The TransForm application transforms patient data input processes by replacing paper forms. The application runs on a tablet device such as an iPad, and offers cardiology staff a mobile, streamlined method for accessing and managing patient data.


Our interdisciplinary team of four HCI master students, working with GE Cardiovascular IT, has been tasked to design, develop, and evaluate a tool to improve cardiology workflow.

Research Overview

To arrive at our initial design ideas, we used contextual methods to investigate the problem space. The team traveled to four sites across the country to observe and interview cardiology staff members in their everyday work contexts. Specifically, we used contextual inquires to observe workflow - where permitted by HIPAA - directed storytelling to learn about past experiences, and visioning exercises to understand perceived workflow breakdowns and identify opportunities for improvement.

After our four site visits, and 39 interviews, we moved into the synthesis phase of our research plan. The primary goal of this phase was to organize and present our data in a format that helped us reach a shared understanding of the data, identify relationships and differences, spot breakdowns, and ultimately, draw out a set of high-level findings. To this end, we: created data models; transcribed our interviews; created “data buckets” with key insights, quotes and findings; and organized these buckets using affinity diagramming.

Insights and Findings

  1. Customization facilitates communication and processes 

  2. Streamlined data input is paramount to efficient and accurate work 

  3. System integration would save countless valuable resources 

  4. Accessible and portable information supports workflow mobility 

  5. Workflow flexibility increases staff satisfaction

 

Iterative Design

Create a tool to increase the efficiency and satisfaction of cardiology staff during the patient data input process.

The above statement guided our design phase and brought us to our final prototype. After honing in on our application concept, we carried out additional research to more fully understand the patient data input process. Next, we embarked on the design phase of our project, iteratively designing, building and testing our prototypes. We returned to many of the original research sites to test our ideas with real users. With user input, we continually refined our ideas and created a final, semi-functional prototype. In the end, we went through 3 big iterations, conducted 12 usability testing at 4 sites.

As the user experience lead of the team, my main responsibilities in this project include research planning, visual identity and experience design, refinement testings. I also created information diagrams [see below] and storyboards, produced a concept video to facilitate communication with clients at GE Healthcare.

Our tool, Transform app, meets these five design goals:

  • SATISFACTION: New technology is more fun to use
  • EFFICIENCY: Data synchronization improves accessibility
  • INTUITIVENESS: Standard UI components and interactions are easy to use
  • PATIENT DEDICATION: Patient-centric design puts patients first
  • ACCURACY: Error-checking capabilities and back-end data syncing improve accuracy

In addition, TransForm’s flexibility can support hospitals in complying with JCAHO regulations.

The final prototype was well received by GE Healthcare. Because of client confidentiality, our final design cannot be presented. Though, I'd be glad to speak more about it in person.
