Assessment of Treatment Adherence and Associated Factors in Chronic HepB Patients Supported by HBVCare

Summary

Adherence to chronic Hepatitis B (HBV) treatment and regular follow-up visits is essential for preventing dangerous complications, yet adherence rates in Vietnam remain low due to barriers in patient awareness and geographic conditions. Digital health solutions, particularly mobile applications, have shown potential as tools for supporting patients in proactive disease management. The HBVCare mobile application was developed to provide features such as medication reminders, storage of lab results, and health education to improve treatment adherence and clinical outcomes. The investigators are conducting a multicenter, randomized controlled trial at Hoang Long Clinic and Hanoi Medical University Hospital to evaluate the effectiveness of HBVCare. Patients are randomized into either a control group receiving standard care and an intervention group using the HBVCare app, with patient adherence and related factors assessed after three months of treatment.
