Structured Tube Weaning Using the Hunger Provocation Method in Infants with Single Ventricle Heart Defects: A Multicenter Study.

Despite improvement in hemodynamics, children with single ventricle heart disease remain on feeding tubes long after stage 2 palliation (S2P). Use of a hunger provocation method in a multidisciplinary team setting has been successful at weaning these children from feeding tubes. The objective of this study is to describe patient characteristics and outcomes in the single ventricle population who underwent a formal tube weaning process using a standardized hunger provocation method. Single ventricle patients after S2P from six centers were included. Patient data collected included baseline demographics, swallow evaluation results, and feeding characteristics such as percent oral intake at the start of tube wean. Tube wean data included tube weaning process and duration, interruptions to the tube wean, adverse events, and weights before, during, and after the tube wean. 94% (60 of 64) of patients achieved oral independence. The median time to tube wean was 12.5 days. 62% of patients had transient weight loss during the tube wean. 61% of the cohort was taking less than 10% goal volumes by mouth with 90% of those patients successfully tube weaned. All patients with history of aspiration were successfully tube weaned. 75% of successfully weaned patients were above baseline weight at 1-month post-tube wean. The most common cause of tube wean interruption was contraction of a viral illness. Use of a standardized tube weaning process via hunger provocation method is both feasible and safe in the single ventricle population, resulting in successful feeding tube removal in a timely manner with minimal adverse effects.

Predictors of psychosocial adaptation in children with CHD.

Survival of CHD has significantly improved, but children with CHD remain susceptible to neurodevelopmental and psychosocial impairments. Our goal was to investigate the association between socio-demographic factors and psychosocial adaptation for future intervention. A retrospective cross-sectional study of an independent children's hospital's records was conducted. Psychosocial adaptation was measured by the Pediatric Cardiac Quality of Life Inventory Psychosocial Impact score (range 0-50, higher score indicates greater psychosocial adaptation). Bivariate and regression analyses were performed to estimate relationships between Psychosocial Impact score and socio-demographic variables including Child Opportunity Index, family support, financial support, academic support, and extracurricular activities. A total of 159 patients were included. Compared to patients in high opportunity neighbourhoods, patients in low opportunity neighbourhoods had a 9.27 (95% confidence interval [-17.15, -1.40], p = 0.021) point lower Psychosocial Impact score, whereas patients in moderate opportunity neighbourhoods had a 15.30 (95% confidence interval [-25.38, -5.22], p = 0.003) point lower Psychosocial Impact score. Compared to patients with adequate family support, those with limited support had a 6.23 point (95% confidence interval [-11.82, -0.643], p = 0.029) lower Psychosocial Impact score. Patients in moderate opportunity neighbourhoods had a higher Psychosocial Impact score by 11.80 (95% confidence interval [1.68, 21.91], p = 0.022) when they also had adequate family support compared to those with limited family support. Our findings indicate that among children with CHD, psychosocial adaptation is significantly impacted by neighbourhood resources and family support structures. These findings identify possible modifiable and protective factors to improve psychosocial adaptation in this vulnerable population.

Clinical Outcomes After Tracheostomy in Children With Single Ventricle Physiology: Collaborative Research From the Pediatric Cardiac Intensive Care Society Multicenter Cohort, 2010-2021.

OBJECTIVES: Multicenter studies reporting outcomes following tracheostomy in children with congenital heart disease are limited, particularly in patients with single ventricle physiology. We aimed to describe clinical characteristics and outcomes in a multicenter cohort of patients with single ventricle physiology who underwent tracheostomy before Fontan operation. DESIGN: Multicenter retrospective cohort study. SETTING: Twenty-one tertiary care pediatric institutions participating in the Collaborative Research from the Pediatric Cardiac Intensive Care Society. PATIENTS: We reviewed 99 children with single ventricle physiology who underwent tracheostomy before the Fontan operation at 21 institutions participating in Collaborative Research from the Pediatric Cardiac Intensive Care Society between January 2010 and December 2020, with follow-up through December 31, 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Death occurred in 51 of 99 patients (52%). Cox proportional hazard analysis was performed to determine factors associated with death after tracheostomy. Results are presented as hazard ratio (HR) with 95% CIs. Nonrespiratory indication(s) for tracheostomy (HR, 2.21; 95% CI, 1.14-4.32) and number of weeks receiving mechanical ventilation before tracheostomy (HR, 1.06; 95% CI, 1.02-1.11) were independently associated with greater hazard of death. In contrast, diagnosis of tricuspid atresia or Ebstein's anomaly was associated with less hazard of death (HR, 0.16; 95% CI, 0.04-0.69). Favorable outcome, defined as survival to Fontan operation or decannulation while awaiting Fontan operation with viable cardiopulmonary physiology, occurred in 29 of 99 patients (29%). Median duration of mechanical ventilation before tracheostomy was shorter in patients who survived to favorable outcome (6.1 vs. 12.1 wk; p < 0.001), and only one of 16 patients with neurologic indications for tracheostomy and 0 of ten patients with cardiac indications for tracheostomy survived to favorable outcome. CONCLUSIONS: For children with single ventricle physiology who undergo tracheostomy, mortality risk is high and should be carefully considered when discussing tracheostomy as an option for these children. Favorable outcomes are possible, although thoughtful attention to patient selection and tracheostomy timing are likely necessary to achieve this goal.

Health Equity and Policy Considerations for Pediatric and Adult Congenital Heart Disease Care among Minoritized Populations in the United States.

Achieving health equity in populations with congenital heart disease (CHD) requires recognizing existing disparities throughout the lifespan that negatively and disproportionately impact specific groups of individuals. These disparities occur at individual, institutional, or system levels and often result in increased morbidity and mortality for marginalized or racially minoritized populations (population subgroups (e.g., ethnic, racial, social, religious) with differential power compared to those deemed to hold the majority power in the population). Creating actionable strategies and solutions to address these health disparities in patients with CHD requires critically examining multilevel factors and health policies that continue to drive health inequities, including varying social determinants of health (SDOH), systemic inequities, and structural racism. In this comprehensive review article, we focus on health equity solutions and health policy considerations for minoritized and marginalized populations with CHD throughout their lifespan in the United States. We review unique challenges that these populations may face and strategies for mitigating disparities in lifelong CHD care. We assess ways to deliver culturally competent CHD care and to help lower-health-literacy populations navigate CHD care. Finally, we review system-level health policies that impact reimbursement and research funding, as well as institutional policies that impact leadership diversity and representation in the workforce.
