Delayed diagnosis and racial bias in children with genetic conditions

Area of Science:

• Medical Genetics
• Pediatric Health
• Health Disparities

Background:

• Increasing availability of genetic therapeutics necessitates prompt genetic diagnosis.
• Delayed diagnosis of genetic conditions contributes to significant health disparities in pediatric populations.
• Minority pediatric patients are disproportionately affected by diagnostic delays.

Purpose of the Study:

• To examine health system, provider, and patient-level factors contributing to delayed genetic diagnosis in minority pediatric patients.
• To identify root causes of health disparities in genetic care access.
• To propose actionable strategies for improving equitable access to genetic diagnosis and care.

Main Methods:

• Analysis of clinical cases involving pediatric patients from minority populations.
• Examination of contributing factors at multiple levels: health system, provider, and patient.
• Literature review on genetic diagnosis and health equity.

Main Results:

• Identified key factors across health system, provider, and patient domains that impede timely genetic diagnosis.
• Demonstrated a link between diagnostic delays and racial health disparities in pediatric genetic conditions.
• Highlighted the urgent need for systemic interventions to ensure equitable care.

Conclusions:

• Addressing systemic, provider, and patient-level barriers is essential for timely and equitable genetic diagnosis.
• Interventions aimed at improving genetic care access for minority children can reduce health disparities.
• Ensuring equitable access to genetic diagnosis is critical for the effective utilization of emerging genetic therapeutics.
