Survey on ultrasound cleaning knowledge (SUCK)

Area of Science:

• Medical Imaging
• Infectious Disease Control
• Respiratory Medicine

Background:

• Point of Care Ultrasound (POCUS) is increasingly used in respiratory medicine for rapid diagnosis and safe pleural procedures.
• The potential for POCUS devices to act as vectors for pathogen transmission requires careful consideration.
• Current POCUS training curricula often lack comprehensive education on proper cleaning protocols.

Purpose of the Study:

• To assess the knowledge and practices of respiratory medicine practitioners regarding POCUS cleaning procedures.
• To identify gaps in education and awareness of POCUS cleaning guidelines among healthcare professionals.

Main Methods:

• A survey was administered to respiratory medicine practitioners across Australian teaching hospitals.
• The survey, using an adjusted, accepted instrument, collected data on POCUS usage and cleaning knowledge/practices.
• Data was collected anonymously via the REDCap platform between August and November 2024.

Main Results:

• 62% of 66 respondents reported never receiving education on ultrasound machine cleaning.
• While most identified appropriate cleaning products, some incorrectly suggested harsh methods for probe cleaning (21% alcohol, 3% high-temperature sterilization).
• Lack of knowledge and access to materials were primary reasons for inadequate cleaning.

Conclusions:

• Formal POCUS training is common, but knowledge of appropriate cleaning procedures is significantly lacking.
• There is an urgent need to enhance awareness and implementation of POCUS cleaning guidelines.
• Addressing these gaps is essential to mitigate the risk of healthcare-associated infections transmitted via POCUS devices.
