HAND HYGIENE
Overview
As an aide, you care for people in ways they need care - bathing, grooming, feeding and attending to all sorts of needs. This care involves close contact and touching, often with individuals who are ill, who have weak immune systems or who simply cannot afford to get sick.
You must recognize that you are a common factor between all your patients. This means that you can carry germs from one patient to another, even if you do not feel ill. Many illnesses such as the flu can be transmitted before symptoms develop. This means you must be on guard and use methods to prevent the spread of infection at all times. Once someone is sick, it's too late.
You don't have to use a hazmat suit all day long, but you should take simple yet effective measures every day. This in-service gives general and practical advice for stopping the spread of infection and explains effective measures to take and why they are so important.
Facts
Many people have weakened immune systems for a lot of different reasons, including cancer, HIV and receiving organ transplants. People who have undergone an operation have a higher chance of developing an infection. People with diabetes have a difficult time healing from skin infections and often suffer from unusually high blood sugar during illness. Older adults often cannot recover quickly from illness. Older people who come down with the flu or a chest infection might have a harder time staying hydrated and breathing. People who are susceptible to the flu can die from it. These are just a few examples of why it's critical to protect your patient population and yourself from getting ill.
Keeping a distance from those who are sick is a good prevention method but one that is difficult for health care workers to implement. Some illnesses, such as the flu, are spread through droplets in the air. Other illnesses are contracted only through bodily fluids. Many are spread by hands. Knowing and diligently applying the principles of hand hygiene and standard precautions is the best way of protecting your patients and yourself.
Hand Hygiene
Hand hygiene is the most effective way of preventing the spread of infection. Germs can stay on your hands and be transferred. Think of all the things and people you touch in a day. You use the bathroom, are in public spaces, handle money, care for patients, touch your face, touch doorknobs and food. The list is endless. Practicing good hand hygiene helps protect your patients, yourself, your family and others. You might think you don't always have time to clean your hands, but in all the things you're rushing around to do - caring for your patient - you might be causing more harm than good if you don't take a moment for hand hygiene.
KEY TERMS TO AID YOUR UNDERSTANDING
Hand hygiene:
A general term referring to any action of hand cleansing. This can include using an alcohol based hand sanitizer or soap and water.
Immune system:
A system of biological structures and processes within the body that protects against disease. A weakened immune system leaves the body susceptible to disease.
Contagious:
Able to be passed from one person or animal to another by touching.
You should use an alcohol-based hand rub or wash with soap and water; and wash your hands:
Immediately before touching a patient
Before performing task that involves handling medical devices such as catheters, drains, or other invasive devices
Before moving from work on a soiled body site to a clean body site on the same patient
After touching a patient or the patient's immediate environment
After contact with blood, body fluids, or contaminated surfaces including for procedures such as wound care
Immediately after glove removal
The Home Health Conditions of Participation (CoPs) specifically list six situations (at a minimum) in which hand hygiene should be performed in the home health setting:
Before contact with a patient
Before performing an aseptic task (insertion of IV, preparing an injection, performing wound care)
After contact with the patient or objects in the immediate vicinity of the patient
After contact with blood, body fluids or contaminated surfaces
Moving from a contaminated body site to a clean body site during patient care
After removal of personal protective equipment (PPE)
The CDC has guidelines for hand hygiene. They include:
Unless hands are visibly soiled, use an alcohol based hand-sanitizer rub to clean hands
When hands are visibly soiled, follow the following procedure for washing hands.
*Wet hands with warm water.
*Apply soap.
*Rub your hands palm to palm.
*Put one hand over the other, both palms facing down. Interlock your fingers and rub.
*Put your hands palm to palm, interlace your fingers and rub.
*With fingers together, grab one set of fingers with the other, palms facing each other.
*Grab your thumb with your other hand and twist; repeat with the opposite hand.
*With closed fingers, cup your hand and rub the tips of those fingers into the palm of your other hand. Do this to the opposite hand.
*Rinse hands.
*Dry hands thoroughly.
*Use a towel to turn off the faucet.
Always wash your hands when they are visibly soiled. Handwashing should take at least 15 seconds.
Current CDC hand-washing hygiene publications state 15 seconds for basic hand hygiene. Recent hand-washing guidance for COVID-19 states handwashing should take at least 20 seconds. Due to the ever-changing state of the pandemic, please check the CDC website for the most updated guidance.
Current CDC handwashing hygiene guidelines are found here:
Alcohol hand rub products are more effective than handwashing with soap unless the:
Hands are visibly soiled
Person has a condition that is known or potentially spread by spores, such as norovirus or Clostridium difficile diarrhea
Please note that the effectiveness applies only to alcohol-based products. Avoid sanitizers in which the active ingredient is triclosan or others that do not contain 60% to 95% alcohol. Higher concentrations of alcohol are more potent because they contain less water than lower concentrations. The increase in water in lower concentration sanitizers causes some of the original germ-killing properties to be lost or diminished.
The following are hand rub guidelines:
Apply the rub to your palm.
Rub hands together, palm to palm.
Put one hand over the other, both palms facing down. Interlock your fingers and rub.
Put your hands palm to palm, interlace your fingers and rub.
With fingers together, grab one set of fingers with the other, palms facing each other.
With closed fingers, cup your hand and rub it into the palm of your other hand. Do this to the opposite hand.
Continue to rub for length of time recommended by manufacturer, until hands are dry, or for at least 20 seconds. Hands must be dry for the sanitizer to be effective.
Clean personal equipment such as a stethoscope or bandage scissors with alcohol after use. Clean nonwashable items with disinfectant wipes.
Standard Precautions
Be familiar with the principles of standard precautions and select the correct personal protective equipment (PPE) for the task.
Guidelines for standard precautions
Routinely cleanse hands.
Wear gloves for any contact with blood, body fluids, secretions, excretions (except sweat), mucous membranes or nonintact skin. Also:
Anytime your hands are cut, scratched, chapped or have a rash
When cleaning up blood or body fluid spills
When cleaning potentially contaminated equipment
Make sure your gloves are intact and fit properly. Gloves that are torn or too large or small will not protect you.
Change gloves:
After caring for each patient
Before touching noncontaminated articles or environmental surfaces
Between tasks with the same patient if there is contact with infectious materials
When caring for multiple wounds on the same patient
Any time your gloves become soiled for any reason
Dispose of gloves properly, according to agency policy.
Wear a waterproof apron or gown for procedures that are likely to produce splashes of blood or other body fluids:
Remove a soiled apron or gown as soon as possible and dispose of it properly.
Wash your hands.
Wear a mask and protective eyewear or a face shield for procedures that are likely to produce splashes of blood or other moist body fluids. The surgical mask covers both the nose and the mouth.
The mask is used once and discarded. If it becomes damp during use, change it. Masks lose their effectiveness when moist.
Goggles or a face shield help protect the mucous membranes of the eyes from splashes or sprays of blood and other body fluids. Wear a surgical mask with goggles or a face shield to protect the nose and mouth. Your eyeglasses, if you wear them, will not protect you.
A good rule to follow is that a surgical mask may be worn without protective eyewear, but protective eyewear is never worn without a surgical mask. Apply the mask first, followed by the protective eyewear. Some one-piece, disposable masks have a protective eye shield attached to them.
You should:
Know where to obtain PPE.
Correctly apply the PPE.
Be familiar with the principles of standard precautions and select the correct PPE for the task.
Do not contaminate environmental surfaces with used PPE. Correctly remove and discard the PPE before leaving the work area. Place used PPE in the proper container for laundering, decontamination or disposal. A plastic bag is usually the best option.
Remember that humans need to be touched. It is not necessary to wear gloves 100% of the time unless needed to apply the principles of standard precautions.
Wear Gloves
Gloves are an important part of patient care. They are worn to avoid:
Picking up a pathogen from a patient
Giving a patient a pathogen that is on your hands
Picking up a pathogen and contaminating environmental surfaces and personal property on the hands
Passing a pathogen to a coworker, visitor, family member (or other person) from your hands
Clean exam gloves are generally used in the home. Most of the gloves used today are made of nitrile, vinyl and other synthetic products. Inform your employer if you are allergic to latex. They will provide another type of glove. Disposable gloves are to be used only once and may not be washed for reuse. Even if he or she is properly gloved, an aide who has broken skin should be sure to inform the care team members. Gloves do not take the place of proper hand hygiene. You must clean your hands before and after touching a patient, even if you wear gloves.
Gloves will become contaminated while providing care to a patient, so it's important to remove gloves immediately after providing that care. Gloves must be changed if they become damaged or soiled in any way. It's easy to contaminate the patient's room with gloved hands, so aides must remove gloves, wash hands and replace gloves in the presence of open sores and cuts, before touching bodily fluids, and before and after:
Assisting with or performing mouth care
Assisting with or performing perineal care
Performing any other personal care
Shaving a patient
Disposing of soiled linens, dressings or pads
Putting on gloves:
Wash hands
Place glove on one hand
With your gloved hand, put the other glove on
Look for tears and holes and immediately replace gloves that are damaged
Taking off gloves:
Touching the outside of one glove with the gloved fingers of the other hand, pull the glove down from the wrist.
As the glove comes off, roll it inside out.
Hold the removed glove in your opposite gloved hand.
With bare fingers, grasp the inside of your glove and roll it down from the wrist, turning it inside out. You will now have one glove in your hand, clean side out, with the other glove inside it.
Dispose of used gloves properly.
Wash hands again.
Sick Days
If you feel sick, you might think that your patients still need you and the gallant thing to do is to work anyway. However, you should assess how sick you are and take the necessary precautions. Discuss with your supervisor whether you should work at all that day.
Vaccination
Health care workers should be vaccinated against many diseases including the flu and COVID-19. Because you provide care in close quarters with many patients, your having the flu creates a danger to a wider net of people who are more vulnerable to illness. Every health care worker who doesn't come down with the flu or COVID-19 could stop countless others from catching these highly contagious viral conditions.
Sanitation
Always wipe down and clean high-traffic areas or hazardous areas, such as surfaces in bathrooms and kitchens. Wipe items that are used for meals or snacks, such as tray tables or trays attached to wheelchairs, with soap and water after each use. Keep kitchen eating and food preparation surfaces clean. Wiping down doorknobs, cabinet knobs, counters, remote controls, phone receivers, cell phones, toilet flush handles, faucets, keyboard, mouse, light switches and handles to appliances such as the microwave, oven or toaster often is always a good idea. Linens, eating utensils and dishes belonging to those who are sick should not be shared without washing thoroughly first.
Sneezing and Coughing
Never sneeze or cough into your hands. If you do accidentally, be sure to immediately sanitize or wash them. Using a tissue is best, but if you can't use a tissue, use the crook of your arm. This is an area unlikely to touch others and it provides a better shield to prevent contact with others. Either way, clean the hands or elbow with alcohol. Discard tissues correctly. Try to cough and sneeze away from others. Even if the cause is allergies, you can still transmit microbes you might be carrying.
General Infection Control Practices
To limit the spread of infection, follow your agency infection control procedures. Some tips to remember include:
Basic handwashing: Wash your hands before and after patient care. Use an alcohol-based hand sanitizer if your hands are not visibly dirty.
Use warm water and soap when washing hands. Hot water from the tap is not hot enough to kill germs and can cause skin problems.
Cough or sneeze into a tissue and then discard the tissue. Clean your hands with alcohol. If you do not have a tissue, cough into your elbow or upper sleeve.
Wash your hands with soap and water after coming in contact with any body fluids from your patient or yourself. This includes an unprotected sneeze or cough.
Wear gloves for patient care that may include body fluids.
Wear a surgical mask for care of patients with flu.
Try not to touch your face. Germs from your hands can enter the mouth, nose or eyes through contact.
Do not share drinks or food.
Use gloves when emptying wastebaskets at the patient's home to avoid contamination by used tissues and other items carrying germs.
Use gloves when cleaning the patient's home to avoid contact with germs on the surface of chairs, tables, toilets, wheelchairs and other items. Remember that germs can travel many feet from a sneeze.
Patient Education
Stopping the spread of illness is everyone's job. Teach your patient to use alcohol hand cleaner or wash hands often and to keep a clean home. Make sure the patients tell you when they're not feeling well. Teach them this content. Be sure they keep surfaces clean and keep liquid soap in the bathroom.
Outcomes and the aide
Infection control prevents harm to the patient and others. The last thing a patient needs is to develop an infection. Viruses like the flu can make recuperation difficult and take longer. A recently discharged patient may have to return to the hospital. Old, young, chronically ill and healthy people die of the flu each year.
Your role in preventing these outcomes is critical. As a constant observer, you can also alert the health care team if a patient has signs of infection so treatment can begin as soon as possible.
CMS' Expectations
As a result of the Outcome and Assessment Information Set (OASIS), the Centers for Medicare & Medicaid Services (CMS) reviews the quality outcomes and processes regarding the care an agency provides. It also reviews potentially avoidable events. It expects that agencies use the information available for their quality improvement programs. CMS expects an agency's quality improvement efforts to take a multidisciplinary approach in meeting and improving the care needs of its patients.
