Abstract
BACKGROUND AND OBJECTIVES Health disparities are pervasive in pediatrics. We aimed to describe disparities among patients who are likely to be cared for in the PICU and delineate how sociodemographic data are collected and categorized. METHODS Using MEDLINE as a data source, we identified studies which included an objective to assess sociodemographic disparities among PICU patients in the United States. We created a review rubric, which included methods of sociodemographic data collection and analysis, outcome and exposure variables assessed, and study findings. Two authors reviewed every study. We used the National Institute on Minority Health and Health Disparities Research Framework to organize outcome and exposure variables. RESULTS The 136 studies included used variable methods of sociodemographic data collection and analysis. A total of 30 of 124 studies (24%) assessing racial disparities used self- or parent-identified race. More than half of the studies (52%) dichotomized race as white and "nonwhite" or "other" in some analyses. Socioeconomic status (SES) indicators also varied; only insurance status was used in a majority of studies (72%) evaluating SES. Consistent, although not uniform, disadvantages existed for racial minority populations and patients with indicators of lower SES. The authors of only 1 study evaluated an intervention intended to mitigate health disparities. Requiring a stated objective to evaluate disparities aimed to increase the methodologic rigor of included studies but excluded some available literature. CONCLUSIONS Variable, flawed methodologies diminish our understanding of disparities in the PICU. Meaningfully understanding and addressing health inequity requires refining how we collect, analyze, and interpret relevant data.

Racial and Ethnic Variation in ECMO Utilization and Outcomes in Pediatric Cardiac ICU Patients. JACC. ADVANCES 2023; 2:100634. [PMID: 38938717 PMCID: PMC11198441 DOI: 10.1016/j.jacadv.2023.100634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 06/15/2023] [Accepted: 07/26/2023] [Indexed: 06/29/2024]
Abstract
Background Previous studies have reported racial disparities in extracorporeal membrane oxygenation (ECMO) utilization in pediatric cardiac patients. Objectives The objective of this study was to determine if there was racial/ethnic variation in ECMO utilization and, if so, whether mortality was mediated by differences in ECMO utilization. Methods This is a multicenter, retrospective cohort study of the Pediatric Cardiac Critical Care Consortium clinical registry. Analyses were stratified by hospitalization type (medical vs surgical). Logistic regression models were adjusted for confounders and evaluated the association between race/ethnicity with ECMO utilization and mortality. Secondary analyses explored interactions between race/ethnicity, insurance, and socioeconomic status with ECMO utilization and mortality. Results A total of 50,552 hospitalizations from 34 hospitals were studied. Across all hospitalizations, 2.9% (N = 1,467) included ECMO. In medical and surgical hospitalizations, Black race and Hispanic ethnicity were associated with severity of illness proxies. In medical hospitalizations, race/ethnicity was not associated with the odds of ECMO utilization. Hospitalizations of other race had higher odds of mortality (adjusted odds ratio [aOR]: 1.61; 95% CI: 1.22-2.12; P = 0.001). For surgical hospitalizations, Black (aOR: 1.24; 95% CI: 1.02-1.50; P = 0.03) and other race (aOR: 1.50; 95% CI: 1.17-1.93; P = 0.001) were associated with higher odds of ECMO utilization. Hospitalizations of Hispanic patients had higher odds of mortality (aOR: 1.31; 95% CI: 1.03-1.68; P = 0.03). No significant interactions were demonstrated between race/ethnicity and socioeconomic status indicators with ECMO utilization or mortality. Conclusions Black and other races were associated with increased ECMO utilization during surgical hospitalizations. There were racial/ethnic disparities in outcomes not explained by differences in ECMO utilization. Efforts to mitigate these important disparities should include other aspects of care.

Trends in Contemporary Use of Ventricular Assist Devices in Children Awaiting Heart Transplantation and Their Outcomes by Race/Ethnicity. ASAIO J 2023; 69:210-217. [PMID: 35438653 DOI: 10.1097/mat.0000000000001747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/02/2023] Open
Abstract
This retrospective study included children aged ≤18 years who had durable ventricular assist devices (VADs) as a bridge to transplantation from the United Network Organ Sharing (UNOS) database between 2011 and 2020. We evaluated 90 day waitlist mortality and 1 year posttransplant mortality after VAD implantation in children stratified by race/ethnicity: Black, White, and Others. The VAD was used in a higher proportion of Black children listed for heart transplantation (HT) (26%) versus Other (25%) versus White (22%); p < 0.01. Black children had Medicaid health insurance coverage (67%) predominantly at the time of listing for HT. There was no significant overall difference in waitlist survival among the three groups supported with VAD at the time of listing (log-rank p = 0.4). On the other hand, the 90 day waitlist mortality after the VAD implantation at listing and while listed was the lowest among Black (6%) compared with White (13%) and Other (14%) ( p < 0.01). The multivariate regression analysis showed that Other race (hazard ratio [HR], 2.29; p < 0.01), Black race (HR, 2.13; p < 0.01), use of mechanical ventilation (HR, 1.72; p = 0.01), and Medicaid insurance (HR, 1.54; p = 0.04) were independently associated with increased 1 year posttransplant mortality. In conclusion, Black children had more access to durable VAD support than White children. The 90 day waitlist mortality was significantly lower in Black children compared with White and Other after VAD implantation. However, Black and Other racial/ethnic children with VAD at transplant had higher 1 year posttransplant mortality than White children. Future studies to elucidate the reasons for these disparities are needed.

Abstract
Supraventricular tachycardia (SVT) is a common pediatric arrhythmia. The objective of this investigation was to investigate the existence and degree of the health disparities in the treatment of pediatric patients with supraventricular tachycardia based on sociodemographic factors. This was retrospective cohort study at a large academic medical center including children ages 5-18 years old diagnosed with SVT. Patients with congenital heart disease and myocarditis were excluded. Initial treatment and ultimate treatment with either medical management or ablation were determined. The odds of having an ablation procedure were determined based on patient age, sex, race, ethnicity, and insurance status. There was a larger portion of non-White patients (p = 0.033) within the cohort that did not receive an ablation during the study period. Patients that were younger, female, American Indian/Alaskan Native, unknown race, and had missing insurance information were less likely to receive ablation therapy during the study period. In this single center, regional evaluation, we demonstrated that disparities in the treatment of pediatric SVT are present based on multiple patient sociodemographic factors. This study adds evidence to the presence of inequities in health care delivery across pediatric populations.

Abstract
When resources in a society are dispersed unevenly, generally through allocation standards, distinct patterns emerge along lines of socially defined categories of people. Power, religion, kinship, prestige, race, ethnicity, gender, age, sexual orientation, and class all play a role in determining who has access to social goods in society. In most cases, social inequality refers to a lack of equality of outcome, but it can also refer to a lack of equality of access to opportunity. Unfortunately, health care is not immune to these social disparities and/or inequalities. These health care disparities in interventional cardiology were recently brought to the forefront by the Society for Cardiovascular Angiography and Interventions (SCAI) as a major focus of 2020-2021. In a recent publication, unique factors leading to disparities were reported to exist among the subsections of interventional cardiology. The congenital heart disease council of SCAI created a task force to further investigate the unique challenges and disparities impacting the practice of congenital heart disease and pediatric cardiology.

Abstract
Congenital heart disease (CHD) and prematurity are the leading causes of infant mortality in the United States. Importantly, the combination of prematurity and CHD results in a further increased risk of mortality and significant morbidity. The key factors in these adverse outcomes are not well understood, but likely include maternal-fetal environment, perinatal and neonatal elements, and challenging postnatal care. Preterm neonates with CHD are born with "double jeopardy": not only do they experience challenges related to immaturity of the lungs, brain, and other organs, but they also must undergo treatment for cardiac disease. The role of the neonatologist caring for preterm infants with CHD has changed with the evolution of the field of pediatric cardiac critical care. Increasingly, neonatologists invested in the cardiovascular care of the newborn with CHD engage at multiple stages in their course, including fetal consultation, delivery room management, preoperative care, and postoperative treatment. A more comprehensive understanding of prematurity and CHD may inform clinical practice and ultimately improve outcomes in preterm infants with CHD. In this review, we discuss the current evidence surrounding neonatal and cardiac outcomes in preterm infants with CHD; examine the prenatal, perinatal, and postnatal factors recognized to influence these outcomes; identify knowledge gaps; consider research and clinical opportunities; and highlight the ways in which a neonatologist can contribute to the care of preterm infants with CHD.

Abstract
Despite the overall improvement in life expectancy of patients living with congenital heart disease (congenital HD), disparities in morbidity and mortality remain throughout the lifespan. Longstanding systemic inequities, disparities in the social determinants of health, and the inability to obtain quality lifelong care contribute to poorer outcomes. To work toward health equity in populations with congenital HD, we must recognize the existence and strategize the elimination of inequities in overall congenital HD morbidity and mortality, disparate health care access, and overall quality of health services in the context of varying social determinants of health, systemic inequities, and structural racism. This requires critically examining multilevel contributions that continue to facilitate health inequities in the natural history and consequences of congenital HD. In this scientific statement, we focus on population, systemic, institutional, and individual‐level contributions to health inequities from prenatal to adult congenital HD care. We review opportunities and strategies for improvement in lifelong congenital HD care based on current public health and scientific evidence, surgical data, experiences from other patient populations, and recognition of implicit bias and microaggressions. Furthermore, we review directions and goals for both quantitative and qualitative research approaches to understanding and mitigating health inequities in congenital HD care. Finally, we assess ways to improve the diversity of the congenital HD workforce as well as ethical guidance on addressing social determinants of health in the context of clinical care and research.

Abstract
BackgroundSocial determinants of health (SDoH) affect congenital heart disease (CHD) mortality across all forms and age groups. We sought to evaluate risk of mortality from specific SDoH stratified across CHD to guide interventions to alleviate this risk.MethodsWe searched electronic databases between January 1980 and June 2019 and included studies that evaluated occurrence of CHD deaths and SDoH in English articles. Meta-analysis was performed if SDoH data were available in >3 studies. We included race/ethnicity, deprivation, insurance status, maternal age, maternal education, single/multiple pregnancy, hospital volume, and geographic location of patients as SDoH. Data were pooled using random-effects model and outcome was reported as odds ratio (OR) with 95% confidence interval (CI).ResultsOf 17,716 citations reviewed, 65 met inclusion criteria. Sixty-three were observational retrospective studies and two prospective. Of 546,981 patients, 34,080 died. Black patients with non-critical CHD in the first year of life (Odds Ratio 1.62 [95% confidence interval 1.47–1.79], I2 = 7.1%), with critical CHD as neonates (OR 1.27 [CI 1.05-1.55], I2 = 0%) and in the first year (OR 1.68, [1.45-1.95], I2 = 0.3%) had increased mortality. Deprived patients, multiple pregnancies, patients born to mothers <18 years and with education <12 years, and patients on public insurance with critical CHD have greater likelihood of death after the neonatal period.ConclusionThis systematic review and meta-analysis found that Black patients with CHD are particularly vulnerable for mortality. Numerous SDoH that affect mortality were identified for specific time points in CHD course that may guide interventions, future research and policy.Systematic Review Registration[https://www.crd.york.ac.uk/PROSPERO/display_record.php?ID=CRD42019139466&ID=CRD42019139466], identifier [CRD42019139466].

Abstract
BACKGROUND Interstage mortality (IM) remains high for patients with single-ventricle congenital heart disease (SVCHD) in the period between Stage 1 Palliation (S1P) and Glenn operation. We sought to characterize IM. METHODS This was a descriptive analysis of 2184 patients with SVCHD discharged home after S1P from 60 National Pediatric Cardiology Quality Improvement Collaborative sites between 2008 and 2015. Patients underwent S1P with right ventricle-pulmonary artery conduit (RVPAC), modified Blalock-Taussig-Thomas shunt (BTT), or Hybrid; transplants were excluded. RESULTS IM occurred in 153 (7%) patients (median gestational age 38 weeks, 54% male, 77% white), at 88 (IQR 60,136) days of life, and 39 (IQR 17,84) days after hospital discharge; 13 (8.6%) occurred ≤ 30 days after S1P. The mortality rate for RVPAC was lower (5.2%; 59/1138) than BTT (9.1%; 65/712) and Hybrid (20.1%; 27/134). More than half of deaths occurred at home (20%) or in the emergency department (33%). The remainder occurred while inpatient at center of S1P (cardiac intensive care unit 36%, inpatient ward 5%) or at a different center (5%). Fussiness and breathing problems were most often cited as harbingers of death; distance to surgical center was the biggest barrier cited to seeking care. Cause of death was unknown in 44% of cases overall; in the subset of patients who underwent post-mortem autopsy, the cause of death remained unknown in 30% of patients, with the most common diagnosis being low cardiac output. CONCLUSIONS Most IM occurred in the outpatient setting, with non-specific preceding symptoms and unknown cause of death. These data indicate the need for research to identify occult causes of death, including arrhythmia.

Abstract
Racial disparities have been reported among pediatric patients waitlisted for and undergoing heart transplantation but have not been studied further upstream in the transplant candidate evaluation process. We retrospectively studied our single-center experience in order to investigate any potential biases in the evaluation process. Results of the heart transplant evaluation in children ≤18 years old at our institution were analyzed. Primary outcome was final disposition to waitlist or not. Race was defined by family self-identification. Descriptive and comparative statistical analyses were performed. From 2013 to 2019, 133 unique patients were referred for listing consideration. While Black patients comprised 44% of the referral population and had more markers of socioeconomic disadvantage, they comprised 43% of the patients who were listed for transplantation with no significant difference between these proportions (p = .96). Black and White patients made up a similar proportion of patients deemed too well or too ill for listing. Black patients had lower annual household income estimates and rates of household marriage. Despite identifying significant social challenges in 27 patients (18 of them Black), only five patients (3 Black and 2 White) were turned down for listing due to social barriers. While limited by the small number of patients turned down for social barriers, our transplant evaluation process does not appear to result in racial disparities in access to listing. Further studies are needed using national cohorts to explore possible racial disparities upstream from waitlisting and transplantation, such as during the referral and evaluation.

Abstract
Cardiovascular disease (CVD) remains the leading cause of death in the United States. However, percutaneous interventional cardiovascular therapies are often underutilized in Blacks, Hispanics, and women and may contribute to excess morbidity and mortality in these vulnerable populations. The Society for Cardiovascular Angiography and Interventions (SCAI) is committed to reducing racial, ethnic, and sex-based treatment disparities in interventional cardiology patients. Accordingly, each of the SCAI Clinical Interest Councils (coronary, peripheral, structural, and congenital heart disease [CHD]) participated in the development of this whitepaper addressing disparities in diagnosis, treatment, and outcomes in underserved populations. The councils were charged with summarizing the available data on prevalence, treatment, and outcomes and elucidating potential reasons for any disparities. Given the huge changes in racial and ethnic composition by age in the United States (Figure 1), it was difficult to determine disparities in rates of diagnosis and we expected to find some racial differences in prevalence of disease. For example, since the average age of patients undergoing transcatheter aortic valve replacement (TAVR) is 80 years, one may expect 80% of TAVR patients to be non-Hispanic White. Conversely, only 50% of congenital heart interventions would be expected to be performed in non-Hispanic Whites. Finally, we identified opportunities for SCAI to advance clinical care and equity for our patients, regardless of sex, ethnicity, or race.

Ann Thorac Surg 2021; 113:157-165. [PMID: 33872577 DOI: 10.1016/j.athoracsur.2021.04.008] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2020] [Revised: 03/26/2021] [Accepted: 04/05/2021] [Indexed: 11/01/2022]
Abstract
BACKGROUND Socioeconomic and racial (SER) disparities among congenital heart disease (CHD) patients may limit access to high-quality care. We characterized national SER landscape, its relationship to early outcomes, and identified interactions among determinants mitigating adverse outcome. METHODS The Pediatric Health Information System (PHIS) database queried patients (age < 26 years) with CHD between 2016-2018. ICD-10 codes were mapped to diagnostic categories for complexity adjustment. Correlational and hierarchical regression analyses identified risk-factors and characterized interactions. RESULTS N=166,599 unique admissions from 52 hospitals were identified, 58,395 having interventions. Median age was 0 years (IQR=4 years). Race/Ethnicity was predominantly White (59%), Hispanic (20%), and Black (16%). Median neighborhood household income (NHI) was $41,082, and varied among hospitals. Patient NHI had a parabolic relationship with mortality, with both higher and lower values having increased risk. Black patients had significantly higher mortality, and this relationship was potentiated by lower NHI and complexity. Length of hospital stay (LOS) was longer among Black neonates (median 51 days; IQR 93) compared to neonates of other ethnic groups (median 32 days; IQR 71), P<0.0001. Care pathways including permanent feeding tubes were also more prevalent among Black neonates (17.8%) compared to White neonates (15%), P=0.02. CONCLUSIONS Interactions among SER disparities modify CHD outcomes. Specific hospitals have more SER fragile patients, but may have developed care pathways that prolong LOS to mitigate risk among Black neonates. Adverse outcomes among SER disadvantaged patients are magnified in complex CHD, suggesting tangible benefits to targeted resource allocation and population health initiatives.

Abstract
BACKGROUND Congenital heart disease (CHD) accounts for ≈40% of deaths in US children with birth defects. Previous US data from 1999 to 2006 demonstrated an overall decrease in CHD mortality. Our study aimed to assess current trends in US mortality related to CHD from infancy to adulthood over the past 19 years and determine differences by sex and race/ethnicity. METHODS We conducted an analysis of death certificates from 1999 to 2017 to calculate annual CHD mortality by age at death, race/ethnicity, and sex. Population estimates used as denominators in mortality rate calculations for infants were based on National Center for Health Statistics live birth data. Mortality rates in individuals ≥1 year of age used US Census Bureau bridged-race population estimates as denominators. We used joinpoint regression to characterize temporal trends in all-cause mortality, mortality resulting directly attributable to and related to CHD by age, race/ethnicity, and sex. RESULTS There were 47.7 million deaths with 1 in 814 deaths attributable to CHD (n=58 599). Although all-cause mortality decreased 16.4% across all ages, mortality resulting from CHD declined 39.4% overall. The mean annual decrease in CHD mortality was 2.6%, with the largest decrease for those >65 years of age. The age-adjusted mortality rate decreased from 1.37 to 0.83 per 100 000. Males had higher mortality attributable to CHD than females throughout the study, although both sexes declined at a similar rate (≈40% overall), with a 3% to 4% annual decrease between 1999 and 2009, followed by a slower annual decrease of 1.4% through 2017. Mortality resulting from CHD significantly declined among all races/ethnicities studied, although disparities in mortality persisted for non-Hispanic Blacks versus non-Hispanic Whites (mean annual decrease 2.3% versus 2.6%, respectively; age-adjusted mortality rate 1.67 to 1.05 versus 1.35 to 0.80 per 100 000, respectively). CONCLUSIONS Although overall US mortality attributable to CHD has decreased over the past 19 years, disparities in mortality persist for males in comparison with females and for non-Hispanic Blacks in comparison with non-Hispanic Whites. Determining factors that contribute to these disparities such as access to quality care, timely diagnosis, and maintenance of insurance will be important moving into the next decade.

Abstract
OBJECTIVE Prior studies demonstrate an association between nonwhite race/ethnicity, insurance status, and mortality after pediatric congenital heart surgery. The influence of severity of illness on that association is unknown. We examined the relationship between race/ethnicity, severity of illness, and mortality in congenital cardiac surgery, and whether severity of illness is a mechanism by which nonwhite patients experience increased surgical mortality. METHODS We performed a retrospective cohort study of children younger than age 18 years old undergoing cardiac surgery admitted to the intensive care unit (n = 40,545) between 2009 and 2016 from the Virtual Pediatric Systems (VPS, LLC, Los Angeles, Calif) database. Multivariate regression models were constructed to examine the role of severity of illness as a mediator between race/ethnicity and mortality in children undergoing cardiac surgery. RESULTS In multivariate models examining severity of illness scores, African-American patients had statistically significant higher severity of illness scores when compared with their white counterparts. In multivariate models of intensive care unit mortality after adjustment for covariates, African-American patients had a higher odds of postoperative mortality (odds ratio, 1.40, 95% confidence interval, 1.04-1.89) when compared with white children. This increased odds of mortality was mediated through higher severity of illness, because adjustment for severity of illness removed this survival disadvantage for black patients. CONCLUSIONS Although African-American children undergoing cardiac surgery had higher postoperative mortality, this survival difference appears to be mediated via severity of illness. Preoperative and intraoperative factors may be drivers for this survival disparity.

Abstract
BACKGROUND Congenital heart defects (CHDs), the most common type of birth defect in the United States, are increasing in prevalence in the general population. Though CHD prevalence at birth has been well described in the United States at about 1%, little is known about long-term survival and prevalence of CHDs beyond childhood. This study aimed to estimate the prevalence of CHDs among adolescents and adults in Colorado. METHODS The prevalence of CHDs among adolescents and adults residing in Colorado during 2011 to 2013 was estimated using log-linear capture-recapture methods to account for incomplete case ascertainment. Five case-finding data sources were used for this analysis including electronic health record data from 4 major health systems and a state-legislated all payer claims database. RESULTS Twelve thousand two hundred ninety-three unique individuals with CHDs (2481 adolescents and 9812 adults) were identified in one or more primary data sources. We estimated the crude prevalence of CHDs in adolescents and adults in Colorado to be 3.22 per 1000 individuals (95% CI 3.19-3.53). After accounting for incomplete case ascertainment, the final capture-recapture model yielded an estimated total adolescent and adult CHD population of 23,194 (95% CI 22,419-23,565) and an adjusted prevalence of 6.07 per 1000 individuals (95% CI 5.86-6.16), indicating 47% of the cases in the catchment area were not identified in the case-identifying data sources. CONCLUSION This statewide study yielded new information on the prevalence of CHDs in adolescents and adults. These high prevalence rates underscore the need for additional specialized care facilities for this population with CHDs.

Abstract
PURPOSE To investigate ethnic differences in mortality for infants with congenital heart defects (CHDs) undergoing cardiac surgery or interventional catheterisation. DESIGN Observational study of survival to age 1 year using linked records from routine national paediatric cardiac surgery and intensive care audits. Mortality risk was investigated using multivariable Poisson models with multiple imputation. Predictors included sex, ethnicity, preterm birth, deprivation, comorbidities, prenatal diagnosis, age and weight at surgery, preprocedure deterioration and cardiac diagnosis. SETTING All paediatric cardiac surgery centres in England and Wales. PATIENTS 5350 infants with CHDs born from 2006 to 2009. MAIN OUTCOME MEASURE Survival at age 1 year. RESULTS Mortality was 83.9 (95% CI 76.3 to 92.1) per 1000 infants, with variation by ethnic group. Compared with those of white ethnicity, infants in British Asian (Indian, Pakistani and Bangladeshi) and 'all other' (Chinese, mixed and other) categories experienced significantly higher mortality by age 1 year (relative risk [RR] 1.52[95% CI 1.19 to 1.95]; 1.62[95% CI 1.20 to 2.20], respectively), specifically during index hospital admission (RR 1.55 [95% CI 1.07 to 2.26]; 1.64 [95% CI 1.05 to 2.57], respectively). Further predictors of mortality included non-cardiac comorbidities, prenatal diagnosis, older age at surgery, preprocedure deterioration and cardiac diagnosis. British Asian infants had higher mortality risk during elective hospital readmission (RR 1.86 [95% CI 1.02 to 3.39]). CONCLUSIONS Infants of British Asian and 'all other' non-white ethnicity experienced higher postoperative mortality risk, which was only partly explained by socioeconomic deprivation and access to care. Further investigation of case-mix and timing of risk may provide important insights into potential mechanisms underlying ethnic disparities.

Am J Obstet Gynecol MFM 2019; 1:100036.

Abstract
BACKGROUND Women with single ventricle cardiac physiologic condition who have undergone Fontan procedures are surviving well into reproductive age and historically have been discouraged from pregnancy, despite the paucity of data regarding maternal and neonatal outcomes. OBJECTIVE Our primary objective was to investigate, in a large cohort, the maternal and neonatal outcomes of pregnant women who have undergone the Fontan procedure and to understand maternal and neonatal sequelae of their pregnancies. STUDY DESIGN This single-center retrospective cohort study involves pregnant women with a Fontan palliation who delivered at UCLA Medical Center over a 10-year period (2007-2017). All pregnancies were evaluated for differences in maternal and neonatal characteristics. RESULTS We identified 37 distinct pregnancies in 24 women with a Fontan procedure. The physiologic pregnancy-related increase in cardiac output is blunted substantially in Fontan circulation. Third-trimester cardiac index positively correlated to birthweight z-score (R2=0.48; P=.038) but not to small for gestational age (R2=0.13; P=.339). The most common cardiac complications in pregnancies of >24 weeks gestation were sustained arrhythmia (37.5%) and decompensated heart failure (21%). The 37 pregnancies comprised 25 live births (67.6%), 1 fetal death (2.7%), 9 spontaneous abortions (24%), and 2 pregnancy terminations (5.4%). Of the live births, 60% were preterm at an average gestational age of 34.9±3.7 weeks. Newborn infants were delivered via cesarean in 53%, operative vaginal delivery in 28%, and spontaneous vaginal delivery in 20%. Forty percent of neonates were born small (<10th percentile) for gestational age; 44.0% of all neonates were admitted to the neonatal intensive care unit. CONCLUSION Women with a single ventricle and Fontan circulation can have a successful pregnancy, although they are at increased risk for arrhythmias and heart failure. The decreased cardiac reserve in these pregnancies blunts the normal increase in maternal cardiac output, which is associated with preterm delivery and small-for-gestational-age neonates. Further studies are needed to determine to what extent the impaired rise in maternal cardiac output reduces uteroplacental perfusion, placental exchange, fetal growth, and onset of parturition.

Abstract
BACKGROUND Congenital heart surgery has improved the survival of patients with even the most complex defects, but the long-term survival after these procedures has not been fully described. OBJECTIVES The purpose of this study was to evaluate the long-term survival of patients (age <21 years) who were operated on for congenital heart defects (CHDs). METHODS This study used the Pediatric Cardiac Care Consortium data, a U.S.-based, multicenter registry of pediatric cardiac surgery. Survival analysis included 35,998 patients who survived their first congenital heart surgery at <21 years of age and had adequate identifiers for linkage with the National Death Index through 2014. Survival was compared to that in the general population using standardized mortality ratios (SMRs). RESULTS After a median follow-up of 18 years (645,806 person-years), 3,191 deaths occurred with an overall SMR of 8.3 (95% confidence interval [CI]: 8.0 to 8.7). The 15-year SMR decreased from 12.7 (95% CI: 11.9 to 13.6) in the early era (1982 to 1992) to 10.0 (95% CI: 9.3 to 10.8) in the late era (1998 to 2003). The SMR remained elevated even for mild forms of CHD such as patent ductus arteriosus (SMR 4.5) and atrial septal defects (SMR 4.9). The largest decreases in SMR occurred for patients with transposition of great arteries (early: 11.0 vs. late: 3.8; p < 0.05), complete atrioventricular canal (31.3 vs. 15.3; p < 0.05), and single ventricle (53.7 vs. 31.3; p < 0.05). CONCLUSIONS In this large U.S. cohort, long-term mortality after congenital heart surgery was elevated across all forms of CHD. Survival has improved over time, particularly for severe defects with significant changes in their management strategy, but still lags behind the general population.

Best KE, Vieira R, Glinianaia SV, Rankin J. Socio-economic inequalities in mortality in children with congenital heart disease: A systematic review and meta-analysis. Paediatr Perinat Epidemiol 2019; 33:291-309. [PMID: 31347722 DOI: 10.1111/ppe.12564] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Revised: 05/02/2019] [Accepted: 05/27/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND The impact of socio-economic status (SES) on congenital heart disease (CHD)-related mortality in children is not well established. OBJECTIVES We aimed to systematically review and appraise the existing evidence on the association between SES (including poverty, parental education, health insurance, and income) and mortality among children with CHD. DATA SOURCES Seven electronic databases (Medline, Embase, Scopus, PsycINFO, CINAHL, ProQuest Natural, and Biological Science Collections), reference lists, citations, and key journals were searched. STUDY SELECTION AND DATA EXTRACTION We included articles reporting original research on the association between SES and mortality in children with CHD if they were full papers published in the English language and regardless of (a) timing of mortality; (b) individual or area-based measures of SES; (c) CHD subtype; (d) age at ascertainment; (e) study period examined. Screening for eligibility, data extraction, and quality appraisal were performed in duplicate. SYNTHESIS Meta-analyses were performed to estimate pooled ORs for in-hospital mortality according to health insurance status. RESULTS Of 1388 identified articles, 28 met the inclusion criteria. Increased area-based poverty was associated with increased odds/risk of postoperative (n = 1), neonatal (n = 1), post-discharge (n = 1), infant (n = 1), and long-term mortality (n = 2). Higher parental education was associated with decreased odds/risk of neonatal (n = 1) and infant mortality (n = 5), but not with long-term mortality (n = 1). A meta-analysis of four US articles showed increased unadjusted odds of in-hospital mortality in those with government/public versus private health insurance (OR 1.40, 95% CI 1.24, 1.56). The association between area-based income and CHD-related mortality was conflicting, with three of eight articles reporting significant associations. CONCLUSION This systematic review provides evidence that children of lower SES are at increased risk of CHD-related mortality. As these children are over-represented in the CHD population, interventions targeting socio-economic inequalities could have a large impact on improving CHD survival.

Abstract
BACKGROUND Critically ill pediatric patients with endotracheal tubes routinely receive endotracheal tube suctioning to clear secretions and ensure tube patency. This common practice can result in adverse effects. OBJECTIVES The aim of this study was to evaluate the research literature on the stressors of endotracheal suctioning and consequent effect on the pediatric patient. METHODS An integrative review was conducted using the Whittemore and Knafl modified framework for integrative reviews, and article selection was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analyses flow diagram. A literature search was conducted via PubMed, the Cumulative Index to Nursing and Allied Health Literature, and Scopus. Selected articles were evaluated to present the current evidence on the stressors of endotracheal suctioning in the pediatric population. RESULTS This review includes 14 articles, with a total of 849 patients, ranging in age from premature neonates to 17 years of age. The available literature aligned into 3 categories: neurovascular effects, respiratory systems effects, and pain related to endotracheal tube suctioning. Pain was the most prevalent category, with half of the studies using endotracheal suctioning as a painful procedure to validate pain assessment tools rather than examining the effect of suctioning. A majority of the studies (67%) were conducted in the premature neonate population. Children with congenital cardiac or pulmonary defects, genetic syndromes, or neurological injuries were frequently excluded. CONCLUSIONS Literature regarding the effects of endotracheal suctioning in children is limited. There are many extrapersonal, interpersonal, and intrapersonal stressors associated with endotracheal suctioning that merit future research.

Abstract
Although collectively they are fairly common, birth defects receive limited attention as a group of outcomes either clinically or from a public health perspective. This article provides an overview of the prevalence, trends and selected socio-demographic risk factors for several major birth defects, including neural tube defects, cranio-facial anomalies, congenital heart defects, trisomies 13, 18, and 21, and gastroschisis and omphalocele. Attention should focus on strengthening existing registries, creating birth defects surveillance programs in states that do not have them, and standardizing registry methods so that broadly national data to monitor these trends are available.

Abstract
BACKGROUND A substantial proportion of infants born with tetralogy of Fallot (TOF) die in infancy. A better understanding of the heterogeneity associated with TOF, including extracardiac malformations and chromosomal anomalies is vital to stratifying risk and optimizing outcomes during infancy. METHODS Using the North Carolina Birth Defects Monitoring Program, infants diagnosed with TOF and born between 2003 and 2012 were included. Kaplan-Meier survival curves were used to estimate cumulative 1-year mortality, stratified by the presence of concomitant birth defects (BDs) and chromosomal anomalies. Multivariable logistic regression was used to estimate the direct effect of each concomitant BD, after adjusting for all others. RESULTS A total of 496 infants with TOF were included, and 15% (n = 76) died. The number of concomitant BD systems was significantly associated with the risk of death at 1-year, p < 0.0001. Specifically, the risk of mortality was 8% among infants with TOF with or without additional cardiac defects, 16% among infants with TOF and 1 extracardiac BD system, 19% among infants with 2 extracardiac BD systems, and 39% among infants with ≥ 3 extracardiac BD systems. After adjustment, concomitant eye and gastrointestinal defects were significantly associated increased with 1-year mortality, odds ratio 2.83 (95% confidence interval, 1.08-7.32) and odds ratio 4.43 (95% confidence interval, 1.57, 12.45), respectively. Infants with trisomy 13 or trisomy 18 were also significantly more likely to die, p < 0.0001. CONCLUSION Both concomitant BDs and genetic anomalies increase the risk of mortality among infants with TOF. Future studies are needed to identify the underlying genetic and socioeconomic risk factors for high-risk TOF infants. Birth Defects Research 109:1154-1165, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
OBJECTIVE Despite overall improvements in congenital heart disease outcomes, racial and ethnic disparities have continued. The purpose of this study is to examine the effect of race and ethnicity, as well as other risk factors on congenital heart surgery length of stay and in-hospital mortality. DESIGN From the 2012 Healthcare Cost and Utilization Project Kids Inpatient Database (KID), we identified 13 130 records with Risk Adjustment in Congenital Heart Surgery complexity score-eligible procedures. Multivariate logistic and linear regression modeling with survey weights, stratification and clustering was used to examine the relationships between predictor variables and length of stay as well as in-hospital mortality. RESULTS No significant mortality differences were found among all race and ethnicity groups across each age group. Black neonates and black infants had a longer length of stay (neonatal estimate = 8.73 days, P = .0034; infant estimate 1.10 days, P = .0253), relative to whites. Government-sponsored insurance was associated with increased odds of neonatal mortality (odds ratio = 1.51, P = .0055), increased length of stay in neonates (estimate = 4.26 days, P = .0009) and infants (estimate = 1.52 days, P = .0181), relative to private insurance. Government-sponsored insurance was associated with increased number of chronic conditions, which were also associated with increased LOS (estimate 8.39 days, P < .001 in neonates; estimate 3.60 days, P < .001 in infants; estimate 1.87 days, P < .001 children). CONCLUSIONS Racial/ethnic disparities in congenital heart surgical outcomes may be changing compared with previous studies using the KID database. Increased length of stay in children with government-sponsored insurance may reflect expansion of individual states government-sponsored insurance eligibility criteria for children with complex chronic medical conditions. These findings warrant cautious optimism regarding racial and ethnic disparities in congenital heart surgery outcomes.

Abstract
Congenital heart disease (CHD) is the most common birth defect, affecting about 0.8% of live births. Advances in recent decades have allowed >85% of children with CHD to survive to adulthood, creating a growing population of adults with CHD. Little information exists regarding survival, demographics, late outcomes, and comorbidities in this emerging group, and multiple barriers impede research in adult CHD. The National Heart, Lung, and Blood Institute and the Adult Congenital Heart Association convened a multidisciplinary working group to identify high-impact research questions in adult CHD. This report summarizes the meeting discussions in the broad areas of CHD-related heart failure, vascular disease, and multisystem complications. High-priority subtopics identified included heart failure in tetralogy of Fallot, mechanical circulatory support/transplantation, sudden cardiac death, vascular outcomes in coarctation of the aorta, late outcomes in single-ventricle disease, cognitive and psychiatric issues, and pregnancy.

Abstract
BACKGROUND Because of advancements in care, there has been a decline in mortality from congenital heart defects (CHDs) over the past several decades. However, there are no current empirical data documenting the number of people living with CHDs in the United States. Our aim was to estimate the CHD prevalence across all age groups in the United States in the year 2010. METHODS The age-, sex-, and severity-specific observed prevalence of CHDs in Québec, Canada, in the year 2010 was assumed to equal the CHD prevalence in the non-Hispanic white population in the United States in 2010. A race-ethnicity adjustment factor, reflecting differential survival between racial-ethnic groups through 5 years of age for individuals with a CHD and that in the general US population, was applied to the estimated non-Hispanic white rates to derive CHD prevalence estimates among US non-Hispanic blacks and Hispanics. Confidence intervals for the estimated CHD prevalence rates and case counts were derived from a combination of Taylor series approximations and Monte Carlo simulation. RESULTS We estimated that ≈2.4 million people (1.4 million adults, 1 million children) were living with CHDs in the United States in 2010. Nearly 300 000 of these individuals had severe CHDs. CONCLUSIONS Our estimates highlight the need for 2 important efforts: planning for health services delivery to meet the needs of the growing population of adults with CHD and the development of surveillance data across the life span to provide empirical estimates of the prevalence of CHD across all age groups in the United States.

Abstract
BackgroundWhile early outcomes of paediatric cardiac surgery have improved, less attention has been given to later outcomes including post-discharge mortality and emergency readmissions.ObjectivesOur objectives were to use a mixed-methods approach to build an evidenced-based guideline for postdischarge management of infants undergoing interventions for congenital heart disease (CHD).MethodsSystematic reviews of the literature – databases used: MEDLINE (1980 to 1 February 2013), EMBASE (1980 to 1 February 2013), Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1981 to 1 February 2013), The Cochrane Library (1999 to 1 February 2013), Web of Knowledge (1980 to 1 February 2013) and PsycINFO (1980 to 1 February 2013). Analysis of audit data from the National Congenital Heart Disease Audit and Paediatric Intensive Care Audit Network databases pertaining to records of infants undergoing interventions for CHD between 1 January 2005 and 31 December 2010. Qualitative analyses of online discussion posted by 73 parents, interviews with 10 helpline staff based at user groups, interviews with 20 families whose infant either died after discharge or was readmitted urgently to intensive care, and interviews with 25 professionals from tertiary care and 13 professionals from primary and secondary care. Iterative multidisciplinary review and discussion of evidence incorporating the views of parents on suggestions for improvement.ResultsDespite a wide search strategy, the studies identified for inclusion in reviews related only to patients with complex CHD, for whom adverse outcome was linked to non-white ethnicity, lower socioeconomic status, comorbidity, age, complexity and feeding difficulties. There was evidence to suggest that home monitoring programmes (HMPs) are beneficial. Of 7976 included infants, 333 (4.2%) died postoperatively, leaving 7634 infants, of whom 246 (3.2%) experienced outcome 1 (postdischarge death) and 514 (6.7%) experienced outcome 2 (postdischarge death plus emergency intensive care readmissions). Multiple logistic regression models for risk of outcomes 1 and 2 had areas under the receiver operator curve of 0.78 [95% confidence interval (CI) 0.75 to 0.82] and 0.78 (95% CI 0.75 to 0.80), respectively. Six patient groups were identified using classification and regression tree analysis to stratify by outcome 2 (range 3–24%), which were defined in terms of neurodevelopmental conditions, high-risk cardiac diagnosis (hypoplastic left heart, single ventricle or pulmonary atresia), congenital anomalies and length of stay (LOS) > 1 month. Deficiencies and national variability were noted for predischarge training and information, the process of discharge to non-specialist services including documentation, paediatric cardiology follow-up including HMP, psychosocial support post discharge and the processes for accessing help when an infant becomes unwell.ConclusionsNational standardisation may improve discharge documents, training and guidance on ‘what is normal’ and ‘signs and symptoms to look for’, including how to respond. Infants with high-risk cardiac diagnoses, neurodevelopmental conditions or LOS > 1 month may benefit from discharge via their local hospital. HMP is suggested for infants with hypoplastic left heart, single ventricle or pulmonary atresia. Discussion of postdischarge deaths for infant CHD should occur at a network-based multidisciplinary meeting. Audit is required of outcomes for this stage of the patient journey.Future workFurther research may determine the optimal protocol for HMPs, evaluate the use of traffic light tools for monitoring infants post discharge and develop the analytical steps and processes required for audit of postdischarge metrics.Study registrationThis study is registered as PROSPERO CRD42013003483 and CRD42013003484.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
OBJECTIVE To examine the survival of infants with hypoplastic left heart syndrome (HLHS) and potential influence of demographic and clinical characteristics on survival using population-based data. METHODS Infants with nonsyndromic HLHS (n = 212) born between 1979 and 2005 were identified through the Metropolitan Atlanta Congenital Defects Program. Vital status was ascertained through 2009 based on linkage with vital records. We estimated Kaplan-Meier survival probabilities stratified by select demographic and clinical characteristics. RESULTS The overall survival probability to 2009 was 24% and significantly improved over time: from 0% in 1979-1984 to 42% in 1999-2005. Survival probability was 66% during the first week, 27% during the first year of life, and 24% during the first 10 years. Survival of very low and low birth weight or preterm infants and those born in high-poverty neighborhoods was significantly poorer. For children with information on surgical intervention (n = 88), the overall survival was 52%, and preterm infants had significantly poorer survival (31%) compared with term infants (56%). For children who survived to 1 year of age, long-term survival was ∼90%. CONCLUSIONS Survival to adolescence of children with nonsyndromic HLHS born in metropolitan Atlanta has significantly improved in recent years, with those born full term, with normal birth weight, or in a low-poverty neighborhood having a higher survival probability. Survival beyond infancy to adolescence is high. A better understanding of the growing population of survivors with HLHS is needed to inform resource planning.

Racial/ethnic differences in survival of United States children with birth defects: a population-based study. J Pediatr 2015; 166:819-26.e1-2. [PMID: 25641238 PMCID: PMC4696483 DOI: 10.1016/j.jpeds.2014.12.025] [Citation(s) in RCA: 58] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2014] [Revised: 11/11/2014] [Accepted: 12/11/2014] [Indexed: 11/24/2022]
Abstract
OBJECTIVES To examine racial/ethnic-specific survival of children with major birth defects in the US. STUDY DESIGN We pooled data on live births delivered during 1999-2007 with any of 21 birth defects from 12 population-based birth defects surveillance programs. We used the Kaplan-Meier method to calculate cumulative survival probabilities and Cox proportional hazards models to estimate mortality risk. RESULTS For most birth defects, there were small-to-moderate differences in neonatal (<28 days) survival among racial/ethnic groups. However, compared with children born to non-Hispanic white mothers, postneonatal infant (28 days to <1 year) mortality risk was significantly greater among children born to non-Hispanic black mothers for 13 of 21 defects (hazard ratios [HRs] 1.3-2.8) and among children born to Hispanic mothers for 10 of 21 defects (HRs 1.3-1.7). Compared with children born to non-Hispanic white mothers, a significantly increased childhood (≤ 8 years) mortality risk was found among children born to Asian/Pacific Islander mothers for encephalocele (HR 2.6), tetralogy of Fallot, and atrioventricular septal defect (HRs 1.6-1.8) and among children born to American Indian/Alaska Native mothers for encephalocele (HR 2.8), whereas a significantly decreased childhood mortality risk was found among children born to Asian/Pacific Islander mothers for cleft lip with or without cleft palate (HR 0.6). CONCLUSION Children with birth defects born to non-Hispanic black and Hispanic mothers carry a greater risk of mortality well into childhood, especially children with congenital heart defect. Understanding survival differences among racial/ethnic groups provides important information for policy development and service planning.
