Abstract
Background: To develop a more holistic measure of congenital heart center performance beyond mortality, we created a composite "textbook outcome" (TO) for the Glenn operation. We hypothesized that meeting TO would have a positive prognostic and financial impact. Methods: This was a single center retrospective study of patients undergoing superior cavopulmonary connection (bidirectional Glenn or Kawashima ± concomitant procedures) from 2005 to 2021. Textbook outcome was defined as freedom from operative mortality, reintervention, 30-day readmission, extracorporeal membrane oxygenation, major thrombotic complication, length of stay (LOS) >75th percentile (17d), and mechanical ventilation duration >75th percentile (2d). Multivariable logistic regression and Cox proportional hazards modeling were used. Results: Fifty-one percent (137/269) of patients met TO. Common reasons for TO failure were prolonged LOS (78/132, 59%) and ventilator duration (67/132, 51%). In multivariable analysis, higher weight [odds ratio, OR: 1.44 (95% confidence interval, CI: 1.15-1.84), P = .002] was a positive predictor of TO achievement while right ventricular dominance [OR 0.47 (0.27-0.81), P = .007] and higher preoperative pulmonary vascular resistance [OR 0.58 (0.40-0.82), P = .003] were negative predictors. After controlling for preoperative factors and excluding operative mortalities, TO achievement was independently associated with a decreased risk of death over long-term follow-up [hazard ratio: 0.50 (0.25-0.99), P = .049]. Textbook outcome achievement was also associated with lower direct cost of care [$137,626 (59,333-167,523) vs $262,299 (114,200-358,844), P < .0001]. Conclusion: Achievement of the Glenn TO is associated with long-term survival and lower costs and can be predicted by certain risk factors. As outcomes continue to improve within congenital heart surgery, operative mortality will become a less informative metric. Textbook outcome analysis may represent a more balanced measure of a successful outcome.

Front Cardiovasc Med 2024; 11:1355989. [PMID: 38516005 PMCID: PMC10955132 DOI: 10.3389/fcvm.2024.1355989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 02/22/2024] [Indexed: 03/23/2024] Open
Abstract
Background Hypoplastic left heart syndrome (HLHS) accounts for 2.6% of congenital heart disease and is an invariably fatal cardiac anomaly if left untreated. Approximately 33,750 babies are born annually with HLHS in developing countries. Unfortunately, the majority will not survive due to the scarcity of resources and the limited availability of surgical management. Aim To describe and analyze our experience with the hybrid approach in the management of HLHS in a developing country. Methods We performed a retrospective single-center study involving all neonates born with HLHS over five years at the Children's Heart Center at the American University of Beirut. The medical records of patients who underwent the hybrid stage 1 palliation were reviewed, and data related to baseline characteristics, procedure details and outcomes were collected to describe the experience at a tertiary care center in a developing country. Results A total of 18 patients were diagnosed with HLHS over a five-year period at our institution, with male to female ratio of 1:1. Of those, eight patients underwent the hybrid stage I procedure. The mean weight at the time of the procedure was 3.3 ± 0.3 kg with an average age of 6.4 ± 4 days. The mean hospital length of stay was 27.25 days, with an interquartile range of 33 days. The cohort's follow-up duration averaged 5.9 ± 3.5 years. The surgical mortality was zero. Only one mortality was recorded during the interstage period between stage I and II and was attributed to sepsis. Notably, all surviving patients maintained preserved and satisfactory cardiac function with good clinical status. Conclusion Our limited experience underscores the potential of developing countries with proper foundations to adopt the hybrid procedure for HLHS, yielding outcomes on par with those observed in developed countries. This demonstrates the viability of establishing a more balanced global landscape for children with congenital heart disease.

Abstract
BACKGROUND The cardiovascular adaptations associated with structured exercise training in Fontan patients remain unknown. We hypothesised that short-term training causes cardiac remodelling and parallel improvement in maximal exercise capacity (VO2 max) in these patients. METHODS AND RESULTS Five patients, median age 19.5 (17.6-21.3) years, with a history of Fontan operation meeting inclusion/exclusion criteria, participated in a 3-month training programme designed to improve endurance. Magnetic resonance images for assessment of cardiac function, fibrosis, cardiac output, and liver elastography to assess stiffness were obtained at baseline and after training. Maximal exercise capacity (VO2 max) and cardiac output Qc (effective pulmonary blood flow) at rest and during exercise were measured (C2H2 rebreathing) at the same interval. VO2 max increased from median (IQR) 27.2 (26-28.7) to 29.6 (28.5-32.2) ml/min/kg (p = 0.04). There was an improvement in cardiac output (Qc) during maximal exercise testing from median (IQR) 10.3 (10.1-12.3) to 12.3 (10.9-14.9) l/min, but this change was variable (p = 0.14). Improvement in VO2 max correlated with an increase in ventricular mass (r = 0.95, p = 0.01), and improvement in Quality-of-life inventory (PedsQL) Cardiac scale scores for patient-reported symptoms (r = 0.90, p = 0.03) and cognitive problems (r = 0.89, p = 0.04). The correlation between VO2 max and Qc showed a positive trend but was not significant (r = 0.8, p = 0.08). No adverse cardiac or liver adaptations were noted. CONCLUSION Short-term training improved exercise capacity in this Fontan pilot without any adverse cardiac or liver adaptations. These results warrant further study in a larger population and over a longer duration of time.

Preoperative Hemodynamics Impact the Benefit of Fenestration on Fontan Postoperative Length of Stay. JACC. ADVANCES 2024; 3:100846.

Abstract
BACKGROUND Utilization of Fontan fenestration varies considerably by center. OBJECTIVES Using a multicenter Pediatric Heart Network dataset linking surgical and preoperative hemodynamic variables, the authors evaluated factors associated with use of Fontan fenestration and the impact of fenestration on post-Fontan length of stay (LOS). METHODS Patients 2 to 6 years old at Fontan surgery from 2010 to 2020 with catheterization<1 year prior were included. Factors associated with fenestration were evaluated using multivariable logistic regression adjusting for key covariates. Restrictive cubic spline analysis was used to evaluate potential cut-points for hemodynamic variables associated with longer postoperative LOS stratified by fenestration with multivariable linear regression to evaluate the magnitude of effect. RESULTS Fenestration was used in 465 of 702 patients (66.2%). Placement of a fenestration was associated with center (range 27%-93% use, P < 0.0001) and Fontan type (OR: 14.1 for lateral tunnel vs extracardiac conduit, P < 0.0001). No hemodynamic variable was independently associated with fenestration. In a multivariable linear model adjusting for center, a center-fenestration interaction, prematurity, preoperative mean pulmonary artery pressure (mPAP), and cardiac index, fenestration was associated with shorter hospital LOS after Fontan (P = 0.0024). The benefit was most pronounced at mPAP ≥13 mm Hg (median LOS: 9 vs 12 days, P = 0.001). CONCLUSIONS There is wide center variability in use of Fontan fenestration that is not explained by preoperative hemodynamics. Fenestration is independently associated with shorter LOS, and those with mPAP ≥13 mm Hg at pre-Fontan catheterization benefit the most. We propose this threshold as minimal criteria for fenestration.

Abstract
Completing 3-stage palliation for hypoplastic left heart syndrome requires significant resources. An analysis of recent data has not been performed. We aimed to determine total charges necessary to complete all 3 stages of single-ventricle palliation, including interstage encounters. We also aimed to determine overall resource utilization, including hospital days, interstage admissions, and interstage procedures. We performed a retrospective cohort study using data from the Pediatric Health Information System database between 2016 and 2021, including all patients who completed 3-stage palliation for hypoplastic left heart syndrome. We identified 199 patients who underwent 3-stage palliation of hypoplastic left heart syndrome between 2016 and 2021. Median total adjusted charges (interquartile range, IQR) over the course of 3-stage palliation were $1,475,800 ($1,028,900-2,191,700). Median adjusted charges (IQR) for stage 1, 2, and 3 hospitalizations were $604,300 ($419,000-891,400), $234,000 ($164,300-370,800), and $256,260 ($178,300-345,900), respectively. Median hospital length of stay (IQR) for stages 1, 2, and 3 was 36 (26,53), 9 (6,17), and 10 (7,14) days, respectively. Pulmonary artery stenosis was the most common admitting diagnosis for interstage hospitalizations (3.4% of hospitalizations). Cardiac catheterization (24.1% of procedures) and feeding tube placement (10.0% of procedures) were the most common principal procedures during interstage hospitalizations. Total inpatient charges incurred throughout 3-stage palliation of hypoplastic left heart syndrome are substantial and have risen since prior studies. Gastrointestinal comorbidities and feeding optimization contribute considerably to this resource utilization.

Abstract
BACKGROUND Stage 1 single ventricle palliation (S1P) has the longest length of stay (LOS) of all benchmark congenital heart operations. Center-level factors contributing to prolonged hospitalization are poorly defined. METHODS We analyzed data from infants status post S1P included in the National Pediatric Cardiology Quality Improvement Collaborative Phase II registry. Our primary outcome was patient-level LOS with days alive and out of hospital before stage 2 palliation (S2P) used as a balancing measure. We compared patient and center-level characteristics across quartiles for median center LOS, and used multivariable regression to calculate center-level factors associated with LOS after adjusting for case mix. RESULTS Of 2,510 infants (65 sites), 2037 (47 sites) met study criteria (61% male, 61% white, 72% hypoplastic left heart syndrome). There was wide intercenter variation in LOS (first quartile centers: median 28 days [IQR 19, 46]; fourth quartile: 62 days [35, 95], P < .001). Mortality prior to S2P did not differ across quartiles. Shorter LOS correlated with more pre-S2P days alive and out of hospital, after accounting for readmissions (correlation coefficient -0.48, P < .001). In multivariable analysis, increased use of Norwood with a right ventricle to pulmonary artery conduit (aOR 2.65 [1.1, 6.37]), shorter bypass time (aOR 0.99 per minute [0.98,1.0]), fewer additional cardiac operations (aOR 0.46 [0.22, 0.93]), and increased use of NG tubes rather than G tubes (aOR 7.03 [1.95, 25.42]) were all associated with shorter LOS centers. CONCLUSIONS Modifiable center-level practices may be targets to standardize practice and reduce overall LOS across centers.

Attributable mortality benefit of digoxin treatment in hypoplastic left heart syndrome after the Norwood operation: An instrumental variable-based analysis using data from the Pediatric Health Information Systems Database. Am Heart J 2023; 263:35-45. [PMID: 37169122 DOI: 10.1016/j.ahj.2023.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 05/01/2023] [Accepted: 05/04/2023] [Indexed: 05/13/2023]
Abstract
BACKGROUND Observational studies have demonstrated an association between the use of digoxin and reduced interstage mortality after Norwood operation for hypoplastic left heart syndrome (HLHS). Digoxin use has increased significantly but remains variable between different hospitals, independent of case-mix. Instrumental variable analyses have the potential to overcome unmeasured confounding, the major limitation of previous observational studies and to generate an estimate of the attributable benefit of treatment with digoxin. METHODS A cohort of neonates with HLHS born from January 1, 2007 to December 31, 2021 who underwent Norwood operation at Pediatric Health Information Systems Database hospitals and survived >14 days after operation were studied. Using hospital-specific, 6-month likelihood of administering digoxin as an instrumental variable, analyses adjusting for both unmeasured confounding (using the instrumental variable) and measured confounders with multivariable logistic regression were performed. RESULTS The study population included 5,148 subjects treated at 47 hospitals of which 63% were male and 46% non-Hispanic white. Of these, 44% (n = 2,184) were prescribed digoxin. Treatment with digoxin was associated with superior 1-year transplant-free survival in unadjusted analyses (85% vs 82%, P = .02). This survival benefit persisted in an instrumental-variable analysis (OR: 0.71, 95% CI: 0.54-0.94, P = .01), which can be converted to an absolute risk reduction of 5% (number needed to treat of 20). CONCLUSIONS In this observational study of patients with HLHS after Norwood using instrumental variable techniques, a significant benefit in 1-year transplant-free survival attributable to digoxin was demonstrated. In the absence of clinical trial data, this should encourage the use of digoxin in this vulnerable population.

Hospital resource utilization in a national cohort of functionally single ventricle patients undergoing surgical treatment. JTCVS OPEN 2023; 14:441-461. [PMID: 37425480 PMCID: PMC10329026 DOI: 10.1016/j.xjon.2023.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 02/22/2023] [Accepted: 03/27/2023] [Indexed: 07/11/2023]
Abstract
Objective The study objective was to provide a detailed overview of health resource use from birth to 18 years old for patients with functionally single ventricles and identify associated risk factors. Methods All patients with functionally single ventricles treated between 2000 and 2017 in England and Wales were linked to hospital and outpatient records using data from the Linking AUdit and National datasets in Congenital HEart Services project. Hospital stay was described in yearly age intervals, and associated risk factors were explored using quantile regression. Results A total of 3037 patients with functionally single ventricles were included, 1409 (46.3%) undergoing a Fontan procedure. During the first year of life, the median days spent in hospital was 60 (interquartile range, 37-102), mostly inpatient days, mirroring a mortality of 22.8%. This decreases to between 2 and 9 in-hospital days/year afterward. Between 2 and 18 years, most hospital days were outpatient, with a median of 1 to 5 days/year. Lower age at the first procedure, hypoplastic left heart syndrome/mitral atresia, unbalanced atrioventricular septal defect, preterm birth, congenital/acquired comorbidities, additional cardiac risk factors, and severity of illness markers were associated with fewer days at home and more intensive care unit days in the first year of life. Only markers of early severe illness were associated with fewer days at home in the first 6 months after the Fontan procedure. Conclusions Hospital resource use in functionally single ventricle cases is not uniform, decreasing 10-fold during adolescence compared with the first year of life. There are subsets of patients with worse outcomes during their first year of life or with persistently high hospital use throughout their childhood, which could be the target of future research.

Abstract
Congenital heart disease remains one of the most frequently diagnosed congenital diseases of the newborn, with hypoplastic left heart syndrome (HLHS) being considered one of the most severe. This univentricular defect was uniformly fatal until the introduction, 40 years ago, of a complex surgical palliation consisting of multiple staged procedures spanning the first 4 years of the child's life. While survival has improved substantially, particularly in experienced centers, ventricular failure requiring heart transplant and a number of associated morbidities remain ongoing clinical challenges for these patients. Cell-based therapies aimed at boosting ventricular performance are under clinical evaluation as a novel intervention to decrease morbidity associated with surgical palliation. In this review, we will examine the current burden of HLHS and current modalities for treatment, discuss various cells therapies as an intervention while delineating challenges and future directions for this therapy for HLHS and other congenital heart diseases.

Abstract
Evaluative research in interventional cardiology has focused on clinical and technical outcomes. Inclusion of economic data can enhance evaluative research by quantifying the relative economic burden incurred by different therapies. When combined with clinical outcomes, cost data can provide a measure of value (e.g., marginal cost-effectiveness). In some select situations, cost data can also be used as surrogates for complexity of care and morbidity. In this narrative review, we aim to provide a framework for the application of cost data in clinical trials and observational research, detailing how to incorporate this kind of data into interventional cardiology research.

Abstract
Hypoplastic left heart syndrome (HLHS) is among the most severe cardiovascular malformations and understanding its causes is crucial to making progress in prevention and treatment. Genetic analysis is a broadly useful tool for dissecting complex causal mechanisms and it is playing a significant role in HLHS research. However, unlike classical Mendelian disorders where a relatively small number of genes are largely determinative of the occurrence and severity of the disease, the picture in HLHS is complex. De novo single-gene and copy number variant (CNV) disorders make an important contribution, but there is emerging evidence for causal contributions from lower penetrance and common variation. Integrating this emerging knowledge into clinical diagnostics and translating the findings into effective prevention and treatment remain challenges for the future.

Abstract
Hypoplastic left heart syndrome (HLHS) is possibly the most challenging congenital heart defect to confront in any setting. The highly specialized infrastructure and resources needed to treat HLHS is not available in many low-resource settings. However, low-resource settings must not be assumed to be synonymous with low- and middle-income countries as national income is not necessarily indicative of a country's prioritization of healthcare resources. Besides, a low-resource setting may be institution-specific as well as country-specific. We have stratified institutional capabilities for addressing the requirements of treatment for HLHS into five levels based on the capacity for diagnosis, intervention, and post-discharge monitoring. Depending on institutional capabilities, children born with HLHS in low-resource settings experience a spectrum of outcomes ranging from death without diagnosis to the hybrid or Norwood stage 1 palliation. The decision-making is ethically challenging when resources are scarce and economic efficiency must be considered in the context of distributive justice. Even in settings that would be classified as resource-rich where survival after surgery and quality of life afterward keep improving, not every parent would choose surgical intervention for their hypothetical child with HLHS.

Abstract
Background In the SVR (Single Ventricle Reconstruction) Trial, 1-year survival in recipients of right ventricle to pulmonary artery shunts (RVPAS) was superior to that in those receiving modified Blalock-Taussig-Thomas shunts (MBTTS), but not in subsequent follow-up. Cost analysis is an expedient means of evaluating value and morbidity. Objectives The purpose of this study was to evaluate differences in cumulative hospital costs between RVPAS and MBTTS. Methods Clinical data from SVR and costs from Pediatric Health Information Systems database were combined. Cumulative hospital costs and cost-per-day-alive were compared serially at 1, 3, and 5 years between RVPAS and MBTTS. Potential associations between patient-level factors and cost were explored with multivariable models. Results In total, 303 participants (55% of the SVR cohort) from 9 of 15 sites were studied (48% MBTTS). Observed total costs at 1 year were lower for MBTTS ($701,260 ± 442,081) than those for RVPAS ($804,062 ± 615,068), a difference that was not statistically significant (P = 0.10). Total costs were also not significantly different at 3 and 5 years (P = 0.21 and 0.32). Similarly, cost-per-day-alive did not differ significantly for either group at 1, 3, and 5 years (all P > 0.05). In analyses of transplant-free survivors, total costs and cost-per-day-alive were higher for RVPAS at 1 year (P = 0.05 for both) but not at 3 and 5 years (P > 0.05 for all). In multivariable models, aortic atresia and prematurity were associated with increased cost-per-day-alive across follow-up (P < 0.05). Conclusions Total costs do not differ significantly between MBTTS and RVPAS. The magnitude of longitudinal costs underscores the importance of efforts to improve outcomes in this vulnerable population.

Abstract
Hypoplastic left heart syndrome (HLHS) is a life-threatening congenital heart disease that is characterized by severe underdevelopment of left heart structures. Currently, there is no cure, and affected individuals require surgical palliation or cardiac transplantation to survive. Despite these resource-intensive measures, only about half of individuals reach adulthood, often with significant comorbidities such as liver disease and neurodevelopmental disorders. A major barrier in developing effective treatments is that the etiology of HLHS is largely unknown. Here, we discuss how intracardiac blood flow disturbances are an important causal factor in the pathogenesis of impaired left heart growth. Specifically, we highlight results from a recently developed mouse model in which surgically reducing blood flow through the mitral valve after cardiogenesis led to the development of HLHS. In addition, we discuss the role of interventional procedures that are based on improving blood flow through the left heart, such as fetal aortic valvuloplasty. Lastly, using the surgically-induced mouse model, we suggest investigations that can be undertaken to identify the currently unknown biological pathways in left heart growth failure and their associated therapeutic targets.

Abstract
Hypoplastic left heart syndrome (HLHS) is the most common anatomic lesion in children born with single ventricle physiology and is characterized by the presence of a dominant right ventricle and a hypoplastic left ventricle along with small left-sided heart structures. Diagnostic subgroups of HLHS reflect the extent of inflow and outflow obstruction at the aortic and mitral valves, specifically stenosis or atresia. If left unpalliated, HLHS is a uniformly fatal lesion in infancy. Following introduction of the Norwood operation, early survival has steadily improved over the past four decades, mirroring advances in operative and peri-operative management as well as reflecting refinements in patient surveillance and interstage clinical care. Notably, survival following staged palliation has increased from 0% to a 5-year survival of 60-65% for children in some centres. Despite the prevalence of HLHS in childhood with relatively favourable surgical outcomes in contemporary series, this cohort is only now reaching early adult life and longer-term outcomes have yet to be elucidated. In this article we focus on contemporary clinical management strategies for patients with HLHS across the lifespan, from fetal to adult life. Nomenclature and diagnostic considerations are discussed and current literature pertaining to putative genetic etiologies is reviewed. The spectrum of fetal and pediatric interventional strategies, both percutaneous and surgical, are described. Clinical, patient-reported and neurodevelopmental outcomes of HLHS are delineated. Finally, note is made of current areas of clinical uncertainty and suggested directions for future research are highlighted.

Abstract
Socioeconomic status (SES) affects a range of health outcomes but has not been extensively explored in the single ventricle population. We investigate the impact of community-level deprivation on morbidity and mortality for infants with single ventricle heart disease in the first year of life. Retrospective cohort analysis of infants enrolled in the National Pediatric Cardiology Improvement Collaborative who underwent staged single ventricle palliation examining mortality and length of stay (LOS) using a community-level deprivation index (DI). 974 patients met inclusion criteria. Overall mortality was 20.5%, with 15.7% of deaths occurring between the first and second palliations. After adjusting for clinical risk factors, the DI was associated with death (log relative hazard [Formula: see text] = 8.92, p = 0.030) and death or transplant (log relative hazard [Formula: see text] = 8.62, p = 0.035) in a non-linear fashion, impacting those near the mean DI. Deprivation was associated with LOS following the first surgical palliation (S1P) (p = 0.031) and overall hospitalization during the first year of life (p = 0.018). For every 0.1 increase in the DI, LOS following S1P increased by 3.35 days (95% confidence interval 0.31-6.38) and total hospitalized days by 5.08 days (95% CI 0.88-9.27). Community deprivation is associated with mortality and LOS for patients with single ventricle congenital heart disease. While patients near the mean DI had a higher hazard of one year mortality compared to those at the extremes of the DI, LOS and DI were linearly associated, demonstrating the complex nature of SES factors.

Abstract
Background The hybrid comprehensive stage 2 (HCS2) procedure is a novel palliative operation applicable to a select subset of single ventricle patients with adequate native antegrade aortic flow to the upper body. Flow to the descending aorta, through the pulmonary outlet and ductal arch, is influenced by a stented intrapulmonary baffle connecting the branch pulmonary arteries. We used computational fluid dynamics (CFD) to elucidate the hemodynamic characteristics of this reconstruction. Methods We used multiscale CFD analysis of a synthetic, patient-derived HCS2 anatomic configuration with unsteady laminar flow conditions and a non-Newtonian blood model to quantify the resultant hemodynamics. The 3-dimensional CFD model was coupled to a 0-dimensional lumped parameter model of the peripheral circulation to determine the required boundary conditions. Results For the specific anatomy studied, the intrapulmonary baffle did not obstruct flow from the pulmonary trunk to ductal arch as long as the distance between the anterior pulmonary artery wall and baffle wall exceeded ∼7 mm. Vortex shedding off of the baffle wall did not develop, because of the short distance to the ductal arch. The stented baffle experienced significantly uneven "inward" loading from the systemic side. Pulmonary outlet flow separation distal to the baffle produced a low-speed recirculation region. Conclusions Hemodynamic patterns in this complex anatomy are generally favorable. Low flow recirculation could be mitigated by preoperative shape optimization. Calculated inward stresses on the pulmonary baffle can be used in the future to study baffle stent deformation, which is expected to be small.

Abstract
OBJECTIVE Describe NICU admission rate variation among hospitals in infants with birthweight ≥2500 g and low illness acuity, and describe factors that predict NICU admission. STUDY DESIGN Retrospective study from the Vizient Clinical Data Base/Resource Manager®. Support vector machine methodology was used to develop statistical models using (1) patient characteristics (2) only the indicator for the inborn hospital and (3) patient characteristics plus indicator for the inborn hospital. RESULTS NICU admission rates of 427,449 infants from 154 hospitals ranged from 0 to 28.6%. C-statistics for the patient characteristics model: 0.64 (Confidence Interval (CI) 0.62-0.65), hospital only model: 0.81 (CI, 0.81-0.82), and patient characteristic plus hospital variable model: 0.84 (CI, 0.83-0.84). CONCLUSION/RELEVANCE There is wide variation in NICU admission rates in infants with low acuity diagnoses. In all cohorts, birth hospital better predicted NICU admission than patient characteristics alone.

Abstract
Background Children with congenital heart disease (CHD) are known to consume a disproportionate share of resources, yet there are limited data concerning trends in resource use and mortality among admitted children with CHD. We hypothesize that charges in CHD‐related admissions increased but that mortality improved over time. Methods and Results This study, including patients <18 years old with CHD, examined inpatient admissions from the nationally representative Kids' Inpatient Database from 2003 to 2016 in order to assess the frequency, medical complexity, and outcomes of CHD hospital admissions. A total of 859 843 admissions of children with CHD were identified. CHD admissions increased by 31.8% from 2003 to 2016, whereas overall pediatric admissions decreased by 13.4%. Compared with non‐CHD admissions, those with CHD were more likely to be <1 year of age (80.5% versus 63.3%), and to have ≥1 complex chronic condition (39.7% versus 9.3%). For CHD admissions, mortality was higher (2.97% versus 0.31%) and adjusted median charges greater ($48 426 [interquartile range (IQR), $11.932–$161 048] versus $4697 [IQR, $2551–$12 301]) (P<0.0001 for all). Among CHD admissions, whereas adjusted median charges increased from $35 577 (IQR, $9303–$110 439) to $61 696 (IQR, $15 212–$219 237), mortality decreased from 3.2% to 2.7% (P for trend <0.0001). CHD admissions accounted for an increased proportion of all inpatient deaths, from 18.0% in 2003 to 24.5% in 2016. Conclusions Children admitted with CHD are 10 times more likely to die than those without CHD and have higher charges. Although the rate of mortality in CHD admissions decreased, children with CHD accounted for an increasing proportion of all pediatric inpatient deaths. Effective resource allocation is critical to optimize outcomes in these high‐risk patients.

Abstract
Previous reports have identified risk factors associated with development of post-Fontan protein-losing enteropathy. Less is known about the economic impact and resource utilisation required for post-Fontan protein-losing enteropathy in the current era. We conducted a single-centre retrospective study to assess the impact of post-Fontan protein-losing enteropathy on transplant-free survival. We also described resource utilisation and treatment variations among post-Fontan protein-losing enteropathy patients. Children who received care at our centre between 2009 and 2017 after the Fontan surgery were eligible. Initial admissions for the Fontan operative procedure were excluded. Demographics, hospital admissions, resource utilisation, medications and charges were reviewed. Patients were divided into two groups based on the presence of post-Fontan protein-losing enteropathy. Of the 343 patients screened, 147 met the eligibility criteria. Of these, 28 (19%) developed protein-losing enteropathy. After adjusting for follow-up duration, the protein-losing enteropathy group had higher number of encounters (2.15 ± 2.16 versus 1.47 ± 2.56, p 0.002), hospital length of stay (days) (25 ± 51.3 versus 11.4 ± 41.7, p < 0.0001) and total charges (2018US$) (388,489 ± 759,859 versus 202,725 ± 1,076,625, p < 0.0001). Encounters for patients with protein-losing enteropathy utilised more therapies. Among those with protein-losing enteropathy, use of digoxin was associated with slightly decreased odds for mortality and/or transplant (0.95, confidence interval 0.90-0.99, p 0.021). The 10-year transplant-free survival for patients with/without protein-losing enteropathy was 65.7/97.3% (p 0.002), respectively. Post-Fontan protein-losing enteropathy is associated with reduced 10-year transplant-free survival, higher resource utilisation, charges and medication use compared with the non-protein-losing enteropathy group. Practice variation among post-Fontan protein-losing-enteropathy patients is common. Further larger studies are needed to assess the impact of standardisation on the well-being of children with post-Fontan protein-losing enteropathy.

Abstract
INTRODUCTION The Fontan procedure is the final stage of surgical palliation for the children with functionally single ventricle anatomy. The post-operative medical management of this patient population can be variable and hospital length of stay prolonged. The purpose of this quality improvement project was to determine if the implementation of an evidence-based clinical pathway for post-operative management of the Fontan patient at a large Midwestern academic paediatric medical centre would standardise care and decrease length of stay. MATERIALS AND METHODS The clinical pathway was developed using key components from three published pathways for the Fontan procedure from other paediatric institutions across the United States. Components of the clinical pathway included (1) supplemental oxygen until pleural drainage tubes are removed, (2) fluid restriction to 80% daily maintenance and a prescribed low-fat diet, (3) aggressive and standardised diuretic therapy while inpatient and (4) central venous access. The pathway was trialed using Plan-Do-Study-Act cycles in 2016, implemented in 2017 and sustained in 2018-2019. A retrospective electronic medical record review was performed to compare key outcomes from pre-pathway (2014-2015, 37 patients) with post-pathway implementation (2017-2018, 30 patients). RESULTS Adherence to the pathway was nearly 100% with a statistically significant decrease in length of stay from 12 to 9 days (p = 0.007) and no increase in readmissions. CONCLUSION Standardising care can improve clinical and financial outcomes for the Fontan patient population without negatively impacting quality of care, thus providing a positive benefit to the healthcare institution, industry and patient.

Abstract
The Norwood surgical procedure restores functional systemic circulation in neonatal patients with single ventricle congenital heart defects, but this complex procedure carries a high mortality rate. In this study we address the need to provide an accurate patient specific risk prediction for one-year postoperative mortality or cardiac transplantation and prolonged length of hospital stay with the purpose of assisting clinicians and patients' families in the preoperative decision making process. Currently available risk prediction models either do not provide patient specific risk factors or only predict in-hospital mortality rates. We apply machine learning models to predict and calculate individual patient risk for mortality and prolonged length of stay using the Pediatric Heart Network Single Ventricle Reconstruction trial dataset. We applied a Markov Chain Monte-Carlo simulation method to impute missing data and then fed the selected variables to multiple machine learning models. The individual risk of mortality or cardiac transplantation calculation produced by our deep neural network model demonstrated 89 ± 4% accuracy and 0.95 ± 0.02 area under the receiver operating characteristic curve (AUROC). The C-statistics results for prediction of prolonged length of stay were 85 ± 3% accuracy and AUROC 0.94 ± 0.04. These predictive models and calculator may help to inform clinical and organizational decision making.

Impact of Confounding on Cost, Survival, and Length-of-Stay Outcomes for Neonates with Hypoplastic Left Heart Syndrome Undergoing Stage 1 Palliation Surgery. Pediatr Cardiol 2020; 41:996-1011. [PMID: 32337623 DOI: 10.1007/s00246-020-02348-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 04/15/2020] [Indexed: 11/30/2022]
Abstract
The objective of this analysis was to update trends in LOS and costs by survivorship and ECMO use among neonates with hypoplastic left heart syndrome (HLHS) undergoing stage 1 palliation surgery using 2016 data from the Healthcare Cost and Utilization Project Kids' Inpatient Database. We identified neonates ≤ 28 days old with HLHS undergoing Stage 1 surgery, defined as a Norwood procedure with modified Blalock-Taussig (BT) shunt, Sano modification, or both. Multivariable regression with year random effects was used to compare LOS and costs by hospital region, case volume, survivorship, and ECMO vs. no ECMO. An E-value analysis, an approach for conducting sensitivity analysis for unmeasured confounding, was performed to determine if unmeasured confounding contributed to the observed effects. Significant differences in total costs, LOS, and mortality were noted by hospital region, ECMO use, and sub-analyses of case volume. However, other than ECMO use and mortality, the maximum E-value confidence interval bound was 1.71, suggesting that these differences would disappear with an unmeasured confounder 1.71 times more associated with both the outcome and exposure (e.g., socioeconomic factors, environment, etc.) Our findings confirm previous literature demonstrating significant resource utilization among Norwood patients, particularly those undergoing ECMO use. Based on our E-value analysis, differences by hospital region and case volume can be explained by moderate unobserved confounding, rather than a reflection of the quality of care provided. Future analyses on surgical quality must account for unobserved factors to provide meaningful information for quality improvement.

[PMID: 31741094 DOI: 10.1007/s00431-019-03508-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 10/09/2019] [Accepted: 10/14/2019] [Indexed: 11/28/2022]
Abstract
Neonates with hypoplastic left heart syndrome (HLHS) were identified from the National Inpatient Sample dataset for the years 1998-2014. These patients were stratified into two chronological groups, past group (1998-2005) and recent group (2006-2014). A total of 20,649 neonates with HLHS were identified. Of them, 9179 (44.5%) were born in the past group and 11,470 (55.5%) in the recent group. Median birth weight was significantly less in the recent group (2967 g vs. 3110 g, p = 0.005). The patients in the recent group had more patients with low birth weight ( < 2.5 kg) and prematurity (8.7% vs 7.6% and 12.7% vs. 4.3%., respectively). In addition, recent group had more comorbidities including chromosomal anomalies, total anomalous pulmonary venous return, and kidney anomalies (5.6% vs. 3.6%, 2.3% vs. 1.7%, and 5.6% vs. 3.6%, respectively, p < 0.001); these were associated with a higher rate of extracorporeal membrane oxygenation utilization (9.2% vs. 4.5%, p < 0.001). Consequently, median length of stay was longer in the recent group (8 vs. 6 days, p < 0.001).Conclusion: Despite the higher frequency of comorbidities in recent group, the mortality rates decreased by 20% (from 25.3% to 20.6%, p < 0.001). Balloon atrial septostomy was performed less frequently in the recent group (23.3% vs. 16.1%, p < 0.001).What is known:• Hypoplastic left heart syndrome has the highest mortality among congenital cardiac defects during the first year of life.• Limited studies on patients' comorbidities and mortality rates trends over last two decades.What is new:• The study utilized a national database to compare in-hospital mortality and length of stay between the two time periods 1998-2005 and 2006-2014.• The recent group had more comorbidities (prematurity, chromosomal anomalies, total anomalous pulmonary venous return, and kidney anomalies), and there was higher rate of ECMO and longer length of stay, while mortality rates decreased by 20%.

Abstract
BACKGROUND The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals. RESULTS Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Abstract
OBJECTIVES Postoperative fluid overload is ubiquitous in neonates and infants following operative intervention for congenital heart defects; ineffective diuresis is associated with poor outcomes. Diuresis with furosemide is widely used, yet there is often resistance at higher doses. In theory, furosemide resistance may be overcome with chlorothiazide; however, its efficacy is unclear, especially in lower doses and in this population. We hypothesized the addition of lower-dose, intravenous chlorothiazide following surgery in patients on high-dose furosemide would induce meaningful diuresis with minimal side effects. METHODS This was a retrospective, cohort study. Postoperative infants younger than 6 months, receiving high-dose furosemide, and given lower-dose chlorothiazide (1-2 mg/kg every 6-12 hours) were identified. Diuretic doses, urine output, fluid balance, vasoactive-inotropic scores, total fluid intake, and electrolyte levels were recorded. RESULTS There were 73 patients included. The addition of lower-dose chlorothiazide was associated with a significant increase in urine output (3.8 ± 0.18 vs 5.6 ± 0.27 mL/kg/hr, p < 0.001), more negative fluid balance (16.1 ± 4.2 vs -25.0 ± 6.3 mL/kg/day, p < 0.001), and marginal changes in electrolytes. Multivariate analysis was performed, demonstrating that increased urine output and more negative fluid balance were independently associated with addition of chlorothiazide. Subgroup analysis of 21 patients without a change in furosemide dose demonstrated the addition of chlorothiazide significantly increased urine output (p = 0.03) and reduced fluid balance (p < 0.01), further validating the adjunct effects of chlorothiazide. CONCLUSION Lower-dose, intravenous chlorothiazide is an effective adjunct treatment in postoperative neonates and infants younger than 6 months following cardiothoracic surgery.

Abstract
BACKGROUND Data related to the epidemiology and resource utilization of congenital heart disease (CHD)-related emergency department (ED) visits in the pediatric population is limited. OBJECTIVES The purpose of this analysis was to describe national estimates of pediatric CHD-related ED visits and evaluate medical complexity, admissions, resource utilization, and mortality. METHODS This was an epidemiological analysis of ED visit-level data from the 2006 to 2014 Nationwide Emergency Department Sample. Patients age <18 years with CHD were identified using International Classification of Diseases-9th Revision-Clinical Modification codes. We evaluated time trends using weighted regression and tested the hypothesis that medical complexity, resource utilization, and mortality are higher in CHD patients. RESULTS A total of 420,452 CHD-related ED visits (95% confidence interval [CI]: 416,897 to 422,443 visits) were identified, accounting for 0.17% of all pediatric ED visits. Those with CHD were more likely to be <1 year of age (43% vs. 13%), and to have ≥1 complex chronic condition (35% vs. 2%). CHD-related ED visits had higher rates of inpatient admission (46% vs. 4%; adjusted odds ratio: 1.89; 95% CI: 1.85 to 1.93), higher median ED charges ($1,266 [interquartile range (IQR): $701 to $2,093] vs. $741 [IQR: $401 to $1,332]), and a higher mortality rate (1% vs. 0.04%; adjusted odds ratio: 1.25; 95% CI: 1.07 to 1.45). Adjusted median charges for CHD-related ED visits increased from $1,219 (IQR: $673 to $2,138) to $1,630 (IQR: $901 to $2,799), while the mortality rate decreased from 1.13% (95% CI: 0.71% to 1.52%) to 0.75% (95% CI: 0.41% to 1.09%) over the 9 years studied. CONCLUSIONS Children with CHD presenting to the ED represent a medically complex population at increased risk for morbidity, mortality, and resource utilization compared with those without CHD. Over 9 years, charges increased, but the mortality rate improved.

Abstract
BACKGROUND We report our intermediate-term results after Norwood procedure, including use of an interstage inpatient management strategy for high-risk patients, and seek to create a predictive model for probability of discharge. METHODS A single-site retrospective review was conducted for all patients undergoing Norwood procedure from 2006 to 2016 (N = 177). We compared those discharged home with those who either remained hospitalized until Glenn procedure or died before Norwood procedure discharge. Multivariable logistic regression was used to develop a predictive model for discharge. RESULTS During the study period, 120 (68%) patients were discharged home, 45 (25%) remained hospitalized, and 12 (7%) died before Glenn procedure (median age: 71 days). Interstage survival for those discharged after Norwood procedure was 100%. Longitudinal survival for the cohort was 86%, 81%, and 77% at 1, 5, and 10 years, resepectively. Ten-year survival was significantly greater for the discharged group compared with the interstage inpatients (86% vs 56%, P < .001). A reduced predictive model of discharge included lower gestational age (odds ratio [OR]: 0.95), lower median income for ZIP code (OR: 0.4), lower birth-weight-for-age z-score (OR: 0.56), longer cardiopulmonary bypass time (OR: 0.45), and Blalock-Taussig shunt (OR: 0.32). CONCLUSIONS Survival up to 10 years after Norwood procedure is good using a strategy of inpatient care for a subset of high-risk patients to mitigate home interstage mortality. A probabilistic model used after Norwood procedure was able to predict interstage discharge with good accuracy, but will require external validation to ensure generalizability. Further work is also needed to determine optimal palliative pathways for the high-risk patients because of the notable attrition beyond successful bidirectional Glenn procedure.

Bradford TT, Daily JA, Lang SM, Gossett JM, Tang X, Collins RT. Comparison of inhospital outcomes of pediatric heart transplantation between single ventricle congenital heart disease and cardiomyopathy. Pediatr Transplant 2019; 23:e13495.

Abstract
Data investigating the impact of household income and other factors on SV patient status-post-Fontan palliation after heart transplantation are lacking. We aim to evaluate factors affecting outcomes after OHT in this population. The PHIS database was interrogated for either SV or myocarditis/primary CM who were 4 years or older who underwent a single OHT. There were 1599 patients with a median age of 13.2 years (IQR: 9.3-16.1). Total hospital costs were significantly higher in the SV group ($408 000 vs $294 000, P < 0.0001), but as median household income increased, the risk of inhospital mortality, post-transplant LOS, and LOS-adjusted total hospital costs all decreased. The risk of inhospital mortality increased 6.5% per 1 year of age increase at the time of transplant. Patients in the SV group had significantly more diagnoses than those in the CM group (21 vs 15, P < 0.0001) and had longer total hospital LOSs as a result of longer post-transplant courses (25 days vs 15, P < 0.0001). Increased median household income and younger age are associated with decreased resource utilization and improved inhospital mortality in SV CHD patients who undergo OHT. In conclusion, earlier consideration of OHT in this population, coupled with improved selection criteria, may increase survival in this population.

Abstract
BACKGROUND Resource utilisation for infants with single ventricle CHD remains high without well-studied ways to decrease economic burden. Same-day discharge following cardiac catheterisation has been shown to be safe and effective in children with CHD, but those with single ventricle physiology are commonly excluded. The purpose of this study was to investigate the economic implications of planned same-day discharge following cardiac catheterisation versus universal overnight hospital admission in infants with single ventricle CHD. METHODS AND RESULTS A probabilistic decision-tree analysis with sensitivity analyses was performed. All included patients were categorised into four possible outcomes; discharge, readmission following discharge (within 48 hours), observation and prolonged hospitalisation. Baseline probabilities of each node of the tree were then combined with the cost data to evaluate the comparative dominance of one decision (immediately discharge) versus the other decision (routinely admit). Patients discharged on the same day as the procedure accrued the lowest attributed hospital cost ($5469), while patients readmitted to the hospital had the highest attributed cost ($11,851). Currently, no other studies have assessed the cost of hospitalisation following cardiac catheterisation in this population. Thus, we allowed for a wide range of cost variation, but same-day discharge dominated the decision outcome with a lower economic burden. CONCLUSION Same-day discharge following routine cardiac catheterisation in patients with single ventricle physiology is less costly compared to universal overnight admission. This demonstrates an important cost-limiting step in a complex population of patients who have high resource utilisation.

Abstract
Background Healthcare resource utilization is substantial for single‐ventricle cardiac defects (SVCD), with effort commencing at time of fetal diagnosis through staged surgical palliation. We sought to characterize and identify variables that influence resource utilization for SVCD from fetal diagnosis through death, completed staged palliation, or cardiac transplant. Methods and Results Patients with a prenatal diagnosis of SVCD at our institution from 2004 to 2011 were screened. Patients delivered with intent to treat who received cardiac care exclusively at our institution were included. Primary end points included the total days hospitalized and the numbers of echocardiograms and cardiac catheterizations. Subanalysis was performed on survivors of completed staged palliation on the basis of Norwood operation, dominant ventricular morphology, and additional risk factors. Of 202 patients born with intent to treat, 136 patients survived to 6 months after completed staged palliation. The median number of days hospitalized per patient‐year was 25.1 days, and the median numbers of echocardiograms and catheterizations per patient‐year were 7.2 and 0.7, respectively. Mortality is associated with increased resource utilization. Survivors had a cumulative length of stay of 57 days and underwent a median of 21 echocardiograms and 2 catheterizations through staged palliation. Right‐ventricle–dominant lesions requiring Norwood operation are associated with increased resource utilization among survivors of staged palliation. Conclusions For fetuses with SVCD, those with dominant right‐ventricular morphology requiring Norwood operation demand increased resource utilization regardless of mortality. Our findings provide insight into care for SVCD, facilitate precise prenatal counseling, and provide information about the resources utilized to successfully manage SVCD.

The Case for Cardiac Xenotransplantation in Neonates: Is Now the Time to Reconsider Xenotransplantation for Hypoplastic Left Heart Syndrome? Pediatr Cardiol 2019; 40:437-444. [PMID: 30302505 DOI: 10.1007/s00246-018-1998-1] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Accepted: 09/28/2018] [Indexed: 01/06/2023]
Abstract
Neonatal cardiac transplantation for hypoplastic left heart syndrome (HLHS) is associated with excellent long-term survival compared to older recipients. However, heart transplantation for neonates is greatly limited by the critical shortage of donor hearts, and by the associated mortality of the long pre-transplant waiting period. This led to the development of staged surgical palliation as the first-line surgical therapy for HLHS. Recent advances in genetic engineering and xenotransplantation have provided the potential to replicate the excellent results of neonatal cardiac allotransplantation while eliminating wait-list-associated mortality through genetically modified pig-to-human neonatal cardiac xenotransplantation. The elimination of the major pig antigens in addition to the immature B-cell response in neonates allows for the potential to induce B-cell tolerance. Additionally, the relatively mature neonatal T-cell response could be reduced by thymectomy at the time of operation combined with donor-specific pig thymus transplantation to "reprogram" the host's T-cells to recognize the xenograft as host tissue. In light of the recent significantly increased graft survival of genetically-engineered pig-to-baboon cardiac xenotransplantation, we propose that now is the time to consider devoting research to advance the potential clinical application of cardiac xenotransplantation as a treatment option for patients with HLHS. Employing cardiac xenotransplantation could revolutionize therapy for complex congenital heart defects and open a new chapter in the field of pediatric cardiac transplantation.

Abstract
Objectives: The recent trend to optimize the efficiency of health-care systems requires objective clinical and economic data. European data on the cost of surgical procedures to repair or palliate congenital heart disease in pediatric patients are lacking. Methods: A single-center study was conducted. Bootstrap analysis of variance and bootstrap independent t test assessed the excess direct medical costs associated with minor and major complications in nine surgical procedure types, from a health-care payer perspective. Generalized linear models with log-link function and inverse Gaussian family were used to determine associated covariates with the total hospitalization cost. Descriptive statistics show the repartition between out-of-pocket expenditures and reimbursed costs. Results: Four hundred thirty-seven patients were included. Mean hospitalization costs ranged from €11,106 (atrial septal defect repair) to €33,865 (Norwood operation). Operations with major complications yielded excess costs compared to operations with no complications, ranging from €7,105 (+65.2%) for a truncus arteriosus repair to €27,438 (+251.7%) for a tetralogy of Fallot repair. Differences in costs were limited between operations with minor versus no complications. Age at procedure, intensive care unit stay, procedure risk category, reintervention, and postoperative mechanical circulatory support were associated with higher total hospitalization costs. Out-of-pocket expenditures represented 6% of total hospitalization costs. Conclusion: Operations with major complications yield excess costs, compared to operations with minor or no complications. Cost data and attribution are important to improve clinical practice in a cost-effective manner. The health-care system benefits from strategies and technological advancements that have an impact on modifiable cost-affecting parameters.

Abstract
Prematurity increases pre- and postoperative mortality in children with congenital heart disease. There are no large, multicentered, studies that have evaluated this relation specifically in neonates with hypoplastic left heart syndrome (HLHS). We sought to determine the impact of gestational age (GA) on survival to Stage 1 palliation surgery and hospital discharge in infants with HLHS. We reviewed data from 1,913 neonates with HLHS born at or transferred to a Vermont Oxford Network expanded member hospital in the United States from 2009 to 2014. Demographic, diagnostic, and surgical codes, and outcome data within the Vermont Oxford Network database were used to determine the effect of GA and birth weight on survival to Stage 1 palliation surgery and hospital discharge. Risk models were developed controlling for common confounders to determine the relative risk of GA on the observed outcomes. These data demonstrate that, when compared with 39-week infants, those born at earlier GA were less likely to survive until surgery; <34 weeks adjusted risk ratio (ARR) for survival: 0.47 (95% confidence interval 0.37 to 0.60), 34 to 35 weeks ARR 0.73 (0.62 to 0.87), and 36 to 37 weeks ARR 0.88 (0.83 to 0.94). Higher GA also positively correlated with survival to hospital discharge, although there was no difference in 34 to 35-week infants and 36 to 37-week infants. In conclusion, these data show that GA was an independent risk factor for survival to Stage 1 palliation surgery and survival to hospital discharge. However, there is no significant difference in survival to hospital discharge between infants born in 34 to 37 weeks gestation.

Abstract
OBJECTIVE The objective of this study was to evaluate the cost effectiveness of tissue engineered bovine tissue pericardium scaffold (CardioCel) for the repair of congenital heart defects in comparison with surgery using xenogeneic, autologous, and synthetic patches over a 40-year time horizon from the perspective of the UK National Health Service. METHODS A six-state Markov state-transition model to model natural history of disease and difference in the interventional effect of surgeries depending on patch type implanted. Patches differed regarding their probability of re-operation due to patch calcification, based on a systematic literature review. Transition probabilities were based on the published literature, other clinical inputs were based on UK registry data, and cost data were based on UK sources and the published literature. Incremental cost-effectiveness ratio (ICER) was determined as incremental costs per quality adjusted life years (QALY) gained. We used a 40-year analytic time-horizon and adopted the payer perspective. Comprehensive sensitivity analyses were performed. RESULTS According to the model predictions, CardioCel was associated with reduced incidence of re-operation, increased QALY, and costs savings compared to all other patches. Cost savings were greatest compared to synthetic patches. Estimated cost savings associated with CardioCel were greatest within atrioventricular septal defect repair and lowest for ventricular septal defect repair. Based on our model, CardioCel relative risk for re-operations is 0.938, 0.956and 0.902 relative to xenogeneic, autologous, and synthetic patches, respectively. CONCLUSION CardioCel was estimated to increase health benefits and save cost when used during surgery for congenital heart defects instead of other patches.

Abstract
When shared decision making breaks down and parents and medical providers have developed entrenched and conflicting views, ethical frameworks are needed to find a way forward. This article reviews the evolution of thought about the best interest standard and then discusses the advantages of the harm principle (HP) and the zone of parental discretion (ZPD). Applying these frameworks to parental refusals in situations of complexity and uncertainty presents challenges that necessitate concrete substeps to analyze the big picture and identify key questions. I outline and defend a new decision-making tool that includes three parts: identifying the nature of the disagreement, checklists for key elements of the HP and ZPD, and a "think list" of specific questions designed to enhance use of the HP and ZPD in clinical decision making. These tools together will assist those embroiled in complex disagreements to disentangle the issues to find a path to resolution.

Abstract
Hypoplastic left heart syndrome (HLHS) is a highly resource-intensive diagnosis. Geographic variation in cost and length of stay (LOS) in HLHS is not well described. Neonates diagnosed with HLHS between 2000 and 2012 were identified using the Kids' Inpatient Database. Hospitalizations were stratified into two groups: (1) birth and (2) secondary. United States regional differences in hospital charges and LOS were compared using adjusted linear regression. Of 2431 birth hospitalizations, 449 neonates (18.5%) died while inpatient and mortality rates differed by region (p = 0.02). After birth, 40.5% (n = 985) of neonates were transferred; transfers were most common in the Midwest (p < 0.0001). Adjusted average LOS was shortest in the West and longest in the South (26.1 days; 95% CI 24.0, 35.1 vs. 34.9 days; 95% CI 31.8, 38.1). Average adjusted charges were lowest in the Northeast ($324,600; 95% CI $271,400, $377,900) and highest in the West ($400,500; 95% CI $346,700, $454,300, p = 0.05). Among 1895 secondary hospitalizations, 24.9% of neonates died as inpatients, and the average adjusted LOS was shortest in the West (26.8 days; 95% CI 23.9, 29.7) and longest in the South (38.5 days; 95% CI 34.4, 42.4). Average adjusted charges were lowest in the Northeast ($326,900; 95% CI $270,700, $383,100) and highest in the South ($505,900; 95% CI $450,200, $561,500, p < 0.0001). Significant geographic variations in mortality, LOS, and hospital charges exist in care of US HLHS neonates. Reducing variation in care should remain a priority in national quality efforts in congenital heart disease.

Abstract
BACKGROUND Data regarding health care resource utilization (HRU) in early childhood among children with congenital heart disease (CHD) are scarce. Therefore, we sought to describe the extent of HRU incurred among children with CHD in the first 5 years of life. METHODS This population-based retrospective cohort study included all children born between January 2005 and March 2014 in Alberta, Canada. We linked inpatient, outpatient, practitioner claims, and drug dispensing databases with vital statistics (birth and death registries). RESULTS In the first year of life, the cumulative hospitalization rate per 100 children was 335 (95% confidence interval: 312-360) for single ventricle (SV) children, 200 (194-206) for moderate-complex CHD, and 152 (149-156) for simple CHD vs 109 (108-109) among children without CHD (P < 0.001). The ambulatory-care visit rate per 100 children was 4871 (4780-4963) for SV, 2278 (2258-2299) for moderate-complex, and 1416 (1405-1426) for simple CHD vs 246 (246-247) for children without CHD (P < 0.001). The rates of physician claims and drug dispensing also demonstrated similar patterns. The median total hospitalization length of stay during the first year of life was 54 days (interquartile range: 26-95) in SV, 15 (4-39) in moderate-complex, and 6 (2-26) in simple CHD compared with 2 (1-3) among children without CHD (P < 0.001). These differences remained throughout the first 5 years of life, with children with CHD having consistently higher hospitalization rates and emergency department visit rates in every year of age compared with children without CHD. CONCLUSIONS Cumulative HRU is high among children with CHD in the first 5 years of life and increases with increasing CHD severity. Improving survival of SV lesions will require increasing resource allocation to this group.

Abstract
OBJECTIVE Prenatal diagnosis of congenital heart disease (CHD) is associated with improved clinical outcomes, yet its impact on the cost of hospitalization is not well described. We hypothesized that prenatal diagnosis of complete transposition of the great arteries (d-TGA) results in lower total hospital costs compared with postnatal diagnosis. METHODS Retrospective analysis of infants with d-TGA repaired at our center from July 2006 to 2014. Total charges from initial hospitalization until discharge were converted to costs using the cost-to-charge ratio and then converted into 2016 dollars using the consumer price index. A direct cost comparison from the hospital perspective was performed between groups. A secondary analysis included the cost of prenatal diagnosis. RESULTS Thirty-three infants with d-TGA were identified; 8 with and 25 without prenatal diagnosis. There was no difference in baseline characteristics. Mean direct cost of hospitalization was higher in infants without prenatal diagnosis ($108 014 ± $51 305 vs $88 305 ± $22 896, P = .31). On secondary analysis, the cost of prenatal diagnosis was negligible compared with total hospital cost. CONCLUSIONS Total cost of initial hospitalization was higher for infants without prenatal diagnosis of d-TGA. Prenatal diagnosis not only improves clinical outcomes but may also be cost saving in the current era of increasing health care costs.

Cost Variation Across Centers for the Norwood Operation. Ann Thorac Surg 2017; 105:851-856. [PMID: 29223416 DOI: 10.1016/j.athoracsur.2017.09.001] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2017] [Revised: 08/11/2017] [Accepted: 09/01/2017] [Indexed: 11/24/2022]
Abstract
BACKGROUND The Norwood operation is associated with high health care utilization, and prior studies reported substantial variability in Norwood costs across centers. However, specific factors driving this cost variation are unclear. We assessed center variability in Norwood costs and underlying mechanisms in a multicenter cohort. METHODS Clinical data from the Pediatric Heart Network Single Ventricle Reconstruction trial were linked with cost data from the Children's Hospital Association Inpatient Essentials database. Center variation was assessed by modeling Norwood costs adjusted for baseline patient characteristics, and the relationship with complications, length of stay (LOS), and specific cost categories was examined. Patients undergoing transplantation or stage 2 palliation during the Norwood admission were excluded. RESULTS Nine centers (332 patients) were included. Adjusted mean cost/case varied 4.6-fold across centers (range: $50,559 to $230,851, p < 0.001). In addition, variation was found across centers in the adjusted mean number of complications/case (2.6-fold variation) and adjusted mean LOS/case (1.9-fold variation). Differences in complications explained 63% of the cost variation across centers. After accounting for complications, differences in LOS explained 66% of the remaining cost variation. Seven specific complications were found to occur more frequently at high-cost centers: pleural effusion, seizures, wound infection, thrombus, liver dysfunction, sepsis, necrotizing enterocolitis (all p < 0.001). With regard to types of cost, room and board/supplies and laboratory costs were the primary drivers of cost variation across centers. CONCLUSIONS This study identified several factors associated with center variation in Norwood costs, which may be targeted in subsequent initiatives aimed at both improving quality of care and reducing costs.

Abstract
BACKGROUND Resource utilization in congenital heart surgery is typically assessed using administrative data sets. Recent analyses have called into question the accuracy of coding of cases in administrative data; however, it is unclear whether miscoding impacts assessment of associated resource use. METHODS We merged data coded within both an administrative data set and clinical registry on children undergoing heart surgery (2004-2010) at 33 hospitals. The impact of differences in coding of operations between data sets on reporting of postoperative length of stay (PLOS) and total hospital costs associated with these operations was assessed. RESULTS For each of the eight operations of varying complexity evaluated (total n = 57,797), there were differences in coding between data sets, which translated into differences in the reporting of associated resource utilization for the cases coded in either data set. There were statistically significant differences in PLOS and cost for seven of the eight operations, although most PLOS differences were relatively small with the exception of the Norwood operation and truncus repair (differences of two days, P < .001). For cost, there was a >5% difference for three of the eight operations and >10% difference for truncus repair (US$10,570; P < .01). Grouping of operations into categories of similar risk appeared to mitigate many of these differences. CONCLUSION Differences in coding of cases in administrative versus clinical registry data can translate into differences in assessment of associated PLOS and cost for certain operations. This may be minimized through evaluating larger groups of operations when using administrative data or using clinical registry data to accurately identify operations of interest.

Abstract
We estimated the inpatient resource use for a Fontan patient from birth to adulthood and explored factors that might induce cost differences (2014 US dollar). Inpatient costing records from 4 hospitals with greatest numbers of Fontan patients in Australia and New Zealand were linked with the Fontan registry database. Inpatient records between July 1995 and September 2014 for 420 Fontan patients were linked, and the most frequent primary diagnoses were hypoplastic left heart syndrome (20.7%), tricuspid atresia (19.7%), and double inlet left ventricle (17.1%). The mean hospital cost for a Fontan patient from birth to 18 years of age was estimated to be $390,601 (95% confidence interval [CI] $264,703 to $516,499), corresponding to 164 (95% CI 98 to 231) inpatient days. The cost incurred from birth through to Fontan completion (the staged procedures period) was $219,482 (95% CI $202,410 to $236,553) and the cost thereafter over 15 years was $146,820 (95% CI $44,409 to $249,231), corresponding to 82 (95% CI 72 to 92) and 65 (95% CI 18 to 112) inpatient days, respectively. Costs were higher in male and hypoplastic left heart syndrome patients in the staged procedures period (p <0.001). Having fenestration was associated with higher costs in the staged procedures period (p <0.001) and lower cost after Fontan over 15 years (p = 0.66). In conclusion, patients with single ventricle congenital heart disease continue to demand considerable inpatient resources after the staged procedures period. Over 40% of the pediatric hospital costs for Fontan patients were estimated to occur after the last planned surgery.

Abstract
In an era of ongoing need for research to enable evidence-based care for the expanding population with congenital heart disease (CHD), economic fluctuations have impacted research funding. We characterize trends in NIH-funded CHD research from 2005 to 2015. We searched the NIH RePORTER database from 2005 to 2015 using the terms "congenital heart" and "cardiac morphogenesis". Projects were characterized by year, institute, mechanism, costs, type and topic, and funding trends were analyzed. From 2005 to 2015, NIH funded 633 CHD research projects with total costs of $991 million. The National Heart, Lung, and Blood Institute funded 83% of CHD projects (528, $857 million). The R01 mechanism was used for 45% of projects (288, $421 million). Projects were 70% basic/early translational research, 27% clinical research, and 3% both. Cardiac developmental biology was the most common topic (52%), followed by technology/therapy development (15%), and diagnosis/management (12%). The total number of CHD projects ranged from 153 to 221 per year (30-58 new projects/year), and costs per year ranged from $58 to $116 million. The number of projects and total costs increased until 2012, but decreased again thereafter. CHD research did not experience as much erosion as overall NIH purchasing power; in constant dollars, CHD research funding levels in 2015 were $12 million higher than those in 2005. The NIH supported a diverse portfolio of CHD projects from 2005 to 2015. Support of CHD research projects trended upward until 2012, but declined thereafter due to fiscal austerity measures.

Resource Utilization Associated with Extracardiac Co-morbid Conditions Following Congenital Heart Surgery in Infancy. Pediatr Cardiol 2017; 38:1065-1070.

Abstract
Congenital heart disease (CHD) is often associated with chronic extracardiac co-morbid conditions (ECC). The presence of ECC has been associated with greater resource utilization during the operative period; however, the impact beyond hospital discharge has not been described. This study sought to understand the scope of chronic ECC in infants with CHD as well as to describe the impact of ECC on resource utilization after discharge from the index cardiac procedure. IRB approved this retrospective study of infants <1 year who had cardiac surgery from 2006 and 2011. Demographics, diagnoses, procedures, STAT score, and ECC were extracted from the medical record. Administrative data provided frequency of clinic and emergency room visits, admissions, cumulative hospital days, and hospital charges for 2 years after discharge from the index procedure. Data were compared using Mann-Whitney Rank Sum Test with p < 0.05 considered significant. ECC occurred in 55% (481/876) of infants. Median STAT score was higher in the group with ECC (3 vs. 2, p < 0.001). Resource utilization after discharge from the index procedure as defined by median hospital charges (78 vs. 10 K, p < 0.001 and unplanned hospital days 4 vs. 0, p < 0.001) was higher in those with ECC, and increased with the greater number of ECC, even after accounting for surgical complexity. STAT score and the presence of multiple ECC were associated with higher resource utilization following the index cardiac surgical procedure. These data may be helpful in deciding which children might benefit from a cardiac complex care program that partners families and providers to improve health and decrease healthcare costs.

Abstract
The few studies evaluating data on resource utilisation following the Fontan operation specifically are outdated. We sought to evaluate resource utilisation and factors associated with increased resource use after the Fontan operation in a contemporary, large, multi-institutional cohort. This retrospective cohort study of children who had the Fontan between January, 2004 and June, 2013 used the Pediatric Health Information Systems Database. Generalised linear regression analyses evaluated factors associated with resource use. Of 2187 Fontan patients included in the study, 62% were males. The median age at Fontan was 3.2 years (inter-quartile range (IQR): 2.6-3.8). The median length of stay following the Fontan was 9 days (IQR: 7-14). The median costs and charges in 2012 dollars for the Fontan operation were $93,900 (IQR: $67,800-$136,100) and $156,000 (IQR: $112,080-$225,607), respectively. Postoperative Fontan mortality (30 days) was 1% (n=21). Factors associated with increased resource utilisation included baseline and demographic factors such as region, race, and renal anomaly, factors at the bidirectional Glenn such as seizures, valvuloplasty, and surgical volume, number of admissions between the bidirectional Glenn and the Fontan, and factors at the Fontan such as surgical volume and age at Fontan. The most strongly associated factors for both increased Fontan length of stay and increased Fontan charges were number of bidirectional Glenn to Fontan admissions (p<0.001) and Fontan surgical volume per year (p<0.001). As patient characteristics and healthcare-related delivery variables accounted for most of the factors predicting increased resource utilisation, changes should target healthcare delivery factors to reduce costs in this resource-intensive population.

Abstract
Hypoplastic left heart syndrome (HLHS) was a uniformly fatal diagnosis before 1983, when surgical treatment was first undertaken with the Norwood I operation as the first of 3-staged operations. Since then, operative survival rate of stage I has risen from 53% to over 90% in the current era, not only thanks to technical advances in surgery but also through prenatal diagnosis and imaging, enhanced cardiopulmonary bypass technology, better perioperative intensive care, and closer interstage monitoring. The improvements in patient outcomes achieved through rigorous multidisciplinary teamwork have come at a tremendous cost in manpower and resources, making HLHS still a challenge to all congenital heart programs, established or emerging. We review the various surgical steps to treat HLHS and their current expected outcomes, and put into perspective cost considerations compared to other more “simple” congenital heart defects.
