Complex humanitarian emergencies: a review of epidemiological and response models.

Complex emergencies (CEs) have been the most common human-generated disaster of the past two decades. These internal conflicts and associated acts of genocide have been poorly understood and poorly managed. This article provides an epidemiological background and understanding of developing and developed countries, and chronic or smoldering countries' CEs, and explains in detail the prevailing models of response seen by the international community. Even though CEs are declining in number, they have become more complex and dangerous. The UN Charter reform is expected to address internal conflicts and genocide but may not provide a more effective and efficient means to respond.

Military assistance in complex emergencies: what have we learned since the Kurdish relief effort?

After the success of relief efforts to the displaced Kurdish population in northern Iraq following the Gulf War, many in the US military and the international relief community saw military forces as critical partners in the response to future complex emergencies (CEs). However, successes in subsequent military involvement in Somalia, Rwanda, the former Yugoslavia, and other CEs proved more elusive and raised many difficult issues. A review of these operations reinforces some basic lessons that must be heeded if the use of military forces in humanitarian relief is to be successful. Each CE is unique, thus, each military mission must be clearly defined and articulated. Armed forces struggle to provide both security and humanitarian relief, particularly when aggressive peace enforcement is required. Significant political and public support is necessary for military involvement and success. Military forces cannot execute humanitarian assistance missions on an ad hoc basis, but must continue to develop doctrine, policy and procedures in this area and adequately train, supply, and equip the units that will be involved in humanitarian relief. Militaries not only must cooperate and coordinate extensively with each other, but also with the governmental and non-governmental humanitarian relief organizations that will be engaged for the long term.

Infant feeding practices in complex emergencies: a case study approach.

The majority of deaths associated with complex emergencies are attributed to infants and children under the age of five years. Most of these deaths are related to preventable diseases such as malnutrition, diarrhea, and malaria. Infant feeding emergencies have emerged as a major factor in complex emergencies. This paper reviews the current information relative to infant feeding, and uses four case studies as educational tools for the management of infant feeding emergencies. Child mortality rates in refugee population have been linked directly to protein-energy malnutrition (PEM). Breast feeding has many advantages over all other forms of feeding for children up to the age of two years of age. These advantages are discussed in detail in this paper. In addition, the appropriate and inappropriate uses of breast-milk substitutes (BMS) are discussed. Breast feeding also may play a role in the spread of HIV infections from the mother to the infant. However, in the setting of complex emergencies in the developing world, the risk of an infant dying of malnutrition and infection when not breastfed is likely to be greater than is the risk of death due to HIV acquisition through breastfeeding. The physiology of lactation is reviewed with particular reference to the roles of prolactin, oxytocin, and the feedback inhibitor of lactation (FIL) hormone. No medications have been demonstrated to augment milk production that can be used in a practical sense in complex emergencies. Lastly, the principles promulgated by the WHO and UNHCR for the feeding of infants and children in emergencies and for milk powder distribution are summarized.

The concept of assisted management of large-scale disasters by horizontal organizations.

Management of large-scale disasters is impeded by inadequately designed organizational infrastructure. The vertical organizational structures of most agencies responding to disasters contribute to a poorly integrated response, especially when collaboration, information sharing, and coordination are required. Horizontal (or lateral) organizations have assisted traditionally vertical civilian and military agencies by enhancing their capacity to operate successfully in complex human emergencies and large-scale natural disasters. Because of the multiagency and highly technical multidisciplinary requirements for decision-making in chemical and biological disasters, similar horizontal management options must be considered.

Medical relief personnel in complex emergencies: perceptions of effectiveness in the former Yugoslavia.

Humanitarian medical assistance and intervention during the civil war in Bosnia and Croatia was felt by national health workers to be relatively ineffective (2.8 on a 5-point Likert scale), compared to other forms of humanitarian assistance such as medical supplies (4.4/5) and non-medical materials (3.9/5). Bosnian physicians treating civilians noted that the most helpful types of personnel were surgeons and emergency physicians. This study suggests that assessment of personnel needs at the recipient level, in addition to standard relief assessments, is required early in models of complex emergencies. This study supports existing epidemiological models of complex emergencies, especially when high trauma-related mortality and morbidity are likely to occur.

Developing public health indicators in complex emergency response.

During the past decade, indicators for the assessment, monitoring, and evaluation of services provided by humanitarian organizations to populations affected by complex emergencies (CEs) were developed to improve the effectiveness and accountability of humanitarian response. The quality of data used to develop individual indicators and their relationship to positive health outcomes varies greatly. This article states the essential characteristics necessary for the development and implementation of effective indicators in CE response and proposes the establishment of an evidence-based grading system. The importance of trend analysis and the modification or addition of various indicators and their thresholds, according to phase and location of CEs, are stressed. Limitations in the development, implementation, and interpretation of these indicators, including those outside of the organizations' control are discussed. More evidence-based research is needed as to the type and thresholds of indicators that lead to improved health outcomes in populations affected by CEs. The use of indicators by non-governmental organizations, and how they affect their program's decision-making in different phases and settings within CEs need further study. Finally, the establishment of a regulating body with the authority to enforce the attainment of standards by use of these indicators is necessary to avoid inappropriate humanitarian assistance causing loss of life in the future.

Telecommunications systems in support of disaster medicine: applications of basic information pathways.

Disaster events have always been a fact of life. Success or failure of a disaster response is often determined by timely access to communication and reliable information. The rapid progress and future course in telecommunications indicate that lack of communications need no longer be the paralyzing factor in a disaster scenario. This is especially important for medical response where time is of essence to save lives. This article explores various telecommunications tools that can enhance medical response in a disaster and includes those associated with telemedicine (providing medical care from a distance through telecommunications). Disaster telemedicine systems need not be special or sophisticated-the challenge is to match the right systems with a given disaster plan or scenario. A brief history of telemedicine use for disaster relief and humanitarian assistance is presented together with a discussion of advantages, disadvantages, and near-future potential of telecommunication systems to gain a better perspective of which tools might best fit disaster medicine needs today and into the new millennium.

Applications of telemedicine and telecommunications to disaster medicine: historical and future perspectives.

Disaster management utilizes diverse technologies to accomplish a complex set of tasks. Despite a decade of experience, few published reports have reviewed application of telemedicine (clinical care at a distance enabled by telecommunication) in disaster situations. Appropriate new telemedicine applications can improve future disaster medicine outcomes, based on lessons learned from a decade of civilian and military disaster (wide-area) telemedicine deployments. This manuscript reviews the history of telemedicine activities in actual disasters and similar scenarios as well as ongoing telemedicine innovations that may be applicable to disaster situations. Emergency care providers must begin to plan effectively to utilize disaster-specific telemedicine applications to improve future outcomes.

Emergency Medical Services System in Hong Kong: a pearl in the South China Sea.

Each Emergency Medical Services (EMS) system is unique in its development and scope of practice. In many instances, it incorporates components of other models. It is important to the intellectual growth of the Emergency Medical Technicians that they visualize EMS design from an international perspective. This article describes the EMS system that exists in Hong Kong. It explores the changes that are occurring, defines the relationship between Hong Kong and China, and considers the influence that this evolving model might have on China after 1997.

Constructing a World Wide Web site for disaster management and humanitarian assistance.

There is a huge need for access to information in the areas of disaster relief, disaster medicine, and humanitarian assistance. The extraordinarily rapid increase in the literature in these subject areas attests to this need. However, use of the printed word has substantial limitations that are even more profound in the developing world. Currently, the information available tends to be fragmented and sequestered by the specific interests of the organizations and governments involved. The evolving electronic methods for the storage, organization, and retrieval of information makes coordination between organizations concerned with disasters within our grasp. This paper discusses the Center of Excellence in Disaster Management and Humanitarian Assistance and describes the World Wide Web and the implications it has in disaster management and medicine. It describes methods for obtaining user input to the techniques used for the development of the world wide web for the areas of disaster management and disaster medicine. The implementation of an on-line Internet reference desk that will provide: 1) a list of "experts;" 2) a searchable disaster database; and 3) on-line simulation courses and training exercises also is discussed.

Strategic disaster preparedness and response: implications for military medicine under joint command.

With the end of the Cold War, renewed emphasis has been placed on humanitarian assistance such as disaster relief, refugee management, and humanitarian intervention during conflicts by the military forces of all nations. The role of the military in humanitarian assistance has been the subject of much recent debate, as the ability of the United States to mount an effective emergency response is linked to our nation's strategic policy and planning. This article describes and broadens the understanding of the evolving concepts of strategic disaster management and the role of Joint Military Commands in providing disaster relief. Examples of strategic humanitarian relief operations are discussed.

Health care personnel in disaster response. Reversible roles or territorial imperatives?

Disasters frequently demand exceptional skills from medical responders. Providers work most efficiently and effectively, however, within the roles and hierarchical structures with which they are familiar. The goal of disaster medical response planners is to assign personnel to roles that are as familiar as possible and to simultaneously enhance flexibility of response to extraordinary circumstances. We have outlined the most common disaster medical response roles and the personnel types that fit most directly as a primary provider within each role. Medics excel in field operations and field care of patients, whereas the training of nurses and physicians makes them the most flexible all-around providers, if specially trained in field emergency care, and the sole providers of definitive care. None of the providers, by virtue of their basic training, is well equipped to manage the public health consequences of disasters, but nurses and physicians should be able to easily move into the role, given appropriate special training. Some of the special courses needed to make medics, nurses, and physicians capable of serving flexible roles already exist; others need to be developed or enhanced.

Infectious disease emergencies in disasters.

This article discusses the relationship between disasters and infections. Infections that are reviewed include those resulting from (1) a breakdown of the usual mechanisms of infection control, (2) the introduction or emergence of pathogens, and (3) the movement of populations into new areas. Components of infectious-disease surveillance and disaster teams are detailed.
