The London attacks--preparedness: Terrorism and the medical response

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 Outdated communication equipment, overwhelmed communication services, failure due to damaged infrastructure by the terrorist attack itself, and lack of training were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 Malfunctioning of (outdated) telecommunication services, inadequate training in the use of communication devices, unfortunate damage of telecommunication network infrastructure were also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

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.

Blast Injuries by an Improvised Explosive Device in Japan: A Case Report

Blast injuries caused by an improvised explosive device (IED) are becoming more common in civilian settings. However, physicians may not be familiar with the treatment and management of blast-injured victims. To the best of our knowledge, this is the first case report of a blast injury caused by an IED in Japan. A 64-year-old man was admitted to our hospital's emergency department after sustaining a blast injury. His vital signs were stable, but he had multiple small wounds with embedded foreign bodies that were consistent with injuries sustained by IED victims. The patient was treated for his injuries and was moved to another hospital on day 37. Knowledge about blast injuries caused by IEDs and management strategies for mass casualties are both necessary.

Emergency and Disaster Preparedness at a Tertiary Medical City

OBJECTIVE

The aim of this study was to evaluate the readiness of a tertiary medical city's response to a disaster by assessing the hospital resources and knowledge, attitudes, practices, and familiarity of health care providers toward disaster and emergency preparedness.

METHODS

All KFMC (King Fahad Medical City) staff with > 1 year of clinical experience were eligible to participate in a cross-sectional study. Participants responded to the Emergency Preparedness Information Questionnaire (EPIQ), knowledge and practice questionnaires, and a disaster planning attitude checklist. Data about resources were collected using the hospital disaster preparedness self-assessment tool.

RESULTS

The overall mean knowledge score for disaster and emergency preparedness was 4.4 ± 1.1, and the mean overall familiarity score was 3.43 ± 0.97. Most participants knew that disaster drills (90.2%) and training (74.6%) are ongoing. Sixty-six (21.0%) agreed that KFMC is unlikely to experience a disaster. The highest and lowest EPIQ familiarity scores were for decontamination (83.0%) and accessing critical resources and reporting (64.3%), respectively. Most participants (99.4%) have access to work computers; however, only 53.0% used the Internet to access information on bioterrorism and/or emergency preparedness. The hospital is ready to respond in case of a disaster according to the used tool.

CONCLUSIONS

The participants' levels of knowledge, practices, and overall familiarity toward emergency and disaster preparedness were satisfactory; however, participant attitudes and familiarity with where and how to access critical resources in the event of an emergency or disaster situations require reinforcement.

Using the Haddon matrix to explore medical response strategies for terrorist subway bombings

BACKGROUND

Since the 1970s, terrorist bombings in subways have been frequently occurring worldwide. To cope with this threat and to provide medical response countermeasures, we analyzed the characteristics of subway bombing terrorist attacks and used the Haddon matrix to explore medical response strategies.

METHODS

First, we analyzed 111 subway bombings from 1970 to 2017 recorded in the Global Terrorism Database to provide a reference for the strategy exploration. Then, we convened an expert panel to use the Haddon matrix to explore the medical response strategies to subway bombings.

RESULTS

In recent decades, at least one bombing attack occurs every 3 years. Summarized by the Haddon matrix, the influencing factors of medical responses to conventional subway bombings include the adequacy of first-aid kits and the medical evacuation equipment, the traffic conditions affecting the evacuation, the continuity and stability of communication, as well as the factors exclusively attributed to dirty bomb attacks in subways, such as ionizing radiation protection capabilities, the structure of the radiation sickness treatment network based on the subway lines, and the disposal of radioactive sewage. These factors form the basis of the strategy discussion.

CONCLUSION

Since subway bombings are long-term threats, it is necessary to have proper medical response preparation. Based on the Haddon matrix, we explored the medical response strategies for terrorist subway bombings, especially dirty bomb attacks. Haddon matrix can help policymakers systematically find the most important factors, which makes the preparations of the response more efficient.

Virtual-world hospital simulation for real-world disaster response: Design and validation of a virtual reality simulator for mass casualty incident management

BACKGROUND

Mass casualty incidents are unfortunately becoming more common. The coordination of mass casualty incident response is highly complex. Currently available options for training, however, are limited by either lack of realism or prohibitive expense and by a lack of assessment tools. Virtual worlds represent a potentially cost-effective, immersive, and easily accessible platform for training and assessment. The aim of this study was to assess feasibility of a novel virtual-worlds-based system for assessment and training in major incident response.

METHODS

Clinical areas were modeled within a virtual, online hospital. A major incident, incorporating virtual casualties, allowed multiple clinicians to simultaneously respond with appropriate in-world management and transfer plans within limits of the hospital's available resources. Errors, delays, and completed actions were recorded, as well as Trauma-NOnTECHnical Skills (T-NOTECHS) score. Performance was compared between novice and expert clinician groups.

RESULTS

Twenty-one subjects participated in three simulations: pilot (n = 7), novice (n = 8), and expert groups (n = 6). The novices committed more critical events than the experts, 11 versus 3, p = 0.006; took longer to treat patients, 560 (299) seconds versus 339 (321) seconds, p = 0.026; and achieved poorer T-NOTECHS scores, 14 (2) versus 21.5 (3.7), p = 0.003, and technical skill, 2.29 (0.34) versus 3.96 (0.69), p = 0.001. One hundred percent of the subjects thought that the simulation was realistic and superior to existing training options.

CONCLUSION

A virtual-worlds-based model for the training and assessment of major incident response has been designed and validated. The advantages of customizability, reproducibility, and recordability combined with the low cost of implementation suggest that this potentially represents a powerful adjunct to existing training methods and may be applicable to further areas of surgery as well.

Tactical and operational response to major incidents: feasibility and reliability of skills assessment using novel virtual environments

OBJECTIVES

To determine feasibility and reliability of skills assessment in a multi-agency, triple-site major incident response exercise carried out in a virtual world environment.

METHODS

Skills assessment was carried out across three scenarios. The pre-hospital scenario required paramedics to triage and treat casualties at the site of an explosion. Technical skills assessment forms were developed using training syllabus competencies and national guidelines identified by pre-hospital response experts. Non-technical skills were assessed using a seven-point scale previously developed for use by pre-hospital paramedics. The two in-hospital scenarios, focusing on a trauma team leader and a silver/clinical major incident co-ordinator, utilised the validated Trauma-NOTECHS scale to assess five domains of performance. Technical competencies were assessed using an ATLS-style competency scale for the trauma scenario. For the silver scenario, the assessment document was developed using competencies described from a similar role description in a real-life hospital major incident plan. The technical and non-technical performance of all participants was assessed live by two experts in each of the three scenarios and inter-assessor reliability was computed. Participants also self-assessed their performance using identical proformas immediately after the scenarios were completed. Self and expert assessments were correlated (assessment cross-validation).

RESULTS

Twenty-three participants underwent all scenarios and assessments. Performance assessments were feasible for both experts as well as the participants. Non-technical performance was generally scored higher than technical performance. Very good inter-rater reliability was obtained between expert raters across all scenarios and both technical and non-technical aspects of performance (reliability range 0.59-0.90, Ps<0.01). Significant positive correlations were found between self and expert assessment in technical skills across all three scenarios (correlation range 0.52-0.84, Ps<0.05), although no such correlations were observed in non-technical skills.

CONCLUSIONS

This study establishes feasibility and reliability of virtual environment technical and non-technical skills assessment in major incident scenarios for the first time. The development for further scenarios and validated assessment scales will enable major incident planners to utilise virtual technologies for improved major incident preparation and training.

Physical Health of Members of the Public Who Experienced Terrorist Bombings in London on 07 July 2005

Introduction:

On 07 July 2005, four bombs were detonated in London, killing 52 members of the public. Approximately 700 individuals received treatment either at the scene or at nearby hospitals.

Hypothesis/Problem:

Significant concerns about the potential long-term psychological and physical health effects of exposure to the explosions were raised immediately after the bombings. To address these concerns, a public health register was established for the purpose of following-up with individuals exposed to the explosions.

Methods:

Invitations to enroll in the register were sent to individuals exposed to the explosions. A range of health, emergency, and humanitarian service records relating to the response to the explosions were used to identify eligible individuals. Follow-up was undertaken through self-administered questionnaires. The number of patients exposed to fumes, smoke, dust, and who experienced blood splashes, individuals who reported injuries, and the type and duration of health symptoms were calculated. Odds ratios of health symptoms by exposure for greater or less than 30 minutes were calculated.

Results:

A total of 784 eligible individuals were identified, of whom, 258 (33%) agreed to participate in the register, and 173 (22%) returned completed questionnaires between 8 to 23 months after the explosions. The majority of individuals reported exposure to fumes, smoke, or dust, while more than two-fifths also reported exposure to blood. In addition to cuts and puncture wounds, the most frequent injury was ear damage. Most individuals experienced health symptoms for less than four weeks, with the exception of hearing problems, which lasted longer. Four-fifths of individuals felt that they had suffered emotional distress and half of them were receiving counseling.

Conclusions:

The results indicated that the main long-term health effects, apart from those associated with traumatic amputations, were hearing loss and psychological disorders. While these findings provide a degree of reassurance of the absence of long-term effects, the low response rate limits the extent to which this can be extrapolated to all those exposed to the bombings. Given the importance of immediate assessment of the range and type of exposure and injury in incidents such as the London bombings, and the difficulties in contacting individuals after the immediate response phase, there is need to develop better systems for identifying and enrolling exposed individuals into post-incident health monitoring.

Assessing Levels of Hospital Emergency Preparedness

Introduction:

Emergency preparedness can be defined by the preparedness pyramid, which identifies planning, infrastructure, knowledge and capabilities, and training as the major components of maintaining a high level of preparedness.The aim of this article is to review the characteristics of contingency plans for mass-casualty incidents (MCIs) and models for assessing the emergency preparedness of hospitals.

Characteristics of Contingency Plans:

Emergency preparedness should focus on community preparedness, a personnel augmentation plan, and communications and public policies for funding the emergency preparedness. The capability to cope with a MCI serves as a basis for preparedness for non-conventional events. Coping with chemical casualties necessitates decontamination of casualties, treating victims with acute stress reactions, expanding surge capacities of hospitals, and integrating knowledge through drills. Risk communication also is important.

Assessment of Emergency Preparedness:

An annual assessment of the emergency plan is required in order to assure emergency preparedness. Preparedness assessments should include: (1) elements of disaster planning; (2) emergency coordination; (3) communication; (4) training; (5) expansion of hospital surge capacity; (6) personnel; (7) availability of equipment; (8) stockpiles of medical supplies; and (9) expansion of laboratory capacities. The assessment program must be based on valid criteria that are measurable, reliable, and enable conclusions to be drawn. There are several assessment tools that can be used, including surveys, parameters, capabilities evaluation, and self-assessment tools.

Summary:

Healthcare systems are required to prepare an effective response model to cope with MCIs. Planning should be envisioned as a process rather than a production of a tangible product. Assuring emergency preparedness requires a structured methodology that will enable an objective assessment of the level of readiness.

Defining the Problem, Main Objective, and Strategies of Medical Management in Mass-Casualty Incidents Caused by Terrorist Events

Based on the experience of managing >20 such events during the last decade, the authors' understanding of a mass-casualty incident is that it is an event in which there may be many victims, but only a few that actually suffer from life-threatening injuries. To make an impact on survival, one must identify those who are severely wounded as quickly as possible and offer those patients opti-mal care. Experienced trauma physicians are the most important resource available to achieve this objective, and they should be allocated to the treat-ment of seriously injured victims instead of more traditional management roles such as triage and incident manager.

Burn Disasters—An Audit of the Literature

All events that result in disasters are unique, and it is impossible to become fully prepared. However, through thorough planning and preparedness, it is possible to gain a better understanding of the typical injury patterns and problems that arise from a variety of hazards. Such events have the potential to claim many lives and overwhelm local medical resources. Burn disasters vary in scope of injury and procedures required, and are much more labor and resource intensive than non-burn disasters.

This review of the literature should help determine whether, despite each event having its own unique features, there still are common problems disaster responders face in the prehospital and hospital phases, what recommendations were made from these disasters, and whether these recommendations have been implemented into practice and the current disaster planning processes.

The objective of this review was to assess: (1) prehospital and hospital responses used during past burn disasters; (2) problems faced during those disaster responses; (3) recommendations made following those disasters; (4) whether these recommendations were integrated into practice; and (5) the key characteristics of burn disasters and how they differ from other disasters. This review is important to determine why, despite having disaster plans, things still go wrong.

Characterization of the response to primary blast injury

Lung injuries, predominantly arising from blast exposure, are a clinical problem in a significant minority of current military casualties. This special feature consists of a series of articles on lung injury. This first article examines the mechanism of the response to blast lung (primary blast injury to the lung). Subsequent articles examine the incidence of blast lung, clinical consequences and current concepts of treatment, computer (in silico) modelling of lung injury and finally chemical injuries to the lungs. Blast lung is caused by a shock wave generated by an explosion causing widespread damage in the lungs, leading to intrapulmonary haemorrhage. This, and the ensuing inflammatory response in the lung, leads to a compromise in pulmonary gas exchange and hypoxia that can worsen over several hours. There is also a characteristic cardio-respiratory effect mediated via an autonomic reflex causing apnoea (or rapid shallow breathing), bradycardia and hypotension (the latter possibly also due to the release of nitric oxide). An understanding of this response, and the way it modifies other reflexes, can help the development of new treatment strategies for this condition and for the way it influences the patient's response to concomitant injuries.

Critical care management of major disasters: a practical guide to disaster preparation in the intensive care unit

Recent events and regulatory mandates have underlined the importance of medical planning and preparedness for catastrophic events. The purpose of this review is to provide a brief summary of current commonly identified threats, an overview of mass critical care management, and a discussion of resource allocation to provide the intensive care unit (ICU) director with a practical guide to help prepare and coordinate the activities of the multidisciplinary critical care team in the event of a disaster.

Preparedness lessons from modern disasters and wars

Disasters come in all shapes and forms, and in varying magnitudes and intensities. Nevertheless, they offer many of the same lessons for critical care practitioners and responders. Among these, the most important is that well thought out risk assessment and focused planning are vital. Such assessment and planning require proper training for providers to recognize and treat injury from disaster, while maintaining safety for themselves and others. This article discusses risk assessment and planning in the context of disasters. The article also elaborates on the progress toward the creation of portable, credible, sustainable, and sophisticated critical care outside the walls of an intensive care unit. Finally, the article summarizes yields from military-civilian collaboration in disaster planning and response.

Triage: Principles and Pressures

The aim of this paper is to review the art and science underpinning the application of effective triage. The paper also attempts to cut through the fog of confusion surrounding the topic and to point a way towards a generally-agreed unified approach. Triage needs to be understood in the context of the environment in which it is applied, and the paper deals with this in some detail.

Management and analysis of out-of-hospital health-related responses to simultaneous railway explosions in Madrid, Spain

OBJECTIVES

On 11 March 2004, 10 simultaneous explosions at four different locations of the rail network in Madrid caused 198 deaths and 2312 persons were injured. The aim of this manuscript is to describe the prehospital health-related activities from the Emergency Medical Service of Madrid and to analyze the responses, the major conclusions, and the lessons learned.

METHODS

Three meetings were held with professionals from the Emergency Medical Service of Madrid who were involved in the catastrophe. Two experts in quality management chaired the meetings. Detailed data were gathered on what occurred at the sites following the explosions. Additional data were gathered from professionals from the Coordination Service of Urgencies and from those who assisted relatives and friends of victims in the days following the bombings. All of the data were collected and were included in the final report.

RESULTS

We describe the activities carried out by the Coordination Service of Urgencies at each site immediately after the explosions and during the 11 days following the catastrophe. The successful performances and those that need to be improved at the four sites and elsewhere are detailed.

CONCLUSIONS

The main reasons for the 'positive responses' are the number of resources that acted, the professional abilities, and the flexibility of the services. The 'areas to be improved' are communications, the establishment of the top of the command at each site, and the organization of supplies for catastrophic assistance. From the analysis, we describe the main lessons learned and we present proposals for improvement, should a future catastrophe occur.

Developing disaster management modules: a collaborative approach

Disasters, whether natural or human induced, can strike when least expected. The events of 9/11 in the US, the 7/7 bombings in the UK, and the anthrax incident in the US on 10th October 2001 indicate that there is a need to have a nursing workforce who is able to respond effectively to mass casualty events and incidents involving chemical, biological, radiological and nuclear substances. Multi-agency collaboration is one of the fundamental principles of disaster preparedness and response. It was therefore necessary to take a similar multi-agency collaborative approach to develop modules on the management of mass casualty events and incidents involving hazardous substances. The modules are offered to registered nurses and registered paramedics. They can be taken independently or as part of a BSc in nursing or health pathway, on a part-time basis. Since the commencement of the modules in September 2004, registered paramedics and registered nurses who work in a wide range of specialties have accessed them.

Multiple casualty incidents: the prehospital role of the anesthesiologist in Europe

The recent increase in incidents involving mass casualties has emphasized the need for a planned and coordinated prehospital emergency medical response, with medical teams on-site to provide advanced trauma life support. The special skills of the anesthesiologist make his/her contribution to prehospital emergency care particularly valuable. The United Kingdom's emergency medical services system is operated paramedically like that in the United States, and is based on rapid evacuation of casualties to hospital emergency medical facilities. In contrast, the French approach is based on the use of its emergency care system SAMU, where both structured dispatching and on-site medical care is provided by physicians, including anesthesiologists. In this article, the lessons learned from multiple casualty incidents in Europe during the past 2 decades are considered from the standpoint of the anesthesiologist.

Cerebrovascular resuscitation after polytrauma and fluid restriction

BACKGROUND

There are few reproducible models of blast injury, so it is difficult to evaluate new or existing therapies. We developed a clinically relevant polytrauma model to test the hypothesis that cerebrovascular resuscitation is optimized when intravenous fluid is restricted.

STUDY DESIGN

Anesthetized swine (42+/-5 kg, n=35) received blasts to the head and bilateral chests with captive bolt guns, followed by hypoventilation (4 breaths/min; FiO(2)=0.21). After 30 minutes, resuscitation was divided into phases to simulate typical prehospital, emergency room, and ICU care. For 30 to 45 minutes, group 1, the control group (n=5), received 1L of normal saline (NS). For 45 to 120 minutes, additional NS was titrated to mean arterial pressure (MAP) > 60 mmHg. After 120 minutes, mannitol (1g/kg) and phenylephrine were administered to manage cerebral perfusion pressure (CPP) > 70 mmHg, plus additional NS was given to maintain central venous pressure (CVP) > 12 mmHg. In group 2 (n=5), MAP and CPP targets were the same, but the CVP target was>8 mmHg. Group 3 (n=5) received 1 L of NS followed only by CPP management. Group 4 (n=5) received Hextend (Abbott Laboratories), instead of NS, to the same MAP and CPP targets as group 2.

RESULTS

Polytrauma caused 13 deaths in the 35 animals. In survivors, at 30 minutes, MAP was 60 to 65 mmHg, heart rate was >100 beats/min, PaO(2) was < 50 mmHg, and lactate was>5 mmol/L. In two experiments, no fluid or pressor was administered; the tachycardia and hypotension persisted. The first liter of intravenous fluid partially corrected these variables, and also partially corrected mixed venous O(2), gastric and portal venous O(2), cardiac output, renal blood flow, and urine output. Additional NS (total of 36+/-1 mL/kg/h and 17+/-6 mL/kg/h, in groups 1 and 2, respectively) correlated with increased intracranial pressure to 38+/-4 mmHg (group 1) and 26+/-4 mmHg (group 2) versus 22+/-4 mmHg in group 3 (who received 5+/-1 mL/kg/h). CPP was maintained only after mannitol and phenylephrine. By 5 hours, brain tissue PO(2) was>20 mmHg in groups 1 and 2, but only 6+/-1 mmHg in group 3. In contrast, minimal Hextend (6+/-3 mL/kg/h) was needed; the corrections in MAP and CPP were immediate and sustained, intracranial pressure was lower (14+/-2 mmHg), and brain tissue PO(2) was> 20 mmHg. Neuropathologic changes were consistent with traumatic brain injury, but there were no statistically significant differences between groups.

CONCLUSIONS

After polytrauma and resuscitation to standard MAP and CPP targets with mannitol and pressor therapy, we concluded that intracranial hypertension was attenuated and brain oxygenation was maintained with intravenous fluid restriction; cerebrovascular resuscitation was optimized with Hextend versus NS; and longer term studies are needed to determine neuropathologic consequences.

Caring for a surge of Hurricane Katrina evacuees in primary care clinics

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.

Disaster preparedness, triage, and surge capacity for hospital definitive care areas: optimizing outcomes when demands exceed resources

Disaster planning must anticipate how demands imposed by a disaster reconcile with the capacity of the treating facility. Resources must be organized before an event so that they are optimally used to treat as many victims as possible, as well as to avoid overwhelming available resources.

Do Trauma Centers Have the Capacity to Respond to Disasters?

BACKGROUND

Concern has been raised about the capacity of trauma centers to absorb large numbers of additional patients from mass casualty events. Our objective was to examine the capacity of current centers to handle an increased load from a mass casualty disaster.

METHODS

This was a cross-sectional study of Level I and II trauma centers. They were contacted by mail and asked to respond to questions about their surge capacity as of July 4, 2005.

RESULTS

Data were obtained from 133 centers. On July 4, 2005 there were a median of 77 beds available in Level I and 84 in Level II trauma centers. Fifteen percent of the Level I and 12.2% of the Level II centers had a census at 95% capacity or greater. In the first 6 hours, each Level I center would be able to operate on 38 patients, while each Level II center would be able to operate on 22 patients. Based on available data, there are 10 trauma centers available to an average American within 60 minutes. Given the available bed capacity, a total of 812 beds would be available within a 60-minute transport distance in a mass casualty event.

CONCLUSIONS

There is capacity to care for the number of serious non-fatally injured patients resulting from the types of mass casualties recently experienced. If there is a further continued shift of uninsured patients to and fiscally driven closure of trauma centers, the surge capacity could be severely compromised.

Predictors of mortality in close proximity blast injuries during Operation Iraqi Freedom

BACKGROUND

Blast injury is an increasingly common problem faced by military surgeons in the field. Because of urban terrorism worldwide, blast injury is becoming more common in the civilian sector as well. Blast injuries are often devastating and can overwhelm medical resources. We sought to determine whether simple factors easily obtained from the clinical history and primary survey could be used to triage patients more effectively.

STUDY DESIGN

A retrospective review of 18 consecutive close-proximity blast injury patients presenting to a forward deployed surgical unit in Iraq was performed. Patients' injuries and outcomes were recorded. We compared the presence of sustained hypotension, penetrating head injury, multiple (three or more) long-bone fractures, and associated fatalities (whether another patient involved in the same explosion died) between nonsurvivors and survivors using Fisher's exact test.

RESULTS

All patients who presented alive but exhibited sustained hypotension (n = 5) died, versus 0% who did not exhibit sustained hypotension (n = 9, p < 0.01). There was no marked increase in mortality with presence of multiple long-bone fractures, penetrating head injury, or associated fatalities individually. Having two or more of these factors was associated with a mortality of 86% (6 of 7) versus 20% (2 of 10, p = 0.015) in those who had less than two factors.

CONCLUSIONS

Blast injury can overwhelm military and civilian trauma systems alike. Sustained hypotension and presence of two or more easily determined factors, including three or more long-bone fractures, penetrating head injury, and associated fatalities, are associated with increased mortality and can potentially help triage patients and allocate scarce resources more efficiently.

Terrorist attacks: learning from the past and planning for the future

Terrorist bomb attacks on the UK mainland are not a new phenomenon. However, since the IRA ceasefire, such incidents have been relatively few. Unlike IRA bombings, which generally targeted commercial property or military personnel and were often preceded by warning phone calls, the attacks in London and Madrid deliberately targeted civilians with no warning. The detonation of devices at multiple sites and in densely packed, enclosed areas was intended to maximize the number of fatalities and inflict severe injuries on survivors. Indiscriminate outrages such as those perpetrated in London on 7 July are unlikely to be ‘one offs’ and may be repeated in the near future.
