Abstract

Serum troponin (Tn) is often elevated in viral myocarditis; however, its prognostic significance is unknown. We tested the hypothesis that abnormal serum Tn is associated with mortality in children hospitalized with myocarditis. We retrospectively studied data from six large children's hospitals participating in the Pediatric Health Information System Plus (PHIS+) database. Analysis was performed on patients hospitalized with viral myocarditis between 2007 and 2013, in whom at least one Tn was recorded within 72 h of admission. Abnormal baseline Tn was defined as any value outside the upper limit of normal within the first 72 h. Primary outcome was mortality. Secondary outcomes included mechanical support, defined as use of extracorporeal membrane oxygenation (ECMO) or a ventricular assist device (VAD), cardiac transplantation, intravenous immunoglobulin (IVIg), mechanical ventilation, and inotrope use. A total of 149 patients with myocarditis (61% male, 48% adolescents) across all PHIS+ centers had TnI (n = 113) or TnT (n = 36) recorded. At least one abnormal Tn was present in 81% of cases. Overall mortality was 7.3% and was not associated with abnormal baseline Tn. Abnormal baseline Tn was associated with ECMO (7.1 vs. 25.6%, p = 0.03) and IVIg (46.4 vs. 83.5%, p < 0.001). Abnormal baseline Tn was not associated with transplantation, mechanical ventilation or inotrope use. Abnormal Tn in the first 72 h of hospitalization for myocarditis was associated with the use of ECMO and IVIg, but was not associated with mortality. This finding may help risk stratify this population if it can be prospectively validated.

Abstract

<p><strong>OBJECTIVE: </strong>There are scarce data about the prevalence and mortality of necrotizing enterocolitis in neonates with congenital heart disease. The purpose of this study is to provide a multi-institutional description and comparison of the overall prevalence and mortality of necrotizing enterocolitis in neonates with congenital heart disease.</p>

<p><strong>DESIGN: </strong>Retrospective multi-institutional study.</p>

<p><strong>SETTING: </strong>The Pediatric Health Information System database.</p>

<p><strong>PATIENTS: </strong>Neonates with congenital heart disease between 2004 and 2014.</p>

<p><strong>INTERVENTIONS: </strong>None.</p>

<p><strong>MEASUREMENTS AND MAIN RESULTS: </strong>The primary study measure is the prevalence of necrotizing enterocolitis. Secondary measures include in-hospital mortality, hospital charges, ICU length of stay, hospital length of stay, and 30-day readmission. The prevalence of necrotizing enterocolitis was 3.7% (1,448/38,770) and varied significantly among different congenital heart disease diagnoses. The lowest prevalence of necrotizing enterocolitis was in transposition of the great arteries (n = 104, 2.1%). Compared with transposition of the great arteries, necrotizing enterocolitis occurred more frequently in neonates with hypoplastic left heart syndrome (odds ratio, 2.7; 95% CI, 2.1-3.3), truncus arteriosus (odds ratio, 2.6; 95% CI, 1.9-3.5), common ventricle (odds ratio, 2.1; 95% CI, 1.5-2.8), and aortic arch obstruction (odds ratio, 1.4; 95% CI, 1.1-1.7). Prematurity is a significant risk factor for necrotizing enterocolitis and for mortality in neonates with necrotizing enterocolitis, conferring varying risk by cardiac diagnosis. Unadjusted mortality associated with necrotizing enterocolitis was 24.4% (vs 11.8% in neonates without necrotizing enterocolitis; p &lt; 0.001), and necrotizing enterocolitis increased the adjusted mortality in neonates with transposition of the great arteries (odds ratio, 2.5; 95% CI, 1.5-4.4), aortic arch obstruction (odds ratio, 1.8; 95% CI, 1.3-2.6), and tetralogy of Fallot (odds ratio, 1.6; 95% CI, 1.1-2.4). Necrotizing enterocolitis was associated with increased hospital charges (p &lt; 0.0001), ICU length of stay (p = 0.001), and length of stay (p = 0.001).</p>

<p><strong>CONCLUSIONS: </strong>The prevalence of necrotizing enterocolitis among neonates with congenital heart disease is 3.7% and is associated with increased in-hospital mortality, length of stay, and hospital charges. The prevalence and associated mortality of necrotizing enterocolitis in congenital heart disease vary among different heart defects.</p>

Abstract

<p>Little research attention has been paid to the occurrence of heart failure (HF) in children with complex congenital heart diseases (CHDs). Herein, we describe the prevalence, risk factors, and costs associated with HF in complex CHD. Patients aged&nbsp;≤17&nbsp;years and diagnosed with a complex CHD on multiple service visits over a 15-year period in the SC Medicaid dataset (1996-2010) were tracked and analyzed. The cohort included 2999 unduplicated patients; 51.0% were male; 34.4% were African American. HF was diagnosed in 7.6%. Single ventricle lesions, genetic syndromes, and ventricular arrhythmia were significantly associated with an increased likelihood of being diagnosed with HF, controlling for development of comorbid pulmonary hypertension. Patients with HF received significantly more subspecialty care, more surgeries, more hospitalizations, more total days of inpatient care, and more emergency department care than those without HF. Patients with significantly higher total care costs paid by Medicaid had HF, more cardiac surgeries, and more specialized mechanical or other support procedures, controlling for diagnosed single ventricle CHD, a genetic syndrome, and number of non-cardiac surgeries. Complex CHD patients with HF incur significantly higher care costs but require multifaceted, intensive supports for management of incident complications and comorbid conditions.</p>

Abstract

<p><strong>BACKGROUND: </strong>Continuous-flow ventricular assist devices (CF VADs) designed for adults are increasingly used in pediatric patients. However, there is greater risk of device inflow obstruction as a result of size and anatomy.</p>

<p><strong>METHODS: </strong>We reviewed all cases of systemic atrioventricular valve (AVV) excision with HeartWare HVAD (HeartWare, Framingham, MA) implantation in the systemic ventricle performed at our institution from November 2015 to May&nbsp;2016.</p>

<p><strong>RESULTS: </strong>AVV excision with CF VAD implantation was undertaken in 3 patients. Patient 1 was palliated in infancy, resulting in biventricular physiology with a systemic right ventricle, and presented at age 15 years with worsening ventricular dysfunction. After CF VAD implantation in the systemic ventricle and discharge to home, tricuspid valve obstruction to VAD inflow developed, and the patient and underwent tricuspid valve excision on postoperative day 52. Patients 2 and 3 were aged younger than 4 years, with a body surface area of 0.62 m(2) and 0.58 m(2), respectively, and had undergone Fontan palliation, with subsequent systemic ventricular dysfunction and AVV regurgitation. In both Fontan patients, the CF VAD was implanted in the right atrium with simultaneous excision of the AVV. None have had evidence of elevated atrial pressures or recalcitrant pulmonary edema. At a mean follow-up of 359 days (range, 304 to 422 days), there have been no concerns for inflow obstruction or low flow.</p>

<p><strong>CONCLUSIONS: </strong>CF VAD implantation with AVV excision can successfully support complex pediatric patients in a wide range of size and anatomy (small chambers, systemic right ventricles). This technique may allow for CF VAD implantation in patients previously deemed too small for such support.</p>

Abstract

<p>Scarce data exist regarding costs of pediatric heart failure-related hospitalizations (HFRH) or how costs have changed over time. Pediatric HFRH costs, due to advances in management, will have increased significantly over time. A retrospective analysis of Healthcare Cost and Utilization Project Kids' Inpatient Database was performed on all pediatric HFRH. Inflation-adjusted charges are used as a proxy for cost. There were a total of 33,189 HFRH captured from 2000 to 2009. Median charges per HFRH rose from $35,079 in 2000 to $72,087 in 2009 (p &lt; 0.0001). The greatest median charges were incurred in patients on extracorporeal membrane oxygenation ($442,134 vs $53,998) or ventricular assist devices ($462,647 vs $55,151). Comorbidities, including sepsis ($207,511 vs $48,995), renal failure ($180,624 vs $52,812), stroke ($198,260 vs $54,974) and respiratory failure ($146,200 vs $48,797), were associated with greater charges (p &lt; 0.0001). Comorbidities and use of mechanical support increased over time. After adjusting for these factors, later year remained associated with greater median charges per HFRH (p &lt; 0.0001). From 2000 to 2009, there has been an almost twofold increase in pediatric HFRH charges, after adjustment for inflation. Although comorbidities and use of mechanical support account for some of this increase, later year remained independently associated with greater charges. Further study is needed to understand potential factors driving these higher costs over time and to identify more cost-effective therapies in this population.</p>

Abstract

<p>Heart failure in children is a complex disease process, which can occur secondary to a variety of aetiologies, including CHD, cardiomyopathy, or acquired conditions as well. Although the overall incidence of disease is low, the associated morbidity and mortality are high. Mortality may have decreased slightly over the last decade, and this is likely due to our ability to shepherd patients through longer periods of significant morbidity, with lasting effects. Costs of heart failure are significant - on the order of $1 billion annually as hospital charges for inpatient admissions alone. The value, or benefit to patient life and quality of life at this cost, is not well delineated. Further research is needed to optimise not only outcomes for these patients but also the high costs associated with them.</p>

Abstract

<p><strong>OBJECTIVE: </strong>To evaluate the impact of a pediatric emergency department (ED) chest pain clinical pathway on resource utilization.</p>

<p><strong>METHODS: </strong>Motivated by perceived overuse of cardiology consultation for non-cardiac chest pain in the ED, clinicians from the Divisions of Cardiology and Emergency Medicine collaboratively developed a chest pain clinical pathway, educated staff, and implemented the pathway on March 1, 2014. We reviewed records of children aged 3 to 18 years without prior diagnoses of heart disease who presented to the ED with chest pain between March 1, 2013, and April 22, 2015. We compared diagnostic testing rates, ED length of stay, and cardiology consults before and after implementation of the pathway.</p>

<p><strong>RESULTS: </strong>A total of 1687 patients were pathway eligible (675 patients preimplementation and 1012 postimplementation). Resource utilization was lower than expected before pathway implementation and remained low after implementation. There was a statistically significant reduction in rates of chest x-ray ordering after pathway implementation and ED length of stay but no change in other diagnostic testing or cardiology consultation. Follow-up in our health care system for pediatric chest pain increased from 15% to 29% with implementation, but none of these visits resulted in the diagnosis of a new cardiac condition. There were no instances identified where use of the pathway resulted in missed cardiac disease.</p>

<p><strong>CONCLUSIONS: </strong>Implementation of a clinical pathway for pediatric chest pain did lead to a reduction in chest x-ray ordering in the ED and was associated with a higher rate of outpatient follow up for non-pathologic chest pain. Preimplementation utilization was lower than the prepathway perceptions of overuse suggested.</p>
