Using an Existing PICC Line in a Newly Admitted Patient
Prior to using a PICC line that is already in place when a patient is admitted to the hospital, radiographic verification of the PICC tip position is appropriate and necessary to ensure proper placement and safety. 1
Assessment Before Using an Existing PICC Line
When a patient is admitted with an existing PICC line, follow this algorithm:
Verify PICC tip position radiographically
- Radiographic verification is rated as appropriate after admission to a hospital with an existing PICC 1
- Confirm tip position is in the lower one-third of the superior vena cava, cavoatrial junction, or right atrium 1
- If tip position is in the upper or middle one-third of the superior vena cava or right ventricle, adjustment is appropriate 1
Assess catheter integrity and exit site
- Examine for signs of infection, dislodgement, or damage
- Check for wet, loose, or soiled dressings that require immediate changing 1
- Verify the external length marking matches documentation (if available)
- Assess for migration of the catheter
Review PICC documentation
- Date of insertion
- Original indication for placement
- Previous complications
- Type of catheter (single vs. multi-lumen)
Decision Making for PICC Use
When to Use the Existing PICC:
- Proper tip position confirmed radiographically
- No signs of infection or mechanical complications
- PICC is appropriate for the current clinical indication
When NOT to Use the Existing PICC:
- Signs of catheter-related bloodstream infection
- Improper tip position requiring adjustment
- Damaged catheter or compromised integrity
- PICC-related deep vein thrombosis
Important Considerations
Lumen Selection
- Use single-lumen devices when possible to reduce complications 1
- Multi-lumen PICCs should only be used when there is a documented rationale (e.g., multiple incompatible fluids) 1
- If using a multi-lumen PICC, dedicate one lumen exclusively for parenteral nutrition if applicable 1
Dressing Management
- Place sterile gauze between the PICC entry site and adhesive dressing for the first 1-2 days of insertion 1
- Use clear, transparent dressings thereafter that permit site examination 1
- Change dressings weekly or more frequently if wet, loose, or soiled 1
Catheter Maintenance
- Use normal saline rather than heparin to maintain catheter patency 1
- Never advance a migrated PICC; guidewire exchange is appropriate if needed 1
- Remove the PICC when it has not been used for clinical purposes for 48 hours or longer 1
Special Populations
For patients receiving tumor-infiltrating lymphocyte cell therapy, a PICC line is considered appropriate for delivery of the non-myeloablative lymphodepletion regimen, infusion of TIL cells, IL-2 administration, and subsequent supportive care measures 1.
For patients requiring long-term parenteral nutrition (>3 months), tunneled catheters are generally preferable to PICCs 1.
Complications to Monitor
Be vigilant for potential complications including:
- Catheter-related bloodstream infections (2.5% in hospitalized cancer patients) 2
- Deep vein thrombosis (3.6% in hospitalized cancer patients) 2
- Catheter occlusion (10% in hospitalized cancer patients) 2
- Embolic complications from improper placement 3
Key Pitfalls to Avoid
Failing to verify tip position: Always confirm proper placement radiographically before use 1
Using a PICC with signs of infection: Remove the PICC if there are signs of catheter-related bloodstream infection 1
Advancing a migrated PICC: Never attempt to advance a dislodged PICC; guidewire exchange is appropriate if needed 1
Using multi-lumen PICCs without clear indication: Default to single-lumen devices when possible to reduce complications 1
Neglecting dressing care: Ensure proper dressing maintenance to prevent infection 1
