Bleeding control measures performed by members of the public can prevent trauma deaths. Equipping public spaces with bleeding control kits facilitates these actions. We modeled a mass casualty incident to investigate the effects of public bleeding control kit location strategies.

We developed a computer simulation of a bomb exploding in a shopping mall. We used evidence and expert opinion to populate the model with parameters such as the number of casualties, the public’s willingness to aid, and injury characteristics. Four alternative placement strategies of public bleeding control kits in the shopping mall were tested: co-located with automated external defibrillators (AEDs) separated by 90-second walking intervals, dispersed throughout the mall at 10 locations, located adjacent to 1 exit, located adjacent to 2 exits.

Placing bleeding control kits at 2 locations co-located with AEDs resulted in the most victims surviving (18.2), followed by 10 kits dispersed evenly throughout the mall (18.0). One or 2 kit locations placed at the mall’s main exits resulted in the fewest surviving victims (15.9 and 16.1, respectively).

Co-locating bleeding control kits with AEDs at 90-second walking intervals results in the best casualty outcomes in a modeled mass casualty incident in a shopping mall.

The Super Bowl is one of the biggest annual sporting events that creates unique challenges for public health preparedness. The objective of this brief is to discuss the successes and challenges of the Joint Information Center (JIC) during Super Bowl LVI.

This study analyzed the JIC within 4 realms: pre-activation planning, public safety and alert messaging, communication, and credentialing and access.

Pre-activation planning was not attended by all agencies, which made it difficult for effective communication during the activation period. Innovative platforms and social media themes were successfully deployed to enhance inter-operational communications and public safety messaging. Lastly, delayed credentialing and access to the Super Bowl Stadium decreased the ability to have context to safety preparedness.

This study recommends that many of the JIC’s successes should be translated to future mass-gathering events. Additionally, we urge that all agencies participate during pre-activation and activation periods to enhance safety operations and communications moving forward.

While hospital-related shootings are not common, recent years have demonstrated an increasing trend, especially involving the emergency department (ED). Despite this increase, there remains a lack of effective training for providers for active shooter events. Existing trainings commonly lack active participation, departmental-specific plans, or feasibility.

Sixty-six emergency medicine physicians, nurses, and technicians participated in a two-phased multimodal active shooter training aimed to increase response knowledge and comfort. The initial training phase included a lecture on “Run-Hide-Fight” principles with departmental adaptations, followed by scenario-based discussion, and then safety walkthrough. Months later in the second phase, participants completed an active shooter simulation. An identical knowledge survey was collected before and after each phase along with descriptive analysis. Surveys were compared using paired t-test. Comfort levels were reported on a Likert scale and compared by paired t-test.

Paired t-tests confirmed a statistically significant difference in both active shooter knowledge and comfort levels. Participants showed retention of response knowledge and comfort with implementing response behaviors. Further descriptive analysis demonstrated effective fleeing and barricading, suggesting a real-life gain of knowledge and comfort.

A two-phased, multimodal training design for active shooter response was successful in increasing ED provider active shooter knowledge, comfort, retention, and effective response behaviors.

New York City was the epicenter of the outbreak of the 2019 coronavirus disease (COVID-19) pandemic in the United States. As a large, quaternary care medical center, NYU Langone Medical Center was one of many New York medical centers that experienced an unprecedented influx of patients during this time. Clinical leadership effectively identified, oriented, and rapidly deployed a “COVID Army,” consisting of non-hospitalist physicians, to meet the needs of the patient influx. We share feedback from our providers on our processes and offer specific recommendations for systems experiencing a similar influx in the current and future pandemics.

To assess the experiences and perceived readiness of these physicians (n = 183), we distributed a 32-item survey between March and June of 2020. Thematic analyses and response rates were examined to develop results.

Responses highlighted varying experiences and attitudes of our frontline physicians during an emerging pandemic. Thematic analyses revealed a series of lessons learned, including the need to (1) provide orientations, (2) clarify roles/workflow, (3) balance team workload, (4) keep teams updated on evolving policies, (5) make team members feel valued, and (6) ensure they have necessary tools available.

Lessons from our deployment and assessment are scalable at other institutions.

Qualitative fit testing is a popular method of ensuring the fit of sealing face masks such as N95 and FFP3 masks. Increased demand due to the coronavirus disease 2019 (COVID-19) pandemic has led to shortages in testing equipment and has forced many institutions to abandon fit testing. Three key materials are required for qualitative fit testing: the test solution, nebulizer, and testing hood. Accessible alternatives to the testing solution have been studied. This exploratory qualitative study evaluates alternatives to the nebulizer and hoods for performing qualitative fit testing.

Four devices were trialed to replace the test kit nebulizer. Two enclosures were tested for their ability to replace the test hood. Three researchers evaluated promising replacements under multiple mask fit conditions to assess functionality and accuracy.

The aroma diffuser and smaller enclosures allowed participants to perform qualitative fit tests quickly and with high accuracy.

Aroma diffusers show significant promise in their ability to allow individuals to quickly, easily, and inexpensively perform qualitative fit testing. Our findings indicate that aroma diffusers and homemade testing hoods may allow for qualitative fit testing when conventional apparatus is unavailable. Additional research is needed to evaluate the safety and reliability of these devices.

The completion of a laser safety course remains a core surgical curriculum requirement for otolaryngologists training in the UK. This project aimed to develop a comprehensive laser safety course utilising both technical and non-technical skills simulation.

Otolaryngology trainees and consultants from the West of Scotland Deanery attended a 1-day course comprising lectures, two high-fidelity simulation scenarios and a technical simulation of safe laser use in practice.

The course, and in particular the use of simulation training, received excellent feedback from otolaryngology trainees and consultants who participated. Both simulation scenarios were validated for future use in laser simulation.

The course has been recognised as a laser safety course sufficient for the otolaryngology Certificate of Completion of Training. To the authors’ knowledge, this article represents the first description of using in situ non-technical skills simulation training for teaching laser use in otolaryngology.

Public health preparedness is an ever-evolving area of medicine with the purpose of helping the masses quickly and efficiently. The drive-through clinic (DTC) model allows the distribution of supplies or services while participants remain in their cars. Influenza vaccination is the most common form of DTC and has been utilized successfully in metropolitan areas.

We hypothesized that combining influenza vaccinations and child passenger seat fittings in a DTC format would be both feasible and desired by the community. Each driver was verbally surveyed at each DTC station. The project was a combination of patient survey and observation.

In the inaugural 6-hour DTC session, 86 cars were served and contained 161 children, of which 28 also participated in child passenger seat fittings. The median total clinic time regardless of services rendered was 9.0 minutes (interquartile range [IQR]: 6.0, 14.0 minutes). For those who received only an influenza vaccine, the median total time was 7.5 minutes (IQR: 6.0, 10.0 minutes). For those who received both services, the median total time was 27 minutes (IQR: 22.3, 33.5 minutes) with an average of 1.75 child passenger seat fittings per automobile.

This was a pilot study involving 2 different services using the DTC model and the first of its kind in the literature. The DTC was successful in executing both services without sacrificing speed, convenience, or patient satisfaction. Additional studies are needed to further evaluate the efficacy of the multiple-service DTC model. (Disaster Med Public Health Preparedness. 2017;11:647–651)

Ambulance drivers often travel under stressful conditions at high speed while using vehicles with poor high-speed maneuverability. The occupant safety of ambulance vehicles has not yet been addressed by the automotive safety paradigm; particularly for the rear patient compartment. This study had two objectives: (1) to assess by survey the French Emergency Medical Services (EMS) to determine the layout of the vehicle most often used and the EMS personnel's behavior during transport; and (2) to conduct a crash test to analyze the injuries which may affect EMS personnel and patients in the rear patient compartment.

Firstly, a survey was distributed to the 50 largest metropolitan French EMS programs. Secondly, a crash test was performed with a Mobile Intensive Care Unit (MICU) in conditions closest to reality.

Forty-nine of the 50 biggest metropolitan French EMS programs responded to the survey. This represents 108 French MICUs. During the last three years, 12 of 49 EMS programs (24%) identified at least one accident with an MICU, and six of these 12 (50%) suffered at least one death in those accidents. A crash test using a typical French EMS MICU showed that after impact of a collision, the ambulance was moved more than five meters with major consequences for all passengers. A study-approved human cadaver placed in the position of a potential patient was partially thrown from the stretcher with a head impact. The accelerometric reaction of the anthropomorphic manikin head was measured at 48G.

The crash test demonstrated a lack of safety for EMS personnel and patients in the rear compartment. It would be preferable if each piece of medical equipment were provided with a quick release system resistant to three-dimensional 10G forces. The kinetic changes undergone by the “patient” substitute on the stretcher would probably have an effect of causing injury pathology. This study highlights the need for more research and development in this area.
