The public health dimension of disasters--health outcome assessment of disasters

A broad range of health problems are related to disasters. Insight into these health problems is needed for targeted disaster management. Disaster health outcome assessment can provide insight into the health effects of disasters. During the 15th World Congress on Disaster and Emergency Medicine in Amsterdam (2007), experts in the field of disaster epidemiology discussed important aspects of disaster health outcome assessment, such as: (1) what is meant by disaster health outcome assessment?; (2) why should one conduct a disaster health outcome assessment, and what are the objectives?, and (3) who benefits from the information obtained by a disaster health outcome assessment? A disaster health outcome assessment can be defined as a systematic assessment of the current and potential health problems in a population affected by a disaster. Different methods can be used to examine these health problems such as: (1) rapid assessment of health needs; (2) (longitudinal) epidemiological studies using questionnaires; (3) continuous surveillance of health problems using existing registration systems; (4) assessment of the use and distribution of health services; and (5) research into the etiology of the health effects of disasters. The public health impact of a disaster may not be immediately evident. Disaster health outcome assessment provides insight into the health related consequences of disasters. The information that is obtained by performing a disaster health outcome assessment can be used to initiate and adapt the provision of health care. Besides information for policymakers, disaster health outcome assessments can contribute to the knowledge and evidence base of disaster health outcomes (scientific objective). Finally, disaster health outcome assessment might serve as a signal of recognition of the problems of the survivors. Several stakeholders may benefit from the information obtained from a disaster health outcome assessment. Disaster decision-makers and the public health community benefit from performing a disaster health outcome assessment, since it provides information that is useful for the different aspects of disaster management. Also, by providing information about the nature, prevalence, and course of health problems, (mental) health care workers can anticipate the health needs and requirements in the affected population. It is important to realize that the disaster is not over when the acute care has been provided. Instead, disasters will cause many other health problems and concerns such as infectious diseases and mental health problems. Disaster health outcome assessments provide insight into the public health impact of disasters.     

Lessons public health professionals learned from past disasters

ABSTRACT Objectives: Delineate the lessons that public health professionals learned during past disasters and information/resources found to be lacking during past disasters.
Design/sample: Qualitative research consisting of 32 participants who attended the 2006 Association for Professionals in Infection Control and Epidemiology Conference and participated in 1 of 3 focus groups.
Measurements: Focus group sessions were audiotaped; tapes were transcribed verbatim. Content analysis included identifying, coding, and categorizing participants' responses. Major themes were identified and categorized.
Results: Disasters can result in public health crises if infection prevention/control interventions are not implemented rapidly and appropriately. Gaps in past public health disaster response include infection prevention/control in mass casualty incidents, public education, internal and external communication, mental health, physical plant, and partnerships with outside agencies. Participants emphasized the need to provide consistent messages to the public, communicate between agencies, and provide public education on disaster preparedness. These tasks can be challenging during infectious disease emergencies when recommendations change. Effective communication is necessary to maintain public trust. Infection control issues in shelters, such as hand hygiene products/facilities, sanitation, outbreaks of unusual infectious diseases, overcrowded conditions, and poor environmental decontamination, were identified as critical to prevent secondary disease transmission.
Conclusion: Public health and infection control nurses must partner and continue to address gaps in disaster planning.     

How to talk to the media: televised coverage of public health issues in a disaster

Public health officials often are critical of the way television news covers disasters, while broadcast journalists complain of a lack of cooperation from the public health sector during disaster coverage. This article summarizes the issues discussed in a session on Televised Coverage of Disasters, presented in April 1999 at the UCLA Conference on Public Health and Disasters in Los Angeles. Public health officials were asked to "talk back to their television sets" in a dialog with television journalists. Concerns included: 1) the lack of balance in television coverage that is dominated by sensational images that may frighten rather than inform the public; 2) the potential for psychological damage to viewers when frightening images are shown repeatedly in the days and weeks of the disaster; and 3) the perception that TV reporters place too much emphasis on crime, property damage, and loss of life, giving relatively low priority to disaster preparedness and to public health issues in the aftermath of a disaster. Options for improving communication between television journalists and public health professionals also are discussed.     

Public health nursing competencies for public health surge events

OBJECTIVE: To develop consensus regarding public health nursing competencies in the event of a public health surge event related to disaster. DESIGN AND METHODS: Using a 3-round Delphi approach, public health nurses (PHNs) and directors of nursing from local health departments, state nursing leaders, and national nursing preparedness experts reviewed and commented on 49 draft competencies derived from existing documents. RESULTS: The final 25 competencies were categorized into Preparedness (n=9), Response (n=8), and Recovery (n=7). The Preparedness competencies focus on personal preparedness; comprehending disaster preparedness terms, concepts, and roles; becoming familiar with the health department's disaster plan, communication equipment suitable for disaster situations; and the role of the PHN in a surge event. Conducting a rapid needs assessment, outbreak investigation and surveillance, public health triage, risk communication, and technical skills such as mass dispensing are Response phase competencies. Recovery competencies include participating in the debriefing process, contributing to disaster plan modifications, and coordinating efforts to address the psychosocial and public health impact of the event. CONCLUSIONS: Identification of competencies for surge events that are specific to public health nursing is critical to assure that PHNs are able to respond to these events in an effective and efficient manner.     

Integration of disaster mental health services with emergency medicine

Despite limited resources, emergency medical settings will be called upon to play many roles in the context of disasters and terrorist attacks that are related to preparedness, surveillance, mental health services delivery, and staff care. Such settings are a central capture site for those individuals likely to be at highest risk for developing mental health and functional problems. Because much of the potential harm to survivors of disaster or terrorism (and their families) will be related to their mental health and role functioning, preparedness requires the active integration of behavioral health into emergency medicine in every component of disaster response. There are many challenges of doing this including: (1) finding ways to integrate activities of the medical care, emergency response, and public health systems; (2) determining whether an incident has actually occurred; (3) making differential diagnoses and managing other aspects of initial medical needs; and (4) coping with the risks associated with system overload and failure. Delivery of direct mental health care must include: (1) survivor and family education; (2) identification and referral of those requiring immediate care and follow-up; (3) group education and support services; and (4) individual counseling. In order for effective response to occur, the integration of psychosocial care into disaster response must occur prior to the disaster itself, and will depend on effective collaboration between medical and mental health care providers. At workplaces, emergency medical care centers must ensure that staff and their families are properly trained and supported with regard to their disaster functions and encouraged to develop personal/family disaster plans.     

Information technology and public health management of disasters--a model for South Asian countries

This paper highlights the use of information technology (IT) in disaster management and public health management of disasters. Effective health response to disasters will depend on three important lines of action: (1) disaster preparedness; (2) emergency relief; and (3) management of disasters. This is facilitated by the presence of modern communication and space technology, especially the Internet and remote sensing satellites. This has made the use of databases, knowledge bases, geographic information systems (GIS), management information systems (MIS), information transfer, and online connectivity possible in the area of disaster management and medicine. This paper suggests a conceptual model called, "The Model for Public Health Management of Disasters for South Asia". This Model visualizes the use of IT in the public health management of disasters by setting up the Health and Disaster Information Network and Internet Community Centers, which will facilitate cooperation among all those in the areas of disaster management and emergency medicine. The suggested infrastructure would benefit the governments, non-government organizations, and institutions working in the areas of disaster and emergency medicine, professionals, the community, and all others associated with disaster management and emergency medicine. The creation of such an infrastructure will enable the rapid transfer of information, data, knowledge, and online connectivity from top officials to the grassroots organizations, and also among these countries regionally. This Model may be debated, modified, and tested further in the field to suit the national and local conditions. It is hoped that this exercise will result in a viable and practical model for use in public health management of disasters by South Asian countries.     

Public health preparedness for mass-casualty events: a 2002 state-by-state assessment

INTRODUCTION: The ongoing threat of a terrorist attack places public agencies under increasing pressure to ensure readiness in the event of a disaster. Yet, little published information exists regarding the current state of readiness, which would allow local and regional organizations to develop disaster preparedness plans that would function seamlessly across service areas. The objective of this study is to characterize state-level disaster readiness soon after September 2001 and correlate readiness with existing programs providing an organized response to medical emergencies. METHODS: During the first quarter of 2002, a cross-sectional survey assessing five components of disaster readiness was administered in all 50 states. The five components of disaster readiness included: (1) statewide disaster planning; (2) coordination; (3) training; (4) resource capacity; and (5) preparedness for biological/chemical terrorism. RESULTS: Most states reported the presence of a statewide disaster plan (94%), but few are tested by activation (48%), and still fewer contain a bioterrorism component (38%). All states have designated disaster operations centers (100%), but few states have an operating communications system linking health and medical resources (36%). Approximately half of states offer disaster training to medical professionals; about 10% of states require the training. Between 22-48% of states have various contingency plans to treat victims when service capacity is exceeded. Biochemical protective equipment for health professionals is lacking in all but one state, and only 10% of states indicate that all hospitals have decontamination capabilities. States with a functioning statewide trauma system were significantly more likely to possess key attributes of a functioning disaster readiness plan. CONCLUSION: These findings suggest that disaster plans are prevalent among states. However, key programs and policies were noticeably absent. Communication systems remain fragmented and adequate training programs and protective equipment for health personnel are markedly lacking. Statewide trauma systems may provide a framework upon which to build future medical disaster readiness capacity.     

Policy development in disaster preparedness and management: lessons learned from the January 2001 earthquake in Gujarat, India

INTRODUCTION: During the last decades, several humanitarian emergencies have occurred, with an increasing number of humanitarian organizations taking part in providing assistance. However, need assessments, medical intelligence, and coordination of the aid often are sparse, resulting in the provision of ineffective and expensive assistance. When an earthquake with the strength of 7.7 on the Richter scale struck the state of Gujarat, India, during the early morning on 26 January 2001, nearly 20,000 persons were killed, nearly 170,000 were injured, and 600,000 were rendered homeless. This study identifies how assigned indicators to measure the level of health care may improve disaster preparedness and management, thus, reducing human suffering. METHODS: During a two-week mission in the disaster area, the disaster relief provided to the disaster-affected population of Gujarat was evaluated. Vulnerability due to climate, geography, culture, religion, gender, politics, and economy, as each affected the outcome, was studied. By assigning indicators to the eight ELEMENTS of the Primary Health Care System as advocated by the World Health Organization (WHO), the level of public health and healthcare services were estimated, an evaluation of the impact of the disaster was conducted, and possible methods for improving disaster management are suggested. Representatives of the major relief organizations involved were interviewed on their relief policies. Strategies to improve disaster relief, such as policy development in the different aspects of public health/primary health care, were sought. RESULTS: Evaluation of the pre-event status of the affected society revealed a complex situation in a vulnerable society with substantial deficiencies in the existing health system that added to the severity of the disaster. Most of the civilian hospitals had collapsed, and army field hospitals provided medical care to most of the patients under primitive conditions using tents. When the foreign field hospitals arrived five to seven days after the earthquake, most of the casualties requiring surgical intervention already had been operated on. Relief provided to the disaster victims had reduced quality for the following reasons: (1) proper public health indicators had not yet been developed; (2) efficient coordination was lacking, (3) insufficient, overestimated, or partly irrelevant relief was provided; (4) relief was delayed because of bureaucracy; and (5) policies on the delivery of disaster relief had not been developed. CONCLUSION: To optimize the effectiveness of limited resources, disaster preparedness and the provision of feasible and necessary aid is of utmost importance. An appropriate, rapid, crisis intervention could be achieved by continual surveillance of the world's situation by a Relief Coordination Center. A panel of experts could evaluate and coordinate the international disaster responses and make use of stored emergency material and emergency teams. A successful disaster response will depend on accurate and relevant medical intelligence and socio-geographical mapping in advance of, during, and after the event(s) causing the disaster. More effective and feasible equipment coordinated with the relief provided by the rest of the world is necessary. If policies and agreements are developed as part of disaster preparedness, on international, bilateral, and national levels, disaster relief may be more relevant, less chaotic, and easier to estimate, thus, bringing improved relief to the disaster victims.     

Disaster preparedness and response: Challenges for Australian public health nurses – A literature review

To date, Australia has not had to respond to a nationwide catastrophic event. However, over the past decade, heat waves, bushfires, cyclones, and floods have significantly challenged Australia's disaster preparedness and the surge capacity of local and regional health systems. Given that disaster events are predicted to increase in impact and frequency, the health workforce needs to be prepared for and able to respond effectively to a disaster. To be effective, nurses must be clear regarding their role in a disaster and be able to articulate the value and relevance of this role to communities and the professionals they work with. Since almost all disasters will exert some impact on public health, it is expedient to prepare the public health nursing workforce within Australia. This paper highlights issues currently facing disaster nursing and focuses on the challenges for Australian public health nurses responding to and preparing for disasters within Australia. The paper specifically addresses public health nurses' awareness regarding their roles in disaster preparation and response, given their unique skills and central position in public health.     

Earthquakes in El Salvador: a descriptive study of health concerns in a rural community and the clinical implications--part II.

Results reported in Part I of the Earthquakes in El Salvador series (see Disaster Management & Response 2003;1:105-9) indicated clinically relevant findings. The findings indicated a need for greater public health action within all five categories reviewed: healthcare, access to healthcare, housing, food, water and sanitation. Significant results between urban and rural communities indicated a need for broader community aid, public health and sanitation services to rural areas. Faster and more efficient disaster management and care services throughout the San Sebastian community were also necessary modifications.     

Partnering to prepare: An academic/workforce collaboration to develop disaster shelter training for nurses

In California, more frequent, intense, and destructive wildfires have prompted public health departments to enhance disaster response plans as evacuations and shelter needs increase. In addition, individuals utilizing shelters have increasingly complex medical and behavioral health needs and are accessing shelters for longer periods of time. Public health nurses (PHNs) are often called to staff disaster shelters but may have less recent experience in, or comfort with, direct patient care. Many health departments are experiencing challenges developing sustainable training infrastructure that prepares PHNs to deliver direct patient care in disaster shelters. Partnering with academic institutions can address this challenge. This article describes a partnership between a regional collaborative of health jurisdictions and a public university to train public health nurses to work in disaster shelters. The training demonstrates a sustainable way to instruct public health nurses while also highlighting the potential of partnerships between academic institutions and local health departments to address disaster preparedness and response needs in a community. Public health nurses are essential to public health preparedness and providing additional training can augment their ability to respond to disasters.     

Proceedings for the 5th Asia-Pacific Conference on Disaster Medicine: creating an agenda for action

Disaster medicine has come to the forefront and has become the focus of interest not only in the medical community, but also in the eyes of the public. The 5th APCDM was convened in Vancouver, Canada, 27-30 September 2000. It brought together over 300 delegates from 32 countries to share their experiences and thoughts regarding disaster events and how to effectively manage them. The conference was devoted to the task of establishing priorities and creating an Agenda for Action. From the discussions, key actions required were defined: COMMUNICATIONS: (1) Identify existing regional telehealth groups and gather lessons to be learned from them; (2) Form a telehealth advisory group to work with regional groups to compile telehealth initiatives, identify international protocols in telehealth already in existence, and solicit feedback before setting international standards; and (3) Increase corporate partnerships in the fields of telehealth and telecommunications, and invite corporations to send delegates to future APCDM meetings. This should be an initiative of the APCDM, the World Association of Disaster and Emergency Medicine (WADEM), or the European Society of Emergency Medicine. EDUCATION AND RESEARCH: (1) Formalize education in disaster medicine and management. The World Health Organization and WADEM should take a leadership role; (2) WADEM is requested to hold a conference with a focus on qualitative research; (3) WHO is requested to continue the provision of international research teams, but to advocate for the development of national disaster research infrastructure; (4) Make research findings and reports available on web sites of such organizations as WHO and PAHO; (5) Develop the translation of research for community utilization. The WHO and PAHO are organizations that are requested to consider this action; and (6) WADEM/APCDM are requested to focus future conferences on applied research. INFORMATION AND DATA: (1) Create an "Information and Data Clearinghouse on Disaster Management" to collect, collate, and disseminate information; (2) Collect data using standardized tools, such as CAR or Hazmat indices; (3) Analyze incentives and disincentives for disaster readiness and establish mechanisms for addressing the obstacles to preparedness; and (4) WADEM is requested to develop a web site providing a resource list of interdisciplinary institutions and response activities, organized by country, topic, and research interests. Links to other pertinent web sites should be provided. INTERDISCIPLINARY DEVELOPMENT: (1) Focus on the interdisciplinary nature of disaster response through more conferences encompassing grassroots efforts and through WADEM publications; (2) Develop and apply a standardized template of Needs Assessment for use by multidisciplinary teams. Team Needs Assessment is essential to determine the following: (a) Local response and international assistance required; (b) Appropriate command system; and (c) Psychosocial impact and support necessary. PSYCHOSOCIAL ASPECTS: (1) Incorporate relief for caregivers into action plans. This should include prime family members who also are caregivers; and (2) Implement measures that give survivors control over the recovery process. RESPONSE MANAGEMENT: (1) Define relationships and roles between governments, military and security personnel, non-governmental organizations (NGOs), and civic groups. Use an international legal framework and liability to reinforce accountability of disaster responders; (2) Establish a more sophisticated use of the media during disasters; (3) Establish standards in key areas. WADEM is requested to write "White Papers" on standards for the following areas: (a) management, (b) health/public health, (c) education/training, (d) psychosocial, and (e) disaster plans; (4) Establish task forces to anticipate and resolve issues around evolving and emerging disasters (e.g., chemical and biological terrorism, landmines, emerging infectious diseases). WADEM was again identified as the vehicle for promoting this action. The responsibility of the next meeting of the Asia-Pacific Conference on Disaster Medicine will be to measure progress made in these areas by assessing how well these collective decisions have been implemented.

Disaster and subsequent healthcare utilization: a longitudinal study among victims, their family members, and control subjects

BACKGROUND: The impact of disasters on primary healthcare utilization is largely unknown. Moreover, it is often overlooked how disaster affects those closest to the primary victims, their family members. OBJECTIVE: The objective of this study was to examine the long-term effects of a catastrophic fire on primary healthcare utilization. RESEARCH DESIGN: We conducted a prospective, population-based cohort study covering 1 year pre- and 3 years postfire. Utilization data were extracted from primary care records. SUBJECTS: Subjects consisted of 286 disaster victims, 802 family members of disaster victims, 3722 community control subjects, and 10,230 patients from a national reference population. MEASURES: As outcome measures, we studied 1) the annual number of contacts in primary care and 2) the annual number of contacts for problems related to mental health. Determinants are injury characteristics of victims and bereavement. All analyses control for age, gender, and insurance status. RESULTS: Being an uninjured victim who witnessed the disaster increases the number of contacts by a factor of 1.55 during the first year postfire (95% confidence interval [CI], 1.35-1.78). Uninjured victims contact the family practitioner more often for mental health-related problems than adolescent community control subjects (incidence rate ratio [IRR], 4.54; 95% CI, 1.69-12.20). In adult family members, the loss of a child predicts overall utilization (IRR, 1.88; 95% CI, 1.35-2.63) and utilization for mental health (IRR, 8.69; 95% CI, 2.10-35.92) during the first year postfire. CONCLUSION: Attention should be paid to the primary care needs of bereaved individuals and those who have witnessed the disaster.     

Sharing international experiences in disasters: summary and action plan

INTRODUCTION: The discussions in this theme provided an opportunity to share specific experiences with disasters that occurred outside of the Asia-Pacific Rim. METHODS: Details of the methods used are provided in the preceding paper. The chairs moderated all presentations and produced a summary that was presented to an assembly of all of the delegates. Since the findings from the Theme 7 and Theme 3 groups were similar, the chairs of both groups presided over one workshop that resulted in the generation of a set of action plans that then were reported to the collective group of all delegates. RESULTS: The main points developed during the presentations and discussion included: (1) disaster response planning, (2) predetermined command and organizational structure, (3) rapid response capability, (4) mitigation, and (5) communications and alternatives. DISCUSSION: The action plans presented are in common with those presented by Theme 3, and include: (1) plan disaster responses including the different types, identification of hazards, training based on experiences, and provision of public education; (2) improving coordination and control; (3) maintaining communications assuming infrastructure breakdown; (4) maximizing mitigation through standardized evaluations, creation of a legal framework, and recognition of advocacy and public participation; and (5) providing resources and knowledge through access to existing therapies, using the media, and increasing decentralization of hospital inventories. CONCLUSIONS: Most of the problems that occurred outside the Asia-Pacific rim relative to disaster management are similar to those experienced within it. They should be addressed in common with the rest of the world.     

Disaster management following the Chi-Chi earthquake in Taiwan

The earthquake that occurred in Taiwan on 21 September 1999 killed >2,000 people and severely injured many survivors. Despite the large scale and sizeable impact of the event, a complete overview of its consequences and the causes of the inadequate rescue and treatment efforts is limited in the literature. This review examines the way different groups coped with the tragedy and points out the major mistakes made during the process. The effectiveness of Taiwan's emergency preparedness and disaster response system after the earthquake was analyzed. Problems encountered included: (1) an ineffective command center; (2) poor communication; (3) lack of cooperation between the civil government and the military; (4) delayed prehospital care; (5) overloading of hospitals beyond capacity; (6) inadequate staffing; and (7) mismanaged public health measures. The Taiwan Chi-Chi Earthquake experience demonstrates that precise disaster planning, the establishment of one designated central command, improved cooperation between central and local authorities, modern rescue equipment used by trained disaster specialists, rapid prehospital care, and medical personnel availability, as well earthquake-resistant buildings and infrastructure, are all necessary in order to improve disaster responses.     

Teaching emergency preparedness to restricted-budget families

OBJECTIVE: To fulfill the health teaching and promotion responsibilities of public health nurses, a teaching intervention was devised to prepare low-income, low-resource families to survive a worst-case disaster scenario. The purpose of this study is to introduce that plan. DESIGN: Teaching sessions were held to increase awareness about disaster preparedness and to provide the resources necessary for preparing disaster kits on a restricted budget. SAMPLE: This project focused on families enrolled at the Children's Relief Nursery in Portland, Oregon's St. Johns District. MEASUREMENTS: Posttest assessments and client follow-up at 3, 6, and 12 months were used to assess the effectiveness of the curriculum and follow-through on kit preparation. RESULTS: A replicable teaching tool was successfully developed, and the interest and commitment of community partners dedicated to assisting restricted-budget families was secured. CONCLUSIONS: States' disaster plans hinge on individuals' implementation of their own survival plans, and it is vital that these individuals be made aware of their responsibility. It is truly a matter of life and death that families possess the skills, knowledge, and resources to carry out a disaster survival plan successfully, and it is the ethical responsibility of the public health nurse to intervene.     

Disaster preparedness for vulnerable persons receiving in-home, long-term care in South Carolina

PURPOSE: The purpose of this study was to examine how agencies in South Carolina that provide in-home health care and personal care services help older and/or disabled clients to prepare for disasters. The study also examines how agencies safeguard clients' records, train staff, and how they could improve their preparedness. METHODS: The relevant research and practice literature was reviewed. Nine public officials responsible for preparedness for in-home health care and personal care services in South Carolina were interviewed. A telephone survey instrument was developed that was based on these interviews and the literature review. Administrators from 16 agencies that provide in-home personal care to 2,147 clients, and five agencies that provide in-home health care to 2,180 clients, were interviewed. Grounded theory analysis identified major themes in the resulting qualitative data; thematic analysis organized the content. RESULTS: Federal regulations require preparedness for agencies providing in-home health care ("home health"). No analogous regulations were found for in-home personal care. The degree of preparedness varied substantially among personal care agencies. Most personal care agencies were categorized as "less" prepared or "moderately" prepared. The findings for agencies in both categories generally suggest lack of preparedness in: (1) identifying clients at high risk and assisting them in planning; (2) providing written materials and/or recommendations; (3) protecting records; (4) educating staff and clients; and (5) coordinating disaster planning and response across agencies. Home health agencies were better prepared than were personal care agencies. However, some home health administrators commented that they were unsure how well their plans would work during a disaster, given a lack of training. The majority of home health agency administrators spoke of a need for better coordination and/or more preparedness training. CONCLUSIONS: Agencies providing personal care and home health services would benefit from developing stronger linkages with their local preparedness systems. The findings support incorporating disaster planning in the certification requirements for home health agencies, and developing additional educational resources for administrators and staff of personal care agencies and their clients.
