Fibrinogen Levels and Challenges in Catheter Placement: Identifying Key Predictors of Early Bleeding at the Insertion Site Following PICC Placement

Overview

This study identifies lower fibrinogen levels and catheter advancement difficulty as independent risk factors for early bleeding following PICC placement. A tumor diagnosis was associated with a reduced risk of bleeding, but this finding should be regarded as hypothesis-generating rather than conclusive.

Background

PICC placement is a common procedure for long-term venous access, yet early bleeding at the insertion site can lead to significant complications and increased healthcare costs. Understanding the risk factors associated with this complication is essential for improving patient outcomes and developing targeted prevention strategies.

Data Highlights

Key Findings

• In-situ hemorrhage incidence was 21.9% among the study cohort.
• Lower fibrinogen levels were identified as an independent risk factor for early bleeding (OR = 0.762).
• Catheter advancement difficulty was also a significant predictor of bleeding (OR = 2.560).
• A tumor diagnosis was unexpectedly associated with a reduced risk of bleeding (OR = 0.331).
• The number of puncture attempts showed a trend toward significance in relation to bleeding risk (p = 0.060).

Clinical Implications

Pre-procedural assessment of fibrinogen levels may help identify patients at higher risk for bleeding complications following PICC placement.

Conclusion

Lower fibrinogen level and catheter advancement difficulty are independent risk factors for early PICC-related bleeding, while a tumor diagnosis appears protective.
