Hazardous material (HAZMAT) protocols require health care providers to wear personal protective equipment (PPE) when caring for contaminated patients. Multiple levels of PPE exist (level D - level A), providing progressively more protection. Emergent endotracheal intubation (ETI) of victims can become complicated by the cumbersome nature of PPE.

The null hypothesis was tested that there would be no difference in time to successful ETI between providers in different types of PPE.

This randomized controlled trial assessed time to ETI with differing levels of PPE. Participants included 18 senior US Emergency Medicine (EM) residents and attendings, and nine US senior Anesthesiology residents. Each individual performed ETI on a mannequin (Laerdal SimMan Essential; Stavanger, Sweden) wearing the following levels of PPE: universal precautions (UP) controls (nitrile gloves and facemask with shield); partial level C (PC; rubber gloves and a passive air-purifying respirator [APR]); and complete level C (CC; passive APR with an anti-chemical suit). Primary outcome measures were the time in seconds (s) to successful intubation: Time 1 (T1) = inflation of the endotracheal tube (ETT) balloon; Time 2 (T2) = first ventilation. Data were reported as medians with Interquartile Ranges (IQR, 25%-75%) or percentages with 95% Confidence Intervals (95%, CI). Group comparisons were analyzed by Fisher’s Exact Test or Kruskal-Wallis, as appropriate (alpha = 0.017 [three groups], two-tails). Sample size analysis was based upon the power of 80% to detect a difference of 10 seconds between groups at a P = .017; 27 subjects per group would be needed.

All 27 participants completed the study. At T1, there was no statistically significant difference (P = .27) among UP 18.0s (11.5s-19.0s), PC 21.0s (14.0s-23.5s), or CC 17.0s (13.5s-27.5s). For T2, there was also no significant (P = .25) differences among UP 24.0s (17.5s-27.0s), PC 26.0s (21.0s-32.0s), or CC 24.0s (19.5s-33.5s).

There were no statistically significant differences in time to balloon inflation or ventilation. Higher levels of PPE do not appear to increase time to ETI.

It remains unclear which mass-casualty incident (MCI) triage tool best predicts outcomes for child disaster victims.

The primary objective of this study was to compare triage outcomes of Simple Triage and Rapid Treatment (START), modified START, and CareFlight in pediatric patients to an outcomes-based gold standard using the Criteria Outcomes Tool (COT). The secondary outcomes were sensitivity, specificity, under-triage, over-triage, and overall accuracy at each level for each MCI triage algorithm.

Singleton trauma patients under 16 years of age with complete prehospital, emergency department (ED), and in-patient data were identified in the 2007-2009 National Trauma Data Bank (NTDB). The COT outcomes and procedures were translated into ICD-9 procedure codes with added timing criteria. Gold standard triage levels were assigned using the COT based on outcomes, including mortality, injury type, admission to the hospital, and surgical procedures. Comparison triage levels were determined based on algorithmic depictions of the three MCI triage tools.

A total of 31,093 patients with complete data were identified from the NTDB. The COT was applied to these patients, and the breakdown of gold standard triage levels, based on their actual clinical outcomes, was: 17,333 (55.7%) GREEN; 11,587 (37.3%) YELLOW; 1,572 (5.1%) RED; and 601 (1.9%) BLACK. CareFlight had the best sensitivity for predicting COT outcomes for BLACK (83% [95% confidence interval, 80%-86%]) and GREEN patients (79% [95% CI, 79%-80%]) and the best specificity for RED patients (89% [95% CI, 89%-90%]).

Among three prehospital MCI triage tools, CareFlight had the best performance for correlating with outcomes in the COT. Overall, none of three tools had good test characteristics for predicting pediatric patient needs for surgical procedures or hospital admission.

Injury patterns are closely related to changes in behavior. Pandemics and measures undertaken against them may cause changes in behavior; therefore, changes in injury patterns during the coronavirus disease 2019 (COVID-19) outbreak can be expected when compared to the parallel period in previous years.

The aim of this study was to compare injury-related hospitalization patterns during the overall national lockdown period with parallel periods of previous years.

A retrospective study was completed of all patients hospitalized from March 15 through April 30, for years 2016-2020. Data were obtained from 21 hospitals included in the national trauma registry during the study years. Clinical, demographic, and circumstantial parameters were compared amongst the years of the study.

The overall volume of injured patients significantly decreased during the lockdown period of the COVID-19 outbreak, with the greatest decrease registered for road traffic collisions (RTCs). Patients’ sex and ethnic compositions did not change, but a smaller proportion of children were hospitalized during the outbreak. Many more injuries were sustained at home during the outbreak, with proportions of injuries in all other localities significantly decreased. Injuries sustained during the COVID-19 outbreak were more severe, specifically due to an increase in severe injuries in RTCs and falls. The proportion of intensive care unit (ICU) hospitalizations did not change, however more surgeries were performed; patients stayed less days in hospital.

The lockdown period of the COVID-19 outbreak led to a significant decrease in number of patients hospitalized due to trauma as compared to parallel periods of previous years. Nevertheless, trauma remains a major health care concern even during periods of high-impact disease outbreaks, in particular due to increased proportion of severe injuries and surgeries.

Although first responders (FRs) represent a high-risk group for exposure, little information is available regarding their risk of coronavirus disease 2019 (COVID-19) infection. The purpose of the current study was to determine the serological prevalence of past COVID-19 infection in a cohort of municipal law enforcement (LE) and firefighters (FFs).

Descriptive analysis of a de-identified data reporting Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) immunoglobulin G (IgG), or COR2G, serology results for municipal FRs. As part of the serology process, FRs were surveyed for COVID-19-like symptoms since February 2020 and asked to report any prior COVID-19 nasal swab testing. Descriptive statistics and two-sided Chi Square tests with Yates correction were used to compare groups.

Of 318 FRs, 225 (80.2%) underwent serology testing (LE: 163/207 [78.7%]; FF: 92/111 [82.9%]). The prevalence of positive serology for all FRs tested was 3/255 (1.2%). Two LE (1.2%) and one FF (1.1%) had positive serology (P = 1.0). Two hundred and twenty-four FRs responded to a survey regarding prior symptoms and testing. Fifty-eight (25.9%) FRs (44 LE; 14 FFs) reported the presence of COVID-19-like symptoms. Of these, only nine (15.5%) received reverse transcriptase – polymerase chain reaction (RT-PCR) testing; none were positive. Two of the three FRs with positive serology reported no COVID-19-like symptoms and none of these responders had received prior nasal RT-PCR swabs. The overall community positive RT-PCR rate was 0.36%, representing a three-fold higher rate of positive seroprevalence amongst FRs compared with the general population (P = .07).

Amongst a cohort of municipal FRs with low community COVID-19 prevalence, the seroprevalence of SARS-CoV-19 IgG Ab was three-fold greater than the general community. Two-thirds of positive FRs reported a lack of symptoms. Only 15.5% of FRs with COVID-19-like symptoms received RT-PCR testing. In addition to workplace control measures, increased testing availability to FRs is critical in limiting infection spread and ensuring response capability.

While suicide bombings in the context of warfare have existed throughout history, there was an exponential rise in such attacks in the decade following the initiation of the War on Terror. The health care implications of such attacks are a growing concern across the emergency response sector, and this study is an epidemiological examination of all terrorism-related bombings sustained from 1970-2019, comparing the rates of fatal injuries (FI) and non-fatal injuries (NFI) between suicide bombing attacks (SBA) versus non-suicide bombing attacks (NSBA).

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD database was downloaded and searched using the internal database search functions for all events that occurred from January 1, 1970 - December 31, 2019. Bombing/explosion as a primary “attack type” and explosives as a primary “weapon type” were selected for the purpose of this study, and events were further sub-classified as either “suicide attack” or “non-suicide attack.” Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

There were 82,217 bombing/explosion terrorist attacks using explosives documented during the study period with 135,807 fatalities and 352,500 NFI.

A total of 5,416 events (6.59% of all events) were sub-classified as SBA causing 52,317 FI (38.52% of all FI) and 107,062 NFI (30.37% of all NFI).

Mean SBA FI was 9.66 per event and mean SBA NFI was 19.77 per event compared to a mean NSBA FI of 1.09 per event and mean NSBA NFI of 3.20 per event.

Suicide bombing attacks are a unique terrorist methodology that can inflict wide-spread psychological damage as well as significantly higher death and injury tolls when compared to more traditional NSBA. They have been increasing in popularity amongst terrorist organizations and groups, and Counter-Terrorism Medicine (CTM) specialists need to be aware of the unique injury patterns and potential risk mitigation strategies associated with SBA depending on the target type, location, and gender of the perpetrator.

Hurricane Harvey (2017) forced the closure of hemodialysis centers across Harris County, Texas (USA) disrupting the provision of dialysis services. This study aims to estimate the percentage of hemodialysis clinics flooded after Harvey, to identify the proportion of such clinics located in high-risk flood zones, and to assess the sensitivity of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) for estimation of flood risk.

Data on 124 hemodialysis clinics in Harris County were extracted from Medicare.gov and geocoded using ArcGIS Online. The FIRMs were overlaid to identify the flood zone designation of each hemodialysis clinic.

Twenty-one percent (26 of 124) of hemodialysis clinics in Harris County flooded after Harvey. Of the flooded clinics, 57.7% were in a high-risk flood zone, 30.8% were within 1km of a high-risk flood zone, and 11.5% were not in or near a high-risk flood zone. The FIRMs had a sensitivity of 58%, misidentifying 42% (11 of 26) of the clinics flooded.

Hurricanes are associated with severe disruptions of medical services, including hemodialysis. With one-quarter of Harris County in the 100-year floodplain, projected increases in the frequency and severity of disasters, and inadequate updates of flood zone designation maps, the implementation of new regulations that address the development of hemodialysis facilities in high-risk flood areas should be considered.

On September 20, 2017, Hurricane Maria, a Category 4 hurricane, swept across Puerto Rico (PR), wreaking devastation to PR’s power, water, and health care infrastructure. To address the imminent humanitarian crisis, the US government mobilized Federal Medical Shelters (FMS) to serve the needs of hurricane victims. This study’s objective was to provide a description of the patients seeking emergency care at FMS and the changes in their needs over time.

This retrospective, cross-sectional study included all patients presenting to the FMS Manatí from October 6, two weeks after Hurricane Maria’s landfall, to November 2, 2017. Categories were created to catalogue the nature of new acute medical issues by patients presenting to the Shelter. Descriptive, graphical analyses were performed to assess changes to presenting complaints over time, and by age groups defined as infant (age ≤1 years), child (1 year < age ≤10 years), adolescent (10 years < age ≤ 25 years), and adult (age > 25 years).

Over the 30-day period, 5,268 patients were seen in the FMS seeking medical care (average 188.1 patients per day), spending less than five hours in the facility. The distribution of patients’ age was bimodal: the first peak at one year and the second at age 50. The most common patient complaint was infection (38.8%), then musculoskeletal (MSK) complaints (11.8%) and management of chronic medical conditions (11.8%). The proportion of patients presenting with chronic disease complaints declined over the course of the period of observation (21.4% on Day 4 to 8.0% on Day 30) while the proportion of patients presenting with infection increased (31.0% on Day 4 to 48.6% on Day 30). Infection complaints were highest in all age groups, but most in infxants (80.2%), while MSK and chronic disease complaints were highest in adults (14.9% and 14.9%, respectively).

Infection treatment and chronic disease management were important medical needs facing patients seeking care at FMS Manatí after Hurricane Maria. These findings suggest that basic needs related to sanitation and shelter remained important weeks after the hurricane, and a focus on access to medications, infection control, and injury prevention/management after a disaster needs to be prioritized during disaster response.

Disaster impact databases are important resources for informing research, policy, and decision making. Therefore, understanding the underpinning methodology of data collection used by the databases, how they differ, and quality indicators of the data recorded is essential in ensuring that their use as reference points is valid.

The Australian Disaster Resilience Knowledge Hub (AIDRKH) is an open-source platform supported by government to inform disaster management practice. A comparative descriptive review of the Disaster Mapper (hosted at AIDRKH) and the international Emergency Events Database (EM-DAT) was undertaken to identify differences in how Australian disasters are captured and measured.

The results show substantial variation in identification and classification of disasters across hazard impacts and hazard types and a lack of data structure for the systematic reporting of contextual and impact variables.

These differences may have implications for reporting, academic analysis, and thus knowledge management informing disaster prevention and response policy or plans. Consistency in reporting methods based on international classification standards is recommended to improve the validity and usefulness of this Australian database.

Cultural awareness is an important part of organizational success when interacting with multiple cultures. Research has shown a dearth of standardized cultural awareness training programs for non-governmental humanitarian organization staff.

This study aims to develop an expert-consensus set of cultural awareness competencies as the basis for development of humanitarian staff cultural awareness trainings.

A modified Delphi process was selected. The first round of surveys collected a list of cultural awareness competencies from experts in the fields of non-governmental organization (NGO) operations and cultural awareness education and research. This collated list of competencies was then used as the basis of a survey obtaining ratings by the group on a five-point Likert scale. Competencies which achieved an average rating of 4.0 or higher were considered to be “important” for inclusion in future training programs.

A total of 67.9% of contacted experts agreed to participate, with 84.2% of those completing all rounds of the survey. This group developed a list of ten competencies, including: Cultural Awareness/Sensitivity and Intercultural Communication; Cultural Intelligence; Unconscious Bias/Diversity Awareness; a Universal Declaration of Ethical Principles; Gender and Lesbian, Gay, Bisexual, Transgender, Queer, and Other Sexual Identities (LGBTQ+) Issues and Safety; Analytical and Critical Thinking Skills; Negotiation; Program Mission; Power Dynamics; and Empathy.

This study defined a set of ten expert-consensus cultural awareness competencies which can be a basis for future NGO staff training. Future work can both use these competencies to create educational programs and further define and expand the set of competencies based on analyses of their implementation.

The United States (US) is ranked 22nd on the Global Terrorism Index (2019), a scoring system of terrorist activities. While the global number of deaths from terrorism over the past five years is down, the number of countries affected by terrorism is growing and the health care repercussions remain significant. Counter-Terrorism Medicine (CTM) is rapidly emerging as a necessary sub-specialty, and this study aims to provide the epidemiological context over the past decade supporting this need by detailing the unique injury types responders are likely to encounter and setting the stage for the development of training programs utilizing these data.

The Global Terrorism Database (GTD) was searched for all attacks in the US from 2008-2018. Attacks met inclusion criteria if they fulfilled the three terrorism-related criteria as set by the GTD. Ambiguous events were excluded when there was uncertainty as to whether the incident met all of the criteria for inclusion in the GTD. The grey literature was reviewed, and each event was cross-matched with reputable international and national newspaper sources online to confirm or add details regarding weapon type used and, whenever available, details of victim and perpetrator fatalities and injuries.

In total, 304 events were recorded during the period of study. Of the 304 events, 117 (38.5%) used incendiary-only weapons, 80 (26.3%) used firearms as their sole weapon, 55 (18.1%) used explosives, bombs, or dynamite (E/B/D), 23 (7.6%) were melee-only, six (2.0%) used vehicles-only, four (1.3%) were chemicals-only, two (0.7%) used sabotage equipment, two (0.7%) were listed as “others,” and one (0.3%) used biological weapon. There was no recorded nuclear or radiological weapon use. In addition, 14 (4.6%) events used a mix of weapons.

In the decade from 2008 through 2018, terrorist attacks on US soil used weapons with well-understood injury-causing modalities. A total of 217 fatal injuries (FI) and 660 non-fatal injuries (NFI) were sustained as a result of these events during that period.

Incendiary weapons were the most commonly chosen methodology, followed by firearms and E/B/D attacks. Firearm events contributed to a disproportionality high fatality count while E/B/D events contributed to a disproportionally high NFI count.

During the world-wide coronavirus disease 2019 (COVID-19) outbreak, there is an urgent need to rapidly increase the readiness of hospitals. Emergency departments (EDs) are at high risk of facing unusual situations and need to prepare extensively in order to minimize risks to health care providers (HCPs) and patients. In situ simulation is a well-known method used in training to detect system gaps that could threaten safety.

One objective is to identify gaps, test hospital systems, and inform necessary modifications to the standard processes required by patients with COVID-19 presenting at the hospital. The other objective is to improve ED staff confidence in managing such patients, and to increase their skills in basic and advanced airway management and proper personal protective equipment (PPE) techniques.

This is a quasi-experimental study in which 20 unannounced mock codes were carried out in ED resuscitation and isolation rooms. A checklist was designed, validated, and used to evaluate team performances in three areas: donning, basic and advanced airway skills, and doffing. A pre- and post-intervention survey was used to evaluate staff members’ perceived knowledge of ED procedures related to COVID-19 and their airway management skills.

A total of 20 mock codes were conducted in the ED. Overall, 16 issues that posed potential harm to staff or patients were identified and prioritized for immediate resolution. Approximately 57.4% of HCPs felt comfortable dealing with suspected/confirmed, unstable COVID-19 cases after mock codes, compared with 33.3% beforehand (P = .033). Of ED HCPs, 44.4% felt comfortable performing airway procedures for suspected/confirmed COVID-19 cases after mock codes compared with 29.6% beforehand. Performance of different skills was observed to be variable following the 20 mock codes. Skills with improved performance included: request of chest x-ray after intubation (88.0%), intubation done by the most experienced ED physician (84.5%), and correct sequence and procedure of PPE (79.0%).

Mock codes identified significant defects, most of which were easily fixed. They included critical equipment availability, transporting beds that were too large to fit through doors, and location of biohazard bins. Repeated mock codes improved ED staff confidence in dealing with patients, in addition to performance of certain skills. In situ simulation proves to be an effective method for increasing the readiness of the ED to address the COVID-19 pandemic and other infection outbreaks.

Some studies in countries affected by the coronavirus disease of 2019 (COVID-19) pandemic have shown that the missions of Emergency Medical Service (EMS) have changed during the COVID-19 pandemic, and the rate of death and out-of-hospital cardiac arrest (OHCA) has been increased due to the direct and indirect effects of COVID-19.

The aim of this study was to determine the effect of the COVID-19 pandemic on the process of EMS missions, death, and OHCA.

This cross-sectional study was performed in Tehran, Iran. All conducted missions in the first six months of the three consecutive solar years of March 21 until September 22 of 2018-2020, which were registered in the registry bank of the Tehran EMS center, were assessed and compared. Based on the opinion of experts, the technician’s on-scene diagnoses were categorized into 14 groups, and then death and OHCA cases were compared.

In this study, the data of 1,050,376 missions performed in three study periods were analyzed. In general, the number of missions in 2020 was 17.83% fewer than that of 2019 (P < .001); however, the number of missions in 2019 was 30.33% more than that of 2018. On the other hand, the missions of respiratory problems, cardiopulmonary arrest, infectious diseases, and poisoning were increased in 2020 compared to that of 2019. The raw number of OHCA and death cases respectively in 2018, 2019, and 2020 were 25.0, 22.7, and 28.6 cases per 1,000 missions. Of all patients who died in 2020, 4.9% were probable/confirmed COVID-19 cases. The history of heart disease, hypertension, diabetes, and respiratory disease in patients in 2020 was more frequent than that of the other two years.

This study showed that the number of missions in the Tehran EMS in 2020 were decreased compared to that of 2019, however the number of missions in 2019 was more than that of 2018. Respiratory problems, infectious diseases, poisoning, death, and OHCA were increased compared to the previous two years and cardiovascular complaints, neurological problems, and motor vehicle collisions (MVCs) in 2020 were fewer than that of the other two years

Mass-casualty incidents (MCIs), specifically incidents with chemical, biological, radiological, and nuclear agents (CBRN) or terrorist attacks, challenge medical coordination, rescue, availability, and adequate provision of prehospital and hospital-based emergency care. In the Netherlands, a new model for Mass Casualty and Disaster Management (MCDM) along with a Terror Attack Mitigation Approach (TAMA) was introduced in 2016.

The objective of this study was to provide insight in the first experiences of health policy advisors and managers with a medical rescue coordinator and ambulance nursing background regarding the new MCDM and TAMA in order to identify strengths and pitfalls in emergency preparedness and to provide recommendations for improvement.

The study had a qualitative design and was performed from January 2017 through June 2018. Purposeful sampling was used and the inclusion comprehended health policy advisors and managers with a medical rescue coordinator and ambulance nursing background involved in emergency preparedness. The respondents were interviewed semi-structured and the researchers used a topic list that was based on the literature and content of the newly introduced model and approach. All interviews were typed out verbatim and qualitative content analyzing was used in order to identify relevant themes.

Respondents based their perceptions on large-scale training exercises, as MCDM and TAMA were not yet used during MCIs. Perceived issues of MCDM were the two-tiered triage system, the change in focus from “stay and play” towards “scoop and run,” difficulties with new tasks and roles of professionals, and improvement in material provision. Regarding TAMA, all respondents supported the principles (do the most for the most; scoop and run; acceptable personal risk; never walk alone; and standard operational procedure); however, the definitions were lacking clarity while the awareness of optimal personal safety of professionals was absent.

As there are currently regional differences in the level of implementation of MCDM and TAMA, this may pose a risk for an optimal inter-regional collaboration.

The conclusions refer to experiences of professionals in the Netherlands. Elements of the MCDM and TAMA were highly appreciated and seemed to improve emergency preparedness, while other aspects needed further attention, training, and integration in daily routine. The Netherlands’ MCDM model and TAMA will need continuous systematic evaluation based on (inter)national performance criteria in order to underpin the useful and effective elements and to improve the observed pitfalls in emergency preparedness.
