improving Pain mAnagement for childreN and young people attendeD by Ambulance (PANDA): protocol for a realist review.

Background: Each year in England, 450,000 children and young people (CYP) under 18 years of age are transported by ambulance to emergency departments. Approximately 20% of these suffer acute pain caused by illness or injury. Pain is a highly complex sensory and emotional experience. The intersection between acute pain, unwell CYP and the unpredictable pre-hospital environment is convoluted. Studies have shown that prehospital pain management in CYP is poor, with 61% of those suffering acute pain not achieving effective pain relief (abolition or reduction of pain score by 2 or more out of 10) when attended by ambulance. Consequences of poor acute pain management include altered pain perception, post-traumatic stress disorder and the development of chronic pain. This realist review will aim to understand how ambulance clinicians can provide improved prehospital acute pain management for CYP. Methods: A realist review will be conducted in accordance with the Realist And Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) guidance. A five-stage approach will be adopted; 1) Developing an Initial Programme Theory (IPT): develop an IPT with key stakeholder input and evidence from informal searching; 2) Searching and screening: conduct a thorough search of relevant research databases and other literature sources and perform screening in duplicate; 3) Relevance and rigour assessment: assess documents for relevance and rigour in duplicate; 4) Extracting and organising data: code relevant data into conceptual "buckets" using qualitative data analysis software; and 5) Synthesis and Programme Theory (PT) refinement: utilise a realist logic of analysis to generate context-mechanism-outcome configurations (CMOCs) within and across conceptual "buckets", test and refine the IPT into a realist PT. Conclusion: The realist PT will enhance our understanding of what works best to improve acute prehospital pain management in CYP, which will then be tested and refined within a realist evaluation.

Ambulance Transports from NCAA Division 1 Football Games.

INTRODUCTION: There is significant public health interest towards providing medical care at mass-gathering events. Furthermore, mass gatherings have the potential to have a detrimental impact on the availability of already-limited municipal Emergency Medical Services (EMS) resources. This study presents a cross-sectional descriptive analysis to report broad trends regarding patients who were transported from National Collegiate Athletic Association (NCAA) Division 1 collegiate football games at a major public university in order to better inform emergency preparedness and resource planning for mass gatherings. METHODS: Patient care reports (PCRs) from ambulance transports originating from varsity collegiate football games at the University of Minnesota across six years were examined. Pertinent information was abstracted from each PCR. RESULTS: Across the six years of data, there were a total of 73 patient transports originating from NCAA collegiate football games: 45.2% (n = 33) were male, and the median age was 22 years. Alcohol-related chief complaints were involved in 50.7% (n = 37) of transports. In total, 31.5% of patients had an initial Glasgow Coma Scale (GCS) of less than 15. The majority (65.8%; n = 48; 0.11 per 10,000 attendees) were transported by Basic Life Support (BLS) ambulances. The remaining patients (34.2%; n = 25; 0.06 per 10,000 attendees) were transported by Advanced Life Support (ALS) ambulances and were more likely to be older, have abnormal vital signs, and have a lower GCS. CONCLUSIONS: This analysis of ambulance transports from NCAA Division 1 collegiate football games emphasizes the prevalence of alcohol-related chief complaints, but also underscores the likelihood of more life-threatening conditions at mass gatherings. These results and additional research will help inform emergency preparedness at mass-gathering events.

Routine outcomes to investigate differences between ethnic minorities and White British people presenting to emergency services for injury: the stakeholder consultation.

Introduction: Research has found differences in processes and outcomes of care between people in ethnic minorities and White British populations in some clinical conditions, although findings have been mixed. The Building an understanding of Ethnic minority people's Service Use Relating to Emergency care for injuries study is investigating differences in presentation, experience and health outcomes between people from ethnic minorities and White British people who seek emergency health care for injury. Objective: Our aim was to consult with stakeholders to define measurable outcomes available in routine ambulance and emergency department data; to assess the appropriateness of existing outcome measures for ethnic minorities and White British people; and to identify any gaps. Method: Clinicians, public contributors, researchers, people from the third sector, public health, healthcare inclusion were invited to join an online workshop to discuss routine outcomes. Results: Twenty participants attended the stakeholder consultation, with only one being a public contributor, a limitation. Eleven were from a minority ethnic background and seven were female. The integrated list of outcomes included 25 items, combining routine outcomes from the Building an understanding of Ethnic minority people's Service Use Relating to Emergency care for injuries protocol and literature (n = 17) with additional outcomes (n = 8). Notably, the initial list lacked provisions for safeguarding referrals and cases of treatment refusal, which were new additions. Safety concerns arose due to the lack of safeguarding referrals, treatment refusal and self-discharge. Factors such as pre-existing health conditions, injury location and experiences of discrimination were identified as possible influences on care quality and waiting times for ethnic minority patients. Conclusion: Although the number of stakeholders taking part in our consultation was low, their participation identified outcomes not found in routine data, supporting the adoption of a mixed-methods approach to answer our research questions. A future consultation could look to include more public members and wider range of clinicians including those who work in safeguarding and rehabilitation services. Funding: This article presents independent research funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme as award number NIHR132744.

Research has shown that people from ethnic minorities often have less favourable healthcare experiences and outcomes than white British people. Our BE SURE study aims to establish whether there are differences between these groups and whether this can be seen in routinely available health outcome data or through patients' own words through questionnaires and interviews. Before starting data collection, we wanted to consult with people who may deliver or receive emergency health care for injuries, about what routinely available healthcare measures and outcomes we should include in the study. Twenty stakeholders joined the meeting: clinicians, paramedics, researchers and representatives from healthcare organisations, the third sector and a public contributor. We firstly explained what the study was about, and what we hoped to achieve during the online consultation meeting. We presented examples of measurable outcomes that we had included in our original research proposal for injuries. We broke into small groups to discuss these outcome measures and identify gaps. We also asked for comments and suggestions to check the appropriateness of these measures. Participants agreed that the proposed measures were mostly appropriate; these included tests, treatments, waiting times, referrals to other doctors, leaving the hospital against medical advice and time spent in the emergency department. They identified two new outcomes, which were safeguarding referrals and refusal of treatment. The final agreed list of outcomes was 25. Participants also discussed disparities in medication and treatments provided to ethnic minorities compared to white British people, such as pain relief. Additionally, they explored various factors that could affect care differently across these groups. For instance, ethnic minorities may experience discrimination, have distinct health issues or experience variations in the location, nature and severity of injuries. These factors could influence waiting times, pain management and overall quality of care.

A newly developed, easy-to-use prehospital drug-derived score compared with three conventional scores: A prospective multicenter study.

INTRODUCTION: The use of medications by emergency medical services (EMS) is increasing. Conventional scores are time-consuming and therefore difficult to use in an emergency setting. For early decision-making, an easy-to-use score based on the medications administered by the EMS may have prognostic value. The primary objective of this study was to develop the prehospital drug-derived score (PDDS) for 2-day mortality. METHODS: A prospective, multicenter, ambulance-based cohort study was conducted in adults with undifferentiated acute diseases treated by EMS and transferred to the emergency department. Demographic data, prehospital diagnosis data, prehospital medication and variables for the calculation of the National Early Warning Score 2 (NEWS2), Rapid Emergency Medicine Score (REMS), and Rapid Acute Physiology Score (RAPS) were collected. The PDDS was developed and validated, establishing three levels of risk of 2-day mortality. The predictive capability of each score was determined by the area under the curve of the receiver operating characteristic curve (AUROC) and compared using the Delong's test (p-value). RESULTS: A total of 6401 patients were included. The PDDS included age and the use of norepinephrine, analgesics, neuromuscular blocking agents, diuretics, antihypertensive agents, tranexamic acid, and bicarbonate. The AUROC of PDDS was .86 (95% CI: .816-.903) versus NEWS2 .866 (95% CI: .822-.911), p = .828; versus REMS .885 (95% CI: .845-.924), p = .311; versus RAPS .886 (95% CI: .846-.926), p = .335, respectively. CONCLUSION: The newly developed easy-to-use prehospital drug-derived PDDS score has an excellent predictive value of early mortality. The PDDS score was comparable to the conventional risk scores and therefore might serve as an alternative score in the prehospital emergency setting.

2024 Systematic Review of Evidence-Based Guidelines for Prehospital Care.

OBJECTIVES: Evidence-based guidelines (EBGs) are widely recognized as valuable tools to aggregate and translate scientific knowledge into clinical care. High-quality EBGs can also serve as important components of dissemination and implementation efforts focused on educating emergency medical services (EMS) clinicians about current evidence-based prehospital clinical care practices and operations. We aimed to perform the third biennial systematic review of prehospital EBGs to identify and assess the quality of prehospital EBGs published since 2021. METHODS: We systematically searched Ovid Medline and EMBASE from January 1, 2021, to June 6, 2023, for publications relevant to prehospital care, based on an organized review of the literature, and focused on providing recommendations for clinical care or operations. Included guidelines were appraised using the National Academy of Medicine (NAM) criteria for high-quality guidelines and scored using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Tool. RESULTS: We identified 33 new guidelines addressing clinical and operational topics of EMS medicine. The most addressed EMS core content areas were time-life critical conditions (n = 17, 51.5%), special clinical considerations (n = 15, 45%), and injury (n = 12, 36%). Seven (21%) guidelines included all elements of the National Academy of Medicine (NAM) criteria for high-quality guidelines, including the full reporting of a systematic review of the evidence. Guideline appraisals by the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool demonstrated modest compliance to reporting recommendations and similar overall quality compared to previously identified guidelines (mean overall domain score 67%, SD 12%), with Domain 5 ("Applicability") scoring the lowest of the six AGREE II domains (mean score of 53%, SD 13%). CONCLUSIONS: This updated systematic review identified and appraised recent guidelines addressing prehospital care and identifies important targets for education of EMS personnel. Continued opportunities exist for prehospital guideline developers to include comprehensive evidence-based reporting into guideline development to facilitate widespread implementation of high-quality EBGs in EMS systems and incorporate the best available scientific evidence into initial education and continued competency activities.

The Burden of Non-Protocolized Patient Transport Outside of Response Area on a Rural EMS System.

OBJECTIVES: Transport destination decisions by prehospital personnel depend on a combination of protocols, judgement, patient acuity, and patient preference. Non-protocolized transport outside the service area may result in unnecessary time out of service and inappropriate resource utilization. Scant research exists regarding clinician rationale for destination decisions. METHODS: We retrospectively reviewed one year of scene transports by a single rural, hospital-based EMS system. We collected dispatch, patient demographic, primary impression, and transport data from prehospital records and matched them to Emergency Department (ED) data. We characterized rationale for transport decisions and compared rates of hospital admission and specialist consultation in the ED as surrogates for decision appropriateness. RESULTS: We reviewed 2,223 patient transports, 281 of which were transported out of the service area. The most common reasons for out-of-area transport were patient preference NOT related to prior medical care (40%) and clinician judgement (24%). Admit rates were highest for per protocol (85%) and patient preference related to prior medical care (67%) groups and lowest for no explanation (41%) and clinician judgement (47%) groups. Rates of in person specialist consultation in the ED were highest in per protocol (69%) and clinician judgement (47%) groups and lowest in no explanation (23%) and patient preference NOT related to prior medical care (30%) groups. Clinician judgement was less predictive of admission and specialist consultation for non-trauma and pediatric patients than for all patients. Median time out of service was more than twice as long for out-of-area transports (140 min) compared to patients transported to the nearest facility (62 min). For out-of-area transports discharged from the ED without specialty consultation (n = 104), ambulances travelled an additional 52 miles/patient compared to theoretical transport to nearest facility. CONCLUSIONS: Unit out of service time more than doubled for non-protocolized transports outside of the service area and rationale for destination decisions variably predicted admission and specialist consultation rates. Patient preference NOT related to prior medical care and, in pediatric and non-trauma populations, clinician judgement, were less predictive of admission and specialist consultation. Transport guidelines should balance rationale for transport destination and patient characteristics with resource preservation, especially in low-resource systems.

The performance of screening tools and use of blood analyses in prehospital identification of sepsis patients and patients suitable for non-conveyance - an observational study.

BACKGROUND: Early recognition of sepsis by the EMS (Emergency Medical Services), along with communicating this concern to the emergency department, could improve patient prognosis and outcome. Knowledge is limited about the performance of sepsis identification screening tools in the EMS setting. Research is also limited on the effectiveness of prehospital use of blood tests for sepsis identification. Integrating blood analyses with screening tools could improve sepsis identification, leading to prompt interventions and improved patient outcomes. AIM: The aim of the present study is firstly to evaluate the performance of various screening tools for sepsis identification in the EMS setting and secondly to assess the potential improvement in accuracy by incorporating blood analyses. METHODS: This is a retrospective observational cohort study. The data were collected from prehospital and hospital medical records in Region Halland. Data on demographics, vital signs, blood tests, treatment, and outcomes were collected from patients suspected by EMS personnel of having infection. The data were analysed using Student's t-test. Sensitivity, specificity, positive predictive value, negative predictive value and odds ratio were used to indicate accuracy and predictive value. RESULTS: In total, 5,405 EMS missions concerning 3,225 unique patients were included. The incidence of sepsis was 9.8%. None of the eleven tools included had both high sensitivity and specificity for sepsis identification. White blood cell (WBC) count was the blood analysis with the highest sensitivity but the lowest specificity for identifying sepsis. Adding WBC, C-reactive protein (CRP) or lactate to the National Early Warning Score (NEWS) increased the specificity to > 80% but substantially lowered the sensitivity. CONCLUSIONS: Identifying sepsis in EMS settings remains challenging, with existing screening tools offering limited accuracy. CRP, WBC, and lactate blood tests add minimal predictive value in distinguishing sepsis or determining non-conveyance eligibility.

From Response to Prevention: Enhancing EMS Impact With Harm Reduction and HIV Education.

EMS are crucial not only for immediate life-saving interventions but also for broader public health initiatives, particularly in harm reduction and HIV prevention. However, many EMS training programs lack comprehensive education and training in these areas, resulting in significant gaps in patient care and provider safety. As the opioid epidemic continues to devastate communities, the need for EMS personnel to be trained in harm reduction strategies, such as naloxone administration, and HIV prevention, has become increasingly urgent. Integrating harm reduction and HIV prevention into EMS training is essential for equipping first responders to effectively address the complex needs of individuals affected by addiction. This training is not only vital for improving public health outcomes but also for ensuring the safety and efficacy of EMS providers in their critical roles on the front lines. The evidence strongly supports the immediate inclusion of harm reduction and HIV prevention in EMS curricula to enhance care quality, reduce the spread of HIV, and combat the ongoing opioid crisis.

Establishing Outcome Parameters for Helicopter Emergency Medical Services Research in the Netherlands: Results of a Mixed-Methods Delphi Consensus Study.

OBJECTIVES: Physician staffed Helicopter Emergency Medical Services (P-HEMS) care in the Netherlands has transitioned from predominantly trauma management to handling a variety of medical conditions. Relevant outcome parameters for Dutch P-HEMS research have not been previously defined. National consensus was sought to identify relevant long term patient outcome parameters, process outcome parameters and performance outcome parameters for Dutch P-HEMS care. METHODS: This was a mixed methods Delphi consensus study. A list of potentially relevant outcome parameters was identified using a systematic literature review. These parameters were subsequently surveyed in a Delphi consensus study. Helicopter Emergency Medical Services physicians and relevant stakeholders were invited to participate in this Delphi survey, where they were allowed to suggest additional outcome parameters. Descriptive analysis was performed on all data sets. RESULTS: Forty-nine potential outcome parameters for Dutch P-HEMS care were surveyed. Of 71 invited participants, 53 (75%), 40 (56%), and 20 (28%) participated in the first, second, and third round of the Delphi study, respectively. Consensus was reached on 25 (51%) of 49 outcome parameters as being important. These consisted of seven long term patient related outcome parameters, four short term patient related outcome parameters, five process outcome parameters and nine performance outcome parameters. CONCLUSIONS: In conclusion, this study identified 25 outcome parameters relevant for Dutch physician staffed HEMS care. These parameters should be considered when designing future studies and should be routinely collected for each dispatch if possible.

Installation of Public Access Defibrillators for Out-of-Hospital Cardiac Arrests: Identifying Suitable Locations by Using a Geographic Information System.

BACKGROUND: Survival following an out-of-hospital cardiac arrest depends on prompt defibrillation. Despite the efforts made to install automated external defibrillators (AEDs) in crowded areas, their usage rate remains suboptimal. This study evaluated the efficiency of installing AEDs at key landmarks in Taoyuan City to enhance accessibility and usage. METHODS AND RESULTS: This retrospective cohort study analyzed nontraumatic public out-of-hospital cardiac arrest cases in Taoyuan City from 2017 to 2021, using data from the Taoyuan Fire Department and a regional registry. AED data were collected for 1163 devices. A geographic information system mapped target locations within the city, and real-world walking routes were examined to assess coverage. The primary outcome was actual coverage and the coverage efficiency ratio, calculated as the actual coverage divided by the number of facilities at a location. The coverage efficiency ratio compared the coverage efficiency of target locations with existing public access defibrillators (PADs). Top locations for superior coverage in both downtown and outside downtown areas were bus stops and convenience stores (7-Eleven and FamilyMart), which outperformed existing PADs. Convenience stores had a higher coverage efficiency ratio than the public service sector. Bus stops showed high AED usage rates before ambulance arrival. CONCLUSIONS: The current PAD locations in Taoyuan City offer limited coverage, which highlights the need for strategically installed AEDs, particularly in convenience stores. Policymakers should consider using the cultural relevance and accessibility of convenience stores, particularly 7-Eleven branches, to enhance AED usage rates.

The Route to ROSC: Evaluating the Impact of Route and Timing of Epinephrine Administration in Out-of-Hospital Cardiac Arrest Outcomes.

OBJECTIVES: Previous investigations comparing intraosseous (IO) and intravenous (IV) epinephrine delivery in out-of-hospital cardiac arrest (OHCA) suggest that epinephrine is oftentimes more expeditiously administered via the IO route, but this temporal benefit doesn't always translate to clinical benefit. However, very few studies adequately controlled for indication and resuscitation time biases, making the influence of first epinephrine route on OHCA outcomes unclear. To determine the association between first epinephrine route and return of spontaneous circulation (ROSC) while controlling for resuscitation time bias and other potential confounders. METHODS: We conducted a retrospective analysis using the 2020 ESO Data Collaborative dataset. Adult patients with a witnessed, non-traumatic OHCA prior to EMS arrival were included. Logistic regression was used to determine the association between medication route and ROSC. Linear regression was then used to calculate the probability of ROSC for each route across all call receipt-to-drug delivery intervals. Using these linear equations, the call receipt-to-drug delivery intervals were calculated that would yield equivalent probabilities of ROSC between the IV and IO routes. RESULTS: Data were available for 10,350 patients, of which 27.4% presented with a shockable rhythm, 29.7% received bystander CPR, and 39.6% experienced ROSC. After controlling for confounders, IO epinephrine was associated with decreased likelihood of ROSC (OR = 0.77, p < 0.001). The linear regression models provided differing slope coefficients for ROSC between each route, with the IV route associated with a higher likelihood of ROSC for any given call receipt-to-drug-delivery interval. From these equations, the additional time allowed to establish an IV and administer epinephrine intravenously beyond the time required for IO delivery, yet with an equivalent predicted probability of ROSC via the IO route, was calculated. This additional time interval for intravenous administration declined linearly from 9 minutes at a call receipt-to-intraosseous epinephrine interval of 4 minutes to no additional time at a call receipt-to-intraosseous epinephrine interval of 29 minutes. CONCLUSIONS: This retrospective analysis of a national EMS database revealed that IO epinephrine was negatively associated with ROSC. Additionally, there appears to be a finite time window during which intravenous epinephrine remains superior to the intraosseous route even if there are brief initial delays in IV drug delivery.

Musculoskeletal disorders in emergency medical services personnel: a systematic review and meta-analysis.

OBJECTIVES: Emergency medical services personnel are frequently subjected to strenuous physical tasks, such as lifting and moving patients, as well as working in awkward postures. These activities can result in a variety of debilitating injuries, including musculoskeletal disorders (MSDs). As a result, this systematic review and meta-analysis study aimed to examine the frequency of MSDs among emergency medical services personnel. STUDY DESIGN: Systematic review and meta-analysis. METHODS: This systematic review and meta-analysis study was conducted based on the PRISMA guidelines. The protocol of this work is registered in PROSPERO with the code CRD42024506958. Searches were conducted without time limits in several databases including PubMed, Scopus, Web of Science, Science Direct, SID, ISC, and Google Scholar until February 12, 2024. The I2 index was used to assess heterogeneity, and random effects model was used for meta-analysis. Data were analyzed using STATA version 14. RESULTS: A total of 709 articles were obtained by initial search in the mentioned databases. Following a thorough screening and quality assessment, 27 articles were chosen for meta-analysis. The findings revealed that the overall prevalence of MSDs among emergency medical services personnel is 56.52% (95% CI: 35-78.04, I2 = 99.8%, P < 0.001) and the prevalence in different areas of the body are as follows: the low back (47.38%), upper back (35.15%), neck (31.19%), shoulder (30%), knee (27.07%), hand (20.70%), hip/thigh (19.48%), feet (19.11%), and elbow (17.36%). CONCLUSION: The prevalence of MSDs among emergency medical services personnel is very high. Considering the importance of the role of these employees and the specific risk factors of their jobs, it is recommended that periodic screening is prioritized. In addition, attention should be paid to the ergonomic evaluation of the work environment and the design of appropriate ergonomic interventions.

The challenges of delivery in pre-hospital emergency medical services ambulances in Iran: a qualitative study.

BACKGROUND: Although unplanned deliveries in ambulances are uncommon, Emergency Medical Services (EMS) providers may encounter this situation before reaching the hospital. This research aims to gather insights from Emergency Medical Technicians (EMTs), midwives, and expectant mothers to examine the causes of giving birth in ambulances and the challenges EMTs, pregnant women, and midwives face during delivery. METHODS: A qualitative study was conducted, and 28 EMTs, midwives, and pregnant women who had experience with pre-hospital births in the ambulance were interviewed. Data were analyzed using thematic content analysis. The MAXQDA/10 software was employed for data analysis and code extraction. RESULTS: The analysis of the interviews revealed two main categories: factors that cause delivery in the ambulance and its challenges. The factors include cultural problems, weak management, and inaccessibility to facilities. The challenges consist of fear and anxiety, native culture, and lack of resources. CONCLUSIONS: Several approaches should be implemented to reduce the number of births in ambulances and Pre-hospital Emergency Medical Services (PEMS). These include long-term community cultural activities, public education, awareness campaigns, education and follow-up for pregnant women, and improved accessibility to health facilities. Additionally, EMTS need to receive proper education and training for ambulance deliveries. Enhancing ambulance services and supporting EMTs in dealing with litigation claims are also critical.

Use of artificial intelligence to support prehospital traumatic injury care: A scoping review.

Background: Artificial intelligence (AI) has transformative potential to support prehospital clinicians, emergency physicians, and trauma surgeons in acute traumatic injury care. This scoping review examines the literature evaluating AI models using prehospital features to support early traumatic injury care. Methods: We conducted a systematic search in August 2023 of PubMed, Embase, and Web of Science. Two independent reviewers screened titles/abstracts, with a third reviewer for adjudication, followed by a full-text analysis. We included original research and conference presentations evaluating AI models-machine learning (ML), deep learning (DL), and natural language processing (NLP)-that used prehospital features or features available immediately upon emergency department arrival. Review articles were excluded. The same investigators extracted data and systematically categorized outcomes to ensure consistency and transparency. We calculated kappa for interrater reliability and descriptive statistics. Results: We identified 1050 unique publications, with 49 meeting inclusion criteria after title and abstract review (kappa 0.58) and full-text review. Publications increased annually from 2 in 2007 to 10 in 2022. Geographic analysis revealed a 61% focus on data from the United States. Studies were predominantly retrospective (88%), used local (45%) or national level (41%) data, focused on adults only (59%) or did not specify adults or pediatrics (27%), and 57% encompassed both blunt and penetrating injury mechanisms. The majority used machine learning (88%) alone or in conjunction with DL or NLP, and the top three algorithms used were support vector machine, logistic regression, and random forest. The most common study objectives were to predict the need for critical care and life-saving interventions (29%), assist in triage (22%), and predict survival (20%). Conclusions: A small but growing body of literature described AI models based on prehospital features that may support decisions made by dispatchers, Emergency Medical Services clinicians, and trauma teams in early traumatic injury care.

Project RESPOND: Development of a New Capacity in Disaster Response.

Response to the coronavirus disease (COVID-19) pandemic revealed gaps in medical supply quality and personnel training and familiarity in San Francisco County, prompting the reexamination of county disaster supply caches and emergency medical services (EMS) system decompression protocols. Project RESPOND (Rapid Emergency Supplies for Prehospital Operations in Disaster) was developed to bridge the gap in patient care infrastructure during short- or no-warning disasters and enhance EMS system offloading by introducing a novel capacity for the safe treatment and discharge of patients with minor injuries from the scene of an event. This design, while scaled to the needs of a unique metropolitan population, can be used as a template for the reimagining of disaster response policy and development of disaster supply caches.

Disparities in Emergency Medical Services Use, Prehospital Notification, and Symptom Onset to Arrival in Patients With Acute Stroke.

BACKGROUND: Disparities in time to hospital presentation and prehospital stroke care may be important drivers in inequities in acute stroke treatment rates, functional outcomes, and mortality. It is unknown how patient-level factors, such as race and ethnicity and county-level socioeconomic status, affect these aspects of prehospital stroke care. METHODS: Cross-sectional study of patients with ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage in the Get With the Guidelines-Stroke registry, presenting from July 2015 to December 2019, with symptom onset <24 hours. Multivariable logistic regression and quantile regression were used to investigate the outcomes of interest: emergency medical services (EMS) transport (versus private vehicle), EMS prehospital notification (versus no prehospital notification), and stroke symptom onset to time of arrival at the emergency department. Prespecified covariates included patient-level, hospital-level, and county-level characteristics. RESULTS: The inclusion criteria was met by the 606 369 patients. Of the patients, 51.2% were men and 69.9% White, with a median National Institutes of Health Stroke Severity of 4 (IQR, 2-10), and median social deprivation index (SDI) of 51 (IQR, 27-75). Median symptom onset to arrival time was 176 minutes (IQR, 64-565). Black race was significantly associated with prolonged symptom onset to emergency department arrival time (+28.21 minutes [95% CI, 25.59-30.84]), and decreased odds of EMS prehospital notification (OR, 0.80 [95% CI, 0.78-0.82]). SDI was not associated with differences in EMS use but was associated with lower odds of EMS prehospital notification (upper SDI tercile versus lowest, OR, 0.79 [95% CI, 0.78-0.81]). SDI was also significantly associated with stroke symptom onset to emergency department arrival time (upper SDI tercile versus lowest +2.56 minutes [95% CI, 0.58-4.53]). CONCLUSIONS: In this national cross-sectional study, Black race was associated with prolonged onset to time of arrival intervals and significantly decreased odds of EMS prehospital notification, despite similar use of EMS transport. Greater county-level deprivation was also associated with reduced odds of EMS prehospital notification and slightly prolonged stroke symptom onset to emergency department arrival time. Efforts to reduce place-based disparities in stroke care must address significant inequities in prehospital care of acute stroke and continue to address health inequities associated with race and ethnicity.

Disabilities and medical emergencies: a population-based study in Peru. / Discapacidad y urgencias médicas: análisis de una base poblacional peruana.

OBJECTIVE: To estimate the association between disability and the demand for medical emergency care by citizens of Peru over the age of 18 years in 2019. METHODS: Cross-sectional analysis of secondary data from the national survey of budgeted programs (ENAPRES, in its Peruvian abbreviation) of 2019. Disabilities were surveyed based on the criteria of the Washington Group on Disability Statistics. Medical emergencies were queried using 2 questions referring to life-threatening situations. Sociodemographic covariables and variables related to certain medical emergencies were also analyzed as possible confounders. Poisson regression analysis was carried out and crude and adjusted prevalence ratios calculated. Calculations were performed on a complex sample of data from the ENAPRES 2019 survey. RESULTS: Data for 62 959 persons over the age of 18 years were included. Some type of disability was reported by 4.3% of the sample, and 8.7% reported a medical emergency during the past year. Persons with 3 or more disabilities were 2.97-fold more likely to have a medical emergency than persons without disabilities (prevalence ratio, 2.97 (95% CI, 2.28-3.87) after adjustment for multiple confounding variables. CONCLUSIONS: Disabled persons were more likely to have medical emergencies than persons without disabilities in Peru in 2019. The likelihood of medical emergencies was slightly higher in those with 3 or more disabilities.

OBJETIVO: Estimar la asociación entre la condición de discapacidad y la demanda de urgencias médicas en los ciudadanos peruanos mayores de 18 años durante el año 2019. METODO: Se realizó un estudio transversal analítico de datos secundarios de la Encuesta Nacional de Programas Presupuestales (ENAPRES) 2019. La discapacidad se determinó con las preguntas del grupo de Washington y la demanda de urgencias médicas se evaluó con dos preguntas referidas a situaciones que ponen en riesgo la vida de las personas. Se incluyeron covariables sociodemográficas y relacionadas con las urgencias médicas, como posibles confusores. Se llevó a cabo una regresión de Poisson y se estimaron razones de prevalencia (RP) crudas y ajustadas. Todos los cálculos se hicieron de acuerdo con el muestreo complejo de la ENAPRES 2019. RESULTADOS: Se incluyeron los datos de 62.959 personas mayores de 18 años. El 4,3% tenía algún tipo de discapacidad y el 8,7% tuvo una urgencia médica en el último año. Las personas con tres o más tipos de discapacidad tuvieron 2,97 veces más probabilidades de tener una urgencia médica, en comparación con las personas sin discapacidad [RP = 2,97 (IC 95%: 2,28-3,87)], ajustado por múltiples variables de confusión. CONCLUSIONES: En el Perú, durante el año 2019, las personas con discapacidad tuvieron más probabilidades de tener una urgencia médica en comparación con las personas sin discapacidad. Estas probabilidades fueron ligeramente mayores cuando las personas tenían tres o más discapacidades.

Exploring the challenges of emergency medical service providers in the initial phase of the COVID-19 pandemic: a qualitative content analysis.

BACKGROUND: As the COVID-19 pandemic continues to unfold, there has been a substantial increase in the demand for prehospital services. Emergency medical service (EMS) providers have encountered a myriad of challenges that have had a discernible impact on their professional performance. This study was designed to explore the challenges faced by EMS providers during the initial phase of the COVID-19 pandemic. METHODS: This qualitative research was conducted using a content analysis approach at emergency medical centers affiliated with Hamadan University of Medical Sciences in Iran between April and August 2021. This study included the participation of 21 EMS personnel, which was conducted using purposive sampling and semistructured interviews, and continued until data saturation was reached. The conventional content analysis method, as outlined by Graneheim and Lundman, was applied for data analysis. RESULTS: The analysis of the interview data resulted in the identification of 219 primary codes, which were then organized into ten distinct categories. These categories were further consolidated into three overarching themes: personal safety challenges, professional-organizational challenges, and threatened mental health. CONCLUSIONS: EMS personnel play a critical role in healthcare during disasters and pandemics, facing challenges that can have negative effects. Managing these challenges can impact mental health and professional well-being, but awareness, support, resources, and services can help mitigate adverse consequences.

Violent encounters on the front line: Sequential explanatory mixed-methods investigation of physical violence factors in the prehospital setting.

OBJECTIVE: Workplace violence (WPV) is an important issue in prehospital care, especially for emergency medical technicians ( EMTs) who are at increased risk of physical violence due to the nature of their work. This study aimed to shed light on the specific factors that contribute to the underlying causes of physical WPV in the prehospital context through direct experience and insight into the work of EMTs. METHODS: Sequential explanatory mixed methods were applied in five western provinces of Iran from 2022 to 2023. In total, 358 EMTs that met the criteria for the quantitative phase were selected using a multi-stage clustering method. In the quantitative phase, the researchers used a questionnaire on workplace violence in the healthcare sector. Based on the results of the quantitative phase, 21 technicians who had experienced physical violence in the past 12 months were invited for in-depth interviews in the qualitative phase. RESULTS: The average age of the EMTs was 33.96 ± 6.86 years, with an average work experience of 10.57 ± 6.80 years. More than half (53.6%) of the staff worked 24-hour shifts. In addition, most EMTs were located in urban bases (50.3%), and 78 (21.8%) reported having experienced physical violence. No significant correlations were found between the demographic characteristics of the technicians and the frequency of physical violence, except base location in the last 6 months. The qualitative study also created one theme (the complexity of WPV in the prehospital setting), four categories, and ten subcategories. CONCLUSION: The study's results emphasize the need for comprehensive WPV factors in the prehospital setting. These factors can lead to identifying and improving strategies such as organizational support, improving communication and collaboration between responders, and training in de-escalation techniques. In addition, it is crucial to address the root causes of WPV such as poverty and lack of education in the community to create a safer and more supportive environment for patients and staff.

Influence of patient body weight on the probability of return of spontaneous circulation following out-of-hospital cardiac arrest: an exploratory analysis.

Introduction: In addition to key interventions, including bystander CPR and defibrillation, successful resuscitation of out-of-hospital cardiac arrest (OHCA) is also associated with several patient-level factors, including a shockable presenting rhythm, younger age, Caucasian race and female sex. An additional patient-level factor that may influence outcomes is patient weight, yet this attribute has not been extensively studied within the context of OHCA, despite globally increasing obesity rates. Objective: To assess the relationship between patient weight and return of spontaneous circulation (ROSC) during OHCA. Methods: This retrospective study included adult patients from a national emergency medical services (EMS) patient record, with witnessed, non-traumatic OHCA prior to EMS arrival from January to December 2020. Logistic regression was used to evaluate the relationship between patient weight and ROSC. Results: Complete records were available for 9096 patients, of which 64.3% were males and 25.3% were ethnic minorities. The mean age of the participants was 65.01 years (SD = 15.8), with a mean weight of 93.52 kg (SD = 31.5). Altogether, 81.8% of arrests were of presumed cardiac aetiology and 30.3% presented with a shockable rhythm. Bystander CPR and automated external defibrillator (AED) shock were performed in 30.6% and 7.3% of cases, respectively, and 44.0% experienced ROSC. ROSC was less likely with patient weight >100 kg (OR = 0.709, p <0.001), male sex (OR = 0.782, p <0.001), and increasing age and EMS response time (OR = 0.994 per year, p <0.001 and OR = 0.970 per minute, p <0.001, respectively). Patients with shockable rhythms were more likely to achieve ROSC (OR = 1.790, p <0.001), as were patients receiving bystander CPR (OR = 1.170, p <0.001) and defibrillation prior to EMS arrival (OR = 1.658, p <0.001). Although the mean first adrenaline dose (mg/kg) followed a downward trend due to its non-weight-based dosing scheme, the mean total adrenaline dose administered to achieve ROSC demonstrated an upward linear trend of 0.05 mg for every 5 kg of body weight. Conclusions: Patient weight was negatively associated with ROSC and positively associated with the total adrenaline dose required to attain ROSC.
