Current Research Projects:
Hepatitis Education Canada
The project investigates factors influencing attendance for hepatitis C care. Based on research findings, the program develops culturally and linguistically appropriate hepatitis C education resources for the population, hepatitis patients and health care providers. It covers topics such as prevention, testing, care and support, treatment and living with hepatitis. Resources include e-learning course, print material, videos, and a website (http://hepatitiseducation.ca ) that bring everything together with an easily accessible navigation hub on the front page for various cultural and linguistic groups.
