In adult protease inhibitor (PI)-experienced patients, a lopinavir (LPV) phenotypic inhibitory quotient (PIQ) of >15 has been associated with a higher likelihood of viral suppression. The aims of this study were to develop a population pharmacokinetic (PK) model of LPV in children and to estimate the probability of achieving a PIQ of >15. HIV-infected, PI-experienced children receiving LPV were intensively sampled for 12 h to measure plasma LPV. The data were fitted to candidate PK models (using MM-USCPACK software), and the final model was used to simulate 1,000 children to determine the probability of achieving an LPV PIQ of >15. In 50 patients (4 to 18 years old), the median LPV plasma 12-hour-postdose concentration was 5.9 mg/liter (range, 0.03 to 16.2 mg/liter) lower than that reported in adults. After a delay, LPV was absorbed linearly into a central compartment whose size was dependent on the weight and age of the patient. Elimination was dependent on weight. The regression line of observed versus predicted LPV had an R 2 of 0.99 and a slope of 1.0. Visual predictive checks against all available measured concentrations showed good predictive ability of the model. The probability of achieving an LPV PIQ of >15 was >90% for wild-type virus but <10% for even moderately resistant virus. The currently recommended dose of LPV/ritonavir appears to be adequate for children infected with wild-type virus but is unlikely to provide adequate inhibitory concentrations for even moderately resistant human immunodeficiency virus (HIV). PI-experienced HIV-infected children will likely benefit from longitudinal, repeated LPV measurement in plasma to ensure that drug exposure is most often near the maximal end of the observed safe range.Lopinavir/ritonavir (LPV/RTV) (Kaletra) is the first and only coformulated RTV-boosted protease inhibitor (PI) approved for use in children. The recommended doses for children who weigh more than 15 kg are 10 mg/kg of body weight or 230 mg/m 2 (body surface area) twice daily, with a maximum of 400 mg per dose unless it is combined with drugs affecting cytochrome (CYP) P450 metabolism, which require LPV dose adjustment (4, 28). Introduced as a salvage agent (22), LPV/RTV has become one of the preferred PI choices for first-line regimens in children Ͼ6 months of age in the countries with access to the drug.Despite evidence for good antiviral efficacy among children in a clinical trial setting (16,17,23), the standard dose may not be adequate for every child. Noncompartmental analysis has shown that the average LPV plasma 12-hour-postdose concentration (C trough ) in children given the currently recommended pediatric dose of LPV is 67% lower than in adults (24). Recently, Jullien et al. published a population pharmacokinetics (PK) model of LPV in children aged 0 to 18 years (15). The model was based on a retrospective analysis of LPV plasma measurements in 157 children, with a median of 3 samples (range, 1 to 14) per patient, obtained for monitoring purposes after self-reported LPV intake.

Background: Understanding gender gaps in trainee evaluations is critical because these may ultimately determine the duration of training. Currently, no studies describe the influence of gender on the evaluation of pediatric emergency medicine (PEM) fellows. Objective:The objective of our study was to compare milestone scores of female versus male PEM fellows. Methods: This is a multicenter retrospective cohort study of a national sample of PEM fellows from July 2014 to June 2018. Accreditation Council for Medical Education (ACGME) subcompetencies are scored on a 5-point scale and span six domains: patient care (PC), medical knowledge, systems-based practice, practice-based learning and improvement, professionalism, and interpersonal and communication skills (ICS). Summative assessments of the 23 PEM subcompetencies are assigned by each program's clinical competency committee and submitted semiannually for each fellow. Program directors voluntarily provided deidentified ACGME milestone reports. Demographics including sex, program region, and type of residency were collected. Descriptive analysis of milestones was performed for each year of fellowship. Multivariate analyses evaluated the difference in scores by sex for each of the subcompetencies.Results: Forty-eight geographically diverse programs participated, yielding data for 639 fellows (66% of all PEM fellows nationally); sex was recorded for 604 fellows, of whom 67% were female. When comparing the mean milestone scores in each of the six domains, there were no differences by sex in any year of training. When comparing scores within each of the 23 subcompetencies and correcting the significance level for comparison of multiple milestones, the scores for PC3 and ICS2 were significantly, albeit not meaningfully, higher for females.

BackgroundOut-of-hospital emergency care is at an early stage of development in Armenia, with the current emergency medical services (EMS) system having emergency physicians (EPs) work on ambulances along with nurses. While efforts are underway by the Ministry of Health and other organizations to reform the EMS system, little data exists on the status of pediatric emergency care (PEC) in the country. We designed this study to evaluate the knowledge and attitudes of out-of-hospital emergency physicians in pediatric rapid assessment and resuscitation, and identify areas for PEC improvement.MethodsWe distributed an anonymous, self-administered Knowledge and Attitudes survey to a convenience sample of out-of-hospital EPs in the capital, Yerevan, from August to September 2012.ResultsWith a response rate of 80%, the majority (89.7%) of respondents failed a 10-question knowledge test (with a pre-defined passing score of ≥7) with a mean score of 4.17 ± 1.99 SD. Answers regarding the relationship between pediatric cardiac arrest and respiratory issues, compression-to-ventilation ratio in neonates, definition of hypotension, and recognition of shock were most frequently incorrect. None of the participants had attended pediatric-specific continuing medical education (CME) activities within the preceding 5 years. χ2 analysis demonstrated no statistically significant association between physician age, length of EMS experience, type of ambulance (general vs. resuscitation/critical care), or CME attendance and pass/fail status. The majority of participants agreed that PEC education in Armenia needs improvement (98%), that there is a need for pediatric-specific CME (98%), and that national out-of-hospital PEC guidelines would increase PEC safety, efficiency, and effectiveness (96%).ConclusionsOut-of-hospital emergency physicians in Yerevan, Armenia are deficient in pediatric-specific emergency assessment and resuscitation knowledge and training, but express a clear desire for improvement. There is a need to support additional PEC training and CME within the EMS system in Armenia.

Torticollis is a common complaint in the pediatric emergency department. Here, we report what we believe to be the first example in a young child of a fracture of the anterior arch of the atlas associated with an acquired, postsurgical defect of the posterior arch. A brief review of pediatric cervical spine injuries and fractures is presented. Atlas laminectomy may predispose patients to isolated atlas fractures even with minor trauma. Those fractures, however, are stable and treated by hard cervical orthosis.

Background: Pediatric emergency medicine (PEM) fellowships accept trainees who have completed a residency in either emergency medicine (EM) or pediatrics and have adopted 17 subcompetencies with accompanying set of milestones from these two residency programs. This study aims to examine the changes in milestone scores among common subcompetencies from the end of EM or pediatrics residency to early PEM fellowship and evaluates time to reattainment of scores for subcompetencies in which a decline was noted. Methods: This is a national, retrospective cohort study of trainees enrolled in PEM fellowship programs from July 2014 to June 2018. PEM fellowship program directors voluntarily submitted deidentified milestone reports within the study time frame, including end-of-residency reports. Descriptive analyses of milestone scores between end of residency and PEM fellowship were performed. Results: Forty-eight U.S. PEM fellowship programs (65%) provided fellowship milestone data on 638 fellows, 218 (34%) of whom also had end-of-residency milestone scores submitted. Of 218 fellows eligible for analysis, 210 (96%) had completed a pediatrics residency and eight (4%) had completed an EM residency. Pediatric-trained fellows had statistically significant decreases in mean milestone scores in all 10 shared subcompetencies. Reattainment of milestone scores across all common subcompetencies for both EM and pediatric-trained PEM fellows occurred by the end of fellowship. Conclusions: This study demonstrated declines in milestone scores from the end of primary residency training in pediatrics to early PEM fellowship in shared subcompetencies, which may suggest that performance expectations are reset at the beginning of PEM fellowship. Changes in subcompetency milestone anchors to provide subspecialty-specific context may be needed to more accurately define skills acquisition in the residency-to-fellowship transition.

Objectives: Entrustable Professional Activities (EPAs) are essential tasks physicians perform within their professions. Entrustment levels that pediatric emergency medicine (PEM) fellowship program directors (FPDs) expect graduating fellows to achieve for PEM-specific and common pediatric subspecialty EPAs remain unreported. This study aims to determine minimum entrustment levels FPDs require fellows to achieve to graduate from fellowship and to compare FPD expectations for fellows versus practicing PEM physicians.Methods: Secondary analysis of PEM-specific data from a national multispecialty cross-sectional survey of pediatric subspecialty FPDs. For 6 PEM-specific and 7 common pediatric subspecialty EPAs, PEM FPDs indicated (1) minimum entrustment levels fellows should achieve by training completion, (2) whether they would allow a fellow to graduate below these minimum levels, and (3) minimum levels for safe and effective practice by PEM physicians. Minimum levels were defined as the level that more than 80% of FPDs would not drop below.Results: Sixty of 77 PEM FPDs (78%) completed the survey. Most respondents did not require fellows to achieve the highest level (level 5-no supervision) by graduation for any PEM-specific EPAs. The median level FPDs expected for practicing PEM physicians was 5 (trusted to perform without supervision) for EPAs 1 and 4 and level 4 (indirect supervision for complex cases) for the remaining PEM-specific EPAs. Minimum levels expected by FPDs for common subspecialty pediatric EPAs were lower for both groups.Conclusions: Most PEM FPDs indicated that they would graduate fellows before their achievement of the highest entrustment level for all EPAs. Most also indicated that they do not expect practicing PEM physicians to perform all EPAs without supervision. These findings indicate need for stakeholders to evaluate current structure and outcomes of PEM fellowship programs and for institutions and organizations to ensure adequate support in time and resources for ongoing learning for practicing PEM physicians.

Background: Pediatric emergency medicine (PEM) fellowships recruit trainees from both pediatric and emergency medicine (EM) residencies. The Accreditation Council for Graduate Medical Education (ACGME) defines separate training pathways for each. The 2015 PEM milestones reflect a combination of subcompetencies from the two residencies. This project aims to compare the milestone achievement of PEM fellows based on their primary residency training. We hypothesize that fellows trained in pediatrics achieve PEM milestones at different rates than EM-trained fellows in the ACGME domains of patient care, medical knowledge, systems-based practice, practice-based learning, professionalism, and interpersonal and communication skills. Methods: This is a multicenter, retrospective cohort study of fellows from a national sample of U.S. PEM fellowship programs. Basic demographic information and deidentified, biannual milestone scores for 23 competencies were collected for fellows training between 2015 and 2018. Subcompetencies are scored on a 5-point milestone scale. Descriptive and multivariable analyses for longitudinal data were performed to compare milestone assessments by primary residency training.Results: Complete data were obtained for 600 fellows; 95% (570) and 5% (30) completed pediatric and EM residency, respectively. In both year 1 and year 2 of fellowship, the mean milestone scores of EM-trained fellows were statistically higher than pediatrics-trained fellows across the majority of subcompetencies. By the final year of training, there were no statistically significant differences in milestone scores for any of the subcompetencies.Conclusions: Fellow milestone achievement between groups was not significantly different by graduation. However, fellows entering PEM training from an EM background attained higher scores on the milestones than fellows from a pediatric background in the first year of fellowship.

Background Emergency pediatric care curriculum (EPCC) was developed to address the need for pediatric rapid assessment and resuscitation skills among out-of-hospital emergency providers in Armenia. This study was designed to evaluate the effectiveness of EPCC in increasing physicians’ knowledge when instruction transitioned to local instructors. We hypothesize that (1) EPCC will have a positive impact on post-test knowledge, (2) this effect will be maintained when local trainers teach the course, and (3) curriculum will satisfy participants. Methods This is a quasi-experimental, pre-test/post-test study over a 4-year period from October 2014‑November 2017. Train-the-trainer model was used. Primary outcomes are immediate knowledge acquisition each year and comparison of knowledge acquisition between two cohorts based on North American vs local instructors. Descriptive statistics was used to summarize results. Pre-post change and differences across years were analyzed using repeated measures mixed models. Results Test scores improved from pretest mean of 51% (95% CI 49.6 to 53.0%) to post-test mean of 78% (95% CI 77.0 to 79.6%, p < 0.001). Average increase from pre- to post-test each year was 27% (95% CI 25.3 to 28.7%). Improvement was sustained when local instructors taught the course (p = 0.74). There was no difference in improvement when experience in critical care, EMS, and other specialties were compared (p = 0.23). Participants reported satisfaction and wanted the course repeated. In 2017, EPCC was integrated within the Emergency Medicine residency program in Armenia. Discussion This program was effective at impacting immediate knowledge as well as participant satisfaction and intentions to change practice. This knowledge acquisition and reported satisfaction remained constant even when the instruction was transitioned to the local instructors after 2 years. Through a partnership between the USA and Armenia, we provided OH-EPs in Armenia with an intensive educational experience to attain knowledge and skills necessary to manage acutely ill or injured children in the out-of-hospital setting. Conclusions EPCC resulted in significant improvement in knowledge and was well received by participants. This is a viable and sustainable model to train providers who have otherwise not had formal education in this field.
