Patient/System Research

Health Literacy, Medication Burden and Self Care Behaviors in Patients with Heart Failure Across Multiple Care Settings

  • Primary Investigator: Kimberly Plake, Ph.D., RPh, Pharmacy Practice
  • Faculty: Karen Yehle, Ph.D., MS, CNS-BC, Nursing
  • Students: Aleda M. Hess, PharmD, Pharmacy Practice and Gerontology
  • Overview: Heart failure is a chronic illness which requires health-related skills, such as monitoring and appropriately taking medications. Inadequate health literacy on the part of the patient or the caregiver may lead to poor self-care or increased medication burdens. This research team is working to determine the impact of health literacy on self-care ability and medication administration among heart failure patients.

Health Literacy in Underserved, Pre-Diabetic Populations

  • Primary Investigator: Jakob Jensen, Ph.D., Communication and Oncological Sciences Center
  • Students: Graham Bodie, Communication
  • Healthcare Partner:
    Purdue Extension
    Community Health Network
  • Overview: Patient-centered healthcare delivery is increasingly common, but many patients have insufficient skills to manage their own health. This study seeks to address this problem by creating and validating instruments that measure health skills (e.g., health literacy) necessary for patient-centered care. This research targets underserved, pre-diabetic populations in four Indiana counties - Lake, Marion, Howard and Tippecanoe.

Self-Care and Health Literacy in Telehealth and Traditional Home Health Patients with Heart Failure

  • Primary Investigator: Karen Yehle, Ph.D., MS, CNS-BC, Nursing
  • Faculty: Kimberly Plake, Ph.D., RPh, Pharmacy Practice
  • Students: Megan Martin, Nursing
  • Healthcare Partner: Community Health Network
  • Overview: Heart failure is a chronic illness that requires daily monitoring. Delivering data from the patient to the healthcare provider assists the provide in caring for the patient. This one-way delivery of information does not necessarily result in patient behavior changes necessary to optimize health outcomes. A main goal of this project is to compare the impact of telehealth vs. tradition home health on health literacy, self-care ability and health outcomes among patients with heart failure.

Care Services Research

  • Overview: New technologies, including web, elearning, and social networking technologies can play a role in bridging patients and providers in meaningful and scaleable ways. This research team is looking at how patient self-care ability, health literacy, and related factors are influenced by information and media consumption and how healthcare providers can leverage patient-oriented information systems to assess patient risk and define appropriate interventions.

Patient Scheduling

  • Principal Investigator: Mark Lawley, Ph.D., Biomedical Engineering
  • Faculty:
    Kumar Muthuraman, Industrial Engineering, University of Texas
    Laura Sands, Nursing
    Deanna Willis, Quality and Medical Management, Indiana University Medical Group
  • Students: Joanne Daggy, Statistics
  • Healthcare Partners: Wishard, Indiana University Medical Group
  • Overview: Clinical managers and physicians are usually quick to identify inadequate patient scheduling as a major source of operational inefficiency and patient dissatisfaction. The expertise to implement advanced scheduling methods does not exist in most clinics, and clinical information technologies do not easily support data and computational needs. This project utilizes engineering and statistical analysis to optimize patient satisfaction, clinic access, waiting times and clinic efficiency.
