Characterization of Febrile Neutropenia Management in Children With Malignancies: A Single-Center Evaluation.

OBJECTIVE: Current recommendations for febrile neutropenia (FN) include initiation of broad-spectrum antibiotics without clear indications of when or how to de-escalate or target therapy, especially in those without microbiologically defined bloodstream infections (MD-BSIs). The purpose of this study is to characterize a pediatric FN population, FN management, and identify the proportion of patients with MD-BSI. METHODS: This study was a single-center, retrospective chart review of patients admitted to the University of North Carolina Children's Hospital between January 1, 2016, and December 31, 2019, with a diagnosis of FN. RESULTS: There were 81 unique encounters included in this study. MD-BSI was the etiology of fever in 8 FN episodes (9.9%). The most common empiric antibiotic regimen was cefepime (62%) followed by cefepime and vancomycin (25%). The most common de-escalation type was the discontinuation of vancomycin (83.3%), and the most common type of escalation was the addition of vancomycin (50%). The median antibiotic total duration in patients without MDI-BSI was 3 days (IQR, 5-9). CONCLUSIONS: In this single-center, retrospective review, most FN episodes were not due to an MD-BSI. There were inconsistencies in practice of when discontinuation of antibiotic therapy occurred in patients without MD-BSI. De-escalation or cessation of antibiotic therapy before neutropenia resolution did not result in any documented complication. These data suggest a role for implementing an institutional guideline to improve consistency in antimicrobial use in pediatric patients with febrile neutropenia.

Predictors of Partial Hospital Readmission for Young Children with Oppositional Defiant Disorder.

This study aimed to: (1) examine rates of readmission among young children with oppositional defiant disorder (ODD) following discharge from a psychiatric partial hospital treatment program, and (2) examine child factors (i.e., age, sex, co-occurring diagnoses, suicidality) and family factors (i.e., parental depression, stress) as prospective predictors of readmission. Participants were 261 children (ages 3-7 years) who entered the study at the time of their initial program admission and who met DSM-IV criteria for ODD. Of these 261 children, 61 (23%) were subsequently readmitted, with most readmissions occurring within 1 year. Cox regression survival analyses demonstrated that younger child age, child suicidal thoughts and behavior, and child PTSD diagnosis were associated with decreased time to readmission. Findings suggest that young children with ODD who present with co-occurring suicidality or PTSD are at risk for readmission following partial hospitalization, with implications for treatment and aftercare planning.

Temper Loss and Persistent Irritability in Preschoolers: Implications for Diagnosing Disruptive Mood Dysregulation Disorder in Early Childhood.

Disruptive Mood Dysregulation Disorder (DMDD) is a new and controversial child psychiatric disorder characterized by persistent irritability and frequent temper loss. Among the controversies surrounding DMDD is whether the age of onset criterion-that DMDD may not be diagnosed before age 6 years-is justified. This study examined DMDD symptoms and associated patterns of psychiatric comorbidity, behavioral, and family functioning in a sample of 139 preschoolers (ages 4-0 to 5-11 years) admitted to an early childhood psychiatric day treatment program. DMDD symptoms were common in this acute clinical sample, with 63 children (45.3 %) presenting with frequent temper outbursts and chronic irritability. As compared to children who did not present with DMDD symptoms, these children demonstrated more aggression and emotional reactivity and lower receptive language skills, with high rates of comorbidity with the disruptive behavior disorders. Findings contribute to an emerging literature on preschool DMDD, with implications for early childhood psychiatric assessment and clinical interventions.

Suicidal thoughts and behaviors in psychiatrically referred young children.

Despite increased awareness of the prevalence and seriousness of mental health problems in early childhood, there have been few empirical studies of suicidal thoughts and behaviors in this age group. This study examined suicidal thoughts and behaviors in 360 preschool-aged children (ages 3 to 7 years) presenting to a psychiatric day treatment program. A semi-structured diagnostic interview (conducted with primary caregivers) was used to assess for child suicidal thoughts and behaviors and psychiatric disorders. Participating mothers also reported on their own psychological distress and family psychiatric history. Forty-eight children (13%) were reported to have suicidal thoughts and behaviors, with suicidal plans or attempts endorsed for 2-3% of the sample. Suicidal thinking and behavior was associated with older child age and with higher rates of concurrent depression, oppositional defiant disorder, and posttraumatic stress disorder in univariate analyses, with age and depression remaining as significant predictors in a multivariate logistic regression model. Findings suggest that suicidal thoughts and behaviors are a significant clinical concern for young children presenting with early psychopathology, particularly depression, with implications for early childhood psychiatric assessment and treatment.

Adverse Events in Very Young Children Prescribed Psychotropic Medications: Preliminary Findings from an Acute Clinical Sample.

OBJECTIVE: The present study used the Pediatric Adverse Events Rating Scale (PAERS) to provide a systematic assessment of adverse events (AEs) related to psychotropic medication use in a clinical sample of young children attending a specialized, early childhood partial hospital program. Study goals were as follows: 1) To describe the frequency and types of specific psychotropic medication-related AEs experienced by very young children (ages 3-7 years) in an acute clinical sample, and 2) to identify the psychotropic medication(s) and/or class(es) associated with the highest frequency of AEs. METHODS: Participants were 158 children (118 males; ages 36-95 months, mean=66 months, SD=14.6 months) who presented to a hospital-based day treatment program for young children with severe emotional and behavioral problems, and were prescribed a psychotropic medication at any point during the hospitalization. Data on AEs related to psychotropic medication were collected using the PAERS from 2011 to 2014. RESULTS: The percentages of children who experienced one or more AEs attributed to a psychiatric medication ranged from 0 (sertraline, melatonin) to 41.2% (fluoxetine), with wide variability in the types AEs reported. The overall frequencies of events caused by a stimulant were similar across the two medications examined (21.4% and 27.7% for mixed amphetamine salts and methylphenidate, respectively), with mood-related difficulties and decreased appetite being the most common AEs reported. The frequencies of AEs caused by an α agonist were also similar across the two medications examined (9.8% and 17.2% for guanfacine and clonidine, respectively), with fatigue as the most commonly reported AE. With respect to the selective serotonin reuptake inhibitor (SSRI) class, there was a trend for fluoxetine to be associated with more AEs (41.2%) than sertraline (for which no AEs were reported). The most common AEs reported for fluoxetine were impulsivity and poor concentration. CONCLUSIONS: The data presented here support existing literature reporting differences in AEs between age groups. More rigorous studies are warranted to further examine the types and frequencies of AEs related to psychotropic medications in very young children.
