Association between EMS Workforce Density and Population Health Outcomes in the U.S.

BACKGROUND: The prehospital care provided by emergency medical services (EMS) personnel is a critical component of the public health, public safety, and health care systems in the U.S.; however, the population-level value of EMS care is often overlooked. No studies have examined how the density of EMS personnel relates to population-level health outcomes. Our objectives were to examine the geographic distribution and density of EMS personnel in the U.S.; and quantify the association between EMS personnel density and population-level health outcomes. METHODS: We conducted a cross-sectional evaluation of county-level EMS personnel density using estimates from the National Registry of Emergency Medical Technicians in nine states that require continuous national certification (Alabama, Louisiana, Massachusetts, Minnesota, New Hampshire, North Dakota, South Carolina, Vermont, and Washington, D.C.). Outcomes of interest included life expectancy, all-cause mortality, and cardiac arrest mortality. We used quantile regression models to examine the association between a 10-person increase in EMS personnel density and each outcome at the 10th, 50th (median), and 90th percentiles, controlling for population characteristics and area health resources. RESULTS: There were 356 counties included, with a mean EMS density of 223 EMS personnel per 100,000 population. Density was higher in rural compared to urban counties (247 versus 186 per 100,000 population; p = 0.001). In unadjusted models, there was a significant association between increase in EMS personnel density and an increase in life expectancy at each examined percentile (e.g., 50th percentile, increase of 52.9 days; 95% CI 40.2, 65.5; p < 0.001), decrease in all-cause mortality at each examined percentile, and decrease in cardiac arrest mortality at the 50th and 90th percentiles. These associations were not statistically significant in the adjusted models. CONCLUSIONS: EMS personnel density differs between urban and rural areas, with higher density per population in rural areas. There were no statistically significant associations between EMS density and population-level health outcomes after controlling for population characteristics and other health resources. The best approach to quantifying the community-level value that EMS care may or may not provide remains unclear.

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.

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.

Comparison of the Scope of Practice of the Army Combat Medic Specialist and Civilian National EMS Certification Levels.

INTRODUCTION: The transition of Army Combat Medic Specialists (Military Occupational Specialty Code: 68W) from military to civilian emergency medical services (EMS) is challenging, and the pathway is not clearly defined. Our objective was to evaluate the current military requirements for 68W and how they compare to the 2019 EMS National Scope of Practice Model (SoPM) for the civilian emergency medical technician (EMT) and advanced emergency medical technician (AEMT). METHODS: This was a cross-sectional evaluation of the 68W skill floor as defined by the Soldier's Manual and Trainer's Guide Healthcare Specialist and Medical Education and Demonstration of Individual Competence in comparison to the 2019 SoPM, which categorizes EMS tasks into seven skill categories. Military training documents were reviewed and extracted for specific information on military scope of practice and task-specific training requirements. Descriptive statistics were calculated. RESULTS: Army 68Ws were noted to perform all (59/59) tasks that coincide with the EMT SoPM. Further, Army 68W practiced above scope in the following skill categories: airway/ventilation (3 tasks); medication administration route (7 tasks); medical director approved medication (6 tasks); intravenous initiation maintenance fluids (4 tasks); and miscellaneous (1 task). Army 68W perform 96% (74/77) of tasks aligned with the AEMT SoPM, excluding tracheobronchial suctioning of an intubated patient, end-tidal CO2 monitoring or waveform capnography, and inhaled nitrous oxide monitoring. Additionally, the 68W scope included six tasks that were above the SoPM for AEMT; airway/ventilation (2 tasks); medication administration route (2 tasks); and medical director approved medication (2 tasks). CONCLUSIONS: The scope of practice of U.S. Army 68W Combat Medics aligns well with the civilian 2019 Scope of Practice Model for EMTs and AEMTs. Based on the comparative scope of practice analysis, transitioning from Army 68W Combat Medic to civilian AEMT would require minimal additional training. This represents a promising potential workforce to assist with EMS workforce challenges. Although aligning the scope of practice is a promising first step, future research is needed to assess the relationship of Army 68Ws training with state licensure and certification equivalency to facilitate this transition.

Measuring the Implementation Preferences of Emergency Medical Services Clinicians Using Discrete Choice Experiments.

INTRODUCTION: Prehospital research and evidence-based guidelines (EBGs) have grown in recent decades, yet there is still a paucity of prehospital implementation research. While recent studies have revealed EMS agency leadership perspectives on implementation, the important perspectives and opinions of frontline EMS clinicians regarding implementation have yet to be explored in a systematic approach. The objective of this study was to measure the preferences of EMS clinicians for the process of EBG implementation and whether current agency practices align with those preferences. METHODS: This study was a cross-sectional survey of National Registry of Emergency Medical Technicians registrants. Eligible participants were certified paramedics who were actively practicing EMS clinicians. The survey contained discrete choice experiments (DCEs) for three EBG implementation scenarios and questions about rank order preferences for various aspects of the implementation process. For the DCEs, we used multinomial logistic regression to analyze the implementation preference choices of EMS clinicians, and latent class analysis to classify respondents into groups by their preferences. RESULTS: A total of 183 respondents completed the survey. Respondents had a median age of 39 years, were 74.9% male, 89.6% White, and 93.4% of non-Hispanic ethnicity. For all three DCE scenarios, respondents were significantly more likely to choose options with hospital feedback and individual-level feedback from EMS agencies. Respondents were significantly less likely to choose options with email/online only education, no feedback from hospitals, and no EMS agency feedback to clinicians. In general, respondents' preferences favored classroom-based training over in-person simulation. For all DCE questions, most respondents (66.2%-77.1%) preferred their survey DCE choice to their agency's current implementation practices. In the rank order preferences, most participants selected "knowledge of the underlying evidence behind the change" as the most important component of the process of implementation. CONCLUSIONS: In this study of EMS clinicians' implementation preferences using DCEs, respondents preferred in-person education, feedback on hospital outcomes, and feedback on their individual performance. However, current practice at EMS agencies rarely matched those expressed EMS clinician preferences. Collectively, these results present opportunities for improving EMS implementation from the EMS clinician perspective.

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.

Evidence-Based Guidelines for Prehospital Airway Management: Methods and Resources Document.

INTRODUCTION: Emergency airway management is a common and critical task EMS clinicians perform in the prehospital setting. A new set of evidence-based guidelines (EBG) was developed to assist in prehospital airway management decision-making. We aim to describe the methods used to develop these EBGs. METHODS: The EBG development process leveraged the four key questions from a prior systematic review conducted by the Agency for Healthcare Research and Quality (AHRQ) to develop 22 different population, intervention, comparison, and outcome (PICO) questions. Evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework and tabulated into the summary of findings tables. The technical expert panel then used a rigorous systematic method to generate evidence to decision tables, including leveraging the PanelVoice function of GRADEpro. This process involved a review of the summary of findings tables, asynchronous member judging, and online facilitated panel discussions to generate final consensus-based recommendations. RESULTS: The panel completed the described work product from September 2022 to April 2023. A total of 17 summary of findings tables and 16 evidence to decision tables were generated through this process. For these recommendations, the overall certainty in evidence was "very low" or "low," data for decisions on cost-effectiveness and equity were lacking, and feasibility was rated well across all categories. Based on the evidence, 16 "conditional recommendations" were made, with six PICO questions lacking sufficient evidence to generate recommendations. CONCLUSION: The EBGs for prehospital airway management were developed by leveraging validated techniques, including the GRADE methodology and a rigorous systematic approach to consensus building to identify treatment recommendations. This process allowed the mitigation of many virtual and electronic communication confounders while managing several PICO questions to be evaluated consistently. Recognizing the increased need for rigorous evidence evaluation and recommendation development, this approach allows for transparency in the development processes and may inform future guideline development.

National examination of occupational hazards in emergency medical services.

OBJECTIVE: Emergency medical services (EMS) clinicians operate in environments that predispose them to occupational hazards. Our objective was to evaluate the frequency of occupational hazards and associations with mitigation strategies in a national dataset. METHODS: We performed a cross-sectional analysis of currently working, nationally certified civilian EMS clinicians aged 18-85 in the USA. After recertifying their National EMS Certification, respondents were invited to complete a survey with questions regarding demographics, work experience and occupational hazards. Three multivariable logistic regression models (OR, 95% CI) were used to describe associations between these hazards and demographics, work characteristics and mitigation strategies. Models were adjusted for age, sex, minority status, years of experience, EMS agency type, service type and EMS role. RESULTS: A total of 13 218 respondents met inclusion criteria (response rate=12%). A high percentage of EMS clinicians reported occupational injuries (27%), exposures (38%) and violence (64%) in the past 12 months. Odds of injury were lower with the presence of a lifting policy (0.73, 0.67-0.80), lift training (0.74, 0.67-0.81) and always using a powered stretcher (0.87, 0.78-0.97). Odds of exposure decreased with chemical, biological and nuclear exposure protection training (0.75, 0.69-0.80). Training in de-escalation techniques was associated with lower odds of experiencing violence (0.87, 0.79-0.96). CONCLUSIONS: Occupational hazards are commonly experienced among EMS clinicians. Common mitigation efforts are associated with lower odds of reporting these hazards. Mitigation strategies were not widespread and associated with lower odds of occupational hazards. These findings may present actionable items to reduce occupational hazards for EMS clinicians.

Differences in Characteristics between EMS Clinicians with Patient Care and Non-Patient Care Roles.

OBJECTIVE: Emergency medical services (EMS) play a key role in access to prehospital emergency care. While EMS has defined levels of certification, the roles in the care paradigm fulfilled by these clinicians vary. The aim of this study is to describe the national differences between EMS clinicians with primary non-patient care vs. patient care roles. METHODS: We performed a cross sectional evaluation of nationally certified EMS clinicians in the United States who recertified in 2020. As part of the recertification process, applicants voluntarily complete profile questions regarding demographic, job, and service characteristics. We compared the characteristics between individuals self-reporting primary patient care roles vs. non-patient care roles. Using logistic regression, we determined independent predictors for having a non-patient care role. RESULTS: In 2020, 126,038 people completed recertification. Of the 96,661 completing the profile, 80,591 (83.4%) indicated that they provided patient care, and 16,070 (16.6%) did not provide patient care as a primary role. Non-patient care personnel were more likely to be older (median 43 years old vs 34 years old), and to have a higher level of education (bachelor's degree or more: OR 2.25, 95%CI [2.13-2.38]) compared with patient care practitioners. Non-patient care personnel were less likely to be female (0.67 [0.64-0.70]) and minorities (OR 0.80 [0.76-0.84]). Non-patient care personnel reported longer work experience (16 years or more: OR 6.30 [5.98-6.64]), were less likely to hold part time positions (OR 0.62 [0.59-0.65]), and were less often attached to more than one agency (OR 0.83 [0.79-0.86]). Non-patient care personnel were less likely to work in rural settings (OR 0.81 [0.78-0.85]). CONCLUSIONS: EMS clinicians in non-patient care roles account for 17% of the study population. The odds of performing as a non-patient care practitioner are associated with characteristics related to demographics and workforce experience. Future work will be necessary to identify mechanisms to encourage diversity within the patient care and non-patient care workforces.

Evidence-Based Guidelines for Prehospital Pain Management: Literature and Methods.

INTRODUCTION: Emergency Medical Services (EMS) clinicians commonly encounter patients with acute pain. A new set of evidence-based guidelines (EBG) was developed to assist in the prehospital management of pain. Our objective was to describe the methods used to develop these evidence-based guidelines for prehospital pain management. METHODS: The EBG development process was supported by a previous systematic review conducted by the Agency for Healthcare Research and Quality (AHRQ) covering nine different population, intervention, comparison, and outcome (PICO) questions. A technical expert panel (TEP) was formed and added an additional pediatric-specific PICO question. Identified evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework and tabulated into Summary of Findings tables. The TEP then utilized a rigorous systematic method, including the PanelVoice function, for recommendation development which was applied to generate Evidence to Decision Tables (EtD). This process involved review of the Summary of Findings tables, asynchronous member judging, and facilitated panel discussion to generate final consensus-based recommendations. RESULTS: The work product described above was completed by the TEP panel from September 2020 to April 2021. For these recommendations, the overall certainty of evidence was very low or low, data for decisions on cost effectiveness and equity were lacking, and feasibility was rated well across all categories. Based on the evidence, one strong and seven conditional recommendations were made, with two PICO questions lacking sufficient evidence to generate a recommendation. CONCLUSION: We describe a protocol that leveraged established EBG development techniques, the GRADE framework in conjunction with a previous AHRQ systematic review to develop treatment recommendations for prehospital pain management. This process allowed for mitigation of many confounders due to the use of virtual and electronic communication. Our approach may inform future guideline development and increase transparency in the prehospital recommendations development processes.

State Requirements for Medical Directors in the United States.

BACKGROUND: The requirements for emergency medical services (EMS) medical directors are commonly defined by state rules and regulations without national standardization. The extent of variability in the requirements to be an EMS medical director in the US is unclear. The objective of this study is to describe the state requirements to function as an EMS medical director in the US. METHODS: This was an evaluation of the rules and statutes governing the current requirements to function as an agency-level EMS medical director and defined tasks in the US. Regulations and governmental statutes were reviewed from 50 states and the District of Columbia using publicly available governmental websites focusing on the specific qualifications required to work as an EMS medical director and perform the associated tasks. Data were tabulated, and descriptive statistics were calculated. RESULTS: Data were available and extracted for all 50 states and the District of Columbia. Being a licensed physician is the minimum requirement in 50 states (50/51, 98%). One state, Montana, allows for medical direction by a licensed physician or physician assistant. Board certification in emergency medicine is required by 8% (4/51). No state requires EMS subspecialty certification. The majority of states require that EMS medical directors participate in EMS oversight (76%), EMS clinician training (71%), protocol development (67%), and quality improvement and assurance (65%). CONCLUSIONS: Requirements for EMS medical direction across the US are not standardized. Many states require a medical license, but emergency medicine board certification is not a common requirement. Future work will need to focus on required competencies for EMS medical direction to set clear standards and educational requirements in the US.

Evidence-Based Guidelines for Prehospital Pain Management: Recommendations.

This project sought to develop evidence-based guidelines for the administration of analgesics for moderate to severe pain by Emergency Medical Services (EMS) clinicians based on a separate, previously published, systematic review of the comparative effectiveness of analgesics in the prehospital setting prepared by the University of Connecticut Evidence-Based Practice Center for the Agency for Healthcare Research and Quality (AHRQ). A technical expert panel (TEP) was assembled consisting of subject matter experts in prehospital and emergency care, and the development of evidence-based guidelines and patient care guidelines. A series of nine "patient/population-intervention-comparison-outcome" (PICO) questions were developed based on the Key Questions identified in the AHRQ systematic review, and an additional PICO question was developed to specifically address analgesia in pediatric patients. The panel made a strong recommendation for the use of intranasal fentanyl over intravenous (IV) opioids for pediatric patients without intravenous access given the supporting evidence, its effectiveness, ease of administration, and acceptance by patients and providers. The panel made a conditional recommendation for the use of IV non-steroidal anti-inflammatory drugs (NSAIDs) over IV acetaminophen (APAP). The panel made conditional recommendations for the use of either IV ketamine or IV opioids; for either IV NSAIDs or IV opioids; for either IV fentanyl or IV morphine; and for either IV ketamine or IV NSAIDs. A conditional recommendation was made for IV APAP over IV opioids. The panel made a conditional recommendation against the use of weight-based IV ketamine in combination with weight-based IV opioids versus weight-based IV opioids alone. The panel considered the use of oral analgesics and a conditional recommendation was made for either oral APAP or oral NSAIDs when the oral route of administration was preferred. Given the lack of a supporting evidence base, the panel was unable to make recommendations for the use of nitrous oxide versus IV opioids, or for IV ketamine in combination with IV opioids versus IV ketamine alone. Taken together, the recommendations emphasize that EMS medical directors and EMS clinicians have a variety of effective options for the management of moderate to severe pain in addition to opioids when designing patient care guidelines and caring for patients suffering from acute pain.

EMS Program Graduates Who Did Not Retest after Initial Attempt on the National Certification Exam.

Introduction: Becoming an EMS professional in most of the United States requires successful completion of the National Certification process. While multiple attempts are allowed, some candidates who are unsuccessful on their first cognitive examination attempt do not return despite personal investment. Objective: We describe the demographic and testing characteristics of EMT and paramedic candidates that do not return for a second examination attempt after an initial unsuccessful attempt on the National EMS Certification Cognitive Examination. Methods: This was a cross-sectional evaluation of nonmilitary EMT and paramedic graduates, between ages 18 and 85 years, who completed their education program in 2016, attempted the National Certification Examination, and were unsuccessful. Multivariable logistic regression models were used to estimate the odds of retesting for EMT and paramedic graduates for age, sex, initial test length, and elapsed time from course completion to initial examination. Results: Of all EMT graduates eligible to retest (n = 22,088), 33% (n = 7,208) did not retest. Adjusted odds of retesting for EMT graduates decreased with female sex, time from course completion to initial examination, and those with minimal exam length. Adjusted odds of retesting for EMT graduates increased in 20-21 and 22-24 year olds compared to 18-19 year olds. Similarly, of all paramedic graduates eligible to retest (n = 2,755), 14% (n = 390) did not. Adjusted odds of retesting at the paramedic level decreased with time from course completion to initial examination and minimum exam length. Age and sex were not significant contributors to odds of retesting for paramedics. Conclusion: Many EMTs and paramedics who were unsuccessful on the National Certification Exam did not retest. Factors identified that impact the choice varied between EMTs and paramedics but included age, sex, length of initial examination, and time from course completion to that initial examination. These characteristics may present actionable items for EMS educational programs and stakeholders to support EMT and paramedic graduates at risk of not entering the workforce.

COVID-19 Vaccinations in EMS Professionals: Prevalence and Predictors.

Background: Immunizations for emergency medical services (EMS) professionals during pandemics are an important tool to increase the safety of the workforce as well as their patients. The purpose of this study was to better understand EMS professionals' decisions to receive or decline a COVID-19 vaccine.Methods: We conducted a cross-sectional analysis of nationally certified EMS professionals (18-85 years) in April 2021. Participants received an electronic survey asking whether they received a vaccine, why or why not, and their associated beliefs using three validated scales: perceived risk of COVID-19, medical mistrust, and confidence in the COVID-19 vaccine. Data were merged with National Registry dataset demographics. Analyses included descriptive analysis and multivariable logistic regression (OR, 95% CI). Multivariate imputation by chained equations was used for missingness.Results: A total of 2,584 respondents satisfied inclusion criteria (response rate = 14%). Overall, 70% of EMS professionals were vaccinated. Common reasons for vaccination among vaccinated respondents were to protect oneself (76%) and others (73%). Common reasons for non-vaccination among non-vaccinated respondents included concerns about vaccine safety (53%) and beliefs that vaccination was not necessary (39%). Most who had not received the vaccine did not plan to get it in the future (84%). Hesitation was most frequently related to wanting to see how the vaccine was working for others (55%). Odds of COVID-19 vaccination were associated with demographics including age (referent <28 years; 39-50 years: 1.56, 1.17-2.08; >51 years: 2.22, 1.64-3.01), male sex (1.26, 1.01-1.58), residing in an urban/suburban area (referent rural; 1.36, 1.08-1.70), advanced education (referent GED/high school and below; bachelor's and above: 1.72, 1.19-2.47), and working at a hospital (referent fire-based agency; 1.53, 1.04-2.24). Additionally, vaccination odds were significantly higher with greater perceived risk of COVID-19 (2.05, 1.68-2.50), and higher vaccine confidence (2.84, 2.40-3.36). Odds of vaccination were significantly lower with higher medical mistrust (0.54, 0.46-0.63).Conclusion: Despite vaccine availability, not all EMS professionals had been vaccinated. The decision to receive a COVID-19 vaccine was associated with demographics, beliefs regarding COVID-19 and the vaccine, and medical mistrust. Efforts to increase COVID-19 vaccination rates should emphasize the safety and efficacy of vaccines.

Paramedic and EMT Program Performance on Certification Examinations Varies by Program Size and Geographic Location.

Introduction: The quality of an Emergency Medical Technician (EMT) or paramedic training program is likely one factor that contributes to a candidate's success on the National Registry Cognitive Examination. However, program pass rates and their associated geographic location have not previously been evaluated. Our objective was to evaluate the performance of EMT and paramedic programs in the United States, pass rates on the National Registry Cognitive Examinations, and relationship to geography.Methods: We conducted a cross-sectional evaluation of EMT and paramedic programs' first and cumulative third attempt pass rates on the National Registry Cognitive Examination in 2015. Included were civilian EMT and paramedic programs with >5 graduates testing for certification. Descriptive statistics were calculated for program pass rates, total graduates testing, and pass rates by National Association of State EMS Officials (NASEMSO) regions.Results: We included 1,939 EMT programs (6-1,892 graduates testing/program) and 602 paramedic programs (6-689 graduates testing/program). We excluded 262 (11.9%) EMT and 51 (7.8%) paramedic programs with ≤5 graduates testing annually due to unstable estimates of program pass rates. EMT programs in the highest quartile for total number of graduates testing outperformed the lowest quartile in both first attempt (65.7% vs. 61.9%, p < 0.001) and cumulative third attempt pass rates (79.1% vs 72.7%, p < 0.001). This difference was also seen for paramedic programs on first attempt (77.3% vs. 62.5%, p < 0.001) and cumulative third attempt (91.9% vs. 76.9%, p < 0.001). EMT program pass rates for first and cumulative third attempts also varied by NASEMSO region (first: 62-68%; third: 74-78%) with the Great Lakes and West regions outperforming the other regions. Paramedic program pass rates differed by NASEMSO regions as well (first: 65-83%; third: 81-95%) with highest pass rates in the West region.Conclusions Program performance for both EMT and paramedic programs varies by total number of graduates testing and geographic location. Graduates from larger EMT and paramedic programs have higher first and cumulative third attempt pass rates compared to graduates from smaller programs. Additionally, there is variability in program pass rates across NASEMSO regions for both certification levels. Further evaluation is necessary to better understand the variability in program performance in the United States.

Emergency Medical Services Personnel Awareness and Training about Personal Protective Equipment during the COVID-19 Pandemic.

Background: With the emergence of the 2019 novel coronavirus disease (COVID-19), appropriate training for emergency medical services (EMS) personnel on personal protective equipment (PPE) is essential. We aimed: 1) to examine the change in proportions of EMS personnel reporting awareness of and training in PPE during the COVID-19 pandemic; and 2) to determine factors associated with reporting these outcomes.We conducted a cross-sectional analysis of data collected from October 1, 2019 to June 30, 2020 from currently working, nationally certified EMS personnel (n = 15,339), assessing N95 respirator fit testing; training in air purified respirators (APR) or powered APR (PAPR) use; and training on PPE use for chemical, biological, and nuclear (CBN) threats. We used an interrupted time series analysis to determine changes in proportions of EMS personnel reporting training per week, using the date of Centers for Disease Control and Prevention's (CDC) initial EMS guidance (February 6, 2020) as the interruption. We fit multivariable logistic regression models to understand factors associated with each outcome.Results: We found high awareness of N95 respirators (99%) and APR/PAPR (91%), but only 61% reported N95 fit testing and 64% reported training on PPE for CBN threats in the prior 12 months. There was a significant, positive slope change after CDC guidance for N95 respirator fit testing, and significant post-interruption mean increases for fit testing (0.9%, 95% CI 0.6-1.1%), APR/PAPR training (0.3%, 95% CI 0.2-0.5%), and PPE for CBN threats training (0.6%, 95% CI 0.3-0.9%). Factors consistently associated with lower odds of awareness/training included part-time employment, providing 9-1-1 response service, working at a non-fire-based EMS agency, and working in a rural setting.Conclusions: CDC guidance on COVID-19 for EMS may have increased N95 fit testing and training, but there remain substantial gaps in training on PPE use among EMS personnel. As the pandemic continues in our communities, EMS agencies should be supported in efforts to adequately prepare their staff.

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.

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.

EMS Responses for Pediatric Behavioral Health Emergencies in the United States: A 4-Year Descriptive Evaluation.

BACKGROUND: The occurrence of behavioral health emergencies (BHEs) in children is increasing in the United States, with patient presentations to Emergency Medical Services (EMS) behaving similarly. However, detailed evaluations of EMS encounters for pediatric BHEs at the national level have not been reported. METHODS: This was a secondary analysis of a national convenience sample of EMS electronic patient care records (ePCRs) collected from January 1, 2018 through December 31, 2021. Inclusion criteria were all EMS activations documented as 9-1-1 responses involving patients < 18 years of age with a primary or secondary provider impression of a BHE. Patient demographics, incident characteristics, and clinical variables including administration of sedation medications, use of physical restraint, and transport status were examined overall and by calendar year. RESULTS: A total of 1,079,406 pediatric EMS encounters were present in the dataset, of which 102,014 (9.5%) had behavioral health provider impressions. Just over one-half of BHEs occurred in females (56.2%), and 68.1% occurred in patients aged 14-17 years. Telecommunicators managing the 9-1-1 calls for these events reported non-BHE patient complaints in 34.7%. Patients were transported by EMS 68.9% of the time, while treatment and/or transport by EMS was refused in 12.5%. Prehospital clinicians administered sedation medications in 1.9% of encounters and applied physical restraints in 1.7%. Naloxone was administered for overdose rescue in 1.5% of encounters. CONCLUSION: Approximately one in ten pediatric EMS encounters occurring in the United States involve a BHE, and the majority of pediatric BHEs attended by EMS result in transport of the child. Use of sedation medications and physical restraints by prehospital clinicians in these events is rare. National EMS data from a variety of sources should continue to be examined to monitor trends in EMS encounters for BHEs in children.
