Health Within Reach
Background and Challenge
About half of the 2 million Americans living with chronic hepatitis B are of Asian ancestry, most of whom—or their parents—were born in countries where the infection is common. Another 3 million people in the U.S. have chronic hepatitis C, which can also lead to liver cancer. Despite these risks, many Asian Americans do not undergo screening—often because they are unaware of their higher risk and because their healthcare providers do not recommend testing.
SOM Tech partnered with a PCORI-funded research team, led by Dr. Nguyen, to explore whether a tablet-based app could encourage more Asian Americans to get screened for hepatitis B and C.
Engaging Patients and Community Partners
The team worked closely with community organizations, focus groups, and two patient advisory councils to ensure the intervention was culturally appropriate, age-inclusive, and fully patient-centered. The image above shows feedback on wireframes from researchers and community members. From color choices to button sizes and clear instructions, the team prioritized making prompts and language intuitive and easy to understand for all users.
Feedback on wireframes
Available in three languages
Key content delivered through videos
We facilitated design sessions with patient advisory groups, gathered feedback, and collaborated with the research team to help build the app. “It’s actually very hard to develop an app that’s informative, engaging, and concise,” says Dr. Tung Nguyen, Professor of Clinical Medicine at UCSF. Community and patient input was critical throughout development, guiding decisions on how to phrase questions to avoid misunderstandings and how to design touch-screen response buttons for optimal usability.
Personalized recommendations via an algorithm
Weight-range recommendation
We created clear, easy-to-follow, multilingual instructional forms for patients.
Outcomes and Impact
The project conducted a trial with 416 participants in the San Francisco Bay Area who had never undergone hepatitis screening. Testing concluded that a “Multi-lingual educational intervention using a mobile application in primary care clinics was well received by Asian American patients, enhanced patient-provider communication about HBV, and increased HBV screening. Technology can improve healthcare quality among Asian Americans”.
