Objective To develop a risk assessment system for Peripherally Inserted Central Catheter Related Ve-nous Thrombus(PICC-RVT)in patients with hematological diseases.Methods PICC-RVT related literature was retrieved and initial index pool was established.Through group discussion,the PICC-RVT risk assessment indexes of patients with hematological diseases were preliminarily developed.Two rounds of expert correspondence were conducted by Delphi method,and the index weights were determined by analytic hierarchy process.Results The positive degree of the two rounds of correspondence consultation with experts was 100%and 88.0%,the expert authority coefficient was 0.831 and 0.925,and the Kendall's W coefficient was 0.227 and 0.364,respectively.The final PICC-RVT risk assess-ment system for patients with hematological diseases contains 4 first-level indicators,13 second-level indicators and 43 third-level indicators.Conclusion The established PICC-RVT risk assessment system for patients with hema-tologic diseases is scientific and provides a tool for assessing the risk of PICC-RVT in patients with hematologic disea-ses.Patients,treatments,catheters,and procedures are key aspects of PICC-RVT risk assessment in patients with he-matologic diseases.
