RESUMO
OBJECTIVE: The aim of this study was to evaluate the association of annual trauma patient volume on outcomes for emergency medical services (EMS) agencies. BACKGROUND: Regionalization of trauma care saves lives. The underlying concept driving this is a volume-outcome relationship. EMS are the entry point to the trauma system, yet it is unknown if a volume-outcome relationship exists for EMS. METHODS: A retrospective analysis of prospective cohort including 8 trauma centers and 20 EMS air medical and metropolitan ground transport agencies. Patients 18 to 90 years old with injury severity scores ≥9 transported from the scene were included. Patient and agency-level risk-adjusted regression determined the association between EMS agency trauma patient volume and early mortality. RESULTS: A total of 33,511 were included with a median EMS agency volume of 374 patients annually (interquartile range: 90-580). Each 50-patient increase in EMS agency volume was associated with 5% decreased odds of 6-hour mortality (adjusted odds ratio=0.95; 95% CI: 0.92-0.99, P =0.03) and 3% decreased odds of 24-hour mortality (adjusted odds ratio=0.97; 95% CI: 0.95-0.99, P =0.04). Prespecified subgroup analysis showed EMS agency volume was associated with reduced odds of mortality for patients with prehospital shock, requiring prehospital airway placement, undergoing air medical transport, and those with traumatic brain injury. Agency-level analysis demonstrated that high-volume (>374 patients/year) EMS agencies had a significantly lower risk-standardized 6-hour mortality rate than low-volume (<374 patients/year) EMS agencies (1.9% vs 4.8%, P <0.01). CONCLUSIONS: A higher volume of trauma patients transported at the EMS agency level is associated with improved early mortality. Further investigation of this volume-outcome relationship is necessary to leverage quality improvement, benchmarking, and educational initiatives.

Introduction: There are disparities in multiple aspects of pediatric asthma care; however, prehospital care disparities are largely undescribed. This study's objective was to examine racial and geographic disparities in emergency medical services (EMS) medication administration to pediatric patients with asthma. Methods: This is a substudy of the Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial, which includes data from pediatric asthma patients ages 2-18 years. We examined rates of EMS administration of systemic corticosteroids and inhaled bronchodilators by patient race. We geocoded EMS scene addresses, characterized the locations' neighborhood-based conditions and resources relevant to children using the Child Opportunity Index (COI) 2.0, and analyzed associations between EMS scene address COI with medications administered by EMS. Results: A total of 765 patients had available racial data and 825 had scene addresses that were geocoded to a COI. EMS administered at least 1 bronchodilator to 84.7% (n = 492) of non-White patients and 83.2% of White patients (n = 153), P = 0.6. EMS administered a systemic corticosteroid to 19.4% (n = 113) of non-White patients and 20.1% (n = 37) of White patients, P = 0.8. There was a significant difference in bronchodilator administration between COI categories of low/very low versus moderate/high/very high (85.0%, n = 485 vs. 75.9%, n = 192, respectively, P = 0.003). Conclusions: There were no racial differences in EMS administration of medications to pediatric asthma patients. However, there were significantly higher rates of EMS bronchodilator administration for encounters in low/very low COIs. That latter finding may reflect inequities in asthma exacerbation severity for patients living in disadvantaged areas.
RESUMO
INTRODUCTION: Pediatric asthma exacerbations are a common cause of emergency medical services (EMS) encounters. Bronchodilators and systemic corticosteroids are mainstays of asthma exacerbation therapy, yet data on the efficacy of EMS administration of systemic corticosteroids are mixed. This study's objective was to assess the association between EMS administration of systemic corticosteroids to pediatric asthma patients on hospital admission rates based on asthma exacerbation severity and EMS transport intervals. METHODS: This is a sub-analysis of the Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial (EASI AS ODT). EASI AS ODT is a non-randomized, stepped wedge, observational study examining outcomes one year before and one year after seven EMS agencies incorporated an oral systemic corticosteroid option into their protocols for the treatment of pediatric asthma exacerbations. We included EMS encounters for patients ages 2-18 years confirmed by manual chart review to have asthma exacerbations. We compared hospital admission rates across asthma exacerbation severities and EMS transport intervals using univariate analyses. We geocoded patients and created maps to visualize the general trends of patient characteristics. RESULTS: A total of 841 pediatric asthma patients met inclusion criteria. While most patients were administered inhaled bronchodilators by EMS (82.3%), only 21% received systemic corticosteroids, and only 19% received both inhaled bronchodilators and systemic corticosteroids. Overall, there was no significant difference in hospitalization rates between patients who did and did not receive systemic corticosteroids from EMS (33% vs. 32%, p = 0.78). However, although not statistically significant, for patients who received systemic corticosteroids from EMS, there was an 11% decrease in hospitalizations for mild exacerbation patients and a 16% decrease in hospitalizations for patients with EMS transport intervals greater than 40 min. CONCLUSION: In this study, systemic corticosteroids were not associated with a decrease in hospitalizations of pediatric patients with asthma overall. However, while limited by small sample size and lack of statistical significance, our results suggest there may be a benefit in certain subgroups, particularly patients with mild exacerbations and those with transport intervals longer than 40 min. Given the heterogeneity of EMS agencies, EMS agencies should consider local operational and pediatric patient characteristics when developing standard operating protocols for pediatric asthma.

INTRODUCTION: Effective trauma system organization is crucial to timely access to care and requires accurate understanding of injury and resource locations. Many systems rely on home zip codes to evaluate geographic distribution of injury; however, few studies have evaluated the reliability of home as a proxy for incident location after injury. METHODS: We analyzed data from a multicenter prospective cohort collected from 2017 to 2021. Injured patients with both home and incident zip codes were included. Outcomes included discordance and differential distance between home and incident zip code. Associations of discordance with patient characteristics were determined by logistic regression. We also assessed trauma center catchment areas based on home versus incident zip codes and variation regionally at each center. RESULTS: Fifty thousand one hundred seventy-five patients were included in the analysis. Home and incident zip codes were discordant in 21,635 patients (43.1%). Injuries related to motor vehicles (aOR: 4.76 [95% CI 4.50-5.04]) and younger adults 16-64 (aOR: 2.46 [95% CI 2.28-2.65]) were most likely to be discordant. Additionally, as injury severity score increased, discordance increased. Trauma center catchment area differed up to two-thirds of zip codes when using home versus incident location. Discordance rate, discordant distance, and catchment area overlap between home and incident zip codes all varied significantly by geographic region. CONCLUSIONS: Home location as proxy for injury location should be used with caution and may impact trauma system planning and policy, especially in certain populations. More accurate geolocation data are warranted to further optimize trauma system design.

OBJECTIVE: Pediatric patients comprise 13% of emergency medical services (EMS) transports, and most are transported to general emergency departments (ED). EMS transport destination policies may guide when to transport patients to a children's hospital, especially for medical complaints. Factors that influence EMS providers 'decisions about where to transport children are unknown. Our objective was to evaluate the factors associated with pediatric EMS transports to children's hospitals for medical complaints. METHODS: We performed a cross-sectional study of a large, urban EMS system over a 12-month period for all transports of patients 0-17 years old. We electronically queried the EMS database for demographic data, medical presentation and management, comorbidities, and documented reasons for choosing destination. Distances to the destination hospital and nearest children's and community hospital (if not the transport destination) were calculated. Univariate and multiple logistic regression analyses were conducted to determine the association between independent variables and the transport destination. RESULTS: We identified 10,065 patients, of which 6982 (69%) were for medical complaints. Of these medical complaints, 3518 (50.4%) were transported to a children's hospital ED. Factors associated with transport to a children's hospital include ALS transport, greater transport distance, protocol determination, developmental delay, or altered consciousness. Factors associated with transport to general EDs were older age, unknown insurance status, lower income, greater distance to children's or community hospital, destination determined by closest facility or diversion, abnormal respiratory rate or blood glucose, psychiatric primary impression, or communication barriers present. CONCLUSIONS: We found that younger patient age, EMS protocol requirements, and paramedic scene response may influence pediatric patient transport to both children's and community hospitals. Socioeconomic factors, ED proximity, diversion status, respiratory rate, chief complaints, and communication barriers may also be contributing factors. Further studies are needed to determine the generalizability of these findings to other EMS systems.

INTRODUCTION: Endotracheal intubation is an import component of out-of-hospital cardiac arrest (OHCA) resuscitation. In this analysis, we evaluate the association of video laryngoscopy (VL) with first pass success and return of spontaneous circulation (ROSC) using a national OHCA cohort. METHODS: We analyzed 2018 data from ESO Inc. (Austin, TX), a national prehospital electronic health record. We included all adult, non-traumatic cardiac arrests undergoing endotracheal intubation. We defined VL and direct laryngoscopy (DL) based on paramedic recorded intubation device. The primary outcomes were first pass success, ROSC, and sustained ROSC. Using multivariable, mixed models, we determined the association between VL and first pass success rate, ROSC, and sustained ROSC (survival to ED or ROSC in the field for greater than 20â¯min), fitting agency as a random intercept and adjusting for confounders. RESULTS: We included 22,132 patients cared for by 914 EMS agencies, including 5702 (25.7%) VL and 16,430 (74.2%) DL. Compared to DL, VL had a lower rate of bystander CPR, but other characteristics were similar between the groups. VL exhibited higher first pass success than DL (75.1% v 69.5%, pâ¯<â¯.001). On mixed model analysis, VL was associated with a higher first pass success (OR 1.5, CI 1.3-1.6) but not ROSC (OR 1.1, CI 0.97-1.2) or sustained ROSC (OR 1.1, CI 0.9-1.2). CONCLUSION: While associated with higher FPS, VL was not associated with increased rate of ROSC. The role of VL in OHCA remains unclear.

BACKGROUND: Seizures are a common reason why emergency medical services (EMS) transports children by ambulance. Timely seizure cessation prevents neurologic morbidity, respiratory compromise, and mortality. Implementing recommendations from an evidence-based pediatric prehospital guideline may enhance timeliness of seizure cessation and optimize medication dosing. OBJECTIVE: We compared management of pediatric prehospital seizures across several EMS systems after protocol revision consistent with an evidence-based guideline. METHODS: Using a retrospective, cross-sectional approach, we evaluated actively seizing patients (0-17 years old) EMS transported to a hospital before and after modifying local protocols to include evidence-based recommendations for seizure management in three EMS agencies. We electronically queried and manually abstracted both EMS and hospital data at each site to obtain information about patient demographics, medications given, seizure cessation and recurrence, airway interventions, access obtained, and timeliness of care. The primary outcome of the study was the appropriate administration of midazolam based on route and dose. We analyzed these secondary outcomes: frequency of seizure activity upon emergency department (ED) arrival, frequency of respiratory failure, and timeliness of care. RESULTS: We analyzed data for 533 actively seizing patients. Paramedics were more likely to administer at least one dose of midazolam after the protocol updates [127/208 (61%) vs. 232/325 (71%), p = 0.01, OR = 1.60 (95% CI: 1.10-2.30)]. Paramedics were also more likely to administer the first midazolam dose via the preferred intranasal (IN) or intramuscular (IM) routes after the protocol change [(63/208 (49%) vs. 179/325 (77%), p < 0.001, OR = 3.24 (2.01-5.21)]. Overall, paramedics administered midazolam approximately 14 min after their arrival, gave an incorrect weight-based dose to 130/359 (36%) patients, and gave a lower than recommended dose to 94/130 (72%) patients. Upon ED arrival, 152/533 (29%) patients had a recurrent or persistent seizure. Respiratory failure during EMS care or subsequently in the ED occurred in 90/533 (17%) patients. CONCLUSIONS: Implementation of an evidence-based seizure protocol for EMS increased midazolam administration. Patients frequently received an incorrect weight-based dose. Future research should focus on optimizing administration of the correct dose of midazolam to improve seizure cessation.

INTRODUCTION: Prehospital pediatric endotracheal intubation has lower first-pass success rates compared to adult intubations and in general may not offer a survival benefit. Increasingly, emergency medical services (EMS) systems are deploying prehospital extraglottic airways (EGA) for primary pediatric airway management, yet little is known about their efficacy. We evaluated the impact of a pediatric prehospital airway management protocol change, inclusive of EGAs, on airway management and patient outcomes in children in cardiac arrest or respiratory failure. METHODS: Using data from a large, metropolitan, fire-based EMS service, we performed an observational study of pediatric patients with respiratory failure or cardiac arrest who were transported by EMS before and after implementation of an evidence-based airway management protocol inclusive of the addition of the EGA. The primary outcome was change in frequency of intubation attempts when paired with an initial EGA. Secondary outcomes included EGA and intubation success rates and patient survival to hospitalization and discharge. RESULTS: We included 265 patients age <16 years old, with 142 pre- and 123 post-protocol change. Patient demographics and event characteristics were similar between groups. Intubation attempts declined from 79.6% pre- to 44.7% (p<0.01) post-protocol change. In patients with an intubation attempt, overall intubation success declined from 81.4% to 63.6% (p<0.01). Post-protocol change, an EGA was attempted in 52.8% of patients with 95.4% success. CONCLUSION: Implementation of an evidenced-based airway management algorithm for pediatric patients, inclusive of an EGA device for all age groups, was associated with fewer prehospital intubations. Intubation success may be negatively impacted due to decreases in procedural frequency.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) is associated with high mortality. Current methods for predicting mortality post-arrest require data unavailable at the time of initial medical contact. We created and validated a risk prediction model for patients experiencing OHCA who achieved return of spontaneous circulation (ROSC) which relies only on objective information routinely obtained at first medical contact. METHODS: We performed a retrospective evaluation of 14,892 OHCA patients in a large metropolitan cardiac arrest registry, of which 3952 patients had usable data. This population was divided into a derivation cohort (n = 2,635) and a verification cohort (n = 1,317) in a 2:1 ratio. Backward stepwise logistic regression was used to identify baseline factors independently associated with death after sustained ROSC in the derivation cohort. The cardiac arrest survival score (CASS) was created from the model and its association with in-hospital mortality was examined in both the derivation and verification cohorts. RESULTS: Baseline characteristics of the derivation and verification cohorts were not different. The final CASS model included age >75 years (odds ratio [OR] = 1.61, confidence interval [CI][1.30-1.99], p < 0.001), unwitnessed arrest (OR = 1.95, CI[1.58-2.40], p < 0.001), home arrest (OR = 1.28, CI[1.07-1.53], p = 0.008), absence of bystander CPR (OR = 1.35, CI[1.12-1.64], p = 0.003), and non-shockable initial rhythm (OR = 3.81, CI[3.19-4.56], p < 0.001). The area under the curve for the model derivation and model verification cohorts were 0.7172 and 0.7081, respectively. CONCLUSION: CASS accurately predicts mortality in OHCA patients. The model uses only binary, objective clinical data routinely obtained at first medical contact. Early risk stratification may allow identification of more patients in whom timely and aggressive invasive management may improve outcomes.

Background: Seizures have the potential to cause significant morbidity and mortality, and are a common reason emergency medical services (EMS) are requested for a child. An evidence-based guideline (EBG) for pediatric prehospital seizures was published and has been implemented as protocol in multiple EMS systems. Knowledge translation and protocol adherence in medicine can be incomplete. In EMS, systems-based factors and providers' attitudes and beliefs may contribute to incomplete knowledge translation and protocol implementation. Objective: The purpose of this study was to identify paramedic attitudes and beliefs regarding pediatric seizure management and regarding potential barriers to and enablers of adherence to evidence-based pediatric seizure protocols in multiple EMS systems. Methods: This was a qualitative study utilizing semi-structured interviews of paramedics who recently transported actively seizing 0-17 year-old patients in 3 different urban EMS systems. Interviewers explored the providers' decision-making during their recent case and regarding seizures in general. Interview questions explored barriers to and enablers of protocol adherence. Two investigators used the grounded theory approach and constant comparison to independently analyze transcribed interview recordings until thematic saturation was reached. Findings were validated with follow-up member-checking interviews. Results: Several themes emerged from the 66 interviewed paramedics. Enablers of protocol adherence included point-of-care references, the availability of different routes for midazolam and availability of online medical control. Systems-level barriers included equipment availability, controlled substance management, infrequent pediatric training, and protocol ambiguity. Provider-level barriers included concerns about respiratory depression, provider fatigue, preferences for specific routes, febrile seizure perceptions, and inaccurate methods of weight estimation. Paramedics suggested system improvements to address dose standardization, protocol clarity, simplified controlled substance logistics, and equipment availability. Conclusions: Paramedics identified enablers of and barriers to adherence to evidence-based pediatric seizure protocols. The identified barriers existed at both the provider and systems levels. Paramedics identified multiple potential solutions to overcome several barriers to protocol adherence. Future research should focus on using the findings of this study to revise seizure protocols and to deploy measures to improve protocol implementation. Future research should also analyze process and outcome measures before and after the implementation of revised seizure protocols informed by the findings of this study.

Objective: Dual sequential defibrillation (DSD) - successive defibrillations with two defibrillators - offers a novel approach to refractory ventricular fibrillation (RVF) and tachycardia (VF/VT). While associated with rescue shock success, the effect of DSD upon out-of-hospital cardiac arrest (OHCA) is unknown. We evaluated the association of DSD with survival after refractory VF/VT OHCA. Methods: We used data from a large metropolitan fire-based EMS service. We included all adult OHCA during 2013-2016 with ≥3 standard defibrillations. Physicians authorized subsequent DSD use by two separate defibrillators (PhysioControl LIFEPAK® 12/15) with pads placed anterior-lateral and anterior-posterior. Evaluated outcomes included return of spontaneous circulation (ROSC), survival to hospital admission, survival to 72 hours, and survival to hospital discharge. Using multivariable logistic regression, we evaluated the association between defibrillation type and OHCA outcomes, adjusting for patient demographics and event characteristics. Results: We included 310 patients in the analysis, 71 patients receiving DSD and 239 receiving conventional defibrillation. Patient demographics and event characteristics were similar between both groups. ROSC was lower for DSD than standard defibrillation: 39.4% vs. 60.3%, adjusted OR 0.46 (95% CI: 0.25-0.87). There were no differences in survival to hospital admission (35.2% vs. 49.2%, adjusted OR 0.57 [95% CI: 0.30-1.08]), survival to 72 hours (21.4% vs. 32.3%, adjusted OR 0.52 [95% CI: 0.26-1.10]), or survival to hospital discharge (14.3% vs. 20.9%, adjusted OR 0.63 [95% CI: 0.27-1.45]). Conclusions: Compared with conventional defibrillation, DSD was associated with lower odds of prehospital ROSC. Defibrillation type was not associated with other OHCA endpoints. DSD may not be beneficial in refractory VF/VT OHCA.

BACKGROUND: Although all emergency departments (EDs) should be ready to treat children, some may have illnesses or injuries that require higher-level pediatric resources that are not available at all hospitals. There are no national guidelines for emergency medical services (EMS) providers about when to directly transport children to hospitals with higher-level pediatric resources, with the exception of severe trauma. Variability exists in EMS protocols about when children warrant transport to hospitals with higher-level pediatric care. OBJECTIVE: The objective was to determine how frequently pediatric patients are transported by EMS to hospitals with higher-level pediatric resources and to evaluate distribution patterns based on illness and injury severity. METHODS: We conducted a retrospective analysis of all pediatric (age 0-18 years) transports in three large EMS systems between November 2014 and November 2016. Each community had a hospital with higher-level pediatric resources that was within a 30-minute transport time from any location. Patients were included if they were transported by ground ambulance and the request originated in the 9-1-1 system. We assessed the frequency of transports to a hospital with higher-level pediatric resources. Data were stratified by chief complaint of illness or injury and severity. Potential risk for severe injury was defined as meeting the physiologic step of the field triage guidelines and potential risk for severe illness was defined as having an abnormal vital sign after adjusting for patient age. RESULTS: A total of 41,345 pediatric patients were transported by a participating EMS agency to an ED and had complete destination data. A total of 55% of all EMS-transported pediatric patients were transported to a hospital with higher-level pediatric resources. There was variation by site (range = 45%-71%) in the percentage of children who went to a hospital with higher-level pediatric resources. Patients over 15 years of age went to general EDs (57%) more often than younger patients. When stratified by severity, 60% of those with potentially severe illness and 74% of those with potentially severe trauma were transported to a hospital with higher-level pediatric resources. CONCLUSIONS: EMS providers commonly transport children to hospitals with higher-level pediatric resources. However, more than one-quarter of children with potentially severe injuries and illnesses are transported to general EDs.

Objective: Mobile stroke units offer improved time to administration of thrombolytics for ischemic stroke patients. Acquisition of intravenous (IV) access, however, can be challenging in the prehospital environment leading to treatment delays. Intraosseous (IO) access is commonly used in the prehospital setting for a variety of conditions and may serve as a viable means for tPA (tissue plasminogen activator) administration. Methods/Results: We describe 3 cases in which tPA was administered via IO access on a mobile stroke unit as part of the Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services (BEST-MSU) trial. Conclusion: No adverse events were observed in the process of obtaining IO access or administering tPA.

BACKGROUND: Seizures and anaphylaxis are life-threatening conditions that require immediate treatment in the prehospital setting. There is variation in treatment of pediatric prehospital patients for both anaphylaxis and seizures. This educational study was done to improve compliance with pediatric prehospital protocols, educate prehospital providers and decrease variation in care. OBJECTIVE: To improve the quality of care for children with seizures and anaphylaxis in the prehospital setting using a bundled, multifaceted educational intervention. METHODS: Evidence-based pediatric prehospital guidelines for seizures and anaphylaxis were used to create a curriculum for the paramedics in the EMS system. The curriculum included in-person training, videos, distribution of decision support tools, and a targeted social media campaign to reinforce the evidence-based guidelines. Prehospital charts were reviewed for pediatric patients with a chief complaint of anaphylaxis or seizures who were transported by paramedics to one of ten hospitals, including three children's hospitals, for 8 months prior to the intervention and eight months following the intervention. The primary outcome for seizures was whether midazolam was given via the preferred intranasal (IN) or intramuscular (IM) routes. The primary outcome for anaphylaxis was whether IM epinephrine was given. RESULTS: A total of 1,402 pediatric patients were transported for seizures by paramedics to during the study period. A total of 88 patients were actively seizing pre-intervention and 93 post-intervention. Of the actively seizing patients, 52 were given midazolam pre-intervention and 62 were given midazolam post-intervention. Pre-intervention, 29% (15/52) of the seizing patients received midazolam via the preferred IM or IN routes, compared to 74% (46/62) of the seizing patients post-intervention. A total of 45 patients with anaphylaxis were transported by paramedics, 30 pre-intervention and 15 post-intervention. Paramedics administered epinephrine to 17% (5/30) patients pre-intervention and 67% (10/15) patients post-intervention. CONCLUSION: The use of a bundled, multifaceted educational intervention including in-person training, decision support tools, and social media improved adherence to updated evidence-based pediatric prehospital protocols.

BACKGROUND: Respiratory distress due to asthma is a common reason for pediatric emergency medical services (EMS) transports. Timely initiation of asthma treatment, including glucocorticoids, improves hospital outcomes. The impact of EMS-administered glucocorticoids on hospital-based outcomes for pediatric asthma patients is unknown. OBJECTIVE: The objective of this study was to evaluate the effect of an evidence-based pediatric EMS asthma protocol update, inclusive of oral glucocorticoid administration, on time to hospital discharge. METHODS: This was a retrospective cohort study of children (2-18 years) with an acute asthma exacerbation transported by an urban EMS system to 10 emergency departments over 2 years. The investigators implemented an EMS protocol update one year into the study period requiring glucocorticoid administration for all patients, with the major change being inclusion of oral dexamethasone (0.6 mg/kg, max. dose = 10 mg). Protocol implementation included mandatory paramedic training. Data was abstracted from linked prehospital and hospital records. Continuous data were compared before and after the protocol change with the Mann-Whitney test, and categorical data were compared with the Pearson χ2 test. RESULTS: During the study period, 482 asthmatic children met inclusion criteria. After the protocol change, patients were more likely to receive a prehospital glucocorticoid (11% vs. 18%, p = 0.02). Median total hospital time after the protocol change decreased from 6.1 hours (95% CI: 5.4-6.8) to 4.5 hours (95% CI: 4.2-4.8), p < 0.001. Total care time, defined as time from ambulance arrival to hospital discharge, also decreased [6.6 hours (95% CI: 5.8-7.3) vs. 5.2 hours (95% CI: 4.8-5.6), p = 0.01]. Overall, patients were less likely to be admitted to the hospital (30% vs. 21%, p = 0.02) after the change. Those with more severe exacerbations were less likely to be admitted to a critical care unit (82% vs. 44%, p = 0.02) after the change, rather than an acute care floor. CONCLUSIONS: Prehospital protocol change for asthmatic children is associated with shorter total hospital and total care times. This protocol change was also associated with decreased hospitalization rates and less need for critical care in those hospitalized. Further study is necessary to determine if other factors also contributed.

INTRODUCTION: This comprehensive review synthesizes the existing literature on the Patient Protection and Affordable Care Act (ACA) as it relates to emergency medical services (EMS) in order to provide guidance for navigating current and future healthcare changes. METHODS: We conducted a comprehensive review to identify all existing literature related to the ACA and EMS and all sections within the federal law pertaining to EMS. RESULTS: Many changes enacted by the ACA directly affect emergency care with potential indirect effects on EMS systems. New Medicaid enrollees and changes to existing coverage plans may alter EMS transport volumes. Reimbursement changes such as adjustments to the ambulance inflation factor (AIF) alter the yearly increases in EMS reimbursement by incorporating the multifactor productivity value into yearly reimbursement adjustments. New initiatives, funded by the Center for Medicare & Medicaid Innovation are exploring novel and cost-effective prehospital care delivery opportunities while EMS agencies individually explore partnerships with healthcare systems. CONCLUSION: EMS systems should be aware of the direct and indirect impact of ACA on prehospital care due to the potential for changes in financial reimbursement, acuity and volume changes, and ongoing new care delivery initiatives.

OBJECTIVE: Many Emergency Medicine Services (EMS) protocols require point-of-care blood glucose testing (BGT) for any pediatric patient who presents with seizure or altered level of conscious. Few data describe the diagnostic yield of BGT when performed on all pediatric seizures regardless of presenting mental status. We analyzed a large single center dataset of pediatric patients presenting with prehospital seizures to determine the prevalence of hypoglycemic seizures and the utility of repeat BGT in the emergency department (ED). METHODS: This was a retrospective, IRB-approved chart analysis of all pediatric patients (≤14 years) transported by EMS to the Harbor-UCLA pediatric ED over a 2-year period with a chief complaint of seizure. Cases were selected in which witnessed seizures had occurred in the field by family or EMS. Chart review included prehospital, nursing and physician records. Hypoglycemia was defined as blood glucose <60 mg/dL. Analysis included blood glucose, witnessed field seizure, initial mental status assessed by Glasgow Coma Scale (GCS), and further mental status assessments, along with age, sex, and medical history. Medical records were reviewed for subsequent BGT and patient outcome. RESULTS: A total 770 children were transported by EMS due to seizures. Four patients (0.5%) had recorded hypoglycemia in the field, yet only two received treatment to raise blood glucose. Additionally, one child (0.1%) was normoglycemic (81 mg/dL) in the field with hypoglycemia (43 mg/dL) in the ED but required no intervention. Two were found by EMS to have an ALOC (GCS ≤ 12) and hypoglycemia. Only the patient with hypoglycemia secondary to a suspected glipizide ingestion received ED glucose administration. The most common discharge diagnosis was simple febrile seizure (38.6%). CONCLUSION: Hypoglycemia in the pediatric seizure patient is extremely rare, thus universal field BGT has low utility and potential downstream effects. We propose a novel algorithm for the initial evaluation and management of prehospital pediatric seizures. Although limited to a retrospective analysis of a single medical center, our findings suggest the importance of reassessing prehospital seizure protocols. A larger patient sample should be studied to validate these findings and identify unique cases where glucose testing might be useful.

BACKGROUND: The National Association of Emergency Medical Services Physicians' (NAEMSP) Position Statement on Prehospital Pain Management and the joint National Highway Traffic Safety Administration (NHTSA) and Emergency Medical Services for Children (EMSC) Evidence-based Guideline for Prehospital Analgesia in Trauma aim to improve the recognition, assessment, and treatment of prehospital pain. The impact of implementation of these guidelines on pain management in children by emergency medical services (EMS) agencies has not been assessed. OBJECTIVE: Determine the change in frequency of documented pain severity assessment and opiate administration among injured pediatric patients in three EMS agencies after adoption of best practice recommendations. METHODS: This is a retrospective study of children <18 years of age with a prehospital injury-related primary impression from three EMS agencies. Each agency independently implemented pain protocol changes which included adding the use of age-appropriate pain scales, decreasing the minimum age for opiate administration, and updating fentanyl dosing. We abstracted data from prehospital electronic patient records before and after changes to the pain management protocols. The primary outcomes were the frequency of administration of opioid analgesia and documentation of pain severity assessment as recorded in the prehospital patient care record. RESULTS: A total of 3,597 injured children were transported prior to pain protocol changes and 3,743 children after changes. Opiate administration to eligible patients across study sites regardless of documentation of pain severity was 156/3,089 (5%) before protocol changes and 175/3,509 (5%) after (p = 0.97). Prior to protocol changes, 580 (18%) children had documented pain assessments and 430 (74%) had moderate-to-severe pain. After protocol changes, 644 (18%) patients had pain severity documented with 464 (72%) in moderate-to-severe pain. For all study agencies, pain severity was documented in 13%, 19%, and 22% of patient records both before and after protocol changes. There was a difference in intranasal fentanyl administration rates before (27%) and after (17%) protocol changes (p = 0.02). CONCLUSION: The proportion of injured children who receive prehospital opioid analgesia remains suboptimal despite implementation of best practice recommendations. Frequency of pain severity assessment of injured children is low. Intranasal fentanyl administration may be an underutilized modality of prehospital opiate administration.

OBJECTIVE: To describe the creation and evaluate the usage of the first medical wiki linked to dedicated mobile applications. METHODS: With the support of multiple current and past contributors, we developed an emergency medicine wiki linked to offline mobile applications (WikEM) in 2009. First deployment was at the Harbor-UCLA Medical Center emergency medicine residency program, with the wiki later opened to public use. To evaluate the project, we performed a post hoc analysis of system use and surveyed 8 years of current and past residents. Outcomes included website and application analytics, as well as survey analysis by composite response categories. RESULTS: Over the 6-year period of this project, the wiki grew to over 7250 pages and 45 500 edits. The website receives more than 85 000 user sessions per month, with over 150 million page views to date. There have been over 200 000 installs of the mobile applications, progressing to produce over 5000 mobile sessions daily. Of potential survey respondents, 87.7% (107) completed the Internet-based survey. Among those who contributed to the wiki, 74.6% reported that it benefited their understanding of core emergency medicine content. Of program graduates, the vast majority reported use of the wiki as a resource after residency (93.8%) along with improvement in clinical efficiency (89.7%). Residents reported higher use and a more favorable opinion of wiki usefulness compared to graduates (P < .001). CONCLUSIONS: A wiki paired with mobile applications is beneficial for resident education and useful in post-residency clinical practice.

BACKGROUND: Pediatric prehospital research has been limited, but work in this area is starting to increase particularly with the growth of pediatric-specific research endeavors. Given the increased interest in pediatric prehospital research, there is a need to identify specific research priorities that incorporate the perspective of prehospital providers and other emergency medical services (EMS) stakeholders. OBJECTIVES: To develop a list of specific research priorities that is relevant, specific, and important to the practice of pediatric prehospital care. METHODS: Three independent committees of EMS providers and researchers were recruited. Each committee developed a list of research topics. These topics were collated and used to initiate a modified Delphi process for developing consensus on a list of research priorities. Participants were the committee members. Topics approved by 80% were retained as research priorities. Topics that were rejected by more than 50% were eliminated. The remaining topics were modified and included on subsequent surveys. Each survey allowed respondents to add additional topics. The surveys were continued until all topics were either successfully retained or rejected and no new topics were suggested. RESULTS: Fifty topics were identified by the three independent committees. These topics were included on the initial electronic survey. There were 5 subsequent surveys. At the completion of the final survey a total of 29 research priorities were identified. These research priorities covered the following study areas: airway management, asthma, cardiac arrest, pain, patient-family interaction, resource utilization, seizure, sepsis, spinal immobilization, toxicology, trauma, training and competency, and vascular access. The research priorities were very specific. For example, under airway the priorities were: "identify the optimal device for effectively managing the airway in the prehospital setting" and "identify the optimal airway management device for specific disease processes." CONCLUSION: This project developed a list of relevant, specific, and important research priorities for pediatric prehospital care. Some similarities exist between this project and prior research agendas but this list represents a current, more specific research agenda and reflects the opinions of working EMS providers, researchers, and leaders.
