Introduction: When a large-scale disaster occurs, it is necessary to use the available resources in a variety of sites and scenes as efficiently as possible. To conduct such operations efficiently, it is necessary to deploy limited resources to the places where they will be the most effective. In this study, emergency and medical response activities that occurred following the Chuetsuoki Earthquake in Japan were analyzed to assess the most efficient and effective activities.

Methods: Records of patient transports by emergency services relating to the Niigata Chuetsuoki Earthquake, a magnitude 6.8 earthquake that struck Japan on 16 July 2007 were analyzed, and interview surveys were conducted.

Results: The occurrence of serious injuries caused by this earthquake essentially was limited to the day the earthquake struck. A total of 682 patients were treated on the day of the quake, of which about 90 were hospitalized. Of the 17 patients whose conditions were life-threatening, three were rescued and transported to hospital by firefighters, three were transported by ambulance, and 11 were transported to hospital using private means. Sixteen people were subsequently transferred to other hospitals, six of these by helicopter. There was difficulty in meeting all of the requests for emergency services within 4 to 6 hours of the earthquake’s occurrence. Most transports of patients whose conditions were life-threatening were between hospitals rather than from the scene of the injury. Transfers of critical patients between hospitals were efficient early on, but this does not necessarily mean that inter-hospital transfers were given higher priority than treatment at emergency scenes.

Conclusion: During the acute emergency period following a disaster-causing event, it is difficult to meet all requests for emergency services. In such cases, it is necessary to conduct efficient activities that target critically injured patients. Since hospital transfers are matters of great urgency, it is necessary to consider assigning resource investment priority to hospital transfers during this acute period, when ambulance services may be insufficient to meet all needs. To deal with such disasters appropriately, it is necessary to ensure effective information exchange and close collaboration between ambulance services, firefighting organizations, disaster medical assistance teams, and medical institutions.

Introduction: Celebrating the end of secondary schooling (“Schoolies Festival”) is an established part of the school culture in Australia, with thousands of young students converging at beachside locations to celebrate this rite of passage. The aim of this study was to identify what young people believe is important to remain safe and healthy at this mass-gathering event.

Methods: This study was conducted using postcard surveys requesting demographic data and responses to the questions: (1) What do you think is important to stay safe and healthy at this event?; (2) What do you think is risky attending this event?; (3) Which of these is most likely to affect you at this event?; and (4) Where would you seek medical support? The surveys were distributed to attendees of a “Schoolies Festival” in Adelaide, Australia in 2008.

Results: One hundred sixty-five of the 300 postcards were returned completed. The average age of the respondents was 17.7 years. “Not using drugs” was considered important to staying safe and healthy by 120 (73%) of respondents; “drinking alcohol responsibly” was considered important by 89 (54%); and “violent behavior” and “exposure to illicit drugs” were identified as important risks by 135 (82%) and 98 (59%) of participants, respectively. Only 35 (21%) of respondents indicated that they would seek on-site health care if needed.

Conclusion: Young people attending mass-gathering celebrations have valid concerns about drinking responsibly, exposure to illicit drugs, and sexual harassment. Health messages or health promotion strategies aimed at their specific concerns would be helpful in the mitigation of illness or injury at such events.

Introduction: The objective of this study was to investigate whether disaster exercises can be used as a proxy environment to evaluate potential research instruments designed to study the application of medical care management resources during a disaster.

Methods: During an 06 April 2005 Ministerial-level exercise in the Netherlands, three functional areas of patient contact were assessed: (1) Command and Control, through the application of an existing incident management system questionnaire; (2) patient flow and quality of patient distribution, through registration of data from prehospital casualty collection points, ambulances, and participating trauma centers (with inclusion of data in a flow chart); and (3) hospital coping capacity, through timed registration reports from participating trauma centers.

Results: The existing incident management system questionnaire used for evaluating Command and Control during a disaster exercise would benefit from minor adaptations and validation that could not be anticipated in the exercise planning stage. Patient flow and the quality of patient distribution could not be studied during the exercise because of inconsistencies among data, and lack of data from various collection points. Coping capacity was better measured by using 10-minute rather than one hour time intervals, but provided little information regarding bottlenecks in surge capacity.

Conclusion: Research instruments can be evaluated and improved when tested during a disaster exercise. Lack of data recovery hampers disaster research even in the artificial setting of a national disaster exercise. Providers at every level must be aware that proper data collection is essential to improve the quality of health care during a disaster, and that predisaster cooperation is crucial to validate patient outcomes. These problems must be addressed pre-exercise by stakeholders and decision-makers during planning, education, and training. If not, disaster exercises will not meet their full potential.

Background: High fidelity medical simulators (HFMS) are accepted tools for health care instruction. The use of HFMS was incorporated into an International Trauma Life Support course, and course participants were surveyed regarding attitudes toward HFMS.

Methods: Course participants, including physicians, nurses, and prehospital personnel, were given pre- and post-course questionnaires measuring their confidence in knowledge and treatment of trauma resuscitation, as well as their attitudes towards the utility and realism of immersive simulation. The participants were randomly assigned to take a course examination either before or after their simulator session.

Results: Thirteen course participants of varying backgrounds and degrees of clinical experience were surveyed and tested. All surveyed areas improved following simulator training, including comfort level with simulation as a training method (17%), perception of the realism of HFMS (15%), and reported self-confidence in knowledge, experience and training in trauma care (27%). Test scores were improved in the post-simulation group as opposed to the pre-simulation group (86% pass rate in the post-simulation test group versus 50% pass rate in the pre-simulation test group).

Conclusions: High fidelity medical simulation was accepted by medical professionals of different backgrounds and experience. Attitudes towards simulation and self-confidence improved after simulator sessions, as did test scores, suggesting improved comprehension and retention of course materials. Further testing is required to validate the findings of this small, observational study.

Introduction: Disaster Medicine is an increasingly important part of medicine. Emergency Medicine residency programs have very high curriculum commitments, and adding Disaster Medicine training to this busy schedule can be difficult. Development of a short Disaster Medicine curriculum that is effective and enjoyable for the participants may be a valuable addition to Emergency Medicine residency training.

Methods: A simulation-based curriculum was developed. The curriculum included four group exercises in which the participants developed a disaster plan for a simulated hospital. This was followed by a disaster simulation using the Disastermed.Ca Emergency Disaster Simulator computer software Version 3.5.2 (Disastermed.Ca, Edmonton, Alberta, Canada) and the disaster plan developed by the participants. Progress was assessed by a pre- and post-test, resident evaluations, faculty evaluation of Command and Control, and markers obtained from the Disastermed.Ca software.

Results: Twenty-five residents agreed to partake in the training curriculum. Seventeen completed the simulation. There was no statistically significant difference in pre- and post-test scores. Residents indicated that they felt the curriculum had been useful, and judged it to be preferable to a didactic curriculum. In addition, the residents’ confidence in their ability to manage a disaster increased on both a personal and and a departmental level.

Conclusions: A simulation-based model of Disaster Medicine training, requiring approximately eight hours of classroom time, was judged by Emergency Medicine residents to be a valuable component of their medical training, and increased their confidence in personal and departmental disaster management capabilities.

Introduction: In low-resource communities with long prehospital transport times, most trauma deaths occur outside the hospital. Previous studies from Iraq demonstrate that a two-tier network of rural paramedics with village-based first helpers reduces mortality in land mine and war-injured from 40% to 10%. However, these studies of prehospital trauma care in low-income countries have been conducted with historical controls, thus the results may be unreliable due to differences in study contexts. The aim of this study was to use a controlled study design to examine the effect of a two-tier prehospital rural trauma system on road traffic accident trauma mortality.

Methods: A single referral surgical hospital was the endpoint in a single-blinded, non-randomized cohort study. The catchment areas consisted of some districts with no formal Emergency Medical Services (EMS) system, and other districts where 95 health center paramedics had been trained and equipped to provide advanced life support, and 5,000 laypersons had been trained to give on-site first aid. The hospital staff registered trauma mortality and on-admission physiological severity blindly. Assuming that prehospital care would have no significant impact on mortality in moderate injuries, only road traffic accident (RTA) casualties with an Injury Severity Score (ISS) ≥9 were selected for study.

Results: During a three-month study period, 205 patients were selected for study (128 in the treatment group and 77 in the control group). The mean prehospital transit time was approximately two hours. The two groups were comparable with regards to demographic characteristics, distribution of wounds and injuries, and mean anatomical severity. The mortality rate was eight percent in the treatment group, compared to 44% in the control group (95% CI, 25%–48%). Adjusted for severity differences between the treatment and control groups, prehospital care was a significant contributor to survival.

Conclusion: Where prehospital transport time is long, a two-tier prehospital system of trained paramedics and layperson first responders reduces trauma mortality in severe RTA injuries. The findings may be valid for civilian Emergency Medical Services interventions in other low-resource countries.

Introduction: Out-of-hospital cardiac arrest (OHCA) is a lethal health problem that affects between 236,000 and 325,000 people in the United States each year. As resuscitation attempts are unsuccessful in 70-98% of OHCA cases, Emergency Medical Services (EMS) personnel often face the needs of bereaved family members.

Problem: Decisions to continue or terminate resuscitation at OHCA are influenced by factors other than patient clinical characteristics, such as EMS personnel’s knowledge, attitudes, and beliefs regarding family emotional preparedness. However, there is little research exploring how EMS personnel care for bereaved family members, or how they are affected by family dynamics and the emotional contexts. The aim of this study is to analyze EMS personnel’s experiences of caring for families when patients suffer cardiac arrest and sudden death.

Methods: The study is based on a hermeneutic lifeworld approach. Qualitative interviews were conducted with 10 EMS personnel from an EMS agency in southern Sweden.

Results: The EMS personnel interviewed felt responsible for both patient care and family care, and sometimes failed to prioritize these responsibilities as a result of their own perceptions, feelings and reactions. Moving from patient care to family care implied a movement from well-structured guidance to a situational response, where the personnel were forced to balance between interpretive reasoning and a more direct emotional response, at their own discretion. With such affective responses in decision-making, the personnel risked erroneous conclusions and care relationships with elements of dishonesty, misguided benevolence and false hopes. The ability to recognize and respond to people’s existential questions and needs was essential. It was dependent on the EMS personnel’s balance between closeness and distance, and on their courage in facing the emotional expressions of the families, as well as the personnel’s own vulnerability. The presence of family members placed great demands on mobility (moving from patient care to family care) in the decision-making process, invoking a need for ethical competence.

Conclusion: Ethical caring competence is needed in the care of bereaved family members to avoid additional suffering. Opportunities to reflect on these situations within a framework of care ethics, continuous moral education, and clinical ethics training are needed. Support in dealing with personal discomfort and clear guidelines on family support could benefit EMS personnel.

Introduction: In the prehospital care of a cold and wet person, early application of adequate insulation is of utmost importance to reduce cold stress, limit body core cooling, and prevent deterioration of the patient’s condition. Most prehospital guidelines on protection against cold recommend the removal of wet clothing prior to insulation, and some also recommend the use of a waterproof vapor barrier to reduce evaporative heat loss. However, there is little scientific evidence of the effectiveness of these measures.

Objective: Using a thermal manikin with wet clothing, this study was conducted to determine the effect of wet clothing removal or the addition of a vapor barrier on thermal insulation and evaporative heat loss using different amounts of insulation in both warm and cold ambient conditions.

Methods: A thermal manikin dressed in wet clothing was set up in accordance with the European Standard for assessing requirements of sleeping bags, modified for wet heat loss determination, and the climatic chamber was set to -15 degrees Celsius (°C) for cold conditions and +10°C for warm conditions. Three different insulation ensembles, one, two or seven woollen blankets, were chosen to provide different levels of insulation. Five different test conditions were evaluated for all three levels of insulation ensembles: (1) dry underwear; (2) dry underwear with a vapor barrier; (3) wet underwear; (4) wet underwear with a vapor barrier; and (5) no underwear. Dry and wet heat loss and thermal resistance were determined from continuous monitoring of ambient air temperature, manikin surface temperature, heat flux and evaporative mass loss rate.

Results: Independent of insulation thickness or ambient temperature, the removal of wet clothing or the addition of a vapor barrier resulted in a reduction in total heat loss of 19-42%. The absolute heat loss reduction was greater, however, and thus clinically more important in cold environments when little insulation is available. A similar reduction in total heat loss was also achieved by increasing the insulation from one to two blankets or from two to seven blankets.

Conclusion: Wet clothing removal or the addition of a vapor barrier effectively reduced evaporative heat loss and might thus be of great importance in prehospital rescue scenarios in cold environments with limited insulation available, such as in mass-casualty situations or during protracted evacuations in harsh conditions.

Introduction: Post-traumatic stress disorder (PTSD) is a common condition among Japanese firefighters. The purpose of this study was to clarify the relationship of PTSD scores to job stress, social support, and depressive stress among Japanese firefighters.

Methods: A total of 1,667 Japanese firefighters working for the local government completed a questionnaire that was used to gather information pertaining to age, gender, job type, job class, marital status, and smoking and drinking habits. Questionnaires from the Center for Epidemiologic Studies Depression Scale (CES-D), the Japanese version of the U.S. National Institute for Occupational Safety and Health (NIOSH) Generic Job Stress Questionnaire, and the IES-R were also used.

Results: After adjustment for age and gender, subjects in the PTSD-positive group had significantly higher scores for inter-group conflict, role ambiguity, and CES-D, as well as significantly lower scores for social support from their supervisors compared to those in the PTSD-negative group.

Conclusions: High inter-group conflict and role ambiguity, as well as low social support from supervisors and the presence of depressive symptoms, may influence the development of PTSD among Japanese firefighters.

Introduction: Research on prehospital emergency work traditionally has focused on medical issues, but paramedics often have to make ethical choices. The goal of this exploratory study was to understand how paramedics experience difficult ethical dilemmas regarding resuscitation of cancer patients.

Methods: Paramedics from ambulance services in Norway were interviewed about resuscitation of cancer patients with cardiac arrest. The qualitative study included naturalistic, semi-structured interviews and a cognitive-emotional, interpretive approach.

Results: All study participants believed that it ethically can be correct not to resuscitate if the patient is expected to survive for only a short time with a very low quality of life and severe negative illness experiences. However, this belief sometimes failed to match formal or informal guidelines and contextual factors such as expectations of relatives. When confronting these challenges, the majority of the paramedics relied heavily on the advice of medical experts, but some had to make more autonomous decisions.

Discussion: The concept of a double pressure situation can be used to analyze the ethical dilemmas regarding resuscitation of cancer patients. The pressure from “below” is grounded in individual caring frameworks, and in the belief that it can be wrong to resuscitate. The pressure from “above” is objective and system-related, related to uncertainty, and grounded in the fundamental and irreducible value of human life.

Conclusions: The findings of this qualitative, exploratory study suggest that ethical concepts and analyses of double pressure situations should have an important role in education and training designed to prepare emergency personnel for difficult life and death choices. More research is needed to shed light on how ethical dilemmas arise in prehospital work.

Objective: The objective of this study was to develop comprehensive guidelines for medical care during mass gatherings based on the experience of providing medical support during rave parties.

Methods: Study design was a prospective, observational study of self-referred patients who reported to First Aid Stations (FASs) during Dutch rave parties. All users of medical care were registered on an existing standard questionnaire. Health problems were categorized as medical, trauma, psychological, or miscellaneous. Severity was assessed based on the Emergency Severity Index. Qualified nurses, paramedics, and doctors conducted the study after training in the use of the study questionnaire. Total number of visitors was reported by type of event.

Results: During the 2006–2010 study period, 7,089 persons presented to FASs for medical aid during rave parties. Most of the problems (91.1%) were categorized as medical or trauma, and classified as mild. The most common medical complaints were general unwell-being, nausea, dizziness, and vomiting. Contusions, strains and sprains, wounds, lacerations, and blisters were the most common traumas. A small portion (2.4%) of the emergency aid was classified as moderate (professional medical care required), including two cases (0.03%) that were considered life-threatening. Hospital admission occurred in 2.2% of the patients. Fewer than half of all patients presenting for aid were transported by ambulance. More than a quarter of all cases (27.4%) were related to recreational drugs.

Conclusions: During a five-year field research period at rave dance parties, most presentations on-site for medical evaluation were for mild conditions. A medical team of six healthcare workers for every 10,000 rave party visitors is recommended. On-site medical staff should consist primarily of first aid providers, along with nurses who have event-specific training on advanced life support, event-specific injuries and incidents, health education related to self-care deficits, interventions for psychological distress, infection control, and disaster medicine. Protocols should be available for treating common injuries and other minor medical problems, and for registration, triage, environmental surveillance and catastrophe management and response.

Introduction The 2009 H1N1 influenza pandemic created a surge of patients with low-acuity influenza-like-illness (ILI) to hospital Emergency Departments (EDs). The development and results of a tiered surge plan to care for these patients at a Pediatric Emergency Department (PED) were studied.

Hypothesis/Problem By providing standard assessment and treatment algorithms within physically separate ILI Extension Areas, it was hypothesized that patient care could be streamlined and the quality of care maintained.

Methods Hospital administrators created the tiered H1N1 surge plan within the framework of the existing emergency operations plan (EOP). After the initial expansion of space and staff utilization within the existing PED footprint, ILI Extension Areas were opened and staffed by non-ED physicians and nursing to provide care rapidly for ILI patients after Registered Nurse (RN) screening. Volumes, length of stay (LOS), left without being seen (LWBS) rates, patient satisfaction, and costs were tracked and measured.

Results Significantly elevated volumes of patients were seen in the months of September and October of 2009 (42.0% and 32.7% increase over 2008). During this time, 612 patients were triaged to the ILI Extension Areas. The LOS was similar to that experienced in prior years. The LWBS rates in September (4.8%) and October (3.4%) were slightly elevated over the 2009 yearly average (3.2%), but remained lower than during a prior, high-volume month. Satisfaction, measured as patients’ “likelihood to recommend,” remained within the range observed during other parts of the year. Cost estimates indicate favorable financial performance for the institution.

Conclusion The tiered surge response plan represented a success in managing large volumes of low-acuity patients during an extended period of time. This design can be utilized effectively in the future during times of patient surge.

Introduction: In mass-casualty situations, communications and information management to improve situational awareness is a major challenge for responders. In this study, the feasibility of a prototype system that utilizes commercially available, low-cost components, including Radio Frequency Identification (RFID) and mobile phone technology, was tested in two simulated mass-casualty incidents.

Methods: The feasibility and the direct benefits of the system were evaluated in two simulated mass-casualty situations: one in Finland involving a passenger ship accident resulting in multiple drowning/hypothermia patients, and another at a major airport in Sweden using an aircraft crash scenario. Both simulations involved multiple agencies and functioned as test settings for comparing the disaster management’s situational awareness with and without using the RFID-based system. Triage documentation was done using both an RFID-based system, which automatically sent the data to the Medical Command, and a traditional method using paper triage tags. The situational awareness was measured by comparing the availability of up-to date information at different points in the care chain using both systems.

Results: Information regarding the numbers and status or triage classification of the casualties was available approximately one hour earlier using the RFID system compared to the data obtained using the traditional method.

Conclusions: The tested prototype system was quick, stable, and easy to use, and proved to work seamlessly even in harsh field conditions. It surpassed the paper-based system in all respects except simplicity of use. It also improved the general view of the mass-casualty situations, and enhanced medical emergency readiness in a multi-organizational medical setting. The tested technology is feasible in a mass-casualty incident; further development and testing should take place.

A 20-year-old male was impaled through the chest, abdomen, and right upper thigh by three 1.5 cm (0.59 in) diameter rods, each 2 m (6.56 ft) in length. The first rod entered below his right nipple, the second through the right hypochondrium, and the third through the right upper thigh. He was transported to the hospital with the rods in situ. This paper provides insight as to how these unusual injuries were managed in a limited-resource environment. Even in a developing country, the challenges posed by multiple impalement injuries can be managed successfully by rapid prehospital transfer, along with an adequate and coordinated hospital team effort.

The number of reported natural disasters is increasing, as is the number of foreign medical teams (FMTs) sent to provide relief. Studies show that FMTs are not coordinated, nor are they adapted to the medical needs of victims. Another key challenge to the response has been the lack of common terminologies, definitions, and frameworks for FMTs following disasters.

In this report, a conceptual health system framework that captures two essential components of health care response by FMTs after earthquakes is presented. This framework was developed using expert panels and personal experience, as well as an exhaustive literature review.

The framework can facilitate decisions for deployment of FMTs, as well as facilitate coordination in disaster-affected countries. It also can be an important tool for registering agencies that send FMTs to sudden onset disasters, and ultimately for improving disaster response.

Background: According to US military data, tension pneumothorax (TPx) is the second leading cause of possibly preventable combat death after isolated extremity hemorrhage. The purpose of this study was to determine whether TPx similarly represents a significant cause of possibly preventable death in police officers.

Methods: FBI data for the years 1998 through 2007 were reviewed. Cases were included if officers were on-duty at the time of fatal injury, and died within one hour from time of wounding from penetrating torso trauma. After case identification, letters were sent to the departments of victim officers requesting autopsy reports.

Results: One hundred and eight victim officers met inclusion criteria. Four charts were excluded due to inability to re-identify officers. Departmental response rate was 83.7%. Autopsy reports were provided for 60 officers (57.7%). All officers died from gunshot wounds. No coroner specifically identified TPx as either a direct cause of death or a contributing factor (95% CI, 0.00%-5.96%).

Conclusion: In contrast to the military experience, TPx appears to be a rare cause of possibly preventable death in police officers. Further study of non-fatal “near miss” events will be required to determine the actual need for law enforcement-specific medical training in the recognition and management of TPx.

Background: The state of Oklahoma, known for destructive tornados, has a native Spanish-speaking (NSS) population of approximately 180,241, of which 50% report being able to speak English “very well” (US Census Bureau). With almost 50% of these native Spanish-speaking persons being limited English proficient (LEP), their reception of tornado hazard communications may be restricted. This study conducted in northeast Oklahoma (USA) evaluates the association between native language and receiving tornado hazard communications.

Methods: This study was a cross-sectional survey conducted among a convenience sample of NSS and native English-speaking (NES) adults at Xavier Clinic and St. Francis Trauma Emergency Center in Tulsa, OK, USA from September 2009 through December 2009. Of the 82 surveys administered, 80 were returned, with 40 NES and 40 NSS participants. A scoring system (Severe Weather Information Reception (SWIR)) was developed to quantify reception of hazard information among the study participants (1–3 points = poor reception, 4–5 = adequate reception, 6–8 = excellent reception). Pearson’s chi-squared test was used to calculate differences between groups with Yates’ continuity correction applied where appropriate, and SWIR scores were analyzed using ANOVA. P-values <.05 were considered significant.

Results: NSS fluency in English was 25.6%. No significant association was found between native language and those who watch television, listen to radio, have a National Oceanic and Atmospheric Administration (NOAA) All Hazards radio or telephone, or are in audible range of a tornado siren. NSS were less likely to have Internet access (P < .004), and less likely to know of local telephone warning programs (P < .03). The mean NSS SWIR score was 3.2 (95% CI, 2.8-3.7) while LEP NSS averaged 2.8 (95% CI, 2.4-3.2). The mean NES SWIR score was 4.5 (95% CI, 4.1-5.0).

Conclusion: Results demonstrate a disparity in tornado warning reception between NSS and NES. Poor English proficiency was noted to be 75% among NSS, which is approximately 25% more than estimated by the US Census Bureau. This study demonstrates a need for emergency managers to recognize when appropriate and overcome communication disparities among limited English proficient populations.

The current study presents a pilot demonstration of a new therapeutic procedure to mitigate symptoms of post-traumatic stress disorder (PTSD). The pilot took place during the Second Lebanon War. Vulnerability and resilience statements, as well as post-traumatic symptoms, were measured among special army administrative staff (SAAS) who worked in a hospital setting during extreme and prolonged war stress. All 13 soldiers in the unit studied participated in seven group therapy intervention sessions. It was hypothesized that shifting the focus of therapeutic intervention from the scenes of the events to the personal and professional narratives of preparing for the event would change the content of the soldiers’ narratives. It was believed that subtracting the number of positive statements from the number of negative statements would yield increasingly higher “resilience scores” during and after the war. It also was believed that such a change would be reflected in reduction of post-traumatic symptoms. As expected, the participants showed a decrease in vulnerability and an increase in resilience contents, as well as a decrease in traumatic symptoms during and after the war. These findings may reflect the effects of the ceasefire, the mutually supportive attitude of the participants, and the therapeutic interventions.
