Abstract
BACKGROUND: Pediatric heart transplantation (HT) is resource intensive. In adults, there has been an increase in the proportion of HTs funded by public insurance, with post-HT outcomes inferior to those funded by private sources. Trends in the funding of pediatric HT and outcomes in children have not been described.
METHODS: We queried the United Network for Organ Sharing (UNOS) database for children (<18 years) listed for and undergoing HT between 2004 and 2021. We identified the primary payer at listing, HT, 1 year, and 1-5 years following HT. Trends were analyzed using generalized logit models. Multivariable-extended Cox regression models were used to test the relationship between insurance type at the time of transplant and time to death or re-transplant.
RESULTS: There were 6382 pediatric patients who underwent transplants and had either public or private insurance at the time of transplant. The percentage of patients with public insurance at the time of HT increased over time. Public insurance at the time of HT was associated with an increased risk of death or re-transplant beyond 2 months after HT (adjusted HR at 6 months = 1.43, 95% CI: 1.13-1.81, p = .003; adjusted HR at 9 months = 1.67, 95% CI: 1.17-2.37, p = .004).
CONCLUSION: There has been a statistically significant trend toward increasing public insurance for children awaiting, at the time of, and after HT. Black patients and those with public insurance at HT have worse long-term outcomes. This study highlights ongoing disparities in pediatric HT and the need to focus efforts on achieving equitable outcomes.

Abstract
OBJECTIVE: To assess the relationship between posthospitalization prescription fills for recommended asthma discharge medication classes and subsequent hospital readmission.
STUDY DESIGN: This was a retrospective cohort analysis of Medicaid Analytic Extract files from 12 geographically diverse states from 2005-2007. We linked inpatient hospitalization, outpatient, and prescription claims records for children ages 2-18 years with an index hospitalization for asthma to identify those who filled a short-acting beta agonist, oral corticosteroid, or inhaled corticosteroid within 3 days of discharge. We used a multivariable extended Cox model to investigate the association of recommended medication fills and hospital readmission within 90 days.
RESULTS: Of 31,658 children hospitalized, 55% filled a beta agonist prescription, 57% an oral steroid, and 37% an inhaled steroid. Readmission occurred for 1.3% of patients by 14 days and 6.3% by 90 days. Adjusting for patient and billing provider factors, beta agonist (hazard ratio [HR] 0.67, 95% CI 0.51, 0.87) and inhaled steroid (HR 0.59, 95% CI 0.42, 0.85) fill were associated with a reduction in readmission at 14 days. Between 15 and 90 days, inhaled steroid fill was associated with decreased readmission (HR 0.87, 95% CI 0.77, 0.98). Patients who filled all 3 medications had the lowest readmission hazard within both intervals.
CONCLUSIONS: Filling of beta agonists and inhaled steroids was associated with diminished hazard of early readmission. For inhaled steroids, this effect persisted up to 90 days. Efforts to improve discharge care for asthma should include enhancing recommended discharge medication fill rates.

Abstract
OBJECTIVES: Controversy exists in ascertaining the ideal location for adults with congenital heart disease requiring surgical intervention. In this study, we sought to compare the perioperative management between our paediatric and adult hospitals and to determine how clinical factors and the location affect the length of stay after pulmonary valve replacement.
METHODS: A retrospective analysis of patients, ≥18 years of age, undergoing pulmonary valve replacement was conducted at our paediatric and adult hospitals between 1 January 2000 and 30 October 2014. Patients with previous Ross or concomitant left heart procedures were excluded. Descriptive statistics were used to assess demographics and clinical characteristics. Inverse probability weight-adjusted models were used to determine differences in the number of surgical complications, duration of mechanical ventilation and postoperative length of stay between paediatric and adult hospitals. Additional models were calculated to identify factors associated with prolonged length of stay.
RESULTS: There were altogether 98 patients in the adult (48 patients) and paediatric (50 patients) hospitals. Patients in the adult hospital were older with more comorbidities (arrhythmia, hypertension, depression and a history of cardiac arrest, all P < 0.05). Those at the paediatric hospital had better preoperative right ventricular function and less tricuspid regurgitation. The cardiopulmonary bypass time, the length of intubation and the length of stay were higher at the adult hospital, despite no difference in the number of complications between locations. Factors contributing to the increased length of stay include patient characteristics and postoperative management strategies. There were no deaths.
CONCLUSIONS: Pulmonary valve replacement may be performed safely with no deaths and with a comparable complication rate at both hospitals. Patients undergoing surgery at the adult hospital have longer intubation times and length of stay. Opportunities exist to streamline management strategies.

Abstract
BACKGROUND: There is ongoing debate about the best strategy to treat patients with tetralogy of Fallot who are symptomatic in the neonatal period.
OBJECTIVES: The aim of this study was to compare the outcomes of complete versus staged surgery (i.e., initial palliative procedure for possible later complete repair).
METHODS: A retrospective cohort study was performed using the Pediatric Health Information System database, including patients who underwent complete or staged tetralogy of Fallot repair prior to 30 days of age. The primary outcome was death during 2-year follow-up after the initial procedure. Inverse probability-weighted Cox and logistic regression models were used to examine the association between surgical approach group and mortality while accounting for patient- and hospital-level factors. Causal mediation analyses examined the role of intermediate variables.
RESULTS: A total of 2,363 patients were included (1,032 complete and 1,331 staged). There were 239 deaths. Complete neonatal repair was associated with a significantly higher risk for mortality during the 2-year follow-up period (hazard ratio: 1.51; 95% confidence interval: 1.05 to 2.06), between 7 and 30 days after the initial procedure (hazard ratio: 2.29; 95% confidence interval: 1.18 to 4.41), and during the initial hospital admission (odds ratio: 1.72; 95% confidence interval: 1.15 to 2.62). Post-operative cardiac complications were more common in the complete repair group and mediated the differences in 30-day and 2-year mortality.
CONCLUSIONS: Complete surgical repair for neonates with tetralogy of Fallot is associated with a significantly higher risk for early and 2-year mortality compared with the staged approach, after accounting for patient and hospital characteristics. Post-operative cardiac complications mediated these findings.

Abstract
<p><strong>Background</strong> Universal lipid screening in children provides an opportunity to mitigate the lifetime risk of atherosclerosis, particularly in children with chronic conditions that are predisposed to early atherosclerosis. In response, national guidelines recommend additional early screening in a subset of cardiac conditions. The penetration of such guidelines has not been evaluated. <strong>Methods and Results</strong> We performed a retrospective study of a geographically representative sample of US children using the MarketScan Commercial and Medicaid claims databases. The study population was children with cardiac disease between ages 2 and 18 years and ≥3 years of continuous coverage from January 1, 2013, to June 30, 2018, divided into 4 major strata of heart disease. We assessed the likelihood of screening between these classifications and compared with healthy children and calculated multivariate models to identify patient factors associated with screening likelihood. Of the eligible 8.4 million children, 155 000 children had heart disease, of which 1.8% (31 216) had high-risk conditions. Only 17.5% of healthy children underwent lipid screening. High-risk children were more likely to be screened (odds ratio [OR], 2.1; 95% CI, 2.09-2.19; <0.001) than standard-risk children, but that likelihood varied depending on strata of cardiac disease (22%-77%). Timing of screening also varied, with most occurring between ages 9 and 11 years. Among cardiac conditions, heart transplantation (OR, 16.8; 95% CI, 14.4-19.7) and cardiomyopathy (OR, 2.9; 95% CI, 2.8-3.1) were associated with the highest likelihood of screening. <strong>Conclusions</strong> Children with cardiac disease are more likely to undergo recommended lipid screening than healthy children, but at lower rates and later ages than recommended, highlighting the importance of quality improvement and advocacy for this vulnerable population.</p>

Abstract
<p><strong>BACKGROUND: </strong>Survivors of Fontan palliation are at life-long risk of thrombosis, arrhythmia, and circulatory failure. To our knowledge, no studies have evaluated current United States pharmaceutical prescription practice in this population.</p>
<p><strong>METHODS: </strong>A retrospective observational study evaluating the prevalent use of prescription medications in children and adolescents with hypoplastic left heart syndrome or tricuspid atresia after Fontan completion (identified using ICD9/10 codes) was performed using data contained in the MarketScan® Commercial and Medicaid databases for the years 2013 through 2018. Cardiac pharmaceuticals were divided by class. Anticoagulant agents other than platelet inhibitors, which are not uniformly a prescription medication, were also studied. Associations between increasing age and the likelihood of a filled prescription for each class of drug were evaluated. Annualized retail costs of pharmaceutical regimens were calculated.</p>
<p><strong>RESULTS: </strong>A cohort of 4056 subjects [median age 12 years (IQR: 8-16), 61% male, 60% commercial insurance] was identified. Of the cohort, 50% received no prescription medications. Angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARB) (38%), diuretics (15%), and mineralocorticoid receptor antagonists (8%) were prescribed with the highest frequency. Pulmonary vasodilators were received by 6% of subjects. Older age was associated with increased likelihood of filled prescriptions for anticoagulants (p=0.008), antiarrhythmic agents, digoxin, ACEi/ARB, and beta blockers (each p<0.0001), but also lower likelihood of filled prescriptions for pulmonary vasodilators, conventional diuretics (both p<0.0001), and mineralocorticoid receptor antagonists (p=0.02).</p>
<p><strong>CONCLUSION: </strong>Pharmaceuticals typically used to treat heart failure and pulmonary hypertension are the most commonly prescribed medications following Fontan palliation. While the likelihood of treatment with a particular class of medication is associated with the age of the patient, determining the optimal regimen for individual patients and the population at large is an important knowledge gap for future research.</p>

Abstract
<p>Tetralogy of Fallot (TOF) repair is associated with excellent operative survival. However, a subset of patients experiences post-operative complications, which can significantly alter the early and late post-operative course. We utilized a machine learning approach to identify risk factors for post-operative complications after TOF repair. We conducted a single-center prospective cohort study of children <2 years of age with TOF undergoing surgical repair. The outcome was occurrence of post-operative cardiac complications, measured between TOF repair and hospital discharge or death. Predictors included patient, operative, and echocardiographic variables, including pre-operative right ventricular strain and fractional area change as measures of right ventricular function. Gradient-boosted quantile regression models (GBM) determined predictors of post-operative complications. Cross-validated GBMs were implemented with and without a filtering stage non-parametric regression model to select a subset of clinically meaningful predictors. Sensitivity analysis with gradient-boosted Poisson regression models was used to examine if the same predictors were identified in the subset of patients with at least one complication. Of the 162 subjects enrolled between March 2012 and May 2018, 43 (26.5%) had at least one post-operative cardiac complication. The most frequent complications were arrhythmia requiring treatment ( = 22, 13.6%), cardiac catheterization ( = 17, 10.5%), and extracorporeal membrane oxygenation (ECMO) ( = 11, 6.8%). Fifty-six variables were used in the machine learning analysis, of which there were 21 predictors that were already identified from the first-stage regression. Duration of cardiopulmonary bypass (CPB) was the highest ranked predictor in all models. Other predictors included gestational age, pre-operative right ventricular (RV) global longitudinal strain, pulmonary valve Z-score, and immediate post-operative arterial oxygen level. Sensitivity analysis identified similar predictors, confirming the robustness of these findings across models. Cardiac complications after TOF repair are prevalent in a quarter of patients. A prolonged surgery remains an important predictor of post-operative complications; however, other perioperative factors are likewise important, including pre-operative right ventricular remodeling. This study identifies potential opportunities to optimize the surgical repair for TOF to diminish post-operative complications and secure improved clinical outcomes. Efforts toward optimizing pre-operative ventricular remodeling might mitigate post-operative complications and help reduce future morbidity.</p>

Abstract
<p><strong>PURPOSE: </strong>Parents of children with cancer exhibit high levels of psychological distress. Parents of children with serious illness report religion and spirituality are important coping resources. We sought to describe characteristics of religion, religious coping, social support, and resiliency in parents of children newly diagnosed with cancer and examine associations between psychological distress and self-reported religious coping, religiosity, resiliency, and social support.</p>
<p><strong>PATIENTS AND METHODS: </strong>Cross-sectional observational study of 100 parents of 81 unique children recently diagnosed with cancer. Parents provided demographic information and completed measures of psychological distress, importance of religion, religious coping, resiliency, and social support. Patients' type of tumor and intensity of treatment were collected by medical record abstraction.</p>
<p><strong>RESULTS: </strong>Compared to nationally reported data for adults, parents of children with cancer reported high scores for psychological distress but similar levels of religiosity, religious coping, and resiliency. Negative religious coping (feelings of negativity related to the divine) was associated with higher levels of psychological distress. This effect was most prominent in parents who reported the highest levels of religiosity. Positive religious coping, religiosity, and social support were not associated with levels of psychological distress.</p>
<p><strong>DISCUSSION: </strong>Findings confirm high levels of distress for parents of children with cancer. Negative religious coping was associated with higher levels of psychological distress but positive religious coping, religiosity, and other coping factors were not found to be significantly associated with distress. Further assessment of negative religious coping to inform interventions to promote resiliency is warranted as they may impact parental decision-making and care.</p>
