Copyright © 2008 Delmar Learning. All rights reserved. Disease Prevention In the last unit, you learned what infections are and some of their causes In this unit –You will learn actions and procedures that can help prevent the transmission of infection to protect yourself, your coworkers, and those in your care

Copyright © 2008 Delmar Learning. All rights reserved. Medical Asepsis Asepsis –Absence of disease-producing microorganisms

Copyright © 2008 Delmar Learning. All rights reserved. Medical Asepsis Medical asepsis –Reducing the numbers of disease- producing microorganisms –Or interrupting transmission from one person to another person or from a person to a place or an object

Copyright © 2008 Delmar Learning. All rights reserved. Handwashing Single most important health procedure any individual can perform to prevent the spread of microbes

Copyright © 2008 Delmar Learning. All rights reserved. Handwashing Vigorous, short rubbing together of all the surfaces of soap-lathered hands Followed by rinsing under a stream of running warm water Handwashing should take at least 15 seconds

Copyright © 2008 Delmar Learning. All rights reserved. Waterless Hand Cleaners Many facilities provide dispensers containing waterless hand cleaners in various locations

Copyright © 2008 Delmar Learning. All rights reserved. Waterless Hand Cleaners Hand cleaners –Alcohol-based gel, lotion, or foam that is dispensed in small dime- to quarter-sized portions –Alcohol products may be used to clean your hands for most routine care

Copyright © 2008 Delmar Learning. All rights reserved. Using Alcohol Hand Cleaner Wash at the sink if: –Hands are soiled with a protein substance –Patient is known or suspected of having a disease caused by spores

Copyright © 2008 Delmar Learning. All rights reserved. Hand Lotion and Cream Maintaining the integrity of the skin on your hands –Very important to prevent injury and exposure to microbes

Copyright © 2008 Delmar Learning. All rights reserved. Hand Lotion and Cream Hand care products –Use products from individual, personal size packages, or from a pump dispenser or squeeze bottle, but don’t touch the spout –Avoid products in a jar

Copyright © 2008 Delmar Learning. All rights reserved. Protecting Yourself As you perform your duties, you may contact potentially infectious material –Blood or other body fluids, that may contain pathogens

Copyright © 2008 Delmar Learning. All rights reserved. Standard Precautions Infection control actions used for all people receiving care –Regardless of their condition or diagnosis

Copyright © 2008 Delmar Learning. All rights reserved. Standard Precautions Previously called Universal Precautions Assumes blood and body fluid of any patient could be infectious

Copyright © 2008 Delmar Learning. All rights reserved. Standard Precautions Recommends PPE and other infection control practices to prevent transmission in any healthcare setting Decisions about PPE use determined by type of clinical interaction with patient

Copyright © 2008 Delmar Learning. All rights reserved. PPE for Standard Precautions (1) Gloves –Use when touching blood, body fluids, secretions, excretions, contaminated items –For touching mucus membranes and nonintact skin

Copyright © 2008 Delmar Learning. All rights reserved. PPE for Standard Precautions (1) Gowns –Use when in contact with clothing, exposed skin with blood/body fluids, secretions, or excretions

Copyright © 2008 Delmar Learning. All rights reserved. PPE for Standard Precautions (2) Mask and goggles or a face shield –Used during patient care activities likely to generate splashes or sprays of blood, body fluids, secretions, or excretions

Copyright © 2008 Delmar Learning. All rights reserved. Transmission-Based Precautions Standard precautions do not eliminate the need for other isolation precautions A second set of precautions is used with certain highly transmissible diseases Second tier of precautions is called transmission-based precautions

Copyright © 2008 Delmar Learning. All rights reserved. Four Isolation Techniques 1.Isolation technique is the name given to the method of caring for patients with easily transmitted diseases 2.Essential that every person take responsibility and use the proper isolation techniques to prevent the spread of disease to others

Copyright © 2008 Delmar Learning. All rights reserved. Four Isolation Techniques 3. All items that come into contact with a patient’s excretions, secretions, blood, body fluids, mucous membranes, or nonintact skin are considered contaminated. Infectious material must be treated in a special way.

Copyright © 2008 Delmar Learning. All rights reserved. Isolation Technique 4. Standard precautions are always used in addition to transmission-based precautions

Copyright © 2008 Delmar Learning. All rights reserved. Isolation Unit May be an area or a private room Patients with the same disease may share a room A room with handwashing facilities and an adjoining room with bathing and toilet facilities is best

Copyright © 2008 Delmar Learning. All rights reserved. AII (A2) Rooms Rooms with a special air handling system may be called A2 rooms These rooms have negative pressure –Air flow in which air from the room is vented directly to the outside –Or filtered so pathogens cannot escape

Copyright © 2008 Delmar Learning. All rights reserved. AII (A2) Rooms Ventilation is needed for airborne precautions A HEPA respirator or NIOSH-approved mask –Must always be worn when entering an airborne precautions room

Copyright © 2008 Delmar Learning. All rights reserved. Ultraviolet Germicidal Irradiation (UVGI) Ultraviolet Germicidal Irradiation (UVGI) lights –Used to eliminate pathogens in some isolation rooms

Copyright © 2008 Delmar Learning. All rights reserved. Ultraviolet Germicidal Irradiation (UVGI) UVGI lights –Used intermittently as a secondary measure to kill or inactivate the pathogens in the upper portion of the room or passing through the air duct

Copyright © 2008 Delmar Learning. All rights reserved. Ultraviolet Germicidal Irradiation (UVGI) Lights are not on all the time Not a threat to the patient or health care workers

Copyright © 2008 Delmar Learning. All rights reserved. The Anteroom Used to enter some isolation rooms Is a small room inside the entrance to the patient room It contains a sink and containers for trash disposal

Copyright © 2008 Delmar Learning. All rights reserved. The Anteroom Reduces escape of infectious organisms when the door is opened and closed It serves as a buffer between the changes in air pressure in the patient room and the hallway Refer to Figure 13-11

Copyright © 2008 Delmar Learning. All rights reserved. The Anteroom

Copyright © 2008 Delmar Learning. All rights reserved. Additional Respiratory Precautions CDC recommends: –Teaching new admissions and those who accompany them to use respiratory precautions –Notifying staff if symptoms of a respiratory infection are present when they first register for care
