Abstract
Adequate adherence to treatment is indispensable in preventing adverse consequences in heart failure patients. Such adherence can be managed through heart failure clinics and various methods of follow-up. In recent years, the use of telemonitoring has shown promising benefits in supporting clinicians' follow-up, as well as contributing to patients' self-care. This article presents the development and evaluation of a telemonitoring application for heart failure, through a Web-based interface for clinicians and a mobile application for patients. The application was evaluated through a 6-month pilot observational descriptive study in 20 outpatients with reduced ejection fraction and two nurses, in the context of a heart failure clinic. A technological acceptance questionnaire was applied to all patients and nurses at the end of the study period. In use, the application generated 64 real-time alerts for early decision-making to prevent complications, and 91% of patients did not present hospital readmissions. Such results, along with high user acceptance, show potential utility of the application as an effective complementary strategy for follow-up of patients with heart failure.
