Disruptions in the development of feeding for infants with congenital heart disease

Feeding Variation Among Infants in Acute Care Cardiology Units

Infants with heart disease are at high risk of feeding difficulties and complications. Feeding practices amongst acute care cardiology units are not standardized. This study aims to describe feeding practices for infants at the time of discharge from a Pediatric Acute Care Cardiology Collaborative (PAC3) center and practice variation between centers. Discharge encounters for infants in the PAC3 registry between February 2019 and October 2021 were included. Nutrition type and feeding route at discharge were summarized with descriptive statistics and a modified bump plot. Center variation was assessed using funnel plots with control limits set at the 99.9% confidence interval from the group mean. A total of 15,414 encounters across 24 PAC3 centers were recorded from 8313 unique patients (median encounters 1, range 1-25). Nutrition at discharge consisted of standard formula in 8368 (54%), human milk in 6300 (41%), and elemental formula in 3230 (21%), either alone or in combination. Feeds were fortified to ≥ 24 kcal/oz in 12,359 (80%). Discharge supplemental tube feeding was present in 7353 (48%) encounters with 4643 (63%) receiving continuous feeds, 2144 (29%) bolus feeds, and 566 (8%) a combination. Funnel plots demonstrated variability in nutrition type and feeding route at discharge. Infants with heart disease commonly require high calorie nutrition and supplemental tube feedings at discharge. Feeding strategies at discharge vary widely between PAC3 centers. Collaborative approaches to identify best practices in feeding strategies are needed.

Experiences in Tube Weaning Children with Congenital Heart Disease and Oral Feeding Aversion

Infants and children with congenital heart disease (CHD) often require supplemental nutrition via tube feeding before and after surgery. Tube feeding may be required due to poor weight gain, inadequate oral-motor skills, and/or reduced endurance for oral feeding. Our team has described a successful approach to weaning this population (Horsley et al. (2022) Pediatr Cardiol 43:1429-1437). A subgroup of tube-fed patients with CHD who demonstrate oral feeding aversion (OA) presents unique challenges to the tube weaning process. We discuss our team's experience with tube weaning orally averse children with CHD. Of 36 patients enrolled in the Cincinnati Children's Heart Institute Cardiology Feeding Tube Wean Clinic, 11 (31%) were determined to have oral feeding aversion (OA) by a speech-language pathologist (SLP). Descriptive data comparing the OA group to the non-averse group was gathered prior to and during the wean. Both groups had the ability to tube wean successfully, although the OA group had lower median oral intake (9 vs 24%) and higher age at start of the wean (9 vs 4 months). Those with OA also had a longer median duration of wean in days (17 vs 12 days) and higher likelihood of return to tube feeds within six-month post-wean (22 vs 0%). Additionally, the OA group had a higher percentage of genetic syndromes (36 vs 16%), although this was not found to be statistically significant in this study. Children with OA present with unique challenges for tube weaning. The results of this study show that weaning children with CHD and OA is possible with a multidisciplinary team who is knowledgeable about this population.

The Effect of Physiotherapy Intervention on an Infant With Congenital Heart Defect Associated With Developmental Delay: A Case Report

Congenital heart defects (CHDs) are one of the most prevalent anomalies present at birth globally. Children with CHD often face developmental challenges, including motor, language, and cognitive impairments. This case report presents the clinical profile of a 1.2-year-old female child with CHD and developmental delay (DD) post-CHD surgery. The child exhibited delayed gross motor, fine motor, language, and personal-social milestones, along with significant cardiac anomalies observed on CT angiograms. Physiotherapy interventions were initiated to address these DDs, encompassing manual techniques, neurodevelopmental treatment, and multimodal stimulation. The objective of this study was to assess the impact of physiotherapy interventions on improving developmental outcomes in infants with CHD-associated DD. The New Ballard Score and Hammersmith Infant Neurological Examination were utilized to evaluate improvements post-intervention. Significant enhancements in developmental outcomes were observed. This case underscores the significance of holistic care approaches in mitigating the impact of CHD on developmental trajectories and improving the quality of life for affected children.

Prevalence and Risk Factors for Tube-Feeding at Discharge in Infants following Early Congenital Heart Disease Surgery: A Single-Center Cohort Study

OBJECTIVE

 Oral feeding difficulty is common in infants after congenital heart disease (CHD) surgical repair and is associated with prolonged hospital stay and increased risk for tube-feeding at discharge (TF). The current understanding of the enteropathogenesis of oral feeding difficulty in infants requiring CHD surgery is limited. To determine the prevalence and risk factors for TF following CHD surgery in early infancy.

STUDY DESIGN

 This was a 6-year single-center retrospective cohort study (2016-2021) of infants under 6 months who had CHD surgery. Infants required TF were compared with infants who reached independent oral feeding (IOF).

RESULTS

 Of the final sample of 128 infants, 24 (18.8%) infants required TF at discharge. The risk factors for TF in univariate analysis include low birth weight, low 5-minute Apgar score, admitted at birth, risk adjustment in congenital heart surgery categories IV to VI, presence of genetic diagnosis, use of Prostin, higher pre- and postsurgery respiratory support, lower weight at surgery, lower presurgery oral feeding, higher presurgery milk calory, delayed postsurgery enteral and oral feeding, higher pre- and postsurgery gastroesophageal reflux disease (GERD), need for swallow study, abnormal brain magnetic resonance imaging (p < 0.05). In the multivariate analysis, only admitted at birth, higher presurgery milk calories, and GERD were significant risk factors for TF. TF had significantly longer hospital stay (72 vs. 17 days) and lower weight gain at discharge (z-score: -3.59 vs. -1.94) compared with IOF (p < 0.05).

CONCLUSION

 The prevalence of TF at discharge in our study is comparable to previous studies. Infants with CHD admitted at birth, received higher presurgery milk calories, and clinical GERD are significant risk factors for TF. Mitigating the effects of identified risk factors for TF will have significant impact on the quality of life for these infants and their families and may reduce health care cost.

KEY POINTS

· Oral feeding difficulty in infants after congenital heart disease surgical repair is common.. · Such infants require prolonged hospital stay and higher risk for tube-feeding at discharge.. · Identifying modifiable risk factors associated with tube-feeding can enhance clinical outcomes..

Neurodevelopmental Outcomes for Individuals With Congenital Heart Disease: Updates in Neuroprotection, Risk-Stratification, Evaluation, and Management: A Scientific Statement From the American Heart Association

Over the past decade, new research has advanced scientific knowledge of neurodevelopmental trajectories, factors that increase neurodevelopmental risk, and neuroprotective strategies for individuals with congenital heart disease. In addition, best practices for evaluation and management of developmental delays and disorders in this high-risk patient population have been formulated based on literature review and expert consensus. This American Heart Association scientific statement serves as an update to the 2012 statement on the evaluation and management of neurodevelopmental outcomes in children with congenital heart disease. It includes revised risk categories for developmental delay or disorder and an updated list of factors that increase neurodevelopmental risk in individuals with congenital heart disease according to current evidence, including genetic predisposition, fetal and perinatal factors, surgical and perioperative factors, socioeconomic disadvantage, and parental psychological distress. It also includes an updated algorithm for referral, evaluation, and management of individuals at high risk. Risk stratification of individuals with congenital heart disease with the updated categories and risk factors will identify a large and growing population of survivors at high risk for developmental delay or disorder and associated impacts across the life span. Critical next steps must include efforts to prevent and mitigate developmental delays and disorders. The goal of this scientific statement is to inform health care professionals caring for patients with congenital heart disease and other key stakeholders about the current state of knowledge of neurodevelopmental outcomes for individuals with congenital heart disease and best practices for neuroprotection, risk stratification, evaluation, and management.

Undernutrition in young children with congenital heart disease undergoing cardiac surgery in a low-income environment

BACKGROUND

Malnutrition (undernutrition) in children with congenital disease (CHD) is a notable concern, with preoperative and persistent growth failure post-cardiac surgery contributing to poorer outcomes. Poor growth in children with CHD in low-income environments is exacerbated by feeding difficulties, poverty, delayed diagnosis, and late corrective surgery. This study describes and compares the growth of young children with CHD undergoing cardiac surgery in central South Africa from before to 6-months after cardiac surgery.

METHODS

Children 30 months and younger, with their mothers, were included in this prospective observational descriptive study. Weight- height-, and head circumference-for-age z-scores were used to identify children who were underweight, stunted and microcephalic. Z-scores for growth indices were compared from baseline to 3-months and 6-months post-cardiac surgery. Changes in growth over time were calculated using a 95% confidence interval on the difference between means. Linear regression was used to determine the association between growth and development, health-related quality of life and parenting stress respectively.

RESULTS

Forty mother-child pairs were included at baseline. Most children (n = 30) had moderate disease severity, with eight children having cyanotic defects. A quarter of the children had Down syndrome (DS). Twenty-eight children underwent corrective cardiac surgery at a median age of 7.4 months. Most children (n = 27) were underweight before cardiac surgery [mean z-score - 2.5 (±1.5)], and many (n = 18) were stunted [mean z-score - 2.2 (±2.5)]. A quarter (n = 10) of the children had feeding difficulties. By 6-months post-cardiac surgery there were significant improvements in weight (p = 0.04) and head circumference (p = 0.02), but complete catch-up growth had not yet occurred. Malnutrition (undernutrition) was strongly associated (p = 0.04) with poorer motor development [Mean Bayley-III motor score 79.5 (±17.5)] before cardiac surgery. Growth in children with cyanotic and acyanotic defects, and those with and without DS were comparable.

CONCLUSION

Malnutrition (undernutrition) is common in children with CHD in central South Africa, a low-income environment, both before and after cardiac surgery, and is associated with poor motor development before cardiac surgery. A diagnosis of CHD warrants regular growth monitoring and assessment of feeding ability. Early referral for nutritional support and speech therapy will improve growth outcomes.

Feeding Characteristics in Children With Food Allergies: A Scoping Review

BACKGROUND

Food allergy (FA) affects approximately 8% of children and may be immunoglobulin E (IgE)-mediated or non-IgE-mediated. It is recognized clinically that children with both subtypes of FA may present with features of pediatric feeding disorder (PFD); however, there is currently a limited detail of presenting characteristics.

OBJECTIVE

The objective of this study was to synthesize the current evidence regarding the feeding characteristics of children with FA, with a focus on the feeding skills and psychosocial domains of PFD.

METHOD

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Papers published between 2001 and 2022 describing feeding characteristics in the feeding skills and psychosocial domains in children with FA/history of FA were included. Papers that focused solely on characteristics from the medical or nutritional domains were excluded. Descriptive information regarding demographics, methodology, allergy profile and history, and the characteristics of PFD observed was extracted using a preconceived data extraction form.

RESULTS

Overall, 40 papers contained descriptions of feeding characteristics of children with non-IgE-mediated FA (n = 22) and IgE-mediated FA (n = 11), while four were nonspecific. In the psychosocial domain, food refusal/aversion, anxiety with eating, and poor intake were the most frequently reported, regardless of FA subtype. Less information was reported regarding feeding skills, although slowness in eating, immature diet, and delays in oral sensory-motor skills were described.

CONCLUSIONS

Children with FA/history of FA may present with a range of characteristics that map across the feeding skill and psychosocial domains of PFD. Systematic research is needed to fully describe the feeding characteristics of children with FA.

Developmental care pathway for hospitalised infants with CHD: on behalf of the Cardiac Newborn Neuroprotective Network, a Special Interest Group of the Cardiac Neurodevelopmental Outcome Collaborative

Infants and children born with CHD are at significant risk for neurodevelopmental delays and abnormalities. Individualised developmental care is widely recognised as best practice to support early neurodevelopment for medically fragile infants born premature or requiring surgical intervention after birth. However, wide variability in clinical practice is consistently demonstrated in units caring for infants with CHD. The Cardiac Newborn Neuroprotective Network, a Special Interest Group of the Cardiac Neurodevelopmental Outcome Collaborative, formed a working group of experts to create an evidence-based developmental care pathway to guide clinical practice in hospital settings caring for infants with CHD. The clinical pathway, "Developmental Care Pathway for Hospitalized Infants with Congenital Heart Disease," includes recommendations for standardised developmental assessment, parent mental health screening, and the implementation of a daily developmental care bundle, which incorporates individualised assessments and interventions tailored to meet the needs of this unique infant population and their families. Hospitals caring for infants with CHD are encouraged to adopt this developmental care pathway and track metrics and outcomes using a quality improvement framework.

Feeding at 6-12 months in infants with CHD

BACKGROUND

Feeding difficulty is common in infants with CHD.

OBJECTIVE

The purpose of this study was to describe the feeding skills and behaviours of infants with CHD at 6-12 months of age and explore relationships between feeding, gastrointestinal distress, and gastroesophageal reflux.

METHODS

Parents of 30 infants with CHD completed online surveys when their infant was 6, 8, 10, and 12 months old. Surveys included parent-report measures of feeding skills (Child Oral and Motor Proficiency Scale), feeding behaviours (Pediatric Eating Assessment Tool), symptoms of gastrointestinal distress (Infant Gastrointestinal Symptoms Questionnaire), and gastroesophageal reflux (Infant Gastroesophageal Reflux Questionnaire-Revised).

RESULTS

We found that 95, 32, 67, and 30% of infants were delayed in their feeding skill development at 6, 8, 10, and 12 months, respectively. Symptoms of problematic feeding behaviours were similarly high, with 90, 62, 29, and 38% of infants meeting criteria for problematic feeding at 6, 8, 10, and 12 months, respectively. Feeding skills and behaviours were related but unique contributors. Feeding behaviours were related to both gastrointestinal distress and gastroesophageal reflux, but feeding skills were rarely related to either.

CONCLUSIONS

Delayed acquisition of feeding skills and problematic feeding were common in infants with CHD. Infants with more gastrointestinal and gastroesophageal reflux symptoms had more symptoms of problematic feeding behaviours.

CLINICAL IMPLICATIONS

Comprehensive assessment, targeted interventions, and early involvement of feeding specialists are important to support feeding in infants with CHD through at least the first year of life.

Optimising motor development in the hospitalised infant with CHD: factors contributing to early motor challenges and recommendations for assessment and intervention

BACKGROUND

Neurodevelopmental challenges are the most prevalent comorbidity associated with a diagnosis of critical CHD, and there is a high incidence of gross and fine motor delays noted in early infancy. The frequency of motor delays in hospitalised infants with critical CHD requires close monitoring from developmental therapies (physical therapists, occupational therapists, and speech-language pathologists) to optimise motor development. Currently, minimal literature defines developmental therapists' role in caring for infants with critical CHD in intensive or acute care hospital units.

PURPOSE

This article describes typical infant motor skill development, how the hospital environment and events surrounding early cardiac surgical interventions impact those skills, and how developmental therapists support motor skill acquisition in infants with critical CHD. Recommendations for healthcare professionals and those who provide medical or developmental support in promotion of optimal motor skill development in hospitalised infants with critical CHD are discussed.

CONCLUSIONS

Infants with critical CHD requiring neonatal surgical intervention experience interrupted motor skill interactions and developmental trajectories. As part of the interdisciplinary team working in intensive and acute care settings, developmental therapists assess, guide motor intervention, promote optimal motor skill acquisition, and support the infant's overall development.

Wayfinding through the "ocean of the great unknown": how lactating parents establish a direct breastfeeding relationship with an infant with critical CHD

INTRODUCTION

Lactating parents of infants hospitalised for critical congenital heart disease (CHD) face significant barriers to direct breastfeeding. While experiences of directly breastfeeding other hospitalised neonates have been described, studies including infants with critical CHD are scarce. There is no evidence-based standard of direct breastfeeding care for these infants, and substantial practice variation exists.

AIM

To explain how direct breastfeeding is established with an infant hospitalised for critical CHD, from lactating parents' perspectives.

MATERIALS & METHODS

This study is a qualitative grounded dimensional analysis of interviews with 30 lactating parents of infants with critical CHD who directly breastfed within 3 years. Infants received care from 26 United States cardiac centres; 57% had single ventricle physiology. Analysis included open, axial, and selective coding; memoing; member checking; and explanatory matrices.

RESULTS

Findings were represented by a conceptual model, "Wayfinding through the 'ocean of the great unknown'." The core process of Wayfinding involved a nonlinear trajectory requiring immense persistence in navigating obstacles, occurring in a context of life-and-death consequences for the infant. Wayfinding was characterised by three subprocesses: navigating the relationship with the healthcare team; protecting the direct breastfeeding relationship; and doing the long, hard work. Primary influencing conditions included relentless concern about weight gain, the infant's clinical course, and the parent's previous direct breastfeeding experience.

CONCLUSIONS

For parents, engaging in the Wayfinding process to establish direct breastfeeding was feasible and meaningful - though challenging. The conceptual model of Wayfinding explains how direct breastfeeding can be established and provides a framework for research and practice.

Quantifying the Healthcare Burden of Pediatric Feeding Disorder after Congenital Heart Surgery

OBJECTIVE

To determine the healthcare costs and use burden of pediatric feeding disorder after congenital heart surgery.

STUDY DESIGN

A retrospective, population-based cohort study using claims data (2009-2018) was performed. Participants include patients aged 0-18 years who had undergone congenital heart surgery and were included in the insurance database ≥1 year after surgery. The main exposure variable was the presence of a pediatric feeding disorder, defined as a need for a feeding tube at discharge or diagnosis of dysphagia or feeding-related difficulty within the study timeframe. Main outcomes include overall and feeding-related medical care use, defined as readmissions and outpatient use, and feeding-related cost of care within 1 year of surgery.

RESULTS

A total of 10 849 pediatric patients were identified, with 3347 (30.9%) presenting with pediatric feeding disorder within 1 year of surgery. Patients with pediatric feeding disorder spent a median of 12 days (IQR, 6-33 days) in the hospital, compared with 5 days (IQR, 3-8 days) in patients without (P < .001). Rate ratios for overall readmissions, feeding-related readmissions, feeding-related outpatient use, and cost of care over the first year after surgery were significantly increased at 2.9 (95% CI, 2.5-3.4), 5.1 (95% CI, 4.6-5.7), 7.7 (95% CI, 6.5-9.1), and 2.2 (95% CI, 2.0-2.3) among patients with pediatric feeding disorder as compared with those without.

CONCLUSIONS

Pediatric feeding disorder after congenital heart surgery is associated with a significant healthcare burden. Multidisciplinary care for and research on this health condition is needed to identify optimal management strategies to reduce this burden and improve outcomes.

Predictors of Human Milk Feeding and Direct Breastfeeding for Infants with Single Ventricle Congenital Heart Disease: Machine Learning Analysis of the National Pediatric Cardiology Quality Improvement Collaborative Registry

OBJECTIVE

To identify factors that support or limit human milk (HM) feeding and direct breastfeeding (BF) for infants with single ventricle congenital heart disease at neonatal stage 1 palliation (S1P) discharge and at stage 2 palliation (S2P) (∼4-6 months old).

STUDY DESIGN

Analysis of the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) registry (2016-2021; 67 sites). Primary outcomes were any HM, exclusive HM, and any direct BF at S1P discharge and at S2P. The main analysis involved multiple phases of elastic net logistic regression on imputed data to identify important predictors.

RESULTS

For 1944 infants, the strongest predictor domain areas included preoperative feeding, demographics/social determinants of health, feeding route, clinical course, and site. Significant findings included: preoperative BF was associated with any HM at S1P discharge (OR = 2.02, 95% CI = 1.74-3.44) and any BF at S2P (OR = 2.29, 95% CI = 1.38-3.80); private/self-insurance was associated with any HM at S1P discharge (OR = 1.91, 95% CI = 1.58-2.47); and Black/African-American infants had lower odds of any HM at S1P discharge (OR = 0.54, 95% CI = 0.38-0.65) and at S2P (0.57, 0.30-0.86). Adjusted odds of HM/BF practices varied among NPC-QIC sites.

CONCLUSIONS

Preoperative feeding practices predict later HM and BF for infants with single ventricle congenital heart disease; therefore, family-centered interventions focused on HM/BF during the S1P preoperative time are needed. These interventions should include evidence-based strategies to address implicit bias and seek to minimize disparities related to social determinants of health. Future research is needed to identify supportive practices common to high-performing NPC-QIC sites.

Human Milk Feeding and Direct Breastfeeding Improve Outcomes for Infants With Single Ventricle Congenital Heart Disease: Propensity Score-Matched Analysis of the NPC-QIC Registry

Background Infants with single ventricle congenital heart disease undergo 3 staged surgeries/interventions, with risk for morbidity and mortality. We estimated the effect of human milk (HM) and direct breastfeeding on outcomes including necrotizing enterocolitis, infection-related complications, length of stay, and mortality. Methods and Results We analyzed the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) registry (2016-2021), examining HM/breastfeeding groups during stage 1 and stage 2 palliations. We calculated propensity scores for feeding exposures, then fitted Poisson and logistic regression models to compare outcomes between propensity-matched cohorts. Participants included 2491 infants (68 sites). Estimates for all outcomes were better in HM/breastfeeding groups. Infants fed exclusive HM before stage 1 palliation (S1P) had lower odds of preoperative necrotizing enterocolitis (odds ratio [OR], 0.37 [95% CI, 0.17-0.84]; P=0.017) and shorter S1P length of stay (rate ratio [RR], 0.87 [95% CI, 0.78-0.98]; P=0.027). During the S1P hospitalization, infants with high HM had lower odds of postoperative necrotizing enterocolitis (OR, 0.28 [95% CI, 0.15-0.50]; P<0.001) and sepsis (OR, 0.29 [95% CI, 0.13-0.65]; P=0.003), and shorter S1P length of stay (RR, 0.75 [95% CI, 0.66-0.86]; P<0.001). At stage 2 palliation, infants with any HM (RR, 0.82 [95% CI, 0.69-0.97]; P=0.018) and any breastfeeding (RR, 0.71 [95% CI, 0.57-0.89]; P=0.003) experienced shorter length of stay. Conclusions Infants with single ventricle congenital heart disease in high-HM and breastfeeding groups experienced multiple significantly better outcomes. Given our findings of improved health, strategies to increase the rates of HM/breastfeeding in these patients should be implemented. Future research should replicate these findings with granular feeding data and in broader congenital heart disease populations, and should examine mechanisms (eg, HM components, microbiome) by which HM/breastfeeding benefits these infants.

Safety and Feasibility of Skin-to-Skin Contact in the Delivery Room for High-Risk Cardiac Neonates

Early skin-to-skin contact (SSC), beginning in the delivery room, provides myriad health benefits for mother and baby. Early SSC in the delivery room is the standard of care for healthy neonates following both vaginal and cesarean delivery. However, there is little published evidence on the safety of this practice in infants with congenital anomalies requiring immediate postnatal evaluation, including critical congenital heart disease (CCHD). Currently, the standard practice following delivery of infants with CCHD in many delivery centers has been immediate separation of mother and baby for neonatal stabilization and transfer to a different hospital unit or a different hospital altogether. However, most neonates with prenatally diagnosed congenital heart disease, even those with ductal-dependent lesions, are clinically stable in the immediate newborn period. Therefore, we sought to increase the percentage of newborns with prenatally diagnosed CCHD who are born in our regional level II-III delivery hospitals who receive mother-baby SSC in the delivery room. Using quality improvement methodology, through a series of Plan-Do-Study-Act cycles we successfully increased mother-baby skin-to-skin contact in the delivery room for eligible cardiac patients born across our city-wide delivery hospitals from a baseline 15% to greater than 50%.

Human milk feeding and direct breastfeeding improve outcomes for infants with single ventricle congenital heart disease: Propensity score matched analysis of the NPC-QIC registry

Background

Infants with single ventricle (SV) congenital heart disease (CHD) undergo three staged surgeries/interventions, with risk for morbidity and mortality. We estimated the effect of human milk (HM) and direct breastfeeding (BF) on outcomes including necrotizing enterocolitis (NEC), infection-related complications, length of stay (LOS), and mortality.

Methods

We analyzed the National Pediatric Cardiology Quality Improvement Collaborative registry (2016-2021), examining HM/BF groups during stage 1 (S1P) and stage 2 (S2P) palliations. We calculated propensity scores for feeding exposures, then fitted Poisson and logistic regression models to compare outcomes between propensity-matched cohorts.

Results

Participants included 2491 infants (68 sites). Estimates for all outcomes were better in HM/BF groups. Infants fed exclusive HM before S1P had lower odds of preoperative NEC (OR=0.37, 95% CI=0.17-0.84, p=0.017) and shorter S1P LOS (RR=0.87, 0.78-0.98, p=0.027). During the S1P hospitalization, infants with high HM had lower odds of postoperative NEC (OR=0.28, 0.15-0.50, p<0.001) and sepsis (0.29, 0.13-0.65, p=0.003), and shorter S1P LOS (RR=0.75, 0.66-0.86, p<0.001). At S2P, infants with any HM (0.82, 0.69-0.97, p=0.018) and any BF (0.71, 0.57-0.89, p=0.003) experienced shorter LOS.

Conclusions

Infants with SV CHD in high HM and BF groups experienced multiple significantly better outcomes. Given our findings of improved health, strategies to increase the rates of HM/BF in these patients should be implemented. Future research should replicate these findings with granular feeding data and in broader CHD populations, and should examine mechanisms (eg, HM components; microbiome) by which HM/BF benefits these infants.

Clinical Perspective

What is new?: This is the first large, multisite study examining the impact of human milk and breastfeeding on outcomes for infants with single ventricle congenital heart disease.All outcome estimates were better in high human milk and breastfeeding groups, with significantly lower odds of necrotizing enterocolitis, sepsis, and infection-related complications; and significantly shorter length of stay at both the neonatal stage 1 palliation and the subsequent stage 2 palliation.All estimates of all-cause mortality were substantially lower in human milk and breastfeeding groups, with clinically important estimates of 75%-100% lower odds of mortality in direct breastfeeding groups.What are the clinical implications?: There is a critical need for improved, condition-specific lactation support to address the low prevalence of human milk and breastfeeding for infants with single ventricle congenital heart disease.Increasing the dose and duration of human milk and direct breastfeeding has strong potential to substantially improve the health outcomes of these vulnerable infants.

Determinants of Length of Stay after Neonatal Cardiac Surgery Using Path Analysis

After neonatal cardiac surgery, families, and the health care team strive for exclusive oral feedings before hospital discharge. With the hypothesis that exclusive oral feedings would reduce the length of stay (LOS), a multidimensional path analysis was used to examine a cross-section of 280 neonates from 2009 to 2013. Buttigieg, Abela, and Pace's theoretical framework of structural and process-related determinants of LOS was modeled with hypothesis-driven correlation and directionality. The recursive path model had a good global and local fit with outcome variances of 26% for exclusive oral feeding and LOS. In the full cohort and model groups (single and biventricular), when controlling for covariances: sepsis, birth distance, necrotizing enterocolitis, genetic differences, specialty consults, the age at which neonatal cardiac surgery occurred (β = .23, p ≤ .001) and the duration of postoperative intubation (β = .47, p ≤ .001) more significantly influenced the LOS than intermediate mediation of exclusive oral feedings at discharge.

Developmental Care for Hospitalized Infants With Complex Congenital Heart Disease: A Science Advisory From the American Heart Association

Developmental disorders, disabilities, and delays are a common outcome for individuals with complex congenital heart disease, yet targeting early factors influencing these conditions after birth and during the neonatal hospitalization for cardiac surgery remains a critical need. The purpose of this science advisory is to (1) describe the burden of developmental disorders, disabilities, and delays for infants with complex congenital heart disease, (2) define the potential health and neurodevelopmental benefits of developmental care for infants with complex congenital heart disease, and (3) identify critical gaps in research aimed at evaluating developmental care interventions to improve neurodevelopmental outcomes in complex congenital heart disease. This call to action targets research scientists, clinicians, policymakers, government agencies, advocacy groups, and health care organization leadership to support funding and hospital-based infrastructure for developmental care in the complex congenital heart disease population. Prioritization of research on and implementation of developmental care interventions in this population should be a major focus in the next decade.

Tutorial on Clinical Practice for Use of the Fiberoptic Endoscopic Evaluation of Swallowing Procedure With Pediatric Populations: Part 2

PURPOSE

This is Part 2 of a two-part tutorial series establishing clinical guidelines pertaining to the administration of fiberoptic endoscopic evaluation of swallowing (FEES) developed by representatives of the American Board of Swallowing and Swallowing Disorders, all of whom are members of Special Interest Group 13. Whereas Part 1 focused on use of FEES with adults and included general information common to using FEES in any population, the purpose of this tutorial is to provide clinicians with updated best practice clinical guidelines for performing, interpreting, and documenting outcomes when using FEES with the pediatric population. This document has two main sections. The first section discusses the history of pediatric FEES, needed knowledge and skill pertaining to all elements of performing and interpreting the examination including detailed information related to indications and contraindications, developmental anatomical and physiological changes across childhood, preparing for and conducting the examination, medical collaboration, and patient safety. The second section provides detailed guidelines for clinicians who require training for use of FEES with the pediatric population.

CONCLUSIONS

This first of its kind tutorial offers guidelines for clinicians who perform, interpret, and/or want to train to perform FEES in the pediatric population. Important clinical distinctions exist when using FEES with the pediatric population versus with the adult population. Developmental changes, pediatric medical frailty, provider-parent/caregiver interaction, collaboration with physician colleagues, and patient safety are representative of key areas highlighted in this document.

Clinical Phenotypes of Malnutrition in Young Children: Differential Nutritional Correction

This review article summarizes current data on malnutrition etiology and pathogenesis in infants. Topical requirements for revealing this condition, its diagnosis and severity assessment via centile metrics are presented. The characteristics of the most common clinical phenotypes of postnatal growth insufficiency in infants (premature infants with different degree of maturation, including patients with bronchopulmonary dysplasia) are described. Differential approaches for malnutrition nutritional correction in these children are presented. The final section of the article describes special nutritional needs for children with congenital heart defects in terms of hemodynamic disorders nature and severity. Modern nutritional strategies for preparation of these patients to surgery and for their postoperative period are presented. The use of high-calorie/high-protein product for malnutrition correction in the most vulnerable patients with described in this review phenotypes is worth noticing.

Assessment and management of feeding difficulties for infants with complex CHD

Early surgical intervention in infants with complex CHD results in significant disruptions to their respiratory, gastrointestinal, and nervous systems, which are all instrumental to the development of safe and efficient oral feeding skills. Standardised assessments or treatment protocols are not currently available for this unique population, requiring the clinician to rely on knowledge based on neonatal literature. Clinicians need to be skilled at evaluating and analysing these systems to develop an appropriate treatment plan to improve oral feeding skill and safety, while considering post-operative recovery in the infant with complex CHD. Supporting the family to re-establish their parental role during the hospitalisation and upon discharge is critical to reducing parental stress and oral feeding success.

Habilitation of Executive Functions in Pediatric Congenital Heart Disease Patients through LEGO®-Based Therapy: A Quasi-Experimental Study

Congenital heart disease is defined as an abnormality in the cardiocirculatory structure or function. Various studies have shown that patients with this condition may present cognitive deficits. To compensate for this, several therapeutic strategies have been developed, among them, the LEGO® Education sets, which use the pedagogic enginery to modify cognitive function by didactic material based on mechanics and robotics principles. Accordingly, the goal of this study was to evaluate the effect of cognitive habilitation by using LEGO®-based therapy in pediatric congenital heart disease patients. This was a quasi-experimental study; eligible patients were identified, and their general data were obtained. In the treatment group, an initial evaluation with the neuropsychological BANFE-2 test was applied; then, once a week, the interventions were performed, with a final test at the end of the interventions. In the control group, after the initial evaluation, a second appointment was scheduled for the final evaluation. Our results show that >50% of children presented cognitive impairment; nevertheless, there was an overall improvement in treatment patients, showing a significant increase in BANFE scores in areas related to executive functions. LEGO®-based therapy may be useful to improve cognitive abilities; however, future research should be performed to strengthen the data.

Assessing the Association Between Pre-operative Feeding and the Development of Oral Feeding Skills in Infants with Single Ventricle Heart Disease: An Analysis of the NPC-QIC Dataset

Pre-operative feeding may improve long-term feeding outcomes in single ventricle patients, including weaning from supplemental tube feedings in infancy. This study examines the association between pre-operative enteral feeding and subsequent long-term feeding outcomes while also assessing the counterbalancing risk of necrotizing enterocolitis (NEC). Secondary analysis of the National Pediatric Cardiology Quality Improvement Collaborative database was performed. The association between pre-operative feeding practice and achieving all oral feeds through the first year of life was examined using a multivariable regression model. Similarly, the association between pre-operative oral feeding and NEC was also assessed. Of 944 patients with 1-year feeding outcomes available, 58% were fed preoperatively (41.3% exclusively oral) and 12.3% were not fed per institutional approach. At hospital discharge after Stage 1 palliation, 57% required a feeding tube, while 39% required a feeding tube at their first birthday. In infants who were orally fed, the odds ratio to achieving tube-free feeding at 1 year was not significantly increased (1.3, confidence interval 0.8-2.0). Of 1740 infants with pre-operative feeding and Stage 1 there was no statistically significant difference in NEC among patients who were preoperatively fed versus those that were not fed per institutional approach (p = 0.2). Pre-operative feeding of infants with single ventricle heart disease was not associated with early achievement of tube-free feeding in the first year of life. However, pre-operative oral feeding was also not associated with increased risk of NEC, suggesting that it can be safely offered among appropriate patients.

Neurological features in infants with congenital heart disease

AIM

To report neurological examination findings at 5 to 12 months of age in infants with congenital heart disease (CHD) and to identify predictors of abnormal neurological examination.

METHOD

This retrospective observational study included infants who required cardiac surgery at less than 3 months of age and underwent a standard neurological examination from a neurologist in the cardiac neurodevelopmental outpatient clinic between age 5 months and 12 months. Predictors for abnormal neurological examination (concerns on structured developmental history, demographic factors, medical history, and newborn neurodevelopmental assessment) were considered for multivariate regression.

RESULTS

The sample included 127 infants (mean age 7mo 2wks), who underwent first cardiac surgery at 7 days (4-49 interquartile range [IQR]) of age and were seen for a neurological examination in the cardiac neurodevelopmental clinic. Neurological abnormalities were common; 88% of infants had an abnormal neurological examination in at least one domain assessed. The most common abnormalities were abnormal axial (48%) and extremity (44%) tone, mostly hypotonia. Abnormal neurological examination was associated with concerns on the concurrent structured developmental history, genetic condition, extracardiac anomaly, longer length of stay, more than one cardiac surgery, ongoing early intervention services, and abnormalities on newborn neurodevelopmental assessment.

INTERPRETATION

Neurological examination abnormalities are common in infants with CHD after infant heart surgery, supporting the need for early and ongoing therapeutic developmental services and adherence to American Heart Association recommendations for developmental follow-up for children with CHD. What this paper adds Neurological examination abnormalities are common in infants who undergo open-heart surgery. Medical complications in infancy increase risk for neurological abnormalities. Family-reported concerns on structured developmental history may predict abnormal neurological examination at 5 to 12 months of age. Abnormal newborn neurodevelopmental assessment may predict abnormal neurological examination at 5 to 12 months of age.

Impact of perinatal management on neurodevelopmental outcomes in congenital heart disease

With advancements in cardiopulmonary bypass technique and perioperative care, there has been a progressive decline in mortality associated with neonatal surgical correction of congenital heart disease (CHD). Thus, there is now increased focus on improving neurodevelopmental outcomes in CHD survivors. While the cause of these neurodevelopmental impairments is multifactorial, there is increasing evidence that structural and functional cerebral abnormalities are present before cardiac corrective repair. This suggests that in addition to patient specific risk factors, underlying cardiac physiology and clinical hemodynamics are critical to brain health and development. Prenatal diagnosis of CHD and subsequent optimization of perinatal care may therefore be important modifiable factors for long-term neurodevelopmental outcome. This article reviews the impact that prenatal diagnosis of CHD has on perinatal care and the preoperative clinical status of a neonate, as well as the potential influence this may have on lessening the degree of cerebral injury and long-term neurodevelopmental impairments.

Feeding outcomes in post-discharge feeding clinic for infants following cardiac surgery

INTRODUCTION

The aim of this study was to describe the development and assess the usefulness of a feeding clinic to help infants with CHD tolerate the highest level of oral feeding while achieving growth velocity and supporting neurodevelopment.

MATERIALS AND METHODS

This retrospective, cohort study assessed feeding outcomes for infants who underwent cardiac surgery at <30 days of age with cardiopulmonary bypass between February 2016 and April 2020. Diagnoses, age at surgery, hospitalisation variables, and feeding outcomes were compared between two cohorts, pre- and post-implementation of a specialised feeding clinic using Exact Wilcoxon signed-rank test, chi-squared, or Fisher's exact test. The association between time to full oral feed and risk factors was assessed using univariable and multivariable Cox regression model.

RESULTS

Post-clinic infants (n = 116) surgery was performed at a median of 6 days of life (interquartile range: 4, 8) with median hospital length of stay of 19 days (interquartile range: 16, 26). Infants' median age at first clinic visit was at 30 days old (interquartile range: 24, 40) and took median 10 days (interquartile range: 7, 12) after hospital discharge to first clinic visit. In the post-clinic cohort, the median time to 100% oral feeding was 47 days (interquartile range: 27, 96) compared to the 60 days (interquartile range: 20, 84) in the pre-clinic cohort (n = 22), but the difference was not statistically significant.

DISCUSSION

The cardiac feeding clinic was utilised by our neonatal surgery population and feasible in coordination with cardiology follow-up visits. Future assessment of cardiac feeding clinic impact should include additional measures of feeding and neurodevelopmental success.

Current Strategies to Optimize Nutrition and Growth in Newborns and Infants with Congenital Heart Disease: A Narrative Review

(1) Objective: This review aims to identify the clinical and practical barriers to optimizing nutrition in newborn infants with congenital heart disease (CHD) and to describe updated evidence-based recommendations for clinical and nutritional management of these patients in a narrative review. (2) Research Methods and Procedures: We conducted a search of the relevant literature published from 2000 to December 2021. (3) Results: CHD patients undergo several nutritional challenges related to the underlying cardiac disease anomaly, the potential increased risk of NEC, and delayed enteral feeding, resulting in inadequate energy intake and sub-optimal growth, increased morbidity and mortality. (4) Conclusions: To optimize nutrition and growth in newborn infants with CHD, standardized protocols should be implemented. Regular nutritional and growth assessment with a multi-disciplinary team is essential. We propose a decisional algorithm that may represent a potentially useful tool to guide clinicians to optimize growth and nutrition.

Oral Aversion in Infants With Congenital Heart Disease: A Single-Center Retrospective Cohort Study

OBJECTIVES

Neonates undergoing cardiac surgery are at risk for oral aversion (OA). OA is not well described outside of the index hospitalization and impacts patients and families. We evaluated the prevalence of OA at 1 year old after neonatal cardiopulmonary bypass (CPB) surgery.

DESIGN

Retrospective cohort study.

SETTING

Single quaternary care hospital.

SUBJECTS

Our cohort included 157 neonates who underwent CPB surgery from 2014 to 2017 and had follow-up data available at 1 year old.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Three feeding experts reviewed the medical record to define children with OA; 30% of charts were evaluated in triplicate for validation. Neonates with and without OA were compared in univariate analysis, and risk factors for OA were explored in a limited multivariable analysis. OA was present at 1 year in 37 patients (23.6%) and other feeding difficulties were present in an additional 29 patients (18.5%). Thirty-eight patients (24.2%) had a feeding tube, including 12 (7.6%) with a gastrostomy tube. Factors associated with OA at 1 year included total ICU days, duration of mechanical ventilation, total number of nil per os days, and number of postoperative days (PODs) until oral feeding initiation (all p < 0.0001). Number of POD until oral feeding initiation remained independently associated with OA at 1 year in multivariable analysis (adjusted odds ratio, 1.08; 95% CI, 1.04-1.12; p < 0.0001). Infants with any oral intake at discharge had lower odds of OA at 1 year (0.21; 95% CI, 0.08-0.5; p = 0.0003). At hospital discharge, 132 patients (84.1%) were taking some oral feeds, and 128 patients (81.5%) received tube feeding.

CONCLUSIONS

OA and other feeding difficulties are common at 1 year old in neonates undergoing CPB surgery. Delayed exposure to oral intake may be a modifiable risk factor for OA and efforts to improve early oral feeding could lead to better functional outcomes.

Evaluating dysphagia in infants with congenital heart disease using Fiberoptic Endoscopic Evaluation of Swallowing

OBJECTIVE

Dysphagia is common in infants with congenital heart disease (CHD). However, there is minimal published data regarding its management outside of the perioperative period. The objective of this study is to describe the role of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in the diagnosis and management of dysphagia in infants with CHD.

METHODS

Infants with CHD who underwent FEES exam for evaluation of swallowing dysfunction between February 2015 and February 2021 at a university-based, tertiary care urban pediatric hospital were studied. Demographic data, presenting symptoms, medical history, and dysphagia history were examined. The validated Dysphagia Outcome and Severity Scale (DOSS) was used to standardize and compare dysphagia severity.

RESULTS

62 FEES exams were performed on 48 patients. All 48 patients were diagnosed with dysphagia and had a mean dysphagia severity score (DOSS) of 2.68. Patients with wet laryngeal congestion on presentation had worse mean DOSS score and were more likely to demonstrate aspiration on FEES exam (p < 0.01). There was no significant difference in mean DOSS or presence of aspiration when comparing infants who had cardiothoracic surgery, vocal cord paralysis, or lower respiratory tract illness with those who had not (p > 0.05).

CONCLUSION

A FEES exam is an effective and well-tolerated procedure for evaluating swallowing dysfunction in pediatric patients with CHD and its use reduces radiation exposure for this vulnerable population. Wet laryngeal congestion was found to be predictive of more severe dysphagia and aspiration. There is no significant association between severity of dysphagia or aspiration on FEES exam and history of cardiac surgery, vocal cord paralysis, or lower respiratory tract illness.

Feeding Problems and Long-Term Outcomes in Preterm Infants—A Systematic Approach to Evaluation and Management

Preterm infants are known to have long-term healthcare needs. With advances in neonatal medical care, younger and more preterm infants are surviving, placing a subset of the general population at risk of long-term healthcare needs. Oral feeding problems in this population often play a substantial yet under-appreciated role. Oral feeding competency in preterm infants is deemed an essential requirement for hospital discharge. Despite achieving discharge readiness, feeding problems persist into childhood and can have a residual impact into adulthood. The early diagnosis and management of feeding problems are essential requisites to mitigate any potential long-term challenges in preterm-born adults. This review provides an overview of the physiology of swallowing and oral feeding skills, disruptions to oral feeding in preterm infants, the outcomes of preterm infants with feeding problems, and an algorithmic approach to the evaluation and management of neonatal feeding problems.

Rehabilitation in Pediatric Heart Failure and Heart Transplant

Survival of pediatric patients with heart failure has improved due to medical and surgical advances over the past decades. The complexity of pediatric heart transplant patients has increased as medical and surgical management for patients with congenital heart disease continues to improve. Quality of life in patients with heart failure and transplant might be affected by the impact on functional status that heart failure, heart failure complications or treatment might have. Functional areas affected might be motor, exercise capacity, feeding, speech and/or cognition. The goal of rehabilitation is to enhance and restore functional ability and quality of life to those with physical impairments or disabilities. Some of these rehabilitation interventions such as exercise training have been extensively evaluated in adults with heart failure. Literature in the pediatric population is limited yet promising. The use of additional rehabilitation interventions geared toward specific complications experienced by patients with heart failure or heart transplant are potentially helpful. The use of individualized multidisciplinary rehabilitation program that includes medical management, rehabilitation equipment and the use of physical, occupational, speech and feeding therapies can help improve the quality of life of patients with heart failure and transplant.
