This paper provides a large-scale, per-National Hockey League (NHL) season analysis of hockey puck strike (HPS) injury data and also provides estimates of injury frequency and severity.
Objective:
The study’s goal was to quantify and describe the rate and type of spectator HPS injuries at NHL games.
Design:
This was a retrospective review of summary data reports for patients evaluated by on-site health care providers over six seasons (2013-2018). Data were obtained from a single Emergency Medical Service (EMS) agency.
Setting:
Location of study was one US-based NHL venue.
Results:
There were 51 HPS recorded. This accounted for 0.93% of total patient contacts translating to a patient per 10,000 (PPTT) of 0.116. This was compared to a PPTT of 12.6 for all patient contacts. The average age of a patron with a HPS was 31 years old. There was an even split between male and female patrons with HPS. The most common location for a HPS was the head or face (75%) followed by upper extremity injuries. Laceration was most frequently diagnosed followed by contusions and pain. Approximately one-quarter of people struck by hockey pucks were transported to the hospital, with the transport to hospital rate (TTHR) being 0.027, compared to the total TTHR of 2.7.
Conclusions and Relevance:
Hockey is a safe sport to watch, although HPS are the spectator hazard of concern given that pucks can travel into the stands at 100mph. Most injuries are minor and occur only one percent of the time; but when they do occur, these fans tend to need transport to the hospital. Finally, HPS tend to occur along the lateral sides of the rink where the glass level is lower and there is no protective netting.
Prehospital ultrasounds can be considered a new form of diagnostic tool when taking into account their small structure and due to the fact that nowadays, they are used in the care of emergency patients. However, at present, there is no study regarding the advantage of ultrasound usage in prehospital settings in Thailand.
Study Objective:
This study aims to determine the sonographic characteristics recorded by handheld ultrasounds used in prehospital care and the diagnostic accuracy of ultrasounds for prehospital patients.
Methods:
A cross-sectional study was conducted on prehospital patients who underwent point-of-care ultrasound (POCUS) examination on Emergency Medical Service (EMS) operations at Srinagarind Hospital, Thailand from January 2021 through December 2021. The ultrasound images, the electronic emergency department medical records, and the EMS database were recorded and reviewed by a team of emergency physicians. The quality of prehospital ultrasound examinations was assessed by comparing the diagnoses at the scene with those taken at the hospital.
Results:
One hundred sixty-nine prehospital patients who received POCUS examinations were examined over a one-year period. All (100.0%) of the scans were for medical cases. No ultrasound protocol was used in the prehospital care. Two hundred eight POCUS examinations were performed in this study. The most common POCUS indication was dyspnea (45.6%), followed by hypotension/shock (30.1%), and finally syncope (8.2%). The most common area where POCUS was performed was on the lung (37.0%), followed by the inferior vena cava (30.8%), and finally for cardiac cases (26.4%). This study found that 34.9% of sonographic findings could be considered abnormal. The diagnoses of prehospital patients were confirmed by using POCUS in 66 cases (39.1%) with the accuracy of prehospital diagnosis reaching a peak of 75.8%.
Conclusion:
This study shows POCUS examinations can be effectively used in prehospital care. The prehospital diagnosis given by physicians administering treatment who used POCUS examinations correlated with the in-hospital diagnosis.
The recent United States (US) troop withdrawal out of Afghanistan under a February 2020 US-Taliban agreement and the rapid concurrent collapse of the Afghan military, followed by the ascendance of the Taliban, has placed an international spotlight around the future of South Asian countries. Security threats, in particular, will likely escalate within the region and beyond, with significant concerns around the resurgence of terrorism and violence in the region. This study aims to provide an epidemiological description of all terrorism-related attacks in South Asia sustained from 1970 – 2019. These data will be useful in the development of education programs in Counter-Terrorism Medicine and provide an insight into potential attacks in the future.
Methods:
Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all events which occurred in Afghanistan, Bangladesh, Bhutan, India, Maldives, Mauritius, Nepal, Pakistan, and Sri Lanka (collectively referred to as South Asia) from January 1, 1970 - December 31, 2019. Primary weapon type, primary target type, country where the incident occurred, and number of deaths and injuries were collated and exported for analysis.
Results:
In total, 23.69% of all terrorist attacks from 1970-2019 occurred in the South Asia region, causing 96,092 deaths and 141,333 non-fatal injuries. Of those, 50.1% of attacks in South Asia used explosives, 31.9% used firearms, 9.4% used unknown weapons, 5.9% used incendiary attacks, 2.3% were melee attacks, and <0.5% used chemical, biological, and other weapon types.
Conclusion:
Over 88% of the attacks occurred in Afghanistan, Pakistan, and India combined. While there has been a decline in attacks since a peak in 2014, there are concerns of a significant increase in terrorism activity in recent months which could impact an already fragmented health care system. The use of explosives and firearms as attack modalities accounted for 82.0 % of all weapon types used, but the impact of terrorism and conflict expands beyond simple death and casualty tolls.
Stingray envenomation is a marine injury suffered by ocean goers throughout the world. No prospective studies exist on the various outcomes associated with these injuries.
Study Objective:
The aim of this study was to perform a prospective, observational study of human stingray injuries to determine the natural history, acute and subacute complications, prevalence of medical evaluation, and categories of medical treatment.
Methods:
This study prospectively studied a population of subjects who were injured by stingrays at Seal Beach, California (USA) from July 2012 through September 2016 and did not immediately seek emergency department evaluation. Subjects described their initial injury and provided information on their symptoms, medical evaluations, and medical treatment for the injury at one week and one month after the injury. This information was reported as descriptive statistics.
Results:
A total of 393 participants were enrolled in the study; 313 (80%) of those completed the one-week follow-up interview and 279 (71%) participants completed both the one-week and one-month follow-up interviews. Overall, 234 (75%) injuries occurred to the foot. One hundred sixty-three (52%) patients had complete resolution of their pain within one week and 261 (94%) had either complete resolution or improvement of pain by one month. Sixty-eight (22%) subjects reported being evaluated by a physician and a total of 49 (17%) subjects reported antibiotic treatment for their wound. None of the subjects required parenteral antibiotics or hospital admission.
Conclusion:
The majority of stingray victims recover from stingray injury without requiring antibiotics. A subset of subjects will have on-going wound pain after one month. The need for parenteral antibiotics or hospital admission is rare.
The use of chemical weapons in terrorist attacks, though rare, remains a significant challenge and concern due to their ability to inflict mass casualties. Chemical attacks remain a topic of interest for Disaster Medicine (DM) and Counter-Terrorism Medicine (CTM) specialists and are clearly an area in need of enhanced preparedness. This study aims to provide an epidemiological description of all terrorism-related attacks using chemical agents as a primary weapon, sustained from 1970 - 2019. These data will be useful in the development of education programs in CTM and provide an insight into how best to prepare for potential attacks in the future.
Methods:
Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all events using chemical weapons as a primary attack method from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of the study. The GTD also details the specific chemical used, when known, in the summary of incidents. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.
Results:
A total of 292 terrorist attacks involving chemical agents as a primary attack method were recorded from 1970 - 2019, registering 284 deaths and 13,267 injuries. Acid (52) was the most commonly used chemical agent, followed by “unspecified poison” (43), “unknown chemical agents” (29), “unspecified gas” (27), tear gas (27), chlorine gas (24), cyanide (21), mercury (9), pepper spray or mace (9), mustard gas (8), insecticide or 1080 (8), diphenylamine chloroarsine (7), phosphate or phosphorous (3), sodium hydroxide or corrosive liquid (3), sarin (2), “unspecified drugs” (2), VX nerve gas and other nerve gas (2), pesticides (2), cleaning chemicals/paint thinner (2), ammonia (2), anesthesia agent (1), arsenic (1), chlorine and mustard gas mix (1), phenarsazine chloride (1), rat poison (1), unknown irritative gas (1), hydrochloric acid and sodium cyanide mix (1), unknown white powder (1), antiseptic dye (1), and chlorine gas and white phosphorous mix (1).
Conclusion:
The use of chemical weapons in warfare, though prohibited by the Chemical Weapons Convention (CWC), remains a rare but concerning terrorist attack methodology. In recent years, there have been more instances where potentially deadly chemicals have been used in civilian settings. Dual use industrial chemicals, in particular, pose a significant concern. Acid was the most commonly used chemical weapon in 52 attacks. Tear gas, chlorine, and cyanide were each used in over 20 attacks. Both DM and CTM specialists advocate for better preparedness and response training for intentional events in civilian settings.
Hospitalized neonates are vulnerable to natural and man-made disasters because of their persistent requirement for medical resources and may need to be evacuated to safe locations when electricity and medical gas supply become unreliable. In Japan, a triage system for hospitalized neonates, or the Simple Triage and Rapid Treatment for Neonates, Revised (START-Neo-R), has been used to determine whether neonates are in suitable conditions for transportation. However, this scale is not useful to determine the evacuation order of neonates because a considerable number of evacuees are classified into the same categories.
Study Objective:
To solve this problem, a novel triage system, Neonatal Extrication Triage (NEXT) was developed. This study tested the validity and reproducibility of both triages and compared them with a standardized prognostic scoring system for hospitalized neonates, the Neonatal Therapeutic Intervention Scoring System (NTISS).
Methods:
In this retrospective observational study, physicians and nurses independently assessed each neonate hospitalized at a tertiary neonatal intensive care unit (NICU) twice weekly using NEXT and START-Neo-R. The NEXT system comprises six questionnaires regarding medical resources required during transition and transportation, providing composite scores on a 12-point scale. The START-Neo-R classified neonates into five levels based on the severity of disease and dependence on medical care. Inter-rater reliability of both systems was assessed using Cohen’s kappa coefficient, whereas the criterion validity with NTISS was assessed using Spearman’s correlation coefficient.
Results:
Overall, 162 neonates were assessed for 49 days, resulting in triage data for 1,079 accumulated patients. Both NEXT scores and START-Neo-R ranks were well-dispersed across different levels without excessive accumulation in specific categories. Inter-rater reliability of NEXT (kappa coefficient, 0.973; 95% confidence interval, 0.969-0.976) and START-Neo-R (kappa coefficient, 0.952; 95% confidence interval, 0.946-0.957) between physicians and nurses was sufficiently high. The correlation coefficient of NEXT and START-Neo-R scores with NTISS scores were 0.889 (P <.001) and 0.850 (P <.001), respectively.
Conclusions:
Both START-Neo-R and NEXT had good reproducibility and correlation with the severity of neonates indicated by NTISS. With its well-dispersed scores across different levels, the NEXT system might be a powerful tool to determine the priority of evacuation objectively.
Educational institutions around the world have long been targets of terrorist attacks. Schools, colleges, and universities often lack security measures against intentional threats and may be viewed as relatively easy, soft targets with high potential for mass casualties. The long-term psychosocial impact on children, youth, and survivors of terrorist attacks are significant and recovery remains a challenge. Deliberate attacks on students and children, in particular, can also often gain mass-media attention, provoke significant community unrest, and place a spotlight on the local government’s inability to protect the vulnerable. This study is an epidemiological examination of all terrorism-related events targeting educational institutions from 1970-2019.
Method:
Data collection was performed using a retrospective search through the Global Terrorism Database (GTD). The database was searched using the internal search functions for all events that occurred from January 1, 1970 - December 31, 2019. “Educational institutions” as a primary target type was selected for the purpose of this study and events were further sub-classified by country and attack type. All classifications were pre-determined by the GTD.
Results:
The GTD listed 4,520 attacks against educational institutions, recording 3,732 deaths and 9,920 wounded. This accounted for 2.7% of all terrorist attacks (total 168,003 attacks against all target types). There has been a downtrend in attacks since the 2014 peak when 344 attacks were recorded that year. Pakistan recorded the most attacks with 969 events, followed by Afghanistan (369), India (311), and Iraq (279). The most common attack types included bombing/explosions (2290), facility/infrastructure attacks (636), armed assaults (628), hostage takings (kidnappings [415]), assassinations (357), unarmed assaults (72), unknown (67), hostage takings (barricade incidents [46]), and hijackings (9).
Eight hundred seventy-three of the 4,520 attacks were recorded against teachers, professors, and instructors and 486 attacks were recorded against “other personnel” such as security and non-teaching staff.
Conclusion:
Terrorist attacks on educational institutions are rare but significant target types. In total, 41.2% of attacks on educational institutions occurred in South Asia, followed by 18.9% in the Middle East and North Africa. Western Europe and North America accounted for 3.9% and 3.6%, respectively. Educational institutions around the world should evaluate their risks and put in place appropriate hardening measures as well as preparedness and recovery plans to intentional threats.
The coronavirus disease 2019 (COVID-19) pandemic has challenged the ability of Emergency Medical Services (EMS) providers to maintain personal safety during the treatment and transport of patients potentially infected. Increased rates of COVID-19 infection in EMS providers after patient care exposure, and notably after performing aerosol-generating procedures (AGPs), have been reported. With an already strained workforce seeing rising call volumes and increased risk for AGP-requiring patient presentations, development of novel devices for the protection of EMS providers is of great importance.
Based on the concept of a negative pressure room, the AerosolVE BioDome is designed to encapsulate the patient and contain aerosolized infectious particles produced during AGPs, making the cabin of an EMS vehicle safer for providers. The objective of this study was to determine the efficacy and safety of the tent in mitigating simulated infectious particle spread in varied EMS transport platforms during AGP utilization.
Methods:
Fifteen healthy volunteers were enrolled and distributed amongst three EMS vehicles: a ground ambulance, an aeromedical-configured helicopter, and an aeromedical-configured jet. Sodium chloride particles were used to simulate infectious particles and particle counts were obtained in numerous locations close to the tent and around the patient compartment. Counts near the tent were compared to ambient air with and without use of AGPs (non-rebreather mask, continuous positive airway pressure [CPAP] mask, and high-flow nasal cannula [HFNC]).
Results:
For all transport platforms, with the tent fan off, the particle generator alone, and with all AGPs produced particle counts inside the tent significantly higher than ambient particle counts (P <.0001). With the tent fan powered on, particle counts near the tent, where EMS providers are expected to be located, showed no significant elevation compared to baseline ambient particle counts during the use of the particle generator alone or with use of any of the AGPs across all transport platforms.
Conclusion:
Development of devices to improve safety for EMS providers to allow for use of all available therapies to treat patients while reducing risk of communicable respiratory disease transmission is of paramount importance. The AerosolVE BioDome demonstrated efficacy in creating a negative pressure environment and workspace around the patient and provided significant filtration of simulated respiratory droplets, thus making the confined space of transport vehicles potentially safer for EMS personnel.
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.
Methods:
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.
Discussion:
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.
Conclusions:
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.
Mass-casualty incident (MCI) triage systems aim to provide the best possible health care to the greatest number of affected people with the available resources in the context of a mass-casualty event. The Spanish Prehospital Advanced Triage Method (Modelo Extrahospitalario de Triaje Avanzado; META) was designed to improved patient sorting in MCIs.
Objective:
The aim of this study was to estimate and compare sensitivity and specificity of META and the Manchester Triage System (MTS) in MCIs by retrospectively applying both triage algorithms to real MCI patients from the Emergency and Disaster Research Unit (Unidad de Investigación en Emergencia y Desastres; UIED) MCI database.
Method:
This was a comparative study of two triage methods using sensitivity and specificity with the Revised Trauma Score (RTS) as the gold standard. A total of 134 MCI patients from the UIED database were included. An MCI in Asturias is defined as an incident that involves four or more victims that require ambulance mobilization.
Results:
Patients mean age was 39.85 years (95% CI, 35.9-43.8) with an age range from one to 88 years old. In total, 54.4% of the patients were female. The most common types of MCI involved were fires (51.0%), followed by road traffic accident (43.3%) and street fight (3.7%). For MTS, the overall sensitivity was 30.6% (95% CI, 22.9-39.1) and specificity was 66.0% (95% CI, 60.0-71.7). For META triage algorithm, the overall sensitivity was 79.9% (95% CI, 72.1-86.3) and specificity was 89.9% (95% CI, 85.7-93.3).
Conclusion:
The META triage algorithm is a reliable triage system; thus, it can be recommended to be used in an MCI.
Tropical cyclones are a recurrent, lethal hazard. Climate change, demographic, and development trends contribute to increasing hazards and vulnerability. This mapping review of articles on tropical cyclone mortality assesses geographic publication patterns, research gaps, and priorities for investigation to inform evidence-based risk reduction.
Methods:
A mapping review of published scientific articles on tropical cyclone-related mortality indexed in PubMed and EMBASE (English) and SINOMED and CNKI (Chinese), focusing on research approach, location, and storm information, was conducted. Results were compared with data on historical tropical cyclone disasters.
Findings:
A total of 150 articles were included, 116 in English and 34 in Chinese. Nine cyclones accounted for 61% of specific event analyses. The United States (US) reported 0.76% of fatalities but was studied in 51% of articles, 96% in English and four percent in Chinese. Asian nations reported 90.4% of fatalities but were studied in 39% of articles, 50% in English and 50% in Chinese. Within the US, New York, New Jersey, and Pennsylvania experienced 4.59% of US tropical cyclones but were studied in 24% of US articles. Of the 12 articles where data were collected beyond six months from impact, 11 focused on storms in the US. Climate change was mentioned in eight percent of article abstracts.
Interpretation:
Regions that have historically experienced high mortality from tropical cyclones have not been studied as extensively as some regions with lower mortality impacts. Long-term mortality and the implications of climate change have not been extensively studied nor discussed in most settings. Research in highly impacted settings should be prioritized.
Airway injuries are the second leading cause of potentially survivable battlefield death and often require airway management strategies. Airway suction, the act of using negative pressure in a patient’s upper airway, removes debris that can prevent respiration, decreases possible aspiration risks, and allows clearer viewing of the airway for intubation. The most important characteristics for a portable airway suction device for prehospital combat care are portability, strong suction, and ease of use.
Methods:
This market review searched academic papers, military publications, Google searches, and Amazon to identify devices. The search included specific characteristics that would increase the likelihood that the devices would be suitable for battlefield use including weight, size, battery life, noise emission, canister size, tubing, and suction power.
Results:
Sixty portable airway suction devices were resulted, 31 of which met inclusion criteria – 11 manually powered devices and 20 battery-operated devices. One type of manual suction pump was a bag-like design with a squeezable suction pump that was extremely lightweight but had limited suction capabilities (vacuum pressure of 100mmHg). Another type of manual suction pump had a trigger-like design which is pulled back to create suction with a firm collection canister that had increased suction capabilities (vacuum pressures of 188-600mmHg), though still less than the battery operated, and was slightly heavier (0.23-0.458kg). Battery-operated devices had increased suction capabilities and were easier to use, but they were larger and weighed more (1.18-11.0kg).
Conclusion:
Future research should work to lighten and debulk battery-operated suction devices with high suction performance.
Hospitals are vulnerable to terrorist attacks, as they must remain easily accessible to the general public. Hospitals are also occupied with both staff and patients 24 hours a day, 365 days a year, meaning that any attack is almost guaranteed to inflict a multitude of casualties. In addition to the immediate effects of attacking a hospital, there are also uniquely devastating second- and third-order effects when hospitals are attacked.
Methods:
A focused search of the Global Terrorism Database (GTD) was performed to identify terrorist attacks against hospitals throughout the world. Data between the years 1970-2018 were selected, which included 191,465 entries in total. These entries were then searched for incidents containing the term “hospital” and the results were manually searched to identify trends in the number of incidents occurring per year, as well as the armament that was employed, and the regions of the world where the attacks occurred.
Results:
A total of 430 terrorist attacks on hospitals were identified in the GTD, resulting in 1,291 deaths and an additional 1,921 wounded. The frequency of terrorist attacks against hospitals has been steadily increasing over the last two decades and is disproportionate to the overall increase in terrorist attacks against all target types. Attacks have been carried out against hospitals in 61 different countries. The most common method used in these attacks was “bombing/explosion,” which accounted for 299 attacks. Of the known terrorist groups identified in the GTD, “Houthi extremists (Anshar Allah)” and “Islamic State of Iraq and the Levant (ISIL)” carried out the greatest number of attacks on hospitals.
Conclusion:
There has been a disproportionate rise in the frequency of terrorist attacks on hospitals when compared to other target types, highlighting the vulnerability of these key structures. Unsurprisingly, these attacks have inflicted large casualty counts in addition to disrupting community health care and disaster response. Attacks against hospitals have been reported on every inhabited continent except Australia, making their protection a matter of international security. The rate of terrorist attacks on hospitals has increased dramatically over the last two decades, creating an urgent need to develop improved defense strategies that will better ensure their protection.
Mass gatherings (MGs) often bring together professionals and organizations that collaborate irregularly or have never engaged in joint working. They involve interaction and communication among multiple and diverse services, which can often prove challenging. Planning such an event is of paramount importance for its success, and interorganizational communication ranks among its most important aspects. Nonetheless, there is limited empirical evidence to support interagency communication in MGs.
Objective:
This study used the 2017 Athens Marathon (Athens, Greece) as the empirical setting to examine how interorganizational communication was perceived among the multiple public health and safety professionals during the planning and implementation phase of the event.
Methods:
Data comprised 15 semi-structured in-depth interviews with key informants, direct observations of meetings and the event itself, and documentary analysis. Open coding and thematic analysis were used to analyze the data.
Results:
Findings indicated three key components of interorganizational communication in such an event: (1) shared situational awareness; (2) interorganizational understanding; and (3) implementing liaison officers.
Conclusion:
This study outlined the factors that influenced interorganizational communication before and during a MG. Practical implications arising from this study may inform the way organizers of marathons and other mass sporting events can engage in effective interorganizational communication.
