Background: Different scores have been recommended for symptomatic venous thromboembolism (VTE) risk assessment, however, there is a heterogeneity in the handling of these risk scores for the clinician.
Aims: To evaluate the effectiveness of an electronic decision support system for management of VTE in hospitalised patients.
Methods: An electronic decision support system for VTE risk assessment and integrated care (DeVTEare) based on hospital information system has been developed, which consisting of VTE, PE, and bleeding risk assessment ( Padua for medical patients, Caprini for surgical patients, Geneva, sPESI for PE, HAS-BLED), together with the guideline-recommended treatments. The DeVTEare was input in hospital information system in Sixth Medical Center, Chinese PLA General Hospital since August 1,2021. The VTE events were included into the study between January 1, 2021 to January 1,2022.
Results: There were 36005 adult patients (mean age,SD, 53,19, female, 47.1%) admitted to the hospital, and 169 (0.5%) inhospitalised DVT and 22 (0.1%) PE, respectively.
Using DeVTEare, the rate of VTE risk assessment was 98.5% for all in-hospital patients, the rate of PE risk assessment was 90.4% for patients at high-risk of VTE, the rate of preoperative PE risk assessment (Geneva score) was 94.4% , and the assessment rate of PE severity (sPESI) was 91.7% in patients admitted with PE (n=203,mean, SD, 66,15, female 42.4%), while bleeding risk assessment was 92.1%.
There were 34.8% patients receiving surgery and 8.1% inhospitalised medical patients at high risk of VTE. After adjusting age, sex, CAD, hypertension ,diabetes, cancer, etc. , the odd ratio (OR, 95% confidential interval, CI) of DeVTEare use was 0.58 (0.39-0.86) (p=0.007) for inhospitalised VTE, 0.64(0.49-0.84)(p=0.001) for the death of hospitalized VTE, and 0.58 (0.45-0.74)(p < 0.001) for the death of inhospitalised PE.
Conclusion(s): The electronic decision support system for VTE risk assessment and integrated care, DeVTEare, facilitated VTE prevention and reduced hospitalized VTE events.
