Study Notes
Infection Control and Safety
- Standard Precautions: Implemented to minimize infection transmission risks from both recognized and unrecognized sources in healthcare settings.
- CDC: The primary organization overseeing the investigation and control of communicable diseases in the U.S.
- OSHA: U.S. Department of Labor agency ensuring worker protection against biological hazards.
- Needlestick Protocol: Injured healthcare workers should contact their supervisor immediately after an accident and cleanse the area.
Nosocomial Infections
- Annual statistics indicate that approximately 1.75 to 3 million patients acquire nosocomial infections in the U.S.
- Common Pathogens: Escherichia coli is frequently identified as a causative agent in nursery units.
Isolation Procedures
- Reverse Isolation: Typically utilized for patients with immunodeficiency disorders to protect them from infections.
- Contact Precautions: Required for infections like scabies to prevent transmission.
- Airborne Precautions: Necessary for diseases such as measles and require specific room conditions, like negative air pressure.
Personal Protective Equipment (PPE)
- Correct sequence for PPE disposal after isolation: gloves, gown, mask.
- A respirator is classified as personal protective equipment necessary for certain airborne infections.
- Handwashing remains the most effective method for preventing disease transmission in healthcare settings.
Infection Chain Components
- Reservoir: Refers to a patient carrying the pathogen in the infection chain.
- Fomite: Inanimate objects, such as laboratory coats or doorknobs, that can harbor and transmit infectious agents.
- Pathogen: An infectious agent that needs to be present for nosocomial infections to occur.
Chemical Disinfectants and Antiseptics
- Disinfectants include chemicals like quaternary ammonium compounds, which kill pathogenic microorganisms.
- Antiseptics for skin care include iodine; they are essential for preparing areas for clinical procedures.
Specific Pathogens and Conditions
- Herpes Virus: Commonly identified pathogen affecting skin.
- MRSA: Methicillin-resistant Staphylococcus aureus; a significant hospital-acquired pathogen.
- Droplet Precautions: Used for conditions like diphtheria, with large-particle droplets larger than 5 microns.
Additional Key Concepts
- Infection control programs aim to break the chain of infection.
- Certain conditions, such as age and drug use, can increase a host's susceptibility to infections.
- A mite is an example of a vector that transmits infectious diseases.
