Sanitized Prototypes and Cargo Pants: Design and Evaluation of an Assistive Application for Dialysis Patients
Indiana University, Bloomington
Medical informatics, broadly defined as the integration of information
technology in health care, is revolutionizing all aspects of medicine from
electronic medical record systems to portable systems that assist clinicians
with medical decision-making and data entry. The human-computer interface
issues in medical informatics are particularly interesting because there are
often diverse user groups with different requirements for the same application
(i.e., clinicians and patients).
In this talk, I present Dietary Intake Monitoring Application (DIMA), a
patient-centered application designed to assist dialysis patients in monitoring
their dietary needs. Dialysis patients who do not comply with their dietary
restrictions run the risk of undergoing additional emergency dialysis,
hypertension, pulmonary edema, and death. Currently, patients try to remember
their fluid and sodium consumption or record it in a food diary. However, these
techniques fail in 80% of dialysis patients. To improve patients' ability to
record their fluid and sodium consumption, DIMA allows patients to record this
information using a personal digital assistant.
The varying levels of patient literacy and computing skills present a
particular challenge for the design of DIMA. Furthermore, user studies must be
conducted in dialysis wards, which are small, stressful, prohibit audio/video
recordings, and change rapidly without warning. In this talk I discuss methods
we developed to make patients more comfortable using DIMA in their everyday
lives, our framework for usability studies in non-traditional environments, and
interface design issues for people with varying literacy skills. I conclude the
talk by discussing future research directions in non-traditional environment
evaluation techniques for interdisciplinary projects.
