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
