Abstract
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 Outdated communication equipment, overwhelmed communication services, failure due to damaged infrastructure by the terrorist attack itself, and lack of training were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 Malfunctioning of (outdated) telecommunication services, inadequate training in the use of communication devices, unfortunate damage of telecommunication network infrastructure were also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.

Abstract
Although most trauma centers have experience with the imaging and management of gunshot wounds, in most regions blast wounds such as the ones encountered in terrorist attacks with the use of improvised explosive devices (IEDs) are infrequently encountered outside the battlefield. As global terrorism becomes a greater concern, it is important that radiologists, particularly those working in urban trauma centers, be aware of the mechanisms of injury and the spectrum of primary, secondary, tertiary, and quaternary blast injury patterns. Primary blast injuries are caused by barotrauma from the initial increased pressure of the explosive detonation and the rarefaction of the atmosphere immediately afterward. Secondary blast injuries are caused by debris carried by the blast wind and most often result in penetrating trauma from small shrapnel. Tertiary blast injuries are caused by the physical displacement of the victim and the wide variety of blunt or penetrating trauma sustained as a result of the patient impacting immovable objects such as surrounding cars, walls, or fences. Quaternary blast injuries include all other injuries, such as burns, crush injuries, and inhalational injuries. Radiography is considered the initial imaging modality for assessment of shrapnel and fractures. Computed tomography is the optimal test to assess penetrating chest, abdominal, and head trauma. The mechanism of blast injuries and the imaging experience of the victims of the Boston Marathon bombing are detailed, as well as musculoskeletal, neurologic, gastrointestinal, and pulmonary injury patterns from blast injuries.

Abstract
INTRODUCTION Terrorists have used the explosive device successfully globally, with their effects extending beyond the resulting injuries. Suicide bombings, in particular, are being increasingly deployed due to the devastating effect of a combination of high lethality and target accuracy. The aim of this study was to identify trends and analyse the demographics and casualty figures of terrorist bombings worldwide. METHODS Analysis of the Global Terrorism Database (GTD) and a PubMed/Embase literature search (keywords "terrorist", and/or "suicide", and/or "bombing") from 1970 to 2014 was performed. RESULTS 58,095 terrorist explosions worldwide were identified in the GTD. 5.08% were suicide bombings. Incidents per year are increasing (P<0.01). Mean casualty statistics per incidents was 1.14 deaths and 3.45 wounded from non-suicide incidents, and 10.16 and 24.16 from suicide bombings (p<0.05). The kill:wounded ratio was statistically higher in suicide attacks than non-suicide attacks, 1:1.3 and 1:1.24 respectively (p<0.05). The Middle East witnessed the most incidents (26.9%), with Europe (13.2%) ranked 4th. The literature search identified 41 publications reporting 167 incidents of which 3.9% detailed building collapse (BC), 60.8% confined space (CS), 23.5% open space (OS) and 11.8% semi-confined space (SC) attacks. 60.4% reported on suicide terrorist attacks. Overall 32 deaths and 180 injuries per incident were seen, however significantly more deaths occurred in explosions associated with a BC. Comparing OS and CS no difference in the deaths per incident was seen, 14.2(SD±17.828) and 15.63 (SD±10.071) respectively. However OS explosions resulted in significantly more injuries, 192.7 (SD±141.147), compared to CS, 79.20 (SD±59.8). Extremity related wounds were the commonest injuries seen (32%). DISCUSSION/CONCLUSION Terrorist bombings continue to be a threat and are increasing particularly in the Middle East. Initial reports, generated immediately at the scene by experienced coordination, on the type of detonation (suicide versus non-suicide), the environment of detonation (confined, open, building collapse) and the number of fatalities, and utilising the Kill:Wounded ratios found in this meta-analysis, can be used to predict the number of casualties and their likely injury profile of survivors to guide the immediate response by the medical services and the workload in the coming days.

Abstract
OBJECTIVE We discuss the strengths of the medical response to the Boston Marathon bombings that led to the excellent outcomes. Potential shortcomings were recognized, and lessons learned will provide a foundation for further improvements applicable to all institutions. BACKGROUND Multiple casualty incidents from natural or man-made incidents remain a constant global threat. Adequate preparation and the appropriate alignment of resources with immediate needs remain the key to optimal outcomes. METHODS A collaborative effort among Boston's trauma centers (2 level I adult, 3 combined level I adult/pediatric, 1 freestanding level I pediatric) examined the details and outcomes of the initial response. Each center entered its respective data into a central database (REDCap), and the data were analyzed to determine various prehospital and early in-hospital clinical and logistical parameters that collectively define the citywide medical response to the terrorist attack. RESULTS A total of 281 people were injured, and 127 patients received care at the participating trauma centers on that day. There were 3 (1%) immediate fatalities at the scene and no in-hospital mortality. A majority of the patients admitted (66.6%) suffered lower extremity soft tissue and bony injuries, and 31 had evidence for exsanguinating hemorrhage, with field tourniquets in place in 26 patients. Of the 75 patients admitted, 54 underwent urgent surgical intervention and 12 (22%) underwent amputation of a lower extremity. CONCLUSIONS Adequate preparation, rapid logistical response, short transport times, immediate access to operating rooms, methodical multidisciplinary care delivery, and good fortune contributed to excellent outcomes.

Abstract
PURPOSE To review the frequency, different patterns, anatomic severity, management, and prognosis of abdominal injuries in survivors of explosions, according to the main mechanism of injury. METHODS A MEDLINE search was conducted from January 1982 to August 2013, including the following MeSH terms: blast injuries, abdominal injuries. EMBASE was also searched, with the same entries. Abdominal blast injuries (ABIs) have been defined as injuries resulting not only from the effects of the overpressure on abdominal organs, but also from the multimechanistic effects and projectile fragments resulting from the blast. Special emphasis was placed on the detailed assessment of ABIs in patients admitted to GMUGH (Gregorio Marañón University General Hospital) after the Madrid 2004 terrorist bombings, and in patients admitted to HYMC (Hillel Yaffe Medical Centre) in Hadera (Israel) following several bombing episodes. The anatomic severity of injuries was assessed by the abdominal component of the AIS, and the overall anatomic severity of casualties was assessed by means of the NISS. RESULTS Abdominal injuries are not common in survivors of terrorist explosions, although they are a frequent finding in those immediately killed. Primary and tertiary blast injuries have predominated in survivors from explosions in enclosed spaces reported outside of Israel. In contrast, secondary blast injuries causing fragmentation wounds were predominant in suicide bombings in open and/or semi-confined spaces, mainly in Israel, and also in military conflicts. Multiple perforations of the ileum seem to be the most common primary blast injury to the bowel, but delayed bowel perforations are rare. Secondary blast injuries carry the highest anatomic severity and mortality rate. Most of the deaths assessed occurred early, with hemorrhagic shock from penetrating fragments as the main contributing factor. The negative laparotomy rate has been very variable, with higher rates reported, in general, from civilian hospitals attending a large number of casualties. CONCLUSIONS The pattern, severity, management, and prognosis of ABI vary considerably, in accordance with the main mechanism of injury.

Is Overtriage Associated With Increased Mortality? Insights From a Simulation Model of Mass Casualty Trauma Care. Disaster Med Public Health Prep 2013; 1:S14-24.

Abstract
ABSTRACTPurpose: To examine the relationship between overtriage and critical mortality after a mass casualty incident (MCI) using a simulation model of trauma system response.Methods: We created a discrete event simulation model of trauma system management of MCIs involving individual patient triage and treatment. Model variables include triage performance, treatment capability, treatment time, and time-dependent mortality of critically injured patients. We model triage as a variable selection process applied to a hypothetical population of critically and noncritically injured patients. Treatment capability is represented by staffed emergency department trauma bays with associated staffed operating rooms that are recycled after each use. We estimated critical and noncritical patient treatment times and time-dependent mortality rates from the trauma literature.Results: In this simulation model, overtriage, the proportion of noncritical patients among all of those labeled as critical, has a positive, negative, or variable association with critical mortality depending on its etiology (ie, related to changes in triage sensitivity or to changes in the prevalence and total number of critical patients). In all of the modeled scenarios, the ratio of critical patients to treatment capability has a greater impact on critical mortality than overtriage level or time-dependent mortality assumption.Conclusions: Increasing overtriage may have positive, negative, or mixed effects on critical mortality in this trauma system simulation model. These results, which contrast with prior analyses describing a positive linear relationship between overtriage and mortality, highlight the need for alternative metrics to describe trauma system response after MCIs. We explore using the relative number of critical patients to available and staffed treatment units, or the critical surge to capability ratio, which exhibits a consistent and nonlinear association with critical mortality in this model.

Abstract
AbstractIntroduction:Bombings, including the 1995 Oklahoma City bombing, remain an important public health threat. However, there has been little investigation into the impressions of injury risk or protective factors of bombing survivors.Objective:This study analyzes Oklahoma City bombing survivors' impressions of factors that influenced their risk of injury, and validates a hazard timeline outlining phases of injury risk in a building bombing.Methods:In-depth, semi-structured interviews were conducted within a sample of Oklahoma City bombing survivors. Participants included 15 injured and uninjured survivors, who were located in three buildings surrounding the detonation site during the attack.Results:Risk factor themes included environmental glass, debris, and entrapment. Protective factors included knowledge of egress routes, shielding behaviors to deflect debris, and survival training. Building design and health status were reported as risk and protective factors. The hazard timeline was a useful tool, but should be modified to include a lay rescue phase. The combination of a narrative approach and direct questioning is an effective method of gathering the perceptions of survivors.Conclusions:Investigating survivors' impressions of building bombing hazards is critical to capture injury exposures, behavior patterns, and decision-making processes during actual events, and to identify interventions that will be supported by survivors.

Abstract
AbstractDuring the morning rush hour on Thursday, 07 July 2005, a series of four bombs exploded, affecting London's public transport system.These terrorist attacks killed 52 people and injured >700.A majorincident was declared, and the Royal London Hospital (RLH) was a primary receiving hospital.A total of 194 patients presented to the RLH.Twenty-seven patients required admission. A total of 11 amputations were performed on eight patients. One patient died intra-operatively.Another patient died on Day 6 due to complications related to a head injury.Coordination is vital to the implementation of the hospital's Major Incident Plan in such an emergency. Subsequent internal reviews of the response of the RLH on 07 July 2005 highlighted problems with communication and documentation, as well as the need for extra staffing.These areas should be improved for the management of future major incidents.

Abstract
OBJECTIVE The purpose of this study was to evaluate the impact of the use of 64-MDCT and volume image reading on the radiologic workflow during a mass casualty incident simulation. MATERIALS AND METHODS For this simulation, casualties were taken to our level I trauma center, and triage was done with whole-body 64-MDCT. The complete raw dataset of thin-section images was sent to a dedicated 3D workstation for further interpretation and simultaneous reformations. This new reading method is called volume image reading. Several time frames were documented to evaluate the workflow: examination time, time needed for image processing, and mean image transfer rates. The results were compared with those of a previous study using a 4-MDCT with axial images only and transfer of data to a PACS. RESULTS The time for complete image processing (acquisition, reconstruction, and transfer) for 64-MDCT was 4.1 minutes (range, 3.9-4.3 minutes) compared with 9.0 minutes (range, 6.4-10.2 minutes) for 4-MDCT (p ≤ 0.001). The image processing capacity was 14.8 examinations/h for 64-MDCT compared with 6.7 examinations/h for 4-MDCT. The mean number of images was 953 for 64-MDCT compared with 202 for 4-MDCT (p ≤ 0.001). There were no significant differences between 64- and 4-MDCT for the time needed to prepare patients. CONCLUSION The use of 64-MDCT with volume image reading led to evident advantages in the radiologic trauma workflow compared with 4-MDCT. Reading of the full image set including reformations can be initiated earlier with volume image reading.

Abstract
The purpose of this study was to evaluate the response to an automated alarm system of a radiology department during a mass casualty incident simulation. An automated alarm system provided by an external telecommunications provider handling up to 480 ISDN lines was used at a level I trauma center. During the exercise, accessibility, availability, and estimated time of arrival (ETA) of the called in staff were recorded. Descriptive methods were used for the statistical analysis. Of the 49 employees, 29 (59%) were accessible, of which 23 (79%) persons declared to be available to come to the department. The ETA was at an average 29 min (SD ±23). Radiologists and residents reported an ETA to their workplace almost two times shorter compared with technicians (19 ± 16 and 22 ± 16 vs. 40 ± 27 min, p > 0.05). Additional staff reserve is crucial for handling mass casualty incidents. An automated alarm procedure might be helpful. However, the real availability of the employees could not be exactly determined because of unpredictable parameters. But our results allow estimation of the manpower reserve and calculation of maximum radiology service capacities.

Abstract
BACKGROUND In Hannover and in nationwide contingency plans there are clear instructions for the medical care of mass casualties which are designed to cope with 50 to a maximum of 200 patients. Disaster simulations and practical exercises in Hannover regarding EXPO 2000 and the FIFA World Cup 2006 showed a very good and effective prehospital treatment and management up to a number of about 200 patients. Due to infrastructural settings a scenario with up to 1,000 (MANV IV) patients in the region of Hannover was beyond the capacity of existing concepts for the management of mass casualties, which comprised initial medical care at the on-site treatment area and subsequent transport to local or regional hospitals for definitive management. A new practicable and well trained model was necessary to improve the hospital admission and primary treatment capacity (Erstversorgungsklinik--EVK). In the case of MANV IV it was proposed that the tasks of on-site treatment area should be concentrated on triage and the stabilization of severely injured victims with immediate transport to special primary care hospitals. The main task of these hospitals was further stabilization of patients for inhospital care or further transport to other special facilities. METHODS The main aim of the study was, after the initial trauma scenario, to provide the logistical and personal background for the fastest possible advanced life support and the further treatment of more than 60 severely injured patients at a city hospital with trauma centre level I experience. The timescale from the first alarm until the hospital was ready for action was approximately 60 min. To gain knowledge about the regional implementation of the whole logistic scenario in the case of MANV IV and to practice detailed questioning, a major casualty training was needed. This resulted in a large targeted disaster medical training with a realistic situation simulation on the 25.03.2006 including the Diakoniekrankenhaus Friederikenstift under the aspect of a special primary care hospital (EVK) working at full capacity. RESULTS The AWD arena in Hannover was the site of a simulated major casualty event resulting in 620 patients with various penetrating or blunt trauma injuries. Within 60 min of the first alarm call the admission and casualty treatment capacity at the Diakoniekrankenhaus Friederikenstift was increased up to approximately 60 patients including 30 ventilated patients. After initial inspection of 78 patients according to the ATLS criteria advanced life support was performed (airway management, volume resuscitation, basic diagnostic and surgical techniques) by flexible treatment teams (including physicians of all other faculties) in 3 treatment corridors within 135 min. Of the patients 69 were admitted to the wards and intensive care units, 5 were discharged after ambulant treatment and 3 patients were transferred to an eye and ENT hospital. Of the patients 10 had already been intubated on arrival, another 6 patients were intubated in the treatment corridors. Simulations of 4 urgent laparatomies, 2 trepanations, 1 artery seam, osteosynthesis of 3 perforating fractures was performed in the operating theatre. A total of 6 extremity fractures were immobilized by a fixateur externe, 7 chest tubes were placed and 43 surgical wound dressings were performed in the treatment corridors. There was no significant shortage of logistical or personal resources. CONCLUSION In a major disaster with more than 200 seriously injured patients the EVK model is a practicable and regional well tried solution that could increase the capacity of hospital admissions and advanced trauma life support, regardless of the type of casualty, season or weather conditions. It is possible to reduce the interval to advanced trauma life support, temporary fracture stabilization (damage control) and definitive surgical care by means of rapid and targeted utilization of resources and manpower. Physicians involved in the initial treatment play a key role and have to be highly trained (ATLS). The EVK model is variable and can easily be established and adapted to regional conditions at basic regional hospitals as well as at level I trauma centers.

Abstract
A 3-year-old, intact male, mixed breed dog was presented with a complaint of acute blindness. Ten days previously, the area where the dog was walking came under a rocket attack, and a rocket landed and exploded 300 meters away from the dog. Physical examination was unremarkable. Ophthalmoscopic examination revealed posterior segment fibrin clots and extensive vitreal hemorrhage in the right eye. A total retinal detachment (360 degrees retinal dialysis) with no evidence of hemorrhage was noted in the left eye. There was no sign of any penetrating ocular trauma, and it was assumed that the posterior segment findings were primary injuries caused by the blast wave itself. Following anti-inflammatory treatment, partial vision was restored in the right eye. Surgical re-attachment of the retina was discussed and declined by the owner. This report describes, for the first time, vitreal hemorrhage and retinal detachment as the sole injuries caused by an explosive blast wave.

Abstract
The risk of massive exposure to toxic chemical substances including chemical weapons or industrial chemicals has increased especially during the last century due to the development in industry and chemistry science. This paper aims to describe a real chemical release event and further exposures to personnel working at the Esenboğa Airport, Ankara, Turkey, and to give lessons learned. This chemical release was noticed firstly by airport staff giving symptoms including nausea, vomiting, irritation of eyes, itching and rinorrhea. First responders from civil defense unit and a group of health staff including NBC First-aid and Rescue Team gave response to the incident. The increasing number of exposed or suspected cases transferred to hospital were isolated in Emergency Department (ED) following the decontamination at the airport. Due to the characteristic odour and the growing number of the victims, the releasing agent was considered to be likely cyanide or sulfur mustard. Because of the panic amongst the workers, the number of the exposed (real or suspected) people increased up to about 40 and were kept under observation in ED of the hospital. The chromotographic analysis revealed that the agent contained diallyl disulfide, an organo-sulfur compound present at very high concentrations in pure garlic oil. Blood results showed no cyanide and the isolation were terminated. Along with the lessons learned, incident showed that the health facilities should be prepared against such deliberate or accidental mass casualties.

Abstract
Primary care physicians are rarely mentioned in medical disaster plans. We describe how a group of mostly family physicians and administrators of the JPS Health Network (JPS) took primary responsibility for 3,700 evacuees of Hurricane Katrina who came to Tarrant County, Texas. JPS provided medical care to 1,664 (45%) evacuees during a 2-week period. The most common needs were medications for chronic illnesses and treatment of skin infections (primarily on the feet). The JPS Emergency Department saw only 148 evacuees, most of whom arrived by their own transportation and were not seriously ill. JPS created a triage center located several miles from the hospital that referred almost all evacuees with health care needs to a primary care clinic. It was an effective approach for caring for the medical needs of disaster victims and prevented an emergency department and hospital from being overwhelmed. The JPS experience may guide future planning efforts for natural or manmade disasters, especially pandemic threats.

Abstract
Injuries from explosions are multilayered. Although blast injuries are thought of most often in a military context, all nurses need to be prepared to care for these casualties. Awareness of the multiple levels of injuries and the need to modify care based on the underlying pathology have reduced morbidity and mortality in patients who have complex and very critical injuries.
