[Application and effect evaluation of the management system for whole process prevention and treatment of venous thromboembolism].

To establish and optimize the venous thromboembolism(VTE), whole process prevention and treatment information system based on electronic medical record system. Improving the convenience and efficiency of VTE prevention and control management to achieve continuous, dynamic, effective monitoring and other advantages of the management, reduce the incidence of VTE and improve medical quality and safety. Beijing Friendship Hospital established a hospital VTE prevention and treatment management system in 2020. Through the system management, it explores effective ways to prevent and manage VTE in hospitalized patients. This study took all hospitalized patients from January 1, 2020 to December 31, 2022 as the research subjects, and standardized diagnosis and treatment pathway was established based on clinical pathway. The hospital independently developed VTE prevention and management system, and built VTE assessment scales and risk assessment scales, based on the electronic medical record system of hospital information system. The relevant workload table is embedded in the electronic medical record. The system integrates clinical data, conducts unified analysis and structuring, realizes system functions such as VTE risk assessment, VTE risk warning, VTE standardized prevention and treatment, VTE quality control, etc. And evaluates and analyzes the implementation effect of the VTE prevention and management system in the hospital, comparing the VTE prevention and management effect of hospitalized patients before and after system management. The results showed that the medical staff's awareness and ability of prevention and treatment of VTE were significantly improved. In 2020, the rate of VTE dynamic risk assessment reached to 55.9%, and which was increased to 88.0% in 2022(<i>χ</i>²=15 551.302,<i>P</i><0.001). In 2020, the rate of VTE preventive measures was 22.8%, which was increased to 61.2% in 2022(<i>χ</i>²=4 669.675,<i>P</i><0.001). In conclusion, the application of the hospital VTE prevention and treatment management system can effectively improve the standardization, scientific and management efficiency, which further ensure medical safety, and provide necessary decision support for clinical medicine.
