Evaluation of the usability of the digital platform navigator KardioUp for the journey of patients with chronic heart failure.

ABSTRACT

INTRODUCTION: Digital health interventions constitute a promising supplementary approach for further improvement of the quality and experience of cardiovascular care in patients with heart failure (HF). However, concerns about privacy, security, and quality may arise additionally to lack of personal motivation and accessibility to digital resources. Therefore, the proposed system aims to implement innovative technological trends in HF monitoring by recording clinical, biological, and biometric parameters. METHODS: The availability and feasibility of the digital platform KardioUp was evaluated in a group of 25 patients with HF (mean age 60 years) and 15 medical doctors (mean age 40 years) in two University Cardiology Clinics of the country. Connectivity of platform with the application and Android devices, use of alerts in clinical measurements, educational material provided, and total satisfaction by both patients and physicians were also evaluated. Patients with health barriers to understand the use of digital platforms or low eHealth ≤8 (digital unawareness) were excluded. RESULTS: All patients answered that the upload of measurements of blood pressure, blood glucose, and weight into the application were feasible. Patients mean eHealth score was 32,7. Additionally, the graphics of the application were friendly and educational material was also easily approached. Patients felt that this application can enable real patient-empowerment and self-management support. CONCLUSIONS: KardioUp was evaluated as a non-pharmacological intervention that could promote autonomous living of patients. Thus, possible alterations in daily activities and other parameters will be continuously evaluated providing metrics' monitoring on patients' performance, adherence to their treatment plan, avoidance of rehospitalizations, and overall health metrics.
