Antimicrobial stewardship programs seek to improve patient outcomes, reduce cost, and hinder development of antimicrobial resistance. Collection of inpatient antimicrobial use data is foundational to these programs, and decisions to initiate and discontinue antibiotics are potentially amenable to improvement. In order to better understand our current practices and with a view toward improved antimicrobial stewardship, we reviewed charts of previously healthy children to age 16 years hospitalized with fever (without an evident localized source) and/or other findings suggestive of serious bacterial infection. Of 105 patients (18% 0-2 months of age, 42% 3-12 months, 25% 2-5 years), 100 (95%) received antibiotics, 72% for more than 2 days. Of 98 patients with negative body fluid cultures, 23 received antibiotics for 2 days or less, and 70 received antimicrobial therapy for more than 2 days. Focusing on selective initiation and earlier discontinuation of antimicrobial therapy in hospitalized children might reduce unnecessary antibiotic use.

AbstractBackgroundThe functional lumen imaging probe (FLIP) evaluates esophagogastric junction (EGJ) opening and esophageal contractility. Both post hoc and real‐time analyses are possible, but reproducibility and reliability of analysis remain undefined. This study assesses inter‐ and intra‐rater agreement of normative FLIP measurements among novice and experienced users.MethodsEight motility experts from different institutions independently evaluated de‐identified video recordings from 27 asymptomatic healthy subjects using FLIP. Interpretation methods simulating a post‐procedure and a live procedure setting were tested. Novice FLIP users (n = 3) received training prior to post‐procedure interpretation. Experienced FLIP users (n = 5) interpreted using both methods. Users recorded maximum EGJ and distal esophageal body diameter, distensive pressure, and EGJ distensibility index (EGJ‐DI), at balloon fill volumes of 50‐, 60‐, and 70 ml, as well as repetitive antegrade contractions (RACs). Inter‐ and intra‐rater agreements of diameters, distensive pressure and EGJ‐DI were assessed by intra‐class correlation coefficient (ICC) and Pearson's correlation coefficient (PCC). Percentage agreement evaluated inter‐ and intra‐rater reliability for RACs.Key ResultsNovice and experienced users acquired normative FLIP metrics. Good‐to‐excellent inter‐ and intra‐rater reliability were achieved for all variables at 60 ml balloon fill volumes. Median parameters at 60 ml balloon fill volume were as follows: EGJ‐DI 5.5 mm2/mmHg, maximum EGJ diameter 18.6 mm, distensive pressure at maximum EGJ diameter 48.1 mmHg, and distal esophageal body diameter 19.5 mm.Conclusions and InferencesNormative FLIP parameters can be reliably extracted from FLIP videos using both real‐time and post hoc analyses, with high reliability between experienced and novice users.

ImportanceLate-onset meningitis (LOM) has been associated with adverse neurodevelopmental outcomes in children born extremely preterm.ObjectiveTo report the incidence of LOM during birth hospitalization and neurodevelopmental outcomes at 18 to 26 months’ corrected age.Design, Setting, and ParticipantsThis cohort study is a secondary analysis of a multicenter prospective cohort of children born at 22 to 26 weeks’ gestation between 2003 and 2017 with follow-up from 2004 to 2021. The study was conducted at 25 Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network centers.ExposuresCulture-confirmed LOM.Main Outcomes and MeasuresIncidence and microbiology of LOM (2003-2017); lumbar puncture (LP) performance in late-onset sepsis (LOS) evaluations (2011-2017); composite outcome of death or neurodevelopmental impairment (NDI; 2004-2021).ResultsAmong 13 372 infants (median [IQR] gestational age, 25.4 [24.4-26.1] weeks; 6864 [51%] boys), LOM was diagnosed in 167 (1%); LOS without LOM in 4564 (34%); and neither LOS nor LOM in 8641 (65%). The observed incidence of LOM decreased from 2% (95% CI, 1%-3%) in 2003 to 0.4% (95% CI, 0.7%-1.0%) in 2017 (P < .001). LP performance in LOS evaluations decreased from 36% (95% CI, 33%-40%) in 2011 to 24% (95% CI, 21%-27%) in 2017 (P < .001). Among infants with culture-confirmed LOS, LP performance decreased from 58% (95% CI, 51%-65%) to 45% (95% CI, 38%-51%; P = .008). LP performance varied by center among all LOS evaluations (10%-59%, P < .001) and among those with culture-confirmed LOS (23%-79%, P < .001). LOM occurred in the absence of concurrent LOS in 27 of 167 cases (16%). The most common LOM isolates were coagulase-negative Staphylococcus (98 [59%]), Candida albicans (38 [23%]), and Escherichia coli (27 [16%]). Death or NDI occurred in 22 of 46 children (48%) with LOM due to coagulase-negative Staphylococcus, 43 of 67 (64%) due to all other bacterial pathogens, and 26 of 33 (79%) due to fungal pathogens. The adjusted relative risk of death or NDI was increased among children with LOM (aOR, 1.53; 95% CI, 1.04-2.25) and among those with LOS without LOM (aOR, 1.41; 95% CI, 1.29-1.54) compared with children with neither infection.Conclusions and RelevanceIn this cohort study, LP was performed with decreasing frequency, and the observed incidence of LOM also decreased. Both LOM and LOS were associated with increased risk of death or NDI; risk varied by LOM pathogen. The full association of LOM with outcomes of children born extremely preterm may be underestimated by current diagnostic practices.
