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.

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.

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.

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).

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.

Limited food supply paired with reduced access to food during emergency disasters can lead to malnutrition. To date, research evaluating the adequacy of household emergency food supplies relies on self-reported data from surveys and has not been measured objectively in households in the United States. The main objective of this study was to describe household calorie availability and nutrient density in a normal situation and to project changes that could occur when emergencies (eg, natural disasters) restrict replenishment of food supplies and disrupt water and/or energy needed for food preparation and storage.

The calorie availability of the food supply within households in New Jersey (USA) is anticipated to be well above the recommended 3-day period. However, it is anticipated that the nutritional density of the food supply within these households will be negative. Additionally, the disaster-related factors that diminish the ability to consume stored food (eg, lack of water, power for cooking, and/or proper storage) will further reduce the caloric and nutritional adequacy of the household food supply.

The household food supplies of 100 food secure families in New Jersey were inventoried at a non-emergency point in time. The number of days that the inventoried food supply would provide all household members 100% of the daily value (DV) for calories and other nutrients was determined. Additionally, the effects of water and power shortages on nutritional availability of household food supply were estimated.

The households had an average of 33.16 days (SD=21.97; range=8.14-125.17 days) of calories at 100% DV for all household members. Lack of water, energy for cooking, or both would render a decrease in the total household calories by 28%, 35%, or 38%, respectively. Loss of power for greater than five days would reduce availability of household calories by 27%. A positive nutrient density was observed with and without the food-related resources of water and power.

The mean food supply within the sampled households exceeds the current emergency preparedness recommendations, even when considering specific nutrients and emergency-related factors that affect ability to consume the food supply. Cross-sectional observation of the household food supply of food secure families in New Jersey reveals adequate dietary-based emergency preparedness and low vulnerability to emergency-induced food insecurity.

The most effective dose of prehospital furosemide in acute decompensated heart failure (ADHF) has not yet been identified and concerns of worsening renal function have limited its use.

To assess if administering high-dose furosemide is associated with worsening renal function.

The authors conducted a 2-center chart review for patients who presented via a single Emergency Medical Service (EMS) from June 5, 2009 through May 17, 2013. Inclusion criteria were shortness of breath, primarily coded as ADHF, and the administration of furosemide prior to emergency department (ED) arrival. A total of 331 charts were identified. The primary endpoint was an increase in creatinine (Cr) of more than 0.3 mg/dL from admission to any time during hospital stay. Exploratory endpoints included survival, length-of-stay (LOS), disposition, urine output in the ED, change in BUN/Cr from admission to discharge, and change in Cr from admission to 72 hours and discharge.

When treated as a binary variable, there was no association observed between an increase in Cr of more than 0.3 mg/dL and prehospital furosemide dose. Baseline characteristics found to be associated with dose were included in the logistic regression model. Lowering the dose of prehospital furosemide was associated with higher odds of attaining a 0.3 mg/dL increase in Cr (adjusted OR = 1.49 for a 20 mg decrease; P = .019). There was no association found with any of the exploratory endpoints.

Patients who received higher doses of furosemide prehospitally were less likely to have an increase of greater than 0.3 mg/dL in Cr during the hospital course.

The challenges presented by traumatic injuries in low-resource communities are especially relevant in South Sudan. This study was conducted to assess whether a 3-day wilderness first aid (WFA) training course taught in South Sudan improved first aid knowledge. Stonehearth Open Learning Opportunities (SOLO) Schools designed the course to teach people with limited medical knowledge to use materials from their environment to provide life-saving care in the event of an emergency.

A pre-test/post-test study design was used to assess first aid knowledge of 46 community members in Kit, South Sudan, according to a protocol approved by the University of New England Institutional Review Board. The course and assessments were administered in English and translated in real-time to Acholi and Arabic, the two primary languages spoken in the Kit region. Descriptive statistics, t-test, ANOVA, and correlation analyses were conducted.

Results included a statistically significant improvement in first aid knowledge after the 3-day training course: t(38)=3.94; P<.001. Although men started with more health care knowledge: (t(37)=2.79; P=.008), men and women demonstrated equal levels of knowledge upon course completion: t(37)=1.56; P=.88.

This research, which may be the first of its kind in South Sudan, provides evidence that a WFA training course in South Sudan is efficacious. These findings suggest that similar training opportunities could be used in other parts of the world to improve basic medical knowledge in communities with limited access to medical resources and varying levels of education and professional experiences.

Needle thoracostomy is the prehospital treatment for tension pneumothorax. Sufficient catheter length is necessary for procedural success. The authors of this study determined minimum catheter length needed for procedural success on a percentile basis.

A meta-analysis of existing studies was conducted. A Medline search was performed using the search terms: needle decompression, needle thoracentesis, chest decompression, pneumothorax decompression, needle thoracostomy, and tension pneumothorax. Studies were included if they published a sample size, mean chest wall thickness, and a standard deviation or confidence interval. A PubMed search was performed in a similar fashion. Sample size, mean chest wall thickness, and standard deviation were found or calculated for each study. Data were combined to create a pooled dataset. Normal distribution of data was assumed. Procedural success was defined as catheter length being equal to or greater than the chest wall thickness.

The Medline and PubMed searches yielded 773 unique studies; all study abstracts were reviewed for possible inclusion. Eighteen papers were identified for full manuscript review. Thirteen studies met all inclusion criteria and were included in the analysis. Pooled sample statistics were: n=2,558; mean=4.19 cm; and SD=1.37 cm. Minimum catheter length needed for success at the 95th percentile for chest wall size was found to be 6.44 cm.

A catheter of at least 6.44 cm in length would be required to ensure that 95% of the patients in this pooled sample would have penetration of the pleural space at the site of needle decompression, and therefore, a successful procedure. These findings represent Level III evidence.

The Glasgow Coma Scale (GCS) is widely applied in the emergency setting; it is used to guide trauma triage and for the application of essential interventions such as endotracheal intubation. However, inter-rater reliability of GCS scoring has been shown to be low for inexperienced users, especially for the motor component. Concerns regarding the accuracy and validity of GCS scoring between various types of emergency care providers have been expressed.

The objective of this study was to determine the degree of accuracy of GCS scoring between various emergency care providers within a modern Emergency Medical Services (EMS) system.

This was a prospective observational study of the accuracy of GCS scoring using a convenience sample of various types of emergency medical providers using standardized video vignettes. Ten video vignettes using adults were prepared and scored by two board-certified neurologists. Inter-rater reliability was excellent (Cohen's κ = 1). Subjects viewed the video and then scored each scenario. The scoring of subjects was compared to expert scoring of the two board-certified neurologists.

A total of 217 emergency providers watched 10 video vignettes and provided 2,084 observations of GCS scoring. Overall total GCS scoring accuracy was 33.1% (95% CI, 30.2-36.0). The highest accuracy was observed on the verbal component of the GCS (69.2%; 95% CI, 67.8-70.4). The eye-opening component was the second most accurate (61.2%; 95% CI, 59.5-62.9). The least accurate component was the motor component (59.8%; 95% CI, 58.1-61.5). A small number of subjects (9.2%) assigned GCS scores that do not exist in the GCS scoring system.

Glasgow Coma Scale scoring should not be considered accurate. A more simplified scoring system should be developed and validated.

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.

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.

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.

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.

Prompt prehospital care is essential for improving outcomes of road crash victims; however, this service is sub-optimal in developing countries because Emergency Medical Services (EMS) are not readily available. Training of lay responders in first aid has been suggested as a means of filling this gap in settings with inadequate EMS. This study was conducted to determine the effect of first aid training on the first aid knowledge and skills of commercial drivers.

A before-and-after study was conducted among 128 commercial drivers (62 intervention and 66 controls) selected by multi-stage sampling. Drivers’ first aid knowledge and skills were assessed at baseline, immediate, and three months post-intervention. The intervention involved a 2-day training session in first aid. Repeated measures ANOVA was used to test for differences in respondents’ pre- and post-intervention scores over the three assessment points.

Mean first aid knowledge scores for intervention drivers were 48.9% (SD=12.0), 57.8% (SD=11.2), and 59.2% (SD=9.0) at baseline, immediate, and three months post-intervention. Corresponding scores for the controls were 48.3% (SD=12.8), 39.2% (SD=15.3), and 46.8% (SD=15.3). Mean first aid skill scores for intervention drivers were 17.5% (SD=3.8), 80.7% (SD=8.3), and 72.3% (SD=16.8). Scores for control drivers were 16.5% (SD=4.5), 16.3% (SD=4.7), and 20.4% (SD=9.1), respectively. Repeated measures ANOVA showed significant differences in first aid knowledge and skills scores over the three phases. Independent t-test revealed significant differences in scores between the intervention and control groups post-intervention.

The training led to significant improvement in first aid knowledge and skills of intervention drivers. This confirms that lay responders can be trained in provision of first aid. The slight drop in skills scores, which occurred three months post-intervention, highlights the need for periodic refresher trainings to be conducted for the drivers in order to maintain the knowledge and skills acquired.

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.

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.

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.

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.

Aortic dissection is difficult to detect in the early phase due to a variety of symptoms. This report describes the prehospital setting of aortic dissection in terms of symptoms, treatment, and suspicion by the Emergency Medical Service (EMS) staff.

All patients in the Municipality of Gothenburg, Sweden, who, in 2010 and 2011, had a hospital discharge diagnosis of aortic dissection (international classification of disease (ICD) I 71,0) were included. The exclusion criteria were: age < 18 years of age and having a planned operation. This was a retrospective, descriptive study based on patient records. In the statistical analyses, Fisher's exact test and the Mann-Whitney U test were used for analyses of dichotomous and continuous/ordered variables.

Of 92 patients, 78% were transported to the hospital by the EMS. The most common symptom was pain (94%). Pain was intensive or very intensive in 89% of patients, with no significant difference in relation to the use of the EMS. Only 47% of those using the EMS were given pain relief with narcotic analgesics. Only 12% were free from pain on admission to the hospital. A suspicion of aortic dissection was reported by the EMS staff in only 17% of cases. The most common preliminary diagnosis at the dispatch center (31%) and by EMS clinicians (52%) was chest pain or angina pectoris. In all, 79% of patients were discharged alive from the hospital (75% of those that used the EMS and 95% of those that did not).

Among patients who were hospitalized due to aortic dissection in Gothenburg, 78% used the EMS. Despite severe pain in the majority of patients, fewer than half received narcotic analgesics, and only 12% were free from pain on admission to the hospital. In fewer than one-in-five patients was a suspicion of aortic dissection reported by the EMS staff.

An adequate level of personal protective equipment (PPE) is necessary when treating patients with highly infectious diseases or those contaminated with hazardous substances.

Following National Institute for Health Research’s Research Centre (London, United Kingdom) approval, the authors of this study conducted a survey of specialist registrars’ knowledge of the respiratory and skin protection requirements needed during a resuscitation scenario with Advanced Life Support. Participant responses were compared to UK national recommendations and to a previous survey in 2009.

A total of 98 specialist registrars (in Anesthesiology, n=51; in Emergency Medicine (EM), n=21; and in Intensive Care Medicine (ICM) n=26) completed hand-delivered surveys. The best knowledge of PPE requirements (76%) was found for severe acute respiratory syndrome (SARS), with less knowledge about PPE requirements for anthrax, plague, Ebola virus disease (EVD), and smallpox (60%). The results show limited knowledge of PPE requirements (20%-30%) for various chemical warfare agents. Personal protective equipment knowledge regarding treatment of sarin-contaminated casualties was over-rated by 80%, and for patients with EVD, it was over-rated by up to 67% of participants.

The results of the tested cohort indicate that current knowledge regarding PPE for chemical warfare agents remains very limited.

Despite landmine-risk education programs and extensive demining activities on the Western border of Iran, landmines and unexploded ordnance (UXOs) still cause civilian and child casualties three decades after the Iraq-Iran war (1980-1988). The objective of this study was to understand the epidemiological patterns and risk factors of injury in child casualties of landmines and UXOs in Western and Southwestern Iran.

Children who were 18 years old or younger at the time of study and who sustained injuries from landmines and UXOs were identified through a search at the Iranian National Veterans Registry. These children participated in a 5-day gathering. The information on socioeconomic status, health-related issues, quality of life, health care utilization, and clinical profiles concerning the landmine and UXO injuries were collected. The method of data collection consisted of three component surveys: health interview, social survey, and medical examinations. Social surveys and health interviews were conducted in a face-to-face method by utilizing a questionnaire consisting of 39 questions addressing household and individual components, including information on time and type of injuries, physical activity, mental health, and quality of life. A comprehensive team of physicians in different subspecialties evaluated and examined children to assess the current medical and psychiatric conditions and physical activity, and recommended and arranged further medical, rehabilitation, or surgical planning.

Seventy-eight child casualties were identified and participated in the study. The mean age of the participants at the time of study was 16.11 years old (SD=2 years). The mean age of victims at the time of injury was 8.2 years (SD=3.12 years; ranged from 2 to 15 years old). Sixty-seven (85.9%) of the children were male. Provinces of Kurdistan and Kermanshah had the highest number of casualties, with a total number of 54 children (68.3%). Eighty percent of the injuries were caused by landmines, and UXO explosions were reported in 20% of the cases. Overall, 24 children (30%) had received some landmine-risk education before or after the events. Sixty percent of the explosions had happened in the morning between 9:00 am and 12:00 pm. Playing and grazing livestock were the most prevalent activities/reasons at the time of injury, which were reported in 77% of the subjects. Sixty-three percent of incidents had multiple casualties and in only 13 explosions were the children the only victims of the explosion. The most prevalent injuries were amputations in 41 subjects (52.56%), followed by hearing loss in 23 subjects (29.5%). Amputations were more common in upper extremities (62%) than in lower extremities (38%).

Landmines and UXOs comprise a significant safety hazard to the children living in the Western border of Iran decades after the Iraq-Iran War. The large number of injuries and lack of risk training among victims suggest that landmine cleanings and landmine-risk education should be age-specifically targeted and expanded substantially.

Prehospital Emergency Medical Services (EMS) providers are expected to treat all patients the same, regardless of race, gender identity, sexual orientation, or religion. Some EMS personnel who are poorly trained in working with lesbian, gay, bisexual, and transgender (LGBT) patients are at risk for managing such patients incompletely and possibly incorrectly. During emergency situations, such mistreatment has meant the difference between life and death.

An anonymous survey was electronically distributed to EMS educational program directors in Maryland (USA). The survey asked participants if their program included training cultural sensitivity, and if so, by what modalities. Specific questions then focused on information about LGBT education, as well as related topics, that they, as program directors, would want included in an online training module.

A total of 20 programs met inclusion criteria for the study, and 16 (80%) of these programs completed the survey. All but one program (15, 94%) included cultural sensitivity training. One-third (6, 38%) of the programs reported already teaching LGBT-related issues specifically. Three-quarters of the programs that responded (12, 75%) were willing to include LGBT-related material into their curriculum. All programs (16, 100%) identified specific aspects of LGBT-related emergency health issues they would be interested in having included in an educational module.

Most EMS educational program directors in Maryland are receptive to including LGBT-specific education into their curricula. The information gathered in this survey may help guide the development of a short, self-contained, open-access module for EMS educational programs. Further research, on a broader scale and with greater geographic sampling, is needed to assess the practices of EMS educators on a national level.

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.

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.

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.

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.

Optimal emergent management of traumatic hemorrhagic shock patients requires a better understanding of treatment provided in the prehospital/Emergency Medical Services (EMS) and emergency department (ED) settings.

Described in this research are the initial clinical status, airway management, fluid and blood infusions, and time course of severely-injured hemorrhagic shock patients in the EMS and ED settings from the diaspirin cross-linked hemoglobin (DCLHb) clinical trial.

Data were analyzed from 17 US trauma centers gathered during a randomized, controlled, single-blinded efficacy trial of a hemoglobin solution (DCLHb) as add-on therapy versus standard therapy.

Among the 98 randomized patients, the mean EMS Glasgow Coma Scale (GCS) was 10.6 (SD = 5.0), the mean EMS revised trauma score (RTS) was 6.3 (SD = 1.9), and the mean injury severity score (ISS) was 31 (SD = 17). Upon arrival to the ED, the GCS was 20% lower (7.8 (SD = 5.3) vs 9.7 (SD = 6.3)) and the RTS was 12% lower (5.3 (SD = 2.0) vs 6.0 (SD = 2.1)) than EMS values in blunt trauma patients (P < .001). By ED disposition, 80% of patients (78/98) were intubated. Rapid sequence intubation (RSI) was utilized in 77% (60/78), most often utilizing succinylcholine (65%) and midazolam (50%). The mean crystalloid volume infused was 4.2 L (SD = 3.4 L), 80% of which was infused within the ED. Emergency department blood transfusion occurred in 62% of patients, with an average transfused volume of 1.2 L (SD = 2.0 L). Blunt trauma patients received 2.1 times more total fluids (7.4 L vs 3.5 L, < .001) and 2.4 times more blood (2.4 L vs 1.0 L, P < .001). The mean time of patients taken from injury site to operating room (OR) was 113 minutes (SD = 87 minutes). Twenty-one (30%) of the 70 patients taken to the OR from the ED were sent within 60 minutes of the estimated injury time. Penetrating trauma patients were taken to the OR 52% sooner than blunt trauma patients (72 minutes vs 149 minutes, P < .001).

Both GCS and RTS decreased prior to ED arrival in blunt trauma patients. Intubation was performed using RSI, and crystalloid infusion of three times the estimated blood loss volume (L) and blood transfusion of the estimated blood loss volume (L) were provided in the EMS and ED settings. Surgical intervention for these trauma patients most often occurred more than one hour from the time of injury. Penetrating trauma patients received surgical intervention more rapidly than those with a blunt trauma mechanism.

The aim of this study was to describe the most recent trends and epidemiologic patterns of fatal injuries resulting from explosions in Iraq, one of the countries most affected by violence from explosive devices.

Iraqi Ministry of Health (MoH) routine prospective injury surveillance collects information on all fatal injuries recorded by coroners from physical examinations, police reports, and family members in eight governorates of Iraq: Baghdad, Al-Anbar, Basrah, Erbil, Kerbala, Maysan, Ninevah, and Al-Sulaimaniya. This study analyzed explosive-related fatal injuries that occurred from January 1, 2010 through December 31, 2013.

Analysis included 2,803 fatal injuries. The number of fatal injuries declined from 2010 through 2012, followed by an increase in 2013. One-thousand one-hundred and one explosion-related fatalities were documented in 2013, more than twice as many as in 2012 or in 2011. Most fatalities were among men aged 20-39 years. Of all causalities, 194 (6.9%) were among females and 302 (10.8%) were among children aged less than 18 years. The majority of fatalities were caused by improvised explosive devices (IEDs): car bombs (15.3%), suicide bombs (4.0%), and other IEDs (29.6%). The highest number of fatalities occurred in streets and roads. Of all deaths, 95.6% occurred in three governorates: Baghdad, Ninevah, and Al-Anbar.

Explosives continue to result in a high number of fatal injuries in Iraq. Following a period of declining violence from explosives, in 2013, fatalities increased. Most explosion-related injuries resulted from IEDs; males aged 20-39 years were at greatest risk.

Management of contaminated patients in the decontamination corridor requires the use of hazardous material (HazMat) personal protective equipment (PPE). Previous studies have demonstrated that HazMat PPE may increase the difficulty of airway management. This study compared the efficiency of video laryngoscopy (VL) with traditional direct laryngoscopy (DL) during endotracheal intubation (ETI) while wearing HazMat PPE.

Post-graduate year (PGY) 1-3 Emergency Medicine residents were randomized to VL or DL while wearing encapsulating PPE. Video laryngoscopy was performed using the GlideScope Cobalt AVL video laryngoscope. The primary outcome measure was time to successful ETI in a high-fidelity simulation mannequin. Three time points were utilized in the analysis: Time 0 (blade at lips), Time 1 (blade removed from lips after endotracheal tube placement), and Time 2 (bag valve mask [BVM] attached to endotracheal tube). Secondary outcome measures were perceived ease of use and feasibility of VL and DL ETI modalities.

Twenty-one of 23 (91.3%) eligible residents participated. Mean time to ETI was 10.0 seconds (SD=5.3 seconds) in the DL group and 7.8 seconds (SD=3.0 seconds) in the VL group (P=.081). Mean times from blade insertion until BVM attachment were 17.4 seconds (SD=6.0 seconds) and 15.6 seconds (SD=4.6 seconds), respectively (P=.30). There were no unsuccessful intubation attempts. Seventeen out of 20 participants (85.0%) perceived VL to be easier to use when performing ETI in PPE. Twelve out of 20 participants (60%) perceived DL to be more feasible in an actual HazMat scenario.

The time to successful ETI was not significantly different between VL and DL. Video laryngoscopy had a greater perceived ease of use, but DL was perceived to be more feasible for use in actual HazMat situations. These findings suggest that both DL and VL are reasonable modalities for use in HazMat situations, and the choice of modality could be based on the clinical situation and provider experience.

Disparities in access to medical care and outcomes of medical treatment related to insurance status are documented. However, little attention has been given to the effect of health care funding status on outcomes in trauma patients.

This study evaluated if adult trauma patients who arrived by air transport to a trauma center had different clinical outcomes based on their health insurance status.

A retrospective analysis was performed of all adult trauma patients arriving by prehospital flight services to a Level I Trauma Center over a 5-year period. Patients were classified as unfunded or funded based on health insurance status. Injury severity scores (ISS) were compared, while the end points evaluated in the study included duration of stay in the intensive care unit (ICU), duration of hospitalization, and mortality.

A total of 1,877 adult patients met inclusion criteria for the study, with 14% (n = 259) classified as unfunded and 86% (n = 1,618) classified as funded. Unfunded patients compared to funded patients had a significantly lower average ISS (12.82 vs 15.56; P < .001) but a significantly higher mortality rate (16.6% vs 10.7%; P < .01) and a 1.54 relative risk of death (95% CI, 1.136-2.098). Neither mean ICU stay (3.44 days vs 4.98 days; P = .264) nor duration of hospitalization (11.18 days vs 13.34 days; P = .382) was significantly different when controlling for ISS.

Unfunded health insurance status is associated with worse outcomes following less significant injury. Further investigation of baseline health disparities for identification and early intervention may improve outcomes. Additionally, these findings may have implications for the health systems of other countries that lack universal health care coverage.

Trauma is a leading cause of morbidity and mortality worldwide, with the majority occurring in low- and middle-income countries (LMICs). Allied health workers are often on the front lines of caring for trauma patients; this is the case in South Sudan, where a system of community health workers (CHWs) and clinical officers (COs) form an essential part of the health care structure. However, curricula for these workers vary, and it is unclear how much these training programs include trauma education.

The CHW training curriculum in South Sudan was reviewed to evaluate the degree to which it incorporates trauma education, according to established guidelines from the World Health Organization (WHO). To the authors’ knowledge, this is the first formal comparison of a CHW curriculum with established WHO trauma guidelines.

The curriculum incorporated a number of essential components of the WHO guidelines; however, the concepts taught were limited in scope. The curriculum only covered about 50% of the content required for basic providers, with major deficiencies being in the management of head and spinal injuries, safety protocols for health care personnel, and in the management of pediatric patients.

The CHW training curriculum lacks the requisite content to provide adequately a basic level of trauma care and requires amending to ensure that all South Sudan citizens receive appropriate treatment. It is recommended that other LMICs review their existing training curricula in order to improve their ability to provide adequate trauma care and to ensure they meet the basic WHO guidelines.
