Clinical Report: Evaluating Autism Screening in Pediatric Patients with CHD

Overview

This commentary discusses autism screening and diagnosis in children with congenital heart defects (CHD), highlighting that 14.6% screened positive and 11.7% received a diagnosis, significantly higher than the general population estimate of 2%. The study emphasizes the need for careful interpretation of these findings due to limitations in the dataset, including a small sample size and potential biases.

Background

Congenital heart disease (CHD) is the most common structural birth anomaly. As perioperative mortality decreases, attention has shifted to the neurodevelopmental outcomes of these patients. Autism spectrum disorder (ASD) screening in this population is critical, given the potential for higher rates of neurodevelopmental disorders compared to the general population. Understanding the relationship between CHD and autism is essential for improving long-term outcomes in affected children, as indicated by recent studies.

Data Highlights

14.6% of children screened positive for autism, while 11.7% received a diagnosis. Only 48 out of 94 eligible children completed screening, with only 7 positive results. The sensitivity estimate for the screening was 66%–67%, with a wide confidence interval.

Key Findings

• 14.6% of children screened positive for autism, while 11.7% received a diagnosis.
• These rates are more than threefold higher than the general population estimate of 2% for autism, as reported in the literature.
• Only 48 out of 94 eligible children completed screening, with only 7 positive results.
• The sensitivity estimate for the screening was 66%–67%, with a wide confidence interval.
• High specificity and negative predictive value were observed compared to other high-risk cohorts.
• Children with CHD may exhibit traits that mimic autism without meeting full diagnostic criteria.

Clinical Implications

Clinicians should be aware of the limitations in screening and diagnosis of autism in children with CHD, particularly regarding the small sample size and potential biases in the study. Comprehensive evaluations by qualified professionals remain essential for accurate diagnosis, as emphasized in the literature.

Conclusion

The findings highlight the need for careful interpretation of autism screening results in children with CHD, emphasizing the importance of structured follow-up and comprehensive assessments as supported by the study.
