Verto

Background

Distinguishing between vestibular neuritis and stroke in a timely manner is critical. Through an agile design process, we worked with an early stage startup client, VertigoMetric Diagnostics, to create a digital interface and training guide for an emerging emergency room (ER) retinal diagnostic technology.

User Research

Currently, when patients arrive in the ER with dizziness, it is difficult to differentiate between stroke, a life threatening condition, and vestibular neuritis, a non-life threatening condition.

To understand the stakeholders who would be affected by Verto and implement a solution that fits into the ER workflow, we recruited and interviewed a variety of healthcare providers including physicians, nurses, medical students, and imaging technicians.

Research Findings
  1. The ER is a complex, intense, and emotional environment.
  2. The interface must be intuitive, as the number of patients who present solely with dizziness will likely not warrant a dedicated technician.
  3. The interface must provide a quantitative result to assist the healthcare professional in determining the next steps for care.
Prototyping and Testing

We first created low fidelity paper prototypes and wireframes to understand the high level functions required. In our later sprints, we moved toward a higher fidelity, interactive paper prototype and then a digital interface.

With each iteration, we tested with various medical professionals such as Emergency Room physicians, nurses, and imaging technicians to incorporate the needs of our stakeholders. Our prototypes also evolved as business needs and technological capabilities around a physical device were uncovered.

Final Deliverables

At the end of 10 weeks, we presented a video that served as a walkthrough of our digital interface and explained the basic principles of the technology. In our presentation, we emphasized how parts of our interface incorporated features from our insights such as: familiarity in the login page, intuitiveness through automated calculations, and guidance for next steps of patient care.
