Abstract Su505: Impact of a Targeted Automated External Defibrillator (AED) Program on Survival After Ventricular Fibrillation Cardiac Arrest in the Sao Paulo Metropolitan Subway System: A Landmark Initiative in Latin America

The targeted Automated External Defibrillator (AED) program in the Sao Paulo Metro has yielded promising results in improving survival rates for individuals experiencing out-of-hospital cardiac arrest (OHCA) due to ventricular arrhythmias. A longitudinal observational study conducted from September 2006 to November 2023 assessed the program's impact on survival outcomes. The implementation of the full program led to a significant improvement in survival to hospital discharge with minimal neurological impairment (0% vs. 43%, P=0.001). These findings underscore the importance of a targeted AED program in improving survival outcomes for OHCA, particularly in densely populated urban environments such as the Sao Paulo Metro. The short interval between arrest and defibrillation emerged as a critical factor in achieving favorable long-term, neurologically intact survival rates. The success of this program advocates for the strategic expansion of targeted AED initiatives in other large Latin American cities, emphasizing the potential to save lives and enhance public health outcomes through proactive emergency medical response measures.

Variations in access to acute care services by immigrant background and sociodemographic factors

Abstract Background The Emergency Medical Communication Center (EMCC) plays a vital role in the medical emergency response system by triaging contacts, notifying local physicians, and providing medical advice. The utilization of acute care services and the subsequent care pathway by individuals with immigrant background remains unclear in the Norwegian context. This study aims to investigate whether disparities exist in the acute care pathway for patients with different sociodemographic background who use ambulance services. Methods We examined all code red ambulance dispatches for life-threatening emergencies in 2021 in Norway. These ambulance dispatches were linked to primary health care and specialist health care contacts to trace patient pathways and outcomes. Statistical analyses were conducted using linear regression models, adjusted for patient characteristics, such as immigrant background, age, sex, municipality of residence, living condition, socioeconomic status, comorbidity and cause of emergency contact. Results Preliminary crude findings indicate that patients with immigrant background are overrepresented in the groups receiving acute primary care only and underrepresented in the groups transferred directly to specialist health care, within 8 hours after ambulance arrival at the patients’ location. Conclusions The preliminary results suggest challenges for the EMCC in triaging patients with immigrant background, but further research is needed to explore potential systematic differences. This study aims to improve understanding of disparities in access to acute care and inform targeted interventions to optimize resource allocation in emergency departments. Key messages • This study may improve understanding of disparities in access to acute care in Norway. • This study can inform targeted interventions to improve resource allocation in emergency departments.

A Cross-Sectional Analysis of ALS/ BLS Care in Low Acuity 9-1-1 Response by Geography and Insurance Status Utilizing the 2019 NEMSIS Dataset

Purpose. The objective of this study was to examine the relationship between patient acuity and level of EMS care adjusting for rurality and insurance. Methods. Data were obtained from the National Emergency Services Information System (NEMSIS) database for 2019. EMS responses (n = 4,375,568) were analyzed comparing patient acuity and CMS Service level, Advanced Life Support (ALS) vs Basic Life Support (BLS), to assess for associations in acuity and CMS Service level using logistic regression. Results. Overall, there was a decreased odds of advanced life service use at low acuity EMS responses (OR=0.443, 95% CI=0.440-0.445). Sub analysis exploring the interaction between CMS Service Level, Rurality demonstrates an overall trend of decreasing odds of low acuity EMS responses among rural areas and BLS care (OR=0.492, 95% CI=0.486,0.498) and ALS care (OR=0.198, 95% CI=0.197,0.200). When analyzing trends among public vs all other insurance and rural vs urban settings, there were decreases in low acuity ALS care in the rural setting; ALS and Pub Insurance (OR 0.447, 0.444-0.450, p<0.001), ALS and Rural (OR 0.198, CI 0.197-0.914, p<0.001) among low acuity responses. The results indicate that acuity and service level vary according to insurance and rurality. In the low acuity call type, we see decreased odds of ALS use compared BLS use in those with public insurances compared to other insurance. There is also a geographic component to these results where the use of Advance Life Support services declined with decreases in urbanicity. Discussion. These results potentially highlight that rural areas utilize less emergency medical response resources in low acuity responses. As such, EMS programs like community paramedicine, could be potentially effective interventions to close gaps in access to care for rural residents.

Endogeneity of pedestrian survival time and emergency medical service response time: Variations across disadvantaged and non-disadvantaged communities

The Vision Zero-Safe Systems Approach prioritizes fast access to Emergency Medical Services (EMS) to improve the survivability of road users in transportation crashes, especially concerning the recent increase in pedestrian-involved crashes. Pedestrian crashes resulting in immediate or early death are considerably more severe than those taking longer. The time gap between injury and fatality is known as survival time, and it heavily relies on EMS response time. The characteristics of the crash location may be associated with EMS response and survival time. A US Department of Transportation initiative identifies communities often facing challenges. Six disadvantaged community (DAC) indicators, including economy, environment, equity, health, resilience, and transportation access, enable an analysis of how survival and EMS response times vary across DACs and non-DACs. To this end, this study created a unique and comprehensive database by linking DACs data with 2017–2021 pedestrian-involved fatal crashes. This study utilizes two-stage residual inclusion models with segmentation for DACs and non-DACs accounting for the endogenous relationship between EMS response and pedestrian survival time. The results indicate that EMS response time is higher and pedestrian survival time is lower in DACs than in non-DACs. A delayed EMS response time is associated with a greater reduction in survival time in DACs compared to non-DACs. Factors, e.g., nighttime and interstate crashes, contribute to higher EMS response time, while pedestrian drugs, driver speeding, and hit-and-run behaviors are associated with a greater reduction in survival time in DACs than non-DACs. The implications of the findings are discussed in the paper.

Comprehensive Risk Analysis of Emergency Medical Response Systems in Serbian Healthcare: Assessing Systemic Vulnerabilities in Disaster Preparedness and Response.

Emergency Medical Response Systems (EMRSs) play a vital role in delivering medical aid during natural and man-made disasters. This quantitative research delves into the analysis of risk and effectiveness within Serbia's Emergency Medical Services (EMS), with a special emphasis on how work organization, resource distribution, and preparedness for mass casualty events contribute to overall disaster preparedness. The study was conducted using a questionnaire consisting of 7 sections and a total of 88 variables, distributed to and collected from 172 healthcare institutions (Public Health Centers and Hospitals). Statistical methods, including Pearson's correlation, multivariate regression analysis, and chi-square tests, were rigorously applied to analyze and interpret the data. The results from the multivariate regression analysis revealed that the organization of working hours (β = 0.035) and shift work (β = 0.042) were significant predictors of EMS organization, explaining 1.9% of the variance (R2 = 0.019). Furthermore, shift work (β = -0.045) and working hours (β = -0.037) accounted for 2.0% of the variance in the number of EMS points performed (R2 = 0.020). Also, the availability of ambulance vehicles (β = 0.075) and financial resources (β = 0.033) explained 4.1% of the variance in mass casualty preparedness (R2 = 0.041). When it comes to service area coverage, the regression results suggest that none of the predictors were statistically significant. Based on Pearson's correlation results, there is a statistically significant correlation between the EMS organization and several key variables such as the number of EMS doctors (p = 0.000), emergency medicine specialists (p = 0.000), etc. Moreover, the Chi-square test results reveal statistically significant correlations between EMS organization and how EMS activities are conducted (p = 0.001), the number of activity locations (p = 0.005), and the structure of working hours (p = 0.001). Additionally, the results underscore the necessity for increased financial support, standardized protocols, and enhanced intersectoral collaboration to strengthen Serbia's EMRS and improve overall disaster response effectiveness. Based on these findings, a clear roadmap is provided for policymakers, healthcare administrators, and EMS personnel to prioritize strategic interventions and build a robust emergency medical response system.

Methods of Using a Manual Defibrillator during Simultaneous Cardiac Arrest in Two Patients-Analysis of the Actions of Emergency Medical Response Teams during the Championships in Emergency Medicine.

Background/Objectives: Conducting advanced resuscitation requires medical personnel to carry out appropriately coordinated actions. Certain difficulties arise when it becomes necessary to conduct cardiopulmonary resuscitation (CPR) on two patients at the same time. The aim of this paper was to assess the actions of teams participating in emergency medicine championships in tasks related to simultaneous cardiac arrests in two patients. Methods: The study was conducted on the basis of an analysis of assessment cards for tasks carried out during the 'International Winter Championships in Emergency Medicine'. Three-person medical response teams (MRTs), with the support of two people, had the task of conducting advanced resuscitation on an adult and child simultaneously. The tasks were prepared and developed by European Resuscitation Council (ERC) instructors. Results: The study showed that teams used four methods of checking heart rhythm and performing defibrillation during CPR-using paddles only, using paddles and self-adhesive electrodes, using paddles and a three-lead ECG and using two pairs of self-adhesive electrodes. Teams performing cardiopulmonary resuscitation using paddles and a three-lead ECG performed significantly more actions incorrectly than other teams-in part due to the fact that they incorrectly interpreted which patient's heart rhythm was displayed on the defibrillator screen. The effectiveness of the remaining methods was similar for most of the actions. The CPR method using two pairs of electrodes enabled personal safety to be maintained to the significantly highest percentage during defibrillation. Conclusions: The study demonstrated that the need to conduct CPR on two patients at the same time, irrespective of the method used, caused MRT members considerable difficulties in correctly conducting some of the actions. The method of assessing heart rhythm using paddles and a three-lead ECG should not be used. The study showed that the optimal method of CPR in use appears to be the method using two pairs of adhesive electrodes-it provided, among other things, the significantly highest percentage of safely conducted defibrillation.

Enhancing the Chain of Survival: The Role of Smartphone Applications in Cardiopulmonary Resuscitation.

This review explores the role of smartphone applications in providing real-time guidance for cardiopulmonary resuscitation (CPR) practices and highlights their potential to improve CPR quality among laypersons. A narrative literature review was conducted on the effectiveness of mobile CPR applications for smartphones. Studies published between 2014 and 2024 were included to ensure that new technological advances were examined. Our findings revealed that guided CPR applications significantly improve most critical parameters for efficacious resuscitation. Application users demonstrated that they achieved performance comparable to or even better than CPR-certified individuals. However, these tools have limitations, mostly related to familiarity, which may result in a delay in activating the application and, therefore, in initiating CPR. While smartphone applications are promising tools for enhancing bystander CPR, their integration into emergency medical response requires careful consideration. To fully take advantage of these applications, they should be incorporated into public health campaigns and standard CPR training. This would be even more successful if the application's functionality were standardized across different regions. Our research indicates that a combination of education and technology will likely play a major role in CPR training in the future, improving the efficacy and accessibility of life-saving measures. Smartphone applications could greatly improve the chain of survival in out-of-hospital cardiac arrest (OHCA) events. The design and accessibility of these applications as well as the integration of these applications with current emergency response frameworks should be the main areas of future research.

Quality and safety in prehospital airway management – retrospective analysis of 18,000 cases from an air rescue database in Germany

BackgroundPrehospital airway management remains crucial with regard to the quality and safety of emergency medical service (EMS) systems worldwide. In 2007, the benchmark study by Timmermann et al. hit the German EMS community hard by revealing a significant rate of undetected oesophageal intubations leading to an often-fatal outcome. Since then, much attention has been given to guideline development and training. This study evaluated the incidence and special circumstances of tube misplacement as an adverse peri-intubation event from a Helicopter Emergency Medical Services perspective.MethodsThis was a retrospective analysis of a German helicopter-based EMS database from January 1, 2012, to December 31, 2020. All registered patients were included in the primary analysis. The results were analysed using SPSS 27.0.1.0.ResultsOut of 227,459 emergency medical responses overall, a total of 18,087 (8.0%) involved invasive airway management. In 8141 (45.0%) of these patients, airway management devices were used by ground-based EMS staff, with an intubation rate of 96.6% (n = 7861), and alternative airways were used in 3.2% (n = 285). Overall, the rate of endotracheal intubation success was 94.7%, while adverse events in the form of tube misplacement were present in 5.3%, with a 1.2% rate of undetected oesophageal intubation. Overall tube misplacement and undetected oesophageal intubation occurred more often after intubation was carried out by paramedics (10.4% and 3.6%, respectively). In view of special circumstances, those errors occurred more often in the presence of trauma or cardiopulmonary resuscitation, with rates of 5.6% and 6.4%, respectively. Difficult airways with a Cormack 4 status were present in 2.1% (n = 213) of HEMS patients, accompanied by three or more intubation attempts in 5.2% (n = 11).ConclusionsPrehospital airway management success has improved significantly in recent years. However, adverse peri-intubation events such as undetected oesophageal intubation remain a persistent threat to patient safety.Trial registrationThe study was registered in the German Register for Clinical Studies (number DRKS00028068).

Transport of Patients With High-Consequence Infectious Diseases: Development of European Capacity in Norway.

Infection of Western aid workers with Ebola virus disease during the 2014-2016 West African outbreak demonstrated the need for medical evacuation to high-level isolation units in Europe and the United States. In Norway, an ad hoc preparedness team was established for aeromedical evacuation in case of need. In October 2014, this team transported an infected aid worker from the military section of Oslo Airport to Oslo University Hospital. To maintain and strengthen the capacity for domestic ambulance transport on the ground and in the air, the Norwegian Medical Emergency Response Team for High Consequence Infectious Diseases (in Norway known as "Nasjonalt medisinsk utrykningsteam for høyrisikosmitte"), or NORTH, was established as a permanent service in 2017. Recognizing the expertise of this domestic team, Norway was subsequently entrusted with the task of enhancing the European aeromedical transport capacity for high-consequence infectious diseases and establishing the Norwegian rescEU Jet Air Ambulance for Transport of Highly Infectious Patients, or NOJAHIP, in 2022. In this case study, we present experiences and lessons learned from these 2 services and discuss how they can be further developed.

Clinical trauma severity of indoor and outdoor injurious falls requiring emergency medical service response

BackgroundInjurious falls represent a significant public health burden. Research and policies have primarily focused on falls occurring indoors despite evidence that outdoor falls account for 47–58% of all falls requiring some medical attention. This study described the clinical trauma severity of indoor versus outdoor injurious falls requiring Emergency Medical Services (EMS) response.MethodsUsing the 2019 National Emergency Medical Services Information System (NEMSIS) dataset, we identified the location of patients injured from falls that required EMS response. We classified injury severity using (1) the Revised Trauma Score for Triage (T-RTS): ≤ 11 indicated the need for transport to a Trauma Center; (2) Glasgow Coma Scale (GCS): ≤ 8 and 9–12 indicated severe and moderate neurologic injury; and (3) patient clinical acuity by EMS: Dead, Critical, Emergent, Low.ResultsOf 1,854,909 encounters for patients with injurious falls, the vast majority occurred indoors (n = 1,596,860) compared to outdoors (n = 152,994). For patients who fell indoors vs outdoors on streets or sidewalks, the proportions were comparable for moderate or severe GCS scores (3.0% vs 3.9%), T-RTS scores indicating need for transport to a Trauma Center (5.2% vs 5.9%) and EMS acuity rated as Emergent or Critical (27.7% vs 27.1%). Injurious falls were more severe among male patients compared to females and males injured by falling on streets or sidewalks had higher percentages for moderate or severe GCS scores (5.2% vs 1.9%) and T-RTS scores indicating the need for transport to a Trauma Center (7.3% vs 3.9%) compared to falling indoors. Young and middle-aged patients who fell on streets or sidewalks had higher proportions for a T-RTS score indicating the need for Trauma Center care compared to those in this subgroup who fell indoors. Yet older patients injured by falling indoors were more likely to have a T-RTS score indicating the need for transport to a Trauma Center than older patients who fell on streets or sidewalks.ConclusionsThere was a similar proportion of patients with severe injurious falls that occurred indoors and outdoors on streets or sidewalks. These findings suggest the need to determine outdoor environmental risks for outdoor falls to support location-specific interventions.

Blood far forward: A cross-sectional analysis of prehospital transfusion practices in the Canadian Armed Forces

BackgroundCanadian Armed Forces (CAF) operate in environments that challenge patient care, especially trauma. Military personnel often find themselves in remote settings without conventional healthcare facilities. Treating traumatic injuries, particularly hemorrhagic shock, often necessitates prehospital blood transfusion. This study aims to present an overview of the current CAF prehospital transfusion practices. Furthermore, the study compared current and developing protocols against expert-recommended guidelines. MethodsA cross-sectional survey design was employed to describe and compare CAF prehospital blood transfusion practices and protocols against expert recommendations. Topics included protocols, equipment, and procedures. An online survey targeted medical leadership and providers within CAF, with data collected from August 15 to December 15, 2023. Results were summarized descriptively. This study received approval from the Unity Health Toronto Research Ethics Board (REB 23–087). ResultsUnits and teams with prehospital blood transfusion capabilities were contacted, achieving a 100 % response rate. Within CAF, Canadian Special Operations Forces Command (CANSOFCOM), Mobile Surgical Resuscitation Team (MSRT), and Canadian Medical Emergency Response Team (CMERT) possess these capabilities, established between 2013 and 2018. These programs are crucial for military operations. CAF has access to standard blood components, cold Leuko-Reduced Whole Blood (LrWB), and factor concentrates from Canadian Blood Services (CBS), available for both domestic and international missions given adequate planning and favorable conditions. Key findings indicate high adherence to recommended practices, some variability in the transfusion process, and potential benefits of standardizing prehospital transfusion practices. ConclusionsThis study provided insights into CAF's implementation of prehospital transfusion practices, highlighting high adherence to national expert recommendations and the importance of structured protocols in military prehospital trauma management. Implications of key findingsCAF's approach and adoption of prehospital transfusion protocols lay a strong foundation for managing trauma patients in remote settings and for expanding prehospital transfusion capabilities across CFHS deployed assets. Further research is needed to advance military trauma care by adapting prehospital blood transfusion to dynamic tactical landscapes and evolving technologies.

Cardiac Arrest and Cardiopulmonary Resuscitation Outcome Reports: 2024 Update of the Utstein Out-of-Hospital Cardiac Arrest Registry Template.

The Utstein Out-of-Hospital Cardiac Arrest Resuscitation Registry Template, introduced in 1991 and updated in 2004 and 2015, standardizes data collection to enable research, evaluation, and comparisons of systems of care. The impetus for the current update stemmed from significant advances in the field and insights from registry development and regional comparisons. This 2024 update involved representatives of the International Liaison Committee on Resuscitation and used a modified Delphi process. Every 2015 Utstein data element was reviewed for relevance, priority (core or supplemental), and improvement. New variables were proposed and refined. All changes were voted on for inclusion. The 2015 domains-system, dispatch, patient, process, and outcomes-were retained. Further clarity is provided for the definitions of out-of-hospital cardiac arrest attended resuscitation and attempted resuscitation. Changes reflect advancements in dispatch, early response systems, and resuscitation care, as well as the importance of prehospital outcomes. Time intervals such as emergency medical service response time now emphasize precise reporting of the times used. New flowcharts aid the reporting of system effectiveness for patients with an attempted resuscitation and system efficacy for the Utstein comparator group. Recognizing the varying capacities of emergency systems globally, the writing group provided a minimal dataset for settings with developing emergency medical systems. Supplementary variables are considered useful for research purposes. These revisions aim to elevate data collection and reporting transparency by registries and researchers and to advance international comparisons and collaborations. The overarching objective remains the improvement of outcomes for patients with out-of-hospital cardiac arrest.

Short Survey on Cardiopulmonary Resuscitation and Automated External Defibrillator Training in Rural British Columbia Schools: Preliminary Findings and Hypothesis-Generating Insights

BackgroundBritish Columbia (BC) faces more than 7000 out-of-hospital cardiac arrests annually, which disproportionately affect rural areas, owing to their slower emergency medical service response and limited specialized care. Despite the known benefits of automated external defibrillator (AED) access and cardiopulmonary resuscitation (CPR) training, their status in rural BC schools is poorly documented. MethodsWe used an online survey of principals and vice-principals of rural schools in BC. The survey assessed AED accessibility, prevalence of CPR and AED training, and obstacles to implementing such training. Questions covered school demographics, AED installation, and CPR and/or AED training for staff and students. ResultsWe recruited 23 elementary schools (kindergarten-grade 7; 46%), 6 middle schools (grades 6-8; 12%), and 21 high schools (grades 8- 12; 42%). A total of 72% (36 of 50) had at least one AED installed; 46% required staff CPR training; and 24% provided student CPR training. Significant gaps in training were noted for elementary and middle school students, compared to the training for high schools (P < 0.05). ConclusionsDisparities in AED and CPR training across rural schools in BC exist, highlighting a need for policy improvements and innovative solutions to enhance first-aid education. Barriers to implementing CPR and AED training included lack of funding, curricular priority, time constraints, and limited resources. Despite a 10.3% response rate, this study reveals significant disparities in AED and CPR training across school levels in rural BC, underscoring the need for targeted policies and educational strategies to enhance emergency preparedness and improve cardiac arrest outcomes in underserved areas.

Increasing cost-effectiveness of AEDs using algorithms to optimise location

ObjectivesVolunteer responder systems (VRSs) aim to decrease time to defibrillation by dispatching trained volunteers to automated external defibrillators (AEDs) and out-of-hospital cardiac arrest (OHCA) victims. AEDs are often underutilized due to poor placement. This study provides a cost-effectiveness analysis of adding AEDs at strategic locations to maximize quality-adjusted life years (QALYs). MethodsWe simulated combined volunteer, police, firefighter, and emergency medical service response scenarios to OHCAs, and applied our methods to a case study of Amsterdam, the Netherlands. We compared the competing strategies of placing additional AEDs, using steps of 40 extra AEDs (0, 40, …, 1480), in addition to the existing 369 AEDs. Incremental cost-effectiveness ratios (ICERs) were calculated for each increase in additional AEDs, from a societal perspective. The effect of AED connection and time to connection on survival to hospital admission and neurological outcome at discharge was estimated using logistic regression, using OHCA data from Amsterdam from 2006 to 2018. Other model inputs were obtained from literature. ResultsPurchasing up to 1120 additional AEDs (ICER €75,669/QALY) was cost-effective at a willingness-to-pay threshold of €80,000/QALY, when positioned strategically. Compared to current practice, adding 1120 AEDs resulted in a gain of 0.111 QALYs (95% CI 0.110–0.112) at an increased cost of €3792 per OHCA (95% CI €3778-€3807). Health benefits per AED diminished as more AEDs were added. ConclusionsOur study identified cost-effective strategies to position AEDs at strategic locations in a VRS. The case study findings advocate for a substantial increase in the number of AEDs in Amsterdam.

Systematic Review on the Worldwide Disparities in the Frequency and Results of Emergency Medical Services (EMS) and Response to Out-of-Hospital Cardiac Arrest (OHCA).

This systematic analysis aimed to analyze the key patterns and tendencies regarding bystander interventions, emergency medical service (EMS) systems, dispatcher support, regional and temporal differences, and the influence of national efforts on survival rates in out-of-hospital cardiac arrest (OHCA). The studies published between 2010 and 2024 examining outcomes of OHCA, interventions by bystanders, and variables linked to OHCA were included in this research. The inclusion process was done under Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), where publications (n = 24) from various geographical locations, including a wide range of research methodologies, were included for this research. The thematic analysis used for the data analysis shows that bystander cardiopulmonary resuscitation (CPR) enhances the chances of survival. The effectiveness of the EMS system, the assistance offered by dispatchers, and the inclusion of doctors in ambulance services are essential components in the management of OHCA. Regional and temporal variations highlight disparities in resuscitation protocols, emphasizing the need for adaptable approaches. Observations from statewide endeavors emphasize the impact of these activities in fostering a culture of prompt bystander intervention. This systematic review presents a comprehensive analysis of research conducted globally, providing a thorough insight into the variables that influence survival rates in instances of OHCA. The review recognizes the importance of bystander CPR and effective EMS services, while also bringing novel perspectives, such as gender disparities and geographical variations that contribute to the existing body of research. Despite possible variances in the studies and biases, the findings underscore the need for tailored therapies and ongoing research to optimize strategies for controlling OHCA and improving survival rates.

Evaluating communication capability across diverse groups for disaster medicine: A time-tracking method for functional exercises

Recent experiences in disaster medicine in Japan have shown the importance of preventing post-disaster health deterioration among citizens during the evacuation and recovery phases. The effective involvement of various medical, social welfare, and nursing organizations is necessary to mitigate these health problems. This study explored the effectiveness of a time-tracking evaluation method for functional exercises in analyzing the communication and joint task-processing capabilities of various medical and social welfare organizations in response to a citywide heavy-rain disaster. Each exercise inject was analyzed in advance to create a task-processing chain according to the emergency medical response plan. The actions of the exercise players were then compared with the expected tasks in the processing chain. The exercise created overload for some player groups. The completion rates and average execution times of the tasks were compared across task types and player groups, indicating the potential weaknesses of the current emergency operation plan. Responses of local medical associations to similar exercise injects were compared to analyze the range of diversity in responses and the merits of past exercise participation. Although the results of this time-tracking evaluation need to be carefully interpreted by combining the results regarding the quality of players' exercise actions, this method provides a new perspective for evaluating emergency operation plans through functional exercises.

Adaptive Ambulance Management System

The ability to quickly and accurately retrieve information is essential for emergency medical response. This project integrates biometric technology and web applications to offer a comprehensive solution for improving emergency medical services. Our approach starts with the use of a fingerprint scanner, which records information on patients and guardians and links it to distinctive fingerprints. A Node MCU processes and stores this data, making it possible to quickly and securely identify patients in urgent situations. The Node MCU displays patient information on an LCD panel as soon as they provide their fingerprint. Both ambulance drivers and hospital administration have access to a user-friendly web application simultaneously. The software gives users access to a database of nearby hospitals that is divided into public and private facilities. Soon, the selected hospital will be informed about the patient condition and able to make the treatment arrangements earlier. The patient's preferences and the resources at their disposal can help ambulance crew make wise selections. Ambulance crew have two selection buttons, one is government hospital selection button and another is private hospital selection button. By reducing response times, this function improves patient care. In order to safeguard sensitive patient data, the project places a strong emphasis on data security and privacy. Our goal is to maximize emergency medical response through this integrated system, ensuring that patients receive prompt and efficient care when it counts.
