1. CDC Central Line Insertion & Maintenance Audit Domains

The CDC Healthcare Infection Control Practices Advisory Committee (HICPAC) establishes 5 inviolate infection reduction domains:

HICPAC Core Audit Domains:

  • 1. Strict Hand Hygiene: Alcohol-based hand rub or soap wash prior to palpation, insertion, replacement, or dressing changes.
  • 2. Maximal Sterile Barrier Precautions: Cap, mask, sterile gown, sterile gloves, and full-body fenestrated patient drape for all central line and PICC insertions.
  • 3. 2% Chlorhexidine Skin Preparation: 2% CHG in 70% IPA with 30-second active friction scrub and mandatory 2-minute complete air dry.
  • 4. Optimal Catheter Site Selection: Subclavian site preference over internal jugular and femoral veins in adult patients.
  • 5. Daily Catheter Necessity Review: Multi-disciplinary daily rounds evaluating continued line indication and prompt removal of unneeded lines.

2. Intravenous Administration Set Replacement Intervals

TABLE 1: CDC STANDARDIZED ADMINISTRATION SET REPLACEMENT SCHEDULES
CDC Guidelines · INS Standard 37 Compliance
Administration Set Type Maximum Allowable Dwell Time Rationale & Microbial Risk
Continuous Crystalloid Infusions Every 7 days (168 hours) Extended dwell does not increase infection rates; reduces touch contamination events.
Intermittent Medication Infusions Every 24 hours Frequent disconnects increase intraluminal bacterial inoculation.
Total Parenteral Nutrition (2-in-1) Every 24 hours High dextrose concentrations foster bacterial and fungal proliferation.
Intravenous Lipid Emulsions (ILE / 3-in-1) Every 12 to 24 hours Lipid emulsions rapidly support fungal growth (Candida albicans).
Blood & Blood Products Every 4 hours or 4 units Bacterial proliferation and protein mesh clogging within filter chamber.
