Usability Test Executive Summary
Healthcare is undergoing a massive transformation to information technology and it is critical that people with disabilities be included in the design of new systems. Our project demonstrates a comprehensive user-centered approach, specifically with people with disabilities, in designing an electronic personal health record (PHR) that is not only accessible, but also usable and highly functional.
The final product of our project is a set of interactive PHR prototypes. The prototypes were developed from a user-centered process with participation from nearly 200 people with disabilities. User-centered design methods included:
- Semi structured interviews (16 participants)
- End user survey (150 participants)
- Review of three existing PHR/patient portal systems for accessibility, usability and functionality (expert review)
- Formative/iterative user testing (10 participants)
- Summative usability testing (16 participants)
Usability Test Overview
This overview summarizes the results of the summative usability testing. (The semi-structured interviews, end user survey, and expert review are described in the Initial Findings report.) 16 people with disabilities participated in a usability test of the PHR prototypes. The testing was based on performing 5 task based scenarios:
- User preferences
- Medical equipment
- Care Plan
Usability testing verified that the prototype PHR demonstrates requirements identified by consumers who participated in the project, and showcases accessible and usable functionality. Participants found the prototype PHR accessible and easy to use. It presented tasks important to their healthcare, with useful features and information. All participants agreed the system would be useful in managing their own health care, and several commented that they would use to it manage the care of a family member.
