VTE风险评估智能预警系统在髋部骨折患者深静脉血栓预防中的应用

Application of Intelligent Early Warning System of VTE Risk Assessment in Prevention of Deep Venous Thrombosis in Patients with Hip Fracture

目的研究静脉血栓栓塞症(Venous Thromboem-bolism,VTE)风险评估智能预警系统在髋部骨折患者深静脉血栓预防中的应用效果。方法将2019年3—12月VTE风险评估智能预警系统应用前的髋部骨折患者174例分为应用前组;将2020年1—10月系统使用后的髋部骨折患者141例分为应用后组,比较两组患者血栓风险评估率、出血风险评估率、物理预防措施落实率、血栓发生率、彩超筛查率及全因死亡率。结果应用VTE风险评估智能预警系统后,髋部骨折患者血栓风险评估率从系统应用前的64.94%上升至97.16%;出血风险评估率由系统应用前的51.15%上升至87.23%;物理预防措施落实率由系统应用前的59.20%上升至78.72%;彩超筛查率由系统应用前的74.14%上升至85.82%,差异均有统计学意义(P<0.05);系统应用后彩超筛查率明显上升,血栓发生率由应用前的15.50%上升至15.70%,差异无统计学意义(χ2=0.002,P>0.05);患者的全因死亡率从20.53%下降至10.45%,差异有统计学意义(χ2=5.427,P<0.05)。结论 VTE风险评估智能预警系统具有早期预警、实时监控、及时处置等优点,它的应用有效规范了医院VTE的管理,降低了髋部骨折患者的死亡率,提高了医疗质量,值得临床推广。

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.
