Background: Telehealth has become increasingly essential in healthcare provision, also in the Prehospital Emergency Medical Services (EMS), where live video is implemented as a supplemental tool to assess and triage medical emergency calls. So far, using video for emergency calls seems beneficial for patient assessment and dispatcher-assisted first aid. However, the EMS dispatchers' experiences with and perceptions of using video during emergency calls are largely unexplored. Methods: In 2023, a nationwide survey study was conducted in Denmark, which is covered by five Emergency Medical Dispatch Centers. All Danish EMS dispatchers were invited to participate in the study. The survey explored the dispatchers' experience with using video during emergency calls, the perception of their own video use, and the process of implementing video as a new tool in their working procedure. Main questions were answered on a scale from 1 to 7, where higher scores indicate more agreement. Results: Of the 183 EMS dispatchers employed during the study period, 78% completed the survey. They found video easy to use (median = 7) and found video supportive in guidance and dispatch when the patient's problem was unclear (median = 7), but did not find video suitable for all emergency calls and expressed that complications with the technology was a barrier for using video. The EMS dispatchers were least likely to agree that they choose not to use video due to the risk of being emotionally affected by what they might see (median = 1). When dividing the sample based on EMS dispatcher's gender, age, seniority, and educational background, generally few differences between groups were found. Conclusions: Live video during emergency calls is generally experienced as a useful supplemental tool by EMS dispatchers in Denmark, and the greatest self-perceived barriers for using video were not finding video suitable for all situations and the technology.

Objectives: Emergency Medical Communication Centers (EMCC) have a key role in the prehospital chain-of-stroke-survival by recognizing stroke patients and reducing prehospital delay. However, studies on EMCC stroke recognition report both substantial undertriage and overtriage. Since mis-triage at the EMCC challenges the whole chain-of-stroke-survival, by occupying limited resources for non-stroke patients or failing to recognize the true stroke patients, there is a need to achieve a more comprehensive understanding of the dispatchers' routines and experiences. The aim of this study was to explore factors affecting EMCC dispatcher's decision-making in stroke calls. Materials and methods: A qualitative exploratory study, based on individual semi-structured interviews of 15 medical dispatchers from EMCC Oslo, Norway. Interviews were conducted during August and October 2022 and analyzed using the principles of thematic analysis. Results: We identified four themes: [1] Pronounced stroke symptoms are easy to identify [2]. Non-specific neurological symptoms raise suspicion of acute stroke but are difficult to differentiate from other medical conditions [3]. Consistent use of the Criteria Based Dispatch (CBD) protocol may increase EMCC overtriage [4]. Contextual conditions at EMCC can affect dispatchers' decision-making process and the ability for experiential learning. Conclusions: Medical dispatchers at the EMCC perceive vague and non-specific stroke symptoms, such as dizziness, confusion or altered behaviour, challenging to differentiate from symptoms of other less time-critical medical conditions. They also perceive the current CBD protocol in use as less supportive in assessing such symptoms. High workload and strict EMCC response time interval requirements hinder the gathering of essential patient information and the ability to seek guidance in cases of doubt, potentially exacerbating both EMCC undertriage and overtriage. The absence of feedback loops and other strategies for experiential learning in the EMCC hampers the medical dispatcher's ability to evaluate their own assessments and improve dispatch accuracy.

- Abstract
Background: The global strain on Emergency Medical Services (EMS) is reflected in the increasing number of emergency ambulance dispatches. Shorter EMS response times have demonstrated some effect on very specific and rare conditions. It is unknown if the increased number of ambulance dispatches compromises response times. This study aimed to describe trends in emergency ambulance dispatches and response times from 2013 to 2022 in Region Zealand, Denmark. Additionally, it aimed to outline the demographic profile of emergency ambulance patients, including age and comorbidities. Methods: Using administrative data from the Region Zealand emergency medical dispatch center, a register-based study spanning from January 1, 2013, to December 31, 2022, was conducted. Data were linked with nationwide registries and priority A (emergency), or B (urgent) ambulance dispatches were included. Trends were examined overall and stratified by catchment areas corresponding to the hospitals with emergency departments in the region. Poisson and ordinal logistic regressions were used to analyze data. Results: The study encompassed 678,789 emergency ambulance dispatches, with 55.0% priority A and 45.0% priority B. Among these, 667,788 had a valid personal identification number allowing for further analysis. Within the study population, females comprised 48.5%, while 49.1% of patients were 65 years or more. Overall, 47.5% of patients had no comorbidities, while 7.7% and 44.8% had mild and severe comorbidities, respectively. Emergency ambulance dispatches increased from 56,867 in 2013 to 81,080 in 2022 (143%). Correspondingly, the dispatch incidence rate per 1,000 residents per year increased from 69.2 to 95.5. Stratification by catchment areas revealed significant disparities. The median response time for priority A dispatches increased from 7 min:14 s in 2013 to 8 min:20 s in 2022 and for priority B dispatches from 12 min:23 s to 15 min:6 s. Conclusions: From 2013 to 2022, emergency ambulance dispatches both priorities A and B increased in absolute numbers and per 1000 residents per year. Ambulance response times also increased for both priorities during the study period. The study shows regional disparities regarding to the rate of emergency ambulance dispatches and response times indicating challenges in resource distribution in the future for maintaining emergency care standards.

Abstract Background In modern emergency medical services (EMS), ambulances increasingly focus on examining and treating the patient at the scene. This has led to increased levels of non-conveyance. In Finland, for instance, approximately 40% of EMS dispatches end up in non-conveyance. As EMS systems evolve, the proportion of non-conveyance could serve as a cost-effective measure to assess the quality of the dispatch criteria, if a link to the performance of urgency assessment would be established. The purpose of this study was to investigate whether the proportion of non-conveyance is associated with the test performance levels of the urgency assessment. This investigation was done separately within each dispatch category. Methods A retrospective evaluation of the data was conducted on all EMS dispatches in the Pirkanmaa Hospital District from 1 August 2021 through 31 August 2021. There were a total of 7,245 EMS dispatches during the study period of which 829 were excluded. This study was conducted by comparing the existing test performance levels (sensitivity, specificity and under- or overestimation) of the emergency response centre’s urgency assessment with the non-conveyance rate (%) of each dispatch category. The relationships between the variables were measured using Spearman’s rank correlation coefficient. Results The proportion of over-triage was the only urgency assessment’s test performance variable that had a statistically significant correlation with the proportion of non-conveyance (r = 0.568; p = 0.003). Other test performance variables of the urgency assessment had no or little correlation to the proportion of non-conveyance. Of the 6,416 EMS dispatches in the study period, 42% (2,672) resulted in non-conveyance of the patient. In nine dispatch categories, at least half (51–69%) of the dispatches ended in non-conveyance. Conclusions Based on this study, it seems that the percentage of non-conveyance in the dispatch category could be used, with certain limitations, to assess the proportion of over-triage in the dispatch category. The method is particularly applicable in scenarios where the dispatch criteria have undergone modifications and there is a need to monitor the effect of the changes on the level of over-triage.

Objective: The ambulance service in Victoria, Australia implemented a revised clinical response model (CRM) in 2016 which was designed to increase the diversion of low‐acuity Triple Zero (000) calls to secondary telephone triage and reduce emergency ambulance dispatches. The present study evaluates the influence of the revised CRM on emergency ambulance response times and ED presentations. Methods: A retrospective study of emergency calls for ambulance between 1 January 2015 and 31 December 2018. Ambulance data were linked with ED presentations occurring up to 48 h after contact. Interrupted time series analyses were used to evaluate the impact of the revised CRM. Results: A total of 2 365 529 calls were included. The proportion allocated a Code 1 (time‐critical, lights/sirens) dispatch decreased from 56.6 to 41.0% after implementation of the revised CRM. The proportion of calls not receiving an emergency ambulance increased from 10.4 to 19.6%. Interrupted time series analyses demonstrated an improvement in Code 1 cases attended within 15 min (Key Performance Indicator). However, for patients with out‐of‐hospital cardiac arrest or requiring lights and sirens transport to hospital, there was no improvement in response time performance. By the end of the study period, there was also no difference in the proportion of callers presenting to ED when compared with the estimated proportion assuming the revised CRM had not been implemented. Conclusion: The revised CRM was associated with improved Code 1 response time performance. However, there was no improvement in response times for high acuity patients, and no change in the proportion of callers presenting to ED. [ABSTRACT FROM AUTHOR]

Background and Objectives: Out-of-hospital cardiac arrest (OHCA) and survival is a pressing matter all around the world. Despite years of research and great strides and advancements, survival remains alarmingly low. The aim of this study was to measure the survival and characteristics of patients having an OHCA in Slovenia, with an in-depth look at how the bystanders affect the return of spontaneous circulation (ROSC) and survival of OHCA. Materials and Methods: In this observational cross-sectional prospective study, we enrolled patients between 1 September 2022 and 30 November 2022, with a follow-up period of 1 month. All OHCAs attended by the emergency medical services were included. Data were collected and analyzed according to the Utstein 2015 reporting template. Independent predictors of ROSC and 30-day survival or survival were explored using ridge regression. Results: ROSC was achieved in 41% of cases where resuscitation was attempted. The overall 30-day survival rate where resuscitation was attempted was 14%. In 13% of all cases where resuscitation was attempted, patients had a favorable neurological outcome. Using our prediction model, we found that defibrillation under 20 min and ventricular fibrillation as an initial rhythm improves survival, whilst no defibrillation and bystander full cardiopulmonary resuscitation negatively predicted survival. Conclusions: Slovenia has OHCA 30-day survival comparable to the rest of the European Union. The favorable neurological outcome is high. Our data show that bystanders do not significantly improve survival. This represents an untapped potential of general public education in cardiopulmonary resuscitation and automatic external defibrillator use. Following good practices from abroad and improving layperson CPR knowledge could further improve OHCA survival. [ABSTRACT FROM AUTHOR]

Abstract Background Timely dispatch of appropriate emergency medical services (EMS) resources to the scene of medical incidents, and/or provision of treatment at the scene by bystanders and medical emergency lay callers (referred to as ‘callers’ in this review) can improve patient outcomes. Currently, in dispatch systems worldwide, prioritisation of dispatch relies mostly on verbal telephone information from callers, but advances in mobile phone technology provide means for sharing video footage. This scoping review aimed to map and identify current uses, opportunities, and challenges for using video livestreaming from callers’ smartphones to emergency medical dispatch centres. Methods A scoping review of relevant published literature between 2007 and 2023 in the English language, searched within MEDLINE; CINAHL and PsycINFO, was descriptively synthesised, adhering to the PRISMA extension for scoping reviews. Results Twenty-four articles remained from the initial search of 1,565 articles. Most studies were simulation-based and focused on emergency medical dispatchers’ (referred to as ‘dispatcher/s’ in this review) assisted video cardiopulmonary resuscitation (CPR), predominantly concerned with measuring how video impacts CPR performance. Nine studies were based on real-life practice. Few studies specifically explored experiences of dispatchers or callers. Only three articles explored the impact that using video had on the dispatch of resources. Opportunities offered by video livestreaming included it being: perceived to be useful; easy to use; reassuring for both dispatchers and callers; and informing dispatcher decision-making. Challenges included the potential emotional impact for dispatchers and callers. There were also concerns about potential misuse of video, although there was no evidence that this was occurring. Evidence suggests a need for appropriate training of dispatchers and video-specific dispatch protocols. Conclusion Research is sparse in the context of video livestreaming. Few studies have focussed on the use of video livestreaming outside CPR provision, such as for trauma incidents, which are by their nature time-critical where visual information may offer significant benefit. Further investigation into acceptability and experience of the use of video livestreaming is warranted, to understand the potential psychological impact on dispatchers and callers.

Background: The Chain of Survival identifies the importance of early recognition of patients who are at imminent risk of out-of-hospital cardiac arrest. This research investigated the interaction between callers and call-takers during calls to the Emergency Medical Service; it specifically focussed on patients who were alive at the initiation of the EMS call, but who subsequently deteriorated into out-of-hospital cardiac arrest during the prehospital phase of care (i.e., before arrival at hospital). Methods: Conversation-analytic methods were used to examine the call openings of 38 Emergency Medical Service calls for patients who were at imminent risk of out-of-hospital cardiac arrest. Call openings centred on pre-triage questions designed to rapidly identify patients who are either in out-of-hospital cardiac arrest, or who are at imminent risk of out-of-hospital cardiac arrest. Results: Emergency Medical Service call openings did not facilitate efficient and accurate triage, thus delaying the identification of critically unwell patients by call-takers. In 50% of call openings, the caller wanted to give the reason for the call during the pre-triage questions. The caller and call-takers orientate to different agendas causing delays to call progression and risking information loss that impacts on effective call triage. Conclusions: The design of the Emergency Medical Service call opening can cause interactional trouble, thus impacting on call progression and risking critical information loss. Modifications to the Emergency Medical Service call opening to quickly align the caller and call-taker, communications training for call-takers and public education may support early identification of patients at imminent risk of out-of-hospital cardiac arrest.

Abstract Purpose Emergency Medical Services (EMS) in Alberta are facing critical challenges. This qualitative study aims to describe and understand the frontline perspective regarding system level issues and propose provider-informed policy recommendations. Methods 19 semi-structured one-on- one interviews were conducted with Primary or Advanced Care Paramedics (PCP/ACP) across Alberta. Participants were asked to share their perspectives, experiences and recommendations in relation to EMS response times and the working environment. Interviews were analyzed using thematic analysis to identify themes and subthemes. Results Two core themes were identified as areas of concern: poor response times and the EMS working environment, which each influence and impact the other. Within response times, paramedics highlighted specific difficulties with ED offloading, a lack of resources, low-acuity calls, and rural challenges. In terms of the EMS working environment, four subthemes were apparent including attrition, unhealthy culture, organizational barriers and the need for paramedic empowerment. Providers made many recommendations including creating and expanding emergency mobile integrated health (MIH) branches, sharing 811 and 911 responses, and enforcing ED target offload times amongst other suggestions. Conclusions While response times are a key and highly visible problem, there are many critical factors like the EMS working environment that degrade patient care and cause concern amongst frontline practitioners. Multifaceted policy changes are to be explored to reduce disfunction within EMS services, enhance the well-being of the workforce and deliver improved patient care. Specific EMS-oriented policies are important for moving forward to reduce transfers to EDs, but the broader health system which is over capacity is causing downstream effects into EMS must be addressed by government and health administrators.

Abstract Objectives In this study we aimed to explore EMCC triage of suspected and confirmed stroke patients to gain more knowledge about the initial phase of the acute stroke response chain. Accurate dispatch at the Emergency Medical Communication Center (EMCC) is crucial for optimal resource utilization in the prehospital service, and early identification of acute stroke is known to improve patient outcome. Materials and methods We conducted a descriptive retrospective study based on data from the Emergency Department and EMCC records at a comprehensive stroke center in Oslo, Norway, during a six-month period (2019–2020). Patients dispatched with EMCC stroke criteria and/or discharged with a stroke diagnosis were included. We identified EMCC true positive, false positive and false negative stroke patients and estimated EMCC stroke sensitivity and positive predictive value (PPV). Furthermore, we analyzed prehospital time intervals and identified patient destinations to gain knowledge on ambulance services assessments. Results We included 1298 patients. EMCC stroke sensitivity was 77% (95% CI: 72 − 82%), and PPV was 16% (95% CI: 14 − 18%). EMCC false negative stroke patients experienced an increased median prehospital delay of 11 min (p

Monkeypox 2022 exhibits unprecedented human-to-human transmission and presents with different clinical features than those observed in prior outbreaks. Previously endemic only to West and Central Africa, the monkeypox virus spread rapidly world-wide following confirmation of a case in the United Kingdom on May 7, 2022 of an individual that had traveled to Nigeria. Detection of cases with no travel history confirms on-going community spread. Emergency Medical Services (EMS) professionals will likely encounter patients suspected or confirmed to have monkeypox, previously a rare disease and therefore unfamiliar to most clinicians. Consequently, it is critical for EMS medical directors to immediately implement policies and procedures for EMS teams - including emergency medical dispatchers - to identify potential monkeypox cases. These must include direction on actions EMS professionals should take to protect themselves and others from virus transmission. Monkeypox 2022 may manifest more subtly than it has historically. Presentations include a subclinical prodrome and less dramatic skin lesions - potentially limited to genital or anal body regions - which can be easily confused with dermatologic manifestations of common sexually transmitted infections (STIs). While most readily spread by close contact with infectious skin lesions on a patient, it is also transmissible from fomites, such as bed sheets. Additionally, droplet transmission can occur, and the virus can be spread by aerosolization under certain conditions. The long incubation period could have profound negative consequences on EMS staffing if clinicians are exposed to monkeypox. This report summarizes crucial information needed for EMS professionals to understand and manage the monkeypox 2022 outbreak. It presents an innovative Identify-Isolate-Inform (3I) Tool for use by EMS policymakers, educators, and clinicians on the frontlines who may encounter monkeypox patients. Patients are identified as potentially exposed or infected after an initial assessment of risk factors with associated signs and symptoms. Prehospital workers must immediately don personal protective equipment (PPE) and isolate infectious patients. Also, EMS professionals must report exposures to their agency infection control officer and alert health authorities for non-transported patients. Prehospital professionals play a crucial role in emerging and re-emerging infectious disease mitigation. The monkeypox 2022 3I Tool includes knowledge essential for all clinicians, plus specific information to guide critical actions in the prehospital environment.

Introduction: Following Mass Casualty Incidents (MCIs), the sudden surge in demand for essential services disrupts the balance between available and required resources. This study aimed to systematically identify and categorize existing systems employed for dispatching professional or lay rescuers during emergencies. Methods: Adhering to the PRISMA 2020 Checklist, the research scrutinized international databases (PubMed, Scopus, and Web of Science) using formulated search strategies. Additionally, a manual search was conducted on Google Scholar and prominent journals employing specific keywords. Original articles introducing systems for dispatching rescuers to incident sites were included. Results: Thirty-one of the 23051 initially identified documents were included for data extraction and quality assessment. The comprehensive analysis revealed twenty-two dispatch systems worldwide, contributing to life-saving efforts in emergencies. Additionally, an evaluation of the articles' quality using the Mixed Methods Appraisal Tool (MMAT) with five scores, indicated that more than two-thirds of the identified articles scored four or higher. Summarizing the data extracted from these systems, four distinct categories of recall system characteristics were identified: general, dispatcher, responder, and other features. Conclusion: Technology has the potential to revolutionize the delivery of healthcare services. This study highlights four key elements necessary for the development of dispatch systems that can effectively mobilize healthcare providers to the incident scene. These elements include general characteristics, dispatcher roles, responder requirements, and additional features, which equip researchers with the knowledge for designing effective systems to recall healthcare providers during MCI.

Abstract Background Use of bystander video livestreaming from scene to Emergency Medical Services (EMS) is becoming increasingly common to aid decision making about the resources required. Possible benefits include earlier, more appropriate dispatch and clinical and financial gains, but evidence is sparse. Methods A feasibility randomised controlled trial with an embedded process evaluation and exploratory economic evaluation where working shifts during six trial weeks were randomised 1:1 to use video livestreaming during eligible trauma incidents (using GoodSAM Instant-On-Scene) or standard care only. Pre-defined progression criteria were: (1) ≥ 70% callers (bystanders) with smartphones agreeing and able to activate live stream; (2) ≥ 50% requests to activate resulting in footage being viewed; (3) Helicopter Emergency Medical Services (HEMS) stand-down rate reducing by ≥ 10% as a result of live footage; (4) no evidence of psychological harm in callers or staff/dispatchers. Observational sub-studies included (i) an inner-city EMS who routinely use video livestreaming to explore acceptability in a diverse population; and (ii) staff wellbeing in an EMS not using video livestreaming for comparison to the trial site. Results Sixty-two shifts were randomised, including 240 incidents (132 control; 108 intervention). Livestreaming was successful in 53 incidents in the intervention arm. Patient recruitment (to determine appropriateness of dispatch), and caller recruitment (to measure potential harm) were low (58/269, 22% of patients; 4/244, 2% of callers). Two progression criteria were met: (1) 86% of callers with smartphones agreed and were able to activate livestreaming; (2) 85% of requests to activate livestreaming resulted in footage being obtained; and two were indeterminate due to insufficient data: (3) 2/6 (33%) HEMS stand down due to livestreaming; (4) no evidence of psychological harm from survey, observations or interviews, but insufficient survey data from callers or comparison EMS site to be confident. Language barriers and older age were reported in interviews as potential challenges to video livestreaming by dispatchers in the inner-city EMS. Conclusions Progression to a definitive RCT is supported by these findings. Bystander video livestreaming from scene is feasible to implement, acceptable to both 999 callers and dispatchers, and may aid dispatch decision-making. Further assessment of unintended consequences, benefits and harm is required. Trial registration. ISRCTN 11449333 (22 March 2022). https://www.isrctn.com/ISRCTN11449333

Abstract Background The Emergency Medical Communications Center (EMCC) is essential in emergencies and often represents the public’s first encounter with the healthcare system. Previous research has mainly focused on the dispatcher’s perspective. Therefore, there is a lack of insight into the callers’ perspectives, the attainment of which may contribute significantly to improving the quality of this vital public service. Most calls are now made from mobile phones, opening up novel approaches for obtaining caller feedback using tools such as short-message services (SMS). Thus, this study aims to obtain a better understanding of callers’ actual experiences and how they perceived their interaction with the EMCC. Methods A combination of quantitative and qualitative study methods was used. An SMS survey was sent to the mobile phone numbers of everyone who had contacted 113 during the last months. This was followed by 31 semi-structured interviews with people either satisfied or dissatisfied. Thematic analysis was used to investigate the interviews. Results We received 1680 (35%) responses to the SMS survey, sent to 4807 unique numbers. Most respondents (88%) were satisfied, evaluating their experience as 5 or 6 on a six-point scale, whereas 5% answered with 1 or 2. The interviews revealed that callers were in distress before calling 113. By actively listening and taking the caller seriously, and affirming that it was the right choice to call the emergency number, the EMCC make callers experience a feeling of help and satisfaction, regardless of whether an ambulance was dispatched to their location. If callers did not feel taken seriously or listened to, they were less satisfied. A negative experience may lead to a higher distress threshold and an adjusted strategy before the caller makes contact 113 next time. Callers with positive experiences expressed more trust in the healthcare systems. Conclusions For the callers, the most important was being taken seriously and listened to. Additionally, they welcomed that dispatchers express empathy and affirm that callers made the right choice to call EMCC, as this positively affects communication with callers. The 113 calls aimed to cooperate in finding a solution to the caller’s problem.

Out-of-Hospital Cardiac Arrest ,Emergency Medical Dispatch - Abstract
Current international guidelines and the associated "chain of survival" emphasise the recognition of critically unwell patients in the community followed by an efficient response in the hope of preventing out-of-hospital cardiac arrest, which occurs when the heart stops beating suddenly. This thesis investigates how Emergency Medical (ambulance) Services can improve their recognition and response to patients who are at imminent risk of out-of-hospital cardiac arrest to reduce mortality and improve outcomes. Four distinct studies were completed: a)Systematic mixed studies review; b)Retrospective observational study of Emergency Medical Services call triage and the outcome of patients at imminent risk of out-of-hospital cardiac arrest;c)Conversation analysis of the Emergency Medical Services call;d)Interviews with Emergency Operations Centre staff. This patient group is not well studied in the existing literature, with current research focusing on the recognition and response to individuals who have already suffered a cardiac arrest, even though people at imminent risk have a potentially better chance of survival. Emergency Medical Dispatcher management of the Emergency Medical Services call is critical in the identification of these high-risk patients. Data analysis showed that Emergency Medical Services respond less urgently to patients at imminent risk of out-of-hospital cardiac arrest in comparison to patients already in cardiac arrest at the time of the call, with a negative impact on patient outcomes. The Emergency Medical Services interaction can be inefficient, leading to lost information. Emergency Medical Dispatchers require enhanced education and clinical support, and opportunities to monitor deteriorating patients. Members of the public would benefit from education regarding the structure and process of the Emergency Medical Services call. This thesis describes distinct areas where improvements can be made, and further research undertaken, in the recognition and response to patients in the community who are at imminent risk of out-of-hospital cardiac arrest.

Background: The incidence of cardiovascular diseases, and with it out-of-hospital cardiac arrest (OHCA), is on the increase in low- to middle-income countries (LMICs), like South Africa. Interventions such as mass public cardiopulmonary resuscitation (CPR) training campaigns and public access defibrillators are expensive and out of reach for many LMICs. Telephone-assisted CPR (tCPR) is a cost-effective, scalable alternative. This study explored the barriers and facilitators to tCPR uptake in OHCA in a private South African emergency dispatch centre. Methods: This qualitative study applied inductive dominant content analysis to emergency call recordings of OHCA cases into a private emergency dispatch centre. Calls were analysed to the latent level to identify barriers and facilitators. Cases were sampled randomly, until data saturation. Results: Saturation occurred after the analysis of 25 recordings. A further three recordings were analysed to confirm saturation of the facilitators; yielding a final sample size of 28 calls. Overall, t-CPR was offered in 23 (82.1%) cases, but only initiated in 8 (34.8%) of these calls. Five barriers (“Poor Communication”; “Lack of Support”; “Caller Hesitance or Uncertainty;” “Emotionality”; and “Practical Barriers”) and three facilitators (“Caller Willingness”; “Support” and “CPR in Progress”) were extracted. Conclusion: Numerous barriers limit the initiation of tCPR in the South African private sector EMS. It is crucial to address these barriers and leverage the facilitators in order to improve tCPR uptake. This study highlights the importance of using specific language techniques and developing tailored tCPR algorithms to overcome these barriers, which is underpinned by standardised training of call-takers.

Artificial intelligence (AI)–based clinical decision support systems are gaining momentum by relying on a greater volume and variety of secondary use data. However, the uncertainty, variability, and biases in real-world data environments still pose significant challenges to the development of health AI, its routine clinical use, and its regulatory frameworks. Health AI should be resilient against real-world environments throughout its lifecycle, including the training and prediction phases and maintenance during production, and health AI regulations should evolve accordingly. Data quality issues, variability over time or across sites, information uncertainty, human-computer interaction, and fundamental rights assurance are among the most relevant challenges. If health AI is not designed resiliently with regard to these real-world data effects, potentially biased data-driven medical decisions can risk the safety and fundamental rights of millions of people. In this viewpoint, we review the challenges, requirements, and methods for resilient AI in health and provide a research framework to improve the trustworthiness of next-generation AI-based clinical decision support.

Abstract Background Helicopter Emergency Medical Services (HEMS) are a limited and expensive resource, and should be intelligently tasked. HEMS dispatch was identified as a key research priority in 2011, with a call to identify a ‘general set of criteria with the highest discriminating potential’. However, there have been no published data analyses in the past decade that specifically address this priority, and this priority has been reaffirmed in 2023. The objective of this study was to define the dispatch criteria available at the time of the initial emergency call with the greatest HEMS utility using a large, regional, multi-organizational dataset in the UK. Methods This retrospective observational study utilized dispatch data from a regional emergency medical service (EMS) and three HEMS organisations in the East of England, 2016–2019. In a logistic regression model, Advanced Medical Priority Dispatch System (AMPDS) codes with ≥ 50 HEMS dispatches in the study period were compared with the remainder to identify codes with high-levels of HEMS patient contact and HEMS-level intervention/drug/diagnostic (HLIDD). The primary outcome was to identify AMPDS codes with a > 10% HEMS dispatch rate of all EMS taskings that would result in 10–20 high-utility HEMS dispatches per 24-h period in the East of England. Data were analysed in R, and are reported as number (percentage); significance was p 10% HEMS dispatch of all EMS taskings) resulted in 17 taskings per 24-h period. This definition derived nine AMPDS codes with high HEMS utility. Conclusion We have identified nine ‘golden’ AMPDS codes, available at the time of initial emergency call, that are associated with high-levels of whole-system and HEMS utility in the East of England. We propose that UK EMS should consider immediate HEMS dispatch to these codes.

Introduction: There is little research on the triage of patients who are not yet in cardiac arrest when the emergency call is initiated, but who deteriorate and suffer a cardiac arrest during the prehospital phase of care. The aim of this study was to investigate Emergency Operation Centre staff views on ways to improve the early identification of patients who are at imminent risk of cardiac arrest, and the barriers to achieving this. Methods: A qualitative interview and focus group study was conducted in two large Emergency Medical Services in England, United Kingdom. Twelve semi-structured interviews and one focus group were completed with Emergency Operations Centre staff. Data were analysed using reflexive thematic analysis. Results: Three main themes were identified: The dispatch protocol and call-taker audit; Identifying and responding to deteriorating patients; Education, knowledge and skills. Barriers to recognising patients at imminent risk of cardiac arrest include a restrictive dispatch protocol, limited opportunity to monitor a patient, compliance auditing and inadequate education. Clinician support is not always optimal, and a lack of patient outcome feedback restricts dispatcher learning and development. Suggested remedies include improvements in training and education (call-takers and the public), software, clinical support and patient outcome feedback. Conclusions: Emergency Operation Centre staff identified a multitude of ways to improve the identification of patients who are at imminent risk of out-of-hospital cardiac arrest during the Emergency Medical Service call. Suggested areas for improvement include education, triage software, clinical support redesign and patient outcome feedback.

Background Time to treatment is critical for survival from sudden cardiac arrest. Every minute delay in defibrillation results in a 7% to 10% reduction in survival. This is particularly problematic in rural and remote regions, where emergency medical service response is prolonged and automated external defibrillators (AEDs) are often not available. Our primary objective was to examine the feasibility of a novel AED drone delivery method for rural and remote sudden cardiac arrest. A secondary objective was to compare response times between AED drone delivery and ambulance to mock sudden cardiac arrest resuscitations. Methods and Results We conducted 6 simulations in 2 rural communities in southern Ontario, Canada. In the first 2 simulations, the drone and ambulance were dispatched from the same paramedic base. In simulations 3 and 4, the drone and ambulance were dispatched from separate paramedic bases; and in simulations 5 and 6, the drone was dispatched from an optimized location. During each simulation, a mock call was placed to 911 and a single AED drone and an ambulance were simultaneously dispatched to a predetermined destination. On scene, trained first responders retrieved the AED from the drone and initiated resuscitative efforts on a mannequin until paramedics arrived. No difficulties were encountered during drone activation by dispatch, ascent, landing, or bystander retrieval of the AED from the drone. During simulations 1 and 2, the distance to the scene was 6.6 km. For simulations 3 and 4, the ambulance response distance increased to 8.8 km while drone remained at 6.6 km; and in simulations 5 and 6, the ambulance response distance was 20 km compared with 9 km for the drone. During each flight, the AED drone arrived on scene before the ambulance, between 1.8 and 8.0 minutes faster. Conclusions This study suggests AED drone delivery is feasible, with the potential for improvements in response time during simulated sudden cardiac arrest scenarios. Further research is required to determine the appropriate system configuration for AED drone delivery in an integrated emergency medical service system as well as optimal strategies to simplify bystander application of a drone-delivered AED.

Abstract Background Telephone-Cardiopulmonary Resuscitation (T-CPR) significantly increases rate of bystander resuscitation and improves patient outcomes after out-of-hospital cardiac arrest (OHCA). Nevertheless, securing correct execution of instructions remains a difficulty. ERC Guidelines 2021 recommend standardised instructions with continuous evaluation. Yet, there are no explicit recommendations on a standardised wording of T-CPR in the German language. We investigated, whether a modified wording regarding check for breathing in a German T-CPR protocol improved performance of T-CPR. Methods A simulation study with 48 OHCA scenarios was conducted. In a non-randomised trial study lay rescuers were instructed using the real-life-CPR protocol of the regional dispatch centre and as the intervention a modified T-CPR protocol, including specific check for breathing (head tilt-chin lift instructions). Resuscitation parameters were assessed with a manikin and video recordings. Results Check for breathing was performed by 64.3% (n = 14) of the lay rescuers with original wording and by 92.6% (n = 27) in the group with modified wording (p = 0.035). In the original wording group the head tilt-chin manoeuvre was executed by 0.0% of the lay rescuers compared to 70.3% in the group with modified wording (p

Abstract Background Responsive and efficient emergency medical services (EMS) require accurate telephone triage. In Finland, such services are provided by Emergency Response Centre Agency (ERC Agency). In 2018, a new Finnish computer-assisted emergency dispatch system was introduced: the Emergency Response Integrated Common Authorities (ERICA). After the introduction of ERICA, the appropriateness of EMS dispatch has not been investigated yet. The study´s objective is to determine the consistency between the priority triage of the emergency medical dispatcher (EMD) and the on-scene priority assessment of the EMS, and whether the priority assessment consistency varied among the dispatch categories. Methods This was a prospective register-based study. All EMS dispatches registered in the Tampere University Hospital area from 1 August 2021 to 31 August 2021 were analysed. The EMD’s mission priority triaged during the emergency call was compared with the on-scene EMS’s assessment of the priority, derived from the pre-set criteria. The test performance levels were measured from the crosstabulation of true or false positive and negative values of the priority assessment. Statistical significance was analysed using the chi-square test and the Kruskal–Wallis H test, and p-values

Abstract Background Urinary tract infection (UTI) is particularly common in young women and the elderly. The Emergency Medical Services (EMS) in Copenhagen, Denmark can be reached by calling either of two dedicated telephone lines: 1–1-2 in case of an emergency and 1813 during general practitioner’s (GP) out-of-office hours (OOH). This study investigated characteristics of patients with symptoms of UTI calling the Copenhagen EMS and the response they received. Methods A retrospective observational cohort study was conducted in which 7.5 years of telephone data on UTI from the EMS in Copenhagen were analyzed. Descriptive statistics and multinomial logistic regression were used to analyze patient characteristics, the timing of the incident and response. Patients’ age and gender were assessed and the use of urinary catheters, the timing of the incident, and the impact on the response were evaluated. Results A total of 278.961 calls were included (78% female, mean age 47), with an average of 120 patients with UTI symptoms calling each day. Most people contacted the 1813-medical helpline (98%) and of those, the majority were referred to the emergency department (ED)(37%). Patients were more likely to be referred to the ED during the weekend compared to a weekday and less likely during OOH compared to in-office hours (IH). Patients with a urinary catheter were more likely to receive specialized care referred to as ‘other’. For the smaller proportion of patients calling 1–1-2, most people got a B (urgent) response (1.5%). The most likely response to be given was an A (emergency) or F (non-emergency) response during OOH compared to IH and on weekends compared to weekdays. Patients with a urinary catheter were more likely to receive a D (unmonitored transport) response. Conclusions Since 2015, there was a decrease in 1813 antibiotic prescription rates and a subsequent increase in referral to the ED of UTI patients. Patients were referred less to the ED during OOH as they were likely to be sent to their GP the next day. During the weekend, patients were referred more to the ED for the likely reason that their GP is closed.

- Abstract
Background: Helicopter Emergency Medical Services (HEMS) are a limited and expensive resource, and should be intelligently tasked. HEMS dispatch was identified as a key research priority in 2011, with a call to identify a 'general set of criteria with the highest discriminating potential'. However, there have been no published data analyses in the past decade that specifically address this priority, and this priority has been reaffirmed in 2023. The objective of this study was to define the dispatch criteria available at the time of the initial emergency call with the greatest HEMS utility using a large, regional, multi-organizational dataset in the UK. Methods: This retrospective observational study utilized dispatch data from a regional emergency medical service (EMS) and three HEMS organisations in the East of England, 2016–2019. In a logistic regression model, Advanced Medical Priority Dispatch System (AMPDS) codes with ≥ 50 HEMS dispatches in the study period were compared with the remainder to identify codes with high-levels of HEMS patient contact and HEMS-level intervention/drug/diagnostic (HLIDD). The primary outcome was to identify AMPDS codes with a > 10% HEMS dispatch rate of all EMS taskings that would result in 10–20 high-utility HEMS dispatches per 24-h period in the East of England. Data were analysed in R, and are reported as number (percentage); significance was p < 0.05. Results: There were n = 25,491 HEMS dispatches (6400 per year), of which n = 23,030 (90.3%) had an associated AMPDS code. n = 13,778 (59.8%) of HEMS dispatches resulted in patient contact, and n = 8437 (36.6%) had an HLIDD. 43 AMPDS codes had significantly greater rates of patient contact and/or HLIDD compared to the reference group. In an exploratory analysis, a cut-off of ≥ 70% patient contact rate and/or ≥ 70% HLIDD (with a > 10% HEMS dispatch of all EMS taskings) resulted in 17 taskings per 24-h period. This definition derived nine AMPDS codes with high HEMS utility. Conclusion: We have identified nine 'golden' AMPDS codes, available at the time of initial emergency call, that are associated with high-levels of whole-system and HEMS utility in the East of England. We propose that UK EMS should consider immediate HEMS dispatch to these codes. [ABSTRACT FROM AUTHOR]

Abstract Background Emergency medical dispatchers typically use the dispatch code for suspected stroke when the caller brings up one or more symptoms from the face-arm-speech triad. Paramedics and emergency department physicians are trained to suspect large vessel occlusion stroke when the stroke patient presents with hemiparesis and cortical symptoms: neglect, aphasia, and conjugate eye deviation (CED). We hypothesized that these symptoms could be evident in the emergency call. In this study, we aimed to describe common symptoms mentioned in the emergency calls for paramedic-suspected thrombectomy candidates. Secondly, we wanted to explore how the question about CED arises in the Finnish suspected stroke dispatch protocol. Our third aim was to find out if the symptoms brought up in suspected stroke and non-stroke dispatches differed from each other. Methods This was a retrospective study with a descriptive analysis of emergency calls for patients with paramedic-suspected large vessel occlusion stroke. We listened to the emergency calls for 157 patients transported to Tampere University Hospital, a Finnish comprehensive stroke centre. Two researchers listened for symptoms brought up in these calls and filled out a pre-planned case report form. Results Speech disturbance was the most common symptom brought up in 125 (80%) calls. This was typically described as an inability to speak any words (n = 65, 52% of calls with speech disturbance). Other common symptoms were falling down (n = 63, 40%) and facial asymmetry (n = 41, 26%). Suspicion of stroke was mentioned by 44 (28%) callers. When the caller mentioned unconsciousness the emergency dispatcher tended to use a non-stroke dispatch code. The dispatchers adhered poorly to the protocol and asked about CED in only 57% of suspected stroke dispatches. We found CED in 12 emergency calls and ten of these patients were diagnosed with large vessel occlusion. Conclusion In cases where paramedics suspected large vessel occlusion stroke, typical stroke symptoms were described during the emergency call. Speech disturbance was typically described as inability to say anything. It is possible to further develop suspected stroke dispatch protocols to recognize thrombectomy candidates from ischemic cortical signs such as global aphasia and CED.

Background: Telephone-Cardiopulmonary Resuscitation (T-CPR) significantly increases rate of bystander resuscitation and improves patient outcomes after out-of-hospital cardiac arrest (OHCA). Nevertheless, securing correct execution of instructions remains a difficulty. ERC Guidelines 2021 recommend standardised instructions with continuous evaluation. Yet, there are no explicit recommendations on a standardised wording of T-CPR in the German language. We investigated, whether a modified wording regarding check for breathing in a German T-CPR protocol improved performance of T-CPR. Methods: A simulation study with 48 OHCA scenarios was conducted. In a non-randomised trial study lay rescuers were instructed using the real-life-CPR protocol of the regional dispatch centre and as the intervention a modified T-CPR protocol, including specific check for breathing (head tilt-chin lift instructions). Resuscitation parameters were assessed with a manikin and video recordings. Results: Check for breathing was performed by 64.3% (n = 14) of the lay rescuers with original wording and by 92.6% (n = 27) in the group with modified wording (p = 0.035). In the original wording group the head tilt-chin manoeuvre was executed by 0.0% of the lay rescuers compared to 70.3% in the group with modified wording (p < 0.001). The average duration of check for breathing was 1 ± 1 s in the original wording group and 4 ± 2 s in the group with modified wording (p < 0.001). Other instructions (e.g. check for consciousness and removal of clothing) were well performed and did not differ significantly between groups. Quality of chest compression did not differ significantly between groups, with the exception of mean chest compression depth, which was slightly deeper in the modified wording group. Conclusion: Correct check for breathing seems to be a problem for lay rescuers, which can be decreased by describing the assessment in more detail. Hence, T-CPR protocols should provide standardised explicit instructions on how to perform airway assessment. Each protocol should be evaluated for practicability. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Responsive and efficient emergency medical services (EMS) require accurate telephone triage. In Finland, such services are provided by Emergency Response Centre Agency (ERC Agency). In 2018, a new Finnish computer-assisted emergency dispatch system was introduced: the Emergency Response Integrated Common Authorities (ERICA). After the introduction of ERICA, the appropriateness of EMS dispatch has not been investigated yet. The study´s objective is to determine the consistency between the priority triage of the emergency medical dispatcher (EMD) and the on-scene priority assessment of the EMS, and whether the priority assessment consistency varied among the dispatch categories. Methods: This was a prospective register-based study. All EMS dispatches registered in the Tampere University Hospital area from 1 August 2021 to 31 August 2021 were analysed. The EMD's mission priority triaged during the emergency call was compared with the on-scene EMS's assessment of the priority, derived from the pre-set criteria. The test performance levels were measured from the crosstabulation of true or false positive and negative values of the priority assessment. Statistical significance was analysed using the chi-square test and the Kruskal–Wallis H test, and p-values < 0.05 were considered significant. Results: Of the 6416 EMS dispatches analysed in this study, 36% (2341) were urgent according to the EMD's dispatch priority, and of these, only 29% (688) were urgent according to the EMS criteria. On the other hand, 64% (4075) of the dispatches were non-urgent according to the EMD's dispatch priority, of which 97% (3949) were non-urgent according to the EMS criteria. Moreover, there were differences between the EMD and EMS priority assessments among the dispatch categories (p < 0.001). The overall efficiency was 72%, sensitivity 85%, specificity 71%, positive predictive value 29%, and negative predictive value 97%. Conclusion: While the EMD recognised the non-urgent dispatches with high consistency with the EMS criteria, most of the EMD's urgent dispatches were not urgent according to the same criteria. This may diminish the availability of the EMS for more urgent missions. Thus, measures are needed to ensure more accurate and therefore, more efficient use of EMS resources in the future.

Abstract Objectives To develop emergency medical dispatch (EMD) centre prediction models with high sensitivity and satisfying specificity to identify high-priority patients and patients suitable for non-emergency care respectively, when assessing patients with chest pain. Methods Observational cohort study of 2917 unselected patients with chest pain who contacted an EMD centre in Sweden due to chest pain during 2018. Multivariate logistic regression was applied to develop models predicting low-risk or high-risk condition, that is, occurrence of time-sensitive diagnosis on hospital discharge. Results Prediction models were developed for the identification of patients suitable for high- and low-priority dispatch, using 11 and 10 variables respectively. The area under the receiver-operating characteristic curve (AUROC) for the high-risk prediction model was 0.79 and for the low-risk model it was 0.74. When applying the high-risk prediction model, 56% of the EMS missions were given highest priority, compared with 65% with the current standard. When applying the low-risk model, 7% were given the lowest priority compared to 1% for the current standard. The new prediction models outperformed today’s dispatch priority accuracy in terms of sensitivity as well as positive and negative predictive value in both high- and low-risk prediction. The low-risk model predicted almost six times as many patients as having low-risk conditions compared with today’s standard. This was done without increasing the number of high-risk patients wrongly assessed as low-risk. Conclusions By introducing prediction models, based on logistic regression analyses, using variables obtained by standard EMD-questions on age, sex, medical history and symptomology, EMD prioritisation can be improved compared with using current criteria index-based ones. This will allow a more efficient emergency medical services resource allocation.

Why is neighborhood racial composition linked so strongly to police-reported crime? Common explanations include over-policing and negative interactions with police, but police reports of crime are heavily dependent on resident 911 calls. Using Sampson's concept of legal cynicism and Vaisey's dual-process theory, we theorize that racial concentration and isolation consciously and nonconsciously influence neighborhood variation in 911 calls for protection and prevention. The data we analyze are consistent with this thesis. Independent of police reports of crime, we find that neighborhood racial segregation in 1990 and the legal cynicism about crime prevention and protection it engenders have lasting effects on 911 calls more than a decade later, in 2006-2008. Our theory explains this persistent predictive influence through continuity and change in intervening factors. A source of cumulative continuity, the intensification of neighborhood racial concentration and isolation between 1990 and 2000, predicts 911 calls. Likewise, sources of change-heightened neighborhood incarceration and home foreclosures during the financial crisis in 2006-2008-also predict these calls. Our findings are consistent with legal cynicism theory's focus on neighborhood disadvantage, racial isolation, and concerns about police protection and crime prevention; they correspond less with the emphasis of procedural justice theory on police legitimacy.

BACKGROUND:Excessive alcohol consumption is associated with a substantial number of emergency department visits annually and is responsible for a significant number of lives lost each year in the United States. However, a minimal amount is known about the impact of alcohol on the EMS system. OBJECTIVES:The primary objective was to determine the proportion of 9-1-1 calls in Denver, Colorado in which (1) alcohol was a contributing factor or (2) the individual receiving EMS services had recently ingested alcohol. The secondary objectives were to compare the characteristics of EMS calls and to estimate the associated costs. METHODS:This was a prospective observational cohort study of EMS calls for adults from July 1, 2012, to June 30, 2014. Primary outcomes for the study were alcohol as a contributing factor to the EMS call and recent alcohol consumption by the patient receiving EMS services. Logistic regression was utilized to determine the associations between EMS call characteristics and the outcomes. Cost was estimated using historic data. RESULTS:During the study period, 169,642 EMS calls were completed by the Denver Health Paramedic Division. Of these 71% were medical and 29% were trauma-related. The median age was 45 (interquartile range [IQR] 29-59) years, and 55% were male. 50,383 calls (30%) had alcohol consumption, and 49,165 (29%) had alcohol as a contributing factor. Alcohol related calls were associated with male sex, traumatic injuries including head trauma, emergent response, use of airway adjuncts, cardiac monitoring, glucose measurement, use of restraints, use of spinal precautions, and administration of medications for sedation. Estimated costs to the EMS system due to alcohol intoxication exceeded $14 million dollars over the study period and required in excess of 37 thousand hours of paramedic time. CONCLUSIONS:Compared to 9-1-1 calls that do not involve alcohol, alcohol-related calls are more likely to involve male patients, emergent response, traumatic injuries, advanced monitoring, airway adjuncts, and medications for sedation. This represents a significant burden on the emergency system and society. Further studies are needed to evaluate whether additional interventions such as social services could be used to lessen this burden.

- Abstract
A growing number of individuals with unmet mental health needs in the United States rely on emergency medical services during mental health crises, and 9-1-1 emergency medical dispatchers (EMD) are often a critical lifeline to help. Unfortunately, current industry-standard dispatching protocols and training required for EMD certification largely lack specificity for managing 9-1-1 calls related to mental health emergencies. The purpose of this report is to illustrate the value of additional targeted training for EMDs that enables them to more effectively assist callers struggling with mental illness or suicidal thoughts. We review a 9-1-1 call in which an EMD utilized specific strategies and language learned during a 3-day emergency mental health dispatch (EMHD) training course to assist a middle-aged male who was expressing suicidal intent with a firearm. Key principles and phrasing from the training were used successfully by the EMD to dissuade the caller from self-harm, and he was ultimately safely met by first responders on scene and transported for care. We also share post-call recollections and reactions from the EMD to demonstrate how in addition to reducing risks for callers and their families, EMHD training has the potential to reduce on-scene risks for field responders and may increase confidence and mitigate negative stress responses in EMDs. Emergency medical services systems in the United States should continue to explore enhanced training and protocols to improve care for 9-1-1 callers experiencing mental health crises.

- Abstract
Objectives: Emergency medical services (EMS) systems increasingly grapple with rising call volumes and workforce shortages, forcing systems to decide which responses may be delayed. Limited research has linked dispatch codes, on-scene findings, and emergency department (ED) outcomes. This study evaluated the association between dispatch categorizations and time-critical EMS responses defined by prehospital interventions and ED outcomes. Secondarily, we proposed a framework for identifying dispatch categorizations that are safe or unsafe to hold in queue., Methods: This retrospective, multi-center analysis encompassed all 9-1-1 responses from 8 accredited EMS systems between 1/1/2021 and 06/30/2023, utilizing the Medical Priority Dispatch System (MPDS). Independent variables included MPDS Protocol numbers and Determinant levels. EMS treatments and ED diagnoses/dispositions were categorized as time-critical using a multi-round consensus survey. The primary outcome was the proportion of EMS responses categorized as time-critical. A non-parametric test for trend was used to assess the proportion of time-critical responses Determinant levels. Based on group consensus, Protocol/Determinant level combinations with at least 120 responses (∼1 per week) were further categorized as safe to hold in queue (<1% time-critical intervention by EMS and <5% time-critical ED outcome) or unsafe to hold in queue (>10% time-critical intervention by EMS or >10% time-critical ED outcome)., Results: Of 1,715,612 EMS incidents, 6% (109,250) involved a time-critical EMS intervention. Among EMS transports with linked outcome data (543,883), 12% had time-critical ED outcomes. The proportion of time-critical EMS interventions increased with Determinant level (OMEGA: 1%, ECHO: 38%, p-trend < 0.01) as did time-critical ED outcomes (OMEGA: 3%, ECHO: 31%, p-trend < 0.01). Of 162 unique Protocols/Determinants with at least 120 uses, 30 met criteria for safe to hold in queue, accounting for 8% (142,067) of incidents. Meanwhile, 72 Protocols/Determinants met criteria for unsafe to hold, accounting for 52% (883,683) of incidents. Seven of 32 ALPHA level Protocols and 3/17 OMEGA level Protocols met the proposed criteria for unsafe to hold in queue., Conclusions: In general, Determinant levels aligned with time-critical responses; however, a notable minority of lower acuity Determinant level Protocols met criteria for unsafe to hold. This suggests a more nuanced approach to dispatch prioritization, considering both Protocol and Determinant level factors.

- Abstract
Objective: The number of patients using emergency medical services (EMS) through ambulance dispatch has been increasing annually in Taiwan. Due to limited medical resource allocation, patients may not get on-time admission after they are sent to a hospital Emergency Department. This study aimed to construct a forecasting system to predict the availability of ED and ICU beds., Materials and Methods: A simulation-based forecasting system integrated with Google Maps is proposed to provide ED recommendations for ambulance dispatch. The web crawler technique continuously collects open data from the emergency information systems. An arrival transfer mechanism was proposed to convert the raw data into a simulation input. The results were then integrated with hospital assessment and routing distance in Google Maps to provide the most appropriate hospital ED to which a patient should be sent., Results: The results provided forecast accuracy for bed availability for the next 20, 40, and 60 min in 10 selected hospitals in central Taiwan. In most hospitals, the forecasting accuracy is high. For example, the ED and ICU bed availability accuracies in the next 20, 40, and 60 min are [100%, 88.7%], [100%, 90.5%], and [100%, 92.1%]. The two scenarios also showed hospital recommendations based on the available beds, routing distance, and eight-dimensional assessments., Conclusion: Previous EMS research usually did not consider future bed availability as the research target. This study predicted future bed availability and recommended the most appropriate hospitals for EMS dispatchers., Competing Interests: Declarations.

Abstract Background The requirement concerning formal education for emergency medical dispatcher (EMD) is debated and varies, both nationally and internationally. There are few studies on the outcomes of emergency medical dispatching in relation to professional background. This study aimed to compare calls handled by an EMD with and without support by a registered nurse (RN), with respect to priority level, accuracy, and medical condition. Methods A retrospective observational study, performed on registry data from specific regions during 2015. The ambulance personnel’s first assessment of the priority level and medical condition was used as the reference standard. Outcomes were: the proportion of calls dispatched with a priority in concordance with the ambulance personnel’s assessment; over- and undertriage; the proportion of most adverse over- and undertriage; sensitivity, specificity and predictive values for each of the ambulance priorities; proportion of calls dispatched with a medical condition in concordance with the ambulance personnel’s assessment. Proportions were reported with 95% confidence intervals. χ2-test was used for comparisons. P-levels

Aims and objectives: To describe strategies employed by registered nurses for handling difficult calls to emergency medical dispatch centres. Background: At emergency medical dispatch centres, registered nurses encounter a range of difficult calls in their clinical practice. They often use clinical decision support systems, but these may be of limited help if the caller is for instance abusive or has limited language proficiency. Much can be learnt from strategies developed by registered nurses for handling difficult calls. Design: A descriptive qualitative study was conducted. Methods: A purposeful sample of 24 registered nurses from three different emergency medical dispatch centres were interviewed. The transcribed interviews were analysed using qualitative content analysis. The COREQ checklist was applied. Results: An overarching theme was established: "Using one's nursing competence and available resources for a safe outcome", based on three sub‐themes: Use one's own professional and personal resources, Use resources within the organisation and Use external resources. The themes in turn consist of ten categories. Conclusions: Registered nurses employed a range of strategies to deal with difficult calls, often in combination. They used their personal resources, resources within their own organisation, and collaboration partners to make safe triage decisions and use resources wisely. The effectiveness of these strategies, however, remains unknown. When registered nurses were unable to rule out a high‐acuity condition, they used safety‐netting and sent an ambulance. Evaluating current strategies and making strategies explicit could further improve the ability of nurses to handle difficult calls. Relevance to clinical practice: The strategies described by registered nurses for handling difficult calls to EMDCs included using a consecutive set of strategies. Some of the strategies seemed to be used deliberately, while others seemed tacit and applied in a routinised way. These strategies could potentially be useful for RNs working with telephone triage in different contexts. [ABSTRACT FROM AUTHOR]

Background: Emergency medical dispatchers typically use the dispatch code for suspected stroke when the caller brings up one or more symptoms from the face-arm-speech triad. Paramedics and emergency department physicians are trained to suspect large vessel occlusion stroke when the stroke patient presents with hemiparesis and cortical symptoms: neglect, aphasia, and conjugate eye deviation (CED). We hypothesized that these symptoms could be evident in the emergency call. In this study, we aimed to describe common symptoms mentioned in the emergency calls for paramedic-suspected thrombectomy candidates. Secondly, we wanted to explore how the question about CED arises in the Finnish suspected stroke dispatch protocol. Our third aim was to find out if the symptoms brought up in suspected stroke and non-stroke dispatches differed from each other. Methods: This was a retrospective study with a descriptive analysis of emergency calls for patients with paramedic-suspected large vessel occlusion stroke. We listened to the emergency calls for 157 patients transported to Tampere University Hospital, a Finnish comprehensive stroke centre. Two researchers listened for symptoms brought up in these calls and filled out a pre-planned case report form. Results: Speech disturbance was the most common symptom brought up in 125 (80%) calls. This was typically described as an inability to speak any words (n = 65, 52% of calls with speech disturbance). Other common symptoms were falling down (n = 63, 40%) and facial asymmetry (n = 41, 26%). Suspicion of stroke was mentioned by 44 (28%) callers. When the caller mentioned unconsciousness the emergency dispatcher tended to use a non-stroke dispatch code. The dispatchers adhered poorly to the protocol and asked about CED in only 57% of suspected stroke dispatches. We found CED in 12 emergency calls and ten of these patients were diagnosed with large vessel occlusion. Conclusion: In cases where paramedics suspected large vessel occlusion stroke, typical stroke symptoms were described during the emergency call. Speech disturbance was typically described as inability to say anything. It is possible to further develop suspected stroke dispatch protocols to recognize thrombectomy candidates from ischemic cortical signs such as global aphasia and CED. [ABSTRACT FROM AUTHOR]

Background: Hardships associated with the ongoing coronavirus disease 2019 (COVID-19) pandemic can affect mental health, potentially leading to increased risk of suicide. We examined the relationship between the COVID-19 outbreak and suicide attempts in Okayama, Japan using information from emergency dispatches. Methods: This was a descriptive epidemiological study. We collected information on emergency dispatches in Okayama City and Kibichuo from March to August in 2018, 2019, and 2020 (n = 47,770 cases). We compared emergency dispatches and their demographic characteristics, especially focusing on suicide attempts, during these 3 years. Results: The number of emergency dispatches in 2020 decreased compared with the previous 2 years, while the number and proportion of emergency dispatches related to suicide attempts increased. This increase was more pronounced among women and those aged 25–49 years. Among women aged 25–49 years, there was a cumulative total of 43 suicide attempts in 2018 and 2019 and 73 suicide attempts in 2020. Conclusions: The number and proportion of emergency dispatches related to suicide attempts increased in 2020 compared with the previous 2 years, especially among women and those aged 25–49 years. This increase may be partly explained by hardships, such as economic losses or reduced social ties, during the COVID-19 outbreak.
