Radiation Safety in the Catheterization Laboratory: Current Perspectives and Practices

Area of Science:

• Medical Imaging
• Radiation Oncology
• Cardiovascular Interventions

Background:

• Significant variability exists in radiation safety protocols within cardiac catheterization laboratories worldwide.
• Cardiac catheterization procedures involve ionizing radiation, posing potential health risks to both patients and healthcare professionals.

Purpose of the Study:

• To assess current radiation safety practices and awareness among personnel in cardiac catheterization laboratories globally.
• To identify disparities in radiation safety knowledge and implementation across different geographic regions and professional groups.

Main Methods:

• An international online survey was conducted among interventional cardiologists, electrophysiologists, interventional radiologists, and vascular surgeons.
• The survey collected data on radiation safety awareness, training, personal dosimetry, protective measures, and health concerns.

Main Results:

• 570 responses were received, with most from the United States. A majority of respondents were unaware of their annual radiation dose and had not attended radiation safety courses.
• Concerns about chronic radiation exposure were high, with reported issues including back pain, cataracts, and malignancies. Only 37.5% had established radiation dose thresholds for patient follow-up.
• US operators demonstrated higher adherence to radiation safety practices, including wearing dosimeters, knowing their exposure, and utilizing protective equipment, compared to international counterparts.

Conclusions:

• Radiation safety is a significant concern for catheterization laboratory personnel, but practices are highly variable.
• There are clear opportunities to standardize and improve radiation protection measures and training in these settings.
• Enhanced awareness and adherence to radiation safety protocols are crucial for mitigating risks in interventional cardiovascular procedures.
