Summary
I redesigned the Promaxo MRI home screen to clearly surface patients scheduled for procedures that day, solving a common pain point in clinical workflows. By adding a “Today’s Patients” toggle and highlighting scheduled patients in green, I eliminated the need for clinicians to check personal notes. This saved an average of 4 minutes per procedure and increased professionalism in the operating room.
Context
Promaxo is a compact, office-based MRI machine used for real-time prostate imaging and biopsy. The product is deployed in clinical settings where speed and clarity are critical to success.
Problem
While shadowing clinical engineers during a self-initiated research sprint (after completing my initial project ahead of schedule), I noticed that before each procedure, they would check their phones to find out which patient was next.
Upon asking why, I learned the system’s patient list didn’t indicate who was scheduled for the day. Clinicians had to search manually by name, typing into a long, unsorted list, creating delays and making the workflow feel disorganized and unprofessional.
I proposed three design solutions.
Solution No. 1
Highlight today’s patients in green.
Solution No. 2
Only show today’s patients.
Solution No. 3
Today’s patients toggle.
Final Choice
The team agreed on a combination of 2 & 3, adding highlights on today’s patients and a toggle for increased ease of use.
Implementation Note
To support date-based logic in the patient list, I had the procedure date and time updated to be a required field in the patient creation workflow.
Results
After implementation, I saved 4 minutes of procedure prep time on average, and increased UX and operating room professionalism.
In hindsight…
In hindsight, I would have made all columns filterable by value, not just the patient procedure date, to give users more flexibility. The technical effort would have been minimal.
