Pediatric echocardiograms performed at primary centers: Diagnostic errors and missing links!

Area of Science:

• Pediatric Cardiology
• Diagnostic Imaging
• Medical Quality Assurance

Background:

• Pediatric echocardiography is crucial for diagnosing congenital heart disease (CHD).
• Accuracy of echocardiograms performed at non-tertiary centers is not well-established.
• Variations in performer expertise may influence diagnostic quality.

Purpose of the Study:

• To assess the accuracy of pediatric echocardiograms performed at non-tertiary centers.
• To identify factors associated with inaccurate echocardiogram interpretations.
• To evaluate the impact of discrepancies on patient management.

Main Methods:

• Retrospective review of 182 pediatric echocardiogram reports from non-tertiary centers.
• Comparison with echocardiograms performed at a tertiary center.
• Analysis of discrepancies based on patient age, performer, and CHD complexity.
• Validation of findings with surgical, CT, or cardiac catheterization data.

Main Results:

• Diagnostic errors occurred in 38% of echocardiograms.
• Moderate to major discrepancies affecting management were found in 23% of cases.
• Higher discrepancy rates were observed with non-pediatric cardiologist performers (P < 0.01) and complex CHD (P = 0.0001).
• No significant age-related difference in discrepancy rates was noted.

Conclusions:

• A substantial proportion of pediatric echocardiograms at non-tertiary centers contain discrepancies impacting clinical decisions.
• Echocardiogram performer expertise and CHD complexity are key factors influencing accuracy.
• Quality improvement initiatives are needed for non-tertiary pediatric echocardiography services.
