The aim of this study was to evaluate whether bystanders with no training in triage can correctly prioritize three injured patients by using a triage instrument.
Method
An observational study was conducted. Participants performed a primary triage on three paper-based patient cases and answered 11 questions during a public event in the center of Stockholm, Sweden.
Results
A total of 69 persons participated in the study. The success rate among all the participants for correct triage of the three patient cases was 52 percent. The female participants and younger participants (<55 years of age) performed correct triage to a greater extent. The over-triage was 12.5 percent and under-triage was 6.3 percent.
Conclusion
Participants with no prior knowledge of triage instruments may be capable of triaging injured patients with the help of an easy triage instrument. The over- and under-triage percentages were low, and this may indicate that the developed triage instrument is relatively easy to use. It may also indicate that bystanders can identify a severely injured patient.

Though the US civilian trauma care system plays a critical role in disaster response, there is currently no systems-based strategy that enables hospital emergency management and local and regional emergency planners to quantify, and potentially prepare for, surges in trauma care demand that accompany mass-casualty disasters.
Objective
A proof-of-concept model that estimates the geographic distributions of patients, trauma center resource usage, and mortality rates for varying disaster sizes, in and around the 25 largest US cities, is presented. The model was designed to be scalable, and its inputs can be modified depending on the planning assumptions of different locales and for different types of mass-casualty events.
Methods
To demonstrate the model’s potential application to real-life planning scenarios, sample disaster responses for 25 major US cities were investigated using a hybrid of geographic information systems and dynamic simulation-optimization. In each city, a simulated, fast-onset disaster epicenter, such as might occur with a bombing, was located randomly within one mile of its population center. Patients then were assigned and transported, in simulation, via the new model to Level 1, 2, and 3 trauma centers, in and around each city, over a 48-hour period for disaster scenario sizes of 100, 500, 5000, and 10,000 casualties.
Results
Across all 25 cities, total mean mortality rates ranged from 26.3% in the smallest disaster scenario to 41.9% in the largest. Out-of-hospital mortality rates increased (from 21.3% to 38.5%) while in-hospital mortality rates decreased (from 5.0% to 3.4%) as disaster scenario sizes increased. The mean number of trauma centers involved ranged from 3.0 in the smallest disaster scenario to 63.4 in the largest. Cities that were less geographically isolated with more concentrated trauma centers in their surrounding regions had lower total and out-of-hospital mortality rates. The nine US cities listed as being the most likely targets of terrorist attacks involved, on average, more trauma centers and had lower mortality rates compared with the remaining 16 cities.
Conclusions
The disaster response simulation model discussed here may offer insights to emergency planners and health systems in more realistically planning for mass-casualty events. Longer wait and transport times needed to distribute high numbers of patients to distant trauma centers in fast-onset disasters may create predictable increases in mortality and trauma center resource consumption. The results of the modeled scenarios indicate the need for a systems-based approach to trauma care management during disasters, since the local trauma center network was often too small to provide adequate care for the projected patient surge. Simulation of out-of-hospital resources that might be called upon during disasters, as well as guidance in the appropriate execution of mutual aid agreements and prevention of over-response, could be of value to preparedness planners and emergency response leaders. Study assumptions and limitations are discussed.

Telehealth has great promise to improve and even revolutionize emergency response and recovery. Yet telehealth in general, and direct-to-consumer (DTC) telehealth in particular, are underutilized in disasters. Direct-to-consumer telehealth services allow patients to request virtual visits with health care providers, in real-time, via phone or video conferencing (online video or mobile phone applications). Although DTC services for routine primary care are growing rapidly, there is no published literature on the potential application of DTC telehealth to disaster response and recovery because these services are so new. This report presents several potential uses of DTC telehealth across multiple disaster phases (acute response, subacute response, and recovery) while noting the logistical, legal, and policy challenges that must be addressed to allow for expanded use.

Traditionally, Emergency Medical Services (EMS) educators have divided the pediatric population into age groups to assist in targeting their clinical and didactic curriculum. Currently, the accrediting body for paramedic training programs requires student exposure to pediatric patients based entirely on age without specifying exposure to specific pathologies within each age stratification. Identifying which pathologies are most common within the different pediatric age groups would allow educators to design curriculum targeting the most prevalent pathologies in each age group and incorporating the physiologic and psychological developmental milestones commonly seen at that age.
Hypothesis
It was hypothesized that there are unique clusterings of pathologies, represented by paramedic student primary impressions, that are found in different age groups which can be used to target provider education.
Methods
This is a retrospective review of prospectively collected data documented by paramedic students in the Fisdap (Field Internship Student Data Acquisition Project; Saint Paul, Minnesota USA) database over a one-year period. For the purposes of this study, pediatric patients were defined arbitrarily as those between the ages of 0-16 years. All paramedic student primary impressions recorded in Fisdap for patients aged 0-16 years were abstracted. Primary impression by age was calculated and graphed. The frequency of primary impression was then assessed for significance of trend by age with an alpha ≤.05 considered significant.
Results
The following primary impressions showed clinically and statistically significant variability in prevalence among different pediatric age groups: respiratory distress, medical-other, abdominal pain, seizure, overdose/poisoning, behavioral, and cardiac. In patients less than 13 years old, respiratory and other-medical were the most common two primary impressions and both decreased with age. In patients 5-16 years old, the prevalence of abdominal pain and behavioral/psych increased. Bimodal distributions for overdose were seen with one spike in the toddler and another in the adolescent population. Seizures were most common in the age group associated with febrile seizure. Sepsis was seen most often in the youngest patients and its prevalence decreased with age.
Conclusion
There are statistically significant variations in the frequency of paramedic student primary impressions as a function of age in the pediatric population. Emphasizing paramedic student exposure to the most common pathologies encountered in each age group, in the context of the psychological and physiological milestones of each age, may improve paramedic student pediatric practice.

The preparedness level of Finnish Emergency Medical Services (EMS) for treating chemical emergencies is unknown. The aim of this study was to survey the preparedness level of EMS systems for managing and handling mass-casualty chemical incidents in the prehospital phase in Finland.
Hypothesis
The study hypothesis was that university hospital districts would have better clinical capability to treat patients than would central hospital districts in terms of the number of patients treated in the field within one hour after dispatching as well as patients transported to hospital within one hour or two hours after dispatching.
Methods
This cross-sectional study was conducted as a Webropol (Wuppertal, Germany) survey. All hospital districts (n=20) in continental Finland were asked about their EMS preparedness level in terms of capability of treating and transporting chemically affected patients in the field. Their capability for decontamination of affected patients in the field was also inquired.
Results
University hospital district-based EMS systems had at least 20% better absolute clinical capacity than central hospital-based EMS systems for treating chemically affected patients concerning all treatments inquired about, except the capacity for non-invasive ventilation (NIV)/continuous positive airway pressure (CPAP) treatment in the field. Overall, there was a good level of preparedness for treating chemical accident patients with supplemental oxygen, bronchodilators, and inhaled corticosteroids. Preparedness for providing antidote therapy in cases of cyanide gas exposure was, in general, low. The variation among the hospital districts was remarkable. Only nine of 15 central hospital district EMS had a mobile decontamination unit available, whereas four of five university hospital districts had one.
Conclusion
Emergency Medical Services capacity in Finland for treating chemically affected patients in the field needs to be improved, especially in terms of antidote therapy. Mobile decontamination units should be available in all hospital districts.

Emergency Medical Service (EMS) systems are vital in the identification, assessment, and treatment of trauma, stroke, myocardial infarction, and sepsis patients, improving early recognition, resuscitation, and transport. Emergency Medical Service personnel provide similar care for patients with syncope. The role of EMS in the management of patients with syncope has not been reported.
Hypothesis/Objective
The objective of this study was to describe the management of out-of-hospital syncope by prehospital providers in an urban EMS system.
Methods
This was a retrospective cohort study of consecutively enrolled patients over 18 years of age, over a two-year period, who presented by EMS with syncope, or near-syncope, to a tertiary care emergency department (ED). Demographics included comorbidities, history, and physical exam findings documented by prehospital providers, as well as the interventions provided. Data were collected from standardized patient care records for descriptive analysis.
Results
Of the 723 patients presenting with syncope to the ED, 284 (39.3%) were transported by EMS. Compared to non-EMS patients, those who arrived by ambulance were older (mean age 65 [SD = 18.5] years versus 61 [SD = 19.2] years; P = .019). There were no statistically significant differences in cardiovascular comorbidities (hypertension, coronary artery disease, diabetes mellitus, stroke, or congestive heart failure) between EMS and non-EMS patients. The most common chief complaints were fainting (50.0%) and dizziness (44.7%). The most common intervention provided was cardiac monitoring (55.6%), followed by administration of normal saline infusion (50.5%), oxygen (41.9%), blood glucose check (41.5%), and electrocardiogram (EKG; 40.5%).
Conclusion
Emergency Medical Service personnel transport more than one-third of patients presenting to the ED with syncope. Documentation of key elements of the history (witnesses, prodrome, predisposing factors, and post-event symptoms) and physical examination were not recorded consistently.

Disasters often overwhelm a community’s capacity to respond and recover, creating a gap between the needs of the community and the resources available to provide services. In the wake of multiple disasters affecting nursing homes in the last decade, increased focus has shifted to this vital component of the health care system. However, the long-term care sector has often fallen through the cracks in both planning and response.
Problem
Two recent reports (2006 and 2012) published by the US Department of Health and Human Services (DHHS), Office of Inspector General (OIG), elucidate the need for improvements in nursing homes’ comprehensive emergency preparedness and response. The Center for Medicare and Medicaid Services (CMS) has developed an emergency preparedness checklist as a guidance tool and proposed emergency preparedness regulations. The purpose of this study was to evaluate the progress made in nursing home preparedness by determining the level of completion of the 70 tasks noted on the checklist. The study objectives were to: (1) determine the preparedness levels of nursing homes in North and South Carolina (USA), and (2) compare these findings with the 2012 OIG’s report on nursing home preparedness to identify current gaps.
Methods
A survey developed from the checklist of items was emailed to 418 North Carolina and 193 South Carolina nursing home administrators during 2014. One hundred seventeen were returned/“bounced back” as not received. Follow-up emails and phone calls were made to encourage participation. Sixty-three completed surveys and 32 partial surveys were received. Responses were compared to data obtained in a 2010 study to determine progress.
Results
Progress had been made in many of the overall planning and sheltering-in-place tasks, such as having contact information of local emergency managers as well as specifications for availability of potable water. Yet, gaps still persisted, especially in evacuation standards, interfacing with emergency management officials, establishing back-up evacuation sites and evacuation routes, identification of resident care items, and obtaining copies of state and local emergency planning regulations.
Conclusion
Nursing homes have made progress in preparedness tasks, however, gaps persist. Compliance may prove challenging for some nursing homes, but closer integration with emergency management officials certainly is a step in the right direction. Further research that guides evacuation or shelter-in-place decision making is needed in light of persistent challenges in completing these tasks.

The science underpinning mass-gathering health (MGH) is developing rapidly. However, MGH terminology and concepts are not yet well defined or used consistently. These variations can complicate comparisons across settings. There is, therefore, a need to develop consensus and standardize concepts and data points to support the development of a robust MGH evidence-base for governments, event planners, responders, and researchers. This project explored the views and sought consensus of international MGH experts on previously published concepts around MGH to inform the development of a transnational minimum data set (MDS) with an accompanying data dictionary (DD).
Report
A two-round Delphi process was undertaken involving volunteers from the World Health Organization (WHO) Virtual Interdisciplinary Advisory Group (VIAG) on Mass Gatherings (MGs) and the MG section of the World Association for Disaster and Emergency Medicine (WADEM). The first online survey tested agreement on six key concepts: (1) using the term “MG HEALTH;” (2) purposes of the proposed MDS and DD; (3) event phases; (4) two MG population models; (5) a MGH conceptual diagram; and (6) a data matrix for organizing MGH data elements. Consensus was defined as ≥80% agreement. Round 2 presented five refined MGH principles based on Round 1 input that was analyzed using descriptive statistics and content analysis. Thirty-eight participants started Round 1 with 36 completing the survey and 24 (65% of 36) completing Round 2. Agreement was reached on: the term “MGH” (n=35/38; 92%); the stated purposes for the MDS (n=38/38; 100%); the two MG population models (n=31/36; 86% and n=30/36; 83%, respectively); and the event phases (n=34/36; 94%). Consensus was not achieved on the overall conceptual MGH diagram (n=25/37; 67%) and the proposed matrix to organize data elements (n=28/37; 77%). In Round 2, agreement was reached on all the proposed principles and revisions, except on the MGH diagram (n=18/24; 75%).
Discussion/Conclusions
Event health stakeholders require sound data upon which to build a robust MGH evidence-base. The move towards standardization of data points and/or reporting items of interest will strengthen the development of such an evidence-base from which governments, researchers, clinicians, and event planners could benefit. There is substantial agreement on some broad concepts underlying MGH amongst an international group of MG experts. Refinement is needed regarding an overall conceptual diagram and proposed matrix for organizing data elements.

Disaster triage is the allocation of limited medical resources in order to optimize patient outcome. There are several studies showing the poor use of triage tagging, but there are few studies that have investigated the reasons behind this. The aim of this study was to explore ambulance personnel attitude towards, and experiences of, practicing triage tagging during day-to-day management of trauma patients, as well as in major incidents (MIs).
Methods
A mixed method design was used. The first part of the study was in the form of a web-survey of attitudes answered by ambulance personnel. The question explored was: Is it likely that systems that are not used in everyday practice will be used during MIs? Two identical web-based surveys were conducted, before and after implementing a new strategy for triage tagging. This strategy consisted of a time-limited triage routine where ambulance services assigned triage category and applied triage tags in day-to-day trauma incidents in order to improve field triage. The second part comprised three focus group interviews (FGIs) in order to provide a deeper insight into the attitudes towards, and experience of, the use of triage tags. Data were analyzed using qualitative content analysis.
Results
The overall finding was the need for daily routine when failure in practice. Analysis of the web-survey revealed three changes: ambulance personnel were more prone to use tags in minor accidents, the sort scoring system was considered to be more valuable, but it also was more time consuming after the intervention. In the analysis of FGIs, four categories emerged that describe the construction of the overall category: perceived usability, daily routine, documentation, and need for organizational strategies.
Conclusion
Triage is part of the foundation of ambulance skills, but even so, ambulance personnel seldom use this in routine practice. They fully understand the benefit of accurate triage decisions, and also that the use of a triage algorithm and color coded tags is intended to make it easier and more secure to perform triage. However, despite the knowledge and understanding of these benefits, sparse incidents and infrequent exercises lead to ambulance personnel’s uncertainty concerning the use of triage tagging during a MI and will therefore, most likely, avoid using them.

Obtaining intravenous (IV) access in patients in hemorrhagic shock is often difficult and prolonged. Failed IV attempts delay life-saving treatment. Intraosseous (IO) access may often be obtained faster than IV access. Albumin (5%) is an option for prehospital volume expansion because of the absence of interference with coagulation and platelet function.
Hypothesis/Problem
There are limited data comparing the performance of IO and IV administered 5% albumin. The aims of this study were to compare the effects of tibial IO (TIO) and IV administration of 500 mL of 5% albumin on infusion time and hemodynamic measurements of heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), and stroke volume (SV) in a swine model of hemorrhagic shock.
Methods
Sixteen male swine were divided into two groups: TIO and IV. All subjects were anesthetized and a Class III hemorrhage was achieved by exsanguination of 31% of estimated blood volume (EBV) from a femoral artery catheter. Following exsanguination, 500 mL of 5% albumin was administered under pressurized infusion (300 mmHg) by the TIO or IV route and infusion time was recorded. Hemodynamic measurements of HR, MAP, CO, and SV were collected before and after exsanguination and every 20 seconds for 180 seconds during 5% albumin infusion.
Results
An independent t-test determined that IV 5% albumin infusion was significantly faster compared to IO (P=.01). Mean infusion time for TIO was seven minutes 35 seconds (SD=two minutes 44 seconds) compared to four minutes 32 seconds (SD=one minute 08 seconds) in the IV group. Multivariate Analysis of Variance was performed on hemodynamic data collected during the 5% albumin infusion. Analyses indicated there were no significant differences between the TIO and IV groups relative to MAP, CO, HR, or SV (P>.05).
Conclusion
While significantly longer to infuse 5% albumin by the TIO route, the longer TIO infusion time may be negated as IO devices can be placed more quickly compared to repeated IV attempts. The lack of significant difference between the TIO and IV routes relative to hemodynamic measures indicate the TIO route is a viable route for the infusion of 5% albumin in a swine model of Class III hemorrhage.

Violence against women (VAW) is one of the most widespread violations of human rights and a major barrier to achieving gender equality. Violence against women is increased in disaster-stricken communities. Violence experiences, cases, and lessons-learned concerning Iran’s disasters have not been investigated, documented, or shared so far. To fill this knowledge gap, this qualitative study aimed to explore types of VAW and girls after the recent quakes and floods in Iran.
Problem
The objective for this study was exploring the manifestations of VAW after the natural disasters in Iran.
Methods
A qualitative approach was used for this study. Data were collected by in-depth, unstructured interviews and field observations in three affected regions of Iran, including East Azerbaijan, Bushehr, and Mazandaran. A total of 15 participants, eight damaged women as well as seven key informants, were interviewed. A content analysis using Graneheim approach was performed for analyzing transcribed interviews.
Results
Two main themes were extracted from data, including domestic violence and violence within community. The first theme included three categories: physical, psychological, and sexual violence. Psychological violence and sexual harassment were two categories of violence within the community concept.
Conclusion
Different types of violence emerged from the present research that can be anticipated and integrated into future disaster medicine plans, public health reforms, and national rules of Iran. Improving women’s knowledge on their rights to have a life without violence, and participation of both women and men in violence reduction projects, can be considered in all disaster management phases.

Hospitals are meant to be places for respite and healing; however, technological advances and reliance on monitoring alarms has led to the environment becoming increasingly noisy. The coronary care unit (CCU), like the emergency department, provides care to ill patients while being vulnerable to noise pollution. The World Health Organization (WHO; Geneva, Switzerland) recommends that for optimum rest and healing, sound levels should average approximately 30 decibels (dB) with maximum readings less than 40 dB.
Problem
The purpose of this study was to measure and analyze sound levels in three different locations in the CCU, and to review alarm reports in relation to sound levels.
Methods
Over a one-month period, sound recorders (Extech SDL600; Extech Instruments; Nashua, New Hampshire USA) were placed in three separate locations in the CCU at the West Roxbury Veterans’ Administration (VA) Hospital (Roxbury, Massachusetts USA). Sound samples were recorded once per second, stored in Comma Separated Values format for Excel (Microsoft Corporation; Redmond, Washington USA), and then exported to Microsoft Excel. Averages were determined, plotted per hour, and alarm histories were reviewed to determine alarm noise effect on total noise for each location, as well as common alarm occurrences.
Results
Patient Room 1 consistently had the lowest average recordings, though all averages were >40 dB, despite decreases between 10:00 pm and 7:00 am. During daytime hours, recordings maintained levels >50 dB. Overnight noise remained above recommended levels 55.25% of the period in Patient Room 1 and 99.61% of the same time period in Patient Room 7. The nurses’ station remained the loudest location of all three. Alarms per hour ranged from 20-26 during the day. Alarms per day averaged: Patient Room 1-57.17, Patient Room 7-122.03, and the nurses’ station - 562.26. Oxygen saturation alarms accounted for 33.59% of activity, and heart-related (including ST segment and pacemaker) accounted for 49.24% of alarms.
Conclusion
The CCU cares for ill patients requiring constant monitoring. Despite advances in technology, measured noise levels for the hospital studied exceeded WHO standards of 40 dB and peaks of 45 dB, even during night hours when patients require rest. Further work is required to reduce noise levels and examine effects on patient satisfaction, clinical outcomes, and length of stay.

This is a report of a fortunate story of an unusual AK-47 bullet trajectory which took place during the Paris (France) attack of November 13th, 2015. A young man, trying to protect his girlfriend, interfered between her and a shooter. He had been wounded in the posterior compartment of the thigh. The bullet penetrated him and, instead of exiting, rebound against his Smartphone, which was in the front pocket of his pants. Thanks to that, the missile bullet did not injure his girlfriend but ended its trajectory in the fat tissue of his thigh.

The aim of this study was to describe an educational method teaching Disaster Medicine to American Emergency Medicine (EM) physicians and to evaluate knowledge attainment using this method.
Methods
This was an observational study using a pre-test and a post-test. A full-scale disaster exercise (FSE) was conducted at a large academic center with two hospitals in Brooklyn, New York (USA). Eighty-two EM residents (physicians in training, post medical school) participated in the study. Inclusion criteria for study participation was all EM residents training at the State University of New York (SUNY) Downstate at the time of the study. There were no exclusion criteria. The exercise was a disaster drill designed as “Olympic Games.” Participants in the exercise took a pre-test and a post-test. The primary outcome of the study was the mean difference between pre-test and post-test scores of the study participants using independent sample t-tests. Secondary outcomes of the study were percent of critical actions met by the residents and the hospitals as measured by direct observation of trained study personnel during the exercise.
Results
Mean resident post-test scores were higher than pre-test scores to a degree that was statistically significant (62% versus 53%; P =.002). The residents’ performances ranged from 48% to 63% of objectives met. The hospitals’ performances met 50% to 100% of their objectives.
Conclusion
The use of an Olympic Games format was an effective model for disaster education for physicians. The model allowed for evaluation of performance and protocols of participants and hospital systems, respectively, and may be used objectively to evaluate for areas of improvement. The Disaster Olympics drill was found to improve emergency preparedness knowledge in the population studied and may constitute a novel and efficacious methodology in disaster training.

On October 29, 2012, Hurricane Sandy touched down in New York City (NYC; New York USA) causing massive destruction, paralyzing the city, and destroying lives. Research has shown that considerable damage and loss of life can be averted in at-risk areas from advanced preparation in communication procedures, evacuation planning, and resource allocation. However, research is limited in describing how natural disasters of this magnitude affect emergency departments (EDs).
Hypothesis/Problem
The aim of this study was to identify and describe trends in patient volume and demographics, and types of conditions treated, as a result of Hurricane Sandy at Staten Island University Hospital North (SIUH-N; Staten Island, New York USA) site ED.
Methods
A retrospective chart review of patients presenting to SIUH-N in the days surrounding the storm, October 26, 2012 through November 2, 2012, was completed. Data were compared to the same week of the year prior, October 28, 2011 through November 4, 2011. Daily census, patient age, gender, admission rates, mode of arrival, and diagnoses in the days surrounding the storm were observed.
Results
A significant decline in patient volume was found in all age ranges on the day of landfall (Day 0) with a census of 114; -55% compared to 2011. The daily volume exhibited a precipitous drop on the days preceding the storm followed by a return to usual volumes shortly after.
A notably larger percentage of patients were seen for medication refills in 2012; 5.8% versus 0.4% (P<.05). Lacerations and cold exposure also were increased substantially in 2012 at 7.6% versus 2.8% (P<.05) and 3.8% versus 0.0% (P<.05) of patient visits, respectively.
A large decline in admissions was observed in the days prior to the storm, with a nadir on Day +1 at five percent (-22%). Review of admitted patients revealed atypical admissions for home care service such as need for supplemental oxygen or ventilator.
In addition, a drop in Emergency Medical Services (EMS) utilization was seen on Days 0 and +1. The SIUH-N typically sees 18% of patients arriving via EMS. On Day +1, only two percent of patients arrived by ambulance.
Conclusion
The daily ED census saw a significant decline in the days preceding the storm. In addition, the type of conditions treated varied from baseline, and a considerable drop in hospital admissions was seen. Data such as these presented here can help make predictions for future scenarios.

Karachi, Pakistan was affected by a heat wave in June 2015 during the Muslim holy month of Ramadan. Many media reports attributed the excess deaths in part to the practice of daylight fasting during Ramadan. As much of the published research reports on heat-related mortality in Europe and the United States, an exploration of the effects of extreme heat on residents of a South Asian mega-city address a gap in current disaster research.
Hypothesis/Problem
This report investigated potential risk factors for excess mortality associated with the June 2015 heat wave in Karachi, Pakistan.
Methods
Data were obtained through manual review of death certificates at public hospitals and private clinics in Karachi, Pakistan, conducted from July 1 through July 31, 2015 by a trained physician. Demographic data for any deaths with a primary cause of death of heat-related illness were recorded in Microsoft Excel (Microsoft Corp.; Redmond, Washington USA). EpiSheet (2012; Rothman. Modern Epidemiology. Lippincott Williams & Wilkins; Philadelphia, Pennsylvania USA) was used to calculate risk differences (RD), rate ratios (RR), and 95% confidence intervals (95% CI).
Results
Overall, residents of Karachi were approximately 17 times as likely to die of a heat-related cause of death during June 2015 (RR=17.68; 95% CI, 13.87-22.53) when compared with the reference period of June 2014. Residents with a monthly income lower than 20,000 Pakistani Rupees (US $196; RD=0.03; 95% CI, 0.01-0.05) and those with less than a fifth grade education (RD=0.03; 95% CI, 0.00-0.05) were at significantly higher risk of death during the 2015 heat wave compared to the reference period.
Conclusion
Fasting during Ramadan was not a significant risk factor for mortality from heat-related causes during the Karachi heat wave of June 2015. A large number of excess deaths were reported across all demographic groups, which due to the burden of record keeping in an under-resourced health system during a public health emergency, are almost certainly an underestimate.

The Medical Reserve Corps (MRC) is a national network of community-based volunteer groups created in 2002 by the Office of the United States Surgeon General (Rockville, Maryland USA) to augment the nation’s ability to respond to medical and public health emergencies. However, there is little evidence-based literature available to guide hospitals on the optimal use of medical volunteers and hesitancy on the part of hospitals to use them.
Hypothesis/Problem
This study sought to determine how MRC volunteers can be used in hospital-based disasters through their participation in a full-scale exercise.
Methods
A full-scale exercise was designed as a “Disaster Olympics,” in which the Emergency Medicine residents were divided into teams tasked with completing one of the following five challenges: victim decontamination, mass casualty/decontamination tent assembly, patient triage and registration during a disaster, point of distribution (POD) site set-up and operation, and infection control management. A surge of patients potentially exposed to avian influenza was the scenario created for the latter three challenges. Some MRC volunteers were assigned clinical roles. These roles included serving as members of the suit support team for victim decontamination, distributing medications at the POD, and managing infection control. Other MRC volunteers functioned as “victim evaluators,” who portrayed the potential avian influenza victims while simultaneously evaluating various aspects of the disaster response. The MRC volunteers provided feedback on their experience and evaluators provided feedback on the performance of the MRC volunteers using evaluation tools.
Results
Twenty-eight (90%) MRC volunteers reported that they worked well with the residents and hospital staff, felt the exercise was useful, and were assigned clearly defined roles. However, only 21 (67%) reported that their qualifications were assessed prior to role assignment. For those MRC members who functioned as “victim evaluators,” nine identified errors in aspects of the care they received and the disaster response. Of those who evaluated the MRC, nine (90%) felt that the MRC worked well with the residents and hospital staff. Ten (100%) of these evaluators recommended that MRC volunteers participate in future disaster exercises.
Conclusion
Through use of a full-scale exercise, this study was able to identify roles for MRC volunteers in a hospital-based disaster. This study also found MRC volunteers to be uniquely qualified to serve as “victim evaluators” in a hospital-based disaster exercise.

A disaster is a failure of resilience to an event. Mitigating the risks that a hazard will progress into a destructive event, or increasing the resilience of a society-at-risk, requires careful analysis, planning, and execution. The Disaster Logic Model (DLM) is used to define the value (effects, costs, and outcome(s)), impacts, and benefits of interventions directed at risk reduction. A Risk-Reduction Framework, based on the DLM, details the processes involved in hazard mitigation and/or capacity-building interventions to augment the resilience of a community or to decrease the risk that a secondary event will develop. This Framework provides the structure to systematically undertake and evaluate risk-reduction interventions. It applies to all interventions aimed at hazard mitigation and/or increasing the absorbing, buffering, or response capacities of a community-at-risk for a primary or secondary event that could result in a disaster. The Framework utilizes the structure provided by the DLM and consists of 14 steps: (1) hazards and risks identification; (2) historical perspectives and predictions; (3) selection of hazard(s) to address; (4) selection of appropriate indicators; (5) identification of current resilience standards and benchmarks; (6) assessment of the current resilience status; (7) identification of resilience needs; (8) strategic planning; (9) selection of an appropriate intervention; (10) operational planning; (11) implementation; (12) assessments of outputs; (13) synthesis; and (14) feedback. Each of these steps is a transformation process that is described in detail. Emphasis is placed on the role of Coordination and Control during planning, implementation of risk-reduction/capacity building interventions, and evaluation.

There is a lack of knowledge about the early phase of severe infection. This report describes the early chain of care in bacteraemia as follows: (a) compare patients who were and were not transported by the Emergency Medical Services (EMS); (b) describe various aspects of the EMS chain; and (c) describe factors of importance for the delay to the start of intravenous antibiotics. It was hypothesized that, for patients with suspected sepsis judged by the EMS clinician, the delay until the onset of antibiotic treatment would be shorter.
Basic Procedures
All patients in the Municipality of Gothenburg (Sweden) with a positive blood culture, when assessed at the Laboratory of Bacteriology in the Municipality of Gothenburg, from February 1 through April 30, 2012 took part in the survey.
Main Findings/Results
In all, 696 patients fulfilled the inclusion criteria. Their mean age was 76 years and 52% were men. Of all patients, 308 (44%) had been in contact with the EMS and/or the emergency department (ED). Of these 308 patients, 232 (75%) were transported by the EMS and 188 (61%) had “true pathogens” in blood cultures. Patients who were transported by the EMS were older, included more men, and suffered from more severe symptoms and signs.
The EMS nurse suspected sepsis in only six percent of the cases. These patients had a delay from arrival at hospital until the start of antibiotics of one hour and 19 minutes versus three hours and 21 minutes among the remaining patients (P =.0006). The corresponding figures for cases with “true pathogens” were one hour and 19 minutes versus three hours and 15 minutes (P =.009).
Conclusion
Among patients with bacteraemia, 75% used the EMS, and these patients were older, included more men, and suffered from more severe symptoms and signs. The EMS nurse suspected sepsis in six percent of cases. Regardless of whether or not patients with true pathogens were isolated, a suspicion of sepsis by the EMS clinician at the scene was associated with a shorter delay to the start of antibiotic treatment.
