Sample interview questions: Explain your knowledge of central line-associated bloodstream infections (CLABSI) prevention in the ICU.
Sample answer:
- Knowledge of CLABSI Pathophysiology:
- Central line-associated bloodstream infections (CLABSIs) are infections of the bloodstream that occur within 48 hours to two weeks after the insertion of a central venous catheter (CVC).
- Common causative microorganisms include coagulase-negative staphylococci (CoNS), Staphylococcus aureus, and Enterobacteriaceae.
-
Risk factors for CLABSI include prolonged CVC insertion, poor hand hygiene, improper insertion techniques, and contamination of the catheter insertion site.
-
Prevention Strategies:
- Hand Hygiene:
- Adhere to strict hand hygiene protocols before and after touching the CVC or surrounding area.
- Use an alcohol-based hand rub or soap and water for handwashing.
- Proper Catheter Insertion:
- Strictly follow aseptic techniques during CVC insertion.
- Wear sterile gloves and gowns during the procedure.
- Cleanse the insertion site with an antiseptic solution.
- Choose the appropriate catheter size and insertion site.
- Catheter Maintenance:
- Regularly inspect the CVC insertion site for signs of infection, such as redness, swelling, or drainage.
- Replace dressings according to facility policy.
- Use antimicrobial-coated CVCs when appropriate.
- Avoid unnecessary catheter manipulation.
- Early Removal of Unnecessary Catheters:
- Remove CVCs as soon as they are no longer needed.
- Assess the patient’s condition daily to determine if the CVC can be removed.
-
Education and Training:
- Provide comprehensive education to healthcare providers about CLABSI prevention measures.
- Conduct regular training sessions on proper CVC insertion and maintenance techniques.
-
Recommended Practices:
- Use of Evidence-Based Guidelines:
