    Exploring Opportunities for Social Infrastructure in Congestive Heart Failure Management
    (2015) Gajos, Krzysztof; Kim, Sunyoung; Iravantchi, Yasha; Grosz, Barbara
    As population ages and chronic disease increases, new models of health care delivery are inevitable. We propose to interweave the concept of chronic care management into social infrastructure to better support elderly individuals with chronic diseases. As an exemplar, we chose and investigated Congestive Heart Failure (CHF), since it is one of serious health threats among the elderly population in western society. From a preliminary investigation of literature and prior work, we suggest two implications for social care of chronic patients: increased social awareness, and social knowledge base. This is not an exhaustive list of implications, but a starting point to open up discussions towards social care for chronic diseases.

    SwellFit: a Wearable Sensor for Patients with Congestive Heart Failure
    (2016) Kim, Sunyoung; Iravantchi, Yasha; Gajos, Krzysztof; Grosz, Barbara
    Congestive heart failure (CHF) is the most common reason for hospitalization in people aged 65 years and older in the United States. Especially, a very high rate of unplanned readmissions within 30 days of discharge due to CHF occurs a heavy associated financial burden and degraded quality of care. To effectively prevent CHF readmission and improve overall care, this paper proposes SwellFit, a novel wearable sensor that helps outpatients to proactively monitor a physical symptom of worsening CHF, ankle swelling. Using a flex sensor, SwellFit monitors changes in ankle curvature as an indication of swelling. A pilot test with 4 adults showed that SwellFit successfully distinguish noise data and motion artifacts from ankle swelling. Collaborating with cardiac experts, we are currently planning to test SwellFit with hospitalized CHF patients who have swelling conditions to demonstrate the feasibility and reliability of SwellFit on detecting swelling from ankle curvature.
