Study Notes
Healthcare Epidemiology
- Studies the occurrence, determinants, and distribution of health issues within healthcare settings.
- Covers various settings: hospitals, clinics, rehabilitation centers, long-term care facilities, and hospices.
- Aims to protect patients, staff, and visitors from infections.
- Involves practices like infection prevention and control (IPC), surveillance measures, risk reduction programs, policy development, and staff education.
- Includes cost-benefit assessment of prevention programs.
Important Definitions
- Healthcare-onset infections: Infections appearing within healthcare settings, regardless of source.
- Community-associated infections: Infections acquired outside healthcare facilities.
- Healthcare-associated (nosocomial) infections (HAIs): Infections acquired inside healthcare facilities; includes infections not present at admission or developing within 14 days of discharge.
- Iatrogenic infections: Infections resulting from medical or surgical interventions.
Nosocomial Infections
- Common types include urinary tract infections (especially with catheters), surgical wound infections, lower respiratory tract infections, and bloodstream infections.
Factors Contributing to Nosocomial Infections
- Increased drug-resistant pathogens due to antibiotic overuse.
- High number of immunocompromised patients.
- Failure to follow infection control guidelines.
Microbial Causes of Nosocomial Infections
- Gram-positive cocci: Staphylococcus aureus (including MRSA) and coagulase-negative staphylococci.
- Gram-negative bacilli: Enterobacterales (like E. coli and Klebsiella), Pseudomonas aeruginosa, and Acinetobacter.
- Clostridioides difficile: A spore-forming bacterium causing antibiotic-associated diarrhea and pseudomembranous colitis.
Chronic Diseases and Conditions
- Conditions like cystic fibrosis, renal dialysis, and paralysis—which may contribute to nosocomial infections.
- Immunosuppressive situations and therapies.
- Devices like endotracheal tubes, central venous or arterial catheters—increasing exposure risk.
Steps to Fight Antimicrobial Resistance
- Vaccination, targeted pathogen treatment, expert consultation, antimicrobial control practices, effective infection treatment strategies and policies, and a thorough understanding of infection sources and contamination in healthcare facilities.
Precaution Protocols
- Protective isolation for immunocompromised patients to reduce chance of exposure to pathogens.
- Source isolation for patients who are potential sources of infection.
- Standard precautions for all patients in all healthcare settings.
Transmission-Based Precautions
- Airborne precautions for infections spread by airborne particles (e.g., tuberculosis, COVID-19).
- Droplet precautions for infections spread by large droplets (e.g., influenza).
- Contact precautions for infections spread by direct or indirect contact (e.g., MRSA, C. difficile).
Infection Control Activities
- Hand Hygiene: Essential practice for prevention in all protocols (Ayliffe technique recommended).
- Personal Protective Equipment (PPE): Gloves, gowns, eye protection, respirators.
- Laundry protocols: Proper handling for contaminated linen.
- Environmental cleaning and waste disposal: Proper procedures for cleaning surfaces and handling potentially infectious waste.
- Prevention of needlestick and sharps injuries: Appropriate disposal protocols and safe handling practices.
Patient Placement and Transport
- Single rooms for transmission-based precautions.
- Minimizing exposure time outside the room.
- Negative pressure rooms for airborne infections.
- Positive pressure rooms for infections where the patient is a possible source.
Personal Protective Equipment (PPE)
- Proper sequence for donning and doffing (removing) PPE.
- Appropriate use for different situations (e.g., contact vs. airborne).
Personal Care Equipment
- Spaulding Classification System: Categorizing equipment according to the level of risk for infection transmission (critical, semi-critical, non-critical).
- Using appropriate disinfection and sterilization methods for each category.
