Chemical, biological, radiological, and nuclear (CBRN) events with multiple casualties are rare events, but preparedness is crucial for hospitals to respond properly. This study evaluated the preparedness and disaster planning of German hospitals for CBRN incidents.

In a cross-sectional study, German hospitals with level III (highest level) emergency departments were surveyed using an online questionnaire focusing on risk assessment, infrastructure, hospital disaster planning, and preparedness for CBRN events.

Between June and July 2023, 50 hospitals were surveyed. 62.5% of the hospitals had a section on chemical incidents in their disaster plan. A decontamination facility was available in 29.8% of the hospitals and chemical protective suits in 46.8%. The minority of the hospitals trained the correct handling of personal protective equipment (PPE) (39.1%) regularly or had frequent CBRN drills (21.3%). Most hospitals had the infrastructure for medical isolation (93.6%).

The level of CBRN preparedness is heterogeneous for German hospitals. Most were well prepared for infectious patients, but only half of all hospitals had sufficient PPE for chemical incidents and only 30% had a decontamination facility available. Overall, the level of CBRN preparedness is still insufficient and needs further improvement.

Mass Casualty Incidents (MCIs) involving high-speed passenger ferries (HSPFs) may result in the dual-wave phenomenon, in which the emergency department (ED) is overwhelmed by an initial wave of minor injuries, followed by a second wave of more seriously injured victims. This study aimed to characterize the time pattern of ED presentation of victims in such accidents in Hong Kong.

All HSPF MCIs from 2005 to 2015 were reviewed retrospectively, with the time interval from accident to ED registration determined for each victim. Multivariable linear regression was used to identify independent factors associated with the time of ED presentation after the accidents.

Eight MCIs involving 492 victims were identified. Victims with an Injury Severity Score (ISS) ≥ 9 had a significantly shorter median time interval compared to those with minor injuries. An ISS ≥ 9 and evacuation by emergency service vessels were associated with a shorter delay in ED arrival, whereas ship sinking, accident at nighttime, and a longer linear distance between the accident and receiving ED were associated with a longer delay.

The dual-wave phenomenon was not present in HSPF MCIs. Early communication is the key to ensure early resource mobilisation and a well-timed response.

As disasters are rare and high-impact events, it is important that the learnings from disasters are maximized. The aim of this study was to explore the effect of exposure to a past disaster or mass casualty incident (MCI) on local hospital surge capacity planning.

The current hospital preparedness plans of hospitals receiving surgical emergency patients in Finland were collected (n = 28) and analyzed using the World Health Organization (WHO) hospital emergency checklist tool. The surge capacity score was compared between the hospitals that had been exposed to a disaster or MCI with those who had not.

The overall median score of all key components on the WHO checklist was 76% (range 24%). The median surge capacity score was 65% (range 39%). There was no statistical difference between the surge capacity score of the hospitals with history of a disaster or MCI compared to those without (65% for both, P = 0.735).

Exposure to a past disaster or MCI did not appear to be associated with an increased local hospital disaster surge capacity score. The study suggests that disaster planning should include structured post-action processes for enabling meaningful improvement after an experienced disaster or MCI.

The purpose of this study was to explore the experiences of nurses who responded to a public mass shooting in 2017.

This qualitative study was conducted with a sample of nurses who responded to a mass shooting, recruited purposively from a hospital in Las Vegas, Nevada. Intensive interviews were conducted with a total of 7 nurses, audio-recorded and transcribed for thematic analysis.

Six themes were developed from interview data: (1) “The worst night of my life”: Overrun and overwhelmed; (2) Unexpected altruism and benevolence of patients and staff; (3) “The Wild West”: Giving victim care by improvising beyond rules; (4) Experiencing a range of reactions in the immediate aftermath and in the long term; (5) Shifts in nursing practice and evolving team dynamics; and (6) Defining realistic approaches to support staff mental health and mass casualty preparation.

Nurses who were involved in responding to the public mass shooting described the event as life-altering. Given the critical role of nurses in responding to mass shootings, it is essential to consider how nurses can be supported in the aftermath of these events and how mass disaster preparation can include attention to the needs of nurses.

The Western Regional Alliance for Pediatric Emergency Medicine (WRAP-EM) is a multi-state, Administration for Strategic Preparedness and Response (ASPR) funded pediatric disaster center of excellence. WRAP-EM set out to determine the impact of health disparities on its 11 core areas.

We conducted 11 focus groups during April 2021. Discussions were led by an experienced facilitator, and participants could also include their thoughts on a Padlet throughout the discussion. Data were analyzed to determine overarching themes.

Responses focused on health literacy, health disparities, resource opportunities, addressing obstacles, and resilience building. Health literacy data highlighted the need for development of readiness and preparedness plans, community engagement in cultural and language appropriate means, and increasing diversity in training. Obstacles faced included funding; inequitable distribution of research, resources, and supplies; lack of prioritization of pediatric needs; and fear of retribution from the system. Multiple already existing resources and programs were referenced highlighting the importance of best practice sharing and networking. A stronger commitment to mental health-care delivery, empowerment of individuals and communities, use of telemedicine, and ongoing cultural and diverse education were recurring themes.

Results of the focus groups can be used to prioritize efforts to address and improve health disparities in pediatric disaster preparedness.

For the pediatric population, there is no consensus on which triage system to use for mass-casualty incidents (MCI). A scoping review was conducted to identify the most accurate triage system for pediatric patients in MCIs.

MEDLINE (NLM, Bethesda, MA, USA), Embase (Elsevier Inc., Amsterdam, Netherlands), CINAHL (EBSCO Information Services, Ipswitch, MA, USA), and The Cochrane CENTRAL Register of Controlled Trials (John Wiley & Sons, Hoboken, NJ, USA), as well as Scopus (Elsevier Inc., Amsterdam, Netherlands), Global Health (Centre for Agriculture and Bioscience International, Wallingford, UK), Global Health Archive (Centre for Agriculture and Bioscience International, Wallingford, UK), and Global Index Medicus (World Health Organization, Geneva, Switzerland) were searched for relevant studies that were divided into 3 categories: accuracy of a single system, comparison of 2 or more primary triage system and comparison of secondary triage systems. Grey literature was also searched.

996 studies were identified from which 18 studies were included. Systems studied were found to have poor inter-rater reliability, had a low level of agreement between providers, had missed critically ill patients or were not externally validated. 11 studies compared pediatric MCI triage algorithms using different strategies and the most accurate algorithm was not identified. A recently developed secondary triage system, specifically for pediatric patients, was found to perform better than the comparison triage system.

Although some algorithms performed better than others, no primary triage algorithm was accurate enough for the pediatric population. However, only 1 secondary triage algorithm was found to be superior to the others.

Emergency medical (EM) response systems require extensive coordination, particularly during mass casualty incidents (MCIs). The recognition of preparedness gaps and contextual priorities to MCI response capacity in low- and middle-income countries (LMICs) can be better understood through the components of EM reponse systems. This study aims to delineate essential components and provide a framework for effective emergency medical response to MCIs.

A scoping review was conducted using 4 databases. Title and abstract screening was followed by full-text review. Thematic analysis was conducted to identify themes pertaining to the essential components and integration of EM response systems.

Of 20,456 screened citations, 181 articles were included in the analysis. Seven major and 40 sub-themes emerged from the content analysis as the essential components and supportive elements of MCI medical response. The essential components of MCI response were integrated into a framework demonstrating interrelated connections between essential and supportive elements.

Definitions of essential components of EM response to MCIs vary considerably. Most literature pertaining to MCI response originates from high income countries with far fewer reports from LMICs. Integration of essential components is needed in different geopolitical and economic contexts to ensure an effective MCI emergency medical response.

The study objective was to determine the feasibility of training physicians in the principles of the National Incident Management System (NIMS) and Incident Command System (ICS) as applied to in-hospital rapid responses and to assess physicians’ attitudes regarding rapid responses.

This was an educational pilot study. Resident physicians completed a pre-survey, followed by online training in the principles of NIMS and ICS, a knowledge test, and a post-survey.

The number of residents who participated was 22. In the pre-survey, most (20/22) did not have a working understanding of NIMS/ICS. Participants (21/22) agreed that residents should have more training in resource organization. On the knowledge test, the median score was 9.5/10. In the post-survey, participants felt more comfortable clearing extra resources from the scene (P < 0.001) and that it would be easier to keep track of resources (P < 0.001). Most indicated that they had a working understanding of NIMS/ICS (P < 0.001) and felt more comfortable establishing command using NIMS/ICS (P < 0.001). All agreed that they would consider using an NIMS/ICS-based structure on their next rapid response.

Training physicians in the principles of NIMS/ICS as they pertain to rapid responses is feasible and appears to change residents’ attitudes about rapid responses.

Emergency departments should improve their preparedness for mass casualty incidents (MCIs) through periodic drills. These exercises are conducted while maintaining regular care. The aim of this study was to determine the impact of a disaster drill in a pediatric emergency department (PED) on real patients’ waiting times.

On September 10, 2019, a 4-h disaster drill was conducted in the PED of a tertiary pediatric hospital, with minimal staff reinforcement (2 nurses). Cases were real patients that came to the PED during the drill. The patients that visited the PED the day before were the control group. Variables analyzed were: age, sex, destination, triage level, time-to-triage, time-to-physician, length of PED stay, and percentage of patients visited within the optimal time according to triage level.

Sixty-eight patients (case group) and 63 patients (control group) were analyzed; both groups were comparable except for the median age. There were no differences in time-to-triage, time-to-physician, and length of PED stay between the 2 groups. The percentage of patients visited within optimal time according to triage level was higher in the case group.

Conducting an MCI drill in the PED, with minimal staff reinforcement, was not detrimental to real patients’ waiting times.

We sought to determine who is involved in the care of a trauma patient.

We recorded hospital personnel involved in 24 adult Priority 1 trauma patient admissions for 12 h or until patient demise. Hospital personnel were delineated by professional background and role.

We cataloged 19 males and 5 females with a median age of 50-y-old (interquartile range [IQR], 35.5-67.5). The average number of hospital personnel involved was 79.71 (standard deviation, 17.62; standard error 3.6). A median of 51.2% (IQR, 43.4%-59.8%) of personnel were first involved within hour 1. More personnel were involved in direct versus indirect care (median 54.5 [IQR, 47.5-67.0] vs 25.0 [IQR, 22.0-30.5]; P < 0.0001). Median number of health-care professionals and auxiliary staff were 74.5 (IQR, 63.5-90.5) and 6.0 (IQR, 5.0-7.0), respectively. More personnel were first involved in hospital locations external to the emergency department (median, 53.0 [IQR, 41.5-63.0] vs 27.5 [IQR, 24.0-30.0]; P < 0.0001). No differences existed in total personnel by Injury Severity Score (P = 0.1266), day (P = 0.7270), or time of admission (P = 0.2098).

A large number of hospital personnel with varying job responsibilities respond to severe trauma. These data may guide hospital staffing and disaster preparedness policies.

The aim of this study was to develop a context-bound model of hospital triage in disasters and mass casualty incidents in the health system of Iran.

This study was done using a sequential mixed method. Data were analyzed using Expert Choice software program.

In the qualitative phase, 27 specialists were interviewed. Walking and purposeful movement, airway and respiration, circulatory status, and mental indices were included in the finalized model. In the quantitative phase, 21 participants responded to a questionnaire for weighting and ranking the final indices based on 3 competing options, including clinical importance of the index, lack of complexity and simplicity in implementation, and speed of implementation. The index of walking and purposeful movements weighing 0.300 and ranking 1, airway and respiration weighing 0.276 and ranking 2, blood circulatory status weighing 0.245 and ranking 3, and finally mental status weighing 0.179 and ranking 4 were obtained.

This is the first attempt to design and develop a new context-bound model of hospital triage in disasters and mass casualties in Iran. The development of new triage models is a dynamic and continuous process, and changes will be applied to them, in case further developments and improvements are required.

Coronavirus disease 2019 (COVID-19, caused by severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) is a historic pandemic severely impacting health care. This study examines its early effect on a busy academic emergency department.

A retrospective analysis of patients from an academic tertiary care Level I trauma, cardiac and stroke center’s emergency department seeing an average of 54,000 adults and 21,000 pediatric patients per year. Total visits, reasons for patient visits, demographics, disposition, and length of stay were analyzed from January through July 2020 and compared with the same time period in the previous 2 y.

From March through July 2020 there were statistically significant decreases in the total number of patient visits (-47%) especially among pediatric (-73%) and elderly (-43%) patients and those with cardiovascular (-39%), neurological (-63%) complaints, headaches (-60%), back pain (-64%), abdominal pain (-51%), and minor trauma (-71%). There was, however, a significant increase in pulmonary complaints (+54%), as well as admissions (+32%), and length of stay (+40%).

There was a significant drop in overall patients and select groups early in the pandemic, while admissions and emergency department length of stay both increased. This has implications for future pandemic planning.

Global health disasters are on the rise and can occur at any time with little advance warning, necessitating preparation. The authors created a comprehensive evidence-based Emergency Preparedness Training Program focused on long-term retention and sustained learner engagement.

A prospective observational study was conducted of a simulation-based mass casualty event training program designed using an outcomes-based logic model. A total of 25 frontline healthcare workers from multiple hospital sites in the New York metropolitan area participated in an 8-hour immersive workshop. Data was collected from assessments, and surveys provided to participants 3 weeks prior to the workshop, immediately following the workshop, and 3 months after completion of the workshop.

The mean percentage of total knowledge scores improved across pre-workshop, post-workshop and retention (3 months post-workshop) assessments (53.2% vs. 64.8% vs. 67.6%, P < 0.05). Average comfort scores in the core MCI competencies increased across pre-workshop, post-workshop and retention self-assessments (P < 0.01). Of the participants assessed at 3 months retention (n = 14, 56%), 50.0% (n = 7) assisted in updating their hospital’s emergency operations plan and 50.0% (n = 7) pursued further self-directed learning in disaster preparedness medicine.

The use of the logic model provided a transparent framework for the design, implementation, and evaluation of a competency-based EPT program at a single academic center.

Prehospital time affects survival in trauma patients. Mass casualty incidents (MCIs) are overwhelming events where medical care exceeds available resources. This study aimed at evaluating the prehospital time during MCIs and investigating the effect of triage.

A retrospective analysis was performed using Florida’s Event Medical Services Tracking and Reporting System database. All patients involved in MCIs during 2018 were accessed, and prehospital time intervals were evaluated and compared to that of non-MCIs. The effect of MCI triage and field triage (Field Triage Criteria) on prehospital time was evaluated.

In 2018, it was estimated that 2236 unique MCIs occurred in Florida, with a crude incidence of 10.1-10.9/100000 people. 2180 EMS units arrived at the hospital for patient disposition with a median alarm-to-hospital time of 43.74 minutes, significantly longer than non-MCIs (39.15 min; P < 0.001). MCI triage and field triage were both associated with shorter alarm-to-hospital time (39.37 min and 37.55 min, respectively).

MCIs resulted in longer prehospital time intervals than non-MCIs. This finding suggests that additional efforts are needed to reduce the prehospital time for MCI patients. MCI triage and field triage were both associated with shorter alarm-to-hospital times. Widespread use may improve prehospital MCI care.
