Control of the environment refers to measures that are built into health care settings that have been shown to reduce the risk of transmission of infection.
2 In occupational therapy practice, this includes taking measures to ensure that equipment, including supplies and devices, used in the delivery of services are cleaned and maintained appropriately. OTs must consider whether it is safe to reuse them with the same or different clients, under what circumstances reuse would be appropriate, and what cleaning and maintenance is required. Additionally, OTs must use their clinical judgement to determine when commonly used items such as pens or measuring tapes should be cleaned or discarded.
In addition to infectious agents, OTs should also be aware of other environmental factors such as insect infestations or food borne illness that may impact client health and safety during occupational therapy practice. This may include implications for transmission from environment to environment in community settings. OTs are responsible to ensure they have knowledge related to food safety when performing activities such as cooking assessments. Information regarding food safety and management of infestations is made available by Health Canada, Public Health Ontario and local public health units.
Classification of Equipment Used in Practice and Best Practices for Reprocessing Equipment
According to Public Health Ontario (PHO), the equipment used by health professionals in their practice can be classified in three different ways: non-critical, semi-critical, and critical.
3 Additionally, PHO refers to the steps taken to clean, disinfect, and sterilize medical equipment or devices as “reprocessing”. OTs must be knowledgeable about the different classifications of medical equipment as outlined by PHO and the best practices for cleaning, disinfecting or sterilizing them. OTs should adhere to the manufacturer’s instructions and/or guidelines to properly and regularly clean and/or disinfect equipment used in their practice setting.
The following chart outlines the classification system used by PHO and notes best practices for cleaning, disinfecting, and sterilizing them:
Classification of Equipment |
Definitions and Examples |
Best Practices for Reprocessing |
Non-Critical equipment or devices
|
Those that do not touch the client directly or they only touch the client’s intact skin.
Examples: splints, goniometers, blood pressure cuffs or stethoscopes.
|
Cleaning and may also require low-level disinfection or single use.
|
Semi-Critical equipment or devices
|
Those that come in contact with non-intact skin or mucous membranes, but do not penetrate them.
Examples: respiratory equipment or probes.
|
Meticulous cleaning followed by, at a minimum, high-level disinfection.
|
Critical equipment or devices
|
Those that enter sterile tissues.
Examples: indwelling catheter or footcare equipment.
|
Meticulous cleaning followed by sterilization.

Standard 4
The OT will incorporate current evidence-based infection prevention and control protocols for cleaning of the environment, and cleaning, disinfection and/or sterilization of equipment used in their practice setting.
Performance Indicators
An occupational therapist will:
4.1
Understand and apply evidence-based cleaning, disinfection and/or sterilization protocols for the physical environment;
4.2
Understand and apply evidence-based cleaning, disinfection and/or sterilization protocols for the devices and equipment used in their practice setting including:
4.2.1
Complying with the equipment manufacturer’s instructions for use;
4.2.2
Complying with best practices for the cleaning of equipment including non-critical equipment and devices, semi-critical equipment and devices, and critical equipment and devices. These best practices should be obtained from Public Health Ontario and the Provincial Infectious Diseases Advisory Committee. (See Appendix A);
4.3
Routinely review and update protocols pertaining to cleaning, disinfection, and/or sterilization of devices and equipment used in their practice setting as best practices for infection prevention and control evolve;
4.4
Maintain documentation as outlined in the protocols regarding the cleaning, disinfection, and sterilization of devices and equipment used in their practice.
