Module 6: Infection Control and Prevention

Core Concepts of Infection Control in Caregiving

1. Definition of Infection Control:

   • Infection control involves measures taken to prevent the spread of infections in healthcare settings and during caregiving activities.

2. Importance of Infection Control:

   • Infection control is crucial in protecting both clients and caregivers from contagious diseases. It helps prevent the spread of harmful microorganisms, such as bacteria, viruses, and fungi.

Key Infection Control Practices

1. Hand Hygiene:

   • Handwashing is the most effective way to prevent the spread of infections. Caregivers should wash their hands with soap and water for at least 20 seconds before and after providing care, after using the bathroom, and before handling food.

   • Hand sanitizers can be used when soap and water are not available, but they should contain at least 60% alcohol to be effective.

2. Use of Personal Protective Equipment (PPE):

   • PPE includes gloves, masks, gowns, and face shields, which help protect both the caregiver and the client from infection.

   • Caregivers must use appropriate PPE when there is a risk of exposure to bodily fluids or infectious agents.

3. Proper Handling and Disposal of Contaminated Items:

   • Caregivers must properly dispose of contaminated items such as used gloves, bandages, and soiled linens in designated biohazard containers.

4. Cleaning and Disinfecting:

   • Surfaces and equipment used in caregiving should be regularly cleaned and disinfected to reduce the risk of infection.

Types of Infections

1. Healthcare-Associated Infections (HAIs):

   • Infections that occur during the course of receiving medical care, such as urinary tract infections (UTIs), respiratory infections, or wound infections.

2. Bloodborne Pathogens:

   • Bloodborne pathogens are infectious microorganisms in blood that can cause diseases, such as hepatitis B, hepatitis C, and HIV. Caregivers must take precautions to avoid exposure, such as using PPE and safely disposing of sharps (needles, lancets).

3. Airborne and Droplet Infections:

   • Infections like the flu, tuberculosis, or COVID-19 can spread through airborne droplets. Masks and proper ventilation are important for preventing the spread of these infections.

Precautions and Procedures

1. Standard Precautions:

   • Standard precautions are infection control practices that should be used with every client, regardless of whether they have a known infection. These include hand hygiene, using PPE, and safely handling waste.

2. Transmission-Based Precautions:

   • Transmission-based precautions are additional measures used when dealing with known or suspected infections that spread via contact, droplets, or airborne transmission.

3. Isolation Procedures:

   • In cases of highly contagious diseases, isolation procedures are used to keep infected clients separate from others to prevent the spread of infection.

Steps to Prevent Infection Spread

1. Regular Handwashing:

   • Wash hands before and after client contact, after using the restroom, and after touching any potentially contaminated surfaces.

2. Correct Use of PPE:

   • Always wear gloves when handling bodily fluids, and wear masks when caring for clients with respiratory infections.

3. Safe Disposal:

   • Dispose of contaminated items, such as used gloves and sharps, in biohazard containers.

4. Disinfection of Surfaces:

   • Regularly disinfect high-touch surfaces like door handles, equipment, and client care areas.
