Radiation Safety (Still) Matters

In February, ACVP blog reported on a survey that showed non-physician Cath Lab employees, ACVP members, reporting higher levels of musculoskeletal pain due to radiation exposure and lead apron use.

In April, SCAI released a membership survey with almost 50 percent of responders reporting orthopedic injuries, and there has been "no discernible improvement" since a similar survey was collected in 2004.

There's more bad news. A new study published this week links radiation in the Cath Lab to subclinical atherosclerosis. That's right, working in the Cath Lab can cause cardiovascular disease.

The study calculated a radiological risk score based on proximity to radiation source, caseload, and the length of employment, and there was a significant correlation between this measure and carotid intima-media thickness on the left side, not on the right, which provides "further support for a causal connection."

What's being done?

In 2011, the Society of Cardiovascular Angiography and Interventions published new guidelines for a Radiation Safety Program for the Cardiac Catheterization Laboratory.

With regards to procedures, they recommended limiting exposure duration, reducing dosage, limiting high-dose high contrast use, reducing magnification, and increasing distance from the x-ray beam to name a few.

Mayo Clinic reduced doses by 40 percent over a 3-year period in a case study released in 2012, where researchers noted that "the physician's expectations [had to] change from a desire for excellent image quality to a desire for low radiation dose and acceptance of clinically adequate image quality."

Technology itself might not be able to change culture, but it can significantly improve many relevant factors, as demonstrated by trials and testimonials of Corindus's CorPath system.
