Predicting Serious Bacterial Infections Among Hypothermic Infants in the Emergency Department.

BACKGROUND: There is insufficient evidence to guide the initial evaluation of hypothermic infants. We aimed to evaluate risk factors for serious bacterial infections (SBI) among hypothermic infants presenting to the emergency department (ED). METHODS: We conducted a multicenter case-control study among hypothermic (rectal temperature <36.5°C) infants ≤90 days presenting to the ED who had a blood culture collected. Our outcome was SBI (bacteremia, bacterial meningitis, and/or urinary tract infection). We performed 1:2 matching. Historical, physical examination and laboratory covariables were determined based on the literature review from febrile and hypothermic infants and used logistic regression to identify candidate risk factors. RESULTS: Among 934 included infants, 57 (6.1%) had an SBI. In univariable analyses, the following were associated with SBI: age > 21 days, fever at home or in the ED, leukocytosis, elevated absolute neutrophil count, thrombocytosis, and abnormal urinalysis. Prematurity, respiratory distress, and hypothermia at home were negatively associated with SBI. The full multivariable model exhibited a c-index of 0.91 (95% confidence interval: 0.88-0.94). One variable (abnormal urinalysis) was selected for a reduced model, which had a c-index of 0.82 (95% confidence interval: 0.75-0.89). In a sensitivity analysis among hypothermic infants without fever (n = 22 with SBI among 116 infants), leukocytosis, absolute neutrophil count, and abnormal urinalysis were associated with SBI. CONCLUSIONS: Historical, examination, and laboratory data show potential as variables for risk stratification of hypothermic infants with concern for SBI. Larger studies are needed to definitively risk stratify this cohort, particularly for invasive bacterial infections.

Association of Models of Care for Kawasaki Disease With Utilization and Cardiac Outcomes.

OBJECTIVES: Describe the prevalence of different care models for children with Kawasaki disease (KD) and evaluate utilization and cardiac outcomes by care model. METHODS: Multicenter, retrospective cohort study of children aged 0 to 18 hospitalized with KD in US children's hospitals from 2017 to 2018. We classified hospital model of care via survey: hospitalist primary service with as-needed consultation (Model 1), hospitalist primary service with automatic consultation (Model 2), or subspecialist primary service (Model 3). Additional data sources included administrative data from the Pediatric Health Information System database supplemented by a 6-site chart review. Utilization outcomes included laboratory, medication and imaging usage, length of stay, and readmission rates. We measured the frequency of coronary artery aneurysms (CAAs) in the full cohort and new CAAs within 12 weeks in the 6-site chart review subset. RESULTS: We included 2080 children from 44 children's hospitals; 21 hospitals (48%) identified as Model 1, 19 (43%) as Model 2, and 4 (9%) as Model 3. Model 1 institutions obtained more laboratory tests and had lower overall costs (P < .001), whereas echocardiogram (P < .001) and immune modulator use (P < .001) were more frequent in Model 3. Secondary outcomes, including length of stay, readmission rates, emergency department revisits, CAA frequency, receipt of anticoagulation, and postdischarge CAA development, did not differ among models. CONCLUSIONS: Modest cost and utilization differences exist among different models of care for KD without significant differences in outcomes. Further research is needed to investigate primary service and consultation practices for KD to optimize health care value and outcomes.

2021 Update on Pediatric Overuse.

This update on pediatric medical overuse identifies and provides concise summaries of 10 impactful articles related to pediatric medical overuse from the years 2019 to 2020.

2019 Update on Pediatric Medical Overuse: A Systematic Review.

Importance: Medical overuse is common in pediatrics and may lead to unnecessary care, resource use, and patient harm. Timely scrutiny of established and emerging practices can identify areas of overuse and empower clinicians to reconsider the balance of harms and benefits of the medical care that they provide. A literature review was conducted to identify the most important areas of pediatric medical overuse in 2018. Observations: Consistent with prior methods, a structured MEDLINE search and manual table of contents review of selected pediatric journals for the 2018 literature was conducted identifying articles pertaining to pediatric medical overuse. The structured MEDLINE search consisted of a PubMed search for articles with the Medical Subject Headings term health services misuse or medical overuse or article titles containing the term unnecessary, inappropriate, overutilization, or overuse. Articles containing the term overuse injury or overuse injuries were excluded, along with articles not published in English and those not constituting original research. The same search was performed using Embase with the additional Emtree term unnecessary procedure. Each article was evaluated by 3 independent raters for quality of methods, magnitude of potential harm, and number of patients potentially harmed. Ten articles were identified based on scores and appraisal of overall potential harm. This year's review identified both established and emerging practices that may warrant deimplementation. Examples of such established practices include antibiotic prophylaxis for urinary tract infections, routine opioid prescriptions, prolonged antibiotic courses for latent tuberculosis, and routine intensive care admission and pharmacologic therapy for neonatal abstinence syndrome. Emerging practices that merit greater inspection and discouragement of widespread adoption include postdischarge nurse-led home visits, probiotics for gastroenteritis, and intensive cardiac screening programs for athletes. Conclusions and Relevance: This year's review highlights established and emerging practices that represent medical overuse in the pediatric setting. Deimplementation of disproven practices and careful examination of emerging practices are imperative to prevent unnecessary resource use and patient harm.

Physiological indicators of pathologic video game use in adolescence.

PURPOSE: Pathologic video game use (PVGU) has been associated with a host of negative psychological, physical, and social outcomes during adolescence; however, little research has examined physiological predictors of such use. The purpose of the study was to examine physiological predictors of the development of PVGU across adolescence. METHODS: The article involves a 1-year longitudinal study across midadolescence. Participants were 374 adolescents and their parents from a large metropolitan area in the Northwest United States. PVGU was assessed via questionnaire, as were a number of control variables. A number of physiological indicators including respiratory sinus arrhythmia (RSA) and galvanic skin conductance (indices of parasympathetic and sympathetic nervous system activity, respectively) were measured during baseline, a cognitively stimulating task (Rubik's cube), and a family problem-solving task. RESULTS: Less RSA withdrawal to a cognitively simulating task was related to greater pathologic video game symptoms, but less RSA withdrawal to a family problem-solving task was associated with the presence of pathologic video game symptoms (p < .05). For girls only, galvanic skin conductance activation during the family problem solving was related to greater pathologic video game symptoms (p < .01). CONCLUSIONS: These findings suggest that adolescents who do not find cognitive tasks stimulating physiologically have a greater severity of PVGU. Additionally, adolescents who show physiological signs of stress in a family task were more likely to have PVGU symptoms and only girls have more severe PVGU levels. This study is the first to show that physiological indicators predict PVGU over time in adolescence and has important implications regarding the prevention and treatment of PVGU in adolescence.
