Minimize infection risks with thyroid shields

Thyroid shields are essential for protecting healthcare professionals from radiation exposure during imaging procedures. Yet, despite their critical role in radiation safety, many practitioners overlook the potential infection risks associated with these frequently shared pieces of equipment.  

The Centers for Disease Control and Prevention (CDC) estimates nearly one million lives are lost yearly due to hospital-acquired infections. A significant contributor to this staggering number is bacteria’s ability to survive for long periods on common medical surfaces and fabrics—including fabric-covered thyroid shields. Understanding the protective and hygienic aspects of thyroid shields is vital to safeguarding staff and patients. 

Why Thyroid Shields Require Special Attention

Thyroid shields, particularly those containing lead or lead-equivalent material, are routinely shared among radiology staff, increasing the likelihood of cross-contamination. The area where these shields rest—the collarbone and neck—is prone to skin-borne infections. Pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) can survive on surfaces for extended periods, underscoring the need for rigorous infection control measures. Without adequate cleaning protocols and effective barriers, thyroid shields may inadvertently serve as a reservoir for these harmful microorganisms. 

A 2021 Lead Apron Contamination Study conducted in dental clinics further highlights this risk—researchers identified 26 strains of bacteria on thyroid collars, even after routine disinfection with chemical wipes. These findings demonstrate that conventional cleaning methods can fall short, emphasizing the need for higher standards that address both radiation protection and infection prevention. 

Choosing a High-Quality Thyroid Shield for Hygiene and Protection

AliMed Thyroid Shields are designed to meet strict hygiene requirements while delivering effective radiation protection. The Ultralight Disposable Thyroid Shield is the only single-use, disposable thyroid collar available in the United States, offering a hassle-free solution for maintaining exceptional cleanliness.   

For those who prefer reusable options, AliMed's Fluidproof Thyroid Shields are crafted with an antimicrobial agent embedded in the fabric that inhibits microbial growth and neutralizes odors. This construction ensures a high-quality product that significantly reduces the risk of infection while providing superb radiation protection. 

Keeping Cross-Contamination Under Control

Reducing infection risks requires a proactive, multifaceted approach. While strict cleaning protocols are essential for reusable lead thyroid collars, emerging evidence suggests that even thorough chemical disinfection can leave behind bacterial contaminants. Adopting next-generation solutions, such as single-use thyroid shields or those treated with antimicrobial agents, is critical in limiting cross-contamination and protecting both healthcare workers and patients. 

Thyroid shields are critical in minimizing radiation exposure, but their importance in preventing infection must not be overlooked. By employing high-quality, innovation-driven solutions, clinical environments can reduce the risk of harmful cross-contamination.
