Pediatric Facial Fractures: Demographics, Injury Patterns, and Associated Injuries in 3334 Patients.

Pediatric craniofacial fractures are fundamentally distinct from their adult counterparts because of unique injury patterns and effects on future growth. Understanding patterns and injury context informs management and risk mitigation. Previous studies include only inpatients, operative patients, or are specialty-specific. In contrast, our study presents a comprehensive assessment of all pediatric facial fracture patients seen at a single institution. Patients under 18 years old who were evaluated for facial fractures at a level I pediatric trauma center between 2006 and 2021 were reviewed. Subanalysis was performed for groups defined by age. Variables studied included demographics, etiology, fracture pattern, associated injuries, management, and outcomes. Three thousand thirty-four patients were included. Mean age at presentation was 11.5 to 4.9 years. The majority were Caucasian (82.6%) and male (68.4%). Sports were the leading cause of injury in older patients (42.2% of patients over 12 y), compared with activities of daily living in patients under 6 years (45.5%). Thirty-two percent of patients were hospitalized, 6.0% required ICU care, and 48.4% required surgery. Frequency of ICU admission decreased with age (P<0.001), whereas operative intervention increased with age (P<0.001). Zygomaticomaxillary complex (P=0.002) and nasal fractures (P<0.001) were common in older patients, whereas younger patients experienced more skull (P<0.001) and orbital fractures (P<0.001). The most associated injuries were soft tissue (55.7%) and neurologic (23.6%). This large-scale study provides updated characterization of craniofacial fractures in the pediatric population, providing a necessary framework for future studies on outcomes assessments and preventative care.

Pediatric Nasoorbitoethmoid Fractures: A Single Institution's 15-Year Experience.

BACKGROUND: Nasoorbitoethmoid (NOE) fractures impact growth of the craniofacial skeleton in children, which may necessitate differentiated management from adult injuries. This study describes characteristics, management, and outcomes of NOE fractures in children seen at a single institution. METHODS: A retrospective review of patients under 18 years who presented to our institution from 2006 to 2021 with facial fractures was conducted; patients with NOE fractures were included. Data collected included demographics, mechanism of injury, fracture type, management, and outcomes. RESULTS: Fifty-eight patients met inclusion criteria; 77.6% presented with Manson-Marcowitz Type I fractures, 17.2% with Type II, and 5.2% with Type III. The most common cause of injury was motor vehicle accidents (MVAs, 39.7%) and sports (31%). Glasgow Coma Scale and injury mechanism were not predictive of injury severity in the pediatric population ( P =0.353, P =0.493). Orbital fractures were the most common associated fractures (n=55, 94.8%); parietal bone fractures were more likely in Type III fractures ( P =0.047). LeFort III fractures were more likely in type II fractures ( P =0.011). Soft tissue and neurological injuries were the most common associated injuries regardless of NOE fracture type (81% and 58.6%, respectively). There was no significant difference in type of operative management or in the rates of adverse outcomes between types of NOE fractures. CONCLUSIONS: These findings suggest that pediatric NOE fractures, although rare, present differently from adult NOE fractures and that revisiting predictive heuristics and treatment strategies is warranted in this population.

Increased Fellow Scholarly Publication Rate After Implementation of a Comprehensive Research Curriculum and Milestone-Based Research Timeline for Pediatric Emergency Medicine Fellows.

OBJECTIVE: Pediatric subspecialty fellows are required to complete a scholarly product during training; however, many do not bring the work to publication. To amplify our fellows' publication success, our pediatric emergency medicine fellowship program implemented a comprehensive research curriculum and established a milestone-based research timeline for each component of a project. Our objective was to assess whether these interventions increased the publication rate and enhanced the graduated fellows' perceived ability to perform independent research. METHODS: Our study was conducted at a tertiary children's hospital affiliated with an academic university, enrolling 3 fellows each year in its pediatric emergency medicine program. A comprehensive research curriculum and a milestone-based research timeline were implemented in 2011. We analyzed the publication rate of our graduating fellows before (2004-2011) and after (2012-2016) our intervention. In addition, in 2017 we surveyed our previous fellows who graduated from 2004 to 2016 and analyzed factors favoring manuscript publication and confidence with various research skills. RESULTS: During the study period, 38 trainees completed the fellowship program. Publication rate increased from 26% ± 17% to 87% ± 30 % ( P < 0.05). When scoring the importance of various factors, fellows most valued mentorship (5 ± 0 vs 4.3 ± 1.0, P < 0.05, postintervention vs preintervention) for the completion of the fellowship study and manuscript. Fellows after the intervention reported greater confidence in performing an analysis of variance (89% vs 36%, odds ratio, 6.3; 95% confidence interval, 1.4-150.1). CONCLUSIONS: Implementation of a comprehensive research curriculum and a milestone-based research timeline was associated with an increase in the publication rate within 3 years of graduation of our pediatric emergency medicine fellows. After implementation, fellows reported an increased importance of mentorship and greater confidence in performing an analysis of variance. We provide a comprehensive curriculum and a research timeline that may serve as a model for other fellowship programs.

Emergency management of fever and neutropenia in children with cancer: A review.

INTRODUCTION: Care of pediatric cancer patients is increasingly being provided by physicians in community settings, including general emergency departments. Guidelines based on current evidence have standardized the care of children undergoing chemotherapy or hematopoietic stem cell transplantation (HSCT) presenting with fever and neutropenia (FN). OBJECTIVE: This narrative review evaluates the management of pediatric patients with cancer and neutropenic fever and provides comparison with the care of the adult with neutropenic fever in the emergency department. DISCUSSION: When children with cancer and FN first present for care, stratification of risk is based on a thorough history and physical examination, baseline laboratory and radiologic studies and the clinical condition of the patient, much like that for the adult patient. Prompt evaluation and initiation of intravenous broad-spectrum antibiotics after cultures are drawn but before other studies are resulted is critically important and may represent a practice difference for some emergency physicians when compared with standardized adult care. Unlike adults, all high-risk and most low-risk children with FN undergoing chemotherapy require admission for parenteral antibiotics and monitoring. Oral antibiotic therapy with close, structured outpatient monitoring may be considered only for certain low-risk patients at pediatric centers equipped to pursue this treatment strategy. CONCLUSIONS: Although there are many similarities between the emergency approach to FN in children and adults with cancer, there are differences that every emergency physician should know. This review provides strategies to optimize the care of FN in children with cancer in all emergency practice settings.

Success of Pediatric Intubations Performed by a Critical Care Transport Service.

Background: Prehospital pediatric endotracheal intubation (ETI) is rarely performed. Previous research has suggested that pediatric prehospital ETI, when performed by ground advanced life support crews, is associated with poor outcomes. In this study, we aim to evaluate the first-attempt success rate, overall success rate and complications of pediatric prehospital ETI performed by critical care transport (CCT) personnel.Methods: We conducted a retrospective observational study in a multi-state CCT service performing rotor wing, ground, and fixed wing missions. We included pediatric patients (<18 years) for whom ETI was performed by CCT personnel (flight nurse or flight paramedic).Our primary outcome of interest was rate of first-attempt ETI. Secondary outcomes were overall rates of successful ETI, complications encountered, and outcomes of patients with unsuccessful intubation.Results: 993 patients were included (63.2% male, median age 12 years, IQR 4-16 years). 807/993 (81.3%) patients were intubated on the first attempt. Lower rates of successful first-attempt intubation were seen in younger ages (42.9% in infants ≤30 days of age). In multivariable logistic regression, lower odds (adjusted odds ratio, 95% confidence interval) of successful first-attempt ETI were associated with ages >30 days to <1 year (0.33, 0.18-0.61) and 2 to <6 years (0.60, 0.39-0.94) compared to patients 12 to <18 years. Patients given an induction agent and neuromuscular blockade (NMB) had a higher odds of first-attempt ETI success (1.53, 1.06-2.15). 13 (1.3%) had immediately recognized esophageal intubation and 33 (3.3%) had vomiting. No episodes of pneumothorax were reported. 962/993 (96.9%) patients were successfully intubated after all attempts. In patients without successful ETI (n = 31), supraglottic airways were used in 24, bag-valve mask ventilation in 5, and surgical cricothyroidotomy in 2, with an overall advanced airway success rate of 988/993 (99.5%).Conclusion: Critical care flight nurses and paramedics performed successful intubations in pediatric patients at a high rate of success. Younger age was associated with lower success rates. Improved ETI training for younger patients and use of an induction agent and NMB may improve airway management in critically ill children.

Pediatric Dog Bite Prevention: Are We Barking Up the Wrong Tree or Just Not Barking Loud Enough?

OBJECTIVES: The objectives of this study were (1) to evaluate dog bite-related injuries and associated medical documentation and (2) to compare these results with a study of dog bites from the same institution 10 years prior. METHODS: Data were retrospectively collected from a pediatric emergency department from July 2007 to July 2011 for patients treated for dog bites. These data were then compared with data from the same institution from 10 years prior. RESULTS: A total of 1017 bite injuries were treated (average, 254.25 bites/year), which represents a 25% increase compared with 10 years prior. Comparing the 1997 and 2007 to 2011 cohorts, patient demographics, bite rate among children less than 5 years old, rate of dog breed documentation, and setting of injury were similar. Dog breed was reported in 47% (95% confidence interval [CI], 40.2-53.9) and 41% (95% CI, 38.0-44.0) of cases, respectively, in the 2 cohorts. Bites to the craniofacial region were most common (face only reported for 1997: 43.2%; 95% CI, 36.4-50 versus 2007-2011: 66.1%; 95% CI, 63.2-69.0). In both cohorts, the child's home was the most frequent setting, accounting for 43% of bites (1997: 95% CI, 30.2-55.9 and 2007-2011: 95% CI, 39.3-46.7). CONCLUSIONS: Pediatric dog bites continue to occur frequently, and the associated factors did not change over the 10-year period: young age of child, bites to the craniofacial region, and dogs familiar to the child. Although accurate medical documentation of dog bites is a prerequisite to develop effective prevention strategies, current medical documentation of dog bites may be misguided.

Integration of physical abuse clinical decision support into the electronic health record at a Tertiary Care Children's Hospital.

Objective: To evaluate the effect of a previously validated electronic health record-based child abuse trigger system on physician compliance with clinical guidelines for evaluation of physical abuse. Methods: A randomized controlled trial (RCT) with comparison to a preintervention group was performed. RCT-experimental subjects' providers received alerts with a direct link to a physical abuse-specific order set. RCT-control subjects' providers had no alerts, but could manually search for the order set. Preintervention subjects' providers had neither alerts nor access to the order set. Compliance with clinical guidelines was calculated. Results: Ninety-nine preintervention subjects and 130 RCT subjects (73 RCT-experimental and 57 RCT-control) met criteria to undergo a physical abuse evaluation. Full compliance with clinical guidelines was 84% pre-intervention, 86% in RCT-control group, and 89% in RCT-experimental group. The physical abuse order set was used 43 times during the 7-month RCT. When the abuse order set was used, full compliance was 100%. The proportion of cases in which there was partial compliance decreased from 10% to 3% once the order set became available (P = .04). Male gender, having >10 years of experience and completion of a pediatric emergency medicine fellowship were associated with increased compliance. Discussion/Conclusion: A child abuse clinical decision support system comprised of a trigger system, alerts and a physical abuse order set was quickly accepted into clinical practice. Use of the physical abuse order set always resulted in full compliance with clinical guidelines. Given the high baseline compliance at our site, evaluation of this alert system in hospitals with lower baseline compliance rates will be more valuable in assessing the efficacy in adherence to clinical guidelines for the evaluation of suspected child abuse.

Adenosine Administration With a Stopcock Technique Delivers Lower-Than-Intended Drug Doses.

STUDY OBJECTIVE: Adenosine administration with a stopcock is the recommended treatment for pediatric patients with acute supraventricular tachycardia. Recent reports suggest that many infants do not respond to the first dose of adenosine administered. Our aim is to determine whether administration of adenosine with a stopcock delivers lower-than-expected drug doses in patients weighing less than 10 kg, corresponding to weights of infants. METHODS: We developed an in vitro model of adenosine delivery. Doses of adenosine corresponding to weights 2 to 25 kg were calculated, using a dose of 0.1 mg/kg, and administered through one port of a stopcock. Distilled water was administered through the second port. The adenosine concentration of the output was measured with mass spectrometry and results were confirmed with spectrophotometry of Evans blue. RESULTS: The mean doses of adenosine delivered through the stopcock increased as weight increased. The mean dose of adenosine delivered was 0.08 mg/kg for weights 2 to 9 kg and 0.1 mg/kg for weights 10 to 25 kg (95% confidence interval for difference of means -0.03 to -0.009). The median dose of adenosine delivered was 0.07 mg/kg (interquartile range [IQR] 0.06 to 0.07 mg/kg), 0.09 mg/kg (IQR 0.08 to 0.09 mg/kg), and 0.1 mg/kg (IQR 0.09 to 0.1 mg/kg) for weights 2 to 5, 6 to 9, and 10 to 25 kg, respectively (rank difference=100; P<.05 for 2 to 5 kg versus 10 to 25 kg). Similar results were obtained with spectrophotometry. CONCLUSION: Administration of adenosine through a stopcock delivers doses lower than intended in patients weighing less than 10 kg, which may account for the decreased response of infants to the first dose of adenosine.

Development of an electronic medical record-based child physical abuse alert system.

Objective: Physical abuse is a leading cause of pediatric morbidity and mortality. Physicians do not consistently screen for abuse, even in high-risk situations. Alerts in the electronic medical record may help improve screening rates, resulting in early identification and improved outcomes. Methods: Triggers to identify children < 2 years old at risk for physical abuse were coded into the electronic medical record at a freestanding pediatric hospital with a level 1 trauma center. The system was run in "silent mode"; physicians were unaware of the system, but study personnel received data on children who triggered the alert system. Sensitivity, specificity, and negative and positive predictive values of the child abuse alert system for identifying physical abuse were calculated. Results: Thirty age-specific triggers were embedded into the electronic medical record. From October 21, 2014, through April 6, 2015, the system was in silent mode. All 226 children who triggered the alert system were considered subjects. Mean (SD) age was 9.1 (6.5) months. All triggers were activated at least once. Sensitivity was 96.8% (95% CI, 92.4-100.0%), specificity was 98.5% (95% CI, 98.3.5-98.7), and positive and negative predictive values were 26.5% (95% CI, 21.2-32.8%) and 99.9% (95% CI, 99.9-100.0%), respectively, for identifying children < 2 years old with possible, probable, or definite physical abuse. Discussion/Conclusion: Triggers embedded into the electronic medical record can identify young children with who need to be evaluated for physical abuse with high sensitivity and specificity.

Feasibility of the Digital Retinography System Camera in the Pediatric Emergency Department.

PURPOSE: Direct ophthalmoscopy may be difficult without pupillary dilation and patient cooperation. Nonmydriatic ocular fundus photography (NMOFP) has been shown to be easily and efficiently accomplished by medical providers and improve the detection of abnormalities in adult emergency department (ED) patients. Nonmydriatic ocular fundus photography for pediatric ED patients has not been studied. The purpose of this study was to assess the ease of use of the Digital Retinography System (DRS) camera for NMOFP in ED patients aged 5 to 12 years and the quality of retinal images obtained with the DRS. METHODS: Retinal images were obtained with the DRS by a pediatric emergency medicine physician using a convenience sample of ED patients aged 5 to 12 years. Time to procedure completion, patient cooperation (Likert scale 1-5, with 5 being most cooperative), and satisfaction with the images (Likert scale 1-5, with 5 being completely satisfied) were recorded. Any satisfaction score less than 5 required the physician to describe a reason for dissatisfaction (brightness, field of view, focus). An ophthalmologist was consulted regarding any abnormal image. The accompanying parent completed a survey following the procedure. Estimated time to completion of the procedure and a rating of the overall comfort and cooperation of the child during the procedure (Likert scale 1-5) were recorded. A second pediatric emergency medicine physician reviewed all images and rated the level of satisfaction, reasons for dissatisfaction, and whether the images were normal. Descriptive statistics were used to analyze survey responses. A Mann-Whitney U test was used to compare continuous data for age groups 5 to 8 and 9 to 12 years. A Krippendorff α or κ coefficient was used to measure agreement between the physician obtaining the images and the secondary reviewer for image satisfaction and image abnormalities. RESULTS: One hundred three patients were enrolled: 50 aged 5 to 8 years and 53 aged 9-12 years (mean, 9.1 [SD, 2.1] years). Five patients failed to cooperate, and no images were obtained. The mean length of time (LOT) to procedure completion was 1.8 (SD, 0.86) minutes. Overall, mean cooperation score was 4.4, and mean image satisfaction score was 4.6. One or more reasons for image dissatisfaction were given in 27 patients (imperfect focus most commonly). There was moderate agreement between the 2 physicians for image satisfaction (Krippendorff α coefficient = 0.48) and image abnormalities (κ coefficient = 0.38). Mean LOT did not differ between 5- to 8-year-olds and 9- to 12-year-olds (P = 0.23). Older patients had higher mean cooperation scores and image satisfaction scores (P < 0.001 and P = 0.04 respectively). Parental mean score for perceived LOT was 4.6 (5 = very short), 4.8 for patient comfort (5 = very comfortable), and 4.8 for patient cooperation (5 = very cooperative). CONCLUSIONS: Our data suggest that NMOFP using the DRS camera is a rapid and easy method of obtaining high-quality images of the retina in pediatric ED patients.

Clinician Attitudes Toward Adoption of Pediatric Emergency Telemedicine in Rural Hospitals.

OBJECTIVE: Although there is growing evidence regarding the utility of telemedicine in providing care for acutely ill children in underserved settings, adoption of pediatric emergency telemedicine remains limited, and little data exist to inform implementation efforts. Among clinician stakeholders, we examined attitudes regarding pediatric emergency telemedicine, including barriers to adoption in rural settings and potential strategies to overcome these barriers. METHODS: Using a sequential mixed-methods approach, we first performed semistructured interviews with clinician stakeholders using thematic content analysis to generate a conceptual model for pediatric emergency telemedicine adoption. Based on this model, we then developed and fielded a survey to further examine attitudes regarding barriers to adoption and strategies to improve adoption. RESULTS: Factors influencing adoption of pediatric emergency telemedicine were identified and categorized into 3 domains: contextual factors (such as regional geography, hospital culture, and individual experience), perceived usefulness of pediatric emergency telemedicine, and perceived ease of use of pediatric emergency telemedicine. Within the domains of perceived usefulness and perceived ease of use, belief in the relative advantage of telemedicine was the most pronounced difference between telemedicine proponents and nonproponents. Strategies identified to improve adoption of telemedicine included patient-specific education, clinical protocols for use, decreasing response times, and simplifying the technology. CONCLUSIONS: More effective adoption of pediatric emergency telemedicine among clinicians will require addressing perceived usefulness and perceived ease of use in the context of local factors. Future studies should examine the impact of specific identified strategies on adoption of pediatric emergency telemedicine and patient outcomes in rural settings.

Pediatric Necrotizing Pneumonia: A Case Report and Review of the Literature.

Necrotizing pneumonias occur infrequently in children but may be associated with significant morbidity. If not adequately treated, necrotizing pneumonia may lead to complications including bronchopleural fistula, empyema, respiratory failure, and septic shock. Staphylococcus aureus is the most commonly implicated agent, followed by Streptococcus pneumoniae. Antimicrobial treatment is the cornerstone of management, although surgical drainage may be required in some cases. We present the case of a 14-month-old child with fever and cough that persisted despite treatment with typical first-line oral antimicrobial therapy. An initial plain radiograph of the chest demonstrated lobar pneumonia. Ultimately, computed tomography of the chest revealed a cavitary lesion in the left upper lobe of the lung. We review the literature and describe the clinical presentation, diagnosis, microbiological etiology, and management of necrotizing pneumonia in children.

Pediatric Patient With Altered Mental Status and Hypoxemia: Case Report.

Childhood cases of myxedema coma are extremely rare. We report a case of a 5-year-old girl transferred to a tertiary care pediatric emergency department with hypoxemia and altered mental status and diagnosed with severe hypothyroidism and myxedema coma in the setting of acute influenza infection. Although it is rare, myxedema coma must remain in the differential diagnosis for altered mental status and organ dysfunction in the pediatric population.

Acute Management of Refractory and Unstable Pediatric Supraventricular Tachycardia.

OBJECTIVE: To characterize the management of acute pediatric supraventricular tachycardia (SVT), placing special emphasis on infants, patients refractory to adenosine (refractory SVT), and patients with hypotension, poor perfusion, or altered mental status (unstable SVT). STUDY DESIGN: Retrospective cohort study of patients 0-18 years of age without congenital heart disease who presented to our pediatric hospital from January 2003 to December 2012 for the treatment of acute SVT. Multiple logistic regression was applied to identify whether age was a risk factor for different SVT therapies. Model fit and residuals also were examined. RESULTS: We identified 179 episodes for SVT. First dose of adenosine was effective in 72 (56%) episodes, and a second dose was effective in 27 of 54 (50%) episodes, leaving 27 (15%) episodes with refractory SVT. The response to the first dose of adenosine increased proportionally with age (OR 1.13, 95% CI 1.05-1.2). Only 1 of 17 episodes in infants responded to the first dose of adenosine. Refractory SVT was more frequent in infants vs older children (χ2 = 5.9 [1 df], P = .01). Unstable SVT was present in 13 episodes and was treated with adenosine and antiarrhythmics. Synchronized cardioversion was performed on 3 patients, 2 patients with unstable SVT, and 1 with refractory SVT. CONCLUSION: In children with SVT, young age is associated with decreased response to the first dose of adenosine and increased odds of adenosine-refractory SVT. In the treatment of unstable SVT, medical management with various antiarrhythmics before cardioversion may have a role in a subset of patients. Synchronized cardioversion rarely is performed for acute SVT.

Comparison of Physician Implicit Racial Bias Toward Adults Versus Children.

BACKGROUND AND OBJECTIVES: The general population and most physicians have implicit racial bias against black adults. Pediatricians also have implicit bias against black adults, albeit less than other specialties. There is no published research on the implicit racial attitudes of pediatricians or other physicians toward children. Our objectives were to compare implicit racial bias toward adults versus children among resident physicians working in a pediatric emergency department, and to assess whether bias varied by specialty (pediatrics, emergency medicine, or other), gender, race, age, and year of training. METHODS: We measured implicit racial bias of residents before a pediatric emergency department shift using the Adult and Child Race Implicit Association Tests (IATs). Generalized linear models compared Adult and Child IAT scores and determined the association of participant demographics with Adult and Child IAT scores. RESULTS: Among 91 residents, we found moderate pro-white/anti-black bias on both the Adult (mean = 0.49, standard deviation = 0.34) and Child Race IAT (mean = 0.55, standard deviation = 0.37). There was no significant difference between Adult and Child Race IAT scores (difference = 0.06, P = .15). Implicit bias was not associated with resident demographic characteristics, including specialty. CONCLUSIONS: This is the first study demonstrating that resident physicians have implicit racial bias against black children, similar to levels of bias against black adults. Bias in our study did not vary by resident demographic characteristics, including specialty, suggesting that pediatric residents are as susceptible as other physicians to implicit bias. Future studies are needed to explore how physicians' implicit attitudes toward parents and children may impact inequities in pediatric health care.

Validation of the Pittsburgh Infant Brain Injury Score for Abusive Head Trauma.

BACKGROUND: Abusive head trauma is the leading cause of death from physical abuse. Misdiagnosis of abusive head trauma as well as other types of brain abnormalities in infants is common and contributes to increased morbidity and mortality. We previously derived the Pittsburgh Infant Brain Injury Score (PIBIS), a clinical prediction rule to assist physicians deciding which high-risk infants should undergo computed tomography of the head. METHODS: Well-appearing infants 30 to 364 days of age with temperature <38.3°C, no history of trauma, and a symptom associated with an increased risk of having a brain abnormality were eligible for enrollment in this prospective, multicenter clinical prediction rule validation. By using a predefined neuroimaging paradigm, subjects were classified as cases or controls. The sensitivity, specificity, and negative and positive predictive values of the rule for prediction of brain injury were calculated. RESULTS: A total of 1040 infants were enrolled: 214 cases and 826 controls. The 5-point PIBIS included abnormality on dermatologic examination (2 points), age ≥3.0 months (1 point), head circumference >85th percentile (1 point), and serum hemoglobin <11.2g/dL (1 point). At a score of 2, the sensitivity and specificity for abnormal neuroimaging was 93.3% (95% confidence interval 89.0%-96.3%) and 53% (95% confidence interval 49.3%-57.1%), respectively. CONCLUSIONS: Our data suggest that the PIBIS accurately identifies infants who would benefit from neuroimaging to evaluate for brain injury. An implementation analysis is needed before the PIBIS can be integrated into clinical practice.

Diastolic Hypotension, Troponin Elevation, and Electrocardiographic Changes Associated With the Management of Moderate to Severe Asthma in Children.

OBJECTIVE: The objective was to determine the occurrence of, and the factors associated with, diastolic hypotension and troponin elevation or electrocardiogram (ECG) ST-segment changes in a convenience sample of children with moderate to severe asthma receiving continuous albuterol nebulization. METHODS: This was a prospective, descriptive study in a pediatric emergency department and an intensive care unit of a tertiary academic center. Fifty children with moderate to severe asthma (clinical asthma score > 8) who received 10 to 15 mg/hour continuous albuterol for >2 hours between June 5, 2007, and February 4, 2008, were approached. Hourly diastolic blood pressures were recorded. Cardiac troponin I (cTnI) and ECG tracings were obtained following the first 2 hours of albuterol and then subsequently every 12 hours while receiving continuous albuterol. Main outcome measures were: 1) incidence of diastolic hypotension, 2) incidence of troponin elevation, and 3) incidence of ECG ST-depression. RESULTS: Fifty patients were enrolled. Thirty-three (66%) patients developed diastolic hypotension during the first 6 hours of continuous albuterol. Diastolic blood pressure declined from baseline at 1-6 hours (p < 0.01 vs. baseline). Twelve patients (24%) had elevated cTnI, 15 patients (30%) had ST-segment change, four patients (8%) had both, and 23 patients (46%, 95% confidence interval [CI] = 32 to 60) had either a cTnI elevation or an ECG ST-segment change. Troponin elevation and diastolic hypotension were not associated (RR = 1.2, 95% CI = 0.6 to 2.3). CONCLUSIONS: In a subset of children with moderate to severe asthma, diastolic hypotension, troponin elevation, and ECG ST-segment change occur during administration of continuous albuterol. Future studies are necessary to determine the clinical significance of these findings.

Quality Care and Patient Safety in the Pediatric Emergency Department.

Over the past 15 years, with alarming and illustrative reports released from the Institute of Medicine, quality improvement and patient safety have come to the forefront of medical care. This article reviews quality improvement frameworks and methodology and the use of evidence-based guidelines for pediatric emergency medicine. Top performance measures in pediatric emergency care are described, with examples of ongoing process and quality improvement work in our pediatric emergency department.

The Impact of Cognitive Stressors in the Emergency Department on Physician Implicit Racial Bias.

OBJECTIVES: The emergency department (ED) is characterized by stressors (e.g., fatigue, stress, time pressure, and complex decision-making) that can pose challenges to delivering high-quality, equitable care. Although it has been suggested that characteristics of the ED may exacerbate reliance on cognitive heuristics, no research has directly investigated whether stressors in the ED impact physician racial bias, a common heuristic. We seek to determine if physicians have different levels of implicit racial bias post-ED shift versus preshift and to examine associations between demographics and cognitive stressors with bias. METHODS: This repeated-measures study of resident physicians in a pediatric ED used electronic pre- and postshift assessments of implicit racial bias, demographics, and cognitive stressors. Implicit bias was measured using the Race Implicit Association Test (IAT). Linear regression models compared differences in IAT scores pre- to postshift and determined associations between participant demographics and cognitive stressors with postshift IAT and pre- to postshift difference scores. RESULTS: Participants (n = 91) displayed moderate prowhite/antiblack bias on preshift (mean ± SD = 0.50 ± 0.34, d = 1.48) and postshift (mean ± SD = 0.55 ± 0.39, d = 1.40) IAT scores. Overall, IAT scores did not differ preshift to postshift (mean increase = 0.05, 95% CI = -0.02 to 0.14, d = 0.13). Subanalyses revealed increased pre- to postshift bias among participants working when the ED was more overcrowded (mean increase = 0.09, 95% CI = 0.01 to 0.17, d = 0.24) and among those caring for >10 patients (mean increase = 0.17, 95% CI = 0.05 to 0.27, d = 0.47). Residents' demographics (including specialty), fatigue, busyness, stressfulness, and number of shifts were not associated with postshift IAT or difference scores. In multivariable models, ED overcrowding was associated with greater postshift bias (coefficient = 0.11 per 1 unit of NEDOCS score, SE = 0.05, 95% CI = 0.00 to 0.21). CONCLUSIONS: While resident implicit bias remained stable overall preshift to postshift, cognitive stressors (overcrowding and patient load) were associated with increased implicit bias. Physicians in the ED should be aware of how cognitive stressors may exacerbate implicit racial bias.
