Key Definitions
Accreditation Canada: Accreditation Canada is a not-for-profit, independent organization accredited by the International Society for Quality in Healthcare (ISQua). It provides national and international healthcare organizations with an external peer review process to assess and improve the services they provide to their patients and clients based on standards of excellence. More information is available at www.accreditation.ca.
Additional Precaution Daily Clean: daily cleaning and disinfection process for rooms/cubicles/spaces where patients are on additional precautions.
additional precautions: interventions implemented for certain pathogens or clinical presentations, in addition to routine infection control practices, to reduce the risk of transmission of microorganisms from patient to patient, patient to healthcare provider, and healthcare provider to patient.
airborne precautions: interventions to reduce the risk of transmission of microorganisms through the inhalation of airborne droplet nuclei or dust particles containing an infectious agent. airborne precautions include placing the patient in a negative pressure room and the use of N95 respirators and other personal protective equipment (gowns, gloves, face shields), as directed by the signage of the facility, when giving direct care to patients or when in contact with their environment.
alcohol-based hand Rub (ABHR): a liquid, gel, or foam formulation of alcohol (e.g., ethanol, isopropanol) that is used to reduce the number of microorganisms on hands in clinical situations when the hands are not visibly soiled. ABHRs contain emollients to reduce skin irritation and are less time-consuming to use than washing with soap and water.
antibiotic-resistant organism (ARO): a microorganism that has developed resistance to the action of several antimicrobial agents and that is of special clinical or epidemiological significance.
antiseptic: an agent that can kill microorganisms and is applied to living tissue and skin.
audit: a systematic and independent examination to determine whether quality activities and related results comply with planned arrangements, are implemented effectively, and are suitable to achieve objectives.
automatic dispensing system: systems that provide computer controls (automation) for preparation of cleaning or disinfectant solutions. These systems replace the need for manually measuring a quantity of cleaning or disinfectant products and water.
biomedical waste: contaminated, infectious waste from a healthcare setting that requires treatment prior to disposal in landfill sites or sanitary sewer systems. Biomedical waste includes human anatomical waste; human and animal cultures or specimens (excluding urine and feces); human liquid blood and blood products; items contaminated with blood or blood products that would release liquid or semi-liquid blood if compressed; body fluids visibly contaminated with blood; body fluids removed in the course of surgery, treatment or for diagnosis (excluding urine and feces); sharps; and broken glass which has come into contact with blood or body fluid.
British Columbia Provincial Infection Control Network (PICNet): PICNet is a provincial program of the Provincial Health Services Authority with a specific interest in the prevention and control of healthcare-associated infections. PICNet works together with partners on province-wide surveillance, development, and promotion of evidence-based best practices, and the creation of educational and operational tools. More information is available at www.picnet.ca.
IPAC-Canada: Infection Prevention and Control Canada is a professional organization of persons engaged in infection prevention and control activities in healthcare settings. IPAC-Canada members include infection prevention and control professionals from a number of related specialties including nurses, epidemiologists, physicians, microbiology technologists, public health, and industry.

This can also apply to staff when they are specifically assigned to care only for patients known to be colonized or infected with the same organism.
construction clean: cleaning performed by construction workers at the end of a workday or completion of a project that removes visible soil and dirt, construction materials, and workplace hazards.

- Contact: intended to prevent transmission of infectious agents, including epidemiologically important microorganisms, that are spread by direct or indirect contact with the patient or the patient’s environment.
- Droplet: intended to prevent transmission of pathogens spread through close respiratory or mucous membrane contact with respiratory secretions.
- Airborne: intended to prevent transmission of infectious agents that remain infectious over long distances when suspended in the air (e.g., rubeola virus [measles], varicella virus [chickenpox], M. tuberculosis, and possibly SARS-CoV).
