The Asian Liver Center conducts collaborative research to identify the gaps in hepatitis B knowledge, healthcare providers’ training, preventive practices, screening and chronic hepatitis B care continuum in the United States and in countries with a high prevalence of chronic hepatitis B infection. We also conduct modeling research to estimate the population level health and economic impact if new national policies are implemented to increase hepatitis B prevention, screening and treatment. An example is research in collaboration with the Stanford Prevention Policy Modeling Lab and US CDC that provided the cost-effectiveness evidence for the 2023 CDC recommendation to screen every adult in the United States at least once in their lifetime for hepatitis B.
In collaboration with the World Health Organization, we have also developed Hep B Calculator, a free mathematical research tool to help countries determine the economic and population health impact of chronic hepatitis B treatment.
