Study Notes
Infection Control Overview
- Infection occurs when microorganisms invade the body and cause illness.
- Key types of microorganisms:
- Viruses: Require a living host; e.g., common cold, hepatitis.
- Bacteria: Most common infection type; categorized by shape (cocci, bacilli, spirilla, spirochetes).
- Fungi: Plant-like organisms; e.g., athlete's foot, ringworm.
Chain of Infection
- Infection spreads through a cyclical process involving:
- Entry of microorganisms into the body.
- Growth and multiplication of microorganisms.
- Immune response, leading to signs and symptoms.
- Interruption of the chain can prevent infection spread.
Infection Prevention Strategies
- Standard Precautions (Tier 1): Used for all patients; assumes potential infection transmission from everyone.
- Transmission-Based Precautions (Tier 2): Implemented when standard precautions are inadequate; includes:
- Contact Precautions: For multi-resistant organisms and gastroenteritis.
- Droplet Precautions: For infections like pertussis and meningitis.
- Airborne Precautions: For diseases like TB and chickenpox.
Hand Hygiene Techniques
- Critical for infection prevention; follows '5 Moments':
- Before patient contact
- Before procedures
- After exposure to bodily fluids
- After patient contact
- After touching patient surroundings
- Hand washing duration: routine (40-60 seconds), aseptic (1 minute), surgical (5 minutes).
Personal Protective Equipment (PPE)
- Gloves: Protect hands; sterile gloves for aseptic procedures.
- Gowns: Shield skin and clothing from contamination.
- Masks and Face Protection: Prevent entry of pathogens through mucous membranes during procedures.
Aseptic Techniques
- Aseptic Non-Touch Technique (ANTT): Minimizes microorganism presence during healthcare procedures.
- Non-touch Technique: Protects key parts/sites from contamination by not touching them directly.
- Definitions of terms:
- Sterile: Free from microorganisms.
- Asepsis: Absence of pathogenic material.
- Clean: Free from dirt and stains.
Infection Control Guidelines
- Healthcare environments must adhere to infection control policies to minimize healthcare-associated infections (HAIs).
- Regular cleaning of patient care environments and equipment is essential.
- Education on respiratory hygiene and proper waste disposal is vital for infection control.
Summary of Transmission-Based Precautions
- Contact Precautions: Isolate patients; use gowns/gloves; limit movement.
- Droplet Precautions: Wear surgical masks; isolate in single rooms.
- Airborne Precautions: Special masks (N95); maintain strict isolation protocols.
Conclusion
- Effective infection control combines knowledge of transmission methods, rigorous hand hygiene, appropriate use of PPE, and adherence to established guidelines to protect patients and healthcare workers.
