Patients were followed-up for 3 months after discharge, collecting emergency visits and readmissions due to a new heart failure exacerbation. Those patients in the intervention group used a commercial telemedicine system: Careline H@me, which was provided by the company SALUDNOVA. They system was personalized by adding the functional status monitoring capabilities. Thus, the system collected vital signs (i.e. blood pressure, heart rate, respiratory rate, oxygen saturation, glucose, and weight); symptoms of decompensated heart failure (i.e. dyspnoea and orthopnoea); and functional status (i.e. part of the Short Physical Performance Battery, SPPB) and a brief questionnaire (i.e. Do you have the medication?) every 48 hours.
