843Hepatitis C in South Australia and Northern Territory: a population-based linkage study

Abstract

Abstract Background In Australia, the notification rate for hepatitis C is five times greater among Aboriginal and Torres Strait Islander peoples than nonIndigenous populations. Infection with Hepatitis C virus is associated with increased morbidity, mortality and health-related costs. However simple, tolerable and short-duration HCV therapies with extremely high efficacy are available. Methods Overall, this project aims to identify inequities in hepatitis C healthcare for Aboriginal and Torres Strait Islander peoples across South Australia (SA) and Northern Territory (NT). By using 19 routinely collected health administration datasets, we will evaluate hepatitis C diagnoses, treatment uptake, and treatment outcomes, with focus on identifying patterns in healthcare access among Aboriginal and Torres Strait Islander people in SA since 1992 or in NT since 1999 using probabilistic data linkage methodology in a secured online environment. Results The study population includes all hepatitis C notifications recorded in SA and NT, totaling more than 25,000 cases. Preliminary findings will be reported including incidence of hospitalisation, mortality, and morbidity by Aboriginal and Torres Strait Islander status. Conclusions Now that highly effective direct acting anti-viral treatments are available, it is crucial to ensure key affected populations, including Aboriginal and Torres Strait Islander people, have access to these novel biomedical approaches. Key messages This project is of national importance to address hepatitis C related morbidity and mortality in Australia, particularly among Aboriginal and Torres Strait Islander peoples. Findings will underpin future policy to reduce the burden of hepatitis C across SA and NT populations.
