Literacy is a major social determinant of health, rooted in skills that develop during early childhood. Children arriving at kindergarten unprepared to learn to read are more likely to have low reading proficiency thereafter. General and health literacy are highly correlated, affecting understanding of health conditions, treatment adherence, and transition to self-care and adult healthcare services. The American Academy of Pediatrics (AAP) recommends literacy and school readiness promotion during well-visits and neurodevelopmental surveillance is emphasized across primary and subspecialty care. While genetic and environmental risk factors for reading difficulties are well-established, risks related to complex and chronic medical conditions are less appreciated and under-researched. This review applies an eco-bio-developmental framework to explore literacy across five complex chronic conditions affecting millions of children worldwide: asthma, cancer, congenital heart disease, epilepsy, and sickle cell disease. In each, integration of an efficient reading brain network may be impacted by direct factors, such as ischemia, anesthesia, and/or medications, and also indirect factors, such as altered parent–child routines, hospital stays, and missed school. By integrating literacy into care management plans for affected children, pediatric primary care and specialty providers are poised to identify risks early, target guidance and interventions, and improve academic and health outcomes. Impact While genetic and environmental risk factors for reading difficulties are well-established, risks related to complex and/or chronic medical conditions such as asthma, cancer, congenital heart disease, epilepsy, and sickle cell disease are substantial, less appreciated, and under-researched. General and health literacy are highly correlated, with implications for the understanding one’s health condition, treatment adherence, and transitioning to self-care, which is especially important for children with complex and/or chronic illness. Pediatric primary care and specialty providers are poised to integrate reading and literacy into care management plans for children with complex and/or chronic illness, including early screening, guidance, support, and interventions.

Background: CHD is the most common birth defect type, with one-fourth of patients requiring intervention in the first year of life. Caregiver understanding of CHD may vary. Health literacy may be one factor contributing to this variability. Methods: The study occurred at a large, free-standing children’s hospital. Recruitment occurred at a free-of-charge CHD camp and during outpatient cardiology follow-up visits. The study team revised the CHD Guided Questions Tool from an eighth- to a sixth-grade reading level. Caregivers of children with CHD completed the “Newest Vital Sign” health literacy screen and demographic surveys. Health literacy was categorised as “high” (Newest Vital Sign score 4–6) or “low” (score 0–3). Caregivers were randomised to read either the original or revised Guided Questions Tool and completed a validated survey measuring understandability and actionability of the Guided Questions Tool. Understandability and actionability data analysis used two-sample t-testing, and within demographic group differences in these parameters were assessed via one-way analysis of variance. Results: Eighty-two caregivers participated who were largely well educated with a high income. The majority (79.3%) of participants scored “high” for health literacy. No differences in understanding (p = 0.43) or actionability (p = 0.11) of the original and revised Guided Questions Tool were noted. There were no socio-economic-based differences in understandability or actionability (p > 0.05). There was a trend towards improved understanding of the revised tool (p = 0.06). Conclusions: This study demonstrated that readability of the Guided Questions Tool could be improved. Future work is needed to expand the study population and further understand health literacy’s impact on the CHD community.

Introduction: Patients with cyanotic heart disease are at an increased risk of developing thrombosis. Aspirin has been the mainstay of prophylactic anticoagulation for shunt-dependent patients with several reports of prevalent aspirin resistance, especially in neonates. We investigate the incidence of aspirin resistance and its relationship to thrombotic events and mortality in a cohort of infants with shunt-dependent physiology. Methods: Aspirin resistance was assessed using the VerifyNow™ test on infants with single-ventricle physiology following shunt-dependent palliation operations. In-hospital thrombotic events and mortality data were collected. Statistical analysis was performed to evaluate the effect of aspirin resistance on in-hospital thrombotic events and mortality risk. Results: Forty-nine patients were included with 41 of these patients being neonates. Six patients (12%) were aspirin resistant. A birth weight < 2500 grams was a significant factor associated with aspirin resistance (p = 0.04). Following a dose increase or additional dose administration, all patients with initial aspirin resistance had a normal aspirin response. There was no statistically significant difference between aspirin resistance and non-resistance groups with respect to thrombotic events. However, a statistically significant incidence of in-hospital mortality in the presence of thrombotic events was observed amongst aspirin-resistant patients (p = 0.04) in this study. Conclusion: Low birth weight was associated with a higher incidence of aspirin resistance. Inadequate initial dosing appears to be the primary reason for aspirin resistance. The presence of both thrombotic events and aspirin resistance was associated with significantly higher in-hospital mortality indicating that these patients warrant closer monitoring.
