Results: Since the application of the VTE early warning information system, VTE risk assessment had been given to all the hospitalized patients with the assessment rate reaching 100.00%. The prevention rates of basic, physical and drug preventive measures in high-risk patients increased significantly (P<0.001). Among the four dimensions of user experience evaluation of the information system, the dimension of early and timely warning scored the highest (9.16±2.79).
