Disease Risk Test

Discovery, Research, UX Design

Project Overview

Higi worked in partnership with the American Diabetes Association (ADA) and the American College of Cardiology (ACC) to combat the large number of Americans with undiagnosed  diabetes and heart disease by offering a free and convenient self-service assessment at Higi health stations.

I worked as lead UX designer to design and develop the Diabetes Risk Assessment and Heart Disease Risk Test. My role includes:  requirements gathering, stakeholder buy-in, design development, user testing, and launch.

Defining the Problem

Knowing one’s risk for diabetes is the first step diabetes management. Higi wanted a way to identify consumers who may be at risk for prediabetes so the team defined a problem statement: How do we support the consumer in understanding their diabetes risk and identifying next steps? 

“Eighty-four million American adults have prediabetes and 90% of them don’t know it”

Design iteration

Our solution to helping consumers understand their risk for diabetes and heart disease in an approachable, easy to use assessment. Based on the answers to health questions and biometric readings, the consumer receives a personalized risk score, actionable next steps and options to connect with personalized resources.

Action Nudge: 

Most users still perceive our kiosk as a “blood pressure” kiosk, so Risk Assessments were highlighted to encourage our users to engage with the kiosk beyond what they may perceive.

Question Transparency:

Provided contextual information for asking personal questions that contribute to disease risk score. This was added a direct response to user testing where user’s asked “How does impact my disease risk?”.

Personalized Risk Score 

Users are provided with a personalized score and additional information about the factors that contributed to their risk score.

Accessibility

To reach the widest audience possible with a single solution, we paid special attention to:

  • 4th grade reading level
  • Color contrast (AA)
  • Touch target size (AAA)
  • 2+ ways of displaying information (AA)

User Testing

When we encountered two solutions that could solve the problem but didn’t know which would resonate with users, we did some quick A/B testing to find out which option users prefer. The results revealed that users preferred and felt more confidant with one version, and uncovered an unknown usability issue that was quickly fixed.

Impact

  • As of 12/2019, over 75,000 Diabetes Risk Tests have been taken.
    • ~30,000 test received an a high risk reading.
  • Because of the success of the Diabetes Risk Assessment, new assessments are being added to the kiosk experience to help consumers better identify health risks.
