简要总结
Liver cancer and hepatitis B are health disparities for Asian Americans, and hepatitis C is a rising problem. Little is known about how to improve the quality of health care Asian Americans receive for viral hepatitis. Technology, specifically mobile applications, can provide a flexible and efficient way to address these challenges. This project seeks to develop, implement, and test an intervention to increase hepatitis B and C screening for Asian Americans in 2 healthcare systems in San Francisco.
The research team will develop, implement, and evaluate the efficacy of an interactive, patient- centered mobile app for use on a tablet computer to increase hepatitis B and C screening among unscreened Asian Americans age 18 and older. The team will use their experience in health promotion to develop the intervention by working with patients, community leaders and advocates, clinical staff, healthcare providers, and healthcare system administrators from a county safety net system and an academic primary care practice in the San Francisco Bay Area. The mobile application will include video clips with a physician (Video Doctor) addressing patient concerns regarding hepatitis B and C screening in the patient's preferred language, English, Chinese, or Vietnamese. A patient who has not been screened for hepatitis B will answer questions about his or her characteristics and preferences using the mobile application. The mobile application will then show 30-60 seconds video clips with messages that address the patient's responses related to hepatitis B screening and that are delivered by an actor playing a physician. Those who are born between 1945 and 1965 also receive messages about hepatitis C screening. At the end, the tablet computer will generate a provider alert to let the treating provider know what the patient's preferences are regarding testing for viral hepatitis.
Once developed, the intervention will then be used in combination with a physician panel notification and tested against physician panel notification only in a randomized controlled trial to see which approach is better in increasing the rate of hepatitis B and C screening. The team will also work with the 2 healthcare system to ensure that the interventions will be practical and easily adopted once the study is over. The findings of this project will greatly expand understanding about how to use technology- based interventions to improve quality of healthcare in diverse patient populations.

结局指标
主要结局
EHR-documented hepatitis B surface antigen (HBsAg) test
时间窗: 3 months
The main outcome measure is an EHR-documented hepatitis B surface antigen (HBsAg) test at 3 months post-intervention. We chose screening for hepatitis B because, among adults, particularly immigrants or descendants of immigrants, it is the most important first step in the control of viral hepatitis B and lack of screening remains a significant problem. While many young adult Asian Americans born in the U.S. or who immigrated at a young age may have been vaccinated for hepatitis B as a child or prior to entering college, pre-vaccination testing may not have been done. Given the high rates of infection in their parents and the possibility of vertical transmission, all Asian Americans should be tested for chronic hepatitis B using the HBsAg test. All screening outcomes (test receipt) as well as test ordering by the healthcare providers will be collected from the medical record through the EHRs at 3-month post-intervention.
