The Peace Corps needs a web based user interface framework for an electronic medical record system (EMR) that includes intuitive navigation, patient data presentation, clinical form layouts, and aesthetics. The focus was on the dashboard, patient summary page, and patient encounter form.
A redesign of the three sections that will reduce the number of clicks and time needed to enter and access information within PCMEDICS. The new design will include features for tracking unfinished work, universal search options, and customizable content boxes to allow for different needs of the several users accessing the system.
As a part of a three person team, my role was comprised of leading the interface re-design, wireframing, user testing the prototype through several iterations, and designing the high fidelity mockups of each page. In addition, I collaborated with my team members to provide preliminary user research and competitive analysis.
Background & Resources
When we first spoke with Peace Corps, the meeting gave us an understanding of how to apply our knowledge of user experience design to their existing, and very complex, EMR. My team and I broke down the current system with our client to get a top level familiarity with the system.
"Doctors are busy. They're used to seeing a lot of details. The information they are accessing needs to be organized in an intuitive, easy-to-understand way"

They provided screenshots of the three pages they wanted us to work on and walked us through the current interactions and user types. This information was invaluable in understanding their needs and yielded a discussion on how to improve the current system.
The dashboard is dominated by the calendar and message center. The features are little used, yet take up the majority of the page.
The left navigation bar, which includes items frequently used, is cramped and hard to navigate. Search is often used, yet is buried at the bottom of the page.
Patient Summary Page
The patient summary page is dominated by demographic information that users of the system said was of little value given the prominent placement.
More useful features like medication, allergies and problems get less prominent placement and the frames make it difficult to find important information.
Patient Encounter Form
The patient encounter form is divided in to 4 sections that medical officers have to continuously jump back and forth between while meeting with patients.
It is crucial that the medical officers are able to reference the patient's medical history, current medication, and allergies at all times while completing this form, making it difficult to stay focused.
In order to gain a broader understanding of the PCMEDICS interface, I conducted interviews with medical officers who interact with the current system on a daily basis. Though tasked with contacting, scheduling, and conducting interviews with a geographically diverse group of users proved challenging, the insights were invaluable.
"The search bar is at the bottom corner. I'm not sure that makes the most sense given it's level of usage."

Preceding user interviews, the unwieldiness of the system through a lack of coherent navigation compounded by confusing verbiage proved to be crucial problems. With the help of our client, we identified a list of major pain points to narrow the scope of our design work:
- The landing page was not useful, and some in the field would bypass it entirely
- Trying to e-sign a form was an exercise in futility that required jumping back and forth from the beginning to end of the form
- In many cases, routine work in PCMEDICS requires continual re-sizing of viewing panes to access information
- Verbiage is not consistent throughout the site which causes confusion
- The volunteer summary page devoted the most real estate to the least useful information (unchanging demographic information)
Sketching & Wireframing
Using agile methodologies, I was able to lead the team in initial wireframes based off of the feedback given by Peace Corps staff every step of the way. I wanted to focus on reorganizing the current system to fall in line with established design trends (i.e. search bar location, profile photo) and provide a clear system hierarchy through scale.
- Search bar prominently placed
- Drawing attention to alerts and new messages
- Quick view calendar for day, week, or month
- Agenda and task tracking
Patient Summary Page
- Emphasis on static medication, allergy, and lab information
- Profile photo to ensure patient recognition
- Detailed patient history list with filtering options
- Reduced demographic information
Patient encounter form
- Drop down boxes with frequently used information
- Collapsable sections for quick navigation
- Quick links to add additional forms
- Tabs within dense sections to avoid scrolling up and down
ITERATIONS & TESTING
Expanding the Design
After coming to conclusions about what was working and what wasn’t, I mocked up a low fidelity digital prototype to test. These iterations expanded past the scope of our redesign of the current pages which included a feature set developed in order to fill the holes in the system.
Through testing we found that there was a different priority level for information based on the user accessing the network (medical officer vs headquarters staff), and that we needed to design for customization.

The final result was one that was very much anticipated and very well informed. Our clients were extremely satisfied with the problems we solved and the feature set we added which included:
Dual Time Zone • Personalized User Login• Customizable Dashboard • Quick Glance Calendar • In Progress • Tasks • Resizable Content
I built the final prototype using Sketch and Keynote. The new constraints gave us a shortened timeline so I needed to use tools that allowed me to quickly design at a high level and add the interactions needed to demonstrate functionality.
