PICCs are high-risk devices — CLABSI from a poorly maintained PICC costs $46,000 per event on average and can be fatal in immunocompromised patients.

PICC vs. Other Central Lines: Quick Reference

Line Type	Insertion Site	Tip Location	Dwell Time
PICC	Basilic/brachial vein (upper arm)	Lower SVC / CAJ	Months to years
Central venous catheter (CVC)	IJ / subclavian / femoral	Lower SVC / RA	Days to weeks
Midline catheter	Basilic/brachial vein	Does NOT reach central circulation	2–4 weeks
Implanted port	Subcutaneous pocket, chest	Lower SVC / CAJ	Years

Confirming PICC Tip Position

PICC tip must be confirmed in the lower third of the SVC or cavoatrial junction (CAJ) — NOT in the right atrium (arrhythmia risk) and NOT in a peripheral vein (cannot infuse vesicants or hyperosmolar solutions safely). Confirmation method: chest X-ray read by a provider before use. Intravascular ECG guidance is used during bedside insertion at some facilities. Never use a PICC without confirmed tip position documented in the chart.

CLABSI Prevention Bundle (PICC-Specific)

Hand hygiene: WHO 5 moments — before every PICC access
Dressing: Transparent semipermeable dressing changed every 7 days (or when soiled/loose); chlorhexidine-impregnated disc at insertion site
Hub disinfection: Scrub the hub ≥15 seconds with 70% alcohol before every access — "scrub the hub" is not optional
Needleless connector change: Every 72–96 hours per your hospital policy
Tubing change: Every 96 hours (lipid-containing solutions: every 24h)
Daily necessity assessment: Document daily why the PICC is still needed — remove when no longer necessary

PICC dressing change: Sterile technique, sterile gloves, mask on patient and nurse. Never use non-sterile gloves for PICC dressing changes. CLABSI prevention is a nursing-controlled outcome.

Blood Draws from a PICC

Most PICC lines can be used for blood draws if lumen size permits (≥4 French). Procedure: stop all infusions, discard 5–10 mL blood (waste), draw sample, flush with 10 mL NS, resume infusions. Never draw blood for culture from the PICC line being evaluated for possible CLABSI — draw peripherally to avoid false positives.

Complication Recognition

CLABSI: Fever, chills, hypotension with no other source → blood cultures × 2 (one from PICC, one peripheral) → notify provider → do NOT routinely pull the line until cultures result unless septic.

Thrombosis: Upper extremity edema, pain, erythema along vessel course → Doppler ultrasound → anticoagulation if confirmed DVT.

Tip migration: Arrhythmias during infusion, back pain, ear sounds with flushing → chest X-ray to confirm tip position → notify interventional radiology.

Occlusion: Cannot infuse, cannot aspirate → attempt alteplase 2 mg dwell per protocol → do NOT force flush an occluded PICC.
