Guidelines referenced in this toolkit are evidence based, have been developed with infection prevention representation and have followed a formal guideline development process, including a public comment period. These tools are intended to guide the development of institutional policies and procedures, with an understanding that each institution can vary in the patient groups cared for, settings and the types of care provided. Toolkit ContentsTool 1: Part A - LocateThis list of strategies can help locate ultrasound machines in your facility. Locating ultrasound machines can be a challenging task, as they may move around, be uncatalogued, or may be unknown to personnel with responsibility for probe use and reprocessing. Tool 1: Part B - ProfileAfter locating ultrasound machines with the Locate tool, this audit tool can be used to observe and assess procedure-specific ultrasound policy and practice. First record the procedure and department, then work through the profile form. The questions guide the user through their policy and an observation checklist is provided to record actual practice. The tool leads the user to an action plan if there is no policy, or if there are discrepancies among policy, practice and guidelines.Tool 2: AlgorithmThis tool is organized by department and provides a range of typical procedures that may be encountered in that department.

The flow chart can be printed out and displayed throughout office and procedure rooms, and used as a quick reference chart for healthcare workers to determine whether practice is compliant with available guidelines.Tool 3: Example Risk AssessmentThis tool contains four editable templates designed to guide the assessment of potential hazards that may be encountered during the use and reprocessing (cleaning, disinfection, storage) of ultrasound probes. A sample risk matrix is provided with further instructions for completion. A facility should aim to mitigate all significant harm to the lowest risk rating. If that is not possible, the existing workflow and/or products should be reconsidered.Tool 4: Policy Development FrameworkThis tool is a policy development framework designed to help develop infection prevention policies for all settings where ultrasound technology is used and probes are reprocessed. It can be used to develop a universal hospital policy or a department specific policy and has been developed based on major guidelines,4-6 standards1-3 and evidence based scientific literature.FundingThe development of this toolkit has been supported by Nanosonics Ltd.

The probe MIFU should always be consulted for cleaning instructions and lists of compatible products. Typical cleaning solutions indicated for use with ultrasound probes include detergent-based cleaning wipes, detergent in combination with running water and enzymatic cleaning agents. The cleaning method should be indicated for use on ultrasound probes, be effective, be compatible with the probe and be safe for the user. Ensure appropriate PPE is available for staff to undertake the cleaning process. Perform rinsing if required by the MIFU of the cleaning product. At the conclusion of the cleaning process, the probe should be dried to prevent interference in subsequent steps.According to Australian Standards2,3 and NHMRC Guidelines ADDIN EN.CITE <EndNote><Cite><Author>National Health and Medical Research Council</Author><Year>2010</Year><RecNum>34</RecNum><DisplayText><style face="superscript">5</style></DisplayText><record><rec-number>34</rec-number><foreign-keys><key app="EN" db-id="tt5t5afvaexr2ke2daavwd0n2fpdx0x292ve" timestamp="1540162877">34</key></foreign-keys><ref-type name="Government Document">46</ref-type><contributors><authors><author>National Health and Medical Research Council,</author></authors></contributors><titles><title>Australian Guidelines for The Prevention and Control of Infection in Healthcare</title></titles><dates><year>2010</year></dates><pub-location>Canberra</pub-location><publisher>Commonwealth of Australia</publisher><urls></urls></record></Cite></EndNote>5 at a minimum, all instruments should be individually inspected and be visibly clean before the device is disinfected or sterilized. -21265-172800Note the cleaning process used in your department/facility and reference or specify the standard operating procedure (SOP) here. 5.2 Disinfection and Sterilization5.2.1 Assigning the Spaulding Classification of the ProbeEach ultrasound probe should be classified according to the Spaulding criteria based on its intended use. Medical devices can be classified into three categories based on the patient tissues they contact and associated infection transmission risk. The Spaulding classification system dictates the level of disinfection/sterilization required for the ultrasound probe.2-6 Non-critical ultrasound probes Will only contact healthy intact skin, will not contact mucous membranes, the bloodstream or sterile tissues. Require a minimum of low or intermediate -level disinfection (LLD or ILD) with a TGA-registered disinfectant.4Example procedures where the ultrasound probe is non-critical include abdominal scans on healthy skin and other non-invasive ultrasounds.Semi-critical ultrasound probes Contact mucous membranes or non-intact skin (e.g., skin with abrasions, dermatitis, chapped skin, rash, psoriasis). Semi-critical probes do not contact sterile tissues or the bloodstream.Require a minimum of high-level disinfection (HLD)4,5 so that the device is free from all microorganisms except for a small number of bacterial spores.Example procedures where the ultrasound probe is semi-critical include:Endocavitary ultrasound of healthy mucosa (e.g., transvaginal, transrectal, transesophageal echocardiography scans) Abdominal or other diagnostic scans on non-intact skinSurface wound assessment (e.g., partly healed wound)In the event semi-critical ultrasound probes are used in conjunction with a sheath, the probe still requires HLD.

Require sterilization to be free from all viable microorganisms.In general, critical ultrasound probes include those used in surgical procedures and some ultrasound guided interventions (e.g., percutaneous procedures where the probe can contact the puncture site). These invasive procedures require a sterile field and sterile instrumentation as they access sterile body sites. Standards Australia state specifically that reusable critical medical devices shall be reprocessed to the highest possible level between uses and in accordance with MIFUs.2 The ACIPC/ASUM Guidelines4 specify that critical ultrasound probes that are delicate and heat sensitive, may be reprocessed by high-level disinfection. However, an appropriate sterile sheath or transducer cover must also be used. 0532Figure 2. A flowchart decision tree to determine the level of reprocessing and sheath type required before use of an ultrasound probe on a patient. 0Figure 2. A flowchart decision tree to determine the level of reprocessing and sheath type required before use of an ultrasound probe on a patient. -23812532639000Apply the above rationale to the procedures used in your department/facility. List the procedures performed and assign the Spaulding classification of the probe and sheath and reference or specify the SOP here. 5.2.2 Methods of Disinfection and SterilizationCleaning is a critical requirement prior to any disinfection or sterilization process.2,5 It is important to ensure that sterilization or disinfection is compatible with the ultrasound probe such that probe integrity is not compromised. Cleaning agents and instrument-grade HLD methods must be TGA-approved for medical devices and be currently listed on the Australian Register of Therapeutic Goods (ARTG).4 right26162000Note the disinfection/sterilization process used in your department/facility and reference or specify the SOP here. 5.2.3 Validation All manual or automated reprocessing steps (cleaning, disinfecting, packing or sterilizing processes) must be validated according to AS/NZS 4187.2 This requires an installation qualification (IQ), operational qualification (OQ), performance qualification (PQ) and routine monitoring and control.2 Installation qualification (IQ)The purpose of IQ is to demonstrate that the equipment supplied to perform reprocessing and the environment in which the equipment is installed (services qualification, e.g. water quality), comply with the manufacturer’s installation specifications.2 IQ is undertaken by the supplier of the equipment.2 Operational qualification (OQ)The purpose of OQ is to demonstrate the capability of the equipment to deliver the reprocessing endpoints defined by the MIFU, and is also undertaken by the manufacturer. This is performed without a load, or with a defined test material. OQ is performed immediately after installation, relocation, modification, service change or repair.2Performance qualification (PQ)The purpose of PQ is to demonstrate that reprocessing endpoints are met with device loads intended to be reprocessed by the health service organization. Physical performance qualification (PPQ) and microbiological performance qualification (MPQ) are required to be performed by the organization. PPQ requires validation that critical physical parameters are achieved, and MPQ requires validation of the microbiological lethality of the process. PQ is performed immediately after IQ and OQ, relocation, modification, service change or repair.2 Routine monitoring and controlThe purpose of routine monitoring and control is to ensure the validated processes for the device are delivered to the actual device at every reprocessing cycle. Types of monitors are shown in Figure 3. The MIFU should be followed to determine monitor type, frequency, placement and interpretation of results.2764473121777Figure 3. A summary of different types of monitors which can be employed for process validation.00Figure 3. A summary of different types of monitors which can be employed for process validation.As part of cycle validation, ensure monitor results are documented and stored to facilitate traceability. Also ensure staff are trained regularly in their use and interpretation.2,4-5715025209500Note the validation processes required in the MIFU for your disinfection/sterilization process and reference or specify the SOP here. 5.2.4 Inadequate Reprocessing If a reprocessing cycle fails, ensure the probe is not used on the patient and follow the procedure for non-conformance outlined in Section 2.5 of AS/NZS 4187:2014 (Incorporating Amendment No. 1) Reprocessing of reusable medical devices in health service organizations2 and Section C4.2.3 Critical incidents in the NHMRC Australian Guidelines for The Prevention and Control of Infection in Healthcare.5 In the event of multiple reprocessing cycle failures, the following may provide a pragmatic approach to resolving the issue and ensuring patient safety is not compromised.1. Refer to the disinfectant/sterilization MIFU to troubleshoot. If troubleshooting unsuccessful, document and report the process/device and nature of failure, and remove from service.2. Head of department, risk management, or infection control department and others per local protocol should be immediately notified. An investigation should be conducted to assess any patient harm, and decision made regarding patient notification.3. After the problem is corrected the process/device should be thoroughly validated (via a range of monitors and/or diagnostic cycles) and in accordance with AS/NZS 4187:2014 (Incorporating Amendment No. 1) Reprocessing of reusable medical devices in health service organizations2 before being returned to service.left-8626400Note disinfection/sterilization process specific steps required in the event of a reprocessing failure at your facility here or reference the SOP.5.2.5 Rinsing and Dryingleft102108000Sterilization in terminal barriers does not require any rinsing or drying. For liquid chemical sterilization or high-level disinfection, refer to the MIFU to determine rinsing and drying requirements. Determine the number of rinses (if required), the quality of rinse water that should be used (e.g., potable, deionized, sterile) and drying method (e.g., clean, lint free towel or wipe or air dry).List requirements here or reference SOP.5.2.6 Transport & StorageIf the reprocessing workflow requires probe transportation, the following requirements should be met (adapted from ACIPC/ASUM Guidelines) ADDIN EN.CITE <EndNote><Cite><Author>Australasian College of Infection Prevention and Control</Author><Year>2017</Year><RecNum>1</RecNum><DisplayText><style face="superscript">4</style></DisplayText><record><rec-number>1</rec-number><foreign-keys><key app="EN" db-id="tt5t5afvaexr2ke2daavwd0n2fpdx0x292ve" timestamp="1501805407">1</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author><style face="normal" font="default" size="10">Australasian College of Infection Prevention and Control and Australasian Society for Ultrasound Medicine,</style></author></authors></contributors><titles><title>Guidelines for Reprocessing Ultrasound Transducers</title><secondary-title>Australasian Journal of Ultrasound in Medicine</secondary-title></titles><periodical><full-title>Australasian Journal of Ultrasound in Medicine</full-title></periodical><pages>30-40</pages><volume>20</volume><number>1</number><section>30</section><dates><year>2017</year></dates><isbn>18366864</isbn><urls><related-urls><url>: Reprocessing can be performed at the point of care (POC) or in a separate room. The products used must be safe to use in that setting. If reprocessing is performed in another room, a system for transducer transport must be implemented to ensure dirty and clean transducers remain separated. Ideally the workflow would be uni-directional.Separate transport containers for dirty and clean transducers are required.According to Standards Australia, reprocessed medical devices must be stored in a manner that prevents environmental contamination.2 Ideally reprocessed probes can be stored in a specific cabinet or on the console with a clean room manufactured storage cover. All items must be stored in a way that that maintains their level of reprocessing.

Ensure above requirements are met and specify methods and information that needs to be collected, linked, stored and maintained. 6. During an Ultrasound procedureleft7175500This section expands on probe barrier use and specifies gel use requirements based on the Spaulding classification of the ultrasound probe. This rationale should be applied to each procedure in your facility/department and specified.6.1 GeneralIt is important to ensure all equipment necessary for the procedure is adequately reprocessed before use. Additionally, proper protocols should be used to prevent cross-contamination between surfaces, probes, operators and the patient. It is also important to remember that unexpected changes in patient circumstances may occur and will require considering whether the selected probe is still appropriate for the upcoming procedure. For example, the patient may present with non-intact skin (e.g., dermatitis, rash or wound) when intact skin was expected. This would make the probe semi-critical instead of non-critical and will consequently require HLD versus LLD. See Disinfection and Sterilization for assigning the Spaulding classification to the probe.6.2 Probe Barriers Probe sheaths (e.g., dedicated covers, condoms) are an additional layer of protection to prevent excessive soiling and to minimize the chance of cross contamination between patients. Sheaths are available sterile and non-sterile (usually clean-room manufactured). Condoms are typically non-sterile.NHMRC and ACIPC/ASUM guidelines require semi-critical probes (e.g. intracavity probes) to undergo high level disinfection and be used with a single use sheath.4,5 They require critical probes undergo sterilization, and if this is not possible, the probe should minimally undergo HLD and be used with a sterile sheath.4 Studies have demonstrated the high frequency of probe sheath perforation rates, occurrences of probe sheath contamination post procedure and difficulties involved with visually determining probe sheath breaches and perforations.7-13 Standards Australia state that: “Single use sheaths/ sleeves/ protective barriers...shall not be used as a substitute for cleaning, disinfection or sterilization.”2,3 See Disinfection and Sterilization for assigning the Spaulding classification to the probe and the associated cover use.6.3 Gel Use Ultrasound coupling gel is necessary to allow passage of the ultrasound energy into patient tissues and is required for a good quality image. It is used in almost all ultrasound procedures. As such, policy describing safe handling and use is paramount to reducing and preventing cross contamination. Numerous outbreaks from contaminated ultrasound gel have been reported in the literature.14-18 In some cases these infections have been associated with invasive procedures such as ultrasound guided central venous catheter placement, pericardiocentesis, amniocentesis and surgeries. Gel is typically available in single-use sachets (sterile and non-sterile) as well as in non-sterile multi-use gel bottles. Careful selection of the correct type of gel is important for preventing infections. A rationale for sterility requirements for gel use can be derived from the Spaulding classification. For critical and semi-critical items, sterile gel should be used, for non-critical a minimum of multi-use gel can be used (Table 2).4After completion of the procedure, the probe should be immediately cleaned and all visible gel and bioburden removed before subjecting the probe to subsequent reprocessing steps. Relevant staff should be educated regarding the use of probe covers and ultrasound coupling gel and competency regularly checked. Table 2. Ultrasound gel use during ultrasound guided proceduresCritical probesSemi-critical probesNon-critical probes Sterile single use gel Sterile single use gel Multiuse, non-refillable gel acceptableConsiderationsConsiderationsConsiderations Use aseptic technique when handling Sterile single use gel is the minimum requirement for invasive procedures where there is risk of the probe and gel contacting sterile tissue and blood or where an aseptic field is in use. Use aseptic technique when handling Sterile single use gel is the minimum requirement for procedures where there is risk of the probe and gel contacting intact mucous membranes or non-intact skin. Avoid multiuse gel where possible, single use gels preferred. If used, care should be taken not to touch the patient or probe with the tip of the multi-use gel bottle. Discard multiuse bottles based on facility policy and MIFU. Refillable bottles should be avoided due to established risk of bacterial growth. Generally gel warming should not be used due to the risk of pathogen growth.General considerations (all gel)Ensure gel is only used within its shelf lifeStore gel protected from sources of contamination (e.g., dust, moisture)Check before use for visual evidence of contamination7. Staff and Responsibilities The levels of staff and corresponding reprocessing responsibilities may vary depending on the size and structure of healthcare facilities. According to Standards Australia and the NHMRC, assigning responsibility is important for accountability and effective patient safety.2,5 7.1 Supervisory PersonnelSupervisory personnel oversee all reprocessing and use activities described in this policy. Standards Australia recommends they are trained in instrument reprocessing; participate in continuing education programs on management (personnel, material, financial) and leadership; participate in other courses related to the management position, with special emphasis on infection prevention and control, safety, and the principles and methods of reprocessing. Supervisory personnel should also have knowledge of relevant local, state and federal regulations and relevant qualifications (e.g., reprocessing certification).

Furthermore, they should have knowledge of general sterilization/disinfection and infectious disease transmission principles and aspects of liquid/chemical sterilization/HLD (if relevant), such as:Reprocessing Inspection of cleaning, drying and rinsing processes, Monitoring of sterilization/HLD processes,Maintaining documentation for traceability purposes, Safety with regard to using the equipment and personal hygiene, and, Use of PPE (where relevant) to protect skin, eyes, mucus membranes and clothing. 2,5left91059000Processing personnel are also required to participate in ongoing training programs which focus on orientation into the healthcare facilities and their departmental policies, infection prevention and control, use of reprocessing equipment, safety, attire, personal hygiene and compliance with local, state and national regulations. Specify reprocessing personnel (profession level) at your facility/department here.7.3 TrainingStaff involved in reprocessing and ultrasound equipment usage should receive orientation training prior to commencing responsibilities. Additionally, annual re-training should be performed for the duration of their employment. Training should establish the knowledge base required to safely perform reprocessing, safely use ultrasound in procedures, with the goal of removing operator error, promoting staff and patient safety and ultimately mitigating infection transmission risks.PEVuZE5vdGU+PENpdGU+PEF1dGhvcj5BdXN0cmFsYXNpYW4gQ29sbGVnZSBvZiBJbmZlY3Rpb24g

Evaluating changes to products & processesAll aspects of this policy should be reviewed with infection prevention and other relevant subject matter experts when setting up the use of ultrasound for the first time, purchasing new ultrasound equipment or making changes to existing processes. Additional considerations are:Safety – The NHMRC guidelines and Australian Standards require staff and patient safety must not be compromised by the chosen reprocessing workflows and processes.2,5 Consider chemical exposure risks from bulk liquids and vapors. Work area design considerations must be assessed (e.g., ventilation, designated dirty/clean sinks, hazardous waste disposal units, emergency showers) if required. Cost –Cost-effectiveness factors that should be evaluated related to equipment (e.g., purchase, service and maintenance), consumables, PPE, energy, disposal costs and training).Reprocessing time – Consider time required to examine patients versus time for reprocessing. If there is high patient turnover it may be necessary to change the reprocessing procedure or purchase additional probes for effective turnaround time. Reprocessing location – If probes are reprocessed at point of use, then the disinfection method must be safe for patients and staff. Standards Australia and ASUM/ACIPC Guidelines require a dirty to clean workflow during reprocessing.2,4 This should be observed regardless of reprocessing location with designated dirty and clean areas to prevent cross contamination. If transport of dirty or clean devices is required to a central reprocessing area, then a probe transportation protocol must be observed to prevent mixing of dirty and clean instruments (See Transport and Storage). Automated or manual reprocessing – Consideration should be given to automated versus manual processes. It is well accepted that automated processes minimize the influence of human factors on reprocessing outcomes and should be adopted where possible.199.
