Hey hey! I’m Andrea Grigsby, a senior product designer passionate about improving patients’ health outcomes through user friendly digital health experiences
ResMed MaskSelector
A digital mask fitting mobile web app to remotely determine the type and size of CPAP mask that is most suitable for a patient's facial measurements.
The problem
Patients using the automatic face measuring portion of the tool met a large number of errors, resulting in an inability to successfully complete the scan.
The solution
To address this issue, I led a design discovery session with stakeholders and collaborated with a user researcher to identify baseline issues through an unmoderated user test. I then restructured the flow of the app in a way that is more intuitive for unfamiliar users and reworked instructions to ensure scanning success.
The impact
The total scan success rate increased to 94% as a result of these changes, a crucial step towards the app's global expansion outside of North America.
Peripherex
A revolutionary at-home vision field test that streamlines patients' optometry visits.
The problem
Optometry tests, especially the vision field exam, can be lengthy and tiring. Patients often feel out of control and overwhelmed during the process, which is compounded for those who must make repeated visits in a year.
The solution
I identified crucial points of improvement through conducting user tests with 5 participants. Based on the findings, I synthesized design suggestions to transform the patient experience by improving expectations, reducing barriers to completing the vision exam, and enhancing the user interface based on heuristics.
The impact
The improved user experience has demonstrated significant impact by supporting the FDA approval process of the tool.
MaskSelector Recommendation
The medical provider portion of MaskSelector (web app), recommending to clinicians the most suitable CPAP mask for patients.
The problem
The outdated recommendation system did not support the full range of available masks, resulting in a disjointed workflow and mistrust in the tool's accuracy among clinicians.
The solution
I collaborated with a technical writer to develop patient-friendly survey questions based on new, stakeholder-aligned recommendation logic. I conducted a heuristic analysis on the existing clinician portal, improved its information architecture, and incorporated system changes in an intuitive way. Finally, I led feedback sessions with major users to evaluate the changes' effectiveness before hand-off.
The impact
We anticipate that these changes will decrease the time clinicians need to select a patient's mask and improve overall accuracy by 20%.
