Exposure of cardiologists from interventional procedures

Area of Science:

• Medical Physics
• Cardiology
• Radiation Safety

Background:

• Interventional cardiology involves significant radiation exposure for both physicians and patients.
• Variability in radiation exposure among cardiologists performing similar procedures necessitates investigation.

Purpose of the Study:

• To evaluate and quantify the radiation exposure differences among seven cardiologists during interventional procedures.
• To determine the relationship between cardiologist radiation exposure and patient radiation exposure.
• To identify factors influencing cardiologist radiation dose.

Main Methods:

• Collected radiation exposure data for seven cardiologists and over 10,000 patients undergoing interventional procedures.
• Analyzed the correlation between cardiologist exposure (mSv) and patient exposure (Gy cm²) over a 4-week period.

Main Results:

• A linear relationship was observed between cardiologist and patient radiation exposure (R² = 0.55).
• Cardiologist exposure varied from 0.43 to 2.85 mSv in 4 weeks.
• Patient exposure ranged from 1633 to 5943 Gy cm² in 4 weeks.

Conclusions:

• Cardiologist radiation dose is primarily associated with the number of procedures performed, not their complexity.
• Optimizing radiation exposure techniques is recommended to minimize cardiologist radiation doses.
