​Step 1: Review Occlusion Data to Identify Areas for Improvement

Element
Key Institutional Partners
  • Perform an audit to understand current drivers and patterns of occlusion at your facility
    • Use the CLOT tool to perform your audit to determine where occlusions are occurring (CLOT - Catheter flush, Lumens, Optimal access, Tip)
      • Remember, catheter occlusion can occur because of:
        • Mechanical problems with the catheter (kinking, pinch off)
        • Problems with the catheter caps
        • Formation of a fibrin sheath/tail within the catheter or around the tip of the catheter
        • Intraluminal thrombosis
        • Crystallization of mineral deposits (calcium, lipid, or dye) within the catheter causing physical obstruction
        • Mural or venous thrombosis around the catheter exit site
      • Strategies aimed to improve occlusion have to consider all of these possibilities
QI Team, Vascular Access Team
  • Identify which units or types of units (i.e. ICU vs non-ICU) have the highest rates of PICC-related catheter occlusion
    • Subsequent interventions in this toolkit should be focused on these patient care areas

  • Patient, Provider and Device Factors Associated with Catheter Occlusion
    • Patient: advanced age, elevated BMI, severe liver disease, diabetes, hemoglobin <10, ICU status
    • Provider:
      • Increased risk: left arm access, administration of cefepime/piperacillin-tazobactam/vancomycin, PICC use in the ICU setting, transfusion of PRBC (packed red blood cells)
      • Decreased risk: right arm access, verification of appropriate tip positioning, SASH method (flush with NS and lock with heparin) (SASH - Saline, Administer medication, Saline, Heparin)
    • Device Factors (strongest predictors of occlusion)- higher gauge, double lumen, triple lumen, catheter tip malposition at any point during dwell
