Air medical response to the 1990 Will County, Illinois, tornado.

At least 29 people were killed and over 300 injured on August 28, 1990, when a powerful tornado cut a path of destruction through the outskirts of Chicago. The tornado's destructive force began a mammoth rescue effort from over 50 emergency medical service agencies, 80 ambulances, 1,000 rescue personnel, and Chicago's two air medical helicopters. The EMS effort was supplemented by an equally large response from police, fire, heavy rescue, K-9, and other emergency teams across north and central Illinois. Medical mass casualty incident procedures were activated and coordinated through the Will-Grundy Emergency Medical Services System, located at Silver Cross Hospital in Joliet. The towns of Crest Hill, Plainfield, and Joliet were the hardest hit, with more than $200 million in damages. The tornado strained not only the ground-based EMS and rescue systems, but taxed the resources of the city's air medical programs as well. This paper reviews the response by critical care air medical transport teams to this natural disaster.

Psychological aspects of traumatic injury in children and adolescents.

Each year millions of children are exposed to some form of extreme traumatic stressor. These traumatic events include natural disasters (e.g., tornadoes, floods, hurricanes), motor vehicle accidents, life-threatening illnesses and associated painful medical procedures (e.g., severe burns, cancer, limb amputations), physical abuse, sexual assault, witnessing domestic or community violence, kidnapping, and sudden death of a parent. During times of war, violent and nonviolent trauma (e.g., lack of fuel and food) may have terrible effects on children's adjustment. The events of September 11, 2001 and the unceasing suicidal attacks in the Middle East underscore the importance of understanding how children and adolescents react to disasters and terrorism. The body of literature related to children and their responses to disasters and trauma is growing. Mental health professionals are increasing their understanding about what factors are associated with increased risk (vulnerability) and affect how children cope with traumatic events. Researchers recognize that children's responses to major stress are similar to adults' (reexperiencing the event, avoidance, and arousal) and that these responses are not transient. A review of the literature indicates that PTSD is the most common psychiatric disorder after traumatic experiences, including physical injuries. There is also evidence for other comorbid conditions, including mood, anxiety, sleep, conduct, learning, and attention problems. In terms of providing treatment, CBT emerges as the best validated therapeutic approach for children and adolescents who experienced trauma-related symptoms, particularly symptoms associated with anxiety or mood disorders. The best approach to the injured child requires injury and pain assessment followed by specific interventions, such as pain management, brief consultation, and crisis intervention immediately after the specific traumatic event. Family support also may be necessary to help the family through this difficult period. The main conclusion that arises from the research on resilience in development is that extraordinary resilience and recovery power of children depend on basic human protective systems operating in their favor. This finding has produced a fundamental change in the framework for understanding and helping children at high risk or already in trouble. This shift is evident in a changing conceptualization of the goals of prevention and intervention that currently address competence and problems. Strategies for fostering resilience described in this article should be tested in future controlled psychotherapy trials to verify their efficacy on children's protective factors.

Phenomenological study of the North Dakota flood experience and its impact on survivors' health.

Grand Forks, North Dakota, was devastated by an unprecedented flood, forcing the evacuation of an entire community of 50,000 residents in 72 hours. A qualitative descriptive study with use of phenomenological methods was conducted 6 months after the flooding. Its purpose was to gain a deeper understanding of the meaning of a traumatic flood experience and its influence on the health of the residents of Grand Forks. Data were generated through interviews, observations, and media reports. The sample included 3 female and 3 male residents of the city of Grand Forks, North Dakota, who ranged in age from 26 to 77 years. Five essential themes were identified: (1) shock and disbelief, (2) uncertainty, (3) grief and loss, (4) emotional exhaustion, and (5) hope and meaning. The participants' descriptions of emotional exhaustion were similar to those found with survivors of posttraumatic stress disorder. Older adults appeared to be especially vulnerable. Nurses who are aware of the effects of natural disasters, particularly flooding, may be better able to identify vulnerable populations and understand the health needs of other survivors.

[Erythrocyte concentrated and air transport: evaluation of quality].

The available supply of blood products determines the resuscitation capabilities after natural disasters or armed conflicts. Air flight reduces transport delay. The purpose of the present study was to assess the quality of red blood cell concentrates (RCC) immediately after air transport (j0) and after preservation (j30). We exposed RCC to a real air flight (P) or to low pressure (V) corresponding to an air transport in experimental conditions. The quality of RCC was altered immediately after only the real air flight (hemolysis P = 0.11% versus 0.04% for witness (T)). These alterations were not observed immediately after the simulated flight (hemolysis V = 0.02%). After preservation, the RCC was altered both for those exposed to an air flight or to a low pressure (hemolysis: P = 1.09%, V = 0.78%, T = 0.25%). Other biological alterations (pH, K+, hemoglobin level) suggested that pressure variations are not the only one responsible constraint. Other studies are necessary to point the mechanism and the optimal life of conservation after flight. Exposure of preserved red blood cells to air transport alters their therapeutic properties during aging. However, the therapeutic use of RCC thus transported is not questioned.

Cognitive processing in post-trauma reactions: some preliminary findings.

The current study investigated a model of post-trauma reactions proposed initially by McFarlane (1988 a). Two separate data sets, one obtained following a multiple shooting and the other reported by McFarlane following a natural disaster, were examined. The findings of both studies provide support for a cognitive processing conceptualization of the development of post-trauma reactions.

A brief behavioural treatment of chronic post-traumatic stress disorder in earthquake survivors: results from an open clinical trial.

BACKGROUND: Natural disasters such as earthquakes affect large numbers of people. Given the extent of the mental health problem following earthquakes, brief, effective and cost-effective treatment interventions are urgently needed. The present study examined whether cognitive-behavioural treatment could be shortened to a minimum number of sessions without undermining its effectiveness in post-traumatic stress disorder (PTSD). METHOD: The study participants (N=231) were consecutive referrals to five project sites in the earthquake region in Turkey a mean of 13 months after the disaster. A modified behavioural treatment (BT) was used, which involved self-exposure instructions based on an enhancement of 'sense of control' rather than a habituation rationale and minimal cognitive interventions. The duration of treatment was variable, involving as many sessions as required for clinical improvement. Survival analysis was used to explore the minimum number of sessions required for clinical improvement, and multiple regression analysis to examine the predictors of outcome. RESULTS: The survivors received a mean of 4-3 sessions. Significant treatment effects and clinically meaningful effect sizes were noted on all measures. The treatment improved all PTSD and depression symptoms. The cumulative proportion of improved cases was 76% after one session and 88% after two sessions. No baseline variable predicted treatment outcome. CONCLUSIONS: The modified BT appears to be promising as an effective one- or two-session intervention for earthquake survivors. It may be particularly useful in large-scale disasters as a cost-effective treatment that can be relatively easily disseminated to mass populations. Further research is needed to clarify the possible role of a treatment focus on sense of control in rapid recovery from traumatic stress.

Associations of pre-trauma attributes and trauma exposure with screening positive for PTSD: analysis of a community-based study of 2,085 young adults.

BACKGROUND: While pre-trauma personality and mental health measures are risk factors for post-traumatic stress disorder (PTSD), such information is usually obtained following the trauma and can be influenced by post-trauma distress. We used data collected from a community-based survey of young adults before and after a major natural disaster to examine the extent to which participants' traumatic experiences, demographic and pre-trauma risk factors were associated with their screening positive for PTSD when re-interviewed. METHOD: A representative selection of 2,085 young adults from the Australian Capital Territory and environs, interviewed in 1999 as part of a longitudinal community-based survey, were re-interviewed 3-18 months after a major bushfire had occurred in the region. When re-interviewed, they were asked about their experiences of trauma threat, uncontrollable and controllable traumatic experiences and their reaction to the fire. They were also screened for symptoms of fire-related PTSD experienced in the week prior to interview. RESULTS: Four-fifths of participants were exposed to the trauma with around 50% reporting having experienced uncontrollable traumatic events. Reporting PTSD symptoms was associated with being female, having less education, poorer mental health and higher levels of neuroticism prior to the trauma. Particular fire experiences, including being evacuated and feeling very distressed during the disaster, were more strongly associated with PTSD symptoms compared with pre-trauma measures. CONCLUSIONS: While demographic and pre-trauma mental health increased the likelihood of reporting PTSD symptoms, exposure to trauma threat and reaction to the trauma made greater contributions in explaining such symptoms as a result of this disaster.

Childhood adversity and adult psychiatric disorder in the US National Comorbidity Survey.

BACKGROUND: Survey data are presented on the associations between retrospectively reported childhood adversities and subsequent onset and persistence of DSM-III-R disorders. METHODS: Data come from the US National Comorbidity Survey, a large survey of the US household population. RESULTS: Twenty-six adversities were considered, including loss events (e.g. parental divorce), parental psychopathologies (e.g. maternal depression), interpersonal traumas (e.g. rape) and other adversities (e.g. natural disaster). These adversities were consistently associated with onset, but not persistence, of DSM-III-R mood disorders, anxiety disorders, addictive disorders and acting out disorders. Most bivariate associations with onset attenuated in models that controlled for clustering of adversities and for lifetime co-morbidities among psychiatric disorders. Multivariate effects of adversities in logistic models were additive, which means that they have multiplicative effects on probability of disorder onset. Adversities showed little specificity. An analysis of time decay showed that the effects of childhood adversities on disorder onset persist beyond childhood. CONCLUSIONS: The existence of strong clustering among childhood adversities and lifetime co-morbidity among adult disorders means that caution is needed in interpreting the results of previous single-adversity single-disorder studies as documenting unique effects of specific childhood adversities on specific adult disorders. Future studies need to assess a broader range of adversities and disorders and to explore the existence and effects of commonly occurring adversity clusters. Replication is needed to verify that the effects of childhood adversities are mostly on first onset rather than on the creation of vulnerabilities that lead to increased risk of persistence.

Life events and post-traumatic stress: the development of a new measure for children and adolescents.

BACKGROUND: A new interview measure of life events and post-traumatic stress disorder (PTSD) has been developed for children and adolescents aged 9 through 17, for use in both epidemiological and clinical studies. It includes 'high magnitude' events associated with PTSD as well as other 'low magnitude' events. METHOD: The interview is designed as a module of the Child and Adolescent Psychiatric Assessment, an interviewer-based interview conducted with parent and child separately by trained lay interviewers. The module includes: (1) questions about a wide range of events; (2) a screen for key PTSD symptoms (painful recall, avoidance, hypervigilance); and (3) a detailed interview on all PTSD symptoms, including onset, duration, severity and co-morbidity. A test-retest reliability study was conducted with 58 parents and children, who were interviewed twice by different interviewers. RESULTS: Intraclass correlations were 0.72 (child) and 0.83 (parent) for high magnitude events, and 0.62 (child) and 0.58 (parent) for low magnitude events. Kappa coefficients ranged from high for violence and sexual abuse to low for child reports of serious accidents and natural disasters. The reliability of the PTSD screen symptoms was fair to excellent (kappa = 0.40-0.79), and reliability of PTSD symptoms in those who passed the screen was excellent (ICC = 0.94-0.99). Compared with a general population sample (N = 1015), the clinic-referred subjects and their parents were twice as likely to report a traumatic event and, depending on the event, up to 25 times as likely to report symptoms of PTSD. CONCLUSIONS: The results support the reliability and discriminant validity of the measure.

Prehospital care of tsunami victims in Thailand: description and analysis.

INTRODUCTION: On 26 December 2004 at 09:00 h, an earthquake of 9.0 magnitude (Richter scale) struck the area off of the western coast of northern Sumatra, Indonesia, triggering a Tsunami. As of 25 January 2005, 5,388 fatalities were confirmed, 3,120 people were reported missing, and 8,457 people were wounded in Thailand alone. Little information is available in the medical literature regarding the response and restructuring of the prehospital healthcare system in dealing with major natural disasters. OBJECTIVE: The objective of the study was to analyze the prehospital medical response to the Tsunami in Thailand, and to identify possible ways of improving future preparedness and response. METHODS: The Israeli Defense Forces (IDF) Home Front Command Medical Department sent a research delegation to study the response of the Thai medical system to the 2004 earthquake and Tsunami disaster. The delegation met with Thai healthcare and military personnel, who provided medical care for and evacuated the Tsunami victims. The research instruments included questionnaires (open and closed questions), interviews, and a review of debriefing session reports held in the days following the Tsunami. RESULTS: Beginning the day after the event, primary health care in the affected provinces was expanded and extended. This included: (1) strengthening existing primary care facilities with personnel and equipment; (2) enhancing communication and transportation capabilities; (3) erecting healthcare facilities in newly constructed evacuation centers; (4) deploying mobile, medical teams to make house calls to flood refugees in affected areas; and (5) deploying ambulance crews to the affected areas to search for survivors and provide primary care triage and transportation. CONCLUSION: The restructuring of the prehospital healthcare system was crucial for optimal management of the healthcare needs of Tsunami victims and for the reduction of the patient loads on secondary medical facilities. The disaster plan of a national healthcare system should include special consideration for the restructuring and reinforcement prehospital system.

The effects of Hurricane Mitch on a community in northern Honduras.

INTRODUCTION: Hurricane Mitch was an event described as one of the most damaging recent natural disasters in our hemisphere. This study examined its effects on a community of 5,000 residents in northern Honduras. METHODS: Survey responses of 110 attendants at an ambulatory clinic 4 months after the event were analyzed. Correlates were established between demographic and housing characteristics and morbidity and mortality. RESULTS: The availability of food, water, and medical care decreased significantly immediately after the hurricane, but by four months afterward returned to baseline values. Residents reported emotional distress correlated with the loss of a house or intrafamilial illness or mortality. Diarrheal illnesses more commonly were found in households with poor chronic access to medical care. The use of cement block housing correlated with availability of food or running water, with access to medical care and vaccinations, and with a reduced frequency of diarrhea or headaches in the immediate post-hurricane phase. CONCLUSIONS: Improvements in housing construction appear to be the most effective preventive measure for withstanding the effects of future hurricanes in tropical regions similar to northern Honduras.

Natural hazards: causes and effects. Lesson 7-Drought.

Drought has long been recognized as one of the most insidious causes of human misery. Today, it is the natural disaster that annually claims the most victims. Its ability to cause widespread misery is estimated to be increasing. While generally associated with semiarid climates, drought may occur in areas that normally enjoy adequate rainfall and moisture. In the broadest sense, any lack of water for the normal needs of agriculture, livestock, industry, or human population may be termed as a drought. The cause may be lack of supply, contamination of supply, inadequate storage or conveyance facilities, or abnormal demand. Drought is a condition of climatic dryness severe enough to reduce soil moisture and water below the minimums necessary for sustaining plant, animal, and human life. Drought usually is accompanied by hot, dry winds and may be followed by damaging floods. More socially relevant than technically correct is the definition used by Ari Toubo Eibrahim, the minister of agriculture in Niger, who has said that a drought is "Not as much water as the people need."

Recent advances in the understanding and treatment of anxiety disorders. Resilience: determinants, measurement, and treatment responsiveness.

In human terms, resilience is an ability to cope with stress and varies with context, time, age, gender, and cultural origin. Resilience shifts the focus of psychological investigation onto increasing the positive rather than reducing the negative. Inquiry into resilience has evolved from descriptions of resilient qualities, to discovery of the process to attain resilience, to uncovering the motivation to reintegrate in a resilient manner. Much of the research on resilience has focused on children in settings such as family violence, extreme poverty, war, and natural disasters. A coherent pattern of characteristics associated with successful adaptation has emerged. Salient characteristics include commitment, dynamism, humor in the face of adversity, patience, optimism, faith, and altruism. As such, resilience may represent an important target of treatment in anxiety, depression, and stress reactions. Resilience can be quantified, but available measures need to be validated transculturally. There exist many possible determinants of resilience, including neurobiologic, genetic, temperament, and environmental influences. Resilience is modifiable on individual and cultural levels. Posttraumatic stress disorder is an example of a serious disorder associated with impaired stress coping that can improve with treatment.

International maternal mortality reduction: outcome of traditional birth attendant education and intervention in Angola.

BACKGROUND: As a result of war and periodic natural disasters, Angola has among the highest infant and maternal mortality rates in the world. In response to the acute health needs of the population, the International Medical Corps (IMC) developed a traditional birth attendant educational course designed to reduce the preventable causes of maternal and infant mortality. METHODS: From 1994 until 1998, Angolan traditional birth attendants (TBAs) participated in an intensive 38-hr training course on prenatal, delivery, and postnatal care. Following the birth of a child, the trained TBAs completed a registration form containing information regarding the health of the mother. Previous studies of Angolan maternal mortality served as historic comparisons. FINDINGS: Complete data including maternal mortality data were available for 19,666 deliveries (83% of total). Fifty five maternal deaths were recorded, which corresponds to a maternal mortality rate of 293 per 100,000 live births. The average historic maternal mortality rate for available comparison groups was 1241 per 100,000 live births. INTERPRETATION: The maternal mortality rate was reduced among women managed by IMC-trained TBAs when compared with historical control data.

Social attitudes toward traumatized men and women: a vignette study.

This study investigated social beliefs about gender-appropriate reactions to trauma. Ninety-three men and 179 women completed vignette measures of attitudes toward victims, the Bem Sex Role Inventory, and the Trauma History Questionnaire. Participants evaluated male victims less favorably than female victims. Women responded more positively toward all victims than men. Participants regarded female crime victims more positively than their male counterparts, but did not distinguish between male and female natural disaster victims. Feminine-sex-typed women rated victims more favorably than masculine-sex-typed individuals. There was a positive relation between personal trauma exposure and attitudes toward male victims among male participants. These findings contribute to an understanding of factors influencing the social reactions experienced by traumatized men and women, and have implications for clinical practice and psychoeducation.

Effects of the 1989 San Francisco earthquake on frequency and content of nightmares.

In a systematic evaluation of the effects of a natural disaster on nightmares, nightmare frequency was found to be about twice as high among 92 San Francisco Bay area college students as among 97 control subjects in Tucson, Arizona, after the 1989 Loma Prieta earthquake. Subjects in California had not only more nightmares in general but substantially more nightmares about earthquakes. Over a 3-week period, about 40% of those in the San Francisco Bay area reported one or more nightmares about an earthquake, as compared with only 5% of those in Arizona. However, nightmares about earthquakes were not more emotionally intense than other nightmares. These findings support the long-held view that the experience of a potentially traumatic event can result in more frequent nightmares, particularly about the event itself, but contradict the common opinion that nightmares about such events are unusually intense.

Prediction of posttraumatic stress symptoms in children after hurricane Andrew.

The authors used an integrative conceptual model to examine the emergence of posttraumatic stress disorder (PTSD) symptoms in 568 elementary school-age children 3 months after Hurricane Andrew. The model included 4 primary factors: Exposure to Traumatic Events, Child Characteristics, Access to Social Support, and Children's Coping. Overall, 62% of the variance in children's self-reported PTSD symptoms was accounted for by the 4 primary factors, and each factor improved overall prediction of symptoms when entered in the analyses in the order specified by the conceptual model. The findings suggest that the conceptual model may be helpful to organize research and intervention efforts in the wake of natural disasters.

Prewar factors in combat-related posttraumatic stress disorder: structural equation modeling with a national sample of female and male Vietnam veterans.

Structural equation modeling was used to examine relationships among prewar factors, dimensions of war-zone stress, and current posttraumatic stress disorder (PTSD) symptomatology using data from 1,632 female and male participants in the National Vietnam Veterans Readjustment Study. For men, previous trauma history (accidents, assaults, and natural disasters) directly predicted PTSD and also interacted with war-zone stressor level to exacerbate PTSD symptoms for high combat-exposed veterans. Male veterans who entered the war at a younger age displayed more symptoms. Family instability, childhood antisocial behavior, and age had indirect effects on PTSD for men. For women, indirect prewar effects emanated from family instability. More attention should be given to critical developmental conditions, especially family instability and earlier trauma exposure, in conceptualizing PTSD in adults.
