Patient Portal Use And Patient Education Materials Access Among Mississippi Adult Residents, Anna K. Swann

Dissertations

Patient education plays a vital role in improving the health outcomes of patients with chronic diseases and helps prevent illness in otherwise healthy individuals. Patient portals allow patients to access their EHRs, communicate with their healthcare providers, and access patient education materials. Despite the potential for patient portals and education materials to improve health outcomes, many barriers prevent patients from utilizing them. Uneducated patients are more likely to participate in risky health behaviors, which leads to poor health outcomes. Poor health outcomes lead to higher medical costs. Mississippi has a high rate of chronic diseases. Suppose the barriers to patient …

Visualization Of Cardiac Implantable Electronic Device Data For Older Adults Using Participatory Design., Ryan Ahmed, Tammy Toscos Phd, Romisa Rohani Ghahari, Richard J Holden, Elizabeth Martin, Shauna Wagner, Carly Daley, Amanda Coupe, Michael Mirro Md

Health Services and Informatics Research

Patients with heart failure (HF) are commonly implanted with cardiac resynchronization therapy (CRT) devices as part of their treatment. Presently, they cannot directly access the remote monitoring (RM) data generated from these devices, representing a missed opportunity for increased knowledge and engagement in care. However, electronic health data sharing can create information overload issues for both clinicians and patients, and some older patients may not be comfortable using the technology (i.e., computers and smartphones) necessary to access this data. To mitigate these problems, patients can be directly involved in the creation of data visualization tailored to their preferences and needs, …
