Teaching and Evaluation Methods of the Use of the Tourniquet in Severe Limb Bleeding among Health Care Professionals: A Systematic Review

INTRODUCTION AND OBJECTIVES

Massive hemorrhage (MH) is a growing pathology in military settings and increasingly in civilian settings; it is now considered a public health problem in the United States with large-scale programs. Tourniquets are the fastest and most effective intervention in MH if direct pressure is not effective.The Liaison Committee on Resuscitation (ILCOR) recognizes a knowledge gap in optimal education techniques for first aid providers. This review aims to describe training and evaluation methods for teaching tourniquet use to both health care and military professionals.

METHODS

The MEDLINE, CINAHL, WEB of Science, and Scopus databases were reviewed (from 2010 through April 2020). The quality of the selected studies was assessed using the Consolidated Standards of Reporting Trials (CONSORT) scale. Studies that met at least 65% of the included items were included. Data were extracted independently by two reviewers.

RESULTS

Ten of the 172 articles found were selected, of which three were randomized clinical trials. Heterogeneity was observed in the design of the studies and in the training and evaluative methods that limit the comparison between studies.

CONCLUSIONS

The results suggest that the training strategies studied are effective in improving knowledge, attitudes, and practical skills. There is no universal method, learning is meaningful but research should be directed to find out which ones work best.

The Great Belt train accident: the emergency medical services response

Background

Major incidents (MI) are rare occurrences in Scandinavia. Literature depicting Scandinavian MI management is scarce and case reports and research is called for. In 2019, a trailer falling off a freight train struck a passing high-speed train on the Great Belt Bridge in Denmark, killing eight people instantly and injuring fifteen people. We aim to describe the emergency medical services (EMS) response to this MI and evaluate adherence to guidelines to identify areas of improvement for future MI management.

Case presentation

Nineteen EMS units were dispatched to the incident site. Ambulances transported fifteen patients to a trauma centre after evacuation. Deceased patients were pronounced life-extinct on-scene. Radio communication was partly compromised, since 38.9% of the radio shifts were not according to the planned radio grid and presented a potential threat to patient outcome and personnel safety. Access to the incident site was challenging and delayed due to traffic congestion and safety issues.

Conclusion

Despite harsh weather conditions and complex logistics, the availability of EMS units was sufficient and patient treatment and evacuation was uncomplicated. Triage was relevant, but at the physicians’ discretion. Important findings were communication challenges and the consequences of difficult access to the incident site. There is a need for an expansion of capacity in formal education in MI management in Denmark.

Adaptations to practice and resilience in a paediatric major trauma centre during a mass casualty incident

BACKGROUND

Innovation and human adaptation in the face of unfolding catastrophe is the cornerstone of an effective systemwide response. Capturing, analysing, and disseminating this is fundamental in developing resilience for future events. The aim of this study was to understand the characteristics of adaptations to practice early in a paediatric major trauma centre during a mass casualty incident.

METHODS

A qualitative interview study of 40 healthcare staff at a paediatric major trauma centre in the immediate aftermath of a terrorist bombing was conducted. An inductive thematic analysis approach was used, followed by a deductive analysis of the identified adaptations informed by constructs of resilience engineering.

RESULTS

Five themes of adaptations to practice that enhanced the resilient performance of the hospital were identified: teamworking; psychologically supporting patients, families, and staff; reconfiguring infrastructure; working around the hospital electronic systems; and maintaining hospital safety. Examples of resilience potential in terms of respond, monitor, anticipate, and learn are presented.

CONCLUSIONS

Our study shows how adaptations to practice sustained the resilient performance of a paediatric major trauma centre during a mass casualty incident. Rapid, early capture of these data during a mass casualty incident provides key insights into enhancing future emergency preparedness, response, and resilience planning.

Changes in benzodiazepine use in the French general population after November 2015 terrorist attacks in Paris: an interrupted time series analysis of the national CONSTANCES cohort

OBJECTIVES

To determine whether the terrorist attacks occurring in Paris on November 2015 have changed benzodiazepine use in the French population.

DESIGN

Interrupted time series analysis.

SETTING

National population-based cohort.

PARTICIPANTS

90 258 individuals included in the population-based CONSTANCES cohort from 2012 to 2017.

OUTCOME MEASURES

Benzodiazepine use was evaluated according to two different indicators using objective data from administrative registries: weekly number of individuals with a benzodiazepine delivered prescriptions (BDP) and weekly number of defined daily dose (DDD). Two sets of analyses were performed according to sex and age (≤50 vs >50). Education, income and area of residence were additional stratification variables to search for at-risk subgroups.

RESULTS

Among women, those with younger age (incidence rate ratios (IRR)=1.18; 95% CI=1.05 to 1.32 for BDP; IRR=1.14; 95% CI=1.03 to 1.27 for DDD), higher education (IRR=1.23; 95% CI=1.03 to 1.46 for BDP; IRR=1.23; 95% CI=1.01 to 1.51 for DDD) and living in Paris (IRR=1.27; 95% CI=1.05 to 1.54 for BDP) presented increased risks for benzodiazepine use. Among participants under 50, an overall increase in benzodiazepine use was identified (IRR=1.14; 95% CI=1.02 to 1.28 for BDP and IRR=1.12; 95% CI=1.01 to 1.25 for DDD) and in several strata. In addition to women, those with higher education (IRR=1.22; 95% CI=1.02 to 1.47 for BDP), lower income (IRR=1.17; 95% CI=1.02 to 1.35 for BDP) and not Paris residents (IRR=1.13; 95% CI=1.02 to 1.26 for BDP and IRR=1.13; 95% CI=1.03 to 1.26 for DDD) presented increased risks for benzodiazepine use.

CONCLUSION

Terrorist attacks might increase benzodiazepine use at a population level, with at-risk subgroups being particularly concerned. Information and prevention strategies are needed to provide appropriate care after such events.

Case fatality inequalities of critically ill COVID-19 patients according to patient-, hospital- and region-related factors: a French nationwide study

Background

The COVID-19 sanitary crisis inflicted different challenges regarding the reorganization of the human and logistic resources, particularly in intensive care unit (ICU). Interdependence between regional pandemic burden and individual outcome remains unknown. The study aimed to assess the association between ICU bed occupancy and case fatality rate of critically ill COVID-19 patients.

Methods

A cross-sectional study was performed in France, using the national hospital discharge database from March to May, 2020. All patients admitted to ICU for COVID-19 were included. Case fatality was described according to: (i) patient’s characteristics (age, sex, comorbid conditions, ICU interventions); (ii) hospital’s characteristics (baseline ICU experience assessed by the number of ICU stays in 2019, number of ICU physicians per bed), and (iii) the regional outbreak-related profiles (workload indicator based on ICU bed occupancy). The determinants of lethal outcome were identified using a logistic regression model.

Results

14,513 COVID-19 patients were admitted to ICU; 4256 died (29.3%), with important regional inequalities in case fatality (from 17.6 to 33.5%). Older age, multimorbidity and clinical severity were associated with higher mortality, as well as a lower baseline ICU experience of the health structure. Regions with more than 10 days with ≥ 75% of ICU occupancy by COVID-19 patients experienced an excess of mortality (up to adjusted OR = 2.2 [1.9–2.6] for region with the highest occupancy rate of ICU beds).

Conclusions

The regions with the highest burden of care in ICU were associated with up to 2.2-fold increase of death rate.

[Safety aspects, emergency preparedness and hazard prevention in hospitals concerning mass casualty incidents (MCI)/terror-related MCI : Prospects on future challenges based on survey results from the 3rd emergency conference of the DGU]

Hintergrund

Weltweite terroristische Aktivitäten seit „9/11“ und folgend auch im europäischen Raum haben im Rahmen der Bewertung von kritischer Infrastruktur in Deutschland zu einem Umdenken auch hinsichtlich der Sicherheit an und in Kliniken geführt.

Ziel der Arbeit

Die vorliegende Publikation befasst sich mit der Bewertung vorliegender Konzepte zu Themen wie „Alarmierung“, „Sicherheit“, „Kommunikation“ und „Vorbereitung“ im vorgenannten Kontext.

Material und Methoden

Anhand einer Literatursichtung sowie einer Umfrage unter den Teilnehmern*innen der 3. Notfallkonferenz der DGU (Deutsche Gesellschaft für Unfallchirurgie) werden diese Thematik und die aktuell vorliegende Situation weiter analysiert und vorgestellt.

Ergebnisse

Die gewonnenen Daten verdeutlichen, dass ein Großteil der Kliniken zwar über eine Krankenhausalarm- und Einsatzplanung verfügt, jedoch die Frequenz der Aktualisierungen und die innerklinische Kommunikation zur Steigerung der Wahrnehmung eine deutliche Streuung zeigen.

Weiterhin verdeutlichen die Ergebnisse eine Heterogenität der vorliegenden innerklinischen Alarmierungskonzepte sowie einen Mangel an Sicherheitskonzepten und Kooperationen mit Sicherheits- und Wachdiensten. Zudem zeigt sich, dass die Thematik einer möglichen CBRN(chemical, biological, radiological, nuclear)-Bedrohung in der Risikoanalyse noch nicht adäquat wahrgenommen wird bzw. umgesetzt ist.

Diskussion

Zusammenfassend scheint die latente Bedrohung durch terroristische Aktivitäten dazu geführt zu haben, dass sich deutsche Kliniken in der Bewertung als kritische Infrastruktur mit der Thematik „Krankenhausalarm- und Einsatzplanung“ auseinandergesetzt und diese überwiegend auch umgesetzt haben. Allerdings zeigt sich für die nachgeordneten Bereiche und die aus der Alarmplanung ableitbaren Konsequenzen noch nicht die nötige Stringenz, um letztendlich adäquate Reaktionen in diesen besonderen Szenarien im Hinblick auf die Sicherheit in und an deutschen Kliniken zu gewährleisten.

Mass Casualty and the Role of the Anesthesiologist

The anesthesiologist, upon completion of their training, is expected to be the liaison to the operating room and the patient. Key components of the anesthesiologist's training and daily routine make them an ideal participant and leader when it comes to their potential involvement in a mass casualty event. Airway expertise, vascular access, ongoing triage, hemodynamic vigilance, resuscitation, and real-time adaptation to a changing and critical care environment are a few of the skills that encompass the daily routine and value the anesthesiologist brings to an emergency management team.

The BCD Triage Sieve outperforms all existing major incident triage tools: Comparative analysis using the UK national trauma registry population

BACKGROUND

Natural disasters, conflict, and terrorism are major global causes of death and disability. Central to the healthcare response is triage, vital to ensure the right care is provided to the right patient at the right time. The ideal triage tool has high sensitivity for the highest priority (P1) patients with acceptably low over-triage. This study compared the performance of major incident triage tools in predicting P1 casualty status in adults in the prospective UK Trauma Audit and Research Network (TARN) registry.

METHODS

TARN patients aged 16+ years (January 2008-December 2017) were included. Ten existing triage tools were applied using patients' first recorded pre-hospital physiology. Patients were subsequently assigned triage categories (P1, P2, P3, Expectant or Dead) based on pre-defined, intervention-based criteria. Tool performance was assessed by comparing tool-predicted and intervention-based priority status.

FINDINGS

195,709 patients were included; mortality was 7·0% (n=13,601); median Injury Severity Score (ISS) was 9 (IQR 9-17); 97·1% sustained blunt injuries. 22,144 (11·3%) patients fulfilled intervention-based criteria for P1 status, exhibiting higher mortality (12·8% vs. 5·0%, p<0.001), increased intensive care requirement (52·4% vs 5·0%, p<0.001), and more severe injuries (median ISS 21 vs 9, p<0.001) compared with P2 patients.In 16-64 year olds, the highest performing tool was the Battlefield Casualty Drills (BCD) Triage Sieve (Prediction of P1 status: 70·4% sensitivity, over-triage 70·9%, area under the receiver operating curve (AUC) 0·068 [95%CI 0·676-0·684]). The UK National Ambulance Resilience Unit (NARU) Triage Sieve had sensitivity of 44·9%; over-triage 56·4%; AUC 0·666 (95%CI 0·662-0·670). All tools performed poorly amongst the elderly (65+ years).

INTERPRETATION

The BCD Triage Sieve performed best in this nationally representative population; we recommend it supersede the NARU Triage Sieve as the UK primary major incident triage tool. Validated triage category definitions are recommended for appraising future major incidents.

Healthcare system impacts of the 2017 Manchester Arena bombing: evidence from a national trauma registry patient case series and hospital performance data

Introduction

In response to detonation of an improvised explosive device at the Manchester Arena on 22 May 2017, we aimed to use detailed information about injured patients flowing through hospital healthcare to objectively evaluate the preplanned responses of a regional trauma care system and to show how routinely collected hospital performance data can be used to assess impact on regional healthcare.

Methods

Data about injury severity, management and outcome for patients presenting to hospitals were collated using England’s major trauma registry for 30 days following hospital attendance. System-wide data about hospital performance were collated by National Health Service England’s North West Utilisation Management Unit and presented as Shewhart charts from 15 April 2017 to 25 June 2017.

Results

Detailed information was obtained on 153 patients (109 adults and 44 children) who attended hospital emergency departments after the incident. Within 6 hours, a network of 11 regional trauma care hospitals received a total of 138 patients (90%). For the whole patient cohort, median Injury Severity Score (ISS) was 1 (IQR 1–10) and median New ISS (NISS) was 2 (IQR 1–14). For the 75 patients (49%) attending a major trauma centre, median ISS was 7.5 (IQR 1–14) and NISS was 10 (IQR 3–22). Limb and torso body regions predominated when injuries were classified as major life threatening (Abbreviated Injury Scale>3). Ninety-three patients (61%) required hospital admission following emergency department management, with 21 (14%) requiring emergency damage control surgery and 24 (16%) requiring critical care. Three fatalities occurred during early resuscitative treatment and 150 (98%) survived to day 30. The increased system-wide hospital admissions and care activity was linked to increases in regional hospital care capacity through cancellations of elective surgery and increased community care. Consequently, there were sustained system-wide hospital service improvements over the following weeks.

Conclusions

The systematic collation of injured patient and healthcare system data has provided an objective evaluation of a regional major incident plan and provided insight into healthcare system resilience. Hospital patient care data indicated that a prerehearsed patient dispersal plan at incident scene was implemented effectively.

Assessment of the mass casualty triage during the November 2015 Paris area terrorist attacks: towards a simple triage rule

BACKROUND

Triage is key in the management of mass casualty incidents.

OBJECTIVE

The objective of this study was to assess the prehospital triage performed during the 2015 Paris area terrorist attack.

DESIGN SETTING AND PARTICIPANT

This was a retrospective cohort study that included all casualties of the attacks on 13 November 2015 in Paris area, France, that were admitted alive at the hospital within the first 24 h after the events. Patients were triaged as absolute emergency or relative emergency by a prehospital physician or nurse. This triage was then compared to the one of an expert panel that had retrospectively access to all prehospital and hospital files.

OUTCOMES MEASURES AND ANALYSIS

The primary endpoints were the rate of overtriage and undertriage, defined as number of patients misclassified in one triage category, divided by the total number of patients in this triage category.

MAIN RESULT

Among 337 casualties admitted to the hospital, 262 (78%) were triaged during prehospital care, with, respectively, 74 (28%) and 188 (72%) as absolute and relative emergencies. Among these casualties, the expert panel classified 96 (37%) patients as absolute emergencies and 166 (63%) as relative emergency. The rate of undertriage and overtriage was 36% [95% confidence interval (CI), 27-47%] and 8% (95% CI, 4-13%), respectively. Among undertriaged casualties, 8 (23%) were considered as being severely undertriaged. Among overtriaged casualties, 10 (77%) were considered as being severely overtriaged.

CONCLUSION

A simple prehospital triage for trauma casualties during the 13 November terrorist attack in Paris could have been performed triaged in 78% of casualties that were admitted to the hospital, with a 36% rate of undertriage and 8% of overtriage. Qualitative analysis of undertriage and overtriage indicate some possibilities for further improvement.

Civilian gunshot injuries in orthopaedics: a narrative review of ballistics, current concepts, and the South African experience

The incidence of civilian gunshot injuries is on the rise worldwide.Unfortunately, there is a lack of high-level evidence guiding management. The treatment of orthopaedic injuries from gunshots is complex and requires consideration of multiple aspects, including energy transfer to the tissue, severity of the wound, possible contamination, presence of fractures and associated injuries. With this narrative review we aim to discuss some of the relevant ballistics, current concepts, and controversies in the general management of civilian gunshot-related orthopaedic injuries based on the available evidence and personal experience. Important points which will be highlighted are the initial management in the emergency room, the assessment and management of soft tissue injuries, associated injuries, use of antibiotics, indication and techniques for fracture fixation, and gunshot injuries to joints.

The Development of Swedish Military Healthcare System: Part II-Re-evaluating the Military and Civilian Healthcare Systems in Crises Through a Dialogue and Study Among Practitioners

Introduction

Historical changes have transformed Sweden from being an offensive to a defensive and collaborative nation with national and international engagement, allowing it to finally achieve the ground for the civilian–military collaboration and the concept of a total defense healthcare. At the same time, with the decreasing number of international and interstate conflicts, and the military’s involvement in national emergencies and humanitarian disaster relief, both the need and the role of the military healthcare system within the civilian society have been challenged. The recent impact of the COVID-19 in the USA and the necessity of military involvement have led health practitioners to anticipate and re-evaluate conditions that might exceed the civilian capacity of their own countries and the need to have collaboration with the military healthcare. This study investigated both these challenges and views from practitioners regarding the benefits of such collaboration and the manner in which it would be initiated.

Material and Method

A primary study was conducted among responsive countries using a questionnaire created using the Nominal Group Technique. Relevant search subjects and keywords were extracted for a systematic review of the literature, according to the PRISMA model.

Results

The 14 countries responding to the questionnaire had either a well-developed military healthcare system or units created in collaboration with the civilian healthcare. The results from the questionnaire and the literature review indicated a need for transfer of military medical knowledge and resources in emergencies to the civilian health components, which in return, facilitated training opportunities for the military staff to maintain their skills and competencies.

Conclusions

As the world witnesses a rapid change in the etiology of disasters and various crises, neither the military nor the civilian healthcare systems can address or manage the outcomes independently. There is an opportunity for both systems to develop future healthcare in collaboration. Rethinking education and training in war and conflict is indisputable. Collaborative educational initiatives in disaster medicine, public health and complex humanitarian emergencies, international humanitarian law, and the Geneva Convention, along with advanced training in competency-based skill sets, should be included in the undergraduate education of health professionals for the benefit of humanity.

Family medicine practitioners' stress during the COVID-19 pandemic: a cross-sectional survey

BACKGROUND

The COVID-19 pandemic has shaken the world in early 2020. In France, General Practitioners (GPs) were not involved in the care organization's decision-making process before and during the first wave of the COVID-19 pandemic. This omission could have generated stress for GPs. We aimed first to estimate the self-perception of stress as defined by the 10-item Perceived Stress Score (PSS-10), at the beginning of the pandemic in France, among GPs from the Auvergne-Rhône-Alpes, a french administrative area severely impacted by COVID-19. Second, we aimed to identify factors associated with a self-perceived stress (PSS-10 ≥ 27) among socio-demographic characteristics of GPs, their access to reliable information and to personal protective equipment during the pandemic, and their exposure to well established psychosocial risk at work.

METHODS

We conducted an online cross-sectional survey between 8th April and 10th May 2020. The self-perception of stress was evaluated using the PSS-10, so to see the proportion of "not stressed" (≤20), "borderline" (21 ≤ PSS-10 ≤ 26), and "stressed" (≥27) GPs. The agreement to 31 positive assertions related to possible sources of stress identified by the scientific study committee was measured using a 10-point numeric scale. In complete cases, factors associated with stress (PSS-10 ≥ 27) were investigated using logistic regression, adjusted on gender, age and practice location. A supplementary analysis of the verbatims was made.

RESULTS

Overall, 898 individual answers were collected, of which 879 were complete. A total of 437 GPs (49%) were stressed (PSS-10 ≥ 27), and 283 GPs (32%) had a very high level of stress (PSS-10 ≥ 30). Self-perceived stress was associated with multiple components, and involved classic psychosocial risk factors such as emotional requirements. However, in this context of health crisis, the primary source of stress was the diversity and quantity of information from diverse sources (614 GPs (69%, OR = 2.21, 95%CI [1.40-3.50], p < 0.001). Analysis of verbatims revealed that GPs felt isolated in a hospital-based model.

CONCLUSION

The first wave of the pandemic was a source of stress for GPs. The diversity and quantity of information received from the health authorities were among the main sources of stress.

Medicine at mass gatherings: current progress of preparedness of emergency medical services and disaster medical response during 2020 Tokyo Olympic and Paralympic Games from the perspective of the Academic Consortium (AC2020)

Mass gatherings are events characterized by “the concentration of people at a specific location for a specific purpose over a set period of time that have the potential to strain the planning and response resources of the host country or community.” Previous reports showed that, as a result of the concentration of people in the limited area, injury and illness occurred due to several factors. The response plan should aim to provide timely medical care to the patients and to reduce the burden on emergency hospitals, and to maintain a daily emergency medical services system for residents of the local area. Although a mass gathering event will place a significant burden on the local health‐care system, it can provide the opportunity for long‐term benefits of public health‐care and improvement of daily medical service systems after the end of the event. The next Olympic and Paralympic Games will be held in Tokyo, during which mass gatherings will occur on a daily basis in the context of the coronavirus disease (COVID‐19) epidemic. The Academic Consortium on Emergency Medical Services and Disaster Medical Response Plan during the Tokyo Olympic and Paralympic Games in 2020 (AC2020) was launched 2016, consisting of 28 academic societies in Japan, it has released statements based on assessments of medical risk and publishing guidelines and manuals on its website. This paper outlines the issues and countermeasures for emergency and disaster medical care related to the holding of this big event, focusing on the activities of the academic consortium.

French civilian surgical expertise still inadequately prepared for mass casualties 3 years after major terror attacks in Paris (2015) and Nice (2016)

BACKGROUND

Three years after the terror attacks in Paris and Nice, this study aims to determine the level of interest, the technical skills and level of surgical activity in exsanguinating trauma care for a nonselected population of practicing French surgeons.

METHODS

A questionnaire was sent between July and December 2017 to French students and practicing surgeons, using the French Surgical Colleges' mailing lists. Items analyzed included education, training, interest and clinical activity in trauma care and damage-control surgery (DCS).

RESULTS

622 questionnaires were analyzed and was composed of 318 (51%) certificated surgeons, of whom 56% worked in university teaching hospitals and 47% in Level I trauma centers (TC1); 44% were digestive surgeons and 7% were military surgeons. The mean score of 'interest in trauma care' was 8/10. Factors associated with a higher score were being a resident doctor (p = 0.01), a digestive surgeon (p = 0.0013), in the military (p = 1,71 × 10) and working in TC1 (p = 0.034). The mean "DCS techniques knowledge" score was 6.2/10 and factors significantly associated with a higher score were being a digestive surgeon (respectively, p = 0.0007 and p = 0.001) and in the military (respectively p = 1.74 × 10 and p = 3.94 × 10). Reported clinical activity in trauma and DCS were low. Additional continuing surgical education courses in trauma were completed by 23% of surgeons.

CONCLUSION

French surgeons surveyed showed considerable interest in trauma care and treatment. Despite this, and regardless of surgical speciality, their theoretical and practical knowledge of necessary DCS skills remain inadequate.

Immediate response to major incidents: defining an immediate responder!

PURPOSE

There is a gap in time between the occurrence of a mass casualty incident (MCI) and the arrival of the first responders to the scene, which offers an opportunity for the public (immediate responders) to perform life-saving measures. The purpose of this study was to identify these measures and the public's willingness to conduct them.

METHOD

An extensive literature review was performed to identify the possible measures that can be undertaken by the public. A group of experts were asked to prioritize and rank the feasibility of performing the measures by the public. Finally, the public was asked whether they were willing to do the chosen measures before and after an appropriate education.

RESULTS

Twenty different measures were identified and presented in a questionnaire as statements, which were prioritized and ranked by the expert group into four categories: what (1) should be done, (2) is good to know how, (3) is not necessary to know, and (4) should not be done. All statements were converted into understandable statements and were sent to the public. There were some differences and some agreements between the experts and the public regarding what an immediate responder should do. However, the willingness of the public to perform most of the measures was high and increased after being offered an appropriate education.

CONCLUSION

The use of immediate responders is a life-saving approach in MCIs and in situations when every minute counts and every human resource is an invaluable asset. Multiple steps, such as education, empowerment, and access, should be taken into consideration to enable bystanders to effectively help struggling survivors.

UK healthcare staff experiences and perceptions of a mass casualty terrorist incident response: a mixed-methods study

Introduction

System learning from major incidents is a crucial element of improving preparedness for response to any future incidents. Sharing good practice and limitations stimulates further actions to improve preparedness and prevents duplicating mistakes.

Methods

This convergent parallel mixed methods study comprises data from responses to an online survey and individual interviews with healthcare staff who took part in the responses to three terrorist incidents in the UK in 2017 (Westminster Bridge attack, Manchester Arena Bombing and London Bridge attack) to understand limitations in the response and share good practices.

Results

The dedication of NHS staff, staff availability and effective team work were the most frequently mentioned enabling factors in the response. Effective coordination between teams and a functional major incident plan facilitated an effective response. Rapid access to blood products, by positioning the blood bank in the ED, treating children and parents together and sharing resources between trauma centres were recognised as very effective innovative practices. Recent health emergency preparedness exercises (HEPEs) were valued for preparing both Trusts and individual staff for the response. Challenges included communication between ambulance services and hospitals, difficulties with patient identification and tracking and managing the return to ‘normal’ work patterns post event. Lack of immediately available clinical protocols to deal with blast injuries was the most commonly mentioned clinical issue. The need for psychosocial support for responding and supporting staff was identified.

Discussion

Between-agencies communication and information sharing appear as the most common recurring problems in mass casualty incidents (MCIs). Recent HEPEs, which allowed teams, interdisciplinary groups, and different agencies to practice responding to similar simulated incidents, were important and informed actions during the real response. Immediate and delayed psychosocial support should be in place for healthcare staff responding to MCIs.

An overview of forensic operations performed following the terrorist attacks on November 13, 2015, in Paris

On the evening of November 13, 2015, the city of Paris and its surroundings was hit by a series of attacks committed by terrorist groups, using firearms and explosives. The final toll was 140 people deceased (130 victims and 10 terrorists or their relatives) and more than 413 injured, making these attacks the worst mass killings ever recorded in Paris in peacetime. This article presents the forensic operations carried out at the Medicolegal Institute of Paris (MLIP) following these attacks. A total of 68 autopsies of bodies or body fragments and 83 external examinations were performed within 7 days, and the overall forensic operations (including formal identification of the latest victims) were completed 10 days after the attacks. Over this period, 156 body presentations (some bodies were presented several times) were provided to families or relatives. Regarding the 130 civilian casualties, 129 died from firearm wounds and one died from blast injuries after an explosion. Of the 10 terrorists or their relatives who were killed, eight died from suicide bombing, one was shot by police and one died from crush injuries due to partial collapse of a building following the police raid against a terrorist’s hideout after the attacks. All mass shootings were perpetrated with AK-47 or Zastava M70 assault rifles using 7.62 mm × 39 mm cartridges. In the case of ballistic injuries, death was most often obviously caused by craniocerebral injuries, extensive organ lacerations and/or massive haemorrhage. Among the terrorists killed by bombing, the lesion patterns were body transection, multiple amputations, extreme organ lacerations and the presence of foreign bodies owing to the shrapnel load (steel nuts, glass fragments) or the explosive charge fastening system of the devices. This discussion highlights the particular difficulties of interpretation encountered within the framework of ballistic injuries, a conclusion that should lead to a modest and realistic approach in these exceptional situations where forensic operations involve a very large number of victims in a constrained time.

[Exit wave plan for structured secondary patient distribution : Logistic concept for mass victims of terrorist attacks]

BACKGROUND

Following a terrorist attack a second hit is to be feared. The adequate reaction of the emergency services on site is to clear the scene. Since in such cases no treatment areas are set up at the scene of the incident, the injured are quickly admitted to the nearest hospital, either by themselves or by the emergency services and are largely untreated. Therefore, the hospital has to be ready to take in a significantly larger number of injured people in a very short period of time than after a conventional mass casualty incident. Due to the conceivably large number of wounded persons the emergency department can ensure primary medical care but nowhere near all casualties admitted to the hospital can be definitively treated.

OBJECTIVE

In order to provide injured patients with individual medical care after initial treatment according to the criteria of damage control resuscitation, a concept should be developed that enables a well-organized secondary transfer to receiving hospitals with appropriate equipment.

MATERIAL AND METHODS

Within a radius of 100 km from Ulm, all hospitals certified by the German Society for Trauma Surgery were contacted and asked to indicate how many emergency patients of the triage categories T1 (red), T2 (yellow) and T3 (green) could be admitted and treated around the clock (24/7). Special features such as a helicopter landing pad, neurosurgical care and pediatric traumatology care were considered.

RESULTS

Of the 32 hospitals within a 100 km radius of Ulm 29 (91%) provided information on the admission capacity. In these hospitals 45 T1, 121 T2 and 333 T3 patients could be admitted around the clock (24/7). A helicopter landing pad is available at 26 of the 29 hospitals (90%), 11 hospitals (38%) can treat patients for emergency neurosurgery and 18 hospitals (62%) have the possibility of pediatric traumatological emergency care. Based on this information the structured exit wave plan was developed, which enables a secondary transfer of at least 100 patients to qualified trauma centers.

CONCLUSION

The University Hospital of Ulm has made preparations to admit at least 100 injured patients for initial medical treatment following a terrorist attack. This corresponds to 10% of the hospital beds as required in the literature. Together with the neighboring Military Hospital and the University and Rehabilitation Hospital Ulm up to 300 injured patients can be treated; however, the number of available intensive care unit (ICU) beds and capacities in normal wards for definitive care is much lower, therefore, patients treated according to the principles of damage control resuscitation have to be relocated. By documenting the capacity of the hospitals within a 100 km radius around Ulm and taking their specific features into account, an exit wave plan could be created that enables patient distribution for definitive care without time-consuming procedures.

A national healthcare response to intensive care bed requirements during the COVID-19 outbreak in France

Background

Whereas 5415 Intensive Care Unit (ICU) beds were initially available, 7148 COVID-19 patients were hospitalised in the ICU at the peak of the outbreak. The present study reports how the French Health Care system created temporary ICU beds to avoid being overwhelmed.

Methods

All French ICUs were contacted for answering a questionnaire focusing on the available beds and health care providers before and during the outbreak.

Results

Among 336 institutions with ICUs before the outbreak, 315 (94%) participated, covering 5054/5531 (91%) ICU beds. During the outbreak, 4806 new ICU beds (+95% increase) were created from Acute Care Unit (ACU, 2283), Post Anaesthetic Care Unit and Operating Theatre (PACU & OT, 1522), other units (374) or real build-up of new ICU beds (627), respectively. At the peak of the outbreak, 9860, 1982 and 3089 ICU, ACU and PACU beds were made available.

Before the outbreak, 3548 physicians (2224 critical care anaesthesiologists, 898 intensivists and 275 from other specialties, 151 paediatrics), 1785 residents, 11,023 nurses and 6763 nursing auxiliaries worked in established ICUs. During the outbreak, 2524 physicians, 715 residents, 7722 nurses and 3043 nursing auxiliaries supplemented the usual staff in all ICUs. A total number of 3212 new ventilators were added to the 5997 initially available in ICU.

Conclusion

During the COVID-19 outbreak, the French Health Care system created 4806 ICU beds (+95% increase from baseline), essentially by transforming beds from ACUs and PACUs. Collaboration between intensivists, critical care anaesthesiologists, emergency physicians as well as the mobilisation of nursing staff were primordial in this context.

Emergency management and internal audit of emergency preparedness of pre-hospital emergency care

One of the negative components of international travel is the higher likelihood of emergencies that affect a large number of people (mass negative impact on health), for example the transmission of infectious diseases, as e.g. SARS CoV-2 pandemic. The frequency and sources of mass-casualty incidents are currently changing dynamically, especially with the onset of terrorist attacks and large-scale natural disasters. Health services and emergency medical service (EMS) take part in addressing these emergencies. For this reason, this paper deals with the EMS emergency preparedness in the Czech Republic for an emergency events with a large number of affected people. EMS in the Czech Republic are not provided by the state but by individual regions. EMS in the Czech Republic do not have central management, nor do they use uniform data documentation. The investigation of the current situation has shown that the attitudes of EMS in individual regions of the Czech Republic to the tasks of emergency preparedness for mass casualty incidents are not identical. The current method of evaluating improvements in the quality of EMS emergency preparedness lacks consistency and is not comprehensively supervised. To tackle this, the paper presents an internal audit methodology for assessing the level of emergency preparedness of the emergency medical services. The authors therefore defined the decisive criteria and indicators assessing the quality level of EMS emergency preparedness at major disaster with multiple victim incident. When developing the methodological procedure of the preparedness evaluation, an algorithm was chosen, based on the gradual verification of the evaluation criteria and indicators by an expert group. Some findings and recommendations based on a research carried out in EMS in individual regions of the Czech Republic are presented.

Addition of terlipressin to initial volume resuscitation in a pediatric model of hemorrhagic shock improves hemodynamics and cerebral perfusion

Hemorrhagic shock is one of the leading causes of mortality and morbidity in pediatric trauma. Current treatment based on volume resuscitation is associated to adverse effects, and it has been proposed that vasopressors may be used in the pharmacological management of trauma. Terlipressin has demonstrated its usefulness in other pediatric critical care scenarios and its long half-life allows its use as a bolus in an outpatient critical settings. The aim of this study was to analyze whether the addition of a dose of terlipressin to the initial volume expansion produces an improvement in hemodynamic and cerebral perfusion at early stages of hemorrhagic shock in an infant animal model. We conducted an experimental randomized animal study with 1-month old pigs. After 30 minutes of hypotension (mean arterial blood pressure [MAP]<45 mmHg) induced by the withdrawal of blood over 30 min, animals were randomized to receive either normal saline (NS) 30 mL/kg (n = 8) or a bolus of 20 mcg/kg of terlipressin plus 30 mL/kg of normal saline (TP) (n = 8). Global hemodynamic and cerebral monitoring parameters, brain damage markers and histology samples were compared. After controlled bleeding, significant decreases were observed in MAP, cardiac index (CI), central venous pressure, global end-diastolic volume index (GEDI), left cardiac output index, SvO₂, intracranial pressure, carotid blood flow, bispectral index (BIS), cerebral perfusion pressure (CPP) and increases in systemic vascular resistance index, heart rate and lactate. After treatment, MAP, GEDI, CI, CPP and BIS remained significantly higher in the TP group. The addition of a dose of terlipressin to initial fluid resuscitation was associated with hemodynamic improvement, intracranial pressure maintenance and better cerebral perfusion, which would mean protection from ischemic injury. Brain monitoring through BIS was able to detect changes caused by hemorrhagic shock and treatment.
