Racial, ethnic, and socio-economic disparities in neonatal ICU admissions among neonates born with cyanotic CHD in the United States, 2009-2018.

INTRODUCTION: Disparities in CHD outcomes exist across the lifespan. However, less is known about disparities for patients with CHD admitted to neonatal ICU. We sought to identify sociodemographic disparities in neonatal ICU admissions among neonates born with cyanotic CHD. MATERIALS & METHODS: Annual natality files from the US National Center for Health Statistics for years 2009-2018 were obtained. For each neonate, we identified sex, birthweight, pre-term birth, presence of cyanotic CHD, and neonatal ICU admission at time of birth, as well as maternal age, race, ethnicity, comorbidities/risk factors, trimester at start of prenatal care, educational attainment, and two measures of socio-economic status (Special Supplemental Nutrition Program for Women, Infants, and Children [WIC] status and insurance type). Multivariable logistic regression models were fit to determine the association of maternal socio-economic status with neonatal ICU admission. A covariate for race/ethnicity was then added to each model to determine if race/ethnicity attenuate the relationship between socio-economic status and neonatal ICU admission. RESULTS: Of 22,373 neonates born with cyanotic CHD, 77.2% had a neonatal ICU admission. Receipt of WIC benefits was associated with higher odds of neonatal ICU admission (adjusted odds ratio [aOR] 1.20, 95% CI 1.1-1.29, p < 0.01). Neonates born to non-Hispanic Black mothers had increased odds of neonatal ICU admission (aOR 1.20, 95% CI 1.07-1.35, p < 0.01), whereas neonates born to Hispanic mothers were at lower odds of neonatal ICU admission (aOR 0.84, 95% CI 0.76-0.93, p < 0.01). CONCLUSION: Maternal Black race and low socio-economic status are associated with increased risk of neonatal ICU admission for neonates born with cyanotic CHD. Further work is needed to identify the underlying causes of these disparities.

Neighborhood Social Vulnerability and Interstage Weight Gain: Evaluating the Role of a Home Monitoring Program.

Background Poor interstage weight gain is a risk factor for adverse outcomes in infants with hypoplastic left heart syndrome. We sought to examine the association of neighborhood social vulnerability and interstage weight gain and determine if this association is modified by enrollment in our institution's Infant Single Ventricle Management and Monitoring Program (ISVMP). Methods and Results We performed a retrospective single-center study of infants with hypoplastic left heart syndrome before (2007-2010) and after (2011-2020) introduction of the ISVMP. The primary outcome was interstage weight gain, and the secondary outcome was interstage growth failure. Multivariable linear and logistic regression models were used to examine the association between the Social Vulnerability Index and the outcomes. We introduced an interaction term into the models to test for effect modification by the ISVMP. We evaluated 217 ISVMP infants and 111 pre-ISVMP historical controls. The Social Vulnerability Index was associated with interstage growth failure (P=0.001); however, enrollment in the ISVMP strongly attenuated this association (P=0.04). Pre-ISVMP, as well as high- and middle-vulnerability infants gained 4 g/d less and were significantly more likely to experience growth failure than low-vulnerability infants (high versus low: adjusted odds ratio [aOR], 12.5 [95% CI, 2.5-62.2]; middle versus low: aOR, 7.8 [95% CI, 2.0-31.2]). After the introduction of the ISVMP, outcomes did not differ by Social Vulnerability Index tertile. Infants with middle and high Social Vulnerability Index scores who were enrolled in the ISVMP gained 4 g/d and 2 g/d more, respectively, than pre-ISVMP controls. Conclusions In infants with hypoplastic left heart syndrome, high social vulnerability is a risk factor for poor interstage weight gain. However, enrollment in the ISVMP significantly reduces growth disparities.

Feasibility of Digital Stethoscopes in Telecardiology Visits for Interstage Monitoring in Infants with Palliated Congenital Heart Disease.

Infants with staged surgical palliation for congenital heart disease are at high-risk for interstage morbidity and mortality. Interstage telecardiology visits (TCV) have been effective in identifying clinical concerns and preventing unnecessary emergency department visits in this high-risk population. We aimed to assess the feasibility of implementing auscultation with digital stethoscopes (DSs) during TCV and the potential impact on interstage care in our Infant Single Ventricle Monitoring & Management Program. In addition to standard home-monitoring practice for TCV, caregivers received training on use of a DS (Eko CORE attachment assembled with Classic II Infant Littman stethoscope). Sound quality of the DS and comparability to in-person auscultation were evaluated based on two providers' subjective assessment. We also evaluated provider and caregiver acceptability of the DS. From 7/2021 to 6/2022, the DS was used during 52 TCVs in 16 patients (median TCVs/patient: 3; range: 1-8), including 7 with hypoplastic left heart syndrome. Quality of heart sounds and murmur auscultation were subjectively equivalent to in-person findings with excellent inter-rater agreement (98%). All providers and caregivers reported ease of use and confidence in evaluation with the DS. In 12% (6/52) of TCVs, the DS provided additional significant information compared to a routine TCV; this expedited life-saving care in two patients. There were no missed events or deaths. Use of a DS during TCV was feasible in this fragile cohort and effective in identifying clinical concerns with no missed events. Longer term use of this technology will further establish its role in telecardiology.

Association of Home Monitoring and Unanticipated Interstage Readmissions in Infants With Hypoplastic Left Heart Syndrome.

Background The impact of home monitoring on unanticipated interstage readmissions in infants with hypoplastic left heart syndrome has not been previously studied. We sought to examine the association of our institution's Infant Single Ventricle Management and Monitoring Program (ISVMP) with readmission frequency, cumulative readmission days, and readmission illness severity and to identify patient-level risk factors for readmission. Methods and Results We performed a retrospective single-center cohort study comparing infants with hypoplastic left heart syndrome enrolled in ISVMP (December 2010-December 2019) to historical controls (January 2007-November 2010). The primary outcome was number of readmissions per interstage days. Secondary outcomes were cumulative interstage readmission days and occurrence of severe readmissions. Inverse probability weighted and multivariable generalized linear models were used to examine the association between ISVMP and the outcomes. We compared 198 infants in the ISVMP to 128 historical controls. Infants in the ISVMP had more than double the risk of interstage readmission compared with controls (adjusted incidence rate ratio, 2.38 [95% CI, 1.50-3.78]; P=0.0003). There was no difference in cumulative interstage readmission days (adjusted incidence rate ratio, 1.02 [95% CI, 0.69-1.50]; P=0.90); however, infants in the ISVMP were less likely to have severe readmissions (adjusted odds ratio, 0.28 [95% CI, 0.11-0.68]; P=0.005). Other factors independently associated with number of readmissions included residing closer to our center, younger gestational age, genetic syndrome, and discharge on exclusive enteral feeds. Conclusions Infants in the ISVMP had more frequent readmissions but comparable readmission days and fewer severe unanticipated readmissions. These findings suggest that home monitoring can reduce interstage morbidity without increasing readmission days.

Relationship Between Serum Brain-Type Natriuretic Peptide and Biomarkers of Growth in Infants With Shunt-Dependent Single Cardiac Ventricle.

For infants with shunt-dependent or ductal-dependent single ventricle heart disease, poor growth is common and associated with morbidity and impaired neurodevelopmental outcomes. Although attention has focused on nutrition to promote weight gain, little is known about the relation between heart failure and growth factors. A prospective observational pilot study was performed to assess the relation between heart failure, assessed by brain natriuretic peptide (BNP), and growth factors (insulin-like growth factor 1 [IGF-1] and insulin-like growth factor-binding protein 3) at 3 visits: (1) before discharge from neonatal intervention with the establishment of stable pulmonary blood flow, (2) immediately before superior cavopulmonary connection, and (3) before discharge after superior cavopulmonary connection operation. The relation between BNP and growth factors was analyzed using Spearman pairwise correlations at each visit and modeled over time with a linear mixed-effects model. Correlations were considered worthy of further exploration using a p <0.10, given the exploratory nature of the study. The study included 38 infants (66% male, 68% hypoplastic left heart syndrome). Median BNP was elevated at visit 1 and decreased over time (287 pg/dl [interquartile range 147 to 794], 85 pg/dl [52 to 183], and 90 pg/dl [70 to 138]). Median IGF-1 Z score was <0 at each visit but increased over time (-0.9 [interquartile range -1.1 to 0.1], -0.7 [-1.2 to 0.1], and -0.5 [-1.2 to 0]). Inverse correlations were found between BNP and IGF-1 at visit 1 (r = -0.40, p = 0.097), BNP and IGF-1 and insulin-like growth factor-binding protein 3 at visit 2 (r = -0.33, p = 0.080 and r = -0.33, p = 0.085, respectively) and BNP and IGF-1 Z score at visit 3 (r = -0.42, p = 0.049). Significant relations were likewise found between the change in BNP and the change in IGF-1 between visits 1 and 3 (p = 0.046) and between visits 2 and 3 (p = 0.048). In conclusion, this pilot study demonstrates an inverse correlation between BNP and growth factors, suggesting that the heart failure state associated with this physiology may play a mechanistic role in impaired growth.

Reflexiones sobre una rotación educativa en simulación médica / Reflections on an educational rotation in medical simulation

Mientras que la enseñanza y el aprendizaje son la clave para avanzar en medicina, se dedica poco tiempo a cómo enseñar. Tradicionalmente, los estudiantes de medicina rotan a través de las especialidades médicas estándares con el objetivo de aprender a diagnosticar y tratar las enfermedades más comunes. Muy pocas facultades de medicina ofrecen una rotación o un currículo formal sobre educación médica. Se reflexiona sobre la experiencia de unos estudiantes de medicina al realizar una rotación educativa electiva en el Hospital virtual Valdecilla, un centro de simulación clínica en España con la misión de mejorar la seguridad del paciente mediante el entrenamiento de los profesionales sanitarios y estudiantes de pregrado a través de la simulación clínica en todas sus aplicaciones. La rotación de los estudiantes se realizó a través del Programa Internacional de Salud de la Facultad de Medicina de la Universidad de Nueva York. Se repasan los objetivos de aprendizaje abordados (creación de entornos de aprendizaje psicológicamente seguros, diseño de las estrategias docentes basadas en la teoría de aprendizaje del adulto de Kolb, exposición a los diferentes tipos de simulaciones, introducción al debriefing y al trabajo en equipo, y participación en un proyecto de investigación educativa) y se compara la experiencia con su participación en las simulaciones como estudiantes durante la facultad

While teaching and learning are key elements to advance medicine, little time is spent educating medical professionals on how to teach. Traditionally, medical students rotate through the standard medical specialties with the goal of learning how to diagnose and treat the most common diseases. Few medical schools offer a teaching rotation or formal curriculum in education. We reflect on the experience of medical students in a one-month educational elective at the Hospital virtual Valdecilla in Santander (Spain), a simulation center with the mission of improving quality of care and patient safety by means of interprofessional team training through clinical simulation. The medical student rotation was made possible by the International Health Program at New York University School of Medicine. Learning objectives for the rotation are reviewed, including development of psychologically safe learning environments, design of learning activities based on principles of the adult experiential learning model described by Kolb, exposure to different types of simulation, introduction to debriefing and teamwork principles, and participation in an educational research project. The students’ experience in this rotation is compared to their previous experience participating in simulations as students during clinical rotations at their medical school

Parent health literacy and "obesogenic" feeding and physical activity-related infant care behaviors.

OBJECTIVE: To examine the relationship between parent health literacy and "obesogenic" infant care behaviors. STUDY DESIGN: Cross-sectional analysis of baseline data from a cluster randomized controlled trial of a primary care-based early childhood obesity prevention program (Greenlight). English- and Spanish-speaking parents of 2-month-old children were enrolled (n = 844). The primary predictor variable was parent health literacy (Short Test of Functional Health Literacy in Adults; adequate ≥ 23; low <23). Primary outcome variables involving self-reported obesogenic behaviors were: (1) feeding content (more formula than breast milk, sweet drinks, early solid food introduction), and feeding style-related behaviors (pressuring to finish, laissez-faire bottle propping/television [TV] watching while feeding, nonresponsiveness in letting child decide amount to eat); and (2) physical activity (tummy time, TV). Multivariate logistic regression analyses (binary, proportional odds models) performed adjusting for child sex, out-of-home care, Women, Infants, and Children program status, parent age, race/ethnicity, language, number of adults/children in home, income, and site. RESULTS: Eleven percent of parents were categorized as having low health literacy. Low health literacy significantly increased the odds of a parent reporting that they feed more formula than breast milk, (aOR = 2.0 [95% CI: 1.2-3.5]), immediately feed when their child cries (aOR = 1.8 [1.1-2.8]), bottle prop (aOR = 1.8 [1.002-3.1]), any infant TV watching (aOR = 1.8 [1.1-3.0]), and inadequate tummy time (<30 min/d), (aOR = 3.0 [1.5-5.8]). CONCLUSIONS: Low parent health literacy is associated with certain obesogenic infant care behaviors. These behaviors may be modifiable targets for low health literacy-focused interventions to help reduce childhood obesity.

Prevalence of obesity among patients with congenital and acquired heart disease.

Overweight and obesity rates have risen dramatically in the United States, with subsequent detrimental comorbidity risks. The rates for obesity among children with congenital and acquired heart disease have rarely been reported. A retrospective cross-sectional study was conducted to determine the prevalence of overweight and obesity in children with heart disease and to identify subgroups at increased risk. A total of 795 cases were identified from a chart review of patients presenting to an urban center's Pediatric Cardiology Program between 1 January and 31 December 2006. A body mass index (BMI) at the 85th percentile or higher was defined as overweight, and a BMI at the 95th percentile or higher was defined as obese. Subjects with comorbidities affecting body habitus were excluded from the study. Overall, overweight and obesity rates were similar to national data. No significant differences in overweight or obesity rates were detected between heart disease and non-heart disease groups (P = 0.50). According to multivariate analysis, Hispanic ethnicity and male gender were the only predictors of obesity. This study shows that children with heart disease are not immune to the common predictors of obesity such as gender and ethnicity and that the future care of children with heart disease should include general discussions about the risks for obesity.
