Deliberate Practice as an Effective Method for Reducing Diagnostic Error in Identifying Burn and Bruise Injuries Suspicious for an Abusive Injury.

OBJECTIVE: To examine the effectiveness of an education intervention for reducing physician diagnostic error in identifying pediatric burn and bruise injuries suspicious for abuse, and to determine case-specific variables associated with an increased risk of diagnostic error. STUDY DESIGN: This was a multicenter, prospective, cross-sectional study. A convenience sample of pediatricians and other front-line physicians who treat acutely injured children in the United States and Canada were eligible for participation. Using a web-based education and assessment platform, physicians deliberately practiced with a spectrum of 300 pediatric burn and bruise injury image-based cases. Participants were asked if there was a suspicion for abuse present or absent, were given corrective feedback after every case, and received summative diagnostic performance overall (accuracy), suspicion for abuse present (sensitivity), and absent (specificity). RESULTS: Of the 93/137 (67.9%) physicians who completed all 300 cases, there was a significant reduction in diagnostic error (initial 16.7%, final 1.6%; delta -15.1%; 95% CI -13.5, -16.7), sensitivity error (initial 11.9%, final 0.7%; delta -11.2%; 95% CI -9.8, -12.5), and specificity error (initial 23.3%, final 6.6%; delta -16.7%; 95% CI -14.8, -18.6). Based on 35 627 case interpretations, variables associated with diagnostic error included patient age, sex, skin color, mechanism of injury, and size and pattern of injury. CONCLUSIONS: The education intervention substantially reduced diagnostic error in differentiating the presence vs absence of a suspicion for abuse in children with burn and bruise injuries. Several case-based variables were associated with diagnostic error, and these data can be used to close specific skill gaps in this clinical domain.

Pediatric Sepsis in General Emergency Departments: Association Between Pediatric Sepsis Case Volume, Care Quality, and Outcome.

STUDY OBJECTIVE: To assess whether a general emergency department's (ED) annual pediatric sepsis volume increases the odds of delivering care concordant with Surviving Sepsis pediatric guidelines. METHODS: A retrospective cohort study of children <18 years with sepsis presenting to 29 general EDs. Emergency department and hospital data were abstracted from the medical records of 2 large health care systems, including all hospitals to which children were transferred. Guideline-concordant care was defined as intravenous antibiotics within 3 hours, intravenous fluid bolus within 3 hours, and lactate measured. The association between annual ED pediatric sepsis encounters and the probability of receiving guideline-concordant care was assessed. RESULTS: We included 1,527 ED encounters between January 1, 2015, and September 30, 2021. Three hundred and one (19%) occurred in 25 EDs with <10 pediatric sepsis encounters annually, 466 (31%) in 3 EDs with 11 to 100 pediatric sepsis encounters annually, and 760 (50%) in an ED with more than 100 pediatric sepsis encounters annually. Care was concordant in 627 (41.1%) encounters. In multivariable analysis, annual pediatric sepsis volume was minimally associated with the probability of guideline-concordant care (odds ratio 1.002 [95% confidence interval 1.001 to 1.00]). Care concordance increased from 23.1% in 2015 to 52.8% in 2021. CONCLUSION: Guideline-concordant sepsis care was delivered in 41% of pediatric sepsis cases in general EDs, and annual ED pediatric sepsis encounters had minimal association with the odds of concordant care. Care concordance improved over time. This study suggests that factors other than pediatric sepsis volume are important in driving care quality and identifying drivers of improvement is important for children first treated in general EDs.

Frequency, Type, and Degree of Potential Harm of Adverse Safety Events among Pediatric Emergency Medical Services Encounters.

BACKGROUND: Only 5-10% of emergency medical services (EMS) patients are children, and most pediatric encounters are low-acuity. EMS chart review has been used to identify adverse safety events (ASEs) in high-acuity and high-risk pediatric encounters. The objective of this work was to evaluate the frequency, type, and potential harm of ASEs in varied acuity pediatric EMS encounters. METHODS: This cross-sectional study evaluated pediatric (ages 0-18 years) prehospital records from 15 EMS agencies among three states (Colorado, Connecticut, and Rhode Island) between November 2019 and October 2021. Research associates used a previously validated tool to analyze electronic EMS and hospital records. Adverse safety events were recorded in six care categories, grouped into four levels for analysis: assessment/diagnosis/clinical decision-making, procedures, medication administration (including O2), and fluid administration, and defined across five types of ASEs: Unintended injuries or consequences, Near misses, Suboptimal actions, Errors, and Management complications (UNSEMs). Type and frequency of ASEs in each category were rated in three harm severities: Harm Unlikely, Mild/Temporary, or Permanent/Severe. Three physicians verified ASEs determined by research associates. Frequency of ASEs and harm likelihood are reported. RESULTS: Records for 508 EMS patients were reviewed, with 63 (12.4%) transported using lights and sirens. At least one clinical intervention beyond assessment/diagnosis/clinical decision-making was documented for 183 (36.1%, 95% CI: 31.8, 40.4) patients. A total of 162 ASEs were identified for 112 patients (22.1%, 95% CI: 18.5, 25.7). Suboptimal actions were the most frequent UNSEM (n = 66, 40.7%; 95% CI: 33.1, 48.3). For ASEs, (n = 162), the most frequent associations were with procedures 39.5% (95% CI: 32.0, 47.0) or assessment/diagnosis/clinical decision making, 32.1%, (95% CI: 24.9, 39.3). Among care categories, fluid administration was associated with significantly more UNSEMs (58.1%, 95% CI:53.8, 62.4). Most ASEs were determined to be 'Harm Unlikely' 62.4% (95% CI: 54.4, 70.4), with assessment/diagnosis/clinical decision making having significantly fewer ASEs with documented harm (22.4%, 95% CI: 10.7, 34.1) compared to other care categories. CONCLUSION: Over 20% of pediatric EMS encounters had an identified ASE, and most were unlikely to cause harm. Most frequent ASEs were likely to be associated with procedures and assessment/diagnosis/clinical decision-making.

Identification of Factors Associated with Return of Spontaneous Circulation after Pediatric Out-of-Hospital Cardiac Arrest Using Natural Language Processing.

INTRODUCTION: Prior studies examining prehospital characteristics related to return of spontaneous circulation (ROSC) in pediatric out-of-hospital cardiac arrest (OHCA) are limited to structured data. Natural language processing (NLP) could identify new factors from unstructured data using free-text narratives. The purpose of this study was to use NLP to examine EMS clinician free-text narratives for characteristics associated with prehospital ROSC in pediatric OHCA. METHODS: This was a retrospective analysis of patients ages 0-17 with OHCA in 2019 from the ESO Data Collaborative. We performed an exploratory analysis of EMS narratives using NLP with an a priori token library. We then constructed biostatistical and machine learning models and compared their performance in predicting ROSC. RESULTS: There were 1,726 included EMS encounters for pediatric OHCA; 60% were male patients, and the median age was 1 year (IQR 0-9). Most cardiac arrest events (61.3%) were unwitnessed, 87.3% were identified as having medical causes, and 5.9% had initial shockable rhythms. Prehospital ROSC was achieved in 23.1%. Words most positively correlated with ROSC were "ROSC" (r = 0.42), "pulse" (r = 0.29), "drowning" (r = 0.13), and "PEA" (r = 0.12). Words negatively correlated with ROSC included "asystole" (r = -0.25), "lividity" (r = -0.14), and "cold" (r = -0.14). The terms "asystole," "pulse," "no breathing," "PEA," and "dry" had the greatest difference in frequency of appearance between encounters with and without ROSC (p < 0.05). The best-performing model for predicting prehospital ROSC was logistic regression with random oversampling using free-text data only (area under the receiver operating characteristic curve 0.92). CONCLUSIONS: EMS clinician free-text narratives reveal additional characteristics associated with prehospital ROSC in pediatric OHCA. Incorporating those terms into machine learning models of prehospital ROSC improves predictive ability. Therefore, NLP holds promise as a tool for use in predictive models with the goal to increase evidence-based management of pediatric OHCA.

Prehospital Recognition and Management of Pediatric Sepsis: A Qualitative Assessment.

BACKGROUND AND PURPOSE: Sepsis is a life-threatening disease in children and is a leading cause of morbidity and mortality. Early prehospital recognition and management of children with sepsis may have significant effects on the timely resuscitation of this high-risk clinical condition. However, the care of acutely ill and injured children in the prehospital setting can be challenging. This study aims to understand barriers, facilitators, and attitudes regarding recognition and management of pediatric sepsis in the prehospital setting. METHODS: This was a qualitative study of EMS professionals participating in focus groups using a grounded theory-based design to gather information on recognition and management of septic children in the prehospital setting. Focus groups were held for EMS administrators and medical directors. Separate focus groups were held for field clinicians. Focus groups were conducted via video conference until saturation of ideas was reached. Using consensus methodology, transcripts were coded in an iterative process. Data were then organized into positive and negative factors based on the validated PRECEDE-PROCEED model for behavioral change. RESULTS: Thirty-eight participants in six focus groups identified nine environmental factors, 21 negative factors, and 14 positive factors pertaining to recognition and management of pediatric sepsis. These findings were organized into the PRECEDE-PROCEED planning model. Pediatric sepsis guidelines were identified as positive factors when they did exist and negative factors when they were complicated or did not exist. Six interventions were identified by participants. These include raising awareness of pediatric sepsis, increasing pediatric education, receiving feedback on prehospital encounters, increasing pediatric exposure and skills training, and improving dispatch information. CONCLUSION: This study fills a gap by examining barriers and facilitators to prehospital diagnosis and management of pediatric sepsis. Using the PRECEDE-PROCEED model, nine environmental factors, 21 negative factors, and 14 positive factors were identified. Participants identified six interventions that could create the foundation to improve prehospital pediatric sepsis care. Policy changes were suggested by the research team based on the results of this study. These interventions and policy changes provide a roadmap for improving care in this population and lay the groundwork for future research.

Pediatric Emergency Care Coordination in EMS Agencies: Findings of a Multistate Learning Collaborative.

BACKGROUND: In 2017, the Health Resources and Services Administration's Maternal Child and Health Bureau's Emergency Medical Services for Children program implemented a performance measure for State Partnership grants to increase the percentage of EMS agencies within each state that have designated individuals who coordinate pediatric emergency care, also called a pediatric emergency care coordinator (PECC). The PECC Learning Collaborative (PECCLC) was established to identify best practices to achieve this goal. This study's objective is to report on the structure and outcomes of the PECCLC conducted among nine states. METHODS: This study used quantitative and qualitative methods to evaluate outcomes from the PECCLC. Participating state representatives engaged in a 6-month collaborative that included monthly learning sessions with subject matter experts and support staff and concluded with a two-day in-person meeting. Outcomes included reporting the number of PECCs recruited, identifying barriers and enablers to PECC recruitment, characterizing best practices to support PECCs, and identifying barriers and enablers to enhance and sustain the PECC role. Outcomes were captured by self-report from participating state representatives and longitudinal qualitative interviews conducted with representative PECCs at 6 and 18 months after conclusion of the PECCLC. RESULTS: During the 6-month collaborative, states recruited 341 PECCs (92% of goal). Follow up at 5 months post-collaborative revealed an additional recruitment of 184 for a total of 525 PECCs (142% of the goal). Feedback from state representatives and PECCs revealed the following barriers: competition from other EMS responsibilities, budgetary constraints, lack of incentive for agencies to create the position, and lack of requirement for establishing the role. Enablers identified included having an EMS agency recognition program that includes the PECC role, train-the-trainer programs, and inclusion of the PECC role in agency licensure requirements. Longitudinal interviews with PECCs identified that the most common activity associated with their role was pediatric-specific education and the most important need for PECC success was agency-level support. CONCLUSION: Over the 6-month Learning Collaborative, nine states were successful in recruiting a substantial number of PECCs. Financial and time constraints were significant barriers to statewide PECC recruitment, yet these can be potentially addressed by EMS agency recognition programs.

Impact of Race and Ethnicity on Emergency Medical Services Administration of Opioid Pain Medications for Injured Children.

BACKGROUND: Treatment with analgesics for injured children is often not provided or delayed during prehospital transport. OBJECTIVE: Our aim was to evaluate racial and ethnic disparities with the use of opioids during transport of injured children. METHODS: We conducted a prospective study of injured children transported to 1 of 10 emergency departments from July 2019 to April 2020. Emergency medical services (EMS) providers were surveyed about prehospital pain interventions during transport. Our primary outcome was the use of opioids. We performed multivariate regression analyses to evaluate the association of patient demographic characteristics (race, ethnicity, age, and gender), presence of a fracture, EMS provider type (Advanced Life Support [ALS] or non-ALS) and experience (years), and study site with the use of opioids. RESULTS: We enrolled 465 patients; 19% received opioids during transport. The adjusted odds ratios (AORs) for Black race and Hispanic ethnicity were 0.5 (95% CI 0.2-1.2) and 0.4 (95% CI 0.2-1.3), respectively. The presence of a fracture (AOR 17.0), ALS provider (AOR 5.6), older patient age (AOR 1.1 for each year), EMS provider experience (AOR 1.1 for each year), and site were associated with receiving opioids. CONCLUSIONS: There were no statistically significant associations between race or ethnicity and use of opioids for injured children. The presence of a fracture, ALS provider, older patient age, EMS provider experience, and site were associated with receiving opioids.

Impact of prehospital pediatric asthma management protocol adherence on clinical outcomes.

OBJECTIVE: To evaluate the frequency of EMS protocol non-adherence during pediatric asthma encounters and its association with emergency department (ED) length of stay (LOS) and hospital admission. METHODS: This is a retrospective review of asthma encounters aged 2-17 years transported by EMS to a pediatric ED from 2012 to 2017. Our primary outcome was hospital admission based on prehospital protocol adherence defined as: (1) bronchodilator administration, (2) treatment of hypoxia with oxygen, or (3) administration of intramuscular (IM) epinephrine in encounters with high severity of distress. Multivariable logistic regression estimated the association between protocol non-adherence and hospital admission. RESULTS: During the study period, 290 EMS encounters met inclusion criteria. Median age was 9 years (IQR 5-12), 63% were male, 40% had moderate to severe exacerbations, and 24% were admitted. Protocol non-adherence occurred in 32% of encounters with failure to administer bronchodilators in 27% and failure to administer IM epinephrine when indicated in 83%. Prehospital steroids were administered in 8% of encounters. After adjusting for covariates, protocol non-adherence was not statistically associated with likelihood of inpatient admission (OR 1.3; 95% CI: 0.6-2.6). CONCLUSIONS: Among prehospital pediatric asthma encounters, EMS protocol non-adherence is common but not associated with a higher frequency of hospital admission. Hospital admission was associated with acute exacerbation severity suggesting further research is needed to develop a valid prehospital asthma severity assessment scoring tool.Supplemental data for this article can be accessed at publisher's website.

A Novel Use of NEMSIS to Create a PECARN-Specific EMS Patient Registry.

Background: Research networks need access to EMS data to conduct pilot studies and determine feasibility of prospective studies. Combining data across EMS agencies is complicated and costly. Leveraging the National EMS Information System (NEMSIS) to extract select agencies' data may be an efficient and cost-effective method of providing network-level data. Objective: Describe the process of creating a Pediatric Emergency Care Applied Research Network (PECARN) specific NEMSIS data set and determine if these data were nationally representative. Methods: We established data use agreements (DUAs) with EMS agencies participating in PECARN to allow for agency identification through NEMSIS. Using 2019 NEMSIS version 3.4.0 data for EMS events with patients 18 years old and younger, we compared PECARN NEMSIS data to national NEMSIS data. Analyzed variables were selected for their ability to characterize events. No statistical analyses were utilized due to the large sample, instead, differences of ±5% were deemed clinically meaningful. Results: DUAs were established for 19 EMS agencies, creating a PECARN data set with 305,188 EMS activations of which 17,478 (5.7%) were pediatric. Of the pediatric activations, 17,140 (98.1%) were initiated through 9-1-1 and 9,487 (55.4%) resulted in transport by the documenting agency. The national data included 36,288,405 EMS activations of which 2,152,849 (5.9%) were pediatric. Of the pediatric activations 1,704,141 (79.2%) were initiated through 9-1-1 and 1,055,504 (61.9%) were transported by the documenting agency. Age and gender distributions were similar between the two groups, but the PECARN-specific data under-represents Black and Latinx patients. Comparison of EMS provider primary impressions revealed that three of the five most common were similar with injury being the most prevalent for both data sets along with mental/behavioral health and seizure. Conclusion: We demonstrated that NEMSIS can be leveraged to create network specific data sets. PECARN's EMS data were similar to the national data, though racial/ethnic minorities and some primary impressions may be under-represented. Additionally, more EMS activations in PECARN study areas originated through 9-1-1 but fewer were transported by the documenting agency. This is likely related to the type of participating agencies, their ALS response level, and the diversity of the communities they serve.

Emergency Medical Services Provider Acceptance of and Attitudes About Pediatric SimBox Simulations.

OBJECTIVE: SimBox simulations allow for high-frequency open-access health care education, overcoming cost and resource barriers. Prehospital paramedics and emergency medical technician (EMT) care for children infrequently. In this study, prehospital providers evaluated pediatric SimBox simulations. METHODS: This was a cross-sectional study of EMS professionals participating in a series of simulations conducted in a larger project assessing improvement of the quality of pediatric care in the prehospital setting. Participants were teams of two, which comprised a paramedic/paramedic, paramedic/EMT, or 2 EMTs. The simulations used facilitator resources, debriefing prompts, video depictions of patients and vital signs, and a low-fidelity manikin. Pediatric emergency care coordinators, EMS training officers, and/or emergency physicians facilitated simulations of seizure, sepsis with respiratory failure, and child abuse, followed by debriefings. Participants completed an online survey after the simulation and rated it in 4 domains: prebriefing, scenario content, debriefing, and overall. Ratings were trifold: "strongly agree," "somewhat agree," or "do not agree." Data were analyzed by case type, participant type, location, participant reaction to simulation elements, and the debriefing. Net Promoter Scores were calculated to assess participant endorsement of SimBox. RESULTS: There were 121 participants: 103 (87%) were paramedics, and 18 (13%) were EMTs. Participant agreement of simulation benefit for clinical practice was high, for example, "I am more confident in my ability to prioritize care and interventions" (98.4% strongly or somewhat agree), and 99.2% of participants agreed the postsimulation debriefing with facilitators "provided opportunities to self-reflect on my performance during simulation." Overall, 97.5% strongly or somewhat agreed that the simulations "improved my comfort in pediatric acute care." Net Promoter Score showed 65.3% were promoters of and 24% were passive about SimBox. CONCLUSION: SimBox simulations are associated with improved self-efficacy of prehospital care providers for care of acutely ill or injured children. The majority promotes SimBox as a learning tool.

Modified Delphi Method Derivation of the FAMILY (Family Assessment of Medical Interventions & Liaisons with the Young) EMS Instrument.

BACKGROUND: Though family satisfaction with prehospital care is a surrogate for quality and patient outcomes, there are no tools available to measure family satisfaction. OBJECTIVE: To develop the EMS Family Assessment of Medical Interventions & Liaisons with the Young (FAMILY) instrument. METHODS: Components of family experiences with pediatric prehospital care were identified with a modified Delphi method. The expert panel included Emergency Medical Technicians, paramedics, family representatives, and EMS leaders from Colorado, Connecticut, and Rhode Island. An online survey was used to assess proposed questions from each of five candidate domains from national guidelines, including Safety, Communication, Family Presence, Cultural Awareness, Children with Special Healthcare Needs and Overall Satisfaction. Round-1 items were scored on a five-point Likert scale. Inclusion in the final instrument required 70% agreement ranking items as "include" or "definitely include." In Round-2, participants assessed proposed refinements. This resulted in FAMILY Version-1, with sections for family members and EMS care providers. EMSC Family Action Network (FAN) representatives evaluated the FAMILY, leading to Version-2. Suggestions from the national FAN about content, clarity, and whether the instrument captured their experiences with pediatric EMS care led to the final FAMILY version. Bilingual speakers translated the instrument into Spanish, while assessing the content for semantic, idiomatic, experiential, and conceptual equivalence between the English and Spanish versions. RESULTS: There were 22 experts in Round-1, and 20 continued into Round-2 .The Delphi process yielded 12 questions in six domains with 14 recommended modifications. Two questions were excluded. Five domains reached 70% agreement in Round-1. Cultural Awareness reached 75% agreement after Round-2. Six FAN representatives evaluated Version-1, leading to changes for clarity, content and cultural sensitivity. Seventeen FAN representatives evaluated Version-2 leading to additional refinement. The assessment of the equivalence between the English and Spanish survey versions resulted in changes in the Spanish language content for equivalent meaning. CONCLUSION: A panel of EMS and family stakeholders successfully developed an instrument to assess family satisfaction with pediatric EMS care. Further validation is required in a large respondent population. Assessing family satisfaction with pediatric EMS encounters is an important step toward improving prehospital care.

Documentation of Child Maltreatment by Emergency Medical Services in a National Database.

BACKGROUND: Child abuse and neglect (CAN) has an estimated annual incidence of 1.46% among those ≤3 years old. Prehospital providers (PHPs) report difficulties identifying CAN and the frequency in which PHPs document CAN during prehospital encounters of young children is not known. OBJECTIVE: To report the percentage of CAN documentation by PHPs during encounters among children ≤3 years in a national dataset and describe the characteristics of this population. METHODS: This is an analysis of concurrent cases in the 2017-18 National Emergency Medical Services Information System database. We identified children ≤3 years old with ICD-10-CM codes specific for CAN including codes for physical and sexual abuse as well as neglect. We examined patient demographics including race, gender, Emergency Medical Services (EMS) primary and secondary impression, associated symptoms, anatomic location of chief complaint, and cause of injury. Our primary outcome is the percentage of CAN reported as an EMS primary or secondary impression; secondary outcomes include proportion of children with each subtype of abuse, the description of patients by demographic information, anatomic location of injury, and associated symptoms. RESULTS: There were 498,555 for children ≤3 years old, of which 522 had an impression of CAN (0.10%). Within our cohort, 43% were <1 year of age, 51% were male. The most common anatomic location of injury was general/global (29.7%), followed by head (23.5%) and extremity (14%). The most common symptoms reported by PHPs are those associated with injury including codes for injury, burn, fracture, cutaneous findings, hemorrhage, or pain (n = 244, 63%). Pain is the most commonly reported symptom (n = 110, 21%). Few encounters specified vomiting, seizure, or disordered breathing as symptoms (1%, 1%, and 5.4%, respectively). Interestingly, 28.2% (27/124) of cases in our cohort were related to sexual abuse. CONCLUSIONS: The percentage of PHP documentation of CAN among children ≤3 years of age is very low. Among those with an EMS primary impression of CAN, documentation is primarily associated with findings of injury whereas documentation of nonspecific symptoms such as vomiting and seizure is infrequent. These findings suggest that recognition of abuse primarily occurs in young patients with overt signs of trauma.

Medication Dosing Safety for Pediatric Patients: Recognizing Gaps, Safety Threats, and Best Practices in the Emergency Medical Services Setting. A Position Statement and Resource Document from NAEMSP.

BACKGROUND: Millions of patients receive medications in the Emergency Medical Services (EMS) setting annually, and dosing safety is critically important. The need for weight-based dosing in pediatric patients and variability in medication concentrations available in the EMS setting may require EMS providers to perform complex calculations to derive the appropriate dose to deliver. These factors can significantly increase the risk for harm when dose calculations are inaccurate or incorrect. METHODS: We conducted a scoping review of the EMS, interfacility transport and emergency medicine literature regarding pediatric medication dosing safety. A priori, the authors identified four research topics: (1) what are the greatest safety threats that result in significant dosing errors that potentially result in harm to patients, (2) what practices or technologies are known to enhance dosing safety, (3) can data from other settings be extrapolated to the EMS environment to inform dosing safety, and (4) what impact could standardization of medication formularies have on enhancing dosing safety. To address these topics, 17 PICO (Patient, Intervention, Comparison, Outcome) questions were developed and a literature search was performed. RESULTS: After applying exclusion criteria, 70 articles were reviewed. The methods for the investigation, findings from these articles and how they inform EMS medication dosing safety are summarized here. This review yielded 11 recommendations to improve safety of medication delivery in the EMS setting. CONCLUSION: These recommendations are summarized in the National Association of EMS Physicians® position statement: Medication Dosing Safety for Pediatric Patients in Emergency Medical Services.

Child Abuse Recognition Training for Prehospital Providers Using Deliberate Practice.

BACKGROUND: In most states, prehospital professionals (PHPs) are mandated reporters of suspected abuse but cite a lack of training as a challenge to recognizing and reporting physical abuse. We developed a learning platform for the visual diagnosis of pediatric abusive versus non-abusive burn and bruise injuries and examined the amount and rate of skill acquisition. METHODS: This was a prospective cross-sectional study of PHPs participating in an online educational intervention containing 114 case vignettes. PHPs indicated whether they believed a case was concerning for abuse and would report a case to child protection services. Participants received feedback after submitting a response, permitting deliberate practice of the cases. We describe learning curves, overall accuracy, sensitivity (diagnosis of abusive injuries) and specificity (diagnosis of non-abusive injuries) to determine the amount of learning. We performed multivariable regression analysis to identify specific demographic and case variables associated with a correct case interpretation. After completing the educational intervention, PHPs completed a self-efficacy survey on perceived gains in their ability to recognize cutaneous signs of abuse and report to social services. RESULTS: We enrolled 253 PHPs who completed all the cases; 158 (63.6%) emergency medical technicians (EMT), 95 (36.4%) advanced EMT and paramedics. Learning curves demonstrated that, with one exception, there was an increase in learning for participants throughout the educational intervention. Mean diagnostic accuracy increased by 4.9% (95% CI 3.2, 6.7), and the mean final diagnostic accuracy, sensitivity, and specificity were 82.1%, 75.4%, and 85.2%, respectively. There was an increased odds of getting a case correct for bruise versus burn cases (OR = 1.4; 95% CI 1.3, 1.5); if the PHP was an Advanced EMT/Paramedic (OR = 1.3; 95% CI 1.1, 1.4) ; and, if the learner indicated prior training in child abuse (OR = 1.2; 95% CI 1.0, 1.3). Learners indicated increased comfort in knowing which cases should be reported and interpreting exams in children with cutaneous injuries with a median Likert score of 5 out of 6 (IQR 5, 6). CONCLUSION: An online module utilizing deliberate practice led to measurable skill improvement among PHPs for differentiating abusive from non-abusive burn and bruise injuries.

Recommended Essential Equipment for Basic Life Support and Advanced Life Support Ground Ambulances 2020: A Joint Position Statement.

In continued support of establishing and maintaining a foundation for standards of care, our organizations remain committed to periodic review and revision of this position statement. This latest revision was created based on a structured review of the National Model EMS Clinical Guidelines Version 2.2 in order to identify the equipment items necessary to deliver the care defined by those guidelines. In addition, in order to ensure congruity with national definitions of provider scope of practice, the list is differentiated into BLS and ALS levels of service utilizing the National Scope of Practice-defined levels of Emergency Medical Responder (EMR) and Emergency Medical Technician (EMT) as BLS, and Advanced EMT (AEMT) and Paramedic as ALS. Equipment items listed within each category were cross-checked against recommended scopes of practice for each level in order to ensure they were appropriately dichotomized to BLS or ALS levels of care. Some items may be considered optional at the local level as determined by agency-defined scope of practice and applicable clinical guidelines. In addition to the items included in this position statement our organizations agree that all EMS service programs should carry equipment and supplies in quantities as determined by the medical director and appropriate to the agency's level of care and available certified EMS personnel and as established in the agency's approved protocols.

Public Perceptions on Why Women Receive Less Bystander Cardiopulmonary Resuscitation Than Men in Out-of-Hospital Cardiac Arrest.

BACKGROUND: Women who suffer an out-of-hospital cardiac arrest receive bystander cardiopulmonary resuscitation (CPR) less often than men. Understanding public perceptions of why this occurs is a necessary first step toward equitable application of this potentially life-saving intervention. METHODS: We conducted a national survey of members of the public using Mechanical Turk, Amazon's crowdsourcing platform, to determine reasons why women might receive bystander CPR less often than men. Eligible participants were adults (≥18 years) located in the United States. Responses were excluded if the participant was not able to define CPR correctly. Participants were asked to answer the following free-text question: "Do you have any ideas on why women may be less likely to receive CPR than men when they collapse in public?" Descriptive statistics were used to define the cohort. The free-text response was coded using open coding, and major themes were identified via classical content analysis. RESULTS: In total, 548 subjects were surveyed. Mean age was 38.8 years, and 49.8% were female. Participants were geographically distributed as follows: 18.5% West, 9.2% Southwest, 22.0% Midwest, 27.5% Southeast, and 22.9% Northeast. After analysis, 3 major themes were detected for why the public perceives that women receive less bystander CPR. They include the following: (1) sexualization of women's bodies; (2) women are weak and frail and therefore prone to injury; and (3) misperceptions about women in acute medical distress. Overall, 41.9% (227) were trained in CPR while 4.4% reported having provided CPR in a medical emergency. CONCLUSIONS: Members of the general public perceive fears about inappropriate touching, accusations of sexual assault, and fear of causing injury as inhibiting bystander CPR for women. Educational and policy efforts to address these perceptions may reduce the sex differences in the application of bystander CPR.

Appropriate Needle Length for Emergent Pediatric Needle Thoracostomy Utilizing Computed Tomography.

Objective: Needle thoracostomy is a life-saving procedure. Advanced Trauma Life Support guidelines recommend insertion of a 5 cm, 14-gauge needle for pneumothorax decompression. High-risk complications can arise if utilizing an inappropriate needle size. No study exist evaluating appropriate needle length in pediatric patients. Utilizing computed tomography (CT), we determined the needle length required to access the pleural cavity in children matched to Broselow™ Pediatric Emergency Tape color. Methods: Three investigators reviewed chest CTs of children <13 years of age obtained between 2010 and 2015. Patient exclusions included those with a chest wall mass, muscle disease, pectus deformity, anasarca, prior open thoracotomy, inadequate imaging, or missing height documentation. We established 4 groups based upon Broselow™ color as determined by recorded height. Investigators, trained by a pediatric board-certified radiologist, obtained standardized CT measurements of chest wall thickness at 4 points: right/left second intercostal space at the midclavicular line (ICS-MCL) and right/left fourth intercostal space in the anterior axillary line (ICS-AAL). Our outcome was the median chest wall thickness and 95% confidence intervals for each Broselow grouping and anatomic site. Results: A total of 273 chest CTs were reviewed, of which 23 were excluded, for a resultant study population of 250 scans and 498 total measurements. Median patient age was 4 years, 52.8% were male. Children measuring Broselow Gray/Pink (<68 cm), had a median chest wall thickness at the 2nd ICS-MCL of 1.57 cm (95% CI 1.42 cm, 1.72 cm), 4th ICS-AAL 1.67 cm (95% CI 1.48 cm, 1.86 cm). Broselow Red/Purple (68.1-90 cm): 2nd ICS-MCL of 1.96 cm (95% CI 1.84 cm, 2.08 cm), 4th ICS-AAL 1.73 cm (95% CI 1.62 cm, 1.84 cm). Broselow Yellow/White (90.1-115cm): 2nd ICS-MCL of 2.12 cm (95% CI 2.03 cm, 1.22 cm), 4th ICS-AAL 1.91 cm (95% CI 1.8 cm, 2.01 cm). Broselow Blue/Orange/Green (>115.1 cm): 2nd ICS-MCL of 2.45 cm (95% CI 2.3 cm, 2.6 cm), 4th ICS-AAL 2.19cm (95% CI 2.02 cm, 2.36 cm). Conclusion: Median chest wall thickness varies little by height or location in children <13 years of age. The standard 5-cm needle is twice the chest wall thickness of most children. Commercially available 14 g or 16 g standard-length 3.8 cm (1½ inch) needles are of adequate length to access the pleural cavity, regardless of height as measured by Broselow LBT.

Challenges in Statewide Implementation of a Prehospital Evidence-Based Guideline: An Assessment of Barriers and Enablers in Five States.

BACKGROUND: Individual states, regions, and local emergency medical service (EMS) agencies are responsible for the development and implementation of prehospital patient care protocols. Many states lack model prehospital guidelines for managing common conditions. Recently developed national evidence-based guidelines (EBGs) may address this gap. Barriers to statewide dissemination and implementation of model guidelines have not been studied. The objective of this study was to examine barriers and enablers to dissemination and implementation of an evidence-based guideline for traumatic pain management across 5 states. METHODS: This study used mixed methods to evaluate the statewide dissemination and implementation of a prehospital EBG. The guideline provided pain assessment tools, recommended opiate medication dosing, and indications and contraindications for analgesia. Participating states were provided an implementation toolkit, standardized training materials, and a state-specific implementation plan. Outcomes were assessed via an electronic self-assessment tool in which states reported barriers and enablers to dissemination and implementation and information about changes in pain management practices in their states after implementation of the EBG. RESULTS: Of the 5 participating states, 3 reported dissemination of the guideline, one through a state model guideline process and 2 through regional EMS systems. Two states did not disseminate or implement the guideline. Of these, one state chose to utilize a locally developed guideline, and the other state did not perform guideline dissemination at the state level. Barriers to state implementation were the lack of authority at the state level to mandate protocols, technical challenges with learning management systems, and inability to track and monitor training and implementation at the agency level. Enablers included having a state/regional EMS office champion and the availability of an implementation toolkit. No participating states demonstrated an increase in opioid delivery to patients during the study period. CONCLUSION: Statewide dissemination and implementation of an EBG is complex with many challenges. Future efforts should consider the advantages of having statewide model or mandatory guidelines and the value of local champions and be aware of the challenges of a statewide learning management system and of tracking the success of implementation efforts.

Utilization of Intravenous Catheters by Prehospital Providers during Pediatric Transports.

INTRODUCTION: Prehospital intravenous (IV) access in children may be difficult and time-consuming. Emergency Medical Service (EMS) protocols often dictate IV placement; however, some IV catheters may not be needed. The scene and transport time associated with attempting IV access in children is unknown. The objective of this study is to examine differences in scene and transport times associated with prehospital IV catheter attempt and utilization patterns of these catheters during pediatric prehospital encounters. METHODS: Three non-blinded investigators abstracted EMS and hospital records of children 0-18 years of age transported by EMS to a pediatric emergency department (ED). We compared patients in which prehospital IV access was attempted to those with no documented attempt. Our primary outcome was scene time. Secondary outcomes include utilization of the IV catheter in the prehospital and ED settings and a determination of whether the catheter was indicated based on a priori established criteria (prehospital IV medication administration, hypotension, GCS < 13, and ICU admission). RESULTS: We reviewed 1,138 records, 545 meeting inclusion criteria. IV catheter placement was attempted in 27% (n = 149) with success in 77% (n = 111). There was no difference in the presence of hypotension or median GCS between groups. Mean scene time (12.5 vs. 11.8 minutes) and transport time (16.9 vs. 14.6 minutes) were similar. Prehospital IV medications were given in 38.7% (43/111). One patient received a prehospital IV medication with no alternative route of administration. Among patients with a prehospital IV attempt, 31% (46/149) received IV medications in the ED and 23% (34/396) received IV fluids in the ED. Mean time to use of the IV in the ED was 70 minutes after arrival. Patients with prehospital IV attempt were more likely to receive IV medication within 30 minutes of ED arrival (39.1% vs. 19.0%, p = 0.04). Overall, 34.2% of IV attempts were indicated. CONCLUSIONS: Prehospital IV catheter placement in children is not associated with an increase in scene or transport time. Prehospital IV catheters were used in approximately one-third of patients. Further study is needed to determine which children may benefit most from IV access in the prehospital setting.
