Reported practice patterns in the ambulatory care setting for patients with CHD

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease Management
• Healthcare Practice Variability

Background:

• Lack of evidence-based guidelines leads to varied monitoring practices among pediatric cardiologists for asymptomatic patients with congenital heart defects.
• Variability in practice may stem from personal, institutional, and financial factors, impacting care quality and costs.
• Focus on asymptomatic tetralogy of Fallot and d-transposition of the great arteries highlights common scenarios in pediatric cardiology ambulatory care.

Purpose of the Study:

• To describe self-reported practice patterns of pediatric cardiologists in monitoring specific congenital heart conditions.
• To investigate physician attitudes towards factors influencing diagnostic testing strategies.
• To identify potential areas for reducing practice variability and associated healthcare costs.

Main Methods:

• A cross-sectional survey was administered to pediatric cardiologists at a Continuing Medical Education conference and a single center.
• The survey collected data on physician characteristics, self-reported testing frequencies, and attitudes towards ordering echocardiograms.
• Vignettes depicting common clinical scenarios were used to assess testing decisions.

Main Results:

• A majority of surveyed cardiologists reported consistent annual physical exams, ECGs, and echocardiograms for patients regardless of age or disease severity.
• Less frequent and less consistent use of other tests like Holter monitors, exercise stress tests, and cardiac MRIs was observed.
• Younger physicians were more likely to be high-frequency testers in scenarios involving younger children with milder disease.

Conclusions:

• The study indicates potential variability in pediatric cardiology practice patterns that warrants further investigation in real-world settings.
• If clinical outcomes are comparable between low-frequency and high-frequency testers, practice modifications could lower costs without compromising care quality.
• Further research is needed to validate these findings and inform evidence-based guidelines for monitoring congenital heart disease patients.
