Acute Renal Failure in Natural Disasters

Sudden-impact natural disasters such as earthquakes present a serious challenge to medical personnel in both developed and less developed countries. Crush syndrome with acute renal failure has been identified as a major medical complication that occurs among people whose limbs are trapped by heavy objects during natural disasters such as earthquakes or volcanic eruptions. Rescue and field medical teams should be trained to recognize and promptly treat the problems associated with prolonged limb compression and should carry the appropriate fluids and medications to treat the complications of traumatic rhabdomyolysis. Early, aggressive volume replacement followed by forced solute-alkaline diuresis therapy may protect the kidney against acute renal failure. Better epidemiologic knowledge of the specific disaster conditions that predispose traumatic rhabdomyolysis to develop is clearly essential for those who must determine when emergency dialysis services are required in response to injuries sustained during natural disasters. Disaster health care personnel involved with providing emergency acute renal care should have a basic familiarity with disaster epidemiology in order to determine whether a given event requires their intervention. This paper includes recommendations for improving medical planning, preparedness, and response to natural disasters that cause acute renal failure.

Acute kidney injury and ESRD management in austere environments

Current knowledge about managing acute kidney injury in disaster situations stems mostly from lessons learned while taking care of crush syndrome patients during major earthquakes. More recently, there has been a greater focus on emergency preparedness for ESRD management. Natural or man-made disasters create an "austere environment," wherein resources to administer standard of care are limited. Advance planning and timely coordinated intervention during disasters are paramount to administer effective therapies and save lives. This article reviews the presentation and management of disaster victims with acute kidney injury and those requiring renal replacement therapies. Major contributions of some key national and international organizations in the field of disaster nephrology are highlighted. The article intends to increase awareness about nephrology care of disaster victims, among nephrology and non-nephrology providers alike.     

Major Incident Hospital: Development of a Permanent Facility for Management of Incident Casualties

Abstract Introduction:   Preparation is essential to cope with the challenge of providing optimal care when there is a sudden, unexpected surge of casualties due to a disaster or major incident. By definition, the requirements of such cases exceed the standard care facilities of hospitals in qualitative or quantitative respects and interfere with the care of regular patients. To meet the growing demands to be prepared for disasters, a permanent facility to provide structured, prepared relief in such situations was developed. Methods:   A permanent but reserved Major Incident Hospital (MIH) has been developed through cooperation between a large academic medical institution, a trauma center, a military hospital, and the National Poison Information Centre (NVIC). The infrastructure, organization, support systems, training and systematic working methods of the MIH are designed to create order in a chaotic, unexpected situation and to optimize care and logistics in any possible scenario. Focus points are: patient flow and triage, registration, communication, evaluation and training. Research and the literature are used to identify characteristic pitfalls due to the chaos associated with and the unexpected nature of disasters, and to adapt our organization. Results:   At the MIH, the exceptional has become the core business, and preparation for disaster and large-scale emergency care is a daily occupation. An Emergency Response Protocol enables admittance to the normally dormant hospital of up to 100 (in exceptional cases even 300) patients after a start-up time of only 15 min. The Patient Barcode Registration System (PBR) with EAN codes guarantees quick and adequate registration of patient data in order to facilitate good medical coordination and follow-up during a major incident. Discussion:   The fact that the hospital is strictly reserved for this type of care guarantees availability and minimizes impact on normal care. When it is not being used during a major incident, there is time to address training and research. Collaboration with the NVIC and infrastructural adjustments enable us to not only care for patients with physical trauma, but also to provide centralized care of patients under quarantine conditions for, say, MRSA, SARS, smallpox, chemical or biological hazards. Triage plays an important role in medical disaster management and is therefore key to organization and infrastructure. Caps facilitate role distribution and recognizibility. The PBR resulted in more accurate registration and real-time availability of patient and group information. Infrastructure and a plan is not enough; training, research and evaluation are necessary to continuously work on disaster preparedness. Conclusion:   The MIH in Utrecht (Netherlands) is a globally unique facility that can provide immediate emergency care for multiple casualties under exceptional circumstances. Resulting from the cooperation between a large academic medical institution, a trauma center, a military hospital and the NVIC, the MIH offers not only a good and complete infrastructure but also the expertise required to provide large-scale emergency care during disasters and major incidents.     

An emergency medical system approach to disaster planning.

The increasing prevalence of terrorist attacks and natural disasters has mandated that more emphasis be placed on emergency disaster planning. The report focuses on the 1976 Courthouse bombing in Boston, which generated 20 casualties. Ambulance response by Boston's Emergency Medical Service system was made in 2.5 minutes and all victims were transported from the scene within 20 minutes. Successful management of this incident employed several important principles of disaster planning. These include the initial medical response, staging at the scene, and hospital notification. Additionally, the concept of triage as an integral part of disaster planning is explained with examples of the on-site medical stabilization and treatment of casualties. The importance of these concepts in practice and the necessity of close coordination of ambulance response and the responses of other emergency agencies, i.e., Police and Fire, were clearly demonstrated in the disaster which resulted from the Courthouse bombing.     

Medical management after indoor fires: a review

Fires involving mass burn casualties require extreme efforts and flexibility from the regular health care system. The café fire in Volendam, which occurred shortly after midnight on the first of January 2001, resulted in the worst indoor mass burns incident in Dutch history. During the extensive medical evaluation of this disaster, it became obvious that information on similar incidents is relatively scarce in the literature. This article systematically reviews the existing information in the medical literature on indoor fires and provides findings and knowledge used in the evaluation of the medical management after indoor fires and for future mass burn casualty preparedness, mitigation and response. METHODS: A literature review was undertaken for burn disasters with characteristics similar to the indoor Volendam fire disaster. In all fires, the following aspects were investigated: characteristics of the fire; the initial emergency response; triage and on-site treatment; primary and secondary distribution; hospital admission; severity of the sustained injuries and mortality. RESULTS: A total of nine similar indoor fires were selected. The number of people involved was reported in seven fires (range 137-6000). All reports provided the mortality rate (range 1.4% to over 50%). Data regarding the emergency response could be collected in half of the studies. On-scene triage was performed in five fires. The number of hospitals participating in the primary distribution ranged from 1 to 19. Except for the Volendam fire, all patients were primarily distributed to general hospitals. CONCLUSION: Characteristics of indoor fires, which are relevant for disaster preparedness, mitigation and response are not frequently reported in medical literature. The current articles on indoor fires, mainly report on numbers of casualties and the mortality. Limited data are available to provide insight in the characteristics of management and medical treatment and to come up with suggestions for improvement of future burn incidents management. The evaluation of disasters should be based on uniform methods and structured reports and effective record keeping is essential to achieve this.     

Verteilungsplanung von Verletzten beim MANV oder Katastrophenfall

Relevant changes have occurred in disaster management in Germany due to legal alterations and the introduction of the diagnosis-related groups (DRG) system. This has resulted in a reduction in bed capacities and an increase in bed utilization. In addition to the preclinical deployment strategy the provisional aspects of disaster medicine with the problem of the emergency service/hospital interface will be described. A suggestion for a solution for optimization of patient allocation in mass disasters or catastrophes will be demonstrated with the catastrophe network of the German Society for Trauma Surgery (DGU).     

Making difficult ethical decisions in patient care during natural disasters and other mass casualty events

OBJECTIVE: Recent experiences in the United States with unprecedented terrorist attacks (9/11) and a devastating natural disaster (Hurricane Katrina) have demonstrated that the medical care of mass casualties during such disasters poses ethical problems not normally experienced in civilian health care. It is important to 1) identify the unique ethical challenges facing physicians who feel an obligation to care for victims of such disasters and 2) develop a national consensus on ethical guidelines as a resource for ethical decision making in medical disaster relief. STUDY DESIGN: A survey of pertinent literature was performed to assess experience and opinions on the condition of medical care in terrorist attacks and natural disasters, the ethical challenges of disaster medical care, and the professional responsibilities and responsiveness in disasters. CONCLUSIONS: It is necessary to develop a national consensus on the ethical guidelines for physicians who care for patients, victims, and casualties of disasters, and to formulate a virtue-based, yet practical, ethical approach to medical care under such extreme conditions. An educational curriculum for medical students, residents, and practicing physicians is required to best prepare all physicians who might be called upon, in the future, to triage patients, allocate resources, and make difficult decisions about treatment priorities and comfort care. It is not appropriate to address these questions at the time of the disaster, but rather in advance, as part of the ethics education of the medical profession. Important issues for resolution include inpatient and casualty triage and prioritization, medical liability, altered standards of care, justice and equity, informed consent and patient autonomy, expanding scope of practice in disaster medicine, and the moral and ethical responsibilities of physicians to care for disaster victims.     

Katastrophenmedizin in der Bundesrepublik Deutschland

The worldwide increase in the number of natural disasters and the exacerbation of the situation with terrorist threats have meant that disaster relief has become increasingly important, in Germany as elsewhere. Since 9/11, various national warning institutes have been started up, while mass casualty incident treatment still has to be organized by the individual states. In the event of a disaster, hospitals will have a crucial function. Specific analyses have shown that mass medical emergency plans exist but the degree to which they can be implemented needs improvement. Based on the DGU trauma network, a national “disaster network” is planned in collaboration with the federal agency for civil defense and disaster relief (Bundesamt für Bevölkerungsschutz und Katastrophenhilfe, BBK), which should allocate treatment capacities of the member hospitals and ease their preparations for a major disasters.     

The role of patient flow and surge capacity for in-hospital response in mass casualty events

Mass casualty events make demands on emergency services and disaster control. However, optimized in- hospital response defines the quality of definitive care. Therefore, German federal law governs the role of hospitals in mass casualty incidents. In hospital casualty surge is depending on resources that have to be expanded with a practicable alarm plan. Thus, in-hospital mass casualty management planning is recommended to be organized by specialized persons. To minimise inhospital patient overflow casualty surge principles have to be implemented in both, pre-hospital and in-hospital disaster planning. World soccer championship 2006 facilitated the initiation of surge and damage control principles in in-hospital disaster planning strategies for German hospitals. The presented concept of strict control of in-hospital patient flow using surge principles minimises the risk of in-hospital breakdown and increases definitive hospital treatment capacity in mass casualty incidents.     

Preparing an orthopedic practice to survive a natural disaster: a retrospective analysis of rebuilding after Hurricane Katrina

In the aftermath of the biggest natural disaster to hit the United States, valuable lessons can be learned to prepare us for future disasters. Physicians and other care givers should become involved in every level of disaster management. Most emergency plans are focused on triaging patients; however, little attention is paid to the logistics in evacuating hospitals or maintaining operations without outside communications. The lack of coordination and the breakdown of traditional communication channels were the biggest hurdles to overcome on the road to recovery.     

Disasters and mass casualties: I. General principles of response and management

Disaster planning and response to a mass casualty incident pose unique demands on the medical community. Because they would be required to confront many casualties with bodily injury and surgical problems, surgeons in particular must become better educated in disaster management. Compared with routine practice, triage principles in disasters require an entirely different approach to evaluation and care and often run counter to training and ethical values. An effective response to disaster and mass casualty events should focus on an "all hazards" approach, defined as the ability to adapt and apply fundamental disaster management principles universally to any mass casualty incident, whether caused by people or nature. Organizational tools such as the Incident Command System and the Hospital Incident Command System help to effect a rapid and coordinated response to specific situations. The United States federal government, through the National Response Plan, has the responsibility to respond quickly and efficiently to catastrophic incidents and to ensure critical life-saving assistance. International medical surgical response teams are capable of providing medical, surgical, and intensive care services in austere environments anywhere in the world.     

Bushfire disaster burn casualty management: the Australian "Black Saturday" bushfire experience

Mass burn disasters are among the most difficult disasters to manage, with major burns requiring complex management in a multidisciplinary setting and specialist burns services having limited capacity to deal with large numbers of complex patients. There is a paucity of literature addressing health system responses to mass burn disasters resulting from wildfires, with the events of the "Black Saturday" disaster in the state of Victoria, Australia, able to provide a unique opportunity to draw lessons and increase awareness of key management issues arising in mass burn casualty disasters. The event comprised the worst natural disaster in the state's history and one of the worst wildfire disasters in world history, claiming 173 lives and costing more than AUD 4 billion. This article draws on the national burns disaster plan instituted, Australian Mass Casualty Burn Disaster Plan (AUSBURNPLAN), and details the management of mass burn cases through a systems-based perspective.     

Experience in the accident and emergency department of the Royal Victoria Hospital with patients from civil disturbances in Belfast 1969-1972, with a review of disasters in the United Kingdom 1951-1971

Within a period of 3 years the Royal Victoria Hospital, Belfast, had to use its disaster drill on 46 occasions. On attempting to find the number of disasters in the United Kingdom since the setting up of the National Health Service, records of 42 other disasters were found. Reports of these disasters were studied, the literature in British medical journals was read, and this with personal experience in the Royal Victoria Hospital is the basis of a discussion on disaster planning. Some recommendations are made.     

Recommendation for the management of crush victims in mass disasters

"Recommendations for the management of crush victims in mass disasters" aims to assist medics, paramedics and rescue team members who provide care during disasters. Development of the recommendations followed an explicit process of literature review and, also internet and face-to-face discussions. The chapters cover medical and logistic measures, to be taken both at the disaster field and in the hospitals, to cope with the problems created by a catastrophe. Recommendations were based on retrospective analyses and case reports on past disasters, and also expert judgment or opinion. Since there are no randomized controlled trials, no GRADE approach was used to develop the recommendations, and no strengths of recommendations or levels of evidence are provided.     

China Medical Team: Medical rescue for “4.25” Nepal earthquake

In recent years, global natural disasters have been frequent and resulted in great casualties and property loss. Since Wenchuan earthquake, the disaster emergency rescue system of China has obtained considerable development in various aspects including team construction, task scheduling, personnel training, facilities and equipments, logistics, etc. On April 25, 2015, an earthquake that measured 8.1 on the Richter scale attacked Nepal. Chinese government firstly organized a medical team, named China Medical Team, and sent it to the attacked region in Nepal to implement medical rescue. The medical team completed the rescue mission successfully and creatively based on their experiences.     

Personalplanung in der zentralen Notaufnahme

In recent years the number of interdisciplinary emergency departments (ED) at hospitals in Germany has increased. The model of decentralized first contact units for each medical discipline has been abandoned, last but not least due to economic considerations. While decentralized units could be staffed with personnel from each discipline there is much controversy surrounding the question of which kind of doctor is best suited for a centralized ED. The development of programs providing the necessary qualification for German ED physicians in the future by working groups of several specialties is still nascent and has not yet produced concrete results. However, even without these special training programs, the management of critically ill or severely injured patients in the ED is paramount. The smooth operation of centralized EDs is therefore important. Therefore, taking into account economical aspects, qualification and number of available personnel, this article introduces a staffing concept as a rational basis for an optimized patient management in centralized EDs in Germany. Taking the patient characteristics, the specific treatment modalities and the number of admissions to the ED into account, this paper will determine treatment time per patient and the necessary number of physicians, as well as an optimized staffing model for EDs.     

Panik bei Großschadensereignissen

One of the greatest challenges in emergency medicine and in particular for emergency staff are disasters with huge amounts of victims. A subsequent development of a panic is a rare, but non the less an extreme aggravation of this emergency situation. This paper describes the psychological and anthropological background of panic reactions and gives a summary of the current evidence in research. Following this, panic may be defined as a reaction based on an internal assessment, that the probability to influence one self’s survival in a life-threatening situation is close to zero. The possibilities and limitations of behavioral modifications according to strategies that are derived from cognitive and behavioral psychotherapy are discussed. It is crucial to early detect situations at risk and to correctly assess one’s abilities for intervention. Thus, concrete possibilities of panic prevention in disaster medicine are presented as well as a concept of tasks the person in charge should be aware of for the prevention and management of panic.     

Patiententriage in einer interdisziplinären zentralen Notaufnahme

Changed political and social structures lead to the fact that more and more patients chose to go directly to the hospital and — against political intentions — patients are admitted even earlier to a hospital. It is necessary to manage and canalize these quite inconstant patient streams to the satisfaction of patients and doctors outside the hospital on the one hand and profitably for the hospital on the other hand. Arbitrary patient triage is no longer up-to-date for reasons of medical quality and economic aspects. The presented model clarifies the management of emergency patients in an interdisciplinary emergency room in a maximum care facility as field-tested on 110,000 patients.     

Air Force disaster response: Haiti experience

After the devastating earthquake in Haiti, the United States Air Force deployed multiple medical units as part of the disaster response. Air Force Special Operations Command medical teams provided initial medical response and assisted in the organization of medical assets. A small portable expeditionary aeromedical rapid response team with the assistance of a mobile aeromedical staging facility team stabilized patients for flight and coordinated air evacuation to the United States. An expeditionary medical support hospital was set up and assisted in patient movement to and from the USNS Comfort hospital ship. These units were able to adapt to the unique circumstances in Haiti and provide great patient care. The lessons learned from these experiences may help the United States better respond to future disasters.
