Study Notes
Focus of Healthcare Epidemiology
- Primary focus is on preventing and controlling Healthcare-Associated Infections (HAIs)
Practices and Activities Covered by Healthcare Epidemiology
- Surveillance for HAIs
- Outbreak investigation and control
- Development and implementation of infection prevention and control practices
- Education and training of healthcare personnel
- Collaboration with other healthcare professionals
Healthcare-Associated Infections (HAIs)
- Infections that occur in patients during the course of receiving healthcare treatment
- Examples: nosocomial infections, surgical site infections, catheter-associated urinary tract infections, ventilator-associated pneumonia
Iatrogenic Infections
- Infections caused by medical or surgical treatment
- Examples: hospital-acquired infections, surgical site infections
Nosocomial Infections
- Common type: urinary tract infections
- Major contributor: inadequate hand hygiene
- Examples: ventilator-associated pneumonia, surgical site infections, catheter-associated urinary tract infections
Pathogens
- Staphylococcus aureus: highly pathogenic and resistant to antibiotics
- Coagulase-negative staphylococci: less pathogenic and more resistant to antibiotics
- Legionella: found in wet environments, associated with respiratory tract and bloodstream infections
- Escherichia coli: part of the normal flora in the colon, associated with intra-abdominal, liver, and urinary tract infections
- Enterobacteriaceae: major global public health concern, includes bacteria producing extended spectrum β-lactamases (ESBLs) and carbapenemase-producing Enterobacteriaceae (CPEs)
- Pseudomonas aeruginosa: resistant to antibiotics and sterilization techniques, found in wet environments, causes respiratory tract and bloodstream infections
- Clostridioides difficile: causes antibiotic-associated diarrhea (AAD) and pseudomembranous colitis (PMC)
Factors Contributing to Nosocomial Infections
- Inadequate hand hygiene
- Increased use of antibiotics
- Presence of invasive devices (e.g., central lines, ventilators)
