The elderly population has proven to be vulnerable in times of a disaster. Many have chronic medical problems for which they depend on medications or medical equipment. Some older adults are dependent on caregivers for managing their activities of daily living (ADLs), such as dressing, and their instrumental activities of daily living (IADLs), such as transportation.
Problem
A coordinated effort for disaster preparation in the elderly population is paramount. This study assessed the potential needs and plans of older adults in the face of a local disaster.
Methods
The setting was a community-based, university-affiliated, urban emergency department (ED) that sees more than 77,000 adult patients per year. A survey on disaster plans and resources needed if evacuated was distributed to 100 community-residing ED patients and visitors aged 65 years and older from January through July 2013. Means and proportions are reported with 95% confidence intervals (CIs).
Results
Data were collected from 13 visitors and 87 patients. The mean age was 76 years, and 54% were female. Thirty-one responded that they had a disaster plan in place (31/100; CI, 22.4-41.4%). Of those 31, 94% (29/31; CI, 78.6-99.2%) had food and water as part of their plan, 62% (19/29; CI, 42.2-78.2%) had a supply of medication, and 35% (12/31; CI, 21.8-57.8%) had an evacuation plan. When asked what supplies the 100 subjects might need if evacuated, 33% (CI, 23.9-43.1%) needed a walker, 15% (CI, 8.6-23.5%) needed a wheelchair, 78% (CI, 68.6-85.7%) needed glasses, 17% (CI, 10.2-25.8%) needed a hearing aid, 16% (CI, 9.4-24.7%) needed a glucometer, 93% (CI, 86.1-97.1%) needed medication, 14% (CI, 7.8-22.4%) needed oxygen, 23% (CI, 15.2-32.5%) needed adult diapers, and 21% (CI, 13.2-30.3%) had medical equipment that required electricity. Many of the subjects also required help with one or more of their ADLS, the most common being dressing (17%; CI, 10.3-26.1%), or their IADLS, the most common being transportation (39%; CI, 29.7-49.7%). Only 42% (CI, 32.3-52.7%) were interested in learning more about disaster preparation.
Conclusion
Only a minority of the older adults in the study population had a disaster plan in place. Most of the respondents would require medications, and many would require medical supplies if evacuated.
Using the pediatric version of the Simple Triage and Rapid Treatment (JumpSTART) algorithm for the triage of pediatric patients in a mass-casualty incident (MCI) requires assessing the results of each step and determining whether to move to the next appropriate action. Inappropriate application can lead to performance of unnecessary actions or failure to perform necessary actions.
Hypothesis/Problem
To report overall accuracy and time required for triage, and to assess if the performance of unnecessary steps, or failure to perform required steps, in the triage algorithm was associated with inaccuracy of triage designation or increased time to reach a triage decision.
Methods
Medical students participated in an MCI drill in which they triaged both live actors portraying patients and computer-based simulated patients to the four triage levels: minor, delayed, immediate, and expectant. Their performance was timed and compared to intended triage designations and a priori determined critical actions.
Results
Thirty-three students completed 363 scenarios. The overall accuracy was 85.7% and overall mean time to assign a triage designation was 70.4 seconds, with decreasing times as triage acuity level decreased. In over one-half of cases, the student omitted at least one action and/or performed at least one action that was not required. Each unnecessary action increased time to triage by a mean of 8.4 seconds and each omitted action increased time to triage by a mean of 5.5 seconds.
Discussion
Increasing triage level, performance of inappropriate actions, and omission of recommended actions were all associated with increasing time to perform triage.

In the course of their duties, firefighters risk heat stroke and other medical conditions due to exertion in high-temperature environments. Infrared tympanic temperature measurement (TTym) is often used by Emergency Medical Services (EMS) to assess the core body temperature of firefighters. The accuracy of TTym in this setting has been called into question.
Hypothesis/Problem
This study aimed to examine the accuracy of TTym for core body temperature assessment at emergency firefighting events compared with gastrointestinal temperature measurement (TGI) as measured by ingestible thermometers.
Methods
Forty-five (42 male, three female) professional urban firefighters from an Australian fire service completed two 20-minute work periods in a 100°C (± 5°C) heat chamber while wearing personal protective clothing (PPC) and breathing apparatus (weighing approximately 22 kg). Measurements were taken immediately before entering, and on exiting, the heat chamber. Tympanic temperature was assessed by an infrared tympanic thermometer and TGI was measured by ingestible sensor and radio receiver.
Results
Complete data were available for 37 participants. Participant temperatures were higher on exiting the heat chamber than at baseline (TTym: 35.9°C (SD=0.7) vs 37.5°C (SD=0.8); TGI: 37.2°C (SD=0.4) vs 38.6°C (SD=0.5)). Tympanic temperature underestimated TGI on average by 1.3°C (SD=0.5) before entering the chamber and by 1.0°C (SD=0.8) following the exercise. Using pooled data, the average underestimation was 1.2°C (SD=0.7).
Conclusion
Tympanic thermometers cause an unreliable measure of core body temperature for firefighters engaged in fire suppression activities. Accurate and practical measures of core body temperature are required urgently.

During July through August 2014, Operation Protective Edge, a military conflict between Israel and the Hamas regime in Gaza, dramatically affected both populations. Magen David Adom (MDA), the Israeli national Emergency Medical Service (EMS) and a member of the Red Cross, faced a unique challenge during the conflict: to continue providing crucial service to the entire civilian population of Israel, which was under constant missile threat. This challenge included not only providing immediate care for routine EMS calls under missile threat, but also preparing and delivering immediate care to civilians injured in attacks on major cities, as well as small communities, in Israel. This task is a challenge for a civilian EMS agency that normally operates in a non-military environment, yet, in an instant, must enhance its capability to respond to a considerable threat to its population. During Operation Protective Edge, MDA provided care for 842 wounded civilians and utilized a significant amount of its resources. Providing EMS services for a civilian population in a mixed civilian/military scenario is a challenging task on a national level for an EMS system, especially when the threat lasts for weeks. This report describes MDA’s preparedness and operations during Operation Protective Edge, and the unique EMS challenges and dilemmas the agency faced.

Mass-casualty incidents (MCIs) present a unique challenge with regards to triage as patient volume often outweighs the number of available Emergency Medical Services (EMS) providers. A possible strategy to optimize existing triage systems includes the use of other first responder groups, namely fire and police, to decrease the triage time during MCIs, allowing for more rapid initiation of life-saving treatment and prioritization of patient transport.
Hypothesis
First-year primary care paramedic (PCP), fire, and police trainees can apply with similar accuracy an internationally recognized MCI triage tool, Sort, Assess, Life-saving interventions, Treatment/transport (SALT), immediately following a brief training session, and again three months later.
Methods
All students enrolled in the PCP, fire, and police foundation programs at two community colleges were invited to participate in a 30-minute didactic session on SALT. Immediately following this session, a 17-item, paper-based test was administered to assess the students’ ability to understand and apply SALT. Three months later, the same test was given to assess knowledge retention.
Results
Of the 464 trainees who completed the initial test, 364 (78.4%) completed the three month follow-up test. Initial test scores were higher (P<.05) for PCPs (87.0%) compared to fire (80.2%) and police (68.0%) trainees. The mean test score for all respondents was higher following the initial didactic session compared to the three month follow-up test (75% vs 64.7%; Δ 10.3%; 95% CI, 8.0%-12.6%). Three month test scores for PCPs (75.4%) were similar to fire (71.4%) students (Δ 4.0%; 95% CI, −2.1% to 10.1%). Both PCP and fire trainees significantly outperformed police (57.8%) trainees. Over-triage errors were the most common, followed by under-triage and then critical errors, for both the initial and follow-up tests.
Conclusions
Amongst first responder trainees, PCPs were able to apply the SALT triage tool with the most accuracy, followed by fire, then police. Over-triage was the most frequent error, while critical errors were rare.

Massive hemorrhage with coagulopathy is one of the leading causes of preventable death in the battlefield. The development of freeze-dried plasma (FDP) allows for early treatment with coagulation-optimizing resuscitation fluid in the prehospital setting. This report describes the first prehospital use of FDP in a patient with carotid artery injury due to a high-velocity gunshot wound (HVGSW) to the neck. It also describes in-flight constitution and administration of FDP in a Medevac Helicopter. Early administration of FDP may contribute to hemodynamic stabilization and reduction in trauma-induced coagulopathy and acidosis. However, large-scale studies are needed to define the prehospital use of FDP and other blood products.

Violent patients in the prehospital environment pose a threat to health care workers tasked with managing their medical conditions. While research has focused on methods to control the agitated patient in the emergency department (ED), there is a paucity of data looking at the optimal approach to subdue these patients safely in the prehospital setting.
Hypothesis
This study evaluated the efficacy of two different intramuscular medications, midazolam and haloperidol, to determine their efficacy in sedating agitated patients in the prehospital setting.
Methods
This was a prospective, randomized, observational trial wherein agitated patients were administered intramuscular haloperidol or intramuscular midazolam to control agitation. Agitation was quantified by the Richmond Agitation and Sedation Scale (RASS). Paramedics recorded the RASS and vital signs every five minutes during transport and again upon arrival to the ED. The primary outcome was mean time to achieve a RASS less than +1. Secondary outcomes included mean time for patients to return to baseline mental status and adverse events.
Results
Five patients were enrolled in each study group. In the haloperidol group, the mean time to achieve a RASS score of less than +1 was 24.8 minutes (95% CI, 8-49 minutes), and the mean time for the return of a normal mental status was 84 minutes (95% CI, 0-202 minutes). Two patients required additional prehospital doses for adequate sedation. There were no adverse events recorded in the patients administered haloperidol.
In the midazolam group, the mean time to achieve a RASS score of less than +1 was 13.5 minutes (95% CI, 8-19 minutes) and the mean time for the return of normal mental status was 105 minutes (95% CI, 0-178 minutes). One patient required additional sedation in the ED. There were no adverse events recorded among the patients administered midazolam.
Conclusions
Midazolam and haloperidol administered intramuscularly appear equally effective for sedating an agitated patient in the prehospital setting. Midazolam appears to have a faster onset of action, as evidenced by the shorter time required to achieve a RASS score of less than +1 in the patients who received midazolam. Haloperidol offers an alternative option for the sedation of an agitated patient. Further studies should focus on continued investigation into appropriate sedation of agitated patients in the prehospital setting.

Little is known about the overall frequency of hazardous materials (HazMat) events in the United States and the nature of prehospital care for those exposed. The purpose of the current study was to perform a descriptive analysis of Emergency Medical Services (EMS) activations reported to a national EMS database.
Methods
Analysis of the 2012 National EMS Information System (NEMSIS) Public Release Research Data Set v.2.2.1, containing EMS emergency response data submitted by 41 states, was conducted. Mandatory data elements E0207 (Type of Response Delay), E0208 (Type of Scene Delay), and E0209 (Type of Transport Delay) contained specific codes for HazMat events and were used to identify specific EMS activation records for subsequent analysis. Overlapping data elements were identified and combined in order to prevent duplicate entries. Descriptive analyses were generated from the NEMSIS Research Data Set.
Results
A total of 17,479,328 EMS activations were reported, of which 2,527 unique activations involved HazMat response. Mass-casualty incident was coded for 5.6% of activations. The most common level of prehospital care present on scene was Basic Life Support (BLS; 51.1%); 2.1% required aggressive Advanced Life Support (ALS) response. The most common locations for HazMat activations were homes (36.2%), streets or highways (26.3%), and health care facilities (11.6%). The primary symptoms observed by EMS personnel were pain (29.6%), breathing problems (12.2%), and change in responsiveness (9.6%). Two percent of HazMat activations involved cardiac arrest, with 21.7% occurring after EMS arrival. Delays in patient care included response delay, scene delay, and transport delay.
Conclusion
Hazardous materials events are rare causes of EMS activation in the United States. The majority occur in non-industrial venues and involve two or fewer patients. Scene time frequently is delayed due to multiple barriers. Cardiac arrest is rare but occurred after EMS arrival in one-fifth of patients.

Orthopedic injuries commonly affect children during earthquakes, but reports about them are rare. This setting may lead to different standards of care, but guidelines are still missing in this field. A systematic review was performed to: (1) assess type and body distribution of pediatric earthquake-related injuries, treatment performed, length of stay, and complications; and (2) identify starting points to define standards of care.
PubMed database was researched for papers (1999-2014 period) in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Inclusion criteria were: English, French, Spanish, or Italian language and data reported about orthopedic lesions in children (≤18 years old). Reviews, letters, commentaries, editorials, and single case reports were excluded. Two independent reviewers selected articles after abstract and full-text reading.
Traumatic injuries caused child hospital admissions ranging from 46.9% to 100.0%; 16% to 53% suffered fractures. Lower limbs mostly were involved. Soft-tissue injuries affected 55% of patients. Debridement and external fixation (EF) were the most frequent surgical treatments. Amputation rates varied from 5% to 11%.
This study revealed that field hospitals should be prepared to: (1) treat mainly lower extremities fractures in children; and (2) use especially EF techniques. The presence of orthopedic surgeons familiar with pediatric traumatology should be considered.

Recent studies have brought to question the efficacy of the use of prehospital therapeutic hypothermia for victims of out-of-hospital cardiac arrest (OHCA). Though guidelines recommend therapeutic hypothermia as a critical link in the chain of survival, the safety of this intervention, with the possibility of minimal treatment benefit, becomes important.
Hypothesis/Problem
This study examined prehospital therapeutic hypothermia for OHCA, its association with survival, and its complication profile in a large, metropolitan, fire-based Emergency Medical Services (EMS) system, where bystander cardiopulmonary resuscitation (CPR) and post-arrest care are in the process of being optimized.
Methods
This evaluation was a retrospective chart review of all OHCA patients with return of spontaneous circulation (ROSC) treated with therapeutic hypothermia, from January 1, 2013 through November 30, 2013. The primary outcomes were the proportion of patients with initiation of prehospital therapeutic hypothermia with survival to hospital admission, the proportion of patients with initiation of prehospital therapeutic hypothermia with survival to hospital discharge, and the complication profile of therapeutic hypothermia in this population. The complication profile included several clinical, radiographic, and laboratory parameters. Exclusion criteria included: no prehospital therapeutic hypothermia initiation; no ROSC; and age of 17 year old or younger.
Results
Fifty-one post-cardiac arrest patients were identified that met inclusion criteria. The mean age was 61 years (SD=14.7 years), and 33 (72%) were male. The initial rhythm was ventricular fibrillation or pulseless ventricular tachycardia in 17 (37%) patients, and bystander CPR was performed in 28 (61%) patients with ROSC. Thirty-nine (85%) patients survived to hospital admission. Twenty-one patients (48%; 95% CI, 33-64) were administered vasopressors, 10 patients (24%; 95% CI, 10-37) were administered diuretics, and 19 patients (44%; 95% CI, 29-60) were administered antibiotics. Initial chest radiograph (CXR) findings were normal in 12 (29%) patients. Overall, 13 (28%; 95% CI, 15-42) study patients survived to hospital discharge.
Conclusion
Recent reports have questioned the efficacy and safety of prehospital therapeutic hypothermia. In this evaluation, in the setting of unstandardized post-arrest care, 85% of the patients survived to hospital admission and 28% survived to hospital discharge, with a complication profile which was similar to that noted in other studies. This suggests that further evidence may be needed before EMS systems stop administering therapeutic hypothermia to appropriately selected patients. In less-optimized systems, therapeutic hypothermia may still be an essential link in the chain of survival.

Multiple modalities for simulating mass-casualty scenarios exist; however, the ideal modality for education and drilling of mass-casualty incident (MCI) triage is not established.
Hypothesis/Problem
Medical student triage accuracy and time to triage for computer-based simulated victims and live moulaged actors using the pediatric version of the Simple Triage and Rapid Treatment (JumpSTART) mass-casualty triage tool were compared, anticipating that student performance and experience would be equivalent.
Methods
The victim scenarios were created from actual trauma records from pediatric high-mechanism trauma presenting to a participating Level 1 trauma center. The student-reported fidelity of the two modalities was also measured. Comparisons were done using nonparametric statistics and regression analysis using generalized estimating equations.
Results
Thirty-three students triaged four live patients and seven computerized patients representing a spectrum of minor, immediate, delayed, and expectant victims. Of the live simulated patients, 92.4% were given accurate triage designations versus 81.8% for the computerized scenarios (P=.005). The median time to triage of live actors was 57 seconds (IQR=45-66) versus 80 seconds (IQR=58-106) for the computerized patients (P<.0001). The moulaged actors were felt to offer a more realistic encounter by 88% of the participants, with a higher associated stress level.
Conclusion
While potentially easier and more convenient to accomplish, computerized scenarios offered less fidelity than live moulaged actors for the purposes of MCI drilling. Medical students triaged live actors more accurately and more quickly than victims shown in a computerized simulation.

Although it is well known that the Great East Japan Earthquake (March 11, 2011) resulted in a large number of disaster-related deaths, it is not common knowledge that the number of disaster-related deaths continues to increase, even four years after the earthquake, in Fukushima Prefecture, where the nuclear power plant accident occurred. There has been a lack of a minute and critical analysis for the causes for this continuous increase. In this report, the causes for the increase in disaster-related deaths in Fukushima Prefecture were analyzed by aggregating and comparing multiple data released by public organizations (the Reconstruction Agency, the National Police Agency, and Fukushima Prefecture), which may also have implications for developing response strategies to other disasters. The disaster-related death rate, the dead or missing rate, and the refugee rate (the number of disaster-related deaths, dead or missing persons, and refugees per 1,000 people) in each prefecture in stricken areas, and also each city, county, town, and village in Fukushima Prefecture, were calculated and compared with each other. The populations which were used for the calculation of each death rate in the area were based on the number of dead victims who had lived in the area when the earthquake occurred, regardless of where they were at the time of their death. The disaster-related death rate was higher than the dead or missing rate in the area around a stricken nuclear power plant in Fukushima Prefecture. These areas coincide exactly with the Areas under Evacuation Orders because of unsafe radiation levels. The external and internal radiation doses of most of the victims of the Great East Japan Earthquake have appeared not to be so high to harm their health, until now. The psychological stress associated with being displaced from one’s home for a long time with an uncertain future may be the cause for these disaster-related deaths. There is an urgent need to recognize refugees’ stressful situations, which could even cause death, and to provide them with high-quality medical treatment, including care for their long-term mental health.

Community Assessment for Public Health Emergency Response (CASPER) is an epidemiologic technique designed to provide quick, inexpensive, accurate, and reliable household-based public health information about a community’s emergency response needs. The Health Studies Branch at the Centers for Disease Control and Prevention (CDC) provides in-field assistance and technical support to state, local, tribal, and territorial (SLTT) health departments in conducting CASPERs during a disaster response and in non-emergency settings. Data from CASPERs conducted from 2003 through 2012 were reviewed to describe uses of CASPER, ascertain strengths of the CASPER methodology, and highlight significant findings.
Methods
Through an assessment of the CDC’s CASPER metadatabase, all CASPERs that involved CDC support performed in US states and territories from 2003 through 2012 were reviewed and compared descriptively for differences in geographic distribution, sampling methodology, mapping tool, assessment settings, and result and action taken by decision makers.
Results
For the study period, 53 CASPERs were conducted in 13 states and one US territory. Among the 53 CASPERS, 38 (71.6%) used the traditional 2-stage cluster sampling methodology, 10 (18.8%) used a 3-stage cluster sampling, and two (3.7%) used a simple random sampling methodology. Among the CASPERs, 37 (69.9%) were conducted in response to specific natural or human-induced disasters, including 14 (37.8%) for hurricanes. The remaining 16 (30.1%) CASPERS were conducted in non-disaster settings to assess household preparedness levels or potential effects of a proposed plan or program. The most common recommendations resulting from a disaster-related CASPER were to educate the community on available resources (27; 72.9%) and provide services (18; 48.6%) such as debris removals and refills of medications. In preparedness CASPERs, the most common recommendations were to educate the community in disaster preparedness (5; 31.2%) and to revise or improve preparedness plans (5; 31.2%). Twenty-five (47.1%) CASPERs documented on the report or publications the public health action has taken based on the result or recommendations. Findings from 27 (50.9%) of the CASPERs conducted with CDC assistance were published in peer-reviewed journals or elsewhere.
Conclusion
The number of CASPERs conducted with CDC assistance has increased and diversified over the past decade. The CASPERs’ results and recommendations supported the public health decisions that benefitted the community. Overall, the findings suggest that the CASPER is a useful tool for collecting household-level disaster preparedness and response data and generating information to support public health action.

Critical care transport (CCT) teams must manage a wide array of medications before and during transport. Appreciating the medications required for transport impacts formulary development as well as staff education and training.
Problem
As there are few data describing the patterns of medication administration, this study quantifies medication administrations and patterns in a series of adult CCTs.
Methods
This was a retrospective review of medication administration during CCTs of patients with severe hypoxemic respiratory failure from October 2009 through December 2012 from referring hospitals to three tertiary care hospitals.
Results
Two hundred thirty-nine charts were identified for review. Medications were administered by the CCT team to 98.7% of these patients, with only three patients not receiving any medications from the team. Fifty-nine medications were administered in total with 996 instances of administration. Fifteen drugs were each administered to only one patient. The mean number of medications per patient was 4.2 (SD=1.8) with a mean of 1.9 (SD=1.1) drug infusions per patient.
Conclusions
These results demonstrate that, even within a relatively homogeneous population of patients transferred with hypoxemic respiratory failure, a wide range of medications were administered. The CCT teams frequently initiated, titrated, and discontinued continuous infusions, in addition to providing numerous doses of bolused medications.

The use of prehospital needle thoracostomy (NT) is controversial. Some studies support its use; however, concerns exist regarding misplacement, inappropriate patient selection, and iatrogenic injury. Even less is known about its efficacy in situations where there is a delay to definitive care.
Hypothesis/Aim
To determine any differences in survival of patients who underwent NT in the setting of prolonged versus short transport times, and to describe differences in mechanisms and complications between the two groups.
Methods
This was a retrospective, matched, case-control study of trauma patients in a four county Emergency Medical Service (EMS) system from April 1, 2007 through April 1, 2013. This system serves an urban, rural, and wilderness catchment area. A prehospital database was queried for all patients in whom NT was performed, identifying 182 patients. When these calls were limited to those with prolonged transport times, the search was narrowed to 32 cases. A matched control group, based on age and gender, with short transport times was then created as a comparison. Data collected from prehospital and hospital records included: demographics; mechanism of injury; call status; response to NT; and final outcome. Univariate and multivariate analyses were conducted, as appropriate, to assess the primary outcome of survival and to further elucidate the descriptive data.
Results
There was no difference in survival between the case and control groups, either when evaluated with univariate (34% vs 25%; P=.41) or multivariate (odds ratio=0.99; 95% CI, 0.96-1.02; P=.57) analyses. Blunt trauma was the most common mechanism in both groups, but penetrating trauma was more common in the control group (30% vs 9%; P=.003). Patients in the control group were also more likely to have no vital signs on initial assessment (62% vs 31%; P=.003). More patients in the case group were described as having clinical improvement after NT (34% vs 19%; P=.03). No complications of NT were reported in either group.
Conclusions
There was no significant difference in survival between patients with prolonged versus short transport times who underwent NT. Patients with prolonged transport times were more likely to have sustained blunt trauma, have vital signs on EMS arrival, and to have clinical improvement after NT.

The effect on behavioral change of educational programs developed to reduce the community’s disaster informational vulnerability is not known. This study describes the relationship of disaster education, age, sex, and country-specific characteristics with students discussing disasters with friends and family, a measure of proactive behavioral change in disaster preparedness.
Methods
Three thousand eight hundred twenty-nine final year high school students were enrolled in an international, multi-center prospective, cross-sectional study using a pre-validated written questionnaire. In order to obtain information from different educational systems, from countries with different risk of exposure to disasters, and from countries with varied economic development status, students from Bahrain, Croatia, Cyprus, Egypt, Greece, Italy, Portugal, Romania, and Timor-Leste were surveyed. Logistic regression analyses examined the relationship between the likelihood of discussing disasters with friends and family (dependent variable) and a series of independent variables (age, gender, participation in school lessons about disasters, existence of a national disaster educational program, ability to list pertinent example of disasters, country's economic group, and disaster risk index) captured by the questionnaire or available as published data.
Results
There was no statistically significant relationship between age, awareness of one’s surroundings, planning for the future, and foreseeing consequences of events with discussions about potential hazards and risks with friends and/or family. The national educational budget did not have a statistically significant influence. Participants who lived in a low disaster risk and high income Organization for Economic Co-operation and Development (OECD) country were more likely to discuss disasters. While either school lessons or a national disaster education program had a unique, significant contribution to the model, neither had a better predictive utility.
Conclusions
The predictors (national disaster program, school lessons, gender, ability to list examples of disasters, country’s disaster risk index, and level of economic development), although significant, were not sufficient in predicting disaster discussions amongst teenagers.

In late October of 2012, Hurricane Sandy struck the northeast United States and shelters were established throughout the impacted region. Numerous cases of infectious viral gastroenteritis occurred in several of these shelters. Such outbreaks are common and have been well described in the past. Early monitoring for, and recognition of, the outbreak allowed for implementation of aggressive infection control measures. However, these measures required intensive medical response team involvement. Little is known about how such outbreaks affect the medical teams responding to the incident.
Hypothesis/Problem
Describe the impact of an infectious viral gastroenteritis outbreak within a single shelter on a responding medical team.
Methods
The number of individuals staying in the single shelter each night (as determined by shelter staff) and the number of patients treated for symptoms of viral gastroenteritis were recorded each day. On return from deployment, members of a single responding medical team were surveyed to determine how many team members became ill during, or immediately following, their deployment.
Results
The shelter population peaked on November 5, 2012 with 811 individuals sleeping in the shelter. The first patients presented to the shelter clinic with symptoms of viral gastroenteritis on November 4, 2012, and the last case was seen on November 21, 2012. A total of 64 patients were treated for nausea, vomiting, or diarrhea over the 17-day period. A post-deployment survey was sent to 66 deployed medical team members and 45 completed the survey. Twelve (26.7%) of the team members who responded to the survey experienced symptoms of probable viral gastroenteritis. Team members reported onset of symptoms during deployment as well as after returning home. Symptoms started on days 4-8, 8-14, on the trip home, and after returning home in four, four, two, and two team members, respectively.
Conclusion
Medical teams providing shelter care during viral gastroenteritis outbreaks are susceptible to contracting the virus while caring for patients. When responding to similar incidents in the future, teams should not only be ready to implement aggressive infectious control measures but also be prepared to care for team members who become ill.
