Synchronized cardioversion is an internationally accepted standard therapy for unstable tachyarrhythmias, but it is conventionally an in-hospital physician-led intervention. Increasingly, it is being brought forward into the prehospital setting as part of a specialist paramedic scope of practice; however, very little literature exists regarding the epidemiology or efficacy in this setting.

All patients receiving cardioversion within a United Kingdom (UK) ambulance service were identified using an electronic database. The period of inclusion was March 1, 2017 through October 31, 2020. These data were then interrogated to provide demographic, physiological, and efficacy data, and then a sub-group was created to identify those who presented with a primary arrhythmia (as opposed to post-cardiac arrest).

From a total of 93 patients, prehospital synchronized cardioversion successfully terminated the tachyarrhythmia in 96% of patients presenting with a primary arrhythmia (85% in the allcomers group) with a predominance towards males (82% of patients) and an average age of 67 years. Hypotension and reduced level of consciousness were the most commonly documented unstable features (84.4% and 44.4%).

Cardioversion within a paramedic-led service results in efficacy rates of 96% in patients presenting with a primary tachyarrhythmia. This is a similar efficacy rate to traditional doctor-led therapies. Demographic data show that males make up over 80% of the patient population, in keeping with previously published work across the spectrum of cardiac interventions.

The majority of injury deaths occur outside health facilities. However, many low- and middle-income countries (LMICs) continue to lack efficient Emergency Medical Services (EMS). Understanding current first aid practices and perceptions among members of the community is vital to strengthening non-EMS, community-based prehospital care.

This study sought to determine caregiver first aid practices and care-seeking behavior for common household child injuries in rural communities in Ghana to inform context-specific interventions to improve prehospital care in LMICs.

A cluster-randomized, population-based household survey of caregivers of children under five years in a rural sub-district (Amakom) in Ghana was conducted. Caregivers were asked about their practices and care-seeking behaviors should children sustain injuries at home. Common injuries of interest were burns, laceration, choking, and fractures. Multiple responses were permitted and reported practices were categorized as: recommended, low-risk, or potentially harmful to the child. Logistic regression was used to examine the association between caregiver characteristics and first aid practices.

Three hundred and fifty-seven individuals were sampled, representing 5,634 caregivers in Amakom. Mean age was 33 years. Most (79%) were mothers to the children; 68% had only completed basic education. Most caregivers (64%-99%) would employ recommended first aid practices to manage common injuries, such as running cool water over a burn injury or tying a bleeding laceration with a piece of cloth. Nonetheless, seven percent to 56% would also employ practices which were potentially harmful to the child, such as attempting manual removal of a choking object or treating fractures at home without taking the child to a health facility. Reporting only recommended practices ranged from zero percent (burns) to 93% (choking). Reporting only potentially harmful practices ranged from zero percent (burns) to 20% (fractures). Univariate regression analysis did not reveal consistent associations between various caregiver characteristics and the employment of recommended only or potentially harmful only first aid practices.

Caregivers in rural Ghanaian communities reported using some recommended first aid practices for common household injuries in children. However, they also employed many potentially harmful practices. This study highlights the need to increase context-appropriate, community-targeted first aid training programs for rural community populations of LMICs. This is important as the home-based care provided for injured children in these communities might be the only care they receive.

Anaphylactic reactions can lead to a life-threatening situation. In the event of anaphylaxis, rapid and targeted emergency treatment is indicated.

The study sought to determine the emergency therapy administered for anaphylaxis in children and adults. Focus was placed on therapy with adrenaline. In addition, the study aimed to investigate demographic data, triggers, and hospitalization rates of the different severities of anaphylaxis.

A retrospective analysis of anaphylactic reactions was conducted using data from prehospital emergency missions performed by the Air Rescue Dresden/Germany from 2008 through 2015 using the standardized application protocol EPRO-5.0 (MIND 3) anonymized. Data from 152 adults and 29 children were evaluated, focusing especially on the acute treatment as well as demographic information, triggers, and symptoms of anaphylactic reactions.

In total, 152 adults (73 female, 79 male) from 18 to 87 years (mean 50.5 years) and 29 children (9 female, 20 male) from 1 to 16 years (mean 7.5 years) with anaphylactic reactions were analyzed. The most common trigger for severe anaphylactic reactions (Grade II-IV; classification modified according to Ring and Messmer) was food in children (33%) and insect venom in adults (59%). The data show that 19% of adults with Grade II-IV anaphylactic reactions (classification modified according to Ring and Messmer) received adrenaline. Regarding children, the appliance of adrenaline was only administered in seven percent of the cases of Grade II-IV anaphylactic reactions. Adults with Grade II or higher anaphylactic reactions were hospitalized in 92%. Three percent refused hospitalization and five percent were not transferred to hospital. One-hundred percent of the children with Grade II-IV anaphylaxis were hospitalized.

Analysis of data from the Air Rescue Dresden/Germany shows that despite existing recommendations, only 19% of adults with severe anaphylaxis received adrenaline. Among children, only in seven percent was a treatment with adrenaline performed.

On the other hand, all patients survived the acute emergency treatment without apparent adverse outcomes. Thus, further studies are needed to determine the proper use of adrenaline in anaphylactic reactions.

Gender disparities between Emergency Medicine physicians with regards to salary, promotion, and scholarly recognition as national conference speakers have been well-documented. However, little is known if similar gender disparities impact their out-of-hospital Emergency Medical Services (EMS) colleagues. Although there have been improvements in the ratio of women entering the EMS workforce, gender representation has improved at a slower rate for paramedics compared to emergency medical technicians (EMTs). Since recruitment, retention, and advancement of females within a specialty have been associated with the visibility of prominent, respected female leaders, gender disparity of these leaders as national conference speakers may contribute to the “leaky pipeline effect” seen within the EMS profession. Gender representation of these speakers has yet to be described objectively.

The primary objective of this study was to determine if disparity exists in gender representation of speakers at well-known national EMS conferences and trade shows in the United States (US) from 2016-2020. The secondary objective was to determine if males were more likely than females to return to a conference as a speaker in subsequent years.

A cross-sectional analysis of programs from well-known national conferences, specifically for EMS providers, which were held in the US from 2016-2020 was performed. Programs were abstracted for type of conference session (pre-conference, keynote, main conference) and speakers’ names. Speaker gender (male, female) was confirmed via internet search.

Seventeen conference programs were obtained with 1,709 conference sessions that had a total of 2,731 listed speaker names, of whom 537 (20%) were female. A total of 30 keynote addresses had 39 listed speaker names of whom six (15%) were female. No significant difference was observed in the number of years males returned to present at the same conference as compared to females.

Gender representation of speakers at national EMS conferences in the US is not reflective of the current best estimate of the US EMS workforce. This disparity exists not only in the overall percent of female names listed as speakers, but also in the percent of individual female speakers, and is most pronounced within keynote speakers. Online lecture platforms, as an unintentional consequent of the COVID-19 pandemic, coupled with intentional speaker development and mentorship initiatives, may reduce barriers to facilitating a new pipeline for more females to become speakers at national EMS conferences.

The pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), or coronavirus disease 2019 (COVID-19), has affected many people in the world and has impacted the physical, social, and mental health of the world population. One of these psychological consequences is intimate partner violence affecting sexual health.

This study was performed as a systematic review on the effect of the SARS-CoV-2 pandemic on sexual function and domestic violence in the world. Accordingly, all English-language studies conducted from the beginning of the SARS-CoV-2 pandemic to the end of 2020 were extracted by searching in the Scopus, Web of Science, PubMed (including Medline), Cochrane Library, and Science Direct databases and then reviewed. The quality of the articles was assessed using the STROBE checklist.

A total of 11 studies were included in the systematic review. Accordingly, domestic violence during the exposure to COVID-19 had increased. Moreover, the mean scores of sexual function and its components had reduced at the time of exposure to the pandemic compared to before.

Given the potential long-term effects of the coronavirus crisis and the large population being affected by this disease, strategies to promote sexual health and fertility of families to prevent or further reduce violence and sexual functions should be chosen.

Without a robust evidence base to support recommendations for first aid, health, and medical services at mass gatherings (MGs), levels of care will continue to vary. Streamlining and standardizing post-event reporting for MG medical services could improve inter-event comparability, and prospectively influence event safety and planning through the application of a research template, thereby supporting and promoting growth of the evidence base and the operational safety of this discipline. Understanding the relationships between categories of variables is key. The present paper is focused on theory building, providing an evolving conceptual model, laying the groundwork for exploring the relationships between categories of variables pertaining the health outcomes of MGs.

A content analysis of 54 published post-event medical case reports, including a comparison of the features of published data models for MG health outcomes.

A layered model of essential conceptual components for post-event medical reporting is presented as the Data Reporting, Evaluation, & Analysis for Mass-Gathering Medicine (DREAM) model. This model is relational and embeds data domains, organized operationally, into “inputs,” “modifiers,” “actuals,” and “outputs” and organized temporally into pre-, during, post-event, and reporting phases.

Situating the DREAM model in relation to existing models for data collection vis a vis health outcomes, the authors provide a detailed discussion on similarities and points of difference.

Currently, data collection and analysis related to understanding health outcomes arising from MGs is not informed by robust conceptual models. This paper is part of a series of nested papers focused on the future state of post-event medical reporting.

Terrorist attacks and civilian mass-casualty events are frequent, and some countries have implemented tourniquet use for uncontrollable extremity bleeding in civilian settings. The aim of this study was to summarize current knowledge on the use of prehospital tourniquets to assess whether their use increases the survival rate in civilian patients with life-threatening hemorrhages from the extremities.

Systematic literature review in Medline (Ovid), Embase (Ovid), Cochrane Library, and Epistemonikos was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. The search was performed in January 2019.

All types of studies that examined use of tourniquets in a prehospital setting published after January 1, 2000 were included.

The primary outcome was mortality with and without tourniquet, while adverse effects of tourniquet use were secondary outcomes.

Among 3,460 screened records, 55 studies were identified as relevant. The studies were highly heterogeneous with low quality of evidence. Most studies reported increased survival in the tourniquet group, but few had relevant comparators, and the survival benefit was difficult to estimate. Most studies reported a reduced need for blood transfusion, with few and mainly transient adverse effects from tourniquet use.

Despite relatively low evidence, the studies consistently suggested that the use of commercial tourniquets in a civilian setting to control life-threatening extremity hemorrhage seemed to be associated with improved survival, reduced need for blood transfusion, and few and transient adverse effects.

Massive hemorrhage (MH) is a growing pathology in military settings and increasingly in civilian settings; it is now considered a public health problem in the United States with large-scale programs. Tourniquets are the fastest and most effective intervention in MH if direct pressure is not effective.

The Liaison Committee on Resuscitation (ILCOR) recognizes a knowledge gap in optimal education techniques for first aid providers. This review aims to describe training and evaluation methods for teaching tourniquet use to both health care and military professionals.

The MEDLINE, CINAHL, WEB of Science, and Scopus databases were reviewed (from 2010 through April 2020). The quality of the selected studies was assessed using the Consolidated Standards of Reporting Trials (CONSORT) scale. Studies that met at least 65% of the included items were included. Data were extracted independently by two reviewers.

Ten of the 172 articles found were selected, of which three were randomized clinical trials. Heterogeneity was observed in the design of the studies and in the training and evaluative methods that limit the comparison between studies.

The results suggest that the training strategies studied are effective in improving knowledge, attitudes, and practical skills. There is no universal method, learning is meaningful but research should be directed to find out which ones work best.

The proliferation of unmanned aerial vehicle (UAV) technology has the potential to change the situational awareness of medical incident commanders’ (ICs’) scene assessment of mass gatherings. Mass gatherings occur frequently and the potential for injury at these events is considered higher than the general population. These events have generated mass-casualty incidents (MCIs) in the past. The aim of this study was to compare UAV technology to standard practice (SP) in scene assessment using paramedic students during a mass-gathering event (MGE).

This study was conducted in two phases. Phase One consisted of validation of the videos and accompanying data collection tool. Phase One was completed by 11 experienced paramedics from a provincial Emergency Medical Services (EMS) service. Phase Two was a randomized comparison with 47 paramedic students from the Holland College Paramedicine Program (Charlottetown, Prince Edward Island, Canada) of the two scene assessment systems. For Phase Two, the paramedic students were randomized into a UAV or a SP group. The data collection tool consisted of two board categories: primary importance with 20 variables and secondary importance with 25 variables. After a brief narrative, participants were either shown UAV footage or the ground footage depending on their study group. After completion of the videos, study participants completed the data collection tool.

The Phase One validation showed good consensus in answers to most questions (average 79%; range 55%-100%). For Phase Two, a Fisher’s exact test was used to compare each variable from the UAV and SP groups using a P value of .05. Phase Two demonstrated a significant difference between the SP and UAV groups in four of 20 primary variables. Additionally, significant differences were found for seven out of 25 secondary variables.

This study demonstrated the accurate, safe, and feasible use of a UAV as a tool for scene assessment by paramedic students at an MGE. No observed statistical difference was noted in a majority of both primary and secondary variables using a UAV for scene assessment versus SP.

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.

Pneumothorax remains an important cause of preventable trauma death. The aim of this systematic review is to synthesize the recent evidence on the efficacy, patient outcomes, and adverse events of different chest decompression approaches relevant to the out-of-hospital setting.

A comprehensive literature search was performed using five databases (from January 1, 2014 through June 15, 2020). To be considered eligible, studies required to report original data on decompression of suspected or proven traumatic pneumothorax and be considered relevant to the prehospital context. They also required to be conducted mostly on an adult population (expected more than ≥80% of the population ≥16 years old) of patients. Needle chest decompression (NCD), finger thoracostomy (FT), and tube thoracostomy were considered. No meta-analysis was performed. Level of evidence was assigned using the Harbour and Miller system.

A total of 1,420 citations were obtained by the search strategy, of which 20 studies were included. Overall, the level of evidence was low. Eleven studies reported on the efficacy and patient outcomes following chest decompression. The most studied technique was NCD (n = 7), followed by FT (n = 5). Definitions of a successful chest decompression were heterogeneous. Subjective improvement following NCD ranged between 18% and 86% (n = 6). Successful FT was reported for between 9.7% and 32.0% of interventions following a traumatic cardiac arrest. Adverse events were infrequently reported. Nine studies presented only on anatomical measures with predicted failure and success. The mean anterior chest wall thickness (CWT) was larger than the lateral CWT in all studies except one. The predicted success rate of NCD ranged between 90% and 100% when using needle >7cm (n = 7) both for the lateral and anterior approaches. The reported risk of iatrogenic injuries was higher for the lateral approach, mostly on the left side because of the proximity with the heart.

Based on observational studies with a low level of evidence, prehospital NCD should be performed using a needle >7cm length with either a lateral or anterior approach. While FT is an interesting diagnostic and therapeutic approach, evidence on the success rates and complications is limited. High-quality studies are required to determine the optimal chest decompression approach applicable in the out-of-hospital setting.

In a disaster aftermath, pharmacists have the potential to provide essential health services and contribute to the maintenance of the health and well-being of their community. Despite their importance in the health care system, little is known about the factors that affect pharmacists’ disaster preparedness and associated behaviors.

The goal of this study was to determine the factors that influence disaster preparedness behaviors and disaster preparedness of Australian pharmacists.

A 70-question survey was developed from previous research findings. This survey was released online and registered Australian pharmacists were invited to participate. Multiple linear regression was used to determine the factors that influenced preparedness and preparedness behaviors among pharmacists.

The final model of disaster preparedness indicated that 86.0% of variation in preparedness was explained by disaster experience, perceived knowledge and skills, colleague preparedness, perceived self-efficacy, previous preparedness behaviors, perceived potential disaster severity, and trust of external information sources. The final model of preparedness behaviors indicated that 71.1% of variation in previous preparedness behaviors can be explained by disaster experience, perceived institution responsibility, colleague preparedness, perceived likelihood of disaster, perceived professional responsibility, and years of practice as a pharmacist.

This research is the first to explore the significant factors affecting preparedness behaviors and preparedness of Australian pharmacists for disasters. It begins to provide insight into potential critical gaps in current disaster preparedness behaviors and preparedness among pharmacists.

In the absence of evidence of acute cerebral herniation, normal ventilation is recommended for patients with traumatic brain injury (TBI). Despite this recommendation, ventilation strategies vary during the initial management of patients with TBI and may impact outcome. The goal of this systematic review was to define the best evidence-based practice of ventilation management during the initial resuscitation period.

A literature search of PubMed, CINAHL, and SCOPUS identified studies from 2009 through 2019 addressing the effects of ventilation during the initial post-trauma resuscitation on patient outcomes.

The initial search yielded 899 articles, from which 13 were relevant and selected for full-text review. Six of the 13 articles met the inclusion criteria, all of which reported on patients with TBI. Either end-tidal carbon dioxide (ETCO2) or partial pressure carbon dioxide (PCO2) were the independent variables associated with mortality. Decreased rates of mortality were reported in patients with normal PCO2 or ETCO2.

Normoventilation, as measured by ETCO2 or PCO2, is associated with decreased mortality in patients with TBI. Preventing hyperventilation or hypoventilation in patients with TBI during the early resuscitation phase could improve outcome after TBI.
