Free Webinar – A Case Series of High-Risk Diversion Investigations Utilizing Bloodborne Pathogen Testing



Type of event:


The Tennessee Department of Health developed a collaborative investigative process to determine the risk of bloodborne pathogen transmission from licensed healthcare workers engaging in drug diversion. We then recommend public health action and provide consultation to improve drug diversion programs, including bloodborne pathogen testing, external language for employment verification, and inclusion of infection preventionists on drug diversion teams.
