In a typical aging-in-place setting, electronic medical record, telemedicine data, and sensor data are used by different groups of decision makers, but the data may not be viewed in a holistic display to promote clinical decision making. Employing a user-centered design and evaluation framework, we analyzed relational data displays of congestive heart failure and provided an in-depth description of user characteristics, preferences, systems functionality, basic tasks and effective representations in such an information distributed setting. As a result, the prototypical design demonstrates our effort toward an integrated data display for chronic disease management in long-term care and clinical decision support which would enhance aging in place.
