The purpose of this thesis is to scope the literature to understand how people who use injection drug (PWIDs) experience access to hepatitis C (HCV) testing and diagnosis. The design was a scoping review methodology, guided by Arksey and O’Malley, JBI, and PRISMA-ScR guidelines. A search was conducted through seven electronic databases using a peer-reviewed search strategy. Five studies were yielded through two-level screenings. The extracted data were synthesized using conventional data analysis and reported using tables and narrative summaries. Four categories were found: Awareness and Knowledge, Stigma, Healthcare Service, and Psychological Responses. The studies were conducted in Australia, UK, and US published between 2014 to 2018. A total of 19 participant characteristics were extracted to contextualize their experiences. The World Health Organization’s definition of accessibility should be defined through the guidance of the constructed truths of the individuals in the current context. The lack of demographic data and connection to client quotes further exacerbates the inequities among the population through overlooking their intragroup identities.
