    Activity Theory Analysis of Heart Failure Self-Care
    (Taylor & Francis, 2018) Cornet, Victor; Voida, Stephen; Holden, Richard J.; Medicine, School of Medicine
    The management of chronic health conditions such as heart failure is a complex process emerging from the activity of a network of individuals and artifacts. This article presents an Activity Theory-based secondary analysis of data from a geriatric heart failure management study. Twenty-one patients' interviews and clinic visit observations were analyzed to uncover eight configurations of roles and activities involving patients, clinicians, and others in the sociotechnical network. For each configuration or activity pattern, we identify points of tension and propose guidelines for developing interventions for future computer-supported healthcare systems.

    Human factors analysis, design, and evaluation of Engage, a consumer health IT application for geriatric heart failure self-care
    (Taylor & Francis:, 2017) Srinivas, Preethi; Cornet, Victor; Holden, Richard; BioHealth Informatics, School of Informatics and Computing
    Human factors and ergonomics (HFE) and related approaches can be used to enhance research and development of consumer-facing health IT systems, including technologies supporting the needs of people with chronic disease. We describe a multiphase HFE study of health IT supporting self-care of chronic heart failure by older adults. The study was based on HFE frameworks of "patient work" and incorporated the three broad phases of user-centered design: study or analysis; design; and evaluation. In the study phase, data from observations, interviews, surveys, and other methods were analyzed to identify gaps in and requirements for supporting heart failure self-care. The design phase applied findings from the study phase throughout an iterative process, culminating in the design of the Engage application, a product intended for continuous use over 30 days to stimulate self-care engagement, behavior, and knowledge. During the evaluation phase, we identified a variety of usability issues through expert heuristic evaluation and laboratory-based usability testing. We discuss the implications of our findings regarding heart failure self-care in older adults and the methodological challenges of rapid translational field research and development in this domain.

    Uncertainty Management Among Older Adults with Heart Failure: Responses to Receiving Implanted Device Data using a Fictitious Scenario Interview Method
    (Sage, 2019) Daley, Carly; Cornet, Victor; Patekar, Gauri; Kosarabe, Swapnil; Bolchini, Davide; Toscos, Tammy; Mirro, Michael; Wagner, Shauna; Martin, Elizabeth; Ghahari, Romisa Rohani; Ahmed, Ryan; Miller, Amy; Holden, Richard J.; Medicine, School of Medicine
    Heart failure (HF) is a complex chronic illness that affects the older adult population, requiring medical therapy and day-to-day management to prevent worsening and exacerbation. Patients with HF are often treated with cardiac implanted electronic devices (CIEDs) which capture diagnostic and predictive parameters for HF. In this work we explore how patients would respond to receiving data from an implanted device, using a fictitious scenario interview method with 24 older adults with HF. We applied an uncertainty management lens to better understand how patients face uncertain outcomes and integrate novel data into their decision making. The findings provide insight into how patients would engage and respond to a technology which provides an indicator of their HF status from an implanted device.
