What are routine practices?
Routine practices are a set of infection control strategies and standards designed to protect workers from exposure to potential sources of infectious diseases. Routine practices are based on the premise that all blood, body fluids, secretions, excretions, mucous membranes, non-intact skin or soiled items are potentially infectious. These practices, while mainly adopted by healthcare providers, apply to all professions in which workers may become exposed to infectious microorganisms through contact with blood and body fluids. Examples of these professions include police officers, trauma/crime scene clean-up crew, zookeepers, laboratory technicians, and embalmers.
Are routine practices different from universal precautions, body substance isolation, and standard precautions?
Universal precautions are a set of strategies developed to prevent of transmission of blood borne pathogens. The focus of universal precautions is on blood and selected body fluids such as cerebrospinal fluid, pleural fluid, and amniotic fluid. Body secretions such as urine, vomitus, feces, or sputum are not controlled under universal precautions, and are instead usually covered under a set of guidelines called body substance isolation.
Routine practices are a combination of universal precautions and body substance isolation. Routine practices have a much bigger scope and aim to protect against the transmission of all microorganisms through contact with all body fluids, excretions, mucous membranes, non-intact skin and soiled items in addition to precautions for blood.
Standard precautions is a term widely adopted in the United States and convey the same set of principles as routine practices.
What are the components of routine practices?
There are 5 major components to routine practices. They are risk assessment, hand hygiene, personal protective equipment, environmental and administrative controls.
Before any task is performed, conduct a risk assessment to evaluate the risk of disease transmission. The risk assessment should take into account the following:
- Time it takes to complete the task.
- Type of body fluids that the worker may come into contact with.
- Presence of microorganisms in the bodily fluids.
- Route of potential exposure to these microorganisms.
- Susceptibility of the worker to these microorganisms.
- Environment in which the task is carried out.
Appropriate strategies such as hand hygiene, waste management, and the use of personal protective equipment are then selected to reduce the risk of exposure and disease transmission.
The Ontario Ministry of Health and Long-Term Care suggest the following questions for healthcare providers to ask while assessing the risk:
1. What task am I going to perform?
2. What is the risk of exposure to:
- Blood and body fluids including respiratory secretions?
- Non-intact skin?
- Mucous membranes?
- Body tissues?
- Contaminated equipment?
3. How competent/experienced am I in performing this task?
4. Will the patient be cooperative while I perform the task?
Hand hygiene is the act of removing or destroying microorganisms on the hands while maintaining good hand integrity (keeping the skin healthy). Hand hygiene can be performed with an alcohol-based hand rub or with soap and water. You may refer to our OSH Answers document on hand washing for more information.
Personal Protective Equipment (PPE)
PPE includes gloves, gowns, lab coats, shoe covers, goggles, glasses with side shields, masks, and resuscitation bags. PPE is particularly needed when disease transmission may occur through touching, spraying, aerosolization, or splashing of blood, bodily fluids, mucous membranes, non-intact skin, body tissues, and contaminated equipment and surfaces. PPE can help create a barrier between the exposed worker and the source of microorganisms.
Gloves are for single-patient and single-procedure use only. Only disposable gloves should be used in the prevention of disease transmission. Gloves must be removed and replaced when they become heavily soiled and when working between patients and between dirty and clean tasks. Gloves should always be removed using a glove-to-glove or skin-to-skin technique which will prevent contaminating the hands.
The use of gloves does not replace the need for hand hygiene. Gloves often create a moist environment that facilitates the growth of microorganisms. Hands should be properly washed before the gloves are put on and after the gloves are removed. Hand hygiene is also needed before and after the replacement of gloves during a procedure or in between tasks.
Gowns can be either reusable or disposable. These steps of gown donning and removal should be followed:
- Perform hand hygiene.
- Put gown on, opening to the back.
- Fasten both the neck and waist ties.
- Unfasten ties and peel gown away from neck.
- Slip fingers of one hand under the wrist cuff and pull hand inside.
- With inside hand, push sleeve off with the other arm.
- Fold dirty-to-dirty and roll into bundle (do not shake).
- Discard in hamper.
- Perform hand hygiene.
Face protection can provide an effective barrier to protect a worker’s eyes, nose or mouth from coming into contact with sprays or aerosolized body fluids. There are different types and combinations of face protection, such as a mask with safety glasses, goggles, face shield (with safety glasses or goggles), or a mask with an attached visor (and safety glasses or goggles).
Steps to remove PPE
The proper steps when removing PPE are critical to prevent contamination of the worker with soiled PPE. The removal of PPE should be performed in the following order:
- Remove gloves.
- Remove gown.
- Perform hand hygiene.
- Remove eye protection.
- Remove mask.
- Perform hand hygiene.
Environmental control refers to controlling and minimizing the level of microorganisms in the environment. Environmental control measures include:
- Consistent and stringent equipment and work area cleaning, including laundry protocols and schedules.
- Proper disposal of waste such as sharps, biomedical, and pathological waste.
- Appropriate ventilation and other engineering controls.
- Installation of easily accessible and clearly identified waste containers, hand hygiene product dispensers, and dedicated hand wash sinks.
- Effective placement and segregation of sources of contamination - This control includes using single room and private toileting for patients who soil the environment, or using a "blood work only" biological cabinet for laboratory work associated with blood samples.
Administrative controls include employee training, supervisory competency, immunization, cough etiquette, workplace policies and procedures that are strictly enforced, and sufficient staffing. Administrative controls are critical to ensure that the principles of routine practices are effectively and properly executed in the workplace.
What are additional precautions?
In addition to routine practices, some workplaces apply additional precautions to prevent and control specific infectious agents. The methods of additional precautions are based on the mode of transmission -- contact, droplet, and airborne. Some microorganisms that require additional precautions include Methicillin-Resistant Staphylococcus Aureus (MRSA), Vanomycin-resistant enterococci (VRE) (included in drug-resistant organisms), Clostridium Difficile (C. difficile), Anthrax, Malaria, and West Nile virus.
Additional precautions include following routine practices, plus:
- Having specialized accommodation and appropriate signage.
- Using barrier equipment (specific PPE).
- Having dedicated equipment and additional cleaning measures.
- Limiting the transport of patients.
- Having good communication between departments or units.
Are routine practices required by law?
Occupational health and safety is regulated in Canada in each of the fourteen jurisdictions (provincial, territorial, and federal). Some jurisdictions may have also developed specific modifications of infection control guidelines. For more information on these, you may wish to contact the departments responsible for occupational health and safety and public health in your province.
