Bridging the procedures skill gap from medical school to residency: a simulation-based mastery learning curriculum.

BACKGROUND: The transition from medical student to intern is a recognized educational gap. To help address this, the Association of American Medical Colleges developed the Core Entrustable Professional Activities for entering residency. As these metrics outline expectations for all graduating students regardless of specialty, the described procedural expectations are appropriately basic. However, in procedure-heavy specialties such as emergency medicine, the ability to perform advanced procedures continues to contribute to the disconnect between undergraduate and graduate medical education. To prepare our graduating students for their internship in emergency medicine, we developed a simulation-based mastery learning curriculum housed within a specialty-specific program. Our overall goal was to develop the students' procedural competency for central venous catheter placement and endotracheal intubation before graduation from medical school. METHODS: Twenty-five students participated in a simulation-based mastery learning procedures curriculum for ultrasound-guided internal jugular central venous catheter placement and endotracheal intubation. Students underwent baseline assessment, deliberate practice, and post-test assessments. Both the baseline and post-test assessments used the same internally developed checklists with pre-established minimum passing scores. RESULTS: Despite completing an emergency medicine rotation and a critical care rotation, none of the students met the competency standard during their baseline assessments. All twenty-five students demonstrated competency on both procedures by the end of the curriculum. A second post-test was required to demonstrate achievement of the central venous catheter and endotracheal intubation minimum passing scores by 16% and 28% of students, respectively. CONCLUSIONS: Students demonstrated procedural competency for central venous catheter placement and endotracheal intubation by engaging in simulation-based mastery learning procedures curriculum as they completed their medical school training. With three instructional hours, students were able to achieve basic procedural competence for two common, high-risk procedures they will need to perform during emergency medicine residency training.

Layperson-Administered Naloxone Trends Reported in Emergency Medical Service Activations, 2020-2022.

Importance: Layperson-administered naloxone (LAN) is a powerful but incompletely characterized intervention to prevent opioid-related overdose mortality. LAN trends are relevant to policy and strategic planning in naloxone distribution initiatives. Objective: To assess the 2-year LAN trend for persons in the United States receiving naloxone during emergency medical services (EMS) activations. Design, Setting, and Participants: This retrospective cross-sectional study was conducted in the United States from June 2020 to June 2022 among 65 621 195 EMS activations from 911 responses, EMS standbys, or when EMS crews functioned in an ambulance intercept role or during mutual aid to another ambulance response. Activations within health care settings and interfacility or medical transports were excluded. Data are from the National Emergency Medical Services Information System (NEMSIS), the national EMS patient care record database. From June 2020 to June 2022, NEMSIS included more than 96 million EMS activations from nearly 14 000 agencies across 54 states and territories. Exposures: EMS clinician-reported LAN. Main Outcome and Measures: The primary outcome was the trend of receiving LAN, measured by EMS clinician documentation. Results: From June 2020 to June 2022, EMS reported 744 078 patients receiving naloxone, with 24 990 (3.4%) involving LAN. Patients were predominantly male (17 331 [69.4%]) and had a median (IQR) age of 42 (31-56) years, with the majority treated in urban homes or residences (21 692 [86.8%] urban; 13 223 [52.9%] in-home or residence). Of the total naloxone recipients, 243 985 patients (32.8%) had suspected drug overdose documentation as either the primary or secondary impression. Overall, the percentage change in naloxone administration rates decreased 6.1% over the study period (from 1140.1 [95% CI, 1135.1-1145.1] per 100 000 EMS activations to 1070.1 [95% CI, 1064.9-1075.3] per 100 000 EMS activations), while the percentage change of persons receiving LAN increased 43.5% (from 30.0 [95% CI, 29.2-30.8] per 100 000 EMS activations to 43.1 [95% CI, 42.0-44.1] per 100 000 EMS activations). Conclusions and Relevance: In this cross-sectional study, the LAN rate increased from June 2020 to June 2022 as reported in the national EMS database. These findings help inform policies and practices aimed at mitigating the devastating impacts of the opioid epidemic and saving lives. Novel public health strategies are needed to measure the effects of this intervention nationally, evaluate approaches to expand naloxone distribution, and address naloxone usage barriers.

Learner evaluation of an immersive virtual reality mass casualty incident simulator for triage training.

Background: To minimize loss of life, modern mass casualty response requires swift identification, efficient triage categorization, and rapid hemorrhage control. Current training methods remain suboptimal. Our objective was to train first responders to triage a mass casualty incident using Virtual Reality (VR) simulation and obtain their impressions of the training's quality and effectiveness.We trained subjects in a triage protocol called Sort, Assess, Lifesaving interventions, and Treatment and/or Transport (SALT) Triage then had them respond to a terrorist bombing of a subway station using a fully immersive virtual reality simulation. We gathered learner reactions to their virtual reality experience and post-encounter debriefing with a custom electronic survey. The survey was designed to gather information about participants' demographics and prior experience, including roles, triage training, and virtual reality experience. We then asked them to evaluate the training and encounter and the system's potential for training others. Results: We received 375 completed evaluation surveys from subjects who experienced the virtual reality encounter. Subjects were primarily paramedics, but also included medical learners as well as other emergency medical service (EMS) professionals. Most participants (95%) recommended the experience for other first responders and rated the simulation (95%) and virtual patients (91%) as realistic. Ninety-four percent (94%) of participants rated the virtual reality simulator as "excellent" or "good." We observed some differences between emergency medical service and medical professionals regarding their prior experience with disaster response training and their opinions on how much the experience contributed to their learning. We observed no differences between subjects with extensive virtual reality experience and those without. Conclusions: Our virtual reality simulator is an automated, customizable, fully immersive virtual reality system for training and assessing personnel in the proper response to a mass casualty incident. Participants perceived the simulator as an adequate alternative to traditional triage and treatment training and believed that the simulator was realistic and effective for training. Prior experience with virtual reality was not a prerequisite for the use of this system.

Evaluating the Application of an EMS Clinical Judgment Theoretical Framework.

OBJECTIVES: Clinical judgment (CJ) encompasses clinical reasoning (process of evaluating a problem) and clinical decision-making (choice made). A theoretical model to better define emergency medical services (EMS) CJ has been developed but its use has not been evaluated in EMS training and assessments. Our objective was to evaluate the performance of this EMS CJ model to assess clinical reasoning and decision-making in a simulated environment. METHODS: In this evaluation, EMS clinician teams (2-3 members) were directed to care for a simulated older adult patient in their home following a fall. Simulations were video recorded, clinician team actions coded, and evaluated for whether proper CJ reasoning and decisions were made. We evaluated CJ in two ways: 1) EMS medical directors' (MD) determination of whether the CJ questions were addressed (MD score) and 2) objective rubric evaluation of CJ questions using the EMS CJ model focused on recognition of appropriate cues, performance of actions, and revaluation after action (rubric score). The CJ questions addressed in this simulation included: 1) Is the patient stable/unstable?, 2) Are interventions necessary before movement?, 3) How should the patient be transferred from the floor?, and 4) Does the cause of the fall require hospital evaluation? Descriptive statistics were calculated, and concordance between the two assessments was evaluated (mean, 95% CI). Percent concordance was calculated with a validity threshold set at 70%. RESULTS: Four EMS MDs reviewed 20 videos addressing 80 clinical judgment decisions. Overall concordance between MD score and rubric score for CJ decisions was above the threshold at 88.1% (85.0, 91.2). Concordance between MD score and rubric score for each CJ decision was 92.0% (87.3, 96.7) for question 1, 79.9% (71.5, 88.3) for question 2, 95.0% (90.4, 99.6) for question 3, and 85.4% (79.5, 91.2) for question 4. CONCLUSION: An objective evaluation of CJ decisions using a rubric derived from an EMS CJ theoretical framework demonstrated high concordance to subjective evaluations of CJ made by EMS MDs. This approach may allow for reproducible and objective CJ evaluations that could be used for competency assessment in EMS.

Clinical Judgment Item Development for Emergency Medical Service Clinicians.

OBJECTIVES: While clinical judgment is vital for all clinicians, it is not clearly assessed in initial or continuing emergency medical services (EMS) education due to unclear definitions. Recently, clarity of this concept has been provided through the development of a theoretical framework for clinical judgment in EMS that considers the broad and evolving nature of prehospital care delivery. To facilitate standardization of clinical judgment assessments, in this educational practice review we present a template for item development leveraging the new framework. METHODS: We developed this template with input from EMS clinicians, educators, and subject matter experts from the nursing field with experience in clinical judgment item development. This template includes the basic cognitive steps of EMS clinical judgment, including recognizing cues, analyzing cues, defining a hypothesis, generating solutions, taking action, and evaluating the outcomes of those actions. RESULTS: We provide a transparent and reproducible template for item generation for clinical judgment assessments evaluating the six basic cognitive reasoning steps. Further, we provide a fully developed example of template application using a hypoglycemic patient case. This template can be used to support item generation for specific event phases (e.g., en route, scene, and post scene) in a clinical scenario. CONCLUSIONS: This template allows for generation of items for each EMS event phase that can be repeated serially for any combination of prehospital clinical situations.

COVID-19 and coworker conflict among emergency medical service clinicians.

Objectives: Safety policies enacted in response to the emergence of coronavirus disease 2019 (COVID-19) have greatly affected the working environments of emergency medical service (EMS) clinicians. Our objective was to evaluate whether changes in the EMS environment during the COVID-19 pandemic were associated with increased workplace conflict. Methods: This evaluation was a cross-sectional analysis of a random sample of 19,497 national certified EMS clinicians who were selected to receive an electronic survey in April 2022. The survey included an assessment of their level of stress using the Perceived Stress Scale instrument and examined changes in their working environment they perceived had occurred due to the emergence of COVID-19. Logistic regression modeling was used to evaluate the associations between workforce demographics, infrastructure, scheduling, and policies to and COVID-19-induced coworker conflict. Results: A total of 1686 responses were evaluated (response rate 10%). We found that COVID-19 was reported to have exacerbated conflict between coworkers in 51% of responses. Respondents who perceived an increase in coworker conflict due to COVID-19 self-reported higher levels of stress than the rest of the respondents. Perceptions of the impact of COVID-19 on conflict had also an association with the level of certification, indicating that national registered paramedics were more likely than emergency medical technicians to report coworker conflict due to COVID-19 (adjusted odds ratio [AOR] 1.30, 95% confidence interval [CI] 1.05-1.61). Multivariable analysis highlighted the impact of mandatory overtime policies, reported by 27% of the respondents and associated with higher odds of exacerbated coworker conflict in our model (AOR 2.05, 95% CI 1.62-2.60). Conclusions: These findings indicate that conflict can be considered a potential indicator of high levels of stress in the EMS workforce and may be a reliable signal to monitor when implementing mandates that affect EMS clinicians and their workloads.

Management of Patients With Cardiac Arrest Requiring Interfacility Transport: A Scientific Statement From the American Heart Association.

People who experience out-of-hospital cardiac arrest often require care at a regional center for continued treatment after resuscitation, but many do not initially present to the hospital where they will be admitted. For patients who require interfacility transport after cardiac arrest, the decision to transfer between centers is complex and often based on individual clinical characteristics, resources at the presenting hospital, and available transport resources. Once the decision has been made to transfer a patient after cardiac arrest, there is little direct guidance on how best to provide interfacility transport. Accepting centers depend on transferring emergency departments and emergency medical services professionals to make important and nuanced decisions about postresuscitation care that may determine the efficacy of future treatments. The consequences of early care are greater when transport delays occur, which is common in rural areas or due to inclement weather. Challenges of providing interfacility transfer services for patients who have experienced cardiac arrest include varying expertise of clinicians, differing resources available to them, and nonstandardized communication between transferring and receiving centers. Although many aspects of care are insufficiently studied to determine implications for specific out-of-hospital treatment on outcomes, a general approach of maintaining otherwise recommended postresuscitation care during interfacility transfer is reasonable. This includes close attention to airway, vascular access, ventilator management, sedation, cardiopulmonary monitoring, antiarrhythmic treatments, blood pressure control, temperature control, and metabolic management. Patient stability for transfer, equity and inclusion, and communication also must be considered. Many of these aspects can be delivered by protocol-driven care.

Longitudinal Changes in Emergency Medical Services Advanced Airway Management.

Importance: Identifying longitudinal changes in advanced airway management by emergency medical services (EMS) is crucial for understanding practice patterns and optimizing care. Objective: To examine the longitudinal trends in endotracheal intubation (ETI) and supraglottic airway (SGA) utilization in a national EMS cohort. Design, Setting, and Participants: This retrospective cross-sectional study analyzed 2011 to 2022 data from the ESO Data Collaborative, a national database of US prehospital electronic health records. The study included all 911 EMS events in which advanced airway management was attempted. Data were analyzed from November 2022 to January 2024. Exposures: Advanced airway management attempts, including ETI, SGA, and surgical airways. Main Outcomes and Measures: The annual percentage of ETI and SGA attempts, stratified by underlying condition (cardiac arrest, nonarrest medical, nonarrest trauma, pediatrics). Results: Among 47.5 million EMS activations, 444 041 (mean [SD] age, 60.6 [19.8] years; 273 296 [61.5%] men) involved advanced airway management, including 305 584 (68.8%) that used ETI and 200 437 (45.1%) that used SGA. The overall incidence was 9.3 per 1000 EMS events. In the cardiac arrest cohort from 2011 to 2022, EMS events with ETI attempts decreased from 2470 of 2831 (87.3%) to 40 083 of 72 793 (55.1%) and those with SGA attempts increased from 711 of 2831 (25.1%) to 44 386 of 72 793 (61.0%). In the pediatric subset, there were similarly large decreases in ETI attempts, from 117 of 182 EMS events (97.3%) to 1573 of 2307 EMS events (68.2%), and increases in SGA attempts, from 11 of 182 EMS events (6.6%) to 1058 of 2307 EMS events (45.9%). In the nonarrest medical and nonarrest trauma cohorts, ETI attempts decreased and SGA attempts increased but to a much lower extent. Conclusions and Relevance: In this national cross-sectional study of EMS care episodes, there were marked shifts in advanced airway management practices, with the increased use of SGA and decreased use of ETI. These observations highlight current trends in EMS airway management practices.

Temporal Trends in End-Tidal Capnography and Outcomes in Out-of-Hospital Cardiac Arrest: A Secondary Analysis of a Randomized Clinical Trial.

Importance: While widely measured, the time-varying association between exhaled end-tidal carbon dioxide (EtCO2) and out-of-hospital cardiac arrest (OHCA) outcomes is unclear. Objective: To evaluate temporal associations between EtCO2 and return of spontaneous circulation (ROSC) in the Pragmatic Airway Resuscitation Trial (PART). Design, Setting, and Participants: This study was a secondary analysis of a cluster randomized trial performed at multicenter emergency medical services agencies from the Resuscitation Outcomes Consortium. PART enrolled 3004 adults (aged ≥18 years) with nontraumatic OHCA from December 1, 2015, to November 4, 2017. EtCO2 was available in 1172 cases for this analysis performed in June 2023. Interventions: PART evaluated the effect of laryngeal tube vs endotracheal intubation on 72-hour survival. Emergency medical services agencies collected continuous EtCO2 recordings using standard monitors, and this secondary analysis identified maximal EtCO2 values per ventilation and determined mean EtCO2 in 1-minute epochs using previously validated automated signal processing. All advanced airway cases with greater than 50% interpretable EtCO2 signal were included, and the slope of EtCO2 change over resuscitation was calculated. Main Outcomes and Measures: The primary outcome was ROSC determined by prehospital or emergency department palpable pulses. EtCO2 values were compared at discrete time points using Mann-Whitney test, and temporal trends in EtCO2 were compared using Cochran-Armitage test of trend. Multivariable logistic regression was performed, adjusting for Utstein criteria and EtCO2 slope. Results: Among 1113 patients included in the study, 694 (62.4%) were male; 285 (25.6%) were Black or African American, 592 (53.2%) were White, and 236 (21.2%) were another race; and the median (IQR) age was 64 (52-75) years. Cardiac arrest was most commonly unwitnessed (n = 579 [52.0%]), nonshockable (n = 941 [84.6%]), and nonpublic (n = 999 [89.8%]). There were 198 patients (17.8%) with ROSC and 915 (82.2%) without ROSC. Median EtCO2 values between ROSC and non-ROSC cases were significantly different at 10 minutes (39.8 [IQR, 27.1-56.4] mm Hg vs 26.1 [IQR, 14.9-39.0] mm Hg; P < .001) and 5 minutes (43.0 [IQR, 28.1-55.8] mm Hg vs 25.0 [IQR, 13.3-37.4] mm Hg; P < .001) prior to end of resuscitation. In ROSC cases, median EtCO2 increased from 30.5 (IQR, 22.4-54.2) mm HG to 43.0 (IQR, 28.1-55.8) mm Hg (P for trend < .001). In non-ROSC cases, EtCO2 declined from 30.8 (IQR, 18.2-43.8) mm Hg to 22.5 (IQR, 12.8-35.4) mm Hg (P for trend < .001). Using adjusted multivariable logistic regression with slope of EtCO2, the temporal change in EtCO2 was associated with ROSC (odds ratio, 1.45 [95% CI, 1.31-1.61]). Conclusions and Relevance: In this secondary analysis of the PART trial, temporal increases in EtCO2 were associated with increased odds of ROSC. These results suggest value in leveraging continuous waveform capnography during OHCA resuscitation. Trial Registration: ClinicalTrials.gov Identifier: NCT02419573.

State-Based Evaluation of the Workforce Pipeline from Paramedic Program Enrollment to Agency Affiliation.

OBJECTIVES: The strength and stability of the paramedic workforce is dependent on the continual flow of EMS clinicians into the field. Workforce entry requires three distinct steps: program completion, certification attainment, and affiliation with an EMS agency. At each of these steps, future EMS clinicians may be lost to the workforce but the contribution of each is unknown. Our objective was to evaluate these inflection points using a state-based registry of EMS clinicians from their point of entry into the EMS education system to eventual EMS agency affiliation. METHODS: This is a retrospective cohort evaluation of paramedic students in the Commonwealth of Virginia. We included any student who enrolled in a paramedic program in 2017 or 2018. Data were provided by the Virginia Office of Emergency Medical Services, who tracks the development of EMS clinicians from the point of entry into an educational program through their affiliation with an EMS agency upon employment. Our primary outcomes include proportions of enrolled students who complete a program, graduating students who attain national/state certification, and nationally certified EMS clinicians who affiliate with an EMS agency. Proportions were calculated at each step and compared to the overall population of students enrolled. RESULTS: In 2017 and 2018, 775 and 603 students were enrolled in paramedic programs, respectively. Approximately a quarter of students did not complete their paramedic program (2017: 25% [192/775]; 2018: 28% [170/603]). Of those who graduated, the proportion of students not gaining certification was lower (2017: 11% [62/583]; 2018: 17% [75/433]). Of those who certified, those not affiliating was similarly low (2017: 15% [77/521]; 2018: 13% [46/358]). Evaluating the effect of each of these steps on the total entry into the workforce, nearly half of those who originally enrolled did not join the workforce through agency affiliation (2017: 43% [331/775]; 2018: 48% [291/603]). CONCLUSIONS: There are multiple areas to enhance retention of potential EMS trainees from program enrollment to EMS agency affiliation. This analysis suggests that educational attrition has a larger impact on the availability of new paramedics than certification examinations or agency affiliation decisions, though is limited to a singular state evaluation.

Examining the Reliability and Validity of the ALS Certification Examinations with the Inclusion of Clinical Judgment: An Update on the ALS Examination Redesign.

OBJECTIVES: Clinical judgment describes the process an emergency medical service clinician uses to evaluate problems and make decisions in the out-of-hospital setting. As part of the redesign of the Advanced Life Support (ALS) certification examinations, the National Registry of Emergency Medical Technicians is developing and evaluating items that measure clinical judgment, with the intention of assessing these as a new domain in the ALS certification examinations. In this study, we provide evidence around the redesign by evaluating the reliability and validity of the advanced emergency medical technician (AEMT) and paramedic certification examinations when clinical judgment is included as a sixth domain along with the five current domains. METHODS: Pretest (i.e., pilot, unscored) clinical judgment items were included as a new sixth clinical judgment domain. We then used the combination of operational (i.e., scored) and pretest items for all six domains and scored the redesigned AEMT and paramedic certification examinations. We evaluated the psychometric properties of these ALS examinations within the Rasch measurement framework with multiple assessments of reliability and validity including item-level statistics (e.g., mean-square infit and outfit, local dependence) and examination-level statistics (e.g., person reliability, item reliability, item separation, decision consistency, decision accuracy). Wright Maps were produced to evaluate whether the examination item difficulty statistics aligned with the candidate ability continuum. RESULTS: The total population of all examination forms included were 20,136 (AEMT 4,983; paramedic 15,153). The Rasch-based statistics for the redesigned AEMT and paramedic examinations, for both item and examination-level statistics, were well within the psychometric standard values. Wright maps demonstrated that the developed items fall along the candidate ability continuum for both examinations. Further, the distribution of clinical judgment item difficulties fell within the current item distribution, providing evidence that these new items are of similar difficulty to the items measuring the five current domains. CONCLUSION: We demonstrate strong reliability and validity evidence to support that the integrity of the examinations is upheld with the addition of clinical judgment items, while also providing a more robust candidate evaluation. Most importantly, the pass/fail decisions that candidates receive accurately reflect their level of ALS knowledge at the entry-level.

Preparing interns for clinical practice through an institution-wide simulation-based mastery learning program for teaching central venous catheter placement.

Central venous catheter (CVC) placement is a challenging procedure with known iatrogenic risks. However, there are no residency program requirements to demonstrate baseline CVC procedural competency. Competency-based procedural education has been shown to decrease CVC-associated morbidity, but there has been limited literature about institution-wide efforts to ensure initial trainee competency for CVC placement. This study describes the implementation of a competency-based CVC curriculum for first-year interns across an institution before supervised clinical care. An institution-wide, simulation-based mastery training curriculum was designed to assess initial competency in CVC placement in first-year residents during 2021 and 2022. A checklist was internally developed with a multidisciplinary team. Using the Mastery-Angoff technique, minimum passing standards were derived to define competency levels considered appropriate for intern participation in supervised clinical care. Interns were trained through the competency-based program with faculty assessing intern performance using the CVC checklist to verify procedural competency. Over 2 academic cycles, 229 interns from 20 specialties/subspecialties participated. Overall, 83% of interns met performance standards on their first posttest attempt, 14% on the second attempt, and 3% on the third attempt. Interns from both cycles demonstrated significant improvement from baseline to posttest scores (P < .001). Overall, 10.5% of interns performed dangerous actions during assessment (malpositioning, retained guidewire, or carotid dilation). All interns ultimately achieved the passing standard to demonstrate initial competency in the simulation assessment. All participating interns demonstrated simulation-based competency allowing them to place CVCs under supervised clinical care. Dangerous actions, however, were not uncommon. Simulation-based teaching and learning frameworks were a feasible method to promote patient safety through an institutional-wide verification of preliminary procedural competency.

Emergency Medical Services and Public Health Perspectives on Alternative Emergency Response Models.

CONTEXT: New approaches to emergency response are a national focus due to evolving needs and growing demands on the system, but perspectives of first responders and potential partners have not been evaluated. OBJECTIVE: This project aimed to inform the development and implementation of alternative emergency response models, including interdisciplinary partnerships, by identifying the perspectives of the frontline workforce regarding their evolving roles. DESIGN: An electronic survey was sent, querying respondents about their perceived roles in emergency response, interdisciplinary partnerships, and resources needed. SETTING: This study took place in a metropolitan, midwestern county with participants from 2 public health agencies and 1 emergency medical services (EMS) agency. PARTICIPANTS: The survey was completed by 945 EMS clinicians and 58 public health workers. MAIN OUTCOME MEASURES: The main outcome measures were agreement levels on each group's roles in prevention, response, and recovery after emergencies, as well as general feedback on new models. RESULTS: Overall, 97% of EMS clinicians and 42% of public health workers agreed that they have a role in immediate response to 9-1-1 emergencies. In mental health emergencies, 87% of EMS clinicians and 52% of public health workers agreed that they have a role, compared to 87% and 30%, respectively, in violent emergencies. Also, 84% of respondents felt multidisciplinary models are a needed change. However, 35% of respondents felt their agency has the resources necessary for changes. CONCLUSIONS: We observed differences between EMS clinicians and public health workers in their perceived roles during emergency response and beliefs about the types of emergencies within their scope. There is strong support for alternative approaches and a perception that this model may improve personal well-being and job satisfaction, but a need for additional resources to develop and implement.

Emergency Medical Service Agency Practices and Cardiac Arrest Survival.

Importance: Survival for out-of-hospital cardiac arrest (OHCA) varies widely across emergency medical service (EMS) agencies in the US. However, little is known about which EMS practices are associated with higher agency-level survival. Objective: To identify resuscitation practices associated with favorable neurological survival for OHCA at EMS agencies. Design, Setting, and Participants: This cohort study surveyed EMS agencies participating in the Cardiac Arrest Registry to Enhance Survival (CARES) with 10 or more OHCAs annually during January 2015 to December 2019; data analyses were performed from April to October 2023. Exposure: Survey of resuscitation practices at EMS agencies. Main Outcomes and Measures: Risk-standardized rates of favorable neurological survival for OHCA at each EMS agency were estimated using hierarchical logistic regression. Multivariable linear regression then examined the association of EMS practices with rates of risk-standardized favorable neurological survival. Results: Of 577 eligible EMS agencies, 470 agencies (81.5%) completed the survey. The mean (SD) rate of risk-standardized favorable neurological survival was 8.1% (1.8%). A total of 7 EMS practices across 3 domains (training, cardiopulmonary resuscitation [CPR], and transport) were associated with higher rates of risk-standardized favorable neurological survival. EMS agencies with higher favorable neurological survival rates were more likely to use simulation to assess CPR competency (ß = 0.54; P = .05), perform frequent reassessment (at least once every 6 months) of CPR competency in new staff (ß = 0.51; P = .04), use full multiperson scenario simulation for ongoing skills training (ß = 0.48; P = .01), perform simulation training at least every 6 months (ß = 0.63; P < .001), and conduct training in the use of mechanical CPR devices at least once annually (ß = 0.43; P = .04). EMS agencies with higher risk-standardized favorable neurological survival were also more likely to use CPR feedback devices (ß = 0.58; P = .007) and to transport patients to a designated cardiac arrest or ST-segment elevation myocardial infarction receiving center (ß = 0.57; P = .003). Adoption of more than half (≥4) of the 7 practices was more common at EMS agencies in the highest quartile of favorable neurological survival rates (70 of 118 agencies [59.3%]) vs the lowest quartile (42 of 118 agencies [35.6%]) (P < .001). Conclusions and Relevance: In a national registry for OHCA, 7 practices associated with higher rates of favorable neurological survival were identified at EMS agencies. Given wide variability in neurological survival across EMS agencies, these findings provide initial insights into EMS practices associated with top-performing EMS agencies in OHCA survival. Future studies are needed to validate these findings and identify best practices for EMS agencies.

Implementation of a workshop for mass casualty incident triage training using an immersive virtual reality simulation.

Objective: We offered a workshop at the 2023 annual meeting of the Society for Academic Emergency Medicine to teach the Sort-Assess-Lifesaving Interventions-Treatment/Transport (SALT) triage protocol for responding to mass casualty incidents (MCIs) using an immersive virtual reality (VR) simulator. Here, we report workshop outcomes. Methods: After a 1-h didactic on the basics of triage protocols, workshop participants rotated through three skill stations at which learners learned how to use the VR headset and controllers, practiced applying SALT triage skills through a tabletop exercise, and then finally used our VR simulator for training responses to MCIs. During their encounter with VR, participants applied their new knowledge to triaging and treating the victims of an explosion in a virtual subway station. After a brief orientation, participants entered the scene to treat and triage virtual patients who had various life-threatening (e.g., acute arterial bleed, penetrating injury, pneumothorax, amputations) and non-life-threatening injuries (lacerations, sprains, hysteria, confusion). The simulator generated a performance report for each workshop attendee to be used for debriefing by a skilled facilitator. Results: Participants were mostly trainees (residents), all of whom properly initiated their encounter with global sort commands (walk and wave) to identify the most critically injured. On average, participants correctly treated 92% of 18 injuries, with all bleeding injuries being properly controlled (tourniquets or wound packing). On average, participants correctly tagged 87.7% of 11 patients, but only took the pulse of 67% of the 11 patients. Learners had difficulty with cases involving embedded shrapnel and properly tagging patients who were stable after treatments. Conclusions: Our VR simulator provided a practical, portable, reproducible training and assessment system for preparing future emergency medical systems (EMS) medical directors to teach their EMS professionals the triage and lifesaving intervention treatment skills needed to save lives.

Clinical duties and compensation for U.S. emergency medicine fellows at academic centers: A descriptive, cross-sectional survey.

Objective: Fellowship training is increasingly popular among residency graduates and critical to the advancement of academic emergency medicine (EM). Little is known about the clinical hours worked and financial compensation received by fellows during training. We sought to describe the clinical duties and financial compensation of EM fellows at U.S. academic centers. Methods: This cross-sectional study surveyed U.S. academic EM department administrators who were members of the Society for Academic Emergency Medicine's Academy of Administrators in Academic Emergency Medicine (AAAEM) regarding their fellowship programs and fellows. We electronically distributed the validated survey instrument to 73 member sites between October 2022 and January 2023. Survey domains included fellow and fellowship demographics, base and total annual clinical hours, and base and total annual compensation. We calculated descriptive statistics and compared fellows by accreditation (Accreditation Council for Graduate Medical Education [ACGME] or non-ACGME) using chi-square and Wilcoxon rank-sum testing. We conducted a secondary analysis of base and total salary by gender and accreditation using Wilcoxon rank-sum testing. Results: We received 38 institutional responses (response rate 52%), which represented 217 individual fellows. Nearly three-fourths (n = 158, 72.8%) of fellows enrolled in non-ACGME fellowships, worked 33% more base hours annually than ACGME fellows (median 571 h vs. 768 h, p < 0.001), and received base compensation 20% higher than ACGME fellows ($88,540 vs. $70,777, p < 0.001). Accounting for additional compensation, the median total annual compensation for non-ACGME fellows remained 11% higher than ACGME fellows ($105,000 vs. $93,853, p = 0.004). We observed no significant differences salary when stratified by gender. Conclusions: Most EM fellows at U.S. academic institutions enrolled in non-ACGME fellowships with significantly higher base hours and financial compensation than ACGME fellowships. These results represent the first description of the clinical hours and financial compensation of academic EM fellows and should be considered in ongoing benchmarking efforts by AAAEM.

Statewide implementation of the cardiac arrest registry to enhance survival in Ohio.

Objective: Public health surveillance is essential for improving community health. The Cardiac Arrest Registry to Enhance Survival (CARES) is a surveillance system for out-of-hospital cardiac arrest (OHCA). We describe results of the organized statewide implementation of Ohio CARES. Methods: We performed a retrospective analysis of CARES enactment in Ohio. Key elements included: establishment of statewide leadership, appointment of a dedicated coordinator, conversion to a statewide subscription, statewide dissemination of information, fundraising from internal and external stakeholders, and conduct of resuscitation academies. We identified all adult (≥18 years) OHCA reported in the registry during 2013-2020. We evaluated OHCA characteristics before (2013-2015) and after (2016-2019) statewide implementation using chi-square test. We evaluated trends in OHCA outcomes using the Cochran-Armitage test of trend. Results: Statewide CARES promotion increased participation from 2 (urban) to 136 (129 urban, 7 rural) EMS agencies. Covered population increased from 1.2 M (10% of state) to 4.8 M (41% of state). After statewide implementation, OHCA populations increased male (58.1% vs 60.8%, p < 0.01), white (50.1% vs 63.7%, p < 0.01), bystander witnessed (26.9% vs 32.9%, p < 0.01) OHCAs. Bystander CPR (34.7% vs 33.2%, p = 0.22), bystander AED (13.5% vs 12.3%, p = 0.55) and initial rhythm (shockable 18.0% vs 18.3%, p = 0.32) did not change. From 2013 to 2019 there were temporal increases in ROSC (29.7% to 31.9%, p-trend = 0.028), survival (7.4% to 12.3%, p-trend < 0.001) and survival with good neurologic outcome (5.6% to 8.6%, p-trend = 0.047). Conclusion: The organized statewide implementation of CARES in Ohio was associated with marked increases in community uptake and concurrent observed improvements in patient outcomes. These results highlight key lessons for community-wide fostering of OHCA surveillance.

Mobile Integrated Health Care Roles of US EMS Clinicians: A Descriptive Cross-Sectional Study.

OBJECTIVE: Mobile integrated health care (MIH) leverages emergency medical services (EMS) clinicians to perform local health care functions. Little is known about the individual EMS clinicians working in this role. We sought to describe the prevalence, demographics, and training of EMS clinicians providing MIH in the United States (US). METHODS: This is a cross-sectional study of US-based, nationally certified civilian EMS clinicians who completed the National Registry of Emergency Medical Technicians (NREMT) recertification application during the 2021-2022 cycle and completed the voluntary workforce survey. Workforce survey respondents self-identified their job roles within EMS, including MIH. If an MIH role was selected, additional questions clarified the primary role in EMS, type of MIH provided, and hours of MIH training received. We merged the workforce survey responses with the individual's NREMT recertification demographic profile. The prevalence of EMS clinicians with MIH roles and data on demographics, clinical care provided, and MIH training were calculated using descriptive statistics, including proportions with associated binomial 95% confidence intervals (CI). RESULTS: Of 38,960 survey responses, 33,335 met inclusion criteria and 490 (1.5%; 95%CI 1.3-1.6%) EMS clinicians indicated MIH roles. Of these, 62.0% (95%CI 57.7-66.3%) provided MIH as their primary EMS role. EMS clinicians with MIH roles were present in all 50 states and certification levels included emergency medical technician (EMT) (42.8%; 95%CI 38.5-47.2%), advanced emergency medical technician (AEMT) (3.5%; 95%CI 1.9-5.1%), and paramedic (53.7%; 95%CI 49.3-58.1%). Over one-third (38.6%; 95%CI 34.3-42.9%) of EMS clinicians with MIH roles received bachelor's degrees or above, and 48.4% (95%CI 43.9%-52.8%) had been in their MIH roles for less than 3 years. Nearly half (45.6%; 95%CI 39.8-51.6%) of all EMS clinicians with primary MIH roles received less than 50 hours (h) of MIH training; only one-third (30.0%; 95%CI 24.7-35.6%) received more than 100 h of training. CONCLUSION: Few nationally certified US EMS clinicians perform MIH roles. Only half of MIH roles were performed by paramedics; EMT and AEMT clinicians performed a substantial proportion of MIH roles. The observed variability in certification and training suggest heterogeneity in preparation and performance of MIH roles among US EMS clinicians.

Medical Directors, Facilities, and Finances: Resource Deficiencies in Accredited Paramedic Programs.

BACKGROUND: Initial paramedic education must have sufficient rigor and appropriate resources to prepare graduates to provide lifesaving prehospital care. Despite required national paramedic accreditation, there is substantial variability in paramedic pass rates that may be related to program infrastructure and clinical support. Our objective was to evaluate US paramedic program resources and identify common deficiencies that may affect program completion. METHODS: We conducted a cross-sectional mixed methods analysis of the 2018 Committee on Accreditation of Educational Programs for the Emergency Medical Services Professions annual report, focusing on program Resource Assessment Matrices (RAM). The RAM is a 360-degree evaluation completed by program personnel, advisory committee members, and currently enrolled students to identify program resource deficiencies affecting educational delivery. The analysis included all paramedic programs that reported graduating students in 2018. Resource deficiencies were categorized into ten categories: faculty, medical director, support personnel, curriculum, financial resources, facilities, clinical resources, field resources, learning resources, and physician interaction. Descriptive statistics of resource deficiency categories were conducted, followed by a thematic analysis of deficiencies to identify commonalities. Themes were generated from evaluating individual deficiencies, paired with program-reported analysis and action plans for each entry. RESULTS: Data from 626 programs were included (response rate = 100%), with 143 programs reporting at least one resource deficiency (23%). A total of 406 deficiencies were identified in the ten categories. The largest categories (n = 406) were medical director (14%), facilities (13%), financial resources (13%), support personnel (11%), and physician interaction (11%). The thematic analysis demonstrated that a lack of medical director engagement in educational activities, inadequate facility resources, and a lack of available financial resources affected the educational environment. Additionally, programs reported poor data collection due to program director turnover. CONCLUSION: Resource deficiencies were frequent for programs graduating paramedic students in 2018. Common themes identified were a need for medical director engagement, facility problems, and financial resources. Considering the pivotal role of EMS physicians in prehospital care, a consistent theme throughout the analysis involved challenges with medical director and physician interactions. Future work is needed to determine best practices for paramedic programs to ensure adequate resource availability for initial paramedic education.
