CVTE 113 Exam #1 Infection control and hospital safety Flashcards
NOSOCOMIAL INFECTION— Scope of problem:
In 1974, What percent of staph infections were antibiotic resistant? Today?
In 1974, 2% of staph infections were resistant to antibiotics.
Today, more than 60% are.
PREVENTION OF
Spread of infection
Exposure to hazardous substances
Accidents
Injury to yourself (especially your back)
How many people does MRSA infect annually in the USA?
How many does it kill?
How many infections are linked to health care facilities?
MRSA infects nearly 95,000 annually in the USA,
and kills more than 18,500.
85% of MRSA infections are linked to health care facilities.
Line infections:
How many lines are in the ICU each year?
How many get infected after 10 days? per year?
What percent are fatal?
How many have serious complications of some kind?
5 million lines in ICU each year
After 10 days, 4% get infected: 80,000 per year
5–28% of these are fatal
About 1⁄2 have serious complications of some kind
Hand-washing:
Washing your hands controls infection by what percent?
What is a nosocomial infection?
When to wash your hands, how long, how many inches above your wrist?
99% of the battle in controlling infection.
Nosocomial infection: caused by transfer of bugs in hospital.
Wash before and after each patient contact. 15 to 20-second wash is recommended, with plenty of soap and friction.
Go 3 inches above wrist.
When is hand sanitizer okay?
Hand sanitizer is okay for routine patient contact, but you should wash hands periodically as well.
(Sanitizer may be replacing the surgical scrub? We’ll see.)
What percent of men and women wash their hands after using public restrooms?
How many health care workers regularly wash their hands while on the job?
Physicians ties?
12% of women and 34% of men do not wash hands after using public restrooms.
Fewer than 50% of health care workers regularly wash their hands while on the job. A sampling of doctors’ ties found staph on 1/3 of them.
Protective attire (PPE):
Gloves (many recommend for all patient contact)
Gown
Mask (especially for TB, other airborne diseases)
Goggles, to prevent fluids getting into eyes Look for isolation cart, sign on door, etc.
Sharps:
recap safety?
where do you dispose of needles?
what do you do if you stuck yourself?
Be very careful with needles, scalpels, etc.
Never recap used needles— too easy to miss and stick yourself.
Use sharp disposal box (careful with that too…)
If you stick yourself, or even think you might have stuck yourself, report it immediately.
What are Standard Precautions?
What is UP?
what is BSI?
Combine the major features of Universal Precautions (UP) and
Body Substance Isolation (BSI) Based on the principle that all blood, body fluids, secretions, excretions except sweat, nonintact skin, and mucous membranes may contain transmissible infectious agents.
Who should you consider to be potentially infectious?
“Consider all personnel (patients and staff) as being potentially infectious.”
Body fluids that can transmit disease:
Blood Urine, Feces Semen, Vaginal secretions, Breast milk Saliva Spinal fluid, Joint fluid
When to Perform hand hygiene:
- Before having direct contact with patients.
- After contact with blood, body fluids or excretions, mucous membranes, nonintact skin, or wound dressings.
- After contact with a patient’s intact skin (e.g., when taking a pulse or blood pressure or lifting a patient).
When to perform hand hygiene continued:
- If hands will be moving from a contaminated-body site to a clean-body site during patient care.
- After contact with inanimate objects (including medical equipment) in the immediate vicinity of the patient .
- After removing gloves.
Wear gloves when it can be reasonably anticipated that:
contact with blood or other potentially infectious materials,
mucous membranes, nonintact skin,
or potentially contaminated intact skin (e.g., of a patient incontinent of stool or urine) could occur.
When to wear Masks, goggles, face masks:
Protect mucous membranes of eyes, nose, and mouth when contact with blood and body fluids is likely.
Summary of standard precautions:
Standard Precautions include the use of one or combinations of the following practices. The level of use will always depend on the anticipated contact with the patient.
-Handwashing, the most important infection control method
-Use of latex, nitrile, or other protective gloves (must be aware of possible latex allergy)
-Masks, eye protection, and/or face shield
-Gowns
Proper handling of soiled patient care equipment
-Proper environmental cleaning
-Minimal handling of soiled linen
-Proper disposal of needles and other sharp equipment such as scalpels
-Placement in a private room for patients who cannot maintain appropriate cleanliness or contain body fluids.
Respiratory Hygiene (Cough Etiquette): Measures to avoid spread of respiratory secretions should be promoted to help prevent respiratory disease transmission.
Elements of respiratory hygiene and cough etiquette include:
Covering the nose/mouth with a tissue when coughing or sneezing or using the crook of the elbow to contain respiratory droplets.
Using tissues to contain respiratory secretions and discarding in the nearest waste receptacle after use.
Respiratory Hygiene (Cough Etiquette): Performing hand hygiene:
hand washing with non-antimicrobial soap and water, alcohol-based hand rub, or antiseptic hand wash
immediately after contact with respiratory secretions and contaminated objects/materials.
Provide tissues and no-touch receptacles for used tissue disposal.
Respiratory Hygiene (Cough Etiquette): in waiting rooms: Supplies such as tissues, waste baskets, alcohol gel, and surgical masks should be provided in waiting and other common areas in local public health agencies. Place cough etiquette signs where the general public can see them.
- Asking clients with signs and symptoms of respiratory illness to wear a surgical mask while waiting common areas or placing them immediately in examination rooms or areas away from others.
- Spacing seating in waiting areas at least three feet apart to minimize close contact among persons in those areas.
