The data received were evaluated every day by a geriatrician. The monitor system displayed an alert when a measurement was outside a predetermined range. In case of abnormal readings, the physician contacted the patient to verify whether their symptoms had worsened or new symptoms had arose. In this event, the patient's adherence to therapy was checked and, if unsatisfactory, individually tailored interventions promoting adherence were carried up. Otherwise, an once appointment (for patients with milder abnormalities or symptoms) or a hospital admission was scheduled.
