There are things that all AHS staff can do to prevent infection, resulting in a healthier workplace for staff, patients, residents and clients. Infection Prevention and Control is important at any time, but particularly so during infectious outbreaks such as the 2009 H1N1 influenza pandemic. _______________________________________________________________________ Objectives By the end of this module, you will be able to: List and describe the elements of Routine Practices. List four requirements for an infection to spread. List six ways a microorganism can get into the body. List three ways that a microorganism can leave the body. Demonstrate the correct methods for performing hand hygiene. Demonstrate proper respiratory hygiene. Describe four kinds of Personal Protective Equipment (PPE) Describe how to maintain a healthy workplace. Describe what to do if you are sick. _______________________________________________________________________ Routine Practices Routine Practices are things you can do to reduce your exposure to disease-causing microorganisms. Understanding Routine Practices involves understanding the following things: 1. The process of disease transmission 2. Hand hygiene 3. Respiratory hygiene 4. Proper use of Protective Personal Equipment (PPE) 5. Handling sharps safely (such as needles, scalpels, etc.) 6. Keeping client care equipment clean 7. Keeping your work environment clean 8. Proper laundry procedures 9. Proper waste management and disposal 10. Careful client placement (or patient accommodation) 3 1. The Process of Disease Transmission (Or, How To Become Infected) There are four things needed to transmit an infection: An infectious agent A source for the infection A way for the microorganism to spread A way for the microorganism to enter a person who is at risk for getting sick (susceptible host) An infectious agent: This is any disease-causing microorganism, such as a virus or bacterium. A source for the infection: People normally come in contact with viruses and bacteria and can pass these microorganisms to another person. Sources include food, water, insects, animals, objects, and other people. A way for the microorganism to spread: There are three main ways that a microorganism can get into a person to make them sick. These are: Contact transmission: This includes direct and indirect contact. • Direct contact: Occurs when microorganisms are transferred from direct physical contact or body surface to body surface contact between an infected person and a susceptible person. • Indirect contact: Occurs when microorganisms are transferred to a susceptible person on an intermediate object such as contaminated equipment, instruments or objects in the environment. Droplet transmission: This is a type of indirect contact and happens when someone talks, coughs, or sneezes, creating large droplets that are propelled up to 2 metres through the air. The droplets can land on environmental surfaces, or in the mouth, nose or eyes of a susceptible person. Airborne transmission: This type of infection transmission occurs when microorganisms are contained in small droplets or in dust particles that remain suspended in the air for long periods of time. These particles can be inhaled or deposited a long distance away from the infected person. A person who is at risk for getting an infection (Susceptible Host): Not everyone will get sick if they come in contact with a disease-causing microorganism and, if they do, some people will get sicker than others. Everyone has natural defenses against diseasecausing microorganisms, but some people will have poor defenses because they are very young or very old, they have another illness, their natural immune systems aren’t working well, or they are experiencing a lot of stress. 4 Disease-causing microorganisms can get into your body when you: consume food or drinks contaminated with the microorganism touch your eyes, nose, or mouth have an open cut or sore on your skin breathe it in are exposed to an infected animal or insect or have contact with contaminated solutions, needles, syringes, or other medical devices. Disease-causing microorganisms can leave your body in: secretions or droplets that are released when you cough or sneeze blood or other body fluids such as diarrhea, vomit or drainage from a sore or wound or the air that you breathe out 2. Hand Hygiene This is the single most important thing you can do to prevent spreading disease-causing microorganisms, and fortunately it’s also the easiest! It is important to perform hand hygiene at the following times: before contact with a patient or patient’s environment. This includes but is not limited to: • putting on (donning) Personal Protective Equipment (PPE)*; • entering a patient’s room; and • providing patient care, before a clean or aseptic procedure. This includes but is not limited to: • wound care; • handling intravenous devices; • handling food or • preparing medications, after exposure (or risk of exposure) to blood and/or body fluids. This includes but is not limited to: • when hands are visibly soiled; • following removal of gloves 5 after contact with a patient or patient’s environment. This includes but is not limited to: removing (doffing) PPE; • leaving a patient’s environment; and • after handling patient care equipment. *Make sure you clean your hands before removing gloves from the box in which they are stored. If you do not, your unclean hands will contaminate the entire box of gloves. How do you perform hand hygiene? You can do this in two ways: use an alcohol-based hand rub, or use soap and water. When your hands look clean, use an alcohol-based hand rub. The hand rub should have between 60 and 90% concentration of ethyl or isopropyl alcohol. Here’s how: ensure that your hands are not visibly soiled and are dry before use; apply enough product to the palm of one hand to cover all hand surfaces (e.g. 2 to 3 pumps); vigorously rub product over all the surfaces of the hands and wrists, including: palms, spaces between fingers, back of hands and wrists, fingers, fingertips and thumbs; your hands must remain wet with the product for a minimum of 15 seconds; continue rubbing product over hands until hands are completely dry; and periodically apply Alberta Health Services approved hand lotion to assist in maintaining skin integrity. When you can see soil on your hands, wash them using soap and water. Here’s how: make sure the sink you are using is for hand hygiene and not for other purposes such as cleaning soiled equipment or discarding body fluids or specimens; wet hands with warm water, apply enough soap to ensure all hand surfaces are lathered thoroughly (e.g. 2 to 3 pumps); vigorously rub soap product over all the surfaces of the hands and wrists, including: palms, spaces between fingers, back of hands and wrists, fingers, fingertips and thumbs for a minimum of 15 seconds; rinse hands under warm running water; pat hands dry with disposable paper towels; use paper towels to turn off faucets and to open door; discard towels; and 6 periodically apply an Alberta Health Services approved hand lotion to assist in maintaining skin integrity. Fingernails, Hand Jewelry and Ability to Perform Hand Hygiene: If you provide direct patient care or if you reprocess medical devices or surgical linens, prepare pharmaceuticals or medications or handle food: artificial nails, nail enhancements (including gel and acrylic nails), or chipped nail polish must not be worn, your fingernails should be natural and short, and rings worn on your hands should be limited to plain bands. If you work or provide service in one of the above areas and must wear casts, splints or dressings that interfere with proper hand hygiene, contact your manager or supervisor. They will contact Workplace Health and Safety for direction. 3. Respiratory Hygiene Respiratory hygiene includes covering your mouth and nose when you cough or sneeze, and performing hand hygiene afterward. The best way to do this is to cough or sneeze into your upper arm or sleeve, or into a tissue. If using a tissue, dispose of the tissue right away. Do not save or reuse the tissue; perform hand hygiene. 4. Proper Use of Protective Personal Equipment (PPE) PPE protects you from blood and body fluids and disease-causing microorganisms by putting an extra barrier in front of clothing, skin and mucous membranes. The most common PPE worn by healthcare workers are: Gloves: Vinyl, latex, or nitrile disposable gloves protect hands from exposure to body fluids, blood, or chemicals. You’ll wear gloves when there is any risk of touching or being splashed by these hazards. For example, when changing a dressing or diaper, cleaning up an incontinent client, inserting an IV, obtaining blood specimens or performing mouth care you should wear gloves. Don’t use gloves when feeding a client, touching somebody in a social manner, pushing a wheelchair, delivering meals, mail or clean supplies, or providing care to clients with intact skin. Gowns: Gowns protect your exposed skin and clothing from splashes, sprays, or soiling during procedures and client care activities. 7 Masks and facial protection. Wearing eye protection and surgical/procedure masks or full face shields protects mucous membranes of your eyes, nose, and mouth from splashes and sprays of blood, body fluids, and respiratory secretions. They should be worn when you are within 2 metres of a patient with respiratory illness and /or when performing or assisting with a medical procedure that may produce splashes. N95 Respirators: These masks are filters that fit the face tightly in order to prevent breathing in airborne microorganisms such as TB. They should also be worn when performing or assisting with procedures such as sputum inductions that create small droplet aerosols. You must be fit tested for these masks and be aware of your correct size before using them. If you are required to use any of this equipment, please visit the AHS Infection Prevention and Control website or speak to your manager. 5. Handling Sharps Safely Sharps are contaminated medical devices that can pierce the skin. They most often include needles, scalpels, and sutures. There are specific ways to handle, clean, and dispose of used sharps. All needles must be disposed of in an approved sharps container immediately after use and must not be recapped or left at the patient’s bedside or point of care. Make sure you do not fill any sharps container more than three quarters full or past the fill line. If your job involves the use or handling of sharps, you will learn how at your worksite. 6. Keeping Client Care Equipment Clean Any item that is labeled single use must not be reused. If a piece of medical equipment is for multi-use, ensure that it is cleaned and disinfected or sterilized, as appropriate, following use, each and every time. 7. Keeping Your Work Environment Clean If you are responsible for cleaning environmental surfaces such as bedside tables or medication preparation areas, be sure that the surface is free of visible soil prior to disinfecting. This requires a two-step procedure: first, remove soil with a wipe or cloth moistened with cleaning solution; then, with a clean, disinfectant moistened wipe or cloth, re-clean the surface. Make sure that the disinfectant solution has wet contact with the surface for the time recommended on the product label. 8 8. Proper Laundry Procedures When disposing of contaminated linen, ensure that laundry bags or receptacles are only filled three quarters full and not overfilled. Do not double bag unless there is leakage or the bag is torn. 9. Proper Waste Management and Disposal Make sure that waste is handled and disposed of properly according to its category: general, biomedical, and pathological waste. Do not overfill waste containers. Please see the Waste Management Sheet on page 12 for details. 10. Careful Client Placement This involves arranging clients or patients in such a way as to minimize risk of transmission. Patients with known communicable diseases or symptoms of communicable diseases should not be placed near other at-risk patients. _______________________________________________________________________ Safe Injection Practices If you use needles or needleless cannulas to provide injections to patients, it’s vital to remember: New Needle, New Syringe, Every Time! NEVER administer medications from the same needle/cannula or syringe to more than one patient. A new needle/cannula and a new syringe must be used for each entry into a medication vial Using a new alcohol or chlorhexidine gluconate (CHG) swab: • Clean* the stoppers of all medication and solution vials prior to each entry with a needle. • Clean* all injection ports of medications, solutions, and delivery systems prior to each entry. *Cleaning requires vigorous rubbing for a minimum of 15 seconds with an alcohol or CHG swab. Remember to “Scrub the hub”. 9 _______________________________________________________________________ Risk Assessment This involves finding out symptoms of illness or other risk factors as early as possible. Based on this information, it is important to place clients safely, wear PPE, perform hand hygiene, and manage equipment in a way to prevent disease transmission. If a patient has a known illness or disease-causing microorganism, contact Infection Prevention and Control to see if any additional precautions are required. _______________________________________________________________________ Maintaining a Healthy Workplace This includes making sure that you: stay home if you have an infection or if you have been exposed to a communicable disease that you could spread to others, have all your immunizations up to date. This includes, but is not limited to annual influenza immunizations, protect and cover broken skin, contact Workplace Health and Safety as soon as possible if you suspect that you have been exposed to blood and body fluids, have received a needle stick injury, or are injured at work, clean your hands frequently and contact Workplace Health and Safety if you must wear a splint, cast or dressing that interferes with proper hand hygiene. This applies if you work in an area where you provide direct patient care or reprocess medical devices or surgical linens, prepare pharmaceuticals or medications or handle food. _______________________________________________________________________ What if I’m sick? Should I still go to work? If you have a cold, influenza or diarrhea, or if you have been exposed to a disease or condition that can be easily passed on to others, it’s best not to come to work until you are better or no longer communicable. Check with your supervisor by phone and describe your situation if you’re not sure. Don’t be “tough” and show up to work when you shouldn’t. If you do, clients, patients, and co-workers may become sick too. 10 _______________________________________________________________________ Education Learning about Routine Infection Control Practices ensures that you know how to protect yourself from being exposed to unnecessary risk. Knowing how to perform hand hygiene and cover your cough, complete risk assessments, and use PPE correctly are key elements in preventing the spread of infection.
