The Project
The goal of this project was to design a new workflow for a web-based electronic health record system; a workflow to support health care providers in managing their patients' vaccinations.
​
The initial release of this project received exceptional praise from clients in long-term care and physician office settings.

Understanding the Users' and Patients' Workflows
Discovery Phase
-
My Role: Sole UX designer in an agile development team
-
What I Did:
-
Led team's collaboration sessions with physician users​
-
Participated fully in gathering, clarifying, and analyzing requirements
-
Collaborated with product owner and tech leads on proposed workflow and navigation within the parent EMR
-
-
What I Learned:
-
The patient typically sees multiple members of the care team​
-
The physician would be our primary user, having more decisions to make about the patient's immunizations
-



Understanding Users' Mental Models
Discovery Phase
-
We learned:
-
Most health care providers use the CDC vaccination schedules and expected a similar data visualization
-
The CDC schedules are simple -- as long as the patient stays on schedule
-
Physicians reported that about 75% of their patients do not stay on schedule
-
-
We decided:
-
As a team, we decided that our product would have to support the "catching-up" scenarios
-

Variations by Patient's Age Group
Design Phase
-
Patients need different immunizations at different stages of their lives
-
Physicians expected the system to push what's important for the patient to the top​
-
​
-
For patients under 2 years, the CDC schedule shows their age in weeks or months
-
Physicians expected the age scale in our product to shift from weeks to months to years​
-

Example: 9 month old patient
Design Phase
-
I created mockups of several patient scenarios to prove out our analysis
​
-
The design focuses on the patient's age rather than the calendar year
-
The patient's current age defaults to the center of the chart - the highlighted column in the middle​
-

Example: 25 year old patient
Design Phase
For patients over 2 years, we faced a challenge with the age columns -- especially in the "catching-up" scenarios where a patient may need multiple doses within the year
​
We ended with a modified "fish-eye" zoom, expanding the current age column



Letting the User Interact with the Immunization Chart
Design Phase
-
Physicians wanted to be able to access more details as needed
-
I designed a series of "flyouts", allowing the user to click any icon and access information about that event
​
In the final stages of the product development, I collaborated intensely with the QA analysts to ensure thorough testing of the UI and workflow
