Developing, testing and disseminating best practices for eliminating health disparities associated with chronic hepatitis B infection.
The HBF public health team conducts research and develops interventions locally, nationally and internationally. In Philadelphia, HBF leads a community-based participatory research program, including a 75-organizational member coalition. Together, the team has developed a multi-platform, citywide effort to improve rates of hepatitis B screening, vaccination and linkage to care for highly affected communities, with a focus on Asian Americans. HBF also studies the epidemiological landscape of chronic infection in Philadelphia, including identifying factors associated with infection and immunity, so they can tailor interventions to be more effective and efficient. Nationally, HBF co-manage’s Hep B United, a nationwide coalition that supports and leverages the success of local community coalitions across the U.S. to increase hepatitis B awareness, screening, vaccination and linkage to care for all Americans, but in particular, for high-risk Asian Americans and Pacific Islanders who are disproportionately impacted. The HBF public health team works with the Centers for Disease Control and Prevention (CDC) to develop a multi-year program that offers capacity building, training and technical assistance so that all Hep B United partner coalitions have the ability to offer screening, vaccination, education and patient navigation in their communities. HBF has also developed #justB, a multi-lingual storytelling campaign to improve awareness and reduce stigma around hepatitis B. The team uses evidence-based strategies to train and engage storytellers and evaluates the program at multiple levels (including message testing) to assess impact. Internationally, we partner on programs in Ho-Chi Minh City, Vietnam and Accra, Ghana, and direct a multi-year program in Haimen City, China. The program has included public awareness campaigns, provider education, free screening and linkage to care, and a program to reduce perinatal transmission of hepatitis B.
Through the stated programs, the HBF public health team conducts quantitative and qualitative data collection and analysis; survey development and testing; community-based participatory research (CBPR); health disparities research; patient engagement; program evaluation; coalition building and maintenance; and public health model building.
