Decreasing Overutilization of Echocardiograms and Abdominal Imaging in the Evaluation of Children with Fungemia

Objective: Pediatric fungemia is associated with a low risk of fungal endocarditis and renal infections. The majority of current guidelines do not recommend routine abdominal imaging/echocardiograms in the evaluation of fungemia, but such imaging has been routinely ordered for patients on the pediatric gastroenterology service at our institution. Our goals were to assess the financial impact of this deviation from current clinical guidelines and redefine the standard work to reduce overutilization of abdominal ultrasounds and echocardiograms. Specifically, our goal was to reduce imaging by 50% by 18 months. Methods: Root cause analysis showed a lack of familiarity with current evidence. Using this data, countermeasures were implemented, including practitioner education of guidelines and creation of a readily accessible clinical pathway and an electronic order set for pediatric fungemia management. Balancing measures were missed episodes of fungal endocarditis and renal infection. Results: During the period January 1, 2016 to November 19, 2017, 18 of 21 episodes of fungemia in our pediatric institution occurred in patients admitted to the pediatric gastroenterology service. Abdominal imaging and echocardiograms were done 100% of the time, with no positive findings and an estimated cost of approximately $58,000. Post-intervention from November 20, 2017 to April 3, 2019, 7 of 13 episodes of fungemia occurred on this service. Frequency of abdominal imaging and echocardiograms decreased to 43% and 57%, respectively. No episodes of fungal endocarditis or renal infection were identified. Conclusion: Overutilization of abdominal imaging and echocardiograms in pediatric fungemia evaluation can be safely decreased

Transient liver elastography in unsedated control children: Impact of age and intercurrent illness

Transient elastography (TE) is a rapid, non-invasive, reproducible assessment of liver fibrosis by liver stiffness measurement (LSM). Uncertainty remains regarding utility in children, unsedated an

Accuracy of transient elastography data combined with APRI in detection and staging of liver disease in pediatric patients with cystic fibrosis

Liver disease develops in 15%-72% of patients with cystic fibrosis, and 5%-10% develop cirrhosis or portal hypertension, usually during childhood. Transient elastography (TE) is a noninvasive method to measure liver stiffness. We aimed to validate its accuracy in detection of liver disease and assessment of fibrosis in children with cystic fibrosis.We performed a cross-sectional study to evaluate the accuracy of TE in analysis of liver fibrosis in 160 consecutive children who presented with cystic fibrosis (9.0±0.4 years old, 53% male) at a tertiary referral pediatric center in Australia, from 2011 through 2016. Patients were classified as having cystic fibrosis-associated liver disease (CFLD) or cystic fibrosis without liver disease (CFnoLD) based on clinical, biochemical, and imaging features. Fibrosis severity was determined from histologic analysis of dual-pass liver biopsies from children with CFLD, as the reference standard. Data from healthy children without cystic fibrosis (n=64, controls) were obtained from a separate study. Liver stiffness measurements (LSMs) were made by Fibroscan analysis, using the inter-quartile range/median ≤30% of 10 valid measurements. Children with macronodularity or portal hypertension with heterogeneous changes on ultrasound without available biopsy were assigned to the category of stage F3-F4 fibrosis.LSM was made reliably in 86% of children; accuracy increased with age. LSMs were significantly higher in children with CFLD (10.7±2.4 kPa, n=33) than with CFnoLD (4.6±0.1 kPa, n=105) (
