The Homey dialog system has been developed to supplement face-to-face encounters in the process of care of chronic diseases: the current prototype targets the care of Hypertension and integrates a general-purpose electronic patient record (EPR) and a state-of-the art dialogue engine. Patients report their health condition from their home via an intelligent dialog system (IDS), and care-giving professionals can receive timely information about their state, right at the point of care. Homey is currently ongoing clinical evaluation. This paper provides an overview of the system, and presents preliminary results obtained from the usage patterns collected in the ongoing clinical trial. Finally, conclusions are drawn on the utility and prospective uses of the data collected.
