Risk factors for peripherally inserted central catheter-related venous thrombosis in adult patients with cancer.

ABSTRACT

PURPOSE: The purpose of this study was to understand and analyze the risk factors of peripherally inserted central catheter (PICC)-related venous thrombosis in adult patients with cancer. METHODS: This observational cohort study included adult patients with cancer who underwent color Doppler ultrasound at the Xiangya Hospital of Central South University, Hunan Provincial Maternal and Child Healthcare Hospital, and Xiangya Changde Hospital, Hunan Province, from January 1, 2017 to December 31, 2021. Univariate and multivariate logistic regression analyses were performed to determine the risk factors of PICC-related venous thrombosis. RESULTS: After risk adjustment, multivariate logistic regression analysis revealed statistically significant associations between PICC-related venous thrombosis and age > 65 years old (OR 1.791, CI 1.343-2.389), male sex (OR 1.398, CI 1.057-1.849), white blood cell count > 9.5 × 109 /L (OR 1.422, CI 1.041-1.942), APTT < 25 s (OR 2.006, CI 1.431-2.811), gastrointestinal tumor (OR 2.191, CI 1.406-3.414), infection (OR7.619, CI 5.783-10.037), the use of cisplatin (OR 2.374, CI 1.714-3.214), vincristine (OR 2.329, CI 1.447-3.749), the use of polyurethane (OR 2.449, CI 1.863-3.219) and open-ended catheters (OR1.660, CI 1.131-2.439), keeping time of the catheter (days) (OR 1.003, CI 1.001-1.005) were associated with PICC-related venous thrombosis. CONCLUSION: We identified that the presence of age > 65 years old, male sex, white blood cell count > 9.5 × 109 /L, APTT < 25 s, gastrointestinal tumor, infection, the use of cisplatin and vincristine, the use of polyurethane, open-ended catheters and keeping time of the catheter (days), were associated with PICC-related venous thrombosis.
