Analysis of risk factors for PICC-related venous thrombosis in patients with hematological malignancies and establishment of a nomogram prediction model

In this study, we identified independent risk factors for CRT following PICC placement in patients with hematologic malignancies and developed a predictive model to assess CRT risk. The model demonstrated good discrimination, calibration, and clinical utility, enabling individualized risk assessment and intervention strategies to improve chemotherapy safety and extend PICC use duration.
