A longitudinal study of the psychological morbidity in children due to a natural disaster.

This longitudinal study examined the psychological impact of a bushfire disaster on a group of 808 children aged from 5 to 12. Contrary to prediction, the prevalence of behaviour and emotional problems 2 months after the fire was less than the prevalence in a carefully selected comparison group. Rather than decrease with time, the prevalence of psychological morbidity increased significantly, being as great 26 months after the disaster as at 8 months.

Psychosocial sequelae of the 1989 Newcastle earthquake: III. Role of vulnerability factors in post-disaster morbidity.

BACKGROUND: This paper examines the contributions of dispositional and non-dispositional factors to post-disaster psychological morbidity. Data reported are from the 845 participants in the longitudinal component of the Quake Impact Study. METHODS: The phase 1 survey was used to construct dimensional indices of threat and disruption exposure. Subsequently, a range of dispositional characteristics were measured, including neuroticism, personal hopefulness and defence style. The main morbidity measures were the General Health Questionnaire (GHQ-12) and Impact of Event Scale (IES). RESULTS: Dispositional characteristics were the best predictors of psychological morbidity throughout the 2 years post-disaster, contributing substantially more to the variance in morbidity (12-39%) than did initial exposure (5-12%), but the extent of their contribution was greater for general (GHQ-12) than for post-traumatic (IES) morbidity. Among the non-dispositional factors, avoidance coping contributed equally to general and post-traumatic morbidity (pr = 0.24). Life events since the earthquake (pr = 0.18), poor social relationships (pr = -0.25) and ongoing earthquake-related disruptions (pr = 0.22) also contributed to general morbidity, while only the latter contributed significantly to post-traumatic morbidity (pr = 0.15). CONCLUSIONS: Medium-term post-earthquake morbidity appears to be a function of multiple factors whose contributions vary depending on the type of morbidity experienced and include trait vulnerability, the nature and degree of initial exposure, avoidance coping and the nature and severity of subsequent events.

The chemical disaster response system in Japan.

During the last decade, Japan has experienced the largest burden of chemical terrorism-related events in the world, including the: (1) 1994 Matsumoto sarin attack; (2) 1995 Tokyo subway sarin attack; (3) 1998 Wakayama arsenic incident; (4) 1998 Niigata sodium-azide incident; and (5) 1998 Nagano cyanide incident. Two other intentional cyanide releases in Tokyo subway and railway station restrooms were thwarted in 1995. These events spurred Japan to improve the following components of its chemical disaster-response system: (1) scene demarcation; (2) emergency medical care; (3) mass decontamination; (4) personal protective equipment; (5) chemical detection; (6) information-sharing and coordination; and (7) education and training. Further advances occurred as result of potential chemical terrorist threats to the 2000 Kyushu-Okinawa G8 Summit, which Japan hosted. Today, Japan has an integrated system of chemical disaster response that involves local fire and police services, local emergency medical services (EMS), local hospitals, Japanese Self-Defense Forces, and the Japanese Poison Information Center.

Vaccine administration by paramedics: a model for bioterrorism and disaster response preparation.

The events of 11 September 2001 have had a profound effect on disaster planning efforts in the United States. This is true especially in the area of bioterrorism. One of the major tenets of bioterrorism response is the vaccination of at-risk populations. This paper investigates the efficacy of training emergency medical services paramedics to administer vaccines in public health settings as preparation for and response to bioterrorism events and other disaster events. The concept of vaccination administration by specially trained paramedics is not new. Various programs to provide immunizations for emergency services personnel and at-risk civilian populations have been reported. Vaccination programs by paramedics should follow the guidelines of the National Vaccine Advisory Committee of the Centers for Disease Control and Prevention (CDC). This paper compares the seven standards of the CDC guidelines to routine paramedic practice and education. It is concluded that paramedics are adequately trained to administer vaccines. However, specific training and protocols are needed in the areas of administrative paperwork and patient education. A proposed outline for a paramedic-training program is presented.

Disaster intervention: long-term psychosocial benefits in Armenia.

This paper describes a unique situation in which disaster intervention following a massive earthquake led to significant, uninterrupted, psychosocial benefits to the entire country, and an intervention program that continues to evolve. The mental health program initially provided service to the victims, and then, training to local professionals during which personnel simultaneously conducted clinical research. Members of the mental health team made a life-long commitment to the country, and continue their activities to expand its impact on public health policy. The difficult history and life circumstances of the Armenian people provided the opportunity for disaster interventions to have extensive psychosocial benefits.

The incident command system in disasters: evaluation methods for a hospital-based exercise.

OBJECTIVES: No universally accepted methods for objective evaluation of the function of the Incident Command System (ICS) in disaster exercises currently exist. An ICS evaluation method for disaster simulations was derived and piloted. METHODS: A comprehensive variable list for ICS function was created and four distinct ICS evaluation methods (quantitative and qualitative) were derived and piloted prospectively during an exercise. Delay times for key provider-victim interactions were recorded through a system of data collection using participant- and observer-based instruments. Two different post-exercise surveys (commanders, other participants) were used to assess knowledge and perceptions of assigned roles, organization, and communications. Direct observation by trained observers and a structured debriefing session also were employed. RESULTS: A total of 45 volunteers participated in the exercise that included 20 mock victims. First, mean, and last victim delay times (from exercise initiation) were 2.1, 4.0, and 9.3 minutes (min) until triage, and 5.2, 11.9, and 22.0 min for scene evacuation, respectively. First, mean, and last victim delay times to definitive treatment were 6.0, 14.5, and 25.0 min. Mean time to triage (and range) for scene Zones I (nearest entrance), II (intermediate) and III (ground zero) were 2.9 (2.0-4.0), 4.1 (3.0-5.0) and 5.2 (3.0-9.0) min, respectively. The lowest acuity level (Green) victims had the shortest mean times for triage (3.5 min), evacuation (4.0 min), and treatment (10.0 min) while the highest acuity level (Red) victims had the longest mean times for all measures; patterns consistent with independent rather than ICS-directed rescuer activities. Specific ICS problem areas were identified. CONCLUSIONS: A structured, objective, quantitative evaluation of ICS function can identify deficiencies that can become the focus for subsequent improvement efforts.

International medical response to a natural disaster: lessons learned from the Bam earthquake experience.

An earthquake measuring 6.5 on the Richter scale devastated Bam, Iran on the morning of 26 December 2003. Due to the great health demands and collapse of health facilities, international aid could have been a great resource in the area. Despite sufficient amounts and types of resources provided by international teams, the efficacy of international assistance was not supported in Bam, as has been experienced in similar events in other countries. Based on the observations in the region and collecting and analyzing documents about the disaster, this manuscript provides an overview of the medical needs during the disaster and describes the international medical response. The lessons learned include: (1) necessity of developing a national search and rescue strategy; (2) designing an alarm system; (3) establishing an international incident command system; (4) increasing the efficacy of the arrival and implementation of a foreign field hospital; and (5) developing a flowchart for deploying international assistance.

Principles of disaster management. Lesson 7: Management leadership styles and methods.

This lesson explores the use of different management leadership styles and methods that are applied to disaster management situations. Leadership and command are differentiated. Mechanisms that can be used to influence others developed include: 1) coercion; 2) reward; 3) position; 4) knowledge; and 5) admiration. Factors that affect leadership include: 1) individual characteristics; 2) competence; 3) experience; 4) self-confidence; 5) judgment; 6) decision-making; and 8) style. Experience and understanding the task are important factors for leadership. Four styles of leadership are developed: 1) directive; 2) supportive; 3) participative; and 4) achievement oriented. Application of each of these styles is discussed. The styles are discussed further as they relate to the various stages of a disaster. The effects of interpersonal relationships and the effects of the environment are stressed. Lastly, leadership does not just happen because a person is appointed as a manager--it must be earned.

Principles of disaster management lesson 11: personnel evaluation.

A disaster manager must be able to evaluate staff members in order to make effective staffing decisions during the transitions between phases of a disaster and to help improve the performance of the operation by determining what aspects of an individual's work needs improvement. Criteria for personnel appraisal and measures of performance, objective or subjective, are essential to conduct a fair and thorough evaluation. Errors introduce bias into the appraisal in the form of a "halo" effect, harsh or lenient ratings, a central tendency error, or recency effect, but recognition of these errors helps reduce their effect. A results-based appraisal program is favored because it focuses on what the worker achieves. Regular appraisal periods are suggested for optimal improvement in performance. Suggestions are given for an effective personnel appraisal, such as focusing on positive work performance, being aware of biases in judging people, and being specific when citing examples of work performance.

Post-disaster malaria in Costa Rica.

INTRODUCTION: In recent years, controversy has surrounded the issue of whether infectious disease should be considered a serious potential consequence of natural disasters. This article contributes to this debate with evidence of a significant outbreak of malaria in Costa Rica's Atlantic region after the 1991 earthquake and subsequent floods. METHODS: This study is an epidemiologic investigation of the incidence of malaria for the periods of 22 months before the April 1991 Limón earthquake and for 13 months afterward. Data were obtained from the Costa Rican Ministry of Health's malaria control program. RESULTS: Some of the cantons in the region experienced increases in the incidence of malaria as high as 1,600% and 4,700% above the average monthly rate for the preearthquake period (p < or = 0.01). Causal mechanisms are postulated as relating to changes in human behavior (increased exposure to mosquitoes while sleeping outside, and a temporary pause in malaria control activities), changes in the habitat that were beneficial to mosquito breeding (landslide deforestation, river damming, and rerouting), and the floods of August 1991. CONCLUSIONS: It is recommended that there be enhanced awareness of the potential consequences of disaster-wrought environmental changes. Date of Event: 22 April 1991; Type: Earthquake, 7.4 Richter scale; LOCATION: Costa Rica; Number of deaths and casualties: 54 deaths and 505 moderate to severe injuries.

Disaster triage: START, then SAVE--a new method of dynamic triage for victims of a catastrophic earthquake.

Triage of mass casualties in situations in which patients must remain on-scene for prolonged periods of time, such as after a catastrophic earthquake, differs from traditional triage. Often there are multiple scenes (sectors), and the infrastructure is damaged. Available medical resources are limited, and the time to definitive care is uncertain. Early evacuation is not possible, and local initial responders cannot expect significant outside assistance for at least 49-72 hours. Current triage systems are based either on a shorter time to definitive care or on a longer time to initial triage. The Medical Disaster Response (MDR) project deals with the scenario in which specially trained, local health-care providers evaluate patients immediately after the event, but cannot evacuate patients to definitive care. For this type of scenario, a dynamic triage methodology was developed that permits the triage process to evolve over hours or even days, thereby maximizing patient survival and resulting in a more efficient use of resources. This MDR system incorporates a modified version of "Simple Triage and Rapid Treatment" (START) that substitutes radial pulse for capillary refill, coupled with a system of secondary triage termed, "Secondary Assessment of Victim Endpoint" (SAVE). The SAVE triage was developed to direct limited resources to the subgroup of patients expected to benefit most from their use. The SAVE assesses survivability of patients with various injuries and, on the basis of trauma statistics, uses this information to describe the relationship between expected benefits and resources consumed. Because early transport to an intact medical system is unavailable, this information guides treatment priorities in the field to a level beyond the scope of the START methodology. Pre-existing disease and age are factored into the triage decisions. An elderly patient with burns to 70% of body surface area is unsalvageable under austere field conditions and would require the use of significant medical resources-both personnel and equipment-and would be triaged to an "expectant area." Conversely, a young adult with a Glasgow Coma Scale score of 12 who requires only airway maintenance would use few resources and would have a reasonable chance for survival with the interventions available in the field, and would be triaged to a "treatment" area. The START and SAVE triage techniques are used in situations in which triage is dynamic, occurs over many hours to days, and only limited, austere, field, advanced life support equipment is readily available. The MDR-SAVE methodology is the first systematic attempt to use triage as a tool to maximize patient benefit in the immediate aftermath of a catastrophic disaster.

Coping self-efficacy perceptions as a mediator between acute stress response and long-term distress following natural disasters.

The mediating effect of coping self-efficacy (CSE) perceptions between acute stress responses (ASR) and 1-year distress following two disasters was tested. Between 3 and 8 weeks after the second disaster and again at 1 year, 46 residents completed questionnaires. Posttraumatic Stress Disorder (PTSD) symptoms and global distress served as outcomes. Multiple regression demonstrated that ASR and Time I CSE were significant predictors of both Time 1 outcomes. Time 1 PTSD symptoms and Time 2 CSE were significant factors for Time 2 PTSD symptoms. Gender was significant for Time 2 PTSD symptoms, but not for Time 2 global distress. Longitudinally, Time 1 CSE predicted Time 2 PTSD symptoms, but not general distress. CSE mediated between ASR and both psychological outcomes at Time 2. Coping self-efficacy perceptions provide a possible intervention target.

Ethical issues pertaining to research in the aftermath of disaster.

In January 2003, The New York Academy of Medicine and the National Institute of Mental Health sponsored a meeting entitled "Ethical Issues Pertaining to Research in the Aftermath of Disaster." The purpose of the meeting was to bring together various experts to examine evidence concerning the impact of research on trauma-exposed participants, review the applicable ethical principles and policies concerning protection of human subjects, and offer guidance to investigators, IRBs, public health and local officials, and others interested in assuring that research in the aftermath of a disaster is conducted in a safe and ethical manner. This article summarizes the group's key findings and outlines potential considerations for those working in this field.

The concept of vulnerability in disaster research.

The concept of vulnerability in research derives from a specific set of historical circumstances relating to abuses in biomedical research. Now so many people and groups have been labeled vulnerable that the concept has lost much of its force. In disaster research, participants should not be automatically considered vulnerable unless they are legally designated as such, for example, children. Instead specific aspects of the research should be thoroughly examined. Examples are the potential for the participants to be pressured to participate in several protocols, political or social turmoil surrounding the disaster, and cognitive impairments or mental health problems. In addition to a careful consent process, there should be procedures in place to provide assistance to participants who experience serious distress.

Perceived benefit and mental health after three types of disaster.

The study of growth and perceived benefit after traumatic events has been hailed as one of the most promising directions for stress research. This research, however, has been limited by several methodological limitations. These limitations are addressed in this prospective study, which examines perceived benefit and mental health adjustment after 3 different types of disaster. Survivors of a tornado in Madison, Florida, had the highest rates of perceived benefit, followed by survivors of a mass killing in Killeen, Texas, and survivors of a plane crash in Indianapolis, Indiana. Perceived benefit 4-6 weeks postdisaster predicted posttraumatic stress disorder 3 years later. Perceived benefit moderated the effect of severity of disaster exposure on mental health diagnosis change over time. Without perceived benefit, as exposure severity increased, the amount of recovery decreased. If benefit was perceived, as exposure severity increased, the amount of recovery increased. Implications for clinical interventions and future research are discussed.

A test of the social support deterioration model in the context of natural disaster.

This prospective longitudinal study examined stress-mediating potentials of 3 types of social support: social embeddedness, perceived support from nonkin, and perceived support from kin. As participants in a statewide panel study, 222 older adults were interviewed once before and twice after a severe flood. It was hypothesized that disaster exposure (stress) would influence depression directly and indirectly, through deterioration of social support. LISREL analyses indicated that postdisaster declines in social embeddedness and nonkin support mediated the immediate and delayed impact of disaster stress. No evidence was found for the mediational role of kin support. Findings are in accord with conceptualizations of social support as an entity reflecting dynamic transactions among individuals, their social networks, and environmental pressures.
