Objective To review domestic and international studies regarding peripherally inserted central catheter related venous thrombosis （PICC-RVT） risk assessment tools through scoping review methodology, and to provide a basis for standardization of PICC-RVT risk assessment. Methods We systematically searched Chinese or foreign databases as well as guideline websites for li-terature on PICC-RVT risk assessment tools from database/website inception to November 26th, 2022. Results A total of 24 papers were finally included, and the types of risk assessment tools were divided into risk prediction models (n=14), risk assessment scales (n=8), thromboelastograms (n=1), and risk assessment systems (n=1).All 24 papers included disease factors,19 included treatment factors and 13 included catheter-related factors.Among the diseases or treatment factors, assessment items with a frequency of more than 10 counts included high-risk factors, D-dimer, history of venous thrombosis, and history of chemotherapy; among the catheter-related factors, the catheter-related complications (6 counts), catheter-vessel diameter ratio (6 counts), and catheter malposition (5 counts) were mentioned most frequently. Conclusion Disease factors and treatment factors are important elements of PICC-RVT risk assessments.There are various types of PICC-RVT risk assessment tools, but their reliability and validity remain to be further tested, and multi-center and large scale clinical application studies are needed.
