Colorado Care Tablet: the design of an interoperable Personal Health Application to help older adults with multimorbidity manage their medications.

Medication errors are common and cause serious health issues during care transitions, particularly for older adults with multiple chronic conditions. In this paper, we discuss the design and evaluation of the Colorado Care Tablet, a Personal Health Application (PHA) that helps older adults and their lay caregivers manage their medication regimes during care transitions. We created a PHA that older adults with limited computing experience could easily use by designing an application based on their real world artifacts and workflows.
