Prevention bundles and checklists

CAUTI Prevention - Don't Break the Seal

• Aseptic Insertion: Utilize sterile technique and equipment for catheter placement.
• Maintain Closed Drainage: The primary prevention principle. The junction between the catheter and drainage tube must remain sealed.
• Appropriate Use Only: Limit use to strict indications (e.g., urinary obstruction, critical illness I/O monitoring, perioperative).
• Daily Review for Removal: Assess catheter necessity every day and remove it as soon as possible.

⭐ The most critical risk factor for CAUTI is the duration of catheterization. The risk of bacteriuria increases by 3-7% each day the catheter remains in place.

CLABSI Prevention - Keep the Line Clean

• Hand Hygiene & Aseptic Technique: Strict adherence before touching the line. Use maximal barrier precautions during insertion.
• Skin Antisepsis: Prep skin with >0.5% chlorhexidine in alcohol; allow to air dry completely before insertion.
• Line Maintenance & Access:
  • Perform daily dressing care with chlorhexidine-impregnated sponges.
  • "Scrub the Hub": Vigorously scrub needleless connectors and hubs with 70% alcohol or chlorhexidine for 15 seconds before every access.

⭐ Daily review of line necessity and prompt removal of non-essential catheters is the single most effective measure to prevent CLABSI.

VAP Prevention - Head Up, Lungs Clear

• Core Interventions (VAP Bundle):
  • Elevate head of bed to 30-45 degrees.
  • Daily sedation vacations and assessment of readiness to extubate (spontaneous breathing trials).
  • Oral hygiene with chlorhexidine rinse (e.g., q12h).
  • Deep Vein Thrombosis (DVT) prophylaxis.
  • Peptic Ulcer Disease (PUD) prophylaxis.

⭐ High-Yield: Daily reassessment of PUD prophylaxis (e.g., PPIs, H2 blockers) is crucial. While intended to prevent stress ulcers, acid suppression can alter gastric pH and potentially increase the risk of C. difficile or pneumonia.

SSI Prevention - The Sterile Surgical Field

• Core Principle: A sterile field is a designated area, created by sterile drapes, where only sterile items and personnel may be present.
• Team Conduct:
  • Scrubbed Personnel: Must keep hands in sight and above the waist. Only touch sterile items.
  • Non-scrubbed Personnel: Cannot enter the sterile field or touch sterile items.
• Maintaining Sterility:
  • Face the sterile field; never turn your back.
  • Moisture can cause "strike-through" contamination.
  • 📌 When in doubt, consider it contaminated.

⭐ The surgical gown is only considered sterile in the front, from the chest to the level of the sterile field, and the sleeves from the cuff to 2 inches above the elbow.

High‑Yield Points - ⚡ Biggest Takeaways

• Bundles are sets of evidence-based practices that, when performed collectively, significantly improve patient outcomes.
• Hand hygiene is the cornerstone of preventing all healthcare-associated infections (HAIs).
• CLABSI prevention hinges on aseptic technique, chlorhexidine skin prep, and daily review of line necessity.
• CAUTI prevention requires aseptic insertion, a closed drainage system, and prompt catheter removal.
• Key VAP prevention includes head-of-bed elevation (30-45°), daily sedation vacations, and oral care.
• SSI prevention involves timely preoperative antibiotics and maintaining normothermia and glycemic control.
