Implementing Patient Protection Radiation Dose Alerts for Pediatric Cardiac Catheterization Examinations

Area of Science:

• Pediatric Cardiology
• Medical Imaging
• Radiation Safety

Background:

• Cardiac catheterization improves survival in pediatric congenital heart disease.
• Ionizing radiation during these procedures poses ethical risks.
• Minimizing radiation exposure is crucial for patient safety.

Purpose of the Study:

• To develop an empirical model for establishing radiation dose alert levels in pediatric cardiac catheterization.
• To tailor dose monitoring to individual patient characteristics and procedure types.
• To reduce radiation overexposure events in pediatric patients.

Main Methods:

• Developed a model using data from 3131 pediatric cardiac catheterization procedures.
• Utilized linear regression of logarithmic reference air kinetic energy released per unit mass (KERMA) and dose area product.
• Established alert levels at the 95th and 99th percentiles based on patient lateral thoracic thickness.

Main Results:

• Provided regression coefficients for diagnostic and interventional procedures across different fluoroscopic planes.
• Enabled facilities to adapt the model to their specific practice and patient population.
• Demonstrated a method for scaling single-facility data to broader applications.

Conclusions:

• The proposed model allows institutions to customize radiation dose alert levels for pediatric patients.
• This tailored approach helps in reducing instances of radiation overexposure.
• Facilitates safer cardiac catheterization practices for children.
