Liver cancer and hepatitis B are major health disparities for Asian Americans, while hepatitis C is a rising problem. Little is known about how to improve the quality of health care Asian Americans receive in general and for viral hepatitis in particular. Technology, specifically mobile applications, potentially can provide a flexible and efficient way to address these challenges. This proposed project seeks to develop, implement, and test an intervention to increase hepatitis B and C screening for Asian Americans in 2 healthcare systems in the San Francisco Bay Area.
