    P2HR, a personalized condition-driven person health record
    (2017) King, Zachary; Ben-Miled, Zina
    Health IT has recently seen a significant progress with the nationwide migration of several hospitals from legacy patient records to standardized Electronic Health Record (EHR) and the establishment of various Health Information Exchanges that facilitate access to patient health data across multiple networks. While this progress is a major enabler of improved health care services, it is unable to deliver the continuum of the patient's current and historical health data needed by emerging trends in medicine. Fields such as precision and preventive medicine require longitudinal health data in addition to complementary data such as social, demographic and family history. This thesis introduces a person health record (PHR) which overcomes the above gap through a personalized framework that organizes health data according to the patient’s disease condition. The proposed personalized person health record (P2HR) represents a departure from the standardized one-size-fits-all model of currently available PHRs. It also relies on a hybrid peer-to-peer model to facilitate patient provider communication. One of the core challenges of the proposed framework is the mapping between the event-based data model used by current EHRs and PHRs and the proposed condition-based data model. Effectively mapping symptoms and measurements to disease conditions is challenging given that each symptom or measurement may be associated with multiple disease conditions. To alleviate these problems the proposed framework allows users and their health care providers to establish the relationships between events and disease conditions on a case-by-case basis. This organization provides both the patient and the provider with a better view of each disease condition and its progression.

    Promoting common ground in a clinical setting: the impact of designing for the secondary user experience
    (2016-07-27) Tunnell, Harry D., IV; Bolchini, Davide; Faiola, Anthony; Doebbeling, Bradley; Haggstrom, David
    Primary users can create a user experience (UX) for others—secondary users— when interacting with a system in public. Common ground occurs when people have certain knowledge in common and each knows that they have this shared understanding. This research investigates how designing for a secondary UX improves common ground during a patient-provider first encounter. During formative work, patients and providers participated in telephonic interviews and answered online questionnaires so that their respective information requirements for clinical encounters could be understood. The outcome of the formative work was a smartphone application prototype to be used as the treatment in an experimental study. In a mixed methods study, with a patient role-player using the prototype during a simulated clinical encounter with 12 providers, the impact of the prototype upon secondary user satisfaction and common ground was assessed. The main finding was that the prototype was capable of positively impacting secondary user satisfaction and facilitating common ground in certain instances. Combining the notions of human-computer interaction design, common ground, and smartphone technology improved the efficiency and effectiveness of providers during the simulated face-to-face first encounter with a patient. The investigation substantiated the notion that properly designed interactive systems have the potential to provide a satisfactory secondary UX and facilitate common ground.
