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.
