    Wallace, J ; Richmond, J ; Howell, J ; Hajarizadeh, B ; Power, J ; Treloar, C ; Revill, PA ; Cowie, B ; Wang, S ; Stoove, M ; Pedrana, A ; Hellard, M (MDPI, 2022-11)
    Hepatitis B is a significant global health issue where the 296 million people estimated to live with the infection risk liver disease or cancer without clinical intervention. The World Health Organization has committed to eliminating viral hepatitis as a public health threat by 2030, with future curative hepatitis B interventions potentially revolutionizing public health responses to hepatitis B, and being essential for viral hepatitis elimination. Understanding the social and public health implications of any cure is imperative for its successful implementation. This exploratory research, using semi-structured qualitative interviews with a broad range of professional stakeholders identifies the public health elements needed to ensure that a hepatitis B cure can be accessed by all people with hepatitis B. Issues highlighted by the experience of hepatitis C cure access include preparatory work to reorientate policy settings, develop resourcing options, and the appropriateness of health service delivery models. While the form and complexity of curative hepatitis B interventions are to be determined, addressing current disparities in cascade of care figures is imperative with implementation models needing to respond to the cultural contexts, social implications, and health needs of people with hepatitis B, with cure endpoints and discourse being contested.

    Xiao, Y ; van Gemert, C ; Howell, J ; Wallace, J ; Richmond, J ; Adamson, E ; Thompson, A ; Hellard, M (BMC, 2022-06-02)
    BACKGROUND: In Australia, only 22% of people with chronic hepatitis B (CHB) are clinically managed; and a national effort is engaging primary care workforce in providing CHB-related care. This study explored CHB-related knowledge, attitudes, barriers and support needs of general practitioners (GPs). METHODS: A survey was sent to a random sample of 1,000 Australian GPs in April- October 2018; 134 of 978 eligible GPs completed the questionnaire (14%). RESULTS: Respondents had high knowledge of at-risk populations (> 79%) and hepatitis B serology (82%), and most saw hepatitis B testing and monitoring as part of their work (95% and 86%, respectively). However, the survey revealed low knowledge, awareness and intention with respect to hepatitis B treatment: 23% correctly understood treatment initiation; 40% were aware that treatment for CHB could be dispensed in the community; 23% agreed that prescribing was part of their work. Lack of time was considered the greatest barrier (38%) and clear guidelines was the most important facilitator to providing care (72%). CONCLUSION: Interventions are needed to generate interest and skills to provide CHB-related care by GPs.

    Randomised controlled trial of active case management to link hepatitis C notifications to treatment in Tasmania, Australia: a study protocol
    Marukutira, T ; Moore, KP ; Hellard, M ; Richmond, J ; Turner, K ; Pedrana, AE ; Melody, S ; Johnston, FH ; Owen, L ; Van den Boom, W ; Scott, N ; Thompson, A ; Iser, D ; Spelman, T ; Veitch, M ; Stoove, MA ; Doyle, J (BMJ PUBLISHING GROUP, 2022-03)
    INTRODUCTION: By subsidising access to direct acting antivirals (DAAs) for all people living with hepatitis C (HCV) in 2016, Australia is positioned to eliminate HCV as a public health threat. However, uptake of DAAs has declined over recent years and new initiatives are needed to engage people living with HCV in care. Active follow-up of HCV notifications by the health department to the notifying general practitioner (GP) may increase treatment uptake. In this study, we explore the impact of using hepatitis C notifications systems to engage diagnosing GPs and improve patient access to treatment. METHODS AND ANALYSIS: This study is a randomised controlled trial comparing enhanced case management of HCV notifications with standard of care. The intervention includes phone calls from a department of health (DoH) specialist HCV nurse to notifying GPs and offering HCV management support. The level of support requested by the GP was graded in complexity: level 1: HCV information only; level 2: follow-up testing advice; level 3: prescription support including linkage to specialist clinicians and level 4: direct patient contact. The study population includes all GPs in Tasmania who notified HCV diagnosis to the DoH between September 2020 and December 2021. The primary outcome is proportion of HCV cases who initiate DAAs after 12 weeks of HCV notification to the health department. Secondary outcomes are proportion of HCV notifications that complete HCV RNA testing, treatment workup and treatment completion. Multiple logistic regression modelling will explore factors associated with the primary and secondary outcomes. The sample size required to detect a significant difference for the primary outcome is 85 GPs in each arm with a two-sided alpha of 0.05% and 80% power. ETHICS AND DISSEMINATION: The study was approved by University of Tasmania's Human Research Ethics Committee (Protocol ID: 18418) on 17 December 2019. Results of the project will be presented in scientific meetings and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04510246. TRIAL PROGRESSION: The study commenced recruitment in September 2020 and end of study expected December 2021.

    Understanding how to live with hepatitis B: a qualitative investigation of peer advice for Chinese people living with hepatitis B in Australia
    Wallace, J ; Xiao, Y ; Howell, J ; Thompson, A ; Allard, N ; Adamson, E ; Richmond, J ; Hajarizadeh, B ; Eagle, M ; Doyle, J ; Hellard, M (BMC, 2022-03-18)
    BACKGROUND: Hepatitis B is a chronic viral infection, a leading cause of primary liver cancer and identified as a major public health priority by the World Health Organization. Despite a high proportion of people in Australia who have been diagnosed with hepatitis B, significant gaps remain in health care access and in accurate knowledge about hepatitis B. Most people with hepatitis B in Australia were born in China, where the infection has an intergenerational impact with significant social implications resulting from the infection. Understanding how people of Chinese ethnicity with hepatitis B understand and respond to hepatitis B is imperative for reducing morbidity, mortality, and the personal and social impact of the infection. METHODS: Qualitative semi-structured interviews with people with hepatitis B of Chinese ethnicity recruited through a specialist service identified the advice people with hepatitis B thought was important enough to inform the experience of people newly diagnosed with hepatitis B. A thematic analysis of the data privileged the lived experience of participants and their personal, rather than clinical, explanations of the virus. RESULTS: Hepatitis B infection had psychological and physical consequences that were informed by cultural norms, and to which people had responded to with significant behavioural change. Despite this cohort being engaged with specialist clinical services with access to the most recent, comprehensive, and expert information, much of the advice people with hepatitis B identified as important for living with hepatitis B was not based on biomedical understandings. Key suggestions from people with hepatitis B were to form sustainable clinical relationships, develop emotional resilience, make dietary changes, regulate energy, and issues related to disclosure. CONCLUSIONS: The study highlights conflicts between biomedical and public health explanations and the lived experience of hepatitis B among people of Chinese ethnicity in Australia. Beliefs about hepatitis B are embedded within cultural understandings of health that can conflict with bio-medical explanations of the infection. Acknowledging these perspectives provides for insightful communication between health services and their clients, and the development of nuanced models of care informed by the experience of people with hepatitis B.

    The personal and social impact of chronic hepatitis B: A qualitative study of Vietnamese and Chinese participants in Australia
    Le Gautier, R ; Wallace, J ; Richmond, JA ; Pitts, M (WILEY, 2021-09)
    This study explores the lived experiences of chronic hepatitis B (CHB) among Vietnamese and Chinese-born people living in Melbourne, Australia. The aims of this study were to investigate the personal and social implications of CHB, and the extent to which these implications, including experiences of stigma and marginalisation, affect individuals' overall quality of life. This study is based on individual semi-structured interviews with 37 Vietnamese and Chinese people with CHB in Australia (n = 22 and n = 15 respectively). The interviews were conducted between February 2015 and November 2016. Electronically recorded interviews of up to 1.5 hr were conducted, translated where necessary and transcribed verbatim. Transcripts were coded using NVivo, with coding themes guided by the principles of thematic analysis. Fundamental to most participants' accounts was the experience of living in constant fear of stigma and marginalisation, which participants unanimously attributed to prevailing misconceptions about hepatitis B-related transmission routes and disease outcomes. The accompanying experiences of social isolation-whether imposed upon themselves or by others-brought on additional feelings of shame and emotional pain, which had a profound impact on participants' overall quality of life. By exploring participants' lived experiences of hepatitis B, it became clear that concerns about the clinical implications related to hepatitis B as a biomedical infection make up only a small part of their experiences. Of particular significance were personal and social concerns around transmission, disclosure as well as the impact of stigma and marginalisation on participants and their families. Adopting a comprehensive multi-pronged response to tackle the multitude of complexities surrounding this infection among key affected communities will be more effective than just recognising the physical experience of the infection.

    Addressing pregnancy-related concerns in women with inflammatory bowel disease: Insights from the patient's perspective
    Flanagan, EK ; Richmond, J ; Thompson, AJ ; Desmond, P ; Bell, SJ (WILEY, 2021-01)
    BACKGROUND AND AIM: Therapeutic options for inflammatory bowel disease (IBD) have expanded, as has the use of IBD medications in women during the reproductive period. However, no qualitative data exist that examine the pregnancy-related concerns of women with IBD in the current era of widespread immunomodulator and biologic use. Hence, we aimed to explore in detail the impact of IBD on pregnancy from the patient's perspective. METHODS: This qualitative study used semistructured interviews to explore participants' experiences regarding IBD and pregnancy until no new themes emerged. Key themes were identified using thematic analysis. RESULTS: Fifteen women with IBD were interviewed. The majority of participants reported lingering concerns regarding their IBD medications, despite advice from their gastroenterologist that the drugs were considered safe in pregnancy. Participants more often reported medication-related fears, such as potential negative effects on their child's immune system, than concerns regarding the effect of the disease itself on their pregnancy outcomes. A common theme was a perceived lack of knowledge among non-IBD clinicians regarding IBD medications during pregnancy, which augmented pre-existing anxiety. CONCLUSIONS: This study is the first of its kind to provide an in-depth assessment of female patients' perspectives of IBD in relation to conception, pregnancy, and caring for offspring. In particular, this research characterizes the unique fears and persisting anxieties regarding IBD medications in pregnancy. The study has unearthed important insights into the specific concerns and support needs of women with IBD in order to facilitate nonjudgmental counseling designed around patient concerns and beliefs.

    'Teach-back' is a simple communication tool that improves disease knowledge in people with chronic hepatitis B - a pilot randomized controlled study
    Tran, S ; Bennett, G ; Richmond, J ; Tin, N ; Ryan, M ; Hong, T ; Howell, J ; Demediuk, B ; Desmond, P ; Bell, S ; Thompson, A (BMC, 2019-10-23)
    BACKGROUND: The low diagnosis rate and poor access to clinical care among people with CHB is a major barrier to reducing HBV-related morbidity and mortality in Australia. One explanation for this is a lack of disease-specific knowledge among people living with CHB. Health literacy has been shown to be important for maximising engagement with medical care and adherence to recommended management. The 'teach-back' communication strategy has been shown to improve patient understanding in other clinical areas. This study aims to assess disease-specific knowledge; and evaluate the efficacy of the teach-back strategy for improving HBV knowledge, compared to a standard medical consultation. METHOD: A randomized pilot study was conducted between February and June 2017. Participants were recruited from the liver clinic at an inner-city tertiary hospital. English-speaking patients aged ≥18 years and diagnosed with CHB were eligible for the study. Participants were randomised to a control group (medical specialist appointment) and intervention group (teach-back). Knowledge was assessed at baseline, immediately post-intervention and at one month using a validated questionnaire. Participants in the intervention group received a one-on-one teach-back session about CHB. The main outcome measure was a combined knowledge score of the domains assessed - transmission, natural history, epidemiology and prevention and clinical management. RESULTS: Seventy participants were recruited (control n = 32, teach-back n = 38). Mean baseline knowledge score was 19.1 out of 23 with 55 (79%) participants scoring ≥17.3 (defined as high knowledge) (7). Sub-analysis of CHB knowledge domains identified focal deficits concerning transmission and whether HBV is curable. Knowledge scores were found to be positively associated with English proficiency and antiviral treatment experience (p < 0.05). Teach-back was associated with a significant increase in CHB knowledge at early recall (22.5 vs 18.7, p < 0.001) and at 1-month follow-up (21.9 vs 18.7, p < 0.001); there was no improvement in CHB knowledge associated with standard clinical consultant (early recall: 19.6 vs 19.4, p = 0.49, one-month follow-up: 19.5 vs 19.4, p = 0.94). CONCLUSION: In a tertiary hospital liver clinic population, baseline knowledge about CHB was good, but there were focal deficits concerning transmission and potential for cure. Teach-back was associated with improvement in CHB knowledge and it is a simple communication tool suitable for incorporation into a standard medical consultation.

    A qualitative exploration of enablers for hepatitis B clinical management among ethnic Chinese in Australia
    Xiao, Y ; Wallace, J ; Thompson, A ; Hellard, M ; van Gemert, C ; Holmes, JA ; Croagh, C ; Richmond, J ; Papaluca, T ; Hall, S ; Hong, T ; Demediuk, B ; Iser, D ; Ryan, M ; Desmond, P ; Visvanathan, K ; Howell, J (WILEY, 2021-06)
    An estimated 18% of people living with chronic hepatitis B (CHB) in Australia were born in China. While guideline-based care, including regular clinical monitoring and timely treatment, prevent CHB-related cirrhosis, cancer and deaths, over three-quarters of people with CHB do not receive guideline-based care in Australia. This qualitative study aimed to identify enablers to engagement in CHB clinical management among ethnic Chinese people attending specialist care. Participants self-identified as of Chinese ethnicity and who attended specialist care for CHB clinical management were interviewed in Melbourne in 2019 (n = 30). Semi-structured interviews covered experiences of diagnosis and engagement in clinical management services, and advice for people living with CHB. Interviews were recorded with consent; data were transcribed verbatim and thematically analysed. Receiving clear information about the availability of treatment and/or the necessity of long-term clinical management were the main enablers for participants to engage in CHB clinical management. Additional enablers identified to maintain regular clinical monitoring included understanding CHB increases risks of cirrhosis and liver cancer, using viral load indicators to visualize disease status in patient-doctor communication; expectations from family, peer group and medical professionals; use of a patient recall system; availability of interpreters or multilingual doctors; and largely subsidized healthcare services. In conclusion, to support people attending clinical management for CHB, a holistic response from community, healthcare providers and the public health sector is required. There are needs for public health programmes directed to communicate (i) CHB-related complications; (ii) availability of effective and cheap treatment; and that (iii) long-term engagement with clinical management and its benefits.
