Objectives: This study aimed to determine if the presence of a pericardial effusion is associated with adverse outcomes among children admitted with juvenile idiopathic arthritis. Patients and methods: The multicenter, retrospective cohort study was conducted with 4,332 patients (1,554 males, 2,778 females; median age: 12 years; IQR, 7, 15 years) using the Pediatric Health Information System. Data from hospital admissions between January 1, 2004, and September 15, 2015, were obtained for patients with an International Disease Classification, Ninth Revision code for juvenile idiopathic arthritis. Pericardial effusion was the primary predictor variable; the outcomes of interest were length of stay, hospital costs, and readmission within 90 days. Multivariate models were created to evaluate associations between pericardial effusion and adverse outcomes. We also analyzed factors associated with increased odds of having pericardial effusion in juvenile idiopathic arthritis. Results: One hundred twenty (3%) patients had a code for pericardial effusion. Children with pericardial effusion had a longer median length of stay (7 days (IQR 3-12) vs. 3 days (IQR 2-6), p<0.001), higher median costs ($17,688 (IQR 8,657-40,623) vs. $8,456 (IQR 4,865-16,302), p<0.001), and greater rates of readmission (22% vs. 15%, p=0.045). Multivariate analysis demonstrated no significant association between pericardial effusion and outcomes of interest. Black race and male sex were associated with increased odds of having pericardial effusion. Conclusion: Pericardial effusion is rare among children admitted with juvenile idiopathic arthritis but is associated with significant morbidity; its presence may be a marker of disease severity. Black children and males admitted with juvenile idiopathic arthritis warrant special consideration and may benefit from screening echocardiography. [ABSTRACT FROM AUTHOR]

Objective: Multiple reports have shown echocardiograms for certain indications are neither cost-effective nor of high diagnostic yield. Given the ease with which tests can be obtained at a tertiary academic children's hospital, our aims were to: (1) determine the diagnostic yield of inpatient studies by in-hospital location; (2) evaluate inpatient echocardiograms to determine indications and level of appropriateness; and (3) evaluate the frequency of cardiology involvement prior to those echocardiograms., Design: All initial inpatient echocardiograms interpreted at our institution from February 2009 to December 2014 were reviewed retrospectively. Patient location was grouped as pediatric intensive care (PICU), emergency department (ED), and general floor., Results: There were 727 first-time inpatient echocardiograms that met inclusion criteria. Pathology was identified in 25% of the study echocardiograms, with 11% of all studies demonstrating pathology that could alter patient management (moderate or severe pathology). The studies performed in the PICU and ED had more severe pathology compared with those from the general floor (P < .001, .003; respectively). Few echocardiograms were performed for rarely appropriate indications on the general floor (7%) and PICU (2.2%). Over 75% of general floor echocardiograms performed for a pathologic murmur yielded normal or incidental findings. Cardiology consultation was documented in only 7.5% of general floor studies., Conclusion: The diagnostic yield of inpatient, first-time pediatric echocardiograms is relatively low. The majority of studies that identified pathology were performed on patients located in higher acuity units. General floor echocardiograms for murmurs had a low diagnostic yield, raising the question of cardiology consultation versus direct echocardiogram ordering for subjective physical exam signs., (© 2016 Wiley Periodicals, Inc.)
