Race, Ethnicity, Language, and the Treatment of Low-Risk Febrile Infants

Importance

Febrile infants at low risk of invasive bacterial infections are unlikely to benefit from lumbar puncture, antibiotics, or hospitalization, yet these are commonly performed. It is not known if there are differences in management by race, ethnicity, or language.

Objective

To investigate associations between race, ethnicity, and language and additional interventions (lumbar puncture, empirical antibiotics, and hospitalization) in well-appearing febrile infants at low risk of invasive bacterial infection.

Design, Setting, and Participants

This was a multicenter retrospective cross-sectional analysis of infants receiving emergency department care between January 1, 2018, and December 31, 2019. Data were analyzed from December 2022 to July 2023. Pediatric emergency departments were determined through the Pediatric Emergency Medicine Collaborative Research Committee. Well-appearing febrile infants aged 29 to 60 days at low risk of invasive bacterial infection based on blood and urine testing were included. Data were available for 9847 infants, and 4042 were included following exclusions for ill appearance, medical history, and diagnosis of a focal infectious source.

Exposures

Infant race and ethnicity (non-Hispanic Black, Hispanic, non-Hispanic White, and other race or ethnicity) and language used for medical care (English and language other than English).

Main Outcomes and Measures

The primary outcome was receipt of at least 1 of lumbar puncture, empirical antibiotics, or hospitalization. We performed bivariate and multivariable logistic regression with sum contrasts for comparisons. Individual components were assessed as secondary outcomes.

Results

Across 34 sites, 4042 infants (median [IQR] age, 45 [38-53] days; 1561 [44.4% of the 3516 without missing sex] female; 612 [15.1%] non-Hispanic Black, 1054 [26.1%] Hispanic, 1741 [43.1%] non-Hispanic White, and 352 [9.1%] other race or ethnicity; 3555 [88.0%] English and 463 [12.0%] language other than English) met inclusion criteria. The primary outcome occurred in 969 infants (24%). Race and ethnicity were not associated with the primary composite outcome. Compared to the grand mean, infants of families that use a language other than English had higher odds of the primary outcome (adjusted odds ratio [aOR]; 1.16; 95% CI, 1.01-1.33). In secondary analyses, Hispanic infants, compared to the grand mean, had lower odds of hospital admission (aOR, 0.76; 95% CI, 0.63-0.93). Compared to the grand mean, infants of families that use a language other than English had higher odds of hospital admission (aOR, 1.08; 95% CI, 1.08-1.46).

Conclusions and Relevance

Among low-risk febrile infants, language used for medical care was associated with the use of at least 1 nonindicated intervention, but race and ethnicity were not. Secondary analyses highlight the complex intersectionality of race, ethnicity, language, and health inequity. As inequitable care may be influenced by communication barriers, new guidelines that emphasize patient-centered communication may create disparities if not implemented with specific attention to equity.

Caregivers' Experiences During the COVID-19 Pandemic and Their Children's Behavior

The COVID-19 pandemic has financial and emotional impacts on families. We explored how caregivers' financial strain and mental health are associated with changes in their young children's behavior during the pandemic. We additionally considered whether having a sense of purpose moderated these associations. Caregivers (n = 300) in the emergency department of a children's hospital were surveyed anonymously about changes to their employment (e.g., reduced/increased hours and job loss), ability to pay for expenses and whether their child's behavior had changed. Aligned with the Family Stress Model, caregivers' financial strain was associated with poor mental health, inconsistent sleep routines, and changes in children's problematic and prosocial behaviors. A sense of purpose buffered some of these relationships. Families are differently affected by the pandemic and our findings underscore the need for supporting caregivers' mental health and connecting them with resources.

A Case Report of Neonatal Vomiting due to Adrenal Hemorrhage, Abscess and Pseudohypoaldosteronism

Neonatal adrenal hemorrhage is a rare phenomenon which may occur in utero or in the intrapartum period. This case illustrates ultrasound and subsequent abdominal computed tomography (CT) imaging of a 30-day-old neonate who initially presented with acute vomiting and was found to have an abscess at the site of a previous right-sided adrenal hemorrhage. Ultrasound-guided fine needle aspiration of the abscess was ultimately the key diagnostic and therapeutic intervention, which detected Escherichia coli (E. coli) infection. The discussion addresses the connection between key pathologic features of this case, while reviewing the acute management of clinical sequelae in the emergency department.

Topics

Neonatal vomiting, adrenal hemorrhage, retroperitoneal abscess, pseudohypoaldosteronism.

Development and validation of an early warning tool for sepsis and decompensation in children during emergency department triage

This study was designed to develop and validate an early warning system for sepsis based on a predictive model of critical decompensation. Data from the electronic medical records for 537,837 visits to a pediatric Emergency Department (ED) from March 2013 to December 2019 were collected. A multiclass stochastic gradient boosting model was built to identify early warning signs associated with death, severe sepsis, non-severe sepsis, and bacteremia. Model features included triage vital signs, previous diagnoses, medications, and healthcare utilizations within 6 months of the index ED visit. There were 483 patients who had severe sepsis and/or died, 1102 had non-severe sepsis, 1103 had positive bacteremia tests, and the remaining had none of the events. The most important predictors were age, heart rate, length of stay of previous hospitalizations, temperature, systolic blood pressure, and prior sepsis. The one-versus-all area under the receiver operator characteristic curve (AUROC) were 0.979 (0.967, 0.991), 0.990 (0.985, 0.995), 0.976 (0.972, 0.981), and 0.968 (0.962, 0.974) for death, severe sepsis, non-severe sepsis, and bacteremia without sepsis respectively. The multi-class macro average AUROC and area under the precision recall curve were 0.977 and 0.316 respectively. The study findings were used to develop an automated early warning decision tool for sepsis. Implementation of this model in pediatric EDs will allow sepsis-related critical decompensation to be predicted accurately after a few seconds of triage.

Febrile Seizure Team-based Learning

Audience

This modified team-based learning (mTBL) is designed for junior and senior emergency medicine and pediatric residents.

Introduction/Background

Febrile seizures are the most common cause of seizures in children under 5 years old and are frequently evaluated in the emergency department.1,2 Febrile seizures can be frightening for parents to witness and often necessitate extensive parental reassurance and education by the emergency medicine (EM) provider. Most febrile seizures are brief, do not require a broad workup, and have a benign prognosis. With introduction of conjugate vaccines for Haemophilus influenzae type B (Hib) and Streptococcus pneumoniae in the United States in 1987 and 2000 respectively, the incidence of bacterial meningitis is low, but still present.3-7 The most recent American Academy of Pediatrics practice guidelines no longer recommend routine lumbar puncture on children presenting with simple febrile seizures.2 A review of the current literature shows that bacterial meningitis in children after a complex febrile seizure is unexpected when the clinical examination is not suggestive of meningitis or encephalitis.5-8 The goal of this mTBL is for residents to feel comfortable counseling parents about their child currently in the emergency department and the future risk of recurrence. The second goal is for residents to identify which patients presenting with fever and a seizure do require workup beyond simply identifying the source of the fever.

Educational Objectives

By the end of this educational session, the learner will:List the characteristics of a simple febrile seizure.Discuss the management of a child with a simple vs. complex febrile seizure.Discuss the risk factors that correlate with an increased risk of a subsequent febrile seizure.Determine when a lumbar puncture should be considered in a febrile child with a seizure.Identify when to give anti-epileptics and construct an algorithm for their use.Discuss with parents, provide education and return precautions.

Educational Methods

This didactic session is a mTBL. The classic learner responsible content (LRC) has been omitted and a short PowerPoint presentation is given to start the session before the individual and group readiness assessment tests.

Research Methods

A post-TBL survey was given to each participant. A Likert scale was used to assess each participant's assessment for the learning session in the following categories: overall, context, quality, and speaker feedback. They were also given fields to enter ways in which they would improve their practice after this learning exercise and suggestions they had for improving the current educational opportunity.

Results

In the pilot session of this mTBL, 4 out of 11 participants (EM residents and pediatric emergency medicine [PEM] fellows) completed the post-TBL survey. Overall, this session was rated as "outstanding" (Likert 5/5) by 1 and "excellent" (Likert 4/5) by 3 for a weighted average of 4.25. All participants completing the survey found the activity "highly relevant," "very engaging," and wanted to repeat the activity in the future. Negative feedback consisted of wanting a video of a child having a seizure to be played and having a more interactive PowerPoint portion of the session like the interaction in the readiness assessment tests and group application exercise.

Discussion

Overall the content was effective as evidenced by the list of ways residents said they would improve their practice on the post-TBL survey. In the future, I would extend the session from 60 minutes to 90 minutes to allow for more time for the group application exercise and discussion of answers. I found this to be an enjoyable, highly interactive experience with high engagement of the residents during the session.

Topics

Simple febrile seizures, complex febrile seizures, seizure with fever, meningitis, lumbar puncture, status epilepticus.

Bilious vomiting does not rule out infantile hypertrophic pyloric stenosis

OBJECTIVE

To describe the incidence of bilious vomiting in infants with infantile hypertrophic pyloric stenosis that presented to a pediatric emergency department.

METHODS

A retrospective medical record review included all infants who presented to our level 1 pediatric emergency department from January 1, 2005, through December 31, 2009, who were diagnosed intraoperatively with infantile hypertrophic pyloric stenosis. Emesis was determined to be bilious if the vomit was described as "green," "containing bile," or "bilious."

RESULTS

The authors identified 354 infants with infantile hypertrophic pyloric stenosis. The median age was 4 weeks 6 days (range = 11 days to 13 weeks). Bilious emesis was encountered in 1.4% (5/354; 95% confidence interval = 0.5% to 3.2%). The pyloric thickness measurements on ultrasound were significantly smaller in those with bilious emesis compared with those without bilious emesis (z score = 2.64; P = .014).

CONCLUSION

Bilious emesis was the presenting symptom in a small proportion of infants with infantile hypertrophic pyloric stenosis.
