Factors associated with hepatitis B knowledge among people of Vietnamese ethnicity in Australia

Despite high hepatitis B (HBV) prevalence among people of Vietnamese ethnicity in Australia and elsewhere, there is limited research on levels of HBV knowledge and factors associated with such knowledge. The aim of this study was to examine HBV knowledge and associated demographic and attitudinal factors among people of Vietnamese ethnicity in Australia. People of Vietnamese ethnicity (n = 966) were recruited through community events and social media groups to complete online surveys measuring HBV knowledge, attitudes towards HBV, levels of mistrust in Western medicine, and demographic characteristics. Findings of this study indicate that levels of knowledge are mixed, with gaps in knowledge related to transmission and treatment of the virus. Those with greater knowledge of HBV tended to be older, have higher levels of formal education, have been tested for HBV, and know someone living with HBV. Those with lower levels of knowledge tended to have more negative attitudes towards the virus and greater levels of mistrust in Western medicine. Given that health literacy is connected to effective communication from health providers, we suggest that there is a need for the development of health promotion and education resources targeted at people of Vietnamese ethnicity and translated into Vietnamese. We propose that such resources be developed in consultation with Vietnamese communities and health providers to ensure that they are culturally appropriate and sensitive to people of Vietnamese ethnicity living in Australia.

Hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia

Research has shown that there are significant gaps in hepatitis B knowledge among migrant communities who are at risk of hepatitis B, such as Chinese and Vietnamese communities. Many students studying within Australia come from countries with high prevalence of hepatitis B. However, there is very little research examining hepatitis B knowledge, screening, or vaccination among university students in Australia or worldwide. The aim of this paper was to measure both levels of and demographic differences in hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia. Online surveys were completed by 112 Chinese- and 95 Vietnamese-identifying students in Australia, measuring knowledge of hepatitis B, engagement in screening and vaccination, and demographic characteristics. Results show that although engagement in screening and vaccination for hepatitis B was high, there were significant gaps in knowledge around transmission of hepatitis B. There were also some key demographic differences in screening and knowledge. For instance, those born in Australia were more likely to have been screened compared to those born Mainland China, Hong Kong, or Vietnam. Chinese students born in Australia had lower levels of knowledge compared to those born in Mainland China or Hong Kong. Among both samples, knowing someone living with hepatitis B was associated with higher levels of knowledge. Findings underscore the need for education-based interventions to address the significant gaps that exist in knowledge around hepatitis B, with a specific need for culturally appropriate resources in a range of languages to cater to the diverse communities who may be at risk of hepatitis B.

The personal and social impact of chronic hepatitis B: A qualitative study of Vietnamese and Chinese participants in Australia

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.

Hepatitis B and Liver Cancer: Community Awareness, Knowledge and Beliefs of Middle Eastern Migrants in Sydney, Australia

Chronic hepatitis B (CHB) is a significant global health challenge given an increasing morbidity and inadequate public health response, Migrant populations are primarily affected by CHB in industrialised countries, and while more than 7% of Australians with CHB were born in Africa or the Middle East, little is known of their awareness or knowledge of viral hepatitis and its impact. This qualitative study, using semi-structured interviews with Assyrian and Arabic community leaders and focus groups (FG) with 66 community members sought to identify hepatitis and liver cancer knowledge and awareness among local Arabic and Assyrian-speaking communities in Western Sydney. Interviews were thematically analysed, with findings framing the topics for the FGs which were analysed using a framework analysis. Themes identified across both methods included limited awareness or knowledge of viral hepatitis or liver cancer, stigma associated with both conditions, variable levels of health literacy and trust in medical practitioners, and fear that receiving “bad news” would deter people from seeking care. Preferred sources of health information were family doctors, family members, the internet and the ethnic media. The study gave valuable information for the design of an educational program and provided useful information for the planning of culturally appropriate hepatitis screening and treatment services for these communities.

Modes of administering sexual health and blood-borne virus surveys in migrant populations: A scoping review

There has been a growing number of sexual health and blood-borne virus (SHBBV) surveys specifically administered to migrant populations. The purpose of this scoping review is to collate available information about how SHBBV surveys have been administered in migrant populations and the effect that mode of administration has on data quality, reliability and other practical considerations, e.g. response rates (RR) and social desirability bias. A methodological framework for scoping reviews was applied. SHBBV survey studies administered to international migrants published since 2000 were included if they contained some description of mode of administration. Ninety one studies were identified for inclusion from Embase, Medline, Web of Science, Google Scholar and supplementary grey literature. 'Interview only' was the most common mode of administration (n = 48), predominately comprising face-to-face interviews. Thirty six studies reported data from 'self-completed' surveys only, with pen-and-paper being most common (n = 17). Few studies (n = 7) combined interview and self-completed methods of survey administration. Sixty one studies did not report (or only partially reported) RR or the data necessary to calculate RR. Of the studies that reported RR, most were missing other key information including method of recruitment, consent procedures and whether incentives were offered. Strengths and limitations of all administration modes are summarised. Guidelines to inform future SHBBV survey research in migrant populations are presented.

Accelerating the elimination of viral hepatitis: a Lancet Gastroenterology & Hepatology Commission

Viral hepatitis is a major public health threat and a leading cause of death worldwide. Annual mortality from viral hepatitis is similar to that of other major infectious diseases such as HIV and tuberculosis. Highly effective prevention measures and treatments have made the global elimination of viral hepatitis a realistic goal, endorsed by all WHO member states. Ambitious targets call for a global reduction in hepatitis-related mortality of 65% and a 90% reduction in new infections by 2030. This Commission draws together a wide range of expertise to appraise the current global situation and to identify priorities globally, regionally, and nationally needed to accelerate progress. We identify 20 heavily burdened countries that account for over 75% of the global burden of viral hepatitis. Key recommendations include a greater focus on national progress towards elimination with support given, if necessary, through innovative financing measures to ensure elimination programmes are fully funded by 2020. In addition to further measures to improve access to vaccination and treatment, greater attention needs to be paid to access to affordable, high-quality diagnostics if testing is to reach the levels needed to achieve elimination goals. Simplified, decentralised models of care removing requirements for specialised prescribing will be required to reach those in need, together with sustained efforts to tackle stigma and discrimination. We identify key examples of the progress that has already been made in many countries throughout the world, demonstrating that sustained and coordinated efforts can be successful in achieving the WHO elimination goals.

Addressing hepatitis C in the foreign-born population: A key to hepatitis C virus elimination in Canada

Hepatitis C virus (HCV) is the leading cause of death from infectious disease in Canada. Immigrants are an important group who are at increased risk for HCV; they account for a disproportionate number of all HCV cases in Canada (~30%) and have approximately a twofold higher prevalence of HCV (~2%) than those born in Canada. HCV-infected immigrants are more likely to develop cirrhosis and hepatocellular carcinoma and are more likely to have a liver-related death during a hospitalization than HCV-infected non-immigrants. Several factors, including lack of routine HCV screening programs in Canada for immigrants before or after arrival, lack of awareness on the part of health practitioners that immigrants are at increased risk of HCV and could benefit from screening, and several patient- and health system-level barriers that affect access to health care and treatment likely contribute to delayed diagnosis and treatment uptake. HCV screening and engagement in care among immigrants can be improved through reminders in electronic medical records that prompt practitioners to screen for HCV during clinical visits and implementation of decentralized community-based screening strategies that address cultural and language barriers. In conclusion, early screening and linkage to care for immigrants from countries with an intermediate or high prevalence of HCV would not only improve the health of this population but will be key to achieving HCV elimination in Canada. This article describes the unique barriers encountered by the foreign-born population in accessing HCV care and approaches to overcoming these barriers.

Factors Associated with Hepatitis C Knowledge Before and After an Educational Intervention among Vietnamese Americans

BACKGROUND

Hepatitis C virus (HCV) is a major cause of chronic liver disease and cancer. Vietnamese Americans are at high risk of HCV infection, with men having the highest US incidence of liver cancer. This study examines an intervention to improve HCV knowledge among Vietnamese Americans.

STUDY

Seven Vietnamese community-based organizations in Pennsylvania and New Jersey recruited a total of 306 Vietnamese participants from 2010 to 2011.

RESULTS

Average knowledge scores for pretest and posttest were 3.32 and 5.88, respectively (maximum 10). After adjusting for confounding variables, age and higher education were positively associated with higher pretest scores and having a physician who spoke English or Vietnamese was negatively associated with higher pretest scores. Additionally, after adjusting for confounding variables, household income, education, and having an HCV-infected family member significantly increased knowledge scores.

CONCLUSIONS

Promotion and development of HCV educational programs can increase HCV knowledge among race and ethnic groups, such as Vietnamese Americans. Giving timely information to at-risk groups provides the opportunity to correct misconceptions, decrease HCV risk behaviors, and encourage testing that might improve timely HCV diagnosis and treatment.

Illness perceptions and explanatory models of viral hepatitis B & C among immigrants and refugees: a narrative systematic review

BACKGROUND

Hepatitis B and C (HBV, HCV) infections are associated with high morbidity and mortality. Many countries with traditionally low prevalence (such as UK) are now planning interventions (screening, vaccination, and treatment) of high-risk immigrants from countries with high prevalence. This review aimed to synthesise the evidence on immigrants' knowledge of HBV and HCV that might influence the uptake of clinical interventions. The review was also used to inform the design and successful delivery of a randomised controlled trial of targeted screening and treatment.

METHODS

Five databases (PubMed, CINHAL, SOCIOFILE, PsycINFO & Web of Science) were systematically searched, supplemented by reference tracking, searches of selected journals, and of relevant websites. We aimed to identify qualitative and quantitative studies that investigated knowledge of HBV and HCV among immigrants from high endemic areas to low endemic areas. Evidence, extracted according to a conceptual framework of Kleinman's explanatory model, was subjected to narrative synthesis. We adapted the PEN-3 model to categorise and analyse themes, and recommend strategies for interventions to influence help-seeking behaviour.

RESULTS

We identified 51 publications including quantitative (n = 39), qualitative (n = 11), and mixed methods (n = 1) designs. Most of the quantitative studies included small samples and had heterogeneous methods and outcomes. The studies mainly concentrated on hepatitis B and ethnic groups of South East Asian immigrants residing in USA, Canada, and Australia. Many immigrants lacked adequate knowledge of aetiology, symptoms, transmission risk factors, prevention strategies, and treatment, of hepatitis HBV and HCV. Ethnicity, gender, better education, higher income, and English proficiency influenced variations in levels and forms of knowledge.

CONCLUSION

Immigrants are vulnerable to HBV and HCV, and risk life-threatening complications from these infections because of poor knowledge and help-seeking behaviour. Primary studies in this area are extremely diverse and of variable quality precluding meta-analysis. Further research is needed outside North America and Australia.

Challenges in managing patients in Australia with chronic hepatitis B: the General Practitioners' perspective

OBJECTIVE

General Practitioners (GPs) are essential to reducing the impact of chronic hepatitis B (CHB) given their clinical management role where only 56% of people with the infection in Australia have been diagnosed. This qualitative study aimed to identify the challenges GPs face in effectively responding to CHB.

METHODS

Semi-structured interviews were conducted with 26 GPs self-identifying as having a 'high caseload' of patients and/or a particular interest in CHB. Participants were recruited from five jurisdictions and came from diverse ethnicities, clinical experience and practice profile. Interview data were analysed according to the principles of grounded theory.

RESULTS

Patient and GP knowledge, a lack of community awareness, and language and cultural diversity impeded the GP response to CHB. Communication with specialists was reported as challenging with unclear referral pathways, limited feedback from specialists after referral, and poor liaison and support for managing people living with CHB. Regulations restricting GPs capacity to respond included the lack of prescribing opportunities, fear of Medicare auditing for screening the populations most at risk, and inadequate financial support given the complexity of CHB and the communities most affected by the infection.

CONCLUSIONS

General Practitioners require additional skills and resources to support the effective management of people with CHB. These include improved awareness and knowledge about the infection, adequate financial resources to support patient management, and effective referral pathways and support.

Managing chronic hepatitis B: A qualitative study exploring the perspectives of people living with chronic hepatitis B in Australia

BACKGROUND

The implementation of a comprehensive public health response to hepatitis B in Australia is urgently required to reduce the increasing burden of hepatitis B infection on the health system and the community. A significant gap in the public health response to hepatitis B is an understanding of how people with chronic hepatitis B (CHB) respond to CHB.

FINDINGS

A qualitative study involving semi-structured interviews and focus group discussions was conducted. Interviews were held with 20 people with CHB from three states of Australia. In addition, four focus group discussions were held with a total of 40 community and health workers from culturally and linguistically diverse communities in four Australian states.People with CHB reported no formal or informal pre or post test discussion with little information about hepatitis B provided at the point of diagnosis. Knowledge deficits about hepatitis B were found among most participants. Few resources are available for people with CHB or their families to assist them in understanding the infection and promoting their health and well-being. A lack of confidence in the professional knowledge of service providers was noted throughout interviews.

CONCLUSIONS

People with CHB need culturally and linguistically appropriate education and information, particularly at the point of diagnosis. Primary health care professionals need the knowledge, skills and motivation to provide appropriate information to people with CHB, to ensure they have the capacity to better manage their infection.

Hepatitis B prevention and control: Lessons from the East and the West

Despite being ten times more common than HIV infection, viral hepatitis has so far not commanded the same public health response worldwide, so a global viral hepatitis treatment program is still a long way from becoming a reality. However, much progress has occurred over the last few decades, with the screening of blood products, sound infection control practices and the introduction of disposable needles and syringes leading to significant reductions in nosocomial hepatitis B transmission in the developed world and increasingly in other countries. The introduction of hepatitis B vaccination in the 1980s and its integration into the Expanded Immunization Program have led to substantial reductions in chronic hepatitis B infection rates in children and to millions of lives saved. The availability of effective antiviral treatment has revolutionized treatment prospects, although access to treatment remains a significant challenge for most developed countries and remains out of reach for developing nations. Some of these breakthroughs have occurred in Asian countries, others in the West, but their unifying features are innovative research, timely clinical translation and a commitment to apply their findings to improve the health of populations, not just individuals. This paper reviews some of the challenges and opportunities for hepatitis B control at the end of the first decade of the third millennium and argues for closer East - West collaborations, to bring in fresh perspectives, avoid duplications of effort and in order to help answer many of the remaining challenges in making hepatitis B history.

Hepatitis B Knowledge, Testing, and Vaccination Among Chinese and Vietnamese Adults in Australia

Hepatitis B is a significant public health challenge within some subpopulations in Australia, including Chinese and Vietnamese migrants. There has been limited research on hepatitis B knowledge and actions in these communities. The authors conducted a self-administered survey among 442 Chinese and 433 Vietnamese in Brisbane. Generally, the knowledge is best described as “moderate.” One in 2 could not identify the sexual transmission risk and less than one third knew that sharing foods or drinks did not spread the disease. The majority of Vietnamese (80%) and 60% of Chinese respondents indicated prior testing. Vaccination was reported in 60% of the Vietnamese and in 52% of the Chinese. Knowledge was better among Chinese people who had been tested and vaccinated compared with those who were nontested and nonvaccinated. Only 3.5% of the Chinese, but 11.6% of the Vietnamese, indicated having a positive test result hepatitis B virus. This study helps identify strategies for programs targeting both communities and practitioners.
