Infants with heart disease are at high risk of feeding difficulties and complications. Feeding practices amongst acute care cardiology units are not standardized. This study aims to describe feeding practices for infants at the time of discharge from a Pediatric Acute Care Cardiology Collaborative (PAC 3 ) center and practice variation between centers. Discharge encounters for infants in the PAC 3 registry between February 2019 and October 2021 were included. Nutrition type and feeding route at discharge were summarized with descriptive statistics and a modified bump plot. Center variation was assessed using funnel plots with control limits set at the 99.9% confidence interval from the group mean. A total of 15,414 encounters across 24 PAC 3 centers were recorded from 8313 unique patients (median encounters 1, range 1-25). Nutrition at discharge consisted of standard formula in 8368 (54%), human milk in 6300 (41%), and elemental formula in 3230 (21%), either alone or in combination. Feeds were fortified to ≥ 24 kcal/oz in 12,359 (80%). Discharge supplemental tube feeding was present in 7353 (48%) encounters with 4643 (63%) receiving continuous feeds, 2144 (29%) bolus feeds, and 566 (8%) a combination. Funnel plots demonstrated variability in nutrition type and feeding route at discharge. Infants with heart disease commonly require high calorie nutrition and supplemental tube feedings at discharge. Feeding strategies at discharge vary widely between PAC 3 centers. Collaborative approaches to identify best practices in feeding strategies are needed., (© 2024.

Our aim was to reduce the frequency of unnecessary testing used by pediatric cardiologists in the evaluation of pediatric patients with syncope or pre-syncopal symptoms without negatively affecting patient outcomes. Guidelines for cardiac testing in pediatric patients with syncope were developed and disseminated to members of our pediatric cardiology division. Educational brochures and water bottles labeled with tips on preventing syncope were made available to families and providers in our clinics. Compliance to the guidelines was tracked and shared with providers. Segmented regression analysis was used to model cardiac testing utilization and guideline compliance by provider over time before and after the implementation of the guidelines. A pre-intervention cohort of 237 patients (June 2014-May 2015) was compared to 880 post-intervention patients (August 2015-June 2019). There was a significant decrease in the utilization of unnecessary tests [odds ratio (OR) 0.3; 95% confidence interval (CI) 0.14, 0.65; p = 0.002] after the intervention. Charges associated with patient evaluation were significantly lower in the post-intervention cohort (interquartile range $0, $1378 vs $0, $213; p = 0.005). Post-intervention visits to emergency departments within our system were significantly decreased, with no change in the incidence of cardiac arrest, hospitalization for syncope, or referral to pediatric electrophysiologists. We demonstrated a significant reduction in the use of unnecessary testing and associated charges by developing guidelines related to the evaluation of pediatric patients with syncope or pre-syncopal symptoms. There was no demonstrable negative impact on patient outcomes.

Background: Coronary artery abnormalities in Kawasaki disease (KD) are assessed using echocardiographic z-scores. We hypothesized that changing the coronary artery (CA) z-score model would alter diagnosis and management of children with KD., Methods: In this retrospective single-center study of children treated for KD (9/2007-1/2020), we collected echocardiographic measurements for the left anterior descending (LAD), right (RCA), and left main (LMCA) coronary arteries during 3 illness phases and calculated Boston and Pediatric Heart Network (PHN) z-scores. Agreement between Boston and PHN z-scores was assessed using Kappa (κ) and Lin's Concordance Correlation Coefficients (CCC) and Bland-Altman analysis., Results: For 904 echocardiograms from 357 children, the median Boston LAD z-score was lower than the PHN (0.3 [IQR - 0.6, 1.5] vs 1.6 [IQR 0.7, 2.8], CCC 0.94 [95% CI 0.93, 0.95], moderate agreement), aggregated across all illness phases. RCA and LMCA z-scores showed substantial agreement. With conversion from Boston to PHN models, the percentage of individual LAD z-scores ≥ 2.5 increased (14.6% to 32.1%). At least one CA z-score classification changed in 213 children (59.7%) across all phases, and 48 children (13.4%) had a change that altered recommended antithrombotic strategy. Agreement between models differed by age, sex, and race., Conclusions: Conversion from Boston to PHN z-scores changed at least 1 CA z-score classification in over half of KD patients and changed recommended antithrombotic management in 13%, largely driven by LAD measurements. Since diagnosis and management of KD and KD-like diseases rely upon CA z-scores, the clinical and research implications of these findings merit further exploration.

Children with acquired and congenital heart disease (CHD) are increasingly surviving to adulthood. Our aim was to determine the prevalence of coronary artery disease (CAD) risk factors in children at known risk for early CAD or with severe CHD. We recruited children (8-19 years) at risk for early CAD-Kawasaki disease (KD, N = 36) and coarctation (69) or severe CHD: > 1 cardiopulmonary bypass surgery (60), single ventricle (15), prosthetic valves (13). Anthropometric measurements, blood pressure, and fasting lipid data were compared with summaries from National Health and Nutrition Examination Survey (NHANES) publications (1999-2012). Relative risk (RR) ratios were calculated based on age classification and pooled to obtain overall RR. Of 174 subjects, 106 were male (61%) and 138 (79%) had CHD. Compared to NHANES data, hypertension and low HDL were higher in the study cohort [RR 11.7 (CI 6.34-21.6), p < 0.001; and 1.79 (CI 1.36-2.35). p < 0.001] and obesity and elevated total cholesterol were lower [RR 0.59 (CI 0.37-0.96), p = 0.03; and 0.42 (CI 0.19-0.95), p = 0.04]. Elevated non-HDL was similar between groups. Age category had similar RR for all CAD risk factors. Eight subjects had metabolic syndrome. Risk factors were similar between KD versus CHD subgroups. Both coarctation and non-coarctation subjects had increased RR for hypertension. Hypertension is the most common risk factor for children at risk of early CAD and severe CHD. Metabolic syndrome is rare. These patients should be screened and treated for hypertension and current recommendations for universal lipid screening are adequate for follow-up.
