10. Reprocessing of reusable medical devices and other devices in general practice
Last revised: 12 Jun 2026
The Spaulding Classification Scheme categorises reusable medical devices based on their risk of infection transmission, and the necessary level of reprocessing required before reuse. Table 10.2 provides general criteria for the reprocessing and storage of reusable medical devices in general practice based on the Spaulding Classification.
In general practice, most devices are semi-critical or non-critical, as procedures are typically non-invasive or minimally invasive. Critical devices, which come into contact with sterile body tissues or the vascular system, are rarely used in general practice. The specific requirements for reprocessing critical devices are not included in this section. For detailed guidance on critical devices, refer to AS 5369 – Reprocessing of reusable medical devices and other devices in health and non-health related facilities.
Table 10.2 General criteria for reprocessing and storage of reusable medical devices
Level of risk
Process
Storage
Non-critical medical device
A medical device that comes into contact with intact skin but not mucous membranes
Clean as soon as possible after using
For further treatment, disinfect with compatible low-level or intermediate-level instrument grade disinfectant or thermal disinfection
Note: Some non-critical medical devices might not come into direct contact with a patient, eg a kidney dish or bowl. However, as the item is used within the patient environment there is potential for the item to become contaminated
Store in a clean, dry place to minimise environmental contamination
Semi-critical medical device
A medical device that comes into contact with mucous membranes or non-intact skin
Clean using a washer-disinfector as soon as possible after using
Sterilise by moist heat after cleaning
Manual and ultrasonic cleaning of reusable medical devices is only acceptable if the device’s validated cleaning instructions require manual cleaning or ultrasonic cleaning, or as a pre-treatment prior to cleaning in a washer-disinfector
Store to prevent environmental contamination in a designated storage system (e.g. dedicated clean cupboard or drawer, or a controlled environment drying cabinet)
Critical medical device
A medical device that is intended to be introduced directly into or have contact with the vascular system or normally sterile areas of the body
Note: A critical medical device contaminated with microorganisms confers a high risk of transmission of infectious agents
Pre-clean as above
If a reusable medical device is heat or moisture sensitive, sterilise using an alternative low-temperature sterilisation process
Refer to AS 5369 – Reprocessing of reusable medical devices and other devices in health and non-health related facilities
Sterility needs to be maintained
Integrity of the package needs to be maintained
Needs to be protected from environmental contamination and stored in a designated storage area
Reusable medical devices processed through a liquid chemical sterilisation process to be used immediately
