Infection Control in Ultrasound: Mitigating cross contamination risk

Available: On Demand

Current high level disinfection practices used in ultrasound practices come with a range of challenges including: exposure to harmful chemicals, inconsistent manual processes, and lack of effectiveness in eliminating microorganisms on the probe – including the handle.

In addition, recent research shows that disinfectants commonly used on ultrasound probes do not kill high-risk, cancer-causing HPV (Human Papillomavirus). 1 This webinar will provide detail regarding this new development that represents a new challenge for infection prevention that needs to be addressed. It will cover potential solutions to mitigate HPV transmission risk in the ultrasound environment, together with a sonographer’s experience of working with a solution to help overcome the challenges associated with current HLD methods.

trophon® EPR is an automated, environmentally friendly high level disinfection system that eliminates the use of harmful chemicals such as OPA.  It helps address many of the challenges associated with current disinfection practices.

Cath Murphy, Ph.D., Executive Director, Infection Prevention Plus, Past President, APIC, will provide an overview of current disinfection guidelines, common practices and associated challenges and risks.

Distinguished Professor Craig Meyers, Penn State College of Medicine will explain the clinical significance of HPV and the testing that has shown only one system to be fully effective against this difficult-to-kill virus.

Bob DeJong, RDMS, RVT, FSDMS, FAIUM, Radiology Technical Manager, Ultrasound from the Johns Hopkins Medical Institutions, will discuss the challenges faced with current ultrasound disinfection practices and his personal perspectives and experience in using trophon.

Session will be followed by Q&A.

 Craig Meyers Craig Meyers PhD

Craig Meyers is Distinguished Professor of Microbiology and Immunology at Penn State College of Medicine. He has co-authored more than 100 scientific research papers.

Professor Meyers’ recent work has involved studying the differentiation-dependent life cycle of human papillomavirus (HPV) and HPV-associated oncogenesis. His team is the first to grow native (natural, infectious) HPV in high enough quantities for laboratory testing.

He co-authored an important paper, published in the Journal of Antimicrobial Chemotherapy in 2014, that showed that disinfectants commonly used on ultrasound probes, such as glutaraldehyde and ortho-phthalaldehyde (OPA), do not work. The study also demonstrated the clinical importance of using native HPV for disinfectant and microbicide testing as opposed to surrogate viruses.

A follow up study carried out according to FDA test requirements, and presented at SHEA this year, demonstrated the ability of the trophon EPR device to completely inactivate HPV while demonstrating once again that OPA is not completely ineffective.

Professor Meyers’ recent awards include Postdoctoral Mentorship Award, Penn State (2010) and Alumni Achievement Award, Brigham Young University (2013).
