Introduction Despite the availability of effective, subsidised hepatitis B treatment, linkage to care and treatment rates remain very low globally. In Australia, specially trained primary care physicians (general practitioner, GPs) can prescribe hepatitis B treatment, however, most hepatitis B care occurs in specialist clinics. Increasing hepatitis B management by GPs in primary care clinics is essential to achieve national hepatitis B linkage to care and treatment targets by 2030. This pilot study determines the feasibility, acceptability and effectiveness of Simply B, a novel GP hepatitis B e-support package designed to increase hepatitis B management by GPs in primary care clinics. Methods and analysis This study will be conducted in three parts: Part A: A prospective open-label pilot intervention study, comparing the proportion of people with hepatitis B who are managed by their GP in primary care clinics before, 12 months and 24 months after implementation of the Simply B electronic hepatitis B support package. Part B: A nested qualitative health services feasibility study using semistructured interviews and thematic analysis Part C: Cost-effectiveness analysis. Ethics and dissemination This study has received ethics approval by St Vincent’s Hospital. Data management and analysis will be centralised through the Department of Gastroenterology, St Vincent’s Hospital. Trial registration number NCT05614466.

BACKGROUND:Pregnant women are a priority group for hepatitis B testing. Guideline-based care during antenatal and post-partum periods aims to prevent mother-to-child transmission of hepatitis B virus and lower the risk of liver complications in mothers. This qualitative study explored knowledge of hepatitis B and experiences of hepatitis B related care among pregnant women and mothers.METHODS:Semi-structured interviews were conducted with thirteen women with hepatitis B who were attending antenatal or post-partum hepatitis B care. The interviews were thematically analysed to assess knowledge and understanding of hepatitis B. Participants were recruited from specialist clinics in metropolitan Melbourne between August 2019 and May 2020.RESULTS:Four major themes were identified from interviews: (1) knowledge and understanding of hepatitis B, (2) treatment pathways, (3) accessing hepatitis B related care, and (4) disclosing status to friends. Most participants displayed an understanding of hepatitis B transmission, including mother to child transmission. The main motivator of post-partum attendance was reassurance gained concerning their child's health. Sources of hepatitis B information included doctors, online information and family. Participants identified parents and siblings as sources of support and reported an unwillingness to disclose hepatitis B status to friends.CONCLUSIONS:Women attending antenatal or post-partum care reported having overall positive experiences, particularly regarding reassurance of their child's health, but displayed misconceptions around horizontal transmission. Knowledge gained from these results can contribute to the development of targeted models of care for pregnant women and mothers with young children to ensure their successful linkage to care.

Conclusion: Dry blood sampling can identify promising biomarker candidates that could improve HCC time-to-and stage-at-diagnosis.While our findings will be confirmed in a prospective study, focusing on age and risk factor stratification, we aim to translate our findings into an easy-to-use, low-cost population screening tool for HCC.
