Background:
This network meta-analysis comprehensively compared the accuracy of the currently commonly used venous thromboembolism (VTE) assessment scale for screening peripherally inserted central catheter-associated VTE.
Methods:
We conducted a comprehensive literature search to obtain relevant studies on diagnostic accuracy. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias. ANOVA was performed via R software to implement diagnostic network meta-analysis via the Bayesian method to evaluate the predictive power of the dominance index.
Results:
A total of 9 studies were included, including 3837 patients, and involved 8 VTE assessment scales. The network meta-analysis showed that the Maneval scale had the highest superior index, followed by the Seeley scale, and the Michigan scale had the lowest superior index.
Conclusion:
Currently, limited evidence indicates that the Maneval scale and Seeley scale have good diagnostic test accuracy, and clinical medical staff can choose them preferentially when screening for peripherally inserted central catheter-associated VTE risks.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
