Efforts to Attenuate the Spread of Infection (EASI): a prospective, observational multicentre survey of ultrasound equipment in Australian emergency departments and intensive care units

Background and objectives: Ultrasound is a common and necessary part of acute care medicine, but may present an infection risk to patients secondary to transfer of infectious agents between patients. Our primary objective was to detect blood contamination on ultrasound equipment in emergency departments (EDs) and intensive care units. Secondary objectives included detection of microbial contamination and determination of factors associated with contamination
