Study Notes
Transmission-Based Precautions Overview
- Used alongside Standard Precautions when dealing with documented or suspected infections from highly transmissible pathogens.
- Aim to further prevent transmission when Standard Precautions alone may not be sufficient.
Categories of Transmission-Based Precautions
-
Contact Precautions
- Necessary for infections spread through direct or indirect contact.
- Requires the use of gloves and gowns during patient interactions.
- Used for pathogens like MRSA or C. difficile.
-
Droplet Precautions
- Implemented for infections transmitted through respiratory droplets.
- Requires the use of masks when closer than six feet from the patient.
- Commonly applied for diseases such as influenza or COVID-19.
-
Airborne Precautions
- Essential for infections that can be transmitted via tiny aerosolized particles.
- Requires the use of specialized respiratory protection (e.g., N95 masks) and negative pressure environments.
- Important for pathogens like tuberculosis and chickenpox.
Importance of Transmission-Based Precautions
- Focus on interrupting specific routes of transmission linked to certain infectious diseases.
- Ensure the safety of healthcare workers, patients, and visitors in healthcare settings.
- Adaptation of precautions based on the nature of the pathogen and mode of transmission is critical for effective infection control.
