Study Notes
Healthcare-associated Infections (HAIs)
- HAIs are infections acquired during healthcare delivery in any setting.
- Approximately 2,000,000 HAIs occur annually in the U.S., resulting in 100,000 deaths.
- One-third of HAIs are preventable, costing approximately $6.65 billion each year.
Transmission of Infections
- Infection transmission requires a source, susceptible host, and mode of transportation.
- Primary transmission methods include human contact and contaminated inanimate objects.
Factors Increasing Susceptibility
- Patients with underlying diseases or immunocompromised conditions (e.g., chemotherapy, AIDS) are more susceptible to infections.
Modes of Transmission
- Direct Contact: Body surface to body surface (e.g., HIV, influenza).
- Indirect Contact: Via contaminated objects (e.g., Hepatitis B and C).
- Droplet Transmission: Larger droplets (>5 micrometers) from coughing or sneezing (e.g., rubella).
- Airborne Transmission: Microorganisms suspended in the air (e.g., tuberculosis).
- Vehicle Transmission: Through contaminated food, water, or devices (e.g., cholera).
- Vector-Borne Transmission: Via vectors like mosquitoes (e.g., malaria).
Strategies for Protection
- Infection Control Procedures: Reduce the spread of infections.
- Proper PPE: Essential for protecting healthcare workers and patients.
- Immunization Programs: Vaccination for healthcare workers against specific diseases.
- Safety Training: Educating staff on infection control protocols.
- Employee Health Policies: Sick employees should not work with potentially infectious conditions.
Equipment Processing and Disinfection
- Classification of equipment:
- Critical Equipment: Must be sterile (e.g., chest tubes).
- Semi-Critical Equipment: Requires disinfection (e.g., ventilator components).
- Non-Critical Equipment: Can be cleaned (e.g., office equipment).
Disinfection Methods
- Cleaning: Removal of visible contamination to reduce microorganisms.
- Disinfection: Reduces microorganisms but doesn't eliminate all, particularly spores.
- Sterilization: Complete elimination of all microorganisms, including spores.
- Monitoring: Ensures effectiveness of cleaning and disinfection.
Disinfection Methods and Agents
- Pasteurization: Equipment immersed in water at 70°C for 30-45 minutes.
- Chemical Disinfectants: Include alcohol, glutaraldehyde (high-level), hydrogen peroxide, and acetic acid.
Sterilization Techniques
- Physical: Steam and radiation.
- Chemical: Ethylene oxide, hydrogen peroxide gas plasma, and peracetic acid.
Personal Protective Equipment (PPE)
- Includes gloves, gowns, masks, and eye protection.
- Crucial for the safety of healthcare workers during patient care.
Standard Precautions
- Apply to all patients, emphasizing hand hygiene, appropriate PPE, and safe disposal of contaminated materials.
- Includes using mouthpieces during resuscitation and handling textiles to prevent microorganism transfer.
Transmission-Based Precautions
- Contact Isolation: For patients with MRSA or ulcers, requiring private rooms and gloves.
- Droplet Isolation: For influenza and meningitis, needing masks within 3 feet of the patient.
- Airborne Isolation: For tuberculosis and COVID-19, requiring N95 masks and negative pressure rooms.
Importance of Hand Hygiene
- Considered the most effective measure against infection spread.
- Alcohol-based hand rubs are effective, especially when hands are visibly soiled.
Infection Control Measures
- Regular monitoring and adherence to infection control protocols significantly reduce incidence rates of HAIs.
- Effective infection control methods include cleaning, disinfecting, and sterilizing equipment and environments.
