Study Notes
Health Care-Associated Infections (HAIs)
- Infections acquired after admission to a health care facility not present at the time of admission.
- Patients in healthcare settings are vulnerable due to high illness acuity and aggressive treatments that may compromise immunity.
- Antibiotic-resistant organisms can spread in facilities due to close proximity of susceptible patients often receiving antibiotics.
- Clostridioides difficile infection (CDI) is among the most prevalent HAIs and can be costly.
- C. difficile is a Gram-positive, spore-forming bacillus that produces toxins A and B, leading to diarrhea and colitis.
- Pseudomembranous colitis (PMC) is a severe manifestation of CDI characterized by severe colitis.
Infection Control Practices
-
Contact Isolation:
- Essential for minimizing infection spread; involves placing patients under isolation protocols.
- Hand hygiene is vital, especially using soap and water for patients with diarrhea.
- Use of gloves and gowns to prevent contamination.
- Performing thorough environmental cleaning to eliminate pathogens.
-
Antibiotic Stewardship:
- Important preventive measure focusing on proper antibiotic use to reduce resistance.
-
Catheter Insertion:
- Aseptic techniques and critical thinking during catheterizations can reduce nosocomial infection rates.
Causes of HAIs
-
Exogenous Infections:
- Result from microorganisms outside the body that are not part of the normal flora, such as Salmonella and Clostridium tetani.
-
Endogenous Infections:
- Arise from microorganisms that exist normally in the body but proliferate due to disruptions in the normal flora, including enterococci, yeasts, and streptococci.
- Enterococci can migrate from the gut to the skin, leading to wound infections.
Risk Factors for HAIs
-
Patient Health:
- Older adults and those with chronic diseases or pre-existing disabilities are more at risk.
-
Healthcare Staff:
- The higher the number of healthcare workers involved with a patient, the greater the risk of infection transmission.
-
Healthcare Facility:
- Prolonged hospital stays, invasive procedures, and the nature of therapies administered influence infection likelihood.
Major Sites for HAIs
- Commonly affected areas include:
- Surgical wounds
- Traumatic wounds
- Urinary tracts
- Respiratory tracts
- Bloodstream
Potential Outcomes of HAIs
- Reduced quality of life for affected patients.
- Increased financial burdens on the healthcare system due to extended treatment needed.
- Prolonged recovery times, leading to extended hospitalizations.
Summary
- Infection prevention is crucial for delivering high-quality patient care.
- Healthcare professionals must understand infection control practices, risk factors, and potential outcomes of HAIs.
- Utilizing critical thinking and strict aseptic techniques is essential to minimize patient risks.
