Guidelines for Reprocessing Ultrasound Transducers: 2026

Abstract

Introduction

Ultrasound equipment is recognised as a potential source of harmful microorganisms which could lead to clinical infection. This highlights the importance of standardised infection prevention and control strategies for ultrasound practice across Australia and New Zealand. This revised guideline supersedes the similarly named 2017 guideline and was collaboratively developed by the Australasian Society for Ultrasound in Medicine (ASUM) and the Australasian College for Infection Prevention and Control (ACIPC).

Methods

A multidisciplinary working group was assembled consisting of ultrasound practitioners from varying specialty areas and infection control specialists. The guideline recommendations were informed by a review of relevant literature, national and international standards, and current Australian and New Zealand regulatory requirements. A catalyst for the revision of these guidelines was the release of the Australian Standard AS5369:2023—Reprocessing of reusable medical devices and other devices in health and non-health related facilities. Consensus was achieved through structured discussions and iterative drafting including wider stakeholder feedback.

Results

Recommendations for transducer reprocessing were based on the invasiveness of the ultrasound transducer as well as the type of human tissue it contacted during use. Particular attention is also given to the safe use of ultrasound gel, transducer covers, as well as broader considerations of standard and transmission-based precautions, including the use of aseptic technique.

Conclusion

Implementation of this guideline by ultrasound clinicians and their facilities will reduce the risk of transmission of potentially harmful microorganisms and ensure infection prevention and control practices across Australia and New Zealand are aligned with accepted national standards.

Impact Statement

This guideline outlines the Australian and New Zealand standard for infection prevention and control as it relates to ultrasound practice. This 2026 revision supersedes the similarly named 2017 guideline and was collaboratively developed by the Australasian Society for Ultrasound in Medicine (ASUM) and the Australasian College for Infection Prevention and Control (ACIPC). The multidisciplinary working group used published literature, national and international standards, and relevant regulatory requirements in formulating the recommendations. This guideline should be used by clinicians and facilities using ultrasound to reduce the transmission of potentially harmful microorganisms and improve patient care.
