PreviewUnit 100: Nosocomial Infections and Infection Control in Healthcare Settings
1. Understanding Nosocomial Infections
- Definition of nosocomial infections (healthcare-associated infections)
- Types of pathogens causing nosocomial infections
- Bacteria (e.g., MRSA, Clostridium difficile)
- Viruses (e.g., Norovirus, Influenza)
- Fungi (e.g., Candida species)
- Risk factors contributing to nosocomial infections
- Patient-related factors (immunosuppression, age, underlying disease)
- Procedural factors (invasive devices, surgery)
- Environmental factors (contaminated surfaces, overcrowding)
2. Common Nosocomial Infections
- Urinary Tract Infections (UTIs)
- Causes and risk factors
- Clinical presentation
- Surgical Site Infections (SSIs)
- Types and classification
- Prevention strategies
- Pneumonia
- Ventilator-associated pneumonia (VAP)
- Pathogens involved
- Bloodstream Infections (BSIs)
- Central line-associated bloodstream infections (CLABSIs)
- Diagnosis and management
3. Transmission of Nosocomial Infections
- Modes of transmission
- Contact transmission (direct and indirect)
- Droplet transmission
- Airborne transmission
- Vector-borne transmission
- Infection control measures to prevent transmission
- Isolation precautions
- Environmental cleaning and disinfection
- Hand hygiene
4. Role of Healthcare Workers in Preventing Nosocomial Infections

- Encouraging vaccinations relevant to infection prevention
- Informing patients about their role during healthcare encounters
- Strategies to involve patients in infection control
8. Implementing Evidence-Based Practices
- Importance of guidelines and protocols
- Examples of evidence-based infection prevention practices
- Challenges in implementation and adherence
- Continuous quality improvement in infection control
9. Challenges and Future Directions in Preventing Nosocomial Infections
- Emerging pathogens and evolving resistance
