Controlling bleeding early in the prehospital and military setting is an extremely important and life-saving skill. Wound clamping is a newly introduced technique that may augment both the effectiveness and logistics of wound packing with any gauze product. As these devices may be inadvertently removed, the potential consequences of such were examined in a simulated, extreme, inadvertent disengagement.
Methods
The wound clamp used was an iTClamp (Innovative Trauma Care; Edmonton, Alberta, Canada) that was applied and forcefully removed (skin-pull) from the skin of both a human cadaver and swine. Sixty skin-pull tests were sequentially performed to measure the pull weight required to remove the device, any potential skin and device damage, how the device failed, and if the device could be re-applied.
Results
Observations of the skin revealed that other than the expected eight small needle holes from device application, no other damage to the skin was sustained in 98.3% of cases. Conversely, of the 60 devices pulled, 93.3% of the devices sustained no damage and all could be re-applied. Four (6.7%) of the devices remained in place despite a maximum pull weight >22lbF (pound-force). The mean pull weights for pin bar pull were (lbF): vertical 9.2 (SD=5.0); perpendicular 2.5 (SD=1.7); and parallel 5.3 (SD=3.1). For the encompassed pull position group, mean pull weights were (lbF): vertical 5.7 (SD=2.3); perpendicular 3.0 (SD=2.5); and parallel 14.5 (SD=3.5). The overall mean for all groups was 6.7 (SD=5.2). The two main reasons that the iTClamp was pulled off were because the friction lock let go or the needles slipped out of one side of the skin due to the angle of the pull.
Conclusion
Inadvertent, forcible removal of the iTClamp created essentially no skin damage seen when the wound clamp was forcibly removed from either cadaver or swine models in a variety of positions and directions. Thus, the risks of deployment in operational environments do not seem to be increased.

Select units in the military have improved combat medic training by integrating their functions into routine clinical care activities with measurable improvements in battlefield care. This level of integration is currently limited to special operations units. It is unknown if regular Army units and combat medics can emulate these successes. The goal of this project was to determine whether US Army combat medics can be integrated into routine emergency department (ED) clinical care, specifically medication administration.
Project Design
This was a quality assurance project that monitored training of combat medics to administer parenteral medications and to ensure patient safety. Combat medics were provided training that included direct supervision during medication administration. Once proficiency was demonstrated, combat medics would prepare the medications under direct supervision, followed by indirect supervision during administration. As part of the quality assurance and safety processes, combat medics were required to document all medication administrations, supervising provider, and unexpected adverse events. Additional quality assurance follow-up occurred via complete chart review by the project lead.
Data
During the project period, the combat medics administered the following medications: ketamine (n=13), morphine (n=8), ketorolac (n=7), fentanyl (n=5), ondansetron (n=4), and other (n=6). No adverse events or patient safety events were reported by the combat medics or discovered during the quality assurance process.
Conclusions
In this limited case series, combat medics safely administered parenteral medications under indirect provider supervision. Future research is needed to further develop this training model for both the military and civilian setting.

Ventilation with a bag valve mask (BVM) is a challenging but critical skill for airway management in the prehospital setting.
Hypothesis
Tidal volumes received during single rescuer ventilation with a modified BVM with supplemental external handle will be higher than those delivered using a standard BVM among health care volunteers in a manikin model.
Methods
This study was a randomized crossover trial of adult health care providers performing ventilation on a manikin. Investigators randomized participants to perform single rescuer ventilation, first using either a BVM modified by addition of a supplemental external handle or a standard unmodified BVM (Spur II BVM device; Ambu; Ballerup, Denmark). Participants performed mask placement and delivery of 10 breaths per minute for three minutes, as guided by a metronome. After a three-minute rest period, they performed ventilation using the alternative device. The primary outcome measure was mean received tidal volume as measured by the manikin (IngMar RespiTrainer model; IngMar Medical; Pittsburgh, Pennsylvania USA). Secondary outcomes included subject device preference.
Results
Of 70 recruited participants, all completed the study. The difference in mean received tidal volume between ventilations performed using the modified BVM with external handle versus standard BVM was 20 ml (95% CI, -16 to 56 ml; P=.28). There were no significant differences in mean received tidal volume based on the order of study arm allocation. The proportion of participants preferring the modified BVM over the standard BVM was 47.1% (95% CI, 35.7 to 58.6%).
Conclusions
The modified BVM with added external handle did not result in greater mean received tidal volume compared to standard BVM during single rescuer ventilation in a manikin model.

The primary goal of this study was to compare paramedic first pass success rate between two different video laryngoscopes and direct laryngoscopy (DL) under simulated prehospital conditions in a cadaveric model.
Methods
This was a non-randomized, group-controlled trial in which five non-embalmed, non-frozen cadavers were intubated under prehospital spinal immobilization conditions using DL and with both the GlideScope Ranger (GL; Verathon Inc, Bothell, Washington USA) and the VividTrac VT-A100 (VT; Vivid Medical, Palo Alto, California USA). Participants had to intubate each cadaver with each of the three devices (DL, GL, or VT) in a randomly assigned order. Paramedics were given 31 seconds for an intubation attempt and a maximum of three attempts per device to successfully intubate each cadaver. Confirmation of successful endotracheal intubation (ETI) was confirmed by one of the six on-site physicians.
Results
Successful ETI within three attempts across all devices occurred 99.5% of the time overall and individually 98.5% of the time for VT, 100.0% of the time for GL, and 100.0% of the time for DL. First pass success overall was 64.4%. Individually, first pass success was 60.0% for VT, 68.8% for GL, and 64.5% for DL. A chi-square test revealed no statistically significant difference amongst the three devices for first pass success rates (P=.583). Average time to successful intubation was 42.2 seconds for VT, 38.0 seconds for GL, and 33.7 for seconds for DL. The average number of intubation attempts for each device were as follows: 1.48 for VT, 1.40 for GL, and 1.42 for DL.
Conclusion
The was no statistically significant difference in first pass or overall successful ETI rates between DL and video laryngoscopy (VL) with either the GL or VT (adult).

This is a case report of a 45-year-old man who reported complete amnesia during the very first kilometer of a 10-km run. He was wearing a heart rate monitor (HRM). The interrogation of his HRM watch showed 200 bpm tachycardia beginning in the first kilometer and increasing up to 220 bpm during the last kilometer. The patient was asked to wear a Holter-monitor (Holter Research Laboratory; Helena, Montana USA) electrocardiogram (ECG) while practicing a training session. This examination allowed for the diagnosis of an adrenergic paroxysmal atrial fibrillation (AF) with an impressive auriculo-ventricular conduction over 260 bpm. This case highlights that non-medical devices, such as connected watches, can be helpful to diagnose arrhythmias.

Traction splinting has been the prehospital treatment of midshaft femur fracture as early as the battlefield of the First World War (1914-1918). This study is the assessment of these injuries and the utilization of a traction splint (TS) in blunt and penetrating trauma, as well as intravenous (IV) analgesia utilization by Emergency Medical Services (EMS) in Miami, Florida (USA).
Methods
This is a retrospective study of patients who sustained a midshaft femur fracture in the absence of multiple other severe injuries or severe physiologic derangement, as defined by an injury severity score (ISS) <20 and a triage revised trauma score (T-RTS)≥10, who presented to an urban, Level 1 trauma center between September 2008 and September 2013. The EMS patient care reports were assessed for physical exam findings and treatment modality. Data were analyzed descriptively and statistical differences were assessed using odds ratios and Z-score with significance set at P≤.05.
Results
There were 170 patients studied in the cohort. The most common physical exam finding was a deformity +/- shortening and rotation in 136 patients (80.0%), followed by gunshot wound (GSW) in 22 patients (13.0%), pain or tenderness in four patients (2.4%), and no findings consistent with femur fracture in three patients (1.7%). The population was dichotomized between trauma type: blunt versus penetrating. Of 134 blunt trauma patients, 50 (37.0%) were immobilized in traction, and of the 36 penetrating trauma victims, one (2.7%) was immobilized in traction. Statistically significant differences were found in the application of a TS in blunt trauma when compared to penetrating trauma (OR=20.83; 95% CI, 2.77-156.8; P <.001). Intravenous analgesia was administered to treat pain in only 35 (22.0%) of the patients who had obtainable IV access. Of these patients, victims of blunt trauma were more likely to receive IV analgesia (OR=6.23; 95% CI, 1.42-27.41; P=.0067).
Conclusion
Although signs of femur fracture are recognized in the majority of cases of midshaft femur fracture, only 30% of patients were immobilized using a TS. Statistically significant differences were found in the utilization of a TS and IV analgesia administration in the setting of blunt trauma when compared to penetrating trauma.

Indoor mold levels typically increase after natural disasters, flooding, and water damage. Eurotium herbariorum is the sexual stage of Aspergillus glaucus.
Case Presentation
A 66-year-old, Japanese male, ex-smoker had been diagnosed with bronchial asthma when he was five years old; he achieved remission at the age of 13 years. He was displaced from his home during the Great East Japan Earthquake on March 11, 2011 and moved to temporary housing in Miyagi Prefecture in June 2011. He experienced the first episode of chest tightness, coughing, and wheezing in February 2012, when he again was diagnosed as having bronchial asthma. Mycofloral surveillance detected high counts of Eurotium in the air of his bedroom, kitchen, and living room, with a maximal fungal count of 163,200 colony-forming units per cubic meter (CFU/m3). Although Cladosporium and Penicillium typically predominate in the indoor air of residential dwellings, only low levels of these organisms were present in the patient’s home. Morphologic identification confirmed the isolates as E. herbariorum. The patient had positive reactions to E. herbariorum in skin prick testing and the presence of antigen-specific precipitating antibodies to E. herbariorum. Computed tomography of the chest in August 2013 revealed central bronchiectasis and bronchial wall thickening. The patient experienced late reactions after provocation testing with E. herbariorum.
Conclusion
This report presents the rare case of a patient who developed allergic bronchopulmonary mycosis (ABPM) due to exposure to E. herbariorum during temporary housing after the Great East Japan Earthquake.

By 2030, road traffic accidents are projected to be the fifth leading cause of death worldwide, with 90% of these deaths occurring in low- and middle-income countries (LMICs). While high-quality, prehospital trauma care is crucial to reduce the number of trauma-related deaths, effective Emergency Medical Systems (EMS) are limited or absent in many LMICs. Although lay providers have long been recognized as the front lines of informal trauma care in countries without formal EMS, few efforts have been made to capitalize on these networks. We suggest that lay providers can become a strong foundation for nascent EMS through a four-fold approach: strengthening and expanding existing lay provider training programs; incentivizing lay providers; strengthening locally available first aid supply chains; and using technology to link lay provider networks.

The Nepal earthquake of 2015 was a major disaster that exacted an enormous toll on human lives and caused extensive damage to the infrastructure of the region. Similar to other developing countries, Nepal has a network of community health workers (CHWs; known as female community health volunteers [FCHVs]) that was in place prior to the earthquake and continues to function to improve maternal and child health. These FCHVs and other community members were responsible, by default, for providing the first wave of assistance after the earthquake.
Hypothesis/Problem
Community health workers such as FCHVs could be used to provide formal relief services in the event of an emergency, but there is a paucity of evidence-based literature on how to best utilize them in disaster risk reduction, preparedness, and response. Data are needed to further characterize the roles that this cadre has played in past disasters and what strategies can be implemented to better incorporate them into future emergency management.
Methods
In March 2016, key-informant interviews, FCHV interviews, and focus group discussions (FGDs) were conducted in Nepali health facilities using semi-structured guides. The audio-recorded data were obtained with the assistance of a translator (Nepali-English), transcribed verbatim in English, and coded by two independent researchers (manually and with NVivo 11 Pro software [QSR International; Melbourne, Australia]).
Results
Across seven different regions, 14 interviews with FCHVs, two FGDs with community women, and three key-informant interviews were conducted. Four major themes emerged around the topic of FCHVs and the 2015 earthquake: (1) community care and rapport between FCHVs and local residents; (2) emergency response of FCHVs in the immediate aftermath of the earthquake; (3) training requested to improve the FCHVs’ ability to manage disasters; and (4) interaction with relief organizations and how to create collaborations that provide aid relief more effectively.
Conclusions
The FCHVs in Nepal provided multiple services to their communities in the aftermath of the earthquake, largely without any specific training or instruction. Proper preparation, in addition to improved collaboration with aid agencies, could increase the capacity of FCHVs to respond in the event of a future disaster. The information gained from this study of the FCHV experience in the Nepal earthquake could be used to inform risk reduction and emergency management policies for CHWs in various settings worldwide.

In recent years, mass-casualty incidents (MCIs) have become more frequent and deadly, while emergency department (ED) crowding has grown steadily worse and widespread. The ability of hospitals to implement an effective mass-casualty surge plan, immediately and expertly, has therefore never been more important. Yet, mass-casualty exercises tend to be highly choreographed, pre-scheduled events that provide limited insight into hospitals’ true capacity to respond to a no-notice event under real-world conditions. To address this gap, the US Department of Health and Human Services (Washington, DC USA), Office of the Assistant Secretary for Preparedness and Response (ASPR), sponsored development of a set of tools meant to allow any hospital to run a real-time, no-notice exercise, focusing on the first hour and 15 minutes of a hospital’s response to a sudden MCI, with the goals of minimizing burden, maximizing realism, and providing meaningful, outcome-oriented metrics to facilitate self-assessment. The resulting exercise, which was iteratively developed, piloted at nine hospitals nationwide, and completed in 2015, is now freely available for anyone to use or adapt. This report demonstrates the feasibility of implementing a no-notice exercise in the hospital setting and describes insights gained during the development process that might be helpful to future exercise developers. It also introduces the use of ED “immediate bed availability (IBA)” as an objective, dynamic measure of an ED’s physical capacity for new arrivals.

The Public Health England (PHE; United Kingdom) Real-Time Syndromic Surveillance Team (ReSST) currently operates four national syndromic surveillance systems, including an emergency department system. A system based on ambulance data might provide an additional measure of the “severe” end of the clinical disease spectrum. This report describes the findings and lessons learned from the development and preliminary assessment of a pilot syndromic surveillance system using ambulance data from the West Midlands (WM) region in England.
Hypothesis/Problem
Is an Ambulance Data Syndromic Surveillance System (ADSSS) feasible and of utility in enhancing the existing suite of PHE syndromic surveillance systems?
Methods
An ADSSS was designed, implemented, and a pilot conducted from September 1, 2015 through March 1, 2016. Surveillance cases were defined as calls to the West Midlands Ambulance Service (WMAS) regarding patients who were assigned any of 11 specified chief presenting complaints (CPCs) during the pilot period. The WMAS collected anonymized data on cases and transferred the dataset daily to ReSST, which contained anonymized information on patients’ demographics, partial postcode of patients’ location, and CPC. The 11 CPCs covered a broad range of syndromes. The dataset was analyzed descriptively each week to determine trends and key epidemiological characteristics of patients, and an automated statistical algorithm was employed daily to detect higher than expected number of calls. A preliminary assessment was undertaken to assess the feasibility, utility (including quality of key indicators), and timeliness of the system for syndromic surveillance purposes. Lessons learned and challenges were identified and recorded during the design and implementation of the system.
Results
The pilot ADSSS collected 207,331 records of individual ambulance calls (daily mean=1,133; range=923-1,350). The ADSSS was found to be timely in detecting seasonal changes in patterns of respiratory infections and increases in case numbers during seasonal events.
Conclusions
Further validation is necessary; however, the findings from the assessment of the pilot ADSSS suggest that selected, but not all, ambulance indicators appear to have some utility for syndromic surveillance purposes in England. There are certain challenges that need to be addressed when designing and implementing similar systems.

During a refugees’ mass-gathering incident in Kos Island, Greece, Médecins Sans Frontières (MSF; Brussels, Belgium) teams provided emergency medical care. A case report of the event focusing on difficulties encountered by the interpreters during triage and emergency response was prepared.
Methods
Data collected during the event were reviewed from the patient’s register and qualitative interviews were obtained from the MSF interpreters involved in the response. In addition, a description of the event and a literature review were included.
Results
Total consultations were 49 patients, mainly from Syria, with an average age of 25 years. During triage, 20 patients were tagged green with only minor injuries; 11 patients were tagged yellow, mostly due to heat exhaustion, but also a hypertensive crisis, a diabetic, a pregnant woman with abdominal pain, and a peptic ulcer exacerbation. The remaining 18 patients were tagged red and diagnosed with heat syncope, except from a case of epileptic seizures and an acute chest pain patient. Interpreters were insufficient in number to accompany each doctor and every nurse providing care during the event. In addition, they were constantly disturbed by both refugees and fellow medical team members demanding their service. Interpreters had to triage and prioritize where to go and for whom to interpret.
Conclusion
Interpreters are an integral part of a proper refugee reception system. They should be included in authorities planning where mass gatherings of refugees are expected. Appropriate training may be needed for interpreters to develop skills useful in mass gatherings and similar prehospital settings in order to better coordinate with the medical team.

Sudden onset disasters (SODs) have affected over 1.5 billion of the world’s population in the past decade. During the same time, developing nations have faced a sustained increase in the burden of non-communicable disease (NCD) with extra pressure placed on health systems. The combined increase in SODs and the NCD epidemic facing the world’s most disaster-prone nations will present new challenges to emergency medical teams (EMTs) during disaster response. This report details the experience as an EMT during the Typhoon Haiyan disaster of 2013, with particular reference to the challenges of diabetic management in a surgical field hospital. The incidence of diabetes in this surgical cohort exceeded that of the population by a factor of four. The steps to prepare for and treat diabetes in the field provide a useful model for the management of NCD in the deployed field hospital environment after a disaster.

In early 2015, a patient from a cluster of cases of Ebola Virus Disease (EVD) in Monrovia, Liberia traveled to a rural village in Margibi County, potentially exposing numerous persons. The patient died in the village and post-mortem testing confirmed Ebola Virus infection.
Problem
The Margibi County Health Team (CHT; Kakata, Margibi, Liberia) needed to prevent further transmission of EVD within and outside of the affected villages, and they needed to better understand the factors that support or impede compliance with measures to stop the spread of EVD.
Methods
In February-March 2015, the Margibi CHT instituted a 21-day quarantine and active monitoring for two villages where the patient had contact with numerous residents, and a 21-day active monitoring for five other villages where the patient had possible contact with an unknown number of persons. One contact developed EVD and quarantine was extended an additional 12 days in one village. In April 2015, the Margibi CHT conducted a household-based EVD knowledge, attitudes, and practices (KAP) survey of the seven villages. From April 24-29, 2015, interview teams approached every household in the seven villages and collected information on demographics, knowledge of EVD, attitudes about quarantine to prevent the spread of EVD, and their quarantine experiences and practices. Descriptive statistics were calculated.
Results
One hundred fifteen interviews were conducted, representing the majority of the households in the seven villages. Most (99%) correctly identified touching an infected person’s body fluids and contact with the body of someone who has died from EVD as transmission routes. However, interviewees sometimes incorrectly identified mosquito bites (58%) and airborne spread (32%) as routes of EVD transmission, and 72% incorrectly identified the longest EVD incubation period as ≤seven days. Eight of 16 households in the two quarantined villages (50%) reported times when there was not enough water or food during quarantine. Nine of 16 (56%) reported that a household member had illnesses or injuries during quarantine; of these, all (100%) obtained care from a clinic, hospital, or Ebola treatment unit (ETU).
Conclusion
Residents’ knowledge of EVD transmission routes and incubation period were suboptimal. Public health authorities should consider assessing residents’ understanding of Ebola transmission routes and effectively educate them to ensure correct understanding. Quarantined residents should be provided with sufficient food, water, and access to medical care.
