Background: Cameroon is amongst the worst affected countries by road traffic injuries with an estimated 1443 disability-adjusted life years per 100,000 population. There have been very limited reports on the crucial prehospital response to road traffic injuries in Cameroon. This study aimed to identify prehospital factors associated with RTI mortality in Cameroon. Methods: We included patients enrolled between June 2022 and March 2023 in the Cameroon Trauma Registry. Information about prehospital factors and demographic data was obtained from patients or their proxies. We examined the association of prehospital care factors like care at the crash scene and type of transportation during crash with final patient outcome. We used Chi-squared test to investigate the association between selected independent variables and mortality. A multivariable logistic regression model was built to identify independent predictors of dying from an RTI. Results: RTIs constituted 69.5% (n = 3203) of all injuries in the Cameroon Trauma Registry. Only 20.7% (n = 102) of 4 + wheel vehicle occupants had seatbelts on and just 2.7% (n = 53) of motorcycle riders were wearing helmets during the collision. Only 4.9% (n = 156) of patients received any form of scene care. In-hospital mortality was 4.3% (n = 139) and was associated with male sex (AOR = 1.7, 95%CI = 1.08–2.80), crashing on a motorcycle (AOR = 2.08, 95%CI = 1.1–3.67) and scene care (AOR = 0.25, 95%CI = 0.04–0.80). Conclusions: Receiving any type of care at the scene such as bleeding control or being placed in the recovery position by bystanders is associated with improved survival. Improving on existing informal prehospital care responses should be a priority in Cameroon. [ABSTRACT FROM AUTHOR]

Background: US nursing homes were ground zero for COVID-19 and nursing home leaders faced multiple challenges to keep residents and staff safe. Understanding the leader’s role and their use of external resources to rapidly respond to the pandemic is important to better prepare for the next infectious disease outbreak emergency. The purpose of this study is to describe Missouri nursing home leaders’ use of external resources to manage challenges encountered during the pandemic. Methods: This qualitative descriptive study uses data from semi-structured interviews conducted with leaders from 24 Midwestern nursing homes between March 2022 and March 2023. Interviews were transcribed verbatim and analyzed using Dedoose software. Directed content analysis, guided by Donabedian’s Structure, Process, Outcome framework, was used for analysis. Interviews were conducted as part of a larger mixed-methods study focused on developing knowledge and recommendations to improve US nursing homes’ capacity to respond to infectious disease outbreaks. Results: Forty-three interviews were conducted across the 24 homes. Participants included administrators (n = 24), nurse leaders (n = 19), and infection preventionists (n = 16). Six sub-categories of external resources/support were used by leaders to manage challenges during the pandemic:1) corporate support and communications, 2) statewide resources, 3) community-based resources, 4) health care coalitions focused on emergency response planning, 5) existing affiliations with local organizations i.e., hospitals, and 6) community members and families. Corporate support was a primary resource; however, it was limited to chain-based homes. Leaders from standalone homes seemed most reliant on statewide agencies, existing affiliations, and other community-based resources due to their lack of corporate connections. Health care coalitions were few, but when available, helped nursing homes prepare for the pandemic onset. Family and community members were vital despite being off-site from nursing homes at the pandemic onset. Conclusion: Leaders played a pivotal role in accessing and using external resources to manage challenges during the pandemic. Statewide and community-based agencies and existing affiliations were particularly critical for standalone homes who otherwise had little to no means of support. Federal, state and local agencies must consider opportunities to build multi-agency regional collaborations, local health care coalitions and community-based partnerships that include nursing homes as member. Finally, community members and family were important in providing support, thus closing visitation is a double-edged sword that needs careful, future consideration. [ABSTRACT FROM AUTHOR]

Underground gas storage is an important facility for regulating the supply and demand of natural gas, optimising the allocation of gas sources and ensuring the safety of gas supply. The traditional emergency response mechanism for gas storage often relies on emergency response agents’ experience and judgement, while there is a lack of a systematic and scientific decision support method to ensure the efficient transfer of information in the emergency response process and maximize the benefits of emergency response scheme. A gas storage reservoir emergency response optimization method was proposed, which constructs a gas storage reservoir emergency response model using the intelligent body cooperative response modeling language. Besides, a method of calculating the disposal benefit of emergency response scheme based on the depth-first search strategy was presented, which determines the optimal cooperative response scheme by using the benefit rate as a robustness indicator of the emergency response cooperative scheme. Finally, taking the emergency response process of Chongqing Xiangguosi Gas Storage Reservoir as an example, a case study was conducted. The results show that compared with the original emergency response scheme, the optimal cooperative response scheme reduces the end-of-response elapsed time by 38. 4% and improves the rate of return by 26. 61% . The coordinated response scheme combined with the optimisation algorithm is effective in reducing time consumption and increasing disposal yield [ABSTRACT FROM AUTHOR]

Aim: To map the commonly used quantitative blood loss measurement methods in clinical practice and provide a solid foundation for future studies. Design and Method: This study adhered to the JBI methodology for scoping reviews and preferred reporting items for systematic reviews and meta‐analyses extension for scoping reviews. We conducted a literature search using five databases to retrieve articles published between January 2012 and September 2022. The search was repeated on 29 February 2024. Data extraction and verification were carried out by two independent researchers using a self‐designed data extraction form. Results: Ultimately, 26 studies published between 2012 and 2024 were considered eligible for inclusion. Six categories of methods were identified from the 26 articles. Among the included studies, only two involved randomized controlled trials, with the majority being observational studies. The World Health Organization (2012) version of the postpartum haemorrhage diagnostic criteria was predominantly used in most studies. Gravimetric and volumetric methods emerged as the most commonly used methods for quantifying postpartum haemorrhages. The timing of blood collection was inconsistent among the included studies. Only 12 studies mentioned measures for the management of amniotic fluid. Conclusions: This scoping review supports the replacement of the visual estimation of blood loss with quantitative assessment methods. Supporting a specific assessment approach is not feasible due to the variability of the study. Future research should focus on establishing the best practices for specific quantitative methods to standardize the management of postpartum haemorrhage and reduce the incidence of postpartum haemorrhage‐related adverse outcomes. Relevance to Clinical Practice: Healthcare professionals need to acknowledge the low accuracy of visual estimation methods and implement quantitative methods to assess postpartum blood loss. Given the limitations inherent in each assessment method, quantification of blood loss should be combined with assessment of maternal vital signs, physiologic indicators and other factors.

As the receiving terminal of liquefied natural gas (LNG), the efficient emergency response of the floating storage and regasification unit (FSRU) is crucial to ensure the safety of LNG transportation at sea. However, few existing literature study the risk issues of FSRUs during emergency operations. In order to improve the emergency response capability of FSRU, this study proposes an innovative assessment method to identify hazards, quantify and rank the risks associated with emergency response and disposal operations of FSRU accidents. Firstly, a comprehensive index hierarchy system applicable to human, equipment, environment, and management aspects of emergency response and disposal operations of FSRU accident is established through an extensive literature review, analysis of accident reports, and expert judgments. Secondly, based on the concept of Intuitionistic Fuzzy Numbers, the Intuitionistic Fuzzy Hybrid Weighted Euclidean Distance (IFHWED) operator is used to enhance the conventional FMEA approach. This method considers the varying levels of expert confidence and integrates subjective and objective weights of risk influential factors (RIFs), and the efficacy is validated through sensitivity analysis. Finally, a comprehensive evaluation model employing the Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation algorithms is used to aggregate the risk values of RIFs. The findings of this study offer decision-makers insights into risks during emergency operation, provide valuable guiding strategies for FSRU accident management, and improve the capability for emergencies at sea.

The current literature mainly uses hub capacity or transport route selection to manage the congestion of emergency multimodal transport and pays less attention to transshipment scheduling. This paper proposes an integrated optimization problem of transport routes and transshipment sequences (ITRTSP) and constructs a hybrid flow shop scheduling model to describe it. Based on this model, a recursive method is proposed to calculate the minimum waiting times that cargoes consume in queues at hubs, given the transport routes and transshipment sequences. Furthermore, a memetic algorithm is designed with route selection as the outer layer and transshipment sequence selection as the inner layer for solving ITRTSP. Compared with existing achievements, the model and algorithms can quantify the dependency between transshipment sequence selection and emergency transport time in multimodal transport network settings. The model and algorithms are applied to solve some real-scale examples and compared with the first-come-first-served (FCFS) rule commonly used in the current literature. The results indicate that the makespan is reduced by up to approximately 4.2%, saving 33.68 h. These findings demonstrate that even with given hub capacities and transport routes, congestion can still be managed and the schedule optimized through transshipment scheduling, further improving emergency transport efficiency.

Many school nurses experienced increased work burden and stress during the COVID-19 pandemic. This analysis examined data from a Centers for Disease Control and Prevention cross-sectional, nationwide survey of school nurses in March 2022 to examine associations between school nurses' ability to conduct their core responsibilities and selected nurse and school factors among school nurses during the 2021–2022 school year and COVID-19 pandemic. Perceived adequate staffing and financial compensation reduced the odds of reported difficulties across all core school nursing tasks. Nurses without a registered nurse license and with higher caseloads were more likely to report difficulty in implementing specific tasks. The impact of these factors varied, with inadequate financial compensation having the largest association with school nurses' difficulty implementing all the core responsibilities. The study results improve our understanding of school nurses' challenges in implementing core school nursing responsibilities during the COVID-19 pandemic in the 2021–2022 school year.

As society becomes more complex, the importance of quick and effective emergency response systems gets more emphasized. This paper introduces a way to reduce the time it takes for emergency staff assembly to be handled during radioactive accidents, which is one of significant factors to manage early stage situations. Using a type of computer modeling called agent-based modeling (ABM) on the NetLogo software, we examine how emergency responses are carried out, focusing on how emergency staff assembly workers are sent out and how they work together in a simulated setting. By integrating traffic and path-finding models, along with real-world GIS (Geographic Information System) data, our methodology allows for more realistic evaluation of response times under various scenarios, including harsh weather conditions (e.g., Heavy snow) and infrastructural disruptions (e.g., Earthquake). The findings reveal significant variability in emergency staff assembly times, underscored by the impact of environmental factors. This research not only contributes to the understanding of emergency response mechanisms but also provides a practical framework for improving the efficacy of disaster management systems, thereby enhancing public safety and resilience against future radiological events.

In recent years, the rapid advancement of technology has paved the way for innovative solutions aimed at enhancing personal safety and security. Among these, wearable Internet of Things (IoT) devices have emerged as a significant development, particularly in safeguarding vulnerable groups such as women and children. This paper introduces a smart security solution that leverages wearable IoT systems to provide real-time monitoring and protection. The increasing incidence of crimes against women and children highlights the urgent need for effective safety measures. Traditional security approaches often fall short in offering immediate assistance or preventive measures. However, wearable IoT devices, equipped with sensors and connectivity features, offer a proactive approach to security. These devices can monitor various physiological and environmental parameters, detect potential threats, and trigger timely alerts to guardians or authorities Our proposed smart security solution integrates advanced IoT technologies with user-friendly wearable devices designed specifically for women and children. This system encompasses several critical components, including GPS tracking, real-time communication, health monitoring, and emergency alert mechanisms. By harnessing the power of IoT, this solution aims to provide continuous protection, enhance situational awareness, and facilitate rapid response in case of emergencies. In this paper, we will explore the design, functionality, and potential impact of wearable IoT devices in improving the safety and security of women and children. We will also discuss the challenges and considerations in implementing such systems, including privacy concerns, data security, and the need for reliable connectivity. Through this comprehensive examination, we aim to demonstrate the viability and importance of IoT-based wearable technology in fostering a safer environment for vulnerable populations.

ABSTRACT Accessibility between fire hydrants and buildings is paramount in emergency response, significantly influencing the efficiency and effectiveness of firefighting operations in the event of an incident. However, assessing this relationship within a geographic information system (GIS) framework presents challenges on two fronts. Obtaining the path avoiding building and parcel obstructions to hydrants is not trivial. Further, determining the furthest extent around a building exterior from hydrants is complicated, yet it is critically important given the spatial limitations of equipment reach. To assess furthest extent, an analytical framework is introduced based on the Euclidean shortest path problem. The proposed approach offers a comprehensive, automated GIS‐based methodology tailored to evaluate the dynamic relationship between hydrants and buildings. The developed methods are able to accurately and precisely identify the furthest point around a building structure from hydrant, facilitating risk assessment as well as fire code compliance. This enables a comprehensive evaluation of potential loss and structure vulnerability at property, street, neighborhood, and regional levels. [ABSTRACT FROM AUTHOR]

This paper explores the potential role of the private sector, particularly the crop protection industry, in enhancing emergency pest prevention, preparedness and response (EPPPR) in relation to invasive pests. By leveraging their position and knowledge, private companies can contribute significantly to mitigating pest-related risks, enabling sustainable responses. We outline a comprehensive framework for EPPPR, covering prevention, preparedness, early detection, emergency response and integrated pest management, and we discuss how the private sector can contribute to this framework. We highlight the value that greater private sector involvement could bring to emergency pest prevention, preparedness and early pest detection through its on-the-ground networks and data-sharing capabilities with national plant protection organisations. Additionally, we stress the importance of robust and agile regulatory frameworks and policies for creating an enabling environment for the effective management of emergency pest outbreaks. We also emphasise the potential opportunities provided by private sector investment in research and development in driving innovation in pest management technologies. By fostering partnerships with governments, international organisations, local communities and other stakeholders, the private sector can play a vital role in building a resilient agricultural system capable of withstanding pest challenges.

Emergency response decision making is crucial in managing critical incidents; however, several studies have demonstrated the negative effects of decision inertia. Understanding the manifestation and impact of decision inertia, as well as utilising extended reality (XR) technology with 360-degree immersion, should enhance decision making in high-stress environments and improve emergency response efforts. This study investigated decision inertia, using 109 participants, in an XR 360-degree environment and its impact on decision-making outcomes. The findings revealed that participants often opted for a sub-optimal outcome, and decision inertia scores varied across these outcomes. Linear regression analysis demonstrated that decision inertia scores significantly predicted decision outcomes, with higher decision inertia scores associated with sub-optimal decision-making. Participants prior moral decision-making did influence subsequent immersive reality decision outcomes and demonstrated a Bayesian updating effect. The Structured Tabular Thematic Analysis highlighted the importance of information validity, decision confidence, and scenario fidelity in decision-making within the immersive environment. The study provides insights into decision inertia in immersive virtual reality critical incidents and offers practical solutions for improving decision-making processes in emergency response contexts.

In a nuclear emergency, consequence assessment based on the plant conditions using a simple method is important for a prompt response. Response Technical Manual (RTM-96) is a manual calculation method for prompt dose projection at arbitrary distances by converting pre-calculated doses with the conversion factor based on distance and weather. However, the 'conversion factor' in RTM-96 does not consider accident scenarios with filtered containment venting system (FCVS). Therefore, in this study, we defined the ratio of effective dose between 1 km and an arbitrary distance as the 'Distance Conversion Factor (DCF)' and aimed to clarify the difference between DCFs by accident scenarios, focusing on the presence or absence of FCVS. The results showed that the differences in DCFs for different accident scenarios were minor in the case of no rainfall. In contrast, in the case of rainfall, DCF differed significantly with scenarios with FCVS and those with containment failure. Therefore, the authors propose that DCFs with rainfall should be calculated separately for several representative accident scenarios rather than uniformly for all accident scenarios, as in the conventional method. The results can contribute to developing a new prompt consequence assessment method, such as RTM-96, which considers FCVS. [ABSTRACT FROM AUTHOR]

Urban communities have long been pivotal in wealth creation and technological innovation. In the contemporary context, their modus operandi is intricately tied to a diverse array of critical infrastructure systems (CISs). These systems—encompassing utilities, transportation, communication, and more—are indispensable for daily life; however, historical lessons underscore that the ever-growing interdependence among modern CISs has sapped their robustness. Furthermore, this vulnerability is compounded by the intensifying natural hazards catalysed by climate change, leaving urban communities with eroded resilience. Against this backdrop, pilot studies have harnessed breakthroughs in artificial intelligence (AI) to chart a new course toward resilient urban communities. This paper illuminates AI-driven resilience by reviewing the latest research in key aspects including (1) the limitation of state-of-the-art resilience assessment frameworks; (2) emergency response as a novel blueprint featuring swift response following catastrophes; (3) efficient loss assessment of CISs using AI algorithms; and (4) machine-learning-enabled autonomous emergency response planning. The remaining challenges and hardships faced on the journey toward resilient urban communities are also discussed. The findings could contribute to the ongoing discourse on enhancing urban resilience in the face of increasingly frequent and destructive climate hazards. [ABSTRACT FROM AUTHOR]

Many cities across the United States (U.S.) face threats from natural hazards, and as climate change continues to worsen, cities will face increased risks. Emergency management helps cities to mitigate these risks and adapt to shifting threats. Based on the Rockefeller City Resilience Framework and City Resilience Index Driver 3, Indicator 3.4, the scope of this research was to develop an emergency management maturity model and explore emergency management capacity for future disasters based on an assessment of five cities across the U.S. With the resulting data, a city's score would serve as an evaluation of the emergency response indicator (Indicator 3.4) in order to eventually enter the City Resilience Index. The cities selected were Buffalo, New York; Honolulu, Hawaii; Memphis, Tennessee; New Orleans, Louisiana; and Saint Paul, Minnesota, based on their hazard/risk factors. It should be noted that these scores were intended to compare resilience in a city over time and identify unique areas in which the cities could improve emergency management and were not meant to rank the cities against each other. An interesting find was the overlap between the counties and cities regarding policy data, creating a new avenue for research in local level emergency management. [ABSTRACT FROM AUTHOR]

In recent years, the landscape of disasters, conflicts and terror events has become more frequent and complex. Climate change, armed conflicts, terrorism, disinformation, cyber‐attacks, inequality and pandemics now present significant challenges to humanity. Emergency physicians today are likely to encounter ideologically motivated violent extremism or terrorist actions by radicalised lone actors. Terror medicine, distinct from disaster medicine, addresses the unique and severe injuries caused by terrorist incidents, including explosions, gunshots and chemical agents. The chaotic aftermath of such attacks demands rapid triage, prioritisation and strict adherence to scene safety protocols. Moreover, terrorist events have profound psychological impacts on victims and responders alike. Understanding the broader public health implications of these attacks is crucial for emergency physicians to enhance community safety and resilience. Terror medicine also brings unique ethical and legal challenges, such as patient confidentiality, mandatory reporting and mass casualty management. Effective responses to terror incidents necessitate close collaboration between healthcare providers and law enforcement. Familiarity with terror medicine principles fosters better communication and coordination, ultimately improving response efficiency and patient outcomes. This review offers a comprehensive approach to understanding terror medicine, defining the concept of ‘terror’, its significance for emergency physicians, and the known health impacts on patients, healthcare workers and responders. By delving into these aspects, the review aims to equip medical professionals with the knowledge and skills needed to navigate the complexities of terror‐related emergencies effectively.

The frequency of natural disasters has increased recently, posing a huge threat to human society. Rapid, accurate, authentic, and comprehensive acquisition and transmission of disaster information are crucial in emergency response. In this paper, we propose a design scheme for an aerial remote sensing platform based on real-time satellite communication. This platform mainly includes a civilian heavy-duty unmanned aerial vehicle, ground observation system with the self-developed orthographic image stabilization device, wireless communication system with an airborne mobile communication device using Ku band, ground satellite information receiving station, and data processing and application analysis system. The image stabilization capability of the ground observation system and the communication capability of the wireless communication system were verified through ground and flight tests respectively. The results showed that the stability accuracy of the platform was better than the theoretical threshold, the system transmission rate was not less than 2 M bandwidth, the data packet loss rate was low, and the time delay was not more than 2 s. The images captured in the experiment were clear, with a resolution of less than 1cm and an overlap rate of more than 70%. These all results meet the emergency observation requirement, which indicates that the aerial remote sensing platform based on real-time satellite communication has great potential for application in natural disaster emergency response.

This review explores the impact of telemedicine, mobile health (mHealth) applications, and point-of-care ultrasound in disaster scenarios. A comprehensive literature review was conducted using databases such as PubMed, MEDLINE, and Google Scholar to identify relevant studies on technology in disaster medicine. The findings indicate that telemedicine significantly enhances communication and coordination among emergency teams, mHealth applications improve patient tracking and triage, and point-of-care ultrasound provides rapid and accurate diagnostics in disaster settings. These technological advancements have contributed to efficient and effective disaster response efforts, highlighting the critical role of technology in modern disaster medicine.

Background: The healthcare sector witnessed the occurrences and impacts of disruptions on supply chains during the coronavirus disease (COVID-19) pandemic. Consequently, it is essential to strengthen institutional medical supply chain systems by addressing the key attributes of strategic stockpile plan renewal: flexibility, traceability and transparency, perseverance and responsiveness, global independence, and equitable access. Aim and objective: To establish a resilient supply chain integrated into the emergency management cycle by proposing a sustainable 5P Strategic Medical Stockpile model. Settings: Online evidence, available literature, and lessons learned during the COVID-19 response in the Emirate of Abu Dhabi. Methods: This review employed a systematic methodology of identification, selection, assessment, synthesis, and interpretation of data from peer-reviewed articles, review reports, and response frameworks spanning the years 2012 to 2020. Additionally, media reports and announcements were analyzed to determine the implications of COVID-19 on the supply chain from 2020 to 2022. Recommendations are formulated in response to the identified shortcomings revealed during the review process, as well as considering experiences and lessons resulting from responses to address COVID-19 in the Abu Dhabi Health Sector. Results: Our analysis revealed a deficiency in effective operational protocols for building a robust supply chain. The experience gained from responding to COVID-19 has highlighted deficiencies such as unclear issues with stockpiles, inadequate resources, insufficient planning, the absence of established procedures, and a lack of performance monitoring. The pandemic had a tremendous impact on health systems and medical supply chains worldwide. Our suggested model necessitates aligning responses with national contingency protocols. Accountability may fluctuate during each phase of an emergency, depending on decision-making authority and jurisdictional capabilities. Conclusion: The proposed 5P model can support policymakers, health regulators, institutions, and professionals in formulating strategies to establish a resilient stockpile system that serves as a medical supply chain buffer when supplies are not instantly accessible.

Participants responded to a comprehensive online questionnaire comprising 22 questions across seven sections covering aspects of emergency response, disaster management, and infection control. The study targeted a minimum sample size of 500 participants, successfully garnering responses from 512 individuals.Results: Of the 512 participants, 59.9% (n=312) were healthcare providers in patient-facing roles, and 40.1% (n=209) were in non-patient-facing roles. The results revealed notable disparities in awareness and preparedness between these two groups. Healthcare providers demonstrated higher awareness levels compared to their non-patient-facing counterparts. For instance, 76.9% of healthcare providers were aware of the hospital’s emergency response plan compared to 56.2% of non-healthcare providers (χ² = 52.165, p < 0.001). Similar disparities were observed in understanding the term “disaster” (86.5% vs 54.1%, χ² = 27.931, p < 0.001), and awareness of a command center (73.4% vs 45.2%, χ² = 42.934, p < 0.001).Discussion: These findings underscore the critical need for enhancing awareness, education, and preparedness within healthcare facilities, emphasizing an integrated approach that includes both healthcare and non-healthcare staff. By addressing these gaps, healthcare facilities can significantly improve their emergency response efficiency, disaster management capabilities, and infection control measures, thereby enhancing the overall safety and quality of patient care.Keywords: disaster preparedness, emergency response, inter-professional collaboration, healthcare management, infection control, emergency medicine training, patient safety, cross-sectional analysis

Abstract Objective Given the frequency of disasters worldwide, there is growing demand for efficient and effective emergency responses. One challenge is to design suitable retrospective charts to enable knowledge to be gained from disasters. This study provides comprehensive understanding of published retrospective chart review templates for designing and updating retrospective research. Methods We conducted a systematic review and text analysis of peer-reviewed articles and grey literature on retrospective chart review templates for reporting, analysing, and evaluating emergency responses. The search was performed on PubMed, Cochrane, and Web of Science and pre-identified government and non-government organizational and professional association websites to find papers published before July 1, 2022. Items and categories were grouped and organised using visual text analysis. The study is registered in PROSPERO (374,928). Results Four index groups, 12 guidelines, and 14 report formats (or data collection templates) from 21 peer-reviewed articles and 9 grey literature papers were eligible. Retrospective tools were generally designed based on group consensus. One guideline and one report format were designed for the entire health system, 23 studies focused on emergency systems, while the others focused on hospitals. Five papers focused specific incident types, including chemical, biological, radiological, nuclear, mass burning, and mass paediatric casualties. Ten papers stated the location where the tools were used. The text analysis included 123 categories and 1210 specific items; large heterogeneity was observed. Conclusion Existing retrospective chart review templates for emergency response are heterogeneous, varying in type, hierarchy, and theoretical basis. The design of comprehensive, standard, and practicable retrospective charts requires an emergency response paradigm, baseline for outcomes, robust information acquisition, and among-region cooperation.

Abstract Background The COVID-19 pandemic had a disproportionate impact on the health and wellbeing of people who use drugs (PWUD) in Canada. However less is known about jurisdictional commonalities and differences in COVID-19 exposure and impacts of pandemic-related restrictions on competing health and social risks among PWUD living in large urban centres. Methods Between May 2020 and March 2021, leveraging infrastructure from ongoing cohorts of PWUD, we surveyed 1,025 participants from Vancouver (n = 640), Toronto (n = 158), and Montreal (n = 227), Canada to describe the impacts of pandemic-related restrictions on basic, health, and harm reduction needs. Results Among participants, awareness of COVID-19 protective measures was high; however, between 10 and 24% of participants in each city-specific sample reported being unable to self-isolate. Overall, 3–19% of participants reported experiencing homelessness after the onset of the pandemic, while 20–41% reported that they went hungry more often than usual. Furthermore, 8–33% of participants reported experiencing an overdose during the pandemic, though most indicated no change in overdose frequency compared the pre-pandemic period. Most participants receiving opioid agonist therapy in the past six months reported treatment continuity during the pandemic (87–93%), however, 32% and 22% of participants in Toronto and Montreal reported missing doses due to service disruptions. There were some reports of difficulty accessing supervised consumption sites in all three sites, and drug checking services in Vancouver. Conclusion Findings suggest PWUD in Canada experienced difficulties meeting essential needs and accessing some harm reduction services during the COVID-19 pandemic. These findings can inform preparedness planning for future public health emergencies.

Purpose The benefits of pharmacists' involvement in medical emergencies are well established, but optimal methods of training pharmacists for emergency response are unknown. The primary objective of this report is to describe the design and evaluation of a pharmacy resident medical emergency response training (PR-MERT) program for preparing trainees to respond to hospital medical emergencies, including cardiac arrest and rapid sequence intubation (RSI). Summary The PR-MERT program was a year-long longitudinal experience designed to prepare postgraduate year 1 pharmacy residents for medical emergency response. During the first month, the residents completed an orientation session that encompassed several lectures, certification by the American Heart Association in basic life support and advanced cardiovascular life support, standardized simulation scenarios, and mock medical emergencies. The trainees continued to utilize these skills and clinical knowledge through a longitudinal didactic lecture series, resident case conferences, and practice-based application by responding to real-life medical emergencies. Residents were assessed and coached throughout the program by clinical pharmacy preceptors and a "code coach" with extensive medical emergency response experience. After the year-long training, residents completed an anonymous survey assessing self-confidence and the structure of the program. The results showed improved confidence in medication selection and dosing, as well as anticipating the needs of the team and speaking up in cardiac arrest and RSI situations. Residents were satisfied with the training offered and structure of the program. Conclusion The development of a PR-MERT program at an academic medical center was successful in achieving longitudinal learning objectives and improving residents' confidence in responding to medical emergencies. The implementation of a similar medical emergency training curriculum in inpatient pharmacy residency programs may be beneficial. [ABSTRACT FROM AUTHOR]

Introduction: In urban areas exposed to high-magnitude earthquakes, the drinking water supply would be severely damaged, and domestic services would be disrupted for a large part of the population in the event of an earthquake. The Lima-Callao metropolitan area in Peru, South America, is expected to experience an 8.8 Mw earthquake, and it is estimated that approximately 90% of the population would not have immediate access to emergency water in the case of such an event. The main objective of this paper is to define criteria for a spatial analysis method to guide the design criteria for an Emergency Water Supply System (EWaSS). Methods: This paper combines territorial, urban resilience and participatory approaches and presents the results of an interdisciplinary research with social impact. Thus, it examines the urban territory at macro-, meso- and micro scales; physical-spatial variables indicating risk levels and possible public spaces to implement the system; and socio-spatial variables regarding the population, risk perception and participation in management to strengthen urban resilience. Normative tools and the Geographic Information System are used to spatialize and systematize quantitative and qualitative information. Results and discussion: The EWaSS is an alternative for safe water supply in a post-disaster situation that would provide immediate and autonomous operation during the first 72 h of the emergency. The results show the physical-spatial and social viability of urbanized areas and the system design criteria that guide local actors in making decisions at the three levels of emergency management.

Industrial fires at facilities including waste management sites, warehouses, factories, chemical works, and fuel storage depots are relatively frequent occurrences. Often, these fires occur adjacent to urban communities and result in ground-level airborne pollutant concentrations that are well above guideline values. Land, water, livestock, and crops may also be contaminated by the emissions and by firefighting activities. Moreover, impacted communities tend to have a higher proportion of minority ethnic populations as well as individuals with underlying health vulnerabilities and those of lower socio-economic status. Nevertheless, this is an aspect of air quality that is under-researched, and so this review aims to highlight the public health hazards associated with industrial fires and the need for an effective, coordinated, public health response. We also review the range of monitoring techniques that have been utilised in such fires and highlight the role of dispersion modelling in predicting plume trajectories and in estimating population exposure. We recommend establishing 1 h guideline values for particulate matter to facilitate timely public health interventions, and we highlight the need to review regulatory and technical controls for sites prone to fires, particularly in the waste sector.

Explosion in the military zone emergency response plan includes the process of preparedness, risk reduction, and normalization of the emergency. A bomb blast causes human and financial losses to people. Therefore, to prepare and reduce the risk, it is necessary to simulate a bomb blast in a military zone. For this purpose, in this study, the risk of a bomb blast containing ethane, methane, and propane fuel was simulated by the Baker-Strehlow-Tang explosion method in the form of 3 scenarios. According to this method, at a distance of 6, 4.5, and 5 km from the place of ethane, methane, and propane bombs explosion, respectively, the amount of impulse caused by the explosion is reduced by 50%. According to these results, it is clear that the overpressure explosion of ethane, methane, and propane bombs in the military zone is not directly related to the distance from the site of the explosion. The pulse from the explosion of ethane, methane, and propane bombs occurs in one second and will be the same at all distances. [ABSTRACT FROM AUTHOR]

Recently, frequent flood disasters in China have seriously threatened economic development and public safety. This paper addresses the need for a dynamic urban flood emergency knowledge management system in emergency management departments and the lack of systematic knowledge among emergency managers regarding urban flood control. A multimodal knowledge graph-based urban flood emergency knowledge management model was constructed to enhance the decision-making capabilities of emergency management departments, improve the efficiency of public emergency evacuation, and reduce losses from urban flood disasters by analyzing the shortcomings of the existing emergency management system. An intelligent and dynamic flood emergency knowledge management model was built. This paper integrates multimodal knowledge graph technology to establish a multimodal emergency knowledge management framework for urban flood control. It develops and simulates the proposed model's application scenarios for urban flood emergency evacuation using the Flocking algorithm on the NetLogo platform. Through simulation experiments, the practicality and effectiveness of the model in real flood disaster situations were examined, particularly in simulating crowd evacuation behavior. The study found that the model significantly improves the accuracy of information and decision-making speed during emergency responses and supports emergency management departments in conducting targeted and personalized emergency decisions. This research provides a scientific basis for emergency management departments to optimize their emergency response strategies to flood disasters and serves as a reference and example for the application of multimodal knowledge graph technology in emergency management.

The Internet of Things (IoT) is a growing network of interconnected devices used in transportation, finance, public services, healthcare, smart cities, surveillance, and agriculture. IoT devices are increasingly integrated into mobile assets like trains, cars, and airplanes. Among the IoT components, wearable sensors are expected to reach three billion by 2050, becoming more common in smart environments like buildings, campuses, and healthcare facilities. A notable IoT application is the smart campus for educational purposes. Timely notifications are essential in critical scenarios. IoT devices gather and relay important information in real time to individuals with special needs via mobile applications and connected devices, aiding health-monitoring and decision-making. Ensuring IoT connectivity with end users requires long-range communication, low power consumption, and cost-effectiveness. The LPWAN is a promising technology for meeting these needs, offering a low cost, long range, and minimal power use. Despite their potential, mobile IoT and LPWANs in healthcare, especially for emergency response systems, have not received adequate research attention. Our study evaluated an LPWAN-based emergency response system for visually impaired individuals on the Hazara University campus in Mansehra, Pakistan. Experiments showed that the LPWAN technology is reliable, with 98% reliability, and suitable for implementing emergency response systems in smart campus environments. [ABSTRACT FROM AUTHOR]

Objective There is a risk of hydrogen sulfide（H2S） leakage in the production process of high-sulfur oil and gas wells and desulfurization units in refineries, and the efficiency of emergency disposal method mainly based on physical dilution is low, which will affect the emergency rescue. A combined process of gas capture and dry desulfurization is proposed to dispose the leaked hydrogen sulfide, and whether the introduction of air in the leaked gas will affect the safety of dry desulfurization and the performance of desulfurizers is studied. Methods By simulating the dry treatment process of leaked hydrogen sulfide, the sulfur capacity and bed temperature rise of different types of dry desulfurizers such as activated carbon, iron oxide, and zinc oxide were compared and tested, and the desulfurizer with better performance was selected. Taking the optimized desulfurizer as the research object, the effects of space velocity and air content on temperature rise, penetration sulfur capacity, desulfurization accuracy, and side reactions were investigated under different H2S content. Results The 3# desulfurizer with the highest penetration sulfur capacity was selected from 8 kinds of iron oxide desulfurizers from different manufacturers. Under the simulated operating conditions of the original particle size, the penetration sulfur capacity could reach 18.2%. The rise in desulfurizer bed temperature increased with increased hydrogen sulfide content. With the increase of space velocity and air content, it increased rapidly and then tended to be stable or even slightly decreased, and the maximum temperature rise did not exceed 40 ℃. When the air volume fraction exceeded 25%, the sulfur capacity of the desulfurizer increased by about 50%, and there was a significant negative correlation between space velocity and penetration sulfur capacity. When the space velocity was lower than 1 000 h-1, the penetration sulfur capacity exceeded 25%. The desulfurization accuracy and side reactions were not affected by the air content. There was no by-product of sulfur dioxide generating before the penetration of hydrogen sulfide and at a space velocity below 2 000 h-1. Conclusions Using a dry desulfurization process to treat leaked hydrogen sulfide would result in simultaneous desulfurization and regeneration processes, with a specific temperature rise in the bed layer and no by-product of sulfur dioxide generating, which had high safety. The addition of air had a specific improvement effect on the penetration sulfur capacity of desulfurizer. When the air volume fraction was greater than 25%, and the space velocity was lower than 1 000 h-1, it was suitable for dry method emergency response of leaked hydrogen sulfide.

This research sought to determine whether there was a direct relationship between muscle power, muscle endurance and emergency response times among young adults. While performance capability remains an essential component for emergency teams, this study showed how some physical fitness factors might alter initial emergency response time and lessen the effects of the disaster. Engagement in preparedness exercises, particularly those emphasizing physical activity, offers advantageous health outcomes and enhances disaster response efficacy. These improvements in readiness directly impact the overall outcomes of such disasters. The sample consisted of 21 students, comprising both male and female participants of the same age. Following the American College of Sports Medicine's (ACSM) Exercise Preparticipation Health Screening Questionnaire for Exercise Professionals, the participants were separated into two groups: the physically active group and the physically inactive group. The study's main objective was to determine whether muscle power and muscle endurance of the participants could influence their fire emergency response movement time to a safe location. Additionally, the study sought to find out whether physically active participants responded more quickly than physically inactive ones. The findings of this study indicate a relationship between emergency response time and measurements of muscle endurance and muscle power. Participants who were physically active had shorter movement time to safe location (p = 0.023), performed better on the standing broad jump test (p = 0.001), and muscle endurance test (p = 0.004). Although performance ability is a key component for emergency teams, this study demonstrated how some factors of physical fitness can affect initial emergency response time and help mitigate the effects of the disaster in young adults.

Objective: Given the frequency of disasters worldwide, there is growing demand for efficient and effective emergency responses. One challenge is to design suitable retrospective charts to enable knowledge to be gained from disasters. This study provides comprehensive understanding of published retrospective chart review templates for designing and updating retrospective research. Methods: We conducted a systematic review and text analysis of peer-reviewed articles and grey literature on retrospective chart review templates for reporting, analysing, and evaluating emergency responses. The search was performed on PubMed, Cochrane, and Web of Science and pre-identified government and non-government organizational and professional association websites to find papers published before July 1, 2022. Items and categories were grouped and organised using visual text analysis. The study is registered in PROSPERO (374,928). Results: Four index groups, 12 guidelines, and 14 report formats (or data collection templates) from 21 peer-reviewed articles and 9 grey literature papers were eligible. Retrospective tools were generally designed based on group consensus. One guideline and one report format were designed for the entire health system, 23 studies focused on emergency systems, while the others focused on hospitals. Five papers focused specific incident types, including chemical, biological, radiological, nuclear, mass burning, and mass paediatric casualties. Ten papers stated the location where the tools were used. The text analysis included 123 categories and 1210 specific items; large heterogeneity was observed. Conclusion: Existing retrospective chart review templates for emergency response are heterogeneous, varying in type, hierarchy, and theoretical basis. The design of comprehensive, standard, and practicable retrospective charts requires an emergency response paradigm, baseline for outcomes, robust information acquisition, and among-region cooperation.

This paper adds to existing knowledge about flood management in Accra and contributes insights into emergency responses to major flood events in a geospatial context. The study identifies and analyses the specific routes from the facilities of emergency responders to designated flood-prone areas within four sites in the peripheral areas of the Greater Accra Metropolitan Area. Flood hotspots were ascertained from several sources including local knowledge and bluespot maps derived from a 10 m resolution elevation model. GIS-based network analysis was used to determine the fastest routes from emergency responder facilities to flood hotspots, based on OpenStreetMap data. Interviews revealed that the computed routes are unsuitable for emergency services due to narrow passages and prevailing conditions during the floods. It is necessary to incorporate the individual responder’s knowledge gained through familiarization with the local terrain to identify the optimal routes. The study further analysed the accessibility of emergency response services using indicative service area maps that present an account of time-distance from various emergency responders’ bases. Finally, the study recommends the need for better planning of the expanding areas of the Greater Accra Metropolitan Area, in terms of accessibility for emergency responders. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic had a disproportionate impact on the health and wellbeing of people who use drugs (PWUD) in Canada. However less is known about jurisdictional commonalities and differences in COVID-19 exposure and impacts of pandemic-related restrictions on competing health and social risks among PWUD living in large urban centres. Methods: Between May 2020 and March 2021, leveraging infrastructure from ongoing cohorts of PWUD, we surveyed 1,025 participants from Vancouver (n = 640), Toronto (n = 158), and Montreal (n = 227), Canada to describe the impacts of pandemic-related restrictions on basic, health, and harm reduction needs. Results: Among participants, awareness of COVID-19 protective measures was high; however, between 10 and 24% of participants in each city-specific sample reported being unable to self-isolate. Overall, 3–19% of participants reported experiencing homelessness after the onset of the pandemic, while 20–41% reported that they went hungry more often than usual. Furthermore, 8–33% of participants reported experiencing an overdose during the pandemic, though most indicated no change in overdose frequency compared the pre-pandemic period. Most participants receiving opioid agonist therapy in the past six months reported treatment continuity during the pandemic (87–93%), however, 32% and 22% of participants in Toronto and Montreal reported missing doses due to service disruptions. There were some reports of difficulty accessing supervised consumption sites in all three sites, and drug checking services in Vancouver. Conclusion: Findings suggest PWUD in Canada experienced difficulties meeting essential needs and accessing some harm reduction services during the COVID-19 pandemic. These findings can inform preparedness planning for future public health emergencies. [ABSTRACT FROM AUTHOR]

Emergency response vehicles (ERVs) need to move fast, which can lead to potential accidents. A system is proposed to utilize connected vehicle technology for facilitating the movement of multiple ERVs in a two-way roadway. A biobjective model was developed to minimize the ERVs' travel/response times while maximizing safety. The proposed system can help non-ERVs stop in assigned locations and wait for the ERVs to pass. According to mission priority, different types of ERVs (ambulance, fire truck, and police car) can use a travel lane from the opposite direction (contraflow) to move faster. A hybrid nondominated sorting genetic algorithm II-particle swarm optimization (NSGAII-PSO) approach was used to solve the model faster than CPLEX. To evaluate the system's performance, different experiments, including various road types, numbers and types of ERVs, direction priorities, and congestion levels, have been conducted. Results demonstrate that the proposed system can improve the travel time of ERVs that have the priority to use the contraflow lane in cases where the other side of the roadway is less congested and has a shoulder (when opposing ERVs use a two-way roadway simultaneously). The proposed system can eliminate weaving and passing among non-ERVs in all cases compared to two current strategies (going to the right edge and vacating the ERV lane without receiving instructions).

Summary: Drones, unmanned aerial systems, are of growing interest to organizations involved in disaster risk reduction, particularly in post-disaster emergency response. Despite the potential benefits of drones, their use is not well established and practical challenges need to be understood. This study examines the role of drones in disaster management by analyzing various applications of drones in response to the Noto Peninsula earthquake in January 2024. Drones were used on the ground in a variety of new ways, including transport of emergency supplies, restore of cellphone communications, and inspect on damaged facilities. Several issues were identified, including the need to incorporate drone capabilities into disaster management plans, develop appropriate laws and regulations, establish public-private coordination mechanisms, address technological limitations due to advances in technology, and implement training programs specifically for drone operators. Collaboration among government agencies, private organizations, and industry associations in disaster response highlighted the importance of fostering partnerships and mobilizing collective expertise in disaster management. The study concludes by highlighting the important role that drones can play in enhancing emergency response efforts and mitigating the impact of future disasters.

Emergency response plans for tunnel vehicle accidents are crucial to ensure human safety, protect critical infrastructure, and maintain the smooth operation of transportation networks. However, many decision-support systems for emergency responses still rely significantly on predefined response strategies, which may not be sufficiently flexible to manage unexpected or complex incidents. Moreover, existing systems may lack the ability to effectively respond effectively to the impact different emergency scenarios and responses. In this study, semantic web technologies were used to construct a digital decision-support system for emergency responses to tunnel vehicle accidents. A basic digital framework was developed by analysing the knowledge system of the tunnel emergency response, examining its critical elements and intrinsic relationships, and mapping it to the ontology. In addition, the strategies of previous pre-plans are summarised and transformed into semantic rules. Finally, different accident scenarios were modelled to validate the effectiveness of the developed emergency response system.
