Abstract：Objective To study the application effect of intelligent early warning system of hospital venous thromboem-bolism (VTE)
risk assessment in the prevention of deep venous thrombosis in patients with hip fracture. Methods A total of 174 hospitalized
patients with hip fracture before the application of intelligent early warning system of VTE risk assessment in the hospital from
March 2019 to December 2019 were selected as the pre-application group, 141 hospitalized patients with hip fracture after the use
of the system from January to October 2020 were selected as the post-application group.The assessment rate of thrombosis risk,
the assessment rate of bleeding risk, the implementation rate of physical preventive measures, the incidence rate of thrombosis, the
screening rate of color ultrasound and the mortality rate were compared between the two groups. Results After the application of
intelligent early warning system of hospital VTE risk assessment, the rate of thrombosis risk assessment in patients with hip fracture
increased from 64.94% before the application of the system to 97.16%, the rate of bleeding risk assessment increased from 51.15%
to 87.23%, the actual rate of physical preventive measures increased from 59.20% before the application of the system to 78.72%,
the screening rate of color ultrasound increased from 74.14% before the system application to 85.82%, with statistical significance
(P<0.05). The incidence of thrombosis increased from 15.50% to 15.70%, but there was no statistical significance (χ2=0.002,
P>0.05). The all-cause mortality rate of patients decreased from 20.53% to 10.45%, and the difference was statistically significant
(χ2=5.427, P<0.05). Conclusion The intelligent early warning system of hospital VTE risk assessment had the advantages of early
warning, real-time monitoring and timely disposal, etc. Its application could effectively standardize the management of hospital VTE,
reduce the mortality rate of patients with hip fracture, and improve the medical quality. Therefore, it is worthy of clinical promotion.
