Data linkage and computerised algorithmic coding to enhance individual clinical care for Aboriginal people living with chronic hepatitis B in the Northern Territory of Australia - Is it feasible?

By systematically, manually reviewing all available data we were able to allocate a HBV status to 91% of the study population.
