Convergence: visualizing patient health history

About Convergence

A Windows 8.1/Microsoft Surface app that unites data from various EHR systems to give clinicians a comprehensive, user-friendly view of a patient's health history over time.

This was done at the UPMC TDC, an innovation group within the medical center.

Convergence never went live, and was shelved shortly after I left UPMC.

My role

For my first 6 months at the TDC, I worked on discovery, research, wireframing and prototyping, and validation.

The second 6 months were active development to get the app production-ready. I split my time between doing renderings (visual UI design) and discovery/UX/research. We did agile scrum, with 2-week sprints. I worked closely with a lead designer on the visual design, and with developers and QA on implementation details, including renderings and the overall user experience.

User research

I worked with 1 designer and 1-2 business analysts at any given time. Research was a regular part of our workloads. Some activities we'd do:

  • generative group whiteboarding
  • one-way-mirror user testing
  • paper prototyping
  • onsite validation and ethnographic observation at UPMC Presbyterian Hospital
  • SME validation sessions (several practicing doctors had offices at our building)

The pictured iterative brainstorming activity was one I facilitated. Several designers and BAs participated. We did 5- and 10-minute iterative sketching rounds to revisit our Timeline feature (a condensed view of a patient's medications, labs, vitals, and documents over time: several days, a week, a month, or a year). This provided a lot of qualitative value and fresh thinking that we could bring back to the broader team.

Sketches of timelines, charts, and grids on a wall, covered in sticky notes. They're the results of several quick rounds of brainstorming that I led our team in.

A couple of samples of our research synthesis docs, to share findings with our team in a fun and easily-scannable way.

While we collaborated on the synthesis, I led the synthesis sessions and other meetings with the other designers/BAs.

Note: I created this format and owned these documents. I took charge of editing/formatting/copywriting research notes, and did all the sketches and document layout/formatting.

Synthesis document, part 1. 5 columns of content: Clinical Process, Current Tools, Efficiency, Painting a Picture, Issues with Data. Each has chunks of text and sketches underneath that summarize our observations.

Synthesis document, part 2. A quick sketched column on the left showing our research and synthesis process, and then 2 columns of findings, one each for the Notes and Labs sections of the app.

Visualizing complex, dense medical information in a compact way.

Note: this is all false data.

Greyscale wireframes of the left-to-right flow of patient health data. Currently, Vitals is visible. Under the labs section, abnormal values are in red text. A toggle menu is selected, letting the user switch between pertinent labs for different medical specialties.

Vitals: highlighting abnormal values, and a way to toggle between different types of data in that dashboard panel.

Greyscale wireframe of the Labs view: a dense series of tables that show labs values over time. Abnormal values are in red. A menu to the upper left is open that lets the user switch between labs panels quickly.

Labs: quickly scannable table of lab values over time, highlighting abnormal values, with an easy way to switch between panels.

Greyscale wireframes of the Complete Blood Count view under Labs. There's a table to the left showing values over time, and a graph on the right charting the values in the table.

Labs – CBC: drilled-in view of what an individual lab result might look like.

Black-and-white wireframes of the Notes section. This is a series of tiles of notes per day. Each shows the note type, time, and department. One is open that shows a preview of the note content.

Notes: concept for time-based display of patient notes pertaining to different tests and caregiver interactions.

Renderings/UI Design

Samples of the visual/UI design work I did, with art direction and design patterns provided by a lead designer.

Polished UI design - with identifying info redacted - of the timeline, or top-level, view of the app, focusing on the Vitals data.

Vitals: timeline/top-level view.

Polished UI design - with identifying info redacted - of the Documents view of the app. Document text labels are color-coded based on status.

Documents: timeline/top-level view.

Polished UI design of the doctor's view, where they can choose from their various patient lists to the left. Each list displays a tile view of the patients in that list to the right.

Doctor's view: seeing a list of patient lists and being able to select the apt one. This mockup just reused one patient name instead of demonstrating a list of different patients.

Vitals: drilled-in view to see both a tabular view and a chart view of multiple lines of data over time.
