Racial and Ethnic Differences in Hospital Admission and Diagnostic Evaluation for Febrile Seizures in the Emergency Department.

OBJECTIVE: To examine differences in hospital admission and diagnostic evaluation for febrile seizure by race and ethnicity. STUDY DESIGN: We conducted a cross-sectional study among children 6 months to 6 years with simple or complex febrile seizure between January 1, 2016, and December 31, 2021, using data from the Pediatric Health Information System. The primary outcome was hospital admission. Secondary outcomes included the proportion of encounters with neuroimaging or lumbar puncture. We used mixed-effects logistic regression model with random intercept for hospital and patient to estimate the association between outcomes and race and ethnicity after adjusting for covariates, including seizure type. RESULTS: In total, 94 884 encounters were included. Most encounters occurred among children of non-Hispanic White (37.0%), Black (23.9%), and Hispanic/Latino (24.6%) race and ethnicity. Black and Hispanic/Latino children had 29% (aOR 0.71; 95% CI 0.66-0.75) and 26% (aOR 0.74; 95% CI 0.69-0.80) lower odds of hospital admission compared with non-Hispanic White children, respectively. Black and Hispanic/Latino children had 21% (aOR 0.79; 95% CI 0.73-0.86) and 22% (aOR 0.78; 95% CI 0.71-0.85) lower adjusted odds of neuroimaging compared with non-Hispanic White children. For complex febrile seizure, the adjusted odds of lumbar puncture was significantly greater among Asian children (aOR 2.12; 95% CI 1.19-3.77) compared with non-Hispanic White children. There were no racial differences in the odds of lumbar puncture for simple febrile seizure. CONCLUSIONS: Compared with non-Hispanic White children, Black and Hispanic/Latino children with febrile seizures are less likely to be hospitalized or receive neuroimaging.

Effect of Prearrival Orders on Time to Antibiotics for Immunocompromised Oncology Patients Presenting to the Emergency Department With Fever.

OBJECTIVE: Pediatric cancer patients with fever are at risk for invasive bacterial infection. The administration of antibiotics to these patients within the first hour of evaluation is viewed as a quality of care metric with potential to improve outcome. We sought to evaluate the impact of prearrival patient orders on the timeliness of antibiotic administration for this patient population presenting to the emergency department (ED) because of fever. METHODS: A single-site pediatric ED intervention study was performed. Four hundred thirty-nine consecutively referred febrile immunocompromised pediatric oncology patients were included in the study. The intervention used structured monthly messages sent to oncology and emergency medicine providers highlighting specific roles in prehospital communication and in ED-based care emphasizing the use of standardized, prearrival order (PAO) sets. Primary outcome measures were time to antibiotic administration (TTA) and the proportions of patients receiving PAO placement and antibiotics within 60 minutes of ED arrival. Results were analyzed for the preintervention (September 2016-July 2017), intervention (August 2017-February 2018), and postintervention (March-December 2018) periods. RESULTS: Improvements occurred across the study periods in the proportion of patients with PAO placement (preintervention, 68%; intervention, 82%; postintervention, 87%; P = 0.001) as well as in the percentages of patients receiving antibiotics in less than 60 minutes (preintervention, 73%; intervention, 84%; postintervention, 85%; P = 0.02). Median TTA decreased from 48 to 40 minutes ( P = 0.018). Linear regression with TTA as a dependent variable revealed that PAO placement predicted a shorter TTA, decreasing by more than 15 minutes ( B = -15.90; [95% confidence interval, -20.03--11.78]; P < 0.001). CONCLUSIONS: Standardizing elements of prehospital communication and ED-based care using PAO sets resulted in significant improvements in time to antibiotics and in the proportion of febrile immunocompromised oncology patients receiving antibiotics within 60 minutes of ED arrival.

Accuracy and Interrater Reliability of Point-of-Care Ultrasonography Image Interpretation for Intussusception.

OBJECTIVES: The aim of this study was to determine the accuracy and interrater reliability of (1) point-of-care ultrasound (POCUS) image interpretation for identification of intussusception and (2) reliability of secondary signs associated with intussusception among experts compared with novice POCUS reviewers. METHODS: We conducted a planned secondary analysis of a prospective, convenience sample of children aged 3 months to 6 years who were evaluated with POCUS for intussusception across 17 international pediatric emergency departments between October 2018 and December 2020. A random sample of 100 POCUS examinations was reviewed by novice and expert POCUS reviewers. The primary outcome was identification of the presence or absence of intussusception. Secondary outcomes included intussusception size and the presence of trapped free fluid or echogenic foci. Accuracy was summarized using sensitivity and specificity, which were estimated via generalized mixed effects logistic regression. Interrater reliability was summarized via Light's κ statistics with bootstrapped standard errors (SEs). Accuracy and reliability of expert and novice POCUS reviewers were compared. RESULTS: Eighteen expert and 16 novice POCUS reviewers completed the reviews. The average expert sensitivity was 94.5% (95% confidence interval [CI], 88.6-97.5), and the specificity was 94.3% (95% CI, 90.3-96.7), significantly higher than the average novice sensitivity of 84.7% (95% CI, 74.3-91.4) and specificity of 80.4% (95% CI, 72.4, 86.7). κ was significantly greater for expert (0.679, SE 0.039) compared with novice POCUS reviewers (0.424, SE 0.044; difference 0.256, SE 0.033). For our secondary outcome measure of intussusception size, κ was significantly greater for experts (0.661, SE 0.038) compared with novices (0.397, SE 0.041; difference 0.264, SE 0.029). Interrater reliability was weak for expert and minimal for novice reviewers regarding the detection of trapped free fluid and echogenic foci. CONCLUSIONS: Expert POCUS reviewers demonstrate high accuracy and moderate interrater reliability when identifying intussusception via image interpretation and perform better than novice reviewers.

Infants distinguish and represent pattern as an object feature from externally generated patterns superimposed on real, 3-dimensional objects' surfaces.

As infants form object representations, the patterns viewed on objects' surfaces may be challenging to decipher because these patterns may be created from the surface reflectance of an object (an object property) or from an external source, such as a cast shadow. We tested 7 ½-month-old infants' use of cues that specify the source of patterns seen on the surfaces of real, 3-dimensional objects to individuate those objects. Results suggest that when forming object representations based on patterns, 7½-month-olds rely heavily on temporal and depth cues to distinguish patterns inherent to the object from other types of patterns.

Children's use of local and global visual features for material perception.

Adults can rapidly recognize material properties in natural images, and children's performance in material categorization tasks suggests that this ability develops slowly during childhood. In the current study, we further examined the information children use to recognize materials during development by asking how the use of local versus global visual features for material perception changes in middle childhood. We recruited adults and 5- to 10-year-old children for three experiments that required participants to distinguish between shape-matched images of real and artificial food. Accurate performance in this task requires participants to distinguish between a wide range of material properties characteristic of each category, thus testing material perception abilities broadly. In two tasks, we applied distinct methods of image scrambling (block scrambling and diffeomorphic scrambling) to parametrically disrupt global appearance while preserving features in small spatial neighborhoods. In the third task, we used image blurring to parametrically disrupt local feature visibility. Our key question was whether or not participant age affected performance differently when local versus global appearance was disrupted. We found that although image blur led to disproportionately poorer performance in young children, this effect was reduced or absent when diffeomorphic scrambling was used. We interpret this outcome as evidence that the ability to recruit large-scale visual features for material perception may develop slowly during middle childhood.

Piloting a Mobile Clinical Decision Support Application for Pediatric Clinical Guidelines.

Mobile Clinical Decision Support Systems (CDSSs) represent an increasingly utilized technology to promote clinical guideline use. We sought to explore clinician guideline use and access preferences during implementation of a mobile guideline app at a free-standing children's hospital integrating 23 guidelines. Surveys included demographic variables and access preferences among anonymous onboarded clinicians in January 2022. Response rate was 21.8% (57/261) among onboarded users, mostly attending (59.6%) and resident/fellow physicians (21.1%) in inpatient (42.1%) and emergency department (31.6%) settings. Onboarded users accessed guidelines on over half of shifts (68.4%) and quickly (80.7%, <1 minute). Overall, most users reported favorable patterns for adoption of mobile CDSSs as useful adjuncts to existing formats. Users reported more ease of access and frequent guideline usage, particularly for younger clinicians. Guidelines related to antibiotic decision-making or newer disease processes were most useful. Further study is needed on electronic health record incorporation, adherence, and patient outcomes.

Impact of Clinical Guidelines on Hospital Utilization in Children With Croup.

OBJECTIVES: To assess the impact of croup guidelines on healthcare utilization and association between guideline-recommended racemic epinephrine (RE) treatments and admission. METHODS: Cross-sectional study of children ≥3 months to ≤8 years with croup diagnosis (International Classification of Diseases, 10th Revision) from 38 hospitals within the Pediatric Health Information System between January 1, 2019 and June 30, 2022. Guidelines were categorized by minimum number of RE treatments recommended before admission. Exclusion criteria included complex chronic or croup mimicking conditions, alternate respiratory diagnoses, and direct admissions or transfers. Primary outcomes were admission rates and standardized costs. Outcomes were compared by guideline availability and different admission thresholds. Mixed effects regression was adjusted for age, sex, race, payer, previous croup encounters, and year. RESULTS: Twenty hospitals (52.6%) had guidelines. Fourteen recommended 2 RE treatments and 3 recommended 3 RE treatment before admission. Among 121 284 croup encounters, overall mean admission rate was 5.7% (range 0.6% to 18.5%). Hospitals with guidelines demonstrated lower unadjusted admission rate (4.6% vs 6.6%; mean difference -2.0, 95% confidence interval -2.3 to -1.7) and higher costs ($704 vs $651; mean difference 53, 95% confidence interval 43 to 63) compared with hospitals without guidelines. Hospitals with guidelines recommending 3 RE treatments demonstrated similar unadjusted mean admission rate (5.1%) and lower costs ($658 vs $713) compared with hospitals with guidelines recommending 2 RE treatments. After adjustment, all above-mentioned differences were not statistically significant. CONCLUSIONS: Many children's hospitals lack guidelines for croup. Admission rates and costs were not significantly different between hospitals with or without guidelines after adjusting for confounders.

Variation in Organizational Clinical Practice Guidelines for Croup.

BACKGROUND: Croup is one of the most common respiratory complaints in pediatric emergency departments (EDs), yet little is known about clinical practice guidelines (CPGs) for this condition. OBJECTIVES: To describe variation in CPGs across US children's hospitals. METHODS: We describe the prevalence and features of CPGs among hospitals that submit data to the Pediatric Health Information System. Each hospital was contacted between January 10, 2022, and April 25, 2022, for their most recent croup CPG and any revisions. Characteristics reported were based on the most recent CPG revision. Characteristics included treatment recommendations, utilization measures, ED observation times, and admission criteria. Interrater reliability between reviewers was reported as percentage agreement. RESULTS: Thirty-eight hospitals (79.2%) responded to our query, of which 20 (52.6%) had croup CPGs. Interrater reliability was moderate-high for categorizing the indication for racemic epinephrine (RE) (19 of 20; 95%), the minimum number of RE doses recommended before admission (15 of 20; 75%), and ED observation time (19 of 20; 95%), and was 100% for all other characteristics. Three CPGs (15.0%) recommended 1 RE dose, 14 (70.0%) recommended 2 RE doses, and 3 (15.0%) recommended 3 RE doses before hospital admission. Thirteen (65%) CPGs recommended RE for stridor at rest, whereas 7 (30%) recommended RE for any degree of stridor. Fourteen (70%) CPGs recommended an ED observation time <2 hours, 3 (15%) recommended 2 to 4 hours, and 2 (10%) recommended >4 hours. Few CPGs (15%) recommended use of standardized croup clinical scores. CONCLUSIONS: Substantial variation exists among croup CPGs. Our results may inform future efforts to standardize croup CPGs across centers.

Explaining Adherence to American Academy of Pediatrics Screen Time Recommendations With Caregiver Awareness and Parental Motivation Factors: Mixed Methods Study.

BACKGROUND: With the increasing integration of technology into society, it is advisable that researchers explore the effects of repeated digital media exposure on our most vulnerable population-infants. Excessive screen time during infancy has been linked to delays in language, literacy, and self-regulation. OBJECTIVE: This study explores the awareness of and adherence to the American Academy of Pediatrics' (AAP) recommendations related to avoiding screen time for infants younger than 2 years and the motivational factors associated with screen time exposure. METHODS: A mixed methods survey design was used to gather responses from 178 mothers of infants younger than 2 years. The measures included infant screen time use and duration, maternal awareness of screen time use recommendations, and motivations related to screen time exposure. A variety of statistical procedures were used to explore associations between caregiver awareness of and adherence to AAP guidelines for screen time exposure, motivations related to screen time for infants, and the duration of infant screen time exposure. RESULTS: The results indicated that 62.2% (111/178) of mothers were aware of the AAP screen time recommendations, but only 46.1% (82/178) could cite them accurately, and most mothers learned of them via the internet or from a medical professional. Mothers who were aware of the guidelines allowed significantly less screen time for infants than those who were unaware (P=.03). In addition, parents who adhered to the AAP guidelines reported significantly less infant screen time per day than those who did not adhere (P<.001). Among mothers who reported not adhering to the guidelines, the greatest motivation for allowing screen time was perceived educational benefits. Less educated mothers rated an infant's relaxation as a motivational factor in allowing screen time significantly higher than more highly educated mothers (P=.048). The regression analysis indicated that none of the parental motivation factors predicted daily infant screen time. CONCLUSIONS: These results indicate 2 key approaches to improving adherence to screen time recommendations. First, the awareness of the AAP recommendations needs to be increased, which tends to improve adherence. Second, the myth that screen time can be educational for infants needs to be dispelled.

Association of Neighborhood Resources and Race and Ethnicity With Readmissions for Diabetic Ketoacidosis at US Children's Hospitals.

Importance: The Child Opportunity Index 2.0 (COI) assesses neighborhood resources and conditions that influence health. It is unclear whether the COI scores are associated with health outcomes by race and ethnicity among children with type 1 diabetes (T1D). Objective: To determine whether COI categories are associated with diabetes-related outcomes by race and ethnicity, including readmissions for diabetic ketoacidosis (DKA) and co-occurring acute kidney injury (AKI) or cerebral edema (CE). Design, Setting, and Participants: This cross-sectional study included children discharged with a primary diagnosis of T1D with DKA between January 1, 2009, and December 31, 2018. Merged data were obtained from the Pediatric Health Information System and COI. Participants included children and adolescents younger than 21 years with an encounter for DKA. Data were analyzed from April 29, 2021, to January 5, 2022. Exposures: Neighborhood opportunity, measured with the COI as an ordered, categorical score (where a higher score indicates more opportunity), and race and ethnicity. Main Outcomes and Measures: The primary outcome was readmission for DKA within 30 and 365 days from an index visit. Secondary outcomes included the proportion of encounters with AKI or CE. Mixed-effects logistic regression was used to generate probabilities of readmission, AKI, and CE for each quintile of COI category by race and ethnicity. Results: A total of 72 726 patient encounters were identified, including 38 924 (53.5%) for girls; the median patient age was 13 (IQR, 9-15) years. In terms of race and ethnicity, 600 (0.8%) of the encounters occurred in Asian patients, 9969 (13.7%) occurred in Hispanic patients, 16 876 (23.2%) occurred in non-Hispanic Black (hereinafter Black) patients, 40 129 (55.2%) occurred in non-Hispanic White (hereinafter White) patients, and 5152 (7.1%) occurred in patients of other race or ethnicity. The probability of readmission within 365 days was significantly higher among Black children with a very low COI category compared with Hispanic children (risk difference, 7.8 [95% CI, 6.0-9.6] percentage points) and White children (risk difference, 7.5 [95% CI, 5.9-9.1] percentage points) at the same COI category. Similar differences were seen for children with very high COI scores and across racial groups. The COI category was not associated with AKI or CE. However, race and ethnicity constituted a significant factor associated with AKI across all COI categories. The probability of AKI was 6.8% among Black children compared with 4.2% among Hispanic children (risk difference, 2.5 [95% CI, 1.7-3.3] percentage points) and 4.8% among White children (risk difference, 2.0 [95% CI, 1.3-2.6] percentage points). Conclusions and Relevance: These results suggest that Black children with T1D experience disparities in health outcomes compared with other racial and ethnic groups with similar COI categories. Measures to prevent readmissions for DKA should include interventions that target racial disparities and community factors.
