Development and Deployment of a Pre-planned Hospital Emergency Response Team (HERT) for EMS Augmentation: Case Report and Program Review.

With the establishment and growth of the Emergency Medical Services (EMS) subspecialty, significant attention has been focused on clinical activities performed by EMS physicians in the out-of-hospital environment. An EMS fellowship includes special operations education to develop preparedness for responding to field situations requiring physician expertise. With only a thousand Board Certified EMS physicians in North America, EMS physicians may not be available 24 hours per day to respond to field emergencies. Non-EMS physicians with minimal experience in prehospital or austere care may be called upon to respond to complex prehospital emergencies requiring advanced skills. The Los Angeles County EMS Agency implemented a policy in 1992 to establish Hospital Emergency Response Teams (HERT) as a regional resource to provide time-critical, specialized prehospital services within an EMS system (1). Activation of the HERT is rare, most frequently prompted by need for field amputation to enable extrication. We describe one such incident of a field intervention by HERT and detail the staffing, training, and equipment considerations within our large regional EMS system.

The hospital costs of high emergency department pediatric readiness.

Objective: We estimate annual hospital expenditures to achieve high emergency department (ED) pediatric readiness (HPR), that is, weighted Pediatric Readiness Score (wPRS) ≥ 88 (0-100 scale) across EDs with different pediatric volumes of children, overall and after accounting for current levels of readiness. Methods: We calculated the annual hospital costs of HPR based on two components: (1) ED pediatric equipment and supplies and (2) labor costs required for a Pediatric Emergency Care Coordinator (PECC) to perform pediatric readiness tasks. Data sources to generate labor cost estimates included: 2021 national salary information from U.S. Bureau of Labor Statistics, detailed patient and readiness data from 983 EDs in 11 states, the 2021 National Pediatric Readiness Project assessment; a national PECC survey; and a regional PECC survey. Data sources for equipment and supply costs included: purchasing costs from seven healthcare organizations and equipment usage per ED pediatric volume. We excluded costs of day-to-day ED operations (ie, direct clinical care and routine ED supplies). Results: The total annual hospital costs for HPR ranged from $77,712 (95% CI 54,719-100,694) for low volume EDs to $279,134 (95% CI 196,487-362,179) for very high volume EDs; equipment costs accounted for 0.9-5.0% of expenses. The total annual cost-per-patient ranged from $3/child (95% CI 2-4/child) to $222/child (95% CI 156-288/child). After accounting for current readiness levels, the cost to reach HPR ranged from $23,775 among low volume EDs to $145,521 among high volume EDs, with costs per patient of $4/child to $48/child. Conclusions: Annual hospital costs for HPR are modest, particularly when considered per child.

Prehospital Care for Persons Experiencing Homelessness: A Cross-Sectional Survey of the Challenges, Experiences, and Perspectives of Operational EMS Agency Medical Directors.

OBJECTIVE: Persons experiencing homelessness (PEH) are among the most vulnerable populations and experience significant health disparities. Nationally, PEH utilize Emergency Medical Services (EMS) at disproportionately higher rates than their housed peers. Developing optimal strategies to care for PEH has become critically important. However, limited data exists on best practices, challenges, and experiences of providing care to PEH. The objective of this study was to describe the experiences, challenges and perspectives of operational EMS agency medical directors in Los Angeles (LA) County as they confront the homelessness crisis. METHODS: We performed a cross-sectional survey of 9-1-1 operational EMS agency medical directors in LA County, which has one of the largest populations of PEH nationally. Twenty-nine 9-1-1 operational EMS agencies operate in LA County. The link to an anonymous, web-based survey examining documentation, training, resources, operational impact, and care challenges was emailed to medical directors with three reminders during the study period (4/19/2023-9/15/2023). RESULTS: Three quarters (75.9%; 22/29) of operational EMS agencies responded to the survey, with all questions answered in 69% (20/29) of surveys. Of these, 68.2% (15/22) of agencies document housing status and 75% (15/20) agreed or strongly agreed that homelessness presents operational challenges. No operational EMS agency reported adequate EMS clinician training on homelessness. Operational EMS agencies most commonly utilized domestic violence resources (43%, 9/21), social services (38%, 8/21), and law enforcement (38%, 8/21) services to assist PEH. Referrals were limited by accessibility (86%, 18/21), time (52%, 11/21), lack of awareness (52% 11/21) and lack of mandates (52%, 11/21). All operational EMS agencies agreed or strongly agreed that mental health and substance use disorders are major issues for PEH. The most common daily challenges reported were mental health (55%, 11/20), substance use (55%, 11/20), and patient resistance (35%, 7/20). CONCLUSION: In LA County, EMS agencies experience important operational and clinical challenges in caring for PEH, with limited resources, minimal training, and high rates of substance use disorders and mental health comorbidities. Further prehospital research is essential to standardize documentation of housing status, to identify areas for intervention, increase linkage to services, and define best practices.

Advancing Emergency Medical Services' (EMS) Response Capability for Behavioral Health Emergencies: Los Angeles County's Performance Improvement Initiative.

INTRODUCTION: Behavioral health emergencies (BHEs) are a common patient encounter for emergency medical services (EMS) clinicians and other first responders, in particular law enforcement (LE) officers. It is critical for EMS clinicians to have management strategies for BHEs, yet relatively little information exists on best practices. In 2016, the Los Angeles County EMS Agency's Commission initiated a comprehensive evaluation of the 9-1-1 response for BHEs and developed a plan for improving the quality of care and safety for patients and first responders. METHODS: A Behavioral Health Initiative Committee was assembled with broad representation from EMS, LE, health agencies, and the public. Committee objectives included: 1) produce a process map of the BHE response from the time of a 9-1-1 call to patient arrival at transport destination, 2) identify and describe the different agencies that respond, 3) describe the critical decision points in the EMS and LE field responses, 4) acquire data that quantitatively and/or qualitatively describe the services available, and 5) recommend interventions for system performance improvement. RESULTS: The committee generated comprehensive process maps for the prehospital response to BHEs, articulated principles for evaluation, and described key observations of the current system including: 9-1-1 dispatch criteria are variable and often defaults to a LE response, the LE response inadvertently criminalizes BHEs, EMS field treatment protocols for BHEs (and especially agitated patients) are limited, substance use disorder treatment lacks integration, destination options differ by transporting agency, and receiving facilities' capabilities to address BHEs are variable. Recommendations for performance improvement interventions and initial implementation steps included: standardize dispatch protocols, shift away from a LE primary response, augment EMS treatment protocols for BHEs and the management of agitation, develop alternate destination for EMS transport. CONCLUSION: This paper describes a comprehensive performance improvement initiative in LAC-EMSA's 9-1-1 response to BHEs. The initiative included a thorough current state analysis, followed by future state mapping and the implementation of interventions to reduce LE as the primary responder when an EMS response is often warranted, and to improve EMS protocols and access to resources for BHEs.

Association between a Post-Resuscitation Care Bundle and the Odds of Field Rearrest after Successful Resuscitation from Out-of-Hospital Cardiac Arrest: A Pre/Post Study.

OBJECTIVES: Rearrest after successful resuscitation from out-of-hospital cardiac arrest (OHCA) is common and is associated with worse patient outcomes. However, little is known about the effect of interventions designed to prevent rearrest. We assessed the association between a prehospital care protocol for immediate management after return of spontaneous circulation (ROSC) and rates of field rearrest and survival to discharge in patients with prehospital ROSC. METHODS: This was a retrospective study of adult patients with OHCA and field ROSC within a large EMS system before (April 2017-August 2018) and after (April 2019-February 2020) implementation of a structured prehospital post-ROSC care protocol. The protocol was introduced in September 2018 and provided on-scene stabilization direction including guidance on ventilation and blood pressure support. Field data and hospital outcomes were used to compare the frequency of field rearrest, hospital survival, and survival with good neurologic outcome before and after protocol implementation. Logistic regression was used to assess the association between the post-implementation period and these outcomes, and odds ratios were reported. The association between individual interventions on these outcomes was also explored. RESULTS: There were 2,706 patients with ROSC after OHCA in the pre-implementation period and 1,780 patients in the post-implementation period. The rate of prehospital rearrest was 43% pre-implementation vs 45% post-implementation (RD 2%, 95% CI -1, 4%). In the adjusted analysis, introduction of the protocol was not associated with decreased odds of rearrest (OR 0.87, 95% CI 0.73, 1.04), survival to hospital discharge (OR 1.01, 95% CI 0.81, 1.24), or survival with good neurologic outcome (OR 0.81, 95% CI 0.61, 1.06). Post-implementation, post-ROSC administration of saline and push-dose epinephrine increased from 11% to 25% (RD 14%, 95% CI 11, 17%) and from 3% to 12% (RD 9% 95% CI 7, 11%), respectively. In an exploratory analysis, push-dose epinephrine was associated with a decreased odds of rearrest (OR 0.68, 95% CI 0.50, 0.94). CONCLUSIONS: Introduction of a post-ROSC care protocol for patients with prehospital ROSC after OHCA was not associated with reduced odds of field rearrest. When elements of the care bundle were considered individually, push-dose epinephrine was associated with decreased odds of rearrest.

Short-Term Outcomes and Patient Perceptions after Paramedic Non-Transport during the COVID-19 Pandemic.

BACKGROUND: EMS frequently encounter patients who decline transport, yet there are little data to inform the safety of patient and/or paramedic-initiated assess, treat, and refer (ATR) protocols. We determined patient decision-making and short-term outcomes after non-transport by EMS during the COVID-19 pandemic. METHODS: This was a prospective, observational study of a random sample of patients evaluated and not transported by EMS from August 2020 to March 2021. From the EMS database, we randomly selected a daily sample of adult patients with disposition of ATR. We excluded patients dispositioned against medical advice (AMA) and those in police custody. Investigators contacted patients by phone to administer a standardized survey regarding decision-making, symptom progression, follow-up care, and satisfaction with non-transport decision. We also determined the proportion of patients who re-contacted 9-1-1 within 72 h, and unexpected deaths within 72 h using coroner data. Descriptive statistics were calculated. RESULTS: Of 4613 non-transported patients, 3330 (72%) patients for whom the disposition was ATR were included. Patients were 46% male with a median age of 49 (inter-quartile range (IQR) 31-67). Median vital signs measurements fell within the normal range. Investigators successfully contacted 584/3330 patients (18%). The most common reason for failure was lack of accurate phone number. The most common reasons patients reported for not going to the ED on initial encounter were: felt reassured after the paramedic assessment (151/584, 26%), medical complaint resolved (113/584, 19%), paramedic suggested transport was not required (73/584, 13%), concern for COVID-19 exposure (57/584, 10%), and initial concern was not medical (46/584, 8%). Ninety-five percent (552/584) were satisfied with the non-transport decision and 49% (284/584) had sought follow-up care. The majority (501/584, 86%) reported equal, improved, or resolved symptoms, while 80 patients (13%) reported worse symptoms, of whom (64/80, 80%) remained satisfied with the non-transport decision. Overall, there were 154 of 3330 (4.6%) 9-1-1 recontacts within 72 h. Based on coroner data, three unexpected deaths (0.09%) occurred within 72 h of the initial EMS calls. CONCLUSION: Paramedic disposition by ATR protocols resulted in a low rate of 9-1-1 recontact. Unexpected deaths were extremely rare. Patient satisfaction with the non-transport decision was high.

Association of the COVID-19 Pandemic on Treatment Times for ST-Elevation Myocardial Infarction: Observations from the Los Angeles County Regional System.

Previous studies have documented longer treatment times and worse outcomes for patients with ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) during the COVID-19 pandemic. The objective of the present study was to evaluate the impact of the COVID-19 pandemic on treatment times and outcomes for patients with STEMI who underwent primary PCI within a regional system of care. This was a retrospective study using data from the Los Angeles County Emergency Medical Services Agency. Data on the emergency medical service activations were abstracted for patients with STEMI from March 19, 2020 to January 31, 2021, during the COVID-19 pandemic and for the same interval the previous year. All adult patients (≥18 years) with STEMI who underwent emergent coronary angiography were included. The primary end point was the first medical contact (FMC) to device time. The secondary end points included treatment time intervals, vascular complications, need for emergent coronary artery bypass surgery, length of hospital stay, and in-hospital mortality. During the study period, 3,017 patients underwent coronary angiography for STEMI, 1,893 patients pre-COVID-19 and 1,124 patients during COVID-19 (40% lower). A total of 2,334 patients (77%) underwent PCI. During the COVID-19 period, rates of PCI were significantly lower compared with the control period (75.1% vs 78.7%, p = 0.02). FMC to device time was shorter during the COVID-19 period compared with the control period (median 77.0 vs 81.0 minutes, p = 0.004). For patients with STEMI complicated by out-of-hospital cardiac arrest, FMC to device time was similar during the COVID-19 period compared with the control period (median 95.0 [33.0] vs 100.0 [40.0] minutes, p = 0.34). Vascular complications, the need for emergent bypass surgery, length of hospital stay, and in-hospital mortality were similar between the periods. In conclusion, in this large regional system of care, we found a relatively small but significant decrease in treatment times, yet overall, similar clinical outcomes for patients with STEMI who underwent primary PCI and were treated during the COVID-19 period compared with a control period. These findings suggest that mature cardiac systems of care were able to maintain efficient care despite the challenges of the COVID-19 pandemic.

Review of pediatric emergency care and the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic posed new challenges in health care delivery for patients of all ages. These included inadequate personal protective equipment, workforce shortages, and unknowns related to a novel virus. Children have been uniquely impacted by COVID-19, both from the system of care and socially. In the initial surges of COVID-19, a decrease in pediatric emergency department (ED) volume and a concomitant increase in critically ill adult patients resulted in re-deployment of pediatric workforce to care for adult patients. Later in the pandemic, a surge in the number of critically ill children was attributed to multisystem inflammatory syndrome in children. This was an unexpected complication of COVID-19 and further challenged the health care system. This article reviews the impact of COVID-19 on the entire pediatric emergency care continuum, factors affecting ED care of children with COVID-19 infection, including availability of vaccines and therapeutics approved for children, and pediatric emergency medicine workforce innovations and/or strategies. Furthermore, it provides guidance to emergency preparedness for optimal delivery of care in future health-related crises.

Artificial intelligence to support out-of-hospital cardiac arrest care: A scoping review.

Background: Artificial intelligence (AI) has demonstrated significant potential in supporting emergency medical services personnel during out-of-hospital cardiac arrest (OHCA) care; however, the extent of research evaluating this topic is unknown. This scoping review examines the breadth of literature on the application of AI in early OHCA care. Methods: We conducted a search of PubMed®, Embase, and Web of Science in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Articles focused on non-traumatic OHCA and published prior to January 18th, 2023 were included. Studies were excluded if they did not use an AI intervention (including machine learning, deep learning, or natural language processing), or did not utilize data from the prehospital phase of care. Results: Of 173 unique articles identified, 54 (31%) were included after screening. Of these studies, 15 (28%) were from the year 2022 and with an increasing trend annually starting in 2019. The majority were carried out by multinational collaborations (20/54, 38%) with additional studies from the United States (10/54, 19%), Korea (5/54, 10%), and Spain (3/54, 6%). Studies were classified into three major categories including ECG waveform classification and outcome prediction (24/54, 44%), early dispatch-level detection and outcome prediction (7/54, 13%), return of spontaneous circulation and survival outcome prediction (15/54, 20%), and other (9/54, 16%). All but one study had a retrospective design. Conclusions: A small but growing body of literature exists describing the use of AI to augment early OHCA care.

The Management of Children and Youth With Pediatric Mental and Behavioral Health Emergencies.

Mental and behavioral health (MBH) emergencies in children and youth continue to increasingly affect not only the emergency department (ED), but the entire spectrum of emergency medical services for children, from prehospital services to the community. Inadequate community and institutional infrastructure to care for children and youth with MBH conditions makes the ED an essential part of the health care safety net for these patients. As a result, an increasing number of children and youth are referred to the ED for evaluation of a broad spectrum of MBH emergencies, from depression and suicidality to disruptive and aggressive behavior. However, challenges in providing optimal care to these patients include lack of personnel, capacity, and infrastructure, challenges with timely access to a mental health professional, the nature of a busy ED environment, and paucity of outpatient post-ED discharge resources. These factors contribute to prolonged ED stays and boarding, which negatively affects patient care and ED operations. Strategies to improve care for MBH emergencies, including systems level coordination of care, is therefore essential. The goal of this policy statement and its companion technical report is to highlight strategies, resources, and recommendations for improving emergency care delivery for pediatric MBH.

Pediatric emergency care coordinator workforce: A survey study.

Objectives: The appointment of pediatric emergency care coordinators (PECC) in emergency departments (EDs) enhances pediatric readiness, yet little is understood regarding this workforce. We describe PECC role characteristics, responsibilities, barriers, and threats to the role among a national cohort. Methods: We surveyed a sample of PECCs from all regions of the United States who participated in the Emergency Medical Services for Children PECC Workforce and Trauma Collaboratives (2021-2022). EDs were categorized by annual pediatric patient volume: low (<1800), medium (1800-4999), medium-high (5000-9999), and high (≥10,000). Trend tests were performed to explore the relationship between pediatric volume and PECC characteristics. Results: Among 187 PECCs, 114 (61.0%) responded. The majority (75.2%) identified as a nurse. There was a significant difference in median hours per week spent on PECC activities by pediatric volume ranging from a median of 2 hours (interquartile range [IQR] 0.0-2.3) for low pediatric volume to 16 hours (IQR 4.0-37.0) for high pediatric volume (P < 0.001). Most respondents reported more time was needed for PECC activities (58.4%), and desired additional training to support the role (70.8%). Most (74.6%) felt the PECC position should be paid, yet 30.7% reported the role was voluntary. The most frequently assigned responsibilities were education of staff (77.2%) and oversight of quality improvement (QI) efforts (72.8%). Conclusion: Characteristics of PECC workforce vary but PECC activities of education and QI work are common among all. There is a reported need for additional training and support. Further studies will determine the impact of PECC characteristics on pediatric readiness.

Racial and ethnic disparities in the provision of bystander CPR after witnessed out-of-hospital cardiac arrest in the United States.

OBJECTIVE: To evaluate the association between race/ethnicity and the odds of receiving bystander cardiopulmonary resuscitation (bCPR) after witnessed out-of-hospital cardiac arrest (OHCA). METHODS: For this cross-sectional retrospective study, data were obtained from the National Emergency Medical Services Information System database for adults (≥18 years) with a witnessed non-traumatic OHCA in the year 2021. Patients were separated into two groups including Black/Hispanic and White. The primary outcome was the odds of receiving bCPR. We excluded traumatic etiology, do-not-resuscitate orders, and arrest in a healthcare facility or wilderness location. Multiple logistic regression controlling for known covariates was utilized and analyses were stratified by public versus non-public location, median household income, and rural, suburban, or urban setting. RESULTS: A total of 64,007 witnessed OHCAs were included. When compared to White, the Black/Hispanic group were younger (62 vs 67 years) and more often female (40% vs 33%), in neighborhoods with the lowest median household income (31% vs 13%) and in an urban setting (92% vs 80%). Overall, bystander CPR rates were 60% and 67% for the Black/Hispanic and White groups, respectively. Multiple logistic regression stratified by OHCA location found that the Black/Hispanic group had a decreased odds of receiving bCPR compared to the White group both in the home (adjusted OR [aOR] 0.77; 95% CI 0.74-0.81) and in public (aOR 0.69; 95% CI 0.64-0.76). This difference persisted throughout neighborhoods of different socioeconomic status and across the rural-urban spectrum. CONCLUSIONS: Racial/ethnic disparities exist for Black and Hispanic persons in the odds of receiving bCPR after a witnessed non-traumatic OHCA regardless of public or private setting, neighborhood income level, or population density.

National Assessment of Pediatric Readiness of US Emergency Departments During the COVID-19 Pandemic.

Importance: The National Pediatric Readiness Project assessment provides a comprehensive evaluation of the readiness of US emergency departments (EDs) to care for children. Increased pediatric readiness has been shown to improve survival for children with critical illness and injury. Objectives: To complete a third assessment of pediatric readiness of US EDs during the COVID-19 pandemic, to examine changes in pediatric readiness from 2013 to 2021, and to evaluate factors associated with current pediatric readiness. Design, Setting, and Participants: In this survey study, a 92-question web-based open assessment of ED leadership in US hospitals (excluding EDs not open 24 h/d and 7 d/wk) was sent via email. Data were collected from May to August 2021. Main Outcomes and Measures: Weighted pediatric readiness score (WPRS) (range, 0-100, with higher scores indicating higher readiness); adjusted WPRS (ie, normalized to 100 points), calculated excluding points received for presence of a pediatric emergency care coordinator (PECC) and quality improvement (QI) plan. Results: Of the 5150 assessments sent to ED leadership, 3647 (70.8%) responded, representing 14.1 million annual pediatric ED visits. A total of 3557 responses (97.5%) contained all scored items and were included in the analysis. The majority of EDs (2895 [81.4%]) treated fewer than 10 children per day. The median (IQR) WPRS was 69.5 (59.0-84.0). Comparing common data elements from the 2013 and 2021 NPRP assessments demonstrated a reduction in median WPRS (72.1 vs 70.5), yet improvements across all domains of readiness were noted except in the administration and coordination domain (ie, PECCs), which significantly decreased. The presence of both PECCs was associated with a higher adjusted median (IQR) WPRS (90.5 [81.4-96.4]) compared with no PECC (74.2 [66.2-82.5]) across all pediatric volume categories (P < .001). Other factors associated with higher pediatric readiness included a full pediatric QI plan vs no plan (adjusted median [IQR] WPRS: 89.8 [76.9-96.7] vs 65.1 [57.7-72.8]; P < .001) and staffing with board-certified emergency medicine and/or pediatric emergency medicine physicians vs none (median [IQR] WPRS: 71.5 [61.0-85.1] vs 62.0 [54.3-76.0; P < .001). Conclusions and Relevance: These data demonstrate improvements in key domains of pediatric readiness despite losses in the health care workforce, including PECCs, during the COVID-19 pandemic, and suggest organizational changes in EDs to maintain pediatric readiness.

American Board of Emergency Medicine Report on Residency and Fellowship Training Information (2022-2023).

The American Board of Emergency Medicine gathers extensive background information on the Accreditation Council of Graduate Medical Education-accredited emergency medicine residency and fellowship programs and the residents and fellows training in those programs. We present the 2023 annual report on the status of physicians training in ACGME-accredited emergency medicine training programs in the United States.

Comparison of performance data between emergency medicine 1-3 and 1-4 program formats.

Objective: This study compares performance data from physicians completing 3-year versus 4-year emergency medicine residency training programs. Currently, there are 2 training formats and little is known about objective performance differences. Methods: This was a retrospective cross-sectional analysis of emergency residents and physicians. Multiple analyses were conducted comparing physicians' performances, including Accreditation Council of Graduate Medical Education Milestones and American Board of Emergency Medicine In-training Examination (ITE), Qualifying Examination (QE), Oral Certification Examination (OCE), and program extensions from 3-year and 4-year residency programs. Some confounding variables were not or could not be considered, such as rationale for medical students to choose one format over another, as well as application and final match rates. Results: Milestone scores are higher for emergency medicine 3 residents in 1-3 programs (3.51) versus emergency medicine 3 residents in 1-4 programs (3.07; P < 0.001, d = 1.47) and highest for emergency medicine 4 residents (3.67). There was no significant difference in program extension rates (emergency medicine 1-3, 8.1%; emergency medicine 1-4, 9.6%; P = 0.05, ω = 0.02). ITE scores were higher for emergency medicine 1, 2, and 3 residents from 1-3 programs and emergency medicine 4 residents from 1-4 programs scored highest. Mean QE score was slightly higher for emergency 1-3 physicians (83.55 vs 83.00; P < 0.01, d = 0.10). QE pass rate was higher for emergency 1-3 physicians (93.1% vs 90.8%; P < 0.001, ω = 0.08). Mean OCE score was slightly higher for emergency 1-4 physicians (5.67 vs 5.65; P = 0.03, d = -0.07) but did not reach a priori statistical significance (α < 0.01). OCE pass rate was also slightly higher for emergency 1-4 physicians (96.9% vs 95.5%; P = 0.06, ω = -0.07) but also non-significant. Conclusions: These results suggest that although performance measures demonstrate small differences between physicians from emergency medicine 1-3 and 1-4 programs, these differences are limited in their ability to make causal claims about performance on the basis of program format alone.

The Pediatric Education for Prehospital Professionals Course and the Pediatric Assessment Triangle: A 25-Year Retrospective.

The American Academy of Pediatrics established the Pediatric Education for Prehospital Professionals (PEPP) Course in 1998. A national PEPP Task Force rolled out the first courses in 2000, and PEPP rapidly became a foundational pediatric knowledge source in prehospital education. The backbone of the PEPP course is the pediatric assessment triangle (PAT), a simple assessment tool to help determine if an infant or child is "sick" or "not sick", to identify the likely type of pathophysiology, and to gauge the urgency for intervention. The PAT has been validated in multiple studies as a reliable tool for emergency triage and for guiding initial management of children in both prehospital and emergency settings. Over 400,000 emergency medical services clinicians have taken the PEPP course, and the PAT has been integrated into life support courses, emergency pediatrics training, and pediatric assessment protocols worldwide. We describe the creation and successful implementation of the first national prehospital pediatric emergency care course, including the integration and widespread dissemination of an innovative assessment paradigm for pediatric emergency care education and training.
