Objective: The role of emergency medical services (EMS) preparedness in mass casualty incidents (MCIs) is crucial. MCIs are increasing worldwide, and EMS must enhance preparedness for them. For this purpose, the main components of EMS preparedness should be identified. This study aimed to describe the components of EMS preparedness in response to MCIs.

Design and setting: This systematic review was conducted based on the Preferred Reporting Item for Systematic Reviews and Meta-analyses guideline. The articles published from January 1970 to February 2022 were searched to discover the main components of EMS preparedness in MCIs. The electronic databases including PubMed, Cochrane Library, Scopus, Science Direct, and ProQuest were searched using predetermined keywords. Ten articles were selected and included in this review.

Results: After reviewing the articles, we identified the components of EMS preparedness in MCIs. Accordingly, 16 main components were extracted and classified into four categories, ie, individual improvement, group improvement, resources, and operations.

Conclusion: MCIs are so complicated that they require adequate prehospital preparedness. This study described the components of EMS preparedness in MCIs. The authorities in EMS will benefit from this framework in planning and responding to MCIs.

Introduction and objectives: Emergency medical services (EMS) is an invaluable healthcare resource, providing life-saving care in the prehospital setting. During the COVID-19 pandemic, there have been concerns that healthcare resources, including EMS, would be overwhelmed by the potential surge in critically ill patients. This study seeks to determine the impact of the COVID-19 pandemic on EMS utilization in the state of Maryland.

Methods: A retrospective review of data from the Maryland Emergency Medical Services Data System was performed. EMS call volumes were compared from March 1 to August 31 in the years 2018, 2019, and 2020. In addition, adult cases from the three time periods that contained an EMS impression of stroke, cardiac arrest, asthma, traumatic injury, ST elevation myocardial infarction (STEMI), sepsis, and overdose were also analyzed.

Results: There was a significant decrease in overall EMS call volumes in the state of Maryland in the first 6 months of 2020 compared to the prior 2 years. While the total number of calls decreased, a higher proportion of patients in 2020 had EMS impressions of cardiac arrest, STEMI, stroke, and traumatic injury compared to the previous 2 years. Additionally, there was an increase in termination of resuscitation for out of hospital cardiac arrest.

Conclusion: In the state of Maryland, overall call volumes decreased, but the proportion of EMS patients with time-sensitive illnesses increased during the COVID-19 pandemic.

Most chemical or biological decontamination protocols have been driven by the need for fast and efficient methods that are relatively safe and easy to implement. As such, the focus has primarily been toward "general" environments-those in which water is readily available, and the ambient conditions are amenable to such techniques. Some of these include water showers and/or sprays with chemical decontaminants, eg, soapy water or diluted bleach. However, there exist some scenarios in which water-based decontamination methods are not desirable. These include such operational environments as arid regions (water scarcity), specialized operations (decontamination method must be low volume/weight), and cold weather (freezing risk). This study focuses on the cold weather challenge: identification of common methods for readily available decontamination and evaluation of their respective efficacies. Methods evaluated include wiping (with wet and dry wipes), blotting with moistened wipes, vacuuming, and the application and removal of adhesive tape. Results demonstrate that vacuuming and blotting (without overlapping targeted regions) are generally less effective than other wiping, blotting, and adhesive tape-based measures at removing bacteria from surfaces.

Objective: To identify physical and verbal descriptors that have the highest concordance between parents/guardians and a research team member to improve reunification during a disaster when a child arrives at the emergency department separated from their family.

Methods: Parent and child pairs were recruited between February 2020 and March 2020. Each parent and research team member simultaneously recorded the child's physical characteristics and clothing items. Verbal children were asked personally identifying questions. An inter-rater reliability Cohen's κ determined percent agreement between each researcher and parent/child pair.

Results: In total, 98 parent/child pairs participated. Child's gender, eye color measured as brown versus not brown eyes, and race had the highest concordance (κ = 0.92, 0.85, and 0.84, respectively; p < .001 for all). Skin color and all hair descriptors had low concordance. All or almost all verbal children correctly identified that they have a pet and a favorite stuffed animal or blanket (100 and 98.6 percent, respectively).

Discussion: Only apparent age, gender, race, and general eye color (brown versus nonbrown) had strong concordance between each researcher and parent/child pair. Other descriptors such as hair color, texture, length, and detailed eye color were discordant. Additionally, several pieces of personal information, such as a pet, could expedite reunification of verbal children.

Conclusion: Not all physical characteristics are likely to be useful in accurately identifying a child, and some personal information may aid in reunification. Using the most concordant information should allow for more accurate and rapid reunification of children and their caregivers during disasters.

Objective: Hospitals are the basic infrastructure for disaster response. While they themselves are exposed to disasters, they also play an important role during the disaster response period. Therefore, they are expected to be able to maintain their performance during and immediately after disasters. The aim of this study is to discover strategies to improve the hospital disaster risk management.

Design: This study is a systematic qualitative study with thematic analysis. Data sources including Persian and international databases were searched using the "Hospital, Disaster, Risk management, Risk reduction, Improvement, and Strategy" keywords and their combinations of them. The search time period ranged from January 2010 to January 2020. Data were extracted by two independent arbitrators for qualitative thematic analysis.

Results: In total, 889 articles and documents were retrieved. Of which, 166 articles were deleted due to duplication, 436 articles did not meet the objectives of the research, and 263 articles did not meet the eligibility criteria and were deleted. Finally, 24 articles were included in the study. After thematic analysis, 33 subthemes were obtained and classified into five themes of organizational-managerial strategies, preventive and risk reduction strategies, preparedness strategies, response strategies, and recovery strategies. Not all articles discuss all categories.

Conclusion: Applying strategies to improve the hospital disaster risk management resulting from this study can be useful in improving the preparedness of hospitals in the face of disasters.

Objective: To describe trends in prehospital presentations of critical medical and trauma conditions during the COVID-19 pandemic using prehospital and emergency department (ED) care activations.

Methods: Observational analysis of ED care activations in a tertiary, urban ED between March 10, 2020 and September 1, 2020 was compared to the same time periods in 2018 and 2019. ED care activations for critical medical conditions were classified based on clinical indication: undifferentiated medical, trauma, or stroke.

Main outcome: The primary outcomes were the number of patients presenting from the prehospital setting with specified ED activation criteria, total ED volume, ambulance arrival volume, and volume of COVID-19 hospital admissions. Locally weighted scatterplot smoothing curves were used to visually display our results.

Results: There were 1,461 undifferentiated medical activations, 905 stroke activations, and 1,478 trauma activations recorded, representing absolute decreases of 11.3, 28.1, and 20.3 percent, respectively, relative to the same period in 2019, coinciding with the declaration of a public health emergency in Connecticut. For all three types of presentation, post-peak spikes in activations were observed in early May, approximately two weeks after our health system in Connecticut reached its peak number of COVID-19 hospitalizations-eg, undifferentiated medical activations: increase in 280 percent, n = 140 from 2019, p < 0.0001-and declined thereafter, reaching a nadir in early June 2020.

Conclusions: After the announcement of public health measures to mitigate COVID-19, ED care activations declined in a large Northeast academic ED, followed by post-peak surges in activations as COVID- 19 cases decreased.

Objective: Sporting events often constitute mass gatherings (MGs) featuring large crowds of spectators and participants. Our objective is to understand the current state of emergency preparedness for sporting events by examining past MG sporting events to evaluate mitigation, preparedness, response, and recovery against chemical, biological, radiological, nuclear, and explosive (CBRNE) events.

Methods: In accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature review was carried out among 10 literature databases. The quality and risk of bias in each reviewed publication was assessed using the Mixed Methods Appraisal Tool.

Results: A total of 5,597 publications were identified. Of these, 81 papers were selected for full text reads and 25 publications were accepted. The included articles documented sporting events worldwide, ranging from incidents occurring from 1972 to 2020. Cross-cutting themes found in best practices and recommendations were strategic communication, surveillance, planning and preparedness, and training and response.

Conclusion: More evidence-based guidelines are needed to ensure best practices in response and recovery for CBRNE incidents at sporting events. Public health risks as well as implementation barriers and opportunities to prepare for potential CBRNE threats at sporting event MGs require further investigation.

Introduction: Military firefighters are the first responders in the event of a chemical, biological, radiation, and nuclear (CBRN) event in the Marseille area. They receive initial training to intervene safely in a CBRN context. We wanted to evaluate the use of CBRN personal protective equipment (PPE) at a distance from this training.

Method: A prospective observational bicentric descriptive study on 20 operational firefighters operating on rescue and emergency vehicles. Two PPE dressing sessions, separated by 3 months, were evaluated and timed. A reminder of the correct procedure was given by the investigator after the first dressing.

Results: On average, 60.5 percent of the steps were correctly performed during the first dressing and 83 percent during the second dressing. Between the two dressings, there was a significant improvement (p < 0.01) in the team verification of the dressing and the chronological order of the dressing as well as the actions to be taken before dressing (remembering to make oneself comfortable, to urinate, to drink). The second dressing is on average 21 seconds faster than the first. Professional training and exercise experience of the firefighters in CBRN improve the success and speed of dressing in the absence of a prior reminder.

Conclusion: Shorter and more frequent training and exercises, which simulate real-life situations for firefighters, lead to safer, more competent and faster donning of PPE.

During periods of civil unrest, emergency medical services (EMSs) clinicians will be called upon to provide care to those impacted, including those who are actively instigating violence. Working during periods of civil unrest poses significant operational and security challenges to EMS leadership and clinicians. This review provides best practices for EMS operating during periods of civil unrest through analysis of after action reports from Baltimore, Maryland; Charlottesville, North Carolina; Minneapolis, Minnesota; and Washington, DC.
