Study Notes
Introduction to Asepsis and Infection Control
- Asepsis refers to the absence of pathogenic microorganisms.
- It's crucial in preventing infections, protecting patients and healthcare providers.
- Infection control focuses on preventing transmission of microorganisms.
- Hand hygiene is a cornerstone of both asepsis and infection control.
Types of Asepsis
- Medical asepsis: reducing the number of pathogenic microorganisms.
- Techniques include hand hygiene, proper handling of equipment, and environmental cleaning.
- Surgical asepsis: eliminating all microorganisms.
- Critical for invasive procedures, aiming for a sterile field.
- Includes meticulous handwashing, gowning, gloving, and maintaining sterile technique.
Chain of Infection
- Factors needed for infection to occur:
- Infectious agent (bacteria, viruses, fungi).
- Reservoir (where organisms live; humans, water, food, animals).
- Portal of exit (way organisms leave the reservoir).
- Mode of transmission (how organisms move: direct contact, airborne droplets).
- Portal of entry (way organisms enter a new host).
- Susceptible host (host's ability to fight off the infection).
Modes of Transmission
- Direct contact: physical touch (e.g., shaking hands).
- Indirect contact: contact with contaminated objects (e.g., needles).
- Droplet transmission: large droplets expelled during coughing or sneezing (within ~3 feet).
- Airborne transmission: microorganisms travel via air currents (e.g., tuberculosis).
Factors Affecting Susceptibility to Infection
- Age (very young and very old are more vulnerable).
- Nutritional status (poor nutrition weakens immune response).
- Stress levels (stress compromises immune function).
- Chronic illness (diabetes, HIV weakens immune system).
- Medications (immunosuppressants).
- Immune deficiencies (conditions affecting immune system).
- Surgery, wounds, and invasive procedures.
Standard Precautions
- Applying precautions to all patients regardless of suspected infection.
- Includes hand hygiene, use of personal protective equipment (PPE), sharps disposal, and respiratory hygiene.
Transmission-Based Precautions
- Additional precautions based on a known or suspected infection.
- Contact precautions: used for infections spread via contact.
- Examples: gowns, gloves, and hand hygiene.
- Droplet precautions: used for infections spread via droplets.
- Examples: masks and hand hygiene.
- Airborne precautions: used for infections spread via airborne particles.
- Examples: N95 respirator masks and hand hygiene.
- Protective environment precautions: used for very vulnerable patients with compromised immune systems.
Hand Hygiene
- Crucial for preventing infection transmission.
- Proper handwashing technique: using soap and water or alcohol-based hand sanitizer.
- Focus on handwashing before and after patient care, after contact with body fluids.
- Types of hand hygiene methods
- Handwashing with water and soap
- Handwashing with antiseptic agents
- Antiseptic hand rub
Personal Protective Equipment (PPE)
- Using appropriate PPE to prevent transmission of infections.
- Different PPE for each type of precautions.
- Examples: gloves, gowns, masks, eye protection.
- Proper donning and doffing of PPE to avoid contamination.
Waste Disposal
- Proper disposal of sharp objects, contaminated materials, and other waste.
- Red bag/container for biohazardous/infectious waste.
- Proper disposal procedures vary by location.
Environmental Considerations
- Maintaining a clean and sanitary environment.
- Regular cleaning and disinfection of surfaces and equipment to minimize transmission risk.
Infection Prevention and Control Programs
- Implementing effective infection control policies within a healthcare setting.
- Regular training on infection control protocols for healthcare providers.
- Surveillance systems to monitor infection rates.
Emerging Infectious Diseases
- Awareness of new or re-emerging infectious diseases and the potential for infection is important.
