Abstract

Canadian hospitals were made aware of the risk of Mycobacterium chimaera infection associated with heater-cooler units (HCUs) through alerts issued by the US food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention (CDC). In response, most hospitals conducted retrospective reviews for infections, informed exposed patients, and initiated a requirement for informed consent with HCU use.
