Abstract WP93: Providing Stroke Reports to Emergency Medical Services (EMS) Agencies Improves Data Quality in Michigan's Statewide EMS Data Repository

Intro: The Michigan Stroke Program (MiSP) monitors statewide EMS stroke care performance and data quality. Starting in 2018, quarterly performance and outcome benchmark data were shared with EMS agency partners to support prehospital quality improvement (QI) for stroke patients. Objective: To improve EMS data quality and prehospital stroke care performance. Methods: This is a retrospective before and after study of the impact of tailored QI interventions to improve EMS compliance with three prehospital stroke quality metrics selected by MiSP EMS partners: (prehospital stroke scale documentation, last known well documentation, and prehospital notification). Five MiSP EMS partners participated in the intervention which consisted of provision of quarterly performance reports generated from linked data from Michigan’s EMS Information System and the Michigan Stroke Registry. The MiSP team reviewed agency performance with EMS leadership to select the target measures for intervention and then assisted in development of a QI plan to improve agency performance. Measure compliance was compared from three months prior to and six months after data quality solutions were implemented. Results: Through data sharing and communication with EMS agencies and EMS software data vendors, common themes were identified related to poor data quality beginning in January 2020. A sample of agencies and resolutions to address these issues are displayed in the Table. Compliance with the targeted metric improved significantly at each agency at three and six months following intervention. Conclusions: Analysis of EMS data and sharing performance data directly with EMS agency partners identified correctable data quality issues negatively impacting EMS quality measures. Correcting these issues led to dramatic and sustained improvement in EMS quality metric compliance. This approach may serve as a model for improving the accuracy of EMS performance data in state-level EMS registries.

The Female Emergency Medical Services Experience: A Mixed Methods Study

Background Emergency Medical Services (EMS) is a challenging profession. Little is known if there are gender differences in the experiences among EMS clinicians. Therefore, our aim was to understand and characterize the occupational experiences of female EMS clinicians. Methods A mixed methodological study was conducted among currently licensed female EMS clinicians via focus group and self-report survey data. Three focus groups (n = 5, 4, 13, respectively) were conducted with participants purposively recruited from primarily Northeastern EMS agencies. Through ongoing collaborations, a recruitment advertisement was provided to EMS leadership at respective agencies for distribution among their female staff. Sessions were recorded and transcribed for thematic analysis. A six-phase inductive analytical approach was utilized to evaluate focus group data. Qualitative findings were utilized to inform a cross-sectional, self-report survey consisting of occupational specific experiences, such as harassment and pregnancy, and validated measures of mental wellbeing. Descriptive statistics were used to describe the study sample and female EMS clinician occupational and personal experiences. Results A total of 22 female EMS clinicians participated across the three focus group sessions. Four major themes were identified: 1) the female EMS experience; 2) impact on personal wellbeing; 3) impact on occupational wellbeing; and 4) coping mechanisms. Each theme had multiple subthemes. There were 161 participants that attempted the 72-item survey, 13 partial and 148 competed surveys. Median age was 32 years (IQR: 25-42), and the majority were EMT-Bs (55.1%). Approximately 70.0% met the criteria for probable anxiety, 53.9% probable depression and 40.9% elevated symptoms of burnout. Almost 73.0% reported workplace harassment, with most experiences being perpetrated by patients and coworkers. Over 61.0% reported reconsideration of their career in EMS. Overall, survey data indicated interactions with peers and leadership, and social support were positive. Conclusions Findings highlight the need to improve the occupational experiences of female EMS clinicians to preserve and encourage the continuation of their participation in this workforce. Specifically tailored interventions aimed at protecting and improving their overall wellbeing are critical, particularly considering the increased occupational burden resulting from the pandemic. Future research should aim to understand specific predictors of adverse mental health outcomes among this population.

EMS Potentials in MENA region

Background Emergency Medical Services (EMS) have been always considered as a vital service provided by of many Red Cross and Red Crescent (RCRC) national societies worldwide and in Middle East and North Africa (MENA) region in particular during emergency and non-emergency contexts. The role to supporting the national wide health system in prehospital stage has got special attention during COVID 19 due to overwhelming health care facilities. The national societies have played a key role in mitigating the impact of the COVID 19 on the healthcare facilities by activating and growing their EMS capacities and expanding their scope of services in the prehospital stage. To define capacities and areas for improvement in RCRC national societies, we've developed a tool to survey different aspects of EMS. Methodology A questionnaire was designed by the IFRC MENA health team based on Prehospital emergency management system PEMS conceptual framework for assessment. 67 questions were grouped into 5 domains: governance and dispatch, Human Resources (H.R.) & Logistics, EMS Education, EMS operation and quality , and EMS disaster preparedness. Two open-ended questions were added to define areas of improvement and what national societies can offer to enhance capacities for other national societies in the region… The questionnaire was piloted with EMS leaders at Lebanese Red Cross. Between the period of April 2022 and August 2022, the online questionnaire was sent to four national society EMS managements, Lebanese Red Cross LRC , Palestine Red Crescent Society PRCS , Saudi Red Crescent Authority SRCA and Syria Arab Red Crescent SARC. The answers were collected using SurveyMonkey platform and validation workshops were held with all four EMS managements. For the qualitative questions of the perceived weaknesses and strengths, interviews with EMS managements were recorded and transcript. Analysis tools of SurveyMonkey was utilized for quantitative data analysis, and qualitative data was explored manually using thematic analysis methodology. Results The input from the four national societies revealed variation in governance, structure, and scope of services of EMS among them. We can highlight the main outcomes under each domain EMS Governance and Dispatch The four NSs are considering scoop and run operational model. The percentage of acute to cold cases in day to day practice is varying with predominance of cold cases among all. SRCA, PRCS in West Bank, and LRCS central dispatch center are using fully automated dispatch system, while LRC is using semi-automated in the regional dispatch centers, and SARC and PRCS branches in Gaza and Jerusalem are using manual (paper based) dispatch system. EMS H.R. & Logistics LRC, PRCS and SARC are mainly relying on volunteers to run EMS daily operations while SRCA depends on 6000 full time employees to operate 24/7 EMS services. SRCA EMS fleet is considered the largest among the four NSs with around 1,400 vehicles, LRC came next with 390 vehicles, then PRCS with 180, and lastly SARC with 112. EMS Education Both LRC and SRCA are running international accredited emergency courses including Basic Life Support (BLS), Advanced Life Support, Prehospital Trauma Life Support (PTLS), Advanced Trauma Life Support, and other relevant courses. On the other hand, PRCS and SARC are considering academic and locally customized training courses to train their EMS staff and volunteers. EMS Operation and Quality The service coverage of the four EMS in urban areas ranges between 80 – 100% while coverage decreases in rural areas to reach under 50% in some regions. Quality assurance and regular monitoring are areas that need to be standardized and systematized in most cases. EMS Disaster Preparedness Specialized training program for Mass Causality Incidences (MCI) is conducted in LRC, PRCS and SRCA. LRC, SARC, and SRCA possess a standardized approach for major incidence management as part of their disaster management

Diversity, Equity, and Inclusion in the United States Emergency Medical Services Workforce: A Scoping Review

Objective Emergency medical services (EMS) workforce demographics in the United States do not reflect the diversity of the population served. Despite some efforts by professional organizations to create a more representative workforce, little has changed in the last decade. This scoping review aims to summarize existing literature on the demographic composition, recruitment, retention, and workplace experience of underrepresented groups within EMS. Methods Peer-reviewed studies were obtained from a search of PubMed, CINAHL, Web of Science, ProQuest Thesis and Dissertations, and non-peer-reviewed (“gray”) literature from 1960 to present. s and included full-text articles were screened by two independent reviewers trained on inclusion/exclusion criteria. Studies were included if they pertained to the demographics, training, hiring, retention, promotion, compensation, or workplace experience of underrepresented groups in United States EMS by race, ethnicity, sexual orientation, or gender. Studies of non-EMS fire department activities were excluded. Disputes were resolved by two authors. A single reviewer screened the gray literature. Data extraction was performed using a standardized electronic form. Results were summarized qualitatively. Results We identified 87 relevant full-text articles from the peer-reviewed literature and 250 items of gray literature. Primary themes emerging from peer-reviewed literature included workplace experience (n = 48), demographics (n = 12), workforce entry and exit (n = 8), education and testing (n = 7), compensation and benefits (n = 5), and leadership, mentorship, and promotion (n = 4). Most articles focused on sex/gender comparisons (65/87, 75%), followed by race/ethnicity comparisons (42/87, 48%). Few articles examined sexual orientation (3/87, 3%). One study focused on telecommunicators and three included EMS physicians. Most studies (n = 60, 69%) were published in the last decade. In the gray literature, media articles (216/250, 86%) demonstrated significant industry discourse surrounding these primary themes. Conclusions Existing EMS workforce research demonstrates continued underrepresentation of women and nonwhite personnel. Additionally, these studies raise concerns for pervasive negative workplace experiences including sexual harassment and factors that negatively affect recruitment and retention, including bias in candidate testing, a gender pay gap, and unequal promotion opportunities. Additional research is needed to elucidate recruitment and retention program efficacy, the demographic composition of EMS leadership, and the prevalence of racial harassment and discrimination in this workforce.

Emergency Medical Services Leadership Perspectives on Implementation of Evidence-Based Guidelines: A Qualitative Study

ABSTRACT Introduction: Prehospital evidence-based guidelines (EBGs) are developed to optimize clinical outcomes for emergency medical services (EMS) patients. However, widespread implementation of EBGs is often inconsistent. Therefore, this study aimed to assess the baseline knowledge and practices of EMS leaders related to EBG implementation. Methods: This was a qualitative study using focus groups to assess prehospital implementation awareness and knowledge. Participants were EMS EBG authors, EMS medical directors, and EMS professional organization leaders. Focus groups were held via video conference, audio recorded, and transcribed. Thematic coding used domains and constructs of the Consolidated Framework for Implementation Research (CFIR). Results: Six focus groups were conducted with a total of 18 participants. A total of 1,044 codes were analyzed. “Process” was the CFIR domain with the most codes (n = 350, 33.5%), followed by the “inner setting” (the EMS agency; n = 250, 23.9%), “characteristics of the intervention” (n = 203, 19.4%), “outer setting” (the health care system and community the EMS agency serves, and the broader national EMS professional context; n = 141, 13.5%), and “characteristics of individuals” (n = 100, 9.6%). The ten most frequent constructs across all domains were: reflecting and evaluating, executing, cosmopolitanism, planning, external policy and incentives, design quality and packaging, learning climate, culture, complexity, and other personal attributes. Conclusion: EMS leadership and stakeholder views on EBG implementation identified dominant themes related to the process of implementation and the culture and learning/implementation climate of EMS agencies. Opinions were mixed on the utility of the CFIR as a potential guide for EMS implementation. Further work is required to gain the frontline EMS clinician perspective on implementation and tie key themes to quantitative prehospital implementation outcomes.

Guest Editorial: AAENP Releases Position Statement: The Role of Nurse Practitioners in Emergency Medical Services.

Recently, there has been a national discussion about nurse practitioners (NPs) working within emergency medical services (EMS). The National Association of EMS Physicians, the Society for Emergency Medicine Physician Assistants (SEMPA), and most recently, the American Academy of Emergency Nurse Practitioners (AAENP) have all issued position statements on this issue (AAENP, 2022; SEMPA, 2021; Wright et al., 2021). The joint mission should be centered around high-quality patient care, a multidisciplinary team, and elevating the level of NP practice available in the prehospital and interfacility settings. NPs working in prehospital roles can add value to rural, suburban, and urban environments. In rural America, providing adequate EMS response creates challenges for ambulance providers (National Rural Health Association, 2018). Urban EMS programs are already utilizing NPs as a potential solution to augment care delivery within the EMS system in various roles (Sanko et al., 2020). However, NPs face regulatory challenges, limiting or prohibiting more active involvement in the EMS system. According to the American Association of Nurse Practitioners (AANP), NPs in full practice authority states are more likely to practice in rural and underserved areas (AANP, 2022). To enable NPs to contribute more to prehospital care, national health care practice models and state regulators must consider rule changes that strengthen the utilization of NPs in EMS systems. NPs with appropriate training are in an ideal space to support rural EMS systems. In addition, there are barriers to NPs working in EMS leadership roles. One of the most significant barriers is the National Registry of Emergency Medical Technicians (NREMT, 2019) requirement that all paramedics and advanced emergency medical technicians have a physician medical director. This rule becomes problematic in some of the most rural areas of the country that struggle to find medical direction. Although medical directors trained in EMS fellowships may be ideal, the physician-only language written in NREMT's guidelines marginalizes rural health care and prevents qualified NPs from participating in certain levels of medical direction. AAENP (2022) believes that “NPs are uniquely positioned to provide and direct care of the patient within a multidisciplinary EMS system. The AAENP supports utilization of NPs in EMS to the full extent of their licensure, education, and scope of practice based on state and agency regulations.” —Wesley D.

Emergency Medical Services Demand: An Analysis of County-Level Social Determinants.

Variations in the demand for Emergency Medical Services (EMS) exist when observed at a local level. This unspecified heterogeneity leads to an investigation of social factors contributing to EMS demand. Data for this study were collected from publicly available EMS reports from Florida and Oklahoma for 2009 - 2015. Health and social data were gathered from County health rankings and roadmap reports. Data were combined into a single dataset, and pooled ordinary-least-squares models with time-fixed effects were utilized for tests of inference. EMS call volume was log-transformed to derive a semi-elasticity function. A total of 874 county-year observations were analyzed. Increases in poor/fair health (95% CI: 0.6% - 3.9%), binge drinking (95% CI: 1.6% - 3.5%), teen birth rate (95% CI: 1.1% - 5.2%), unemployment rate (95% CI: 0.5% - 3.9%), and violent crime rate (95% CI: 1.0% - 3.0%) were associated with an increase in the EMS demand rate. The data supports the notion that some community measures have an effect on EMS demand as counties with higher levels of poor health, binge drinking, teen births, unemployment, and violent crime saw higher EMS demand. These factors may have been treated as spurious, or overlooked by policy makers and EMS leadership.

Using Red Lights and Sirens for Emergency Ambulance Response: How Often Are Potentially Life-Saving Interventions Performed?

Background Emergency Medical Services (EMS) often respond to 911 calls using red lights and sirens (RLS). RLS is associated with increased collisions and increased injuries to EMS personnel. While some patients might benefit from time savings, there is little evidence to guide targeted RLS response strategies. Objective To describe the frequency and nature of 911 calls that result in potentially life-saving interventions (PLSI) during the call. Methods Using data from ESO (Austin, Texas, USA), a national provider of EMS electronic health records, we analyzed all 911 calls in 2018. We abstracted the use of RLS, call nature, and interventions performed. A liberal definition of PLSI was developed a priori through a consensus process and included both interventions, medications, and critical hospital notifications. We calculated the proportion of calls with RLS response and with PLSI performed, both overall and stratified by call nature. Results There were 5,977,612 calls from 1,187 agencies included in the analysis. The majority (85.8%) of calls utilized RLS, yet few (6.9%) resulted in PLSI. When stratified by call nature, cardiac arrest calls had the highest frequency PLSI (45.0%); followed by diabetic problems (37.0%). Glucose was the most frequently given PLSI, n = 69,036. When including multiple administrations to the same patient, epinephrine was given most commonly PLSI, n = 157,282 administrations). Conclusion In this large national dataset, RLS responses were very common (86%) yet potentially life-saving interventions were infrequent (6.9%). These data suggest a methodology to help EMS leaders craft targeted RLS response strategies.

Pediatric Readiness in Emergency Medical Services Systems.

Ill and injured children have unique needs that can be magnified when the child's ailment is serious or life-threatening. This is especially true in the out-of-hospital environment. Providing high-quality out-of-hospital care to children requires an emergency medical services (EMS) system infrastructure designed to support the care of pediatric patients. As in the emergency department setting, it is important that all EMS agencies have the appropriate resources, including physician oversight, trained and competent staff, education, policies, medications, equipment, and supplies, to provide effective emergency care for children. Resource availability across EMS agencies is variable, making it essential that EMS medical directors, administrators, and personnel collaborate with outpatient and hospital-based pediatric experts, especially those in emergency departments, to optimize prehospital emergency care for children. The principles in the policy statement "Pediatric Readiness in Emergency Medical Services Systems" and this accompanying technical report establish a foundation on which to build optimal pediatric care within EMS systems and serve as a resource for clinical and administrative EMS leaders.

The Use of Emergency Lights and Sirens by Ambulances and Their Effect on Patient Outcomes and Public Safety: A Comprehensive Review of the Literature - ADDENDUM.

The benefits of emergency lights and sirens (L&S) use as warning devices by ambulances continue to be a debated topic in Emergency Medical Services (EMS). While the most widely studied aspect of L&S use has been related to their effect on ambulance response and transport times, the literature suggests minimal time savings with more questionable impact on actual patient outcomes. As L&S use has been shown to increase the risk for vehicle crashes, the secondary concern of ambulance design and safety also becomes an important aspect on potential design recommendations that could mitigate the effects of a crash on patients, EMS providers, and the general public. The least studied aspect of L&S use (and probably the most important) is their effect on patient outcomes and quality of medical care during transport. The current evidence suggests no significant improvement on patient outcomes and potential worsening to certain aspects of patient care during transport. The purpose of this review was to examine the current literature regarding ambulance L&S use and the risks they pose to EMS providers, patients, and the general public. In doing so, it will provide sound background for EMS leaders to better develop policies governing the use of L&S by ambulances and promote better research in the patient outcomes effect associated with their use. This review offers some strategies in mitigating the risks associated with L&S use, such as ways to reduce their overall use and modifying other related factors to emergency medical vehicle collisions (EMVCs).

Emergency Medical Services Provider Perspectives on Pediatric Calls: A Qualitative Study

Objective: Previous research indicates that 9-1-1 response to incidents involving children is particularly distressing for emergency medical services (EMS) clinicians. This qualitative study was conducted to increase understanding about the difficulties of responding to pediatric calls and to obtain information about how organizations can better support EMS providers in managing potentially difficult calls. Methods: Paramedics and emergency medical technicians from a single U.S. ambulance service were invited to participate in focus groups about responding to 9-1-1 calls involving pediatric patients. A total of 17 providers from both rural and metro service regions participated in six focus groups held in community meeting spaces. A semi-structured focus group guide was used to explore (1) elements that make pediatric calls difficult, (2) pre-arrival preparation practices, (3) experiences with coping after difficult pediatric calls, and (4) perspectives about offered and desired resources or support. Focus groups were audio recorded and transcripts were analyzed using standard coding, memoing, and content analysis methods in qualitative analysis software (NVivo). Results: Responses about elements that make pediatric calls difficult were organized into the following themes: (1) special social value of children, (2) clinical difficulties with pediatric patients, (3) added acuity to already challenging calls, (4) caregivers as secondary patient, and (5) identifying with patient or patient’s family. Pre-arrival preparation methods included mental or verbal review of hypothetical scenarios and refocusing nerves or emotions back to the technical aspect of the job. Participants described using available resources that largely took the form of social support. Suggestions for additional resources included: increased opportunities for external feedback; more frequent pediatric clinical training; institutionalization of recovery time after difficult calls; and improved storage and labeling of pediatric equipment. Conclusions: This study provides qualitative data about the difficulties of responding to pediatric calls and resources needed to support clinicians. Findings from this study can be used to guide EMS leaders in designing and implementing institutional initiatives to enhance training and support for prehospital clinicians providing care to children.

P010: A systematic review of the association between emergency medical services (EMS) time factors and survival

Introduction: EMS time factors such as total prehospital, activation, response, scene and transport intervals have been used as a measure of EMS system quality with the assumption that shorter EMS time factors save lives. The objective was to assess in adults and children accessing ground EMS (population), whether operational time factors (intervention and control) were associated with survival at hospital discharge (outcome). Methods: Medline, EMBASE, and CINAHL were searched up to January 2015 for articles reporting original data that associated EMS operational time factors and survival. Conference abstracts and non-English language articles were excluded. Two investigators independently assessed the candidate titles, abstracts, and full text with discrepant reviews resolved by consensus. Risk of bias was assessed using GRADE. Results: A total of 10,151 abstracts were screened for potential inclusion, 199 articles were reviewed in full-text, and 73 met inclusion criteria. Amongst included studies, 49 investigated response time, while 24 investigated other time factors. All articles were observational studies. Amongst the 14 (28.6%) studies where response time was the primary analysis, statistically significant associations between shorter response time and increased survival were found in 5 of 7 cardiac arrest, 1 of 5 general EMS population, and 0 of 2 trauma studies. Other time factors were reported in the primary analysis in 10 (41.7%) studies. One study reported shorter combined scene and transport intervals associated with increased survival in acute heart failure patients. Two studies in trauma patients had somewhat conflicting results with one study reporting shorter prehospital interval associated with increased survival whereas the other reported increased survival associated with longer scene and transport intervals. Study design, analysis, and methodological quality were of considerable variability, and thus, meta-analyses were not possible. Conclusion: There is a substantial body of literature describing the association between EMS time factors and survival, but evidence informing these relationships are heterogeneous and complex. Important details such as patient population, EMS system characteristics, and analytical approach must be taken into consideration to appropriately translate these findings to practice. These results will be important for EMS leaders wishing to create evidence-based time policies.
