PB0434 - Smart technology facilitated patient-centered venous thromboembolism management: pilot study on the digital feasibility

Background: The design quality of digital tool is challenging for the digital health, however, which is rarely completely assessed.

Aims: This study aimed to evaluate the feasibility of a mobile health app designed to support self-management for patients with venous thromboembolism (VTE) or at risk of VTE (mVTEA).

Methods: This was a pilot study of VTE or moderate-to-high-risk VTE patients over 18 years old enrolled in Chinese PLA General Hospital between August 25 and December 20, 2023. The digital health record, patient’s acceptance, quality, and usability were evaluated. The verified Chinese versions of the Mobile Application Rating Scale (C-uMARS) and mHealth APP Usability Questionnaire (C-MAUQ) were used to evaluate quality and usability at one month, respectively. Trial registration: www.chictr.org.cn, no. ChiCTR2200063206.

Results: Out of 88 patients (age: 63.85±15.41 years, 23 female, 26.14%), 30 (2 [6.67%] at high-risk VTE, 28 [93.33%] with VTE) were included in the final analysis. Over 80% of patients enjoyed the 3D digital “human” health records and fluent manipulation. For the quality assessment, the C-uMARS score of the “information”, “functionality”, and “engagement" were 3.90±0.85, 3.97±0.82, and 3.97±0.86, respectively. About one third patients rated excellent for the “information”, “functionality”, and “engagement”. But, 42.9%, 37.5%, and 41.1% patients felt the medium-level acceptability of “functionality”, “engagement”, and “information”, respectively. For the usability assessment, the C-MAUQ score were 1.76±0.82: 1.85±0.89 for "ease of use and satisfaction", 1.81±0.92 for "system information arrangement", and 1.63±0.70 for "usefulness". Over 80% patients agreed or extensively agreed "ease of use and satisfaction", while 81% for "system information arrangement", and 86% for "usefulness".

Conclusion(s): The mVTEA demonstrated good digital feasibility for patients with VTE or at risk of VTE, especially with the digital health record and the usability of the App.
