Abstract:

Objective To construct and validate a tool for risk assessment of PICC associated venous thrombosis to provide scientific basis for rapidly improving recognition rate of PICC-related thrombosis.Methods Combining with relevant literature,item pool of risk assessment tool for PICC-related thrombosis was established. By Delphi Method and analytic hierarchy process （AHP）,the risk assessment index system of PICC-related thrombosis was established. A total of 130 cancer patients were investigated to test reliability and validity. ROC curve was constructed to identify the critical value and corresponding recognition capacity.Results The risk assessment index system of PICC-related thrombosis included 3 first-level indicators,and 22 second-level indicators. The Cronbach’s alpha of three dimensions,as well as the whole scale were 0.805,0.683,0.751,and 0.794 respectively. The results of ROC curve showed that AUC was 0.728 [P=0.013,95%CI（0.594,0.862）],The best high-risk critical value was 5.5,while corresponding sensitivity was 0.909,and specificity was 0.471.Conclusion The PICC-related venous thrombosis risk assessment scale has good reliability and validity,which can be used as an assessment tool for screening risks of venous thrombosis in PICC patients during clinical practice.
