Background: Anticoagulant prescription and management are crucial steps of management of venous thromboembolism (VTE). The Clinical decision support systems (CDSS) are designed and developed to aid healthcare professionals in making informed decisions.

Aims: To develop and assess the efficacy the mobile app-based CDSS for the management of VTE

Methods: A randomized controlled trial was conducted, enrolling participants aged 20 years or older who were one of the following categories: medical student, intern, internal medicine resident, or hematology fellow. Participants were randomly assigned to either app-based CDSS or control groups. Participants were tasked with prescribing or planning the management of 15 clinical vignettes. The primary outcome was the mean score, comparing between the app-based CDSS and control groups. Satisfaction was assessed.

Results: From September 2023 through November 2023, a total of 126 participants were enrolled with the mean age of 25.3±3.0 years. The mean score of participants in app-based CDSS group was significantly higher (14.4±0.8) compared with those in control group (6.2±2.6) with a mean difference of 8.2, 95% CI 7.5-8.9, p< 0.001. Satisfaction was evaluated in 63 participants in app-based CDSS group. The mean score was 4.57±0.49 for accessibility, 4.73±0.45 for app stability, 4.94±0.25 for user interface, 4.78±0.42 for simplicity, 4.98±0.13 for assistance in decision-making and 4.90±0.30 for overall satisfaction.

Conclusion(s): App-based CDSS (DECIDE-COAG®) demonstrates a significant improvement in the performance of healthcare professionals regarding anticoagulant prescriptions and VTE management. Further studies that specifically investigate the clinical benefits of app-based CDSS in real-world clinical practice are warranted.
