Mass-casualty incidents (MCIs) place extraordinary demands on prehospital medical response. However, there remains limited evidence on best practices in managing MCIs, and therefore, there is a need to systematically synthetize experiences from them to build further evidence.

This study aimed to analyze common challenges in prehospital MCI management.

Seventeen case studies or reports describing 15 MCIs (ie, terrorist attacks, chemical incidents, traffic accidents, weather-related incidents, and fires) were subject to a systematic integrative review.

Common challenges in prehospital MCI management include victim and responder safety- and security-related issues; the need to develop and communicate situational awareness; to develop and apply a prehospital response plan; the ability to deliver care under severe circumstances; and the need for an extended prehospital medical response management strategy.

Resilient prehospital MCI response demands both a clear strategy and improvisation and should be integrated into the overall medical response strategy. Responders must understand the main concepts of prehospital MCI management, have a situational awareness that foresees the event’s medical consequences, and have the experience required to interpret the situation. Emergency Medical Services (EMS) personnel and medical incident commanders require specific training and mental preparation to be able to provide care under severe security threats, to improvise beyond routines and guidelines, and to provide care in ways different from their everyday work.

Not all scientific publications are equally useful to policy-makers tasked with mitigating the spread and impact of diseases, especially at the start of novel epidemics and pandemics. The urgent need for actionable, evidence-based information is paramount, but the nature of preprint and peer-reviewed articles published during these times is often at odds with such goals. For example, a lack of novel results and a focus on opinions rather than evidence were common in coronavirus disease (COVID-19) publications at the start of the pandemic in 2019. In this work, we seek to automatically judge the utility of these scientific articles, from a public health policy making persepctive, using only their titles.

Deep learning natural language processing (NLP) models were trained on scientific COVID-19 publication titles from the CORD-19 dataset and evaluated against expert-curated COVID-19 evidence to measure their real-world feasibility at screening these scientific publications in an automated manner.

This work demonstrates that it is possible to judge the utility of COVID-19 scientific articles, from a public health policy-making perspective, based on their title alone, using deep natural language processing (NLP) models.

NLP models can be successfully trained on scienticic articles and used by public health experts to triage and filter the hundreds of new daily publications on novel diseases such as COVID-19 at the start of pandemics.

Events, specifically those where excessive alcohol consumption is common, pose a risk to increase alcohol-related presentations to emergency departments (EDs). Limited evidence exists that synthesizes the impact from events on alcohol-related presentations to EDs.

This integrative review aimed to synthesize the literature regarding the impact events have on alcohol-related presentations to EDs.

An integrative literature review methodology was guided by the Preferred Reporting Items of Systematic Reviews and Meta-Analysis (PRISMA) Guidelines for data collection, and Whittemore and Knafl’s framework for data analysis. Information sources used to identify studies were MEDLINE, CINAHL, and EMBASE, last searched May 26, 2021.

In total, 23 articles describing 46 events met criteria for inclusion. There was a noted increase in alcohol-related presentations to EDs from 27 events, decrease from eight events, and no change from 25 events. Public holidays, music festivals, and sporting events resulted in the majority of increased alcohol-related presentations to EDs. Few articles focused on ED length-of-stay (LOS), treatment, and disposition.

An increase in the consumption of alcohol from holiday, social, and sporting events pose the risk for an influx of presentations to EDs and as a result may negatively impact departmental flow. Further research examining health service outcomes is required that considers the impact of events from a local, national, and global perspective.

Global climate change (global warming) has been identified as the primary factor responsible for the observed increase in frequency and severity of wildfires (also known as bushfires in some countries) throughout the majority of the world’s vegetated environments. This trend is predicted to continue, causing significant adverse health effects to nearby residential populations and placing a potential strain on local emergency departments (EDs).

The aim of this literature review was to identify papers relating to wildfires and their impact on EDs, specifically patient presentation characteristics, resource utilization, and patient outcomes.

This integrative literature review was guided by the Preferred Reporting Items of Systematic Reviews and Meta-Analysis (PRISMA) guidelines for data collection, and Whittemore and Knafl’s framework for data analysis. Data were collected from OvidSP, MEDLINE, DARE, CINAHL, PubMed, and Scopus databases. Various Medical Subject Headings (MeSH) and keywords identified papers relevant to wildfires/bushfires and EDs.

Literature regarding the relationship between ED presentations and wildfire events, however, is primarily limited to studies from the United States and Australia and indicates particulate matter (PM) is principally linked to adverse respiratory and cardiovascular outcomes. Observable trends in the literature principally included a significant increase in respiratory presentations, primarily with a lag of one to two days from the initial event. Respiratory and cardiovascular studies that stratified results by age indicated individuals under five, over 65, or those with pre-existing conditions formed the majority of ED presentations.

Key learnings from this review included the need for effective and targeted community advisory programs/procedures, prior to and during wildfire events, as well as pre-event planning, development, and robust resilience strategies for EDs.

Disaster management (DM) is becoming increasingly complex because of technological advancement and the multi-organization and international contexts. Effective interoperability and adequate collaboration in DM have the potential to spare the human life and to control the economic burden. For those reasons, it’s becoming important to find a way for systems and organizations that exploit, at the same time, the technological interoperability and team’s interoperability.

This study aims to provide an overview of the multi-organizational problems and solutions reflecting on achieving interoperability in multi-organizational DM.

The article is structured as a scoping review based on the Joanna Briggs Institute’s (JBI) methodology for scoping reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist was used to report the results. The selected papers were assessed using the Critical Appraisal Skills Program (CASP) checklists to screen their methodological quality.

The scoping review was conducted systematically searching the databases PubMed, Google Scholar, and Web of Science. The search algorithm was developed using the three key concepts “interoperability; multi-organizational; disaster medicine” translated into different possible search and Medical Subject Headings (MeSH) terms. Studies of all research design types were considered.

The included literature is reporting experiences on interoperability and how it has been applied to health care systems and organizations interacting during a disaster event. Twelve articles were included. Specific problems and solutions were identified regarding the technological and personnel interoperability, such as ineffective integration, technical problems, lack of an interoperability language, and data filtering network. The suggested approach might involve a focus on both the technological as well the human and personnel interoperability with the aim to create a culture of interoperability through compatible technological solutions and joint trainings.

This study identified two main approaches during disasters: technology versus personnel interoperability. The suggested approach is to develop a hybrid culture of interoperability through compatible technological solutions combined to joint and multi-disciplinary trainings to achieve the development of a common language.

Further research will need a solution-focused approach on the culture and language of interoperability as thematic gathering training, socio-technical networks, and policies/procedural guidelines.

Portable oxygen concentrators (POCs) are medical devices that use physical means to separate oxygen from the atmosphere to produce concentrated, medical-grade gas. Providing oxygen to low-resources environments, such as austere locations, military combat zones, rural Emergency Medical Services (EMS), and during disasters, becomes expensive and logistically intensive. Recent advances in separation technology have promoted the development of POC systems ruggedized for austere use. This review provides a comprehensive summary of the available data regarding POCs in these challenge environments.

PubMed, Google Scholar, and the Defense Technical Information Center were searched from inception to November 2021. Articles addressing the use of POCs in low-resource settings were selected. Three authors were independently involved in the search, review, and synthesis of the articles. Evidence was graded using Oxford Centre for Evidence-Based Medicine guidelines.

The initial search identified 349 articles, of which 40 articles were included in the review. A total of 724 study subjects were associated with the included articles. There were no Level I systematic reviews or randomized controlled trials.

Generally, POCs are a low-cost, light-weight tool that may fill gaps in austere, military, veterinary, EMS, and disaster medicine. They are cost-effective in low-resource areas, such as rural and high-altitude hospitals in developing nations, despite relatively high capital costs associated with initial equipment purchase. Implementation of POC in low-resource locations is limited primarily on access to electricity but can otherwise operate for thousands of hours without maintenance. They provide a unique advantage in combat operations as there is no risk of explosive if oxygen tanks are struck by high-velocity projectiles. Despite their deployment throughout the battlespace, there were no manuscripts identified during the review involving the efficacy of POCs for combat casualties or clinical outcomes in combat. Veterinary medicine and animal studies have provided the most robust data on the physiological effectiveness of POCs. The success of POCs during the coronavirus disease 2019 (COVID-19) pandemic highlights the potential for POCs during future mass-casualty events. There is emerging technology available that combines a larger oxygen concentrator with a compressor system capable of refilling small oxygen cylinders, which could transform the delivery of oxygen in austere environments if ruggedized and miniaturized. Future clinical research is needed to quantify the clinical efficacy of POCs in low-resource settings.

Mass-gathering events (MGEs) occur regularly throughout the world. As people congregate at MGEs, there is an increased risk of transmission of communicable diseases. Novel respiratory viruses, such as Severe Acute Respiratory Syndrome Coronavirus-1 (SARS-CoV-1), Influenza A Virus Subtype H1N1 Strain 2009 (H1N1pdm09), Middle East Respiratory Syndrome Coronavirus (MERS-CoV), and Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), or Coronavirus Disease 2019 (COVID-19), may require specific infection prevention and control strategies to minimize the risk of transmission when planning MGEs. This literature review aimed to identify and analyze papers relating to novel respiratory viruses with pandemic potential and to inform MGE planning.

This paper used a systematic literature review method. Various health care databases were searched using keywords relating to MGEs and novel respiratory viruses. Information was extracted from identified papers into various tables for analysis. The analysis identified infection prevention and control strategies used at MGEs to inform planning before, during, and following events.

In total, 27 papers met the criteria for inclusion. No papers were identified regarding SARS-CoV-1, while the remainder reported on H1N1pdm09 (n = 9), MERS-CoV (n = 15), and SARS-CoV-2 (n = 3). Various before, during, and after event mitigation strategies were identified that can be implemented for future events.

This literature review provided an overview of the novel respiratory virus epidemiology at MGEs alongside related public health mitigation strategies that have been implemented at these events. This paper also discusses the health security of event participants and host communities in the context of cancelling, postponing, and modifying events due to a novel respiratory virus. In particular, ways to recommence events incorporating various mitigation strategies are outlined.

Drug and alcohol consumption at sporting mass-gathering events (MGEs) has become part of the spectator culture in some countries. The direct and indirect effects of drug and alcohol intoxication at such MGEs has proven problematic to in-event health services as well as local emergency departments (EDs). With EDs already under significant strain from increasing patient presentations, resulting in access block, it is important to understand the impact of sporting and other MGEs on local health services to better inform future planning and provision of health care delivery.

The aim of this review was to explore the impact of sporting MGEs on local health services with a particular focus on drug and alcohol related presentations.

A well-established integrative literature review methodology was undertaken. Six electronic databases and the Prehospital and Disaster Medicine (PDM) journal were searched to identify primary articles related to the aim of the review. Articles were included if published in English, from January 2008 through July 2019, and focused on a sporting MGE, mass-gathering health, EDs, as well as drug and alcohol related presentations.

Seven papers met the criteria for inclusion with eight individual sporting MGEs reported. The patient presentation rate (PPR) to in-event health services ranged from 0.18/1,000 at a rugby game to 41.9/1,000 at a recreational bicycle ride. The transport to hospital rate (TTHR) ranged from 0.02/1,000 to 19/1,000 at the same events. Drug and alcohol related presentations from sporting MGEs contributed up to 10% of ED presentations. Alcohol was a contributing factor in up to 25% of cases of ambulance transfers.

Drug and alcohol intoxication has varying levels of impact on PPR, TTHR, and ED presentation numbers depending on the type of sporting MGE. More research is needed to understand if drug and alcohol intoxication alone influences PPR, TTHR, and ED presentations or if it is multifactorial. Inconsistent data collection and reporting methods make it challenging to compare different sporting MGEs and propose generalizations. It is imperative that future studies adopt more consistent methods and report drug and alcohol data to better inform resource allocation and care provision.

This review discusses the need for consistency in mass-gathering research and evaluation from a psychosocial perspective.

Mass gatherings occur frequently throughout the world. Having an understanding of the complexities of mass gatherings is important to determine required health resources. Factors within the environmental, psychosocial, and biomedical domains influence the usage of health services at mass gatherings. A standardized approach to data collection is important to identify a consistent reporting standard for the psychosocial domain.

This research used an integrative literature review design. Manuscripts were collected using keyword searches from databases and journal content pages from 2003 through 2018. Data were analyzed and categorized using the existing minimum data set as a framework.

In total, 31 manuscripts met the inclusion criteria. The main variables identified were use of alcohol or drugs, crowd behavior, crowd mood, rationale, and length of stay.

Upon interrogating the literature, the authors have determined that the variables fall under the categories of alcohol or drugs; maladaptive and adaptive behaviors; crowd behavior, crowd culture, and crowd mood; reason for attending event (motivation); duration; and crowd demographics. In collecting psychosocial data from mass gatherings, an agreed-upon set of variables that can be used to collect de-identified psychosocial variables for the purpose of making comparisons across societies for mass-gathering events (MGEs) would be invaluable to researchers and event clinicians.

Spinal cord injury (SCI) is a serious condition that may lead to long-term disabilities placing financial and social burden on patients and their families, as well as their communities. Spinal immobilization has been considered the standard prehospital care for suspected SCI patients. However, there is a lack of consensus on its beneficial impact on patients’ outcome.

This paper reviews the current literature on the epidemiology of traumatic SCI and the practice of prehospital spinal immobilization.

A search of literature was undertaken utilizing the online databases Ovid Medline, PubMed, CINAHL, and the Cochrane Library. The search included English language publications from January 2000 through November 2012.

The reported annual incidence of SCI ranges from 12.7 to 52.2 per 1 million and occurs more commonly among males than females. Motor vehicle collisions (MVCs) are the major reported causes of traumatic SCI among young and middle-aged patients, and falls are the major reported causes among patients older than 55. There is little evidence regarding the relationship between prehospital spinal immobilization and patient neurological outcomes. However, early patient transfer (8-24 hours) to spinal care units and effective resuscitation have been demonstrated to lead to better neurological outcomes.

This review reaffirms the need for further research to validate the advantages, disadvantages, and the effects of spinal immobilization on patients’ neurological outcomes.
