A comprehensive screening and treatment model for reducing disparities in hepatitis B

Exploring factors associated with hepatitis B screening in a multilingual and diverse population

BACKGROUND

Racial/ethnic minorities bear a disproportionate burden of hepatitis B virus (HBV) infection and disease. Disparities in HBV screening contribute to worse outcomes for communities of color. We examined the impact of race/ethnicity, language preference, and having a usual place of care on HBV screening in a multilingual, urban cohort.

METHODS

We used questions from the Health Information National Trends Survey and added validated questions about healthcare access and health literacy. We administered this survey in English, Spanish, and Chinese to a selected convenience sample of San Francisco city/county residents in 2017, with pre-specified targets for populations with known cancer disparities: 25% Spanish-speaking, 25% Chinese-speaking, and 25% Black Americans. Using weighted multivariable logistic regression analyses, we assessed how race/ethnicity, language preference, and having a usual place of care impacts self-report of HBV screening.

RESULTS

Overall, 1027 participants completed the survey (50% of surveys administered in English, 25% in Spanish, and 25% in Chinese). Only 50% of participants reported HBV screening. In multivariable analysis, Black (OR = 0.20, 95% CI 0.08-0.49), Latinx (OR = 0.33, 95% CI 0.13-0.85), Asian (OR = 0.31, 95% CI 0.10, 0.94), and 'Other' race/ethnicity (OR = 0.17, 95% CI 0.05-0.53) respondents had lower odds of HBV screening compared to non-Hispanic White respondents. Participants who had insurance had increased odds of HBV screening (OR = 2.70, 95% CI 1.48-4.93).

CONCLUSIONS

HBV screening disparities persist for Black Americans, Asian Americans, Latinx, and the uninsured. Future studies should explore reasons why current strategies have not been implemented or are not successful, particularly in addressing racial/ethnic and insurance disparities.

Effect of a Community-Based Hepatitis B Virus Infection Detection Combined with Vaccination Program in China

Evidence on the effectiveness of hepatitis B virus (HBV) infection screening and vaccination programs remains rare in China. We used a quasi-experimental method, propensity score matching, to evaluate the effects of a community-based HBV infection detection combined with vaccination (HBVIDV) program in a pilot. Data were retrieved from the HBVIDV program implemented between July 2019 and June 2020. Outcomes were the difference between the treatment and control groups in hepatitis B vaccination (≥1 dose), hepatitis B vaccine series completion (≥3 doses), and serologic evidence of vaccine-mediated immunity. Altogether, 26,180 individuals were included, where 6160 (23.5%) individuals were assigned to the treatment group, and 20,020 (76.5%) individuals were assigned to the control group. After propensity score matching, 5793 individuals were matched. The rates of hepatitis B vaccination, hepatitis B vaccine series completion, and prevalence of vaccine-mediated immunity in the treatment and control groups were 29.0% vs. 17.8%, 22.1% vs. 13.1%, and 38.2% vs. 27.6%, respectively. The HBVIDV program was significantly associated with increased hepatitis B vaccination rate (OR, 1.884, 95% CI 1.725-2.057), hepatitis B vaccine series completion rate (OR, 1.872, 95% CI 1.696-2.065), and prevalence of vaccine-mediated immunity (OR, 1.623, 95% CI 1.501-1.755). The greater magnitude of association between HBVIDV program and outcomes was observed among adults aged 35-54 years and adults who live in rural areas. The HBVIDV program was effective in increasing the hepatitis B vaccination rate, hepatitis B vaccine series completion rate, and prevalence of vaccine-mediated immunity among adults in the pilot. Further focusing the program on special populations and regions may produce more effective results.

Acceptability and Feasibility of Home-Based Hepatitis B Screening Among Haitian Immigrants

Hepatitis B (HBV) is endemic in Haiti, therefore Haitian immigrants should be screened to identify and link affected individuals to care. Current screening approaches are ineffective. We assessed the acceptability and feasibility of home-based screening among Haitian immigrants using community health workers (CHWs). We recruited participants exiting a pragmatic trial evaluating strategies to improve care delivery (NCT02970136). Participants completed an acceptability questionnaire. Blood drawn by CHWs at participants' homes or community sites was tested for hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B core antibody. Of 60 participants, 59 found screening acceptable; 53 had blood drawn. Of those, 45.3% had HBV previously, 49.1% remained susceptible and 5.7% were vaccinated. Respondents cited various reasons community members might find screening unacceptable. The high prior HBV rate highlights the need for effective outreach programs. Home-based HBV screening was both acceptable and feasible among Haitian immigrants.

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.

African Immigrants in New York City with Hepatitis B-Related Hepatocellular Carcinoma Demonstrate High Morbidity and Mortality

Guidelines recommend hepatitis B (HBV) testing in individuals from endemic areas, and if positive, screening for hepatocellular carcinoma (HCC). While screening programs are well established in the Asian immigrant population in New York City (NYC), less is known about the characteristics of HBV/HCC among the African immigrant community. A retrospective review was performed of HCC cases from 2005 to 2018 at our institution. Country of origin was not documented in the electronic medical record; therefore, African immigrant status was approximated using self-identified race/ethnicity, positive HBV status, and an online registry to determine country of origin based on last name. Surnames with the greatest prevalence or density in an African country were considered. Among 4400 patients with HCC, 472 identified as non-Hispanic Black; of these, 86 were HBV+. Based on surname, it was estimated that 33 individuals were likely immigrants from Africa. In this group, median age of HCC diagnosis was 48 years (IQR 43-55). In patients with an available date of HBV diagnosis (n = 24), 17 (71%) were unaware of their HBV status when they presented with HCC. Zero patients were diagnosed with HCC through routine screening, most patients (66%) were diagnosed upon imaging evaluation of symptoms. Twelve patients (36%) underwent resection or transplantation; the remaining 64% were ineligible for surgical treatment. Of the 26 patients with follow-up data, 18 (69%) died of disease or were critically ill at last encounter, and of these, 14 (77%) died within 1 year of HCC diagnosis. In conclusion, African immigrants in NYC with HBV/HCC are at high risk of HCC related mortality at a young age. Most were unaware of their hepatitis status at the time of HCC diagnosis. No patients were enrolled in routine HCC screening; the majority were diagnosed based on imaging obtained for symptoms. Most individuals presented with inoperable disease, and the majority died within months of diagnosis. Awareness of these findings may help healthcare providers improve patient outcomes.

Effectiveness of Interventions for Hepatitis B and C: A Systematic Review of Vaccination, Screening, Health Promotion and Linkage to Care Within Higher Income Countries

Viral hepatitis is a significant global health concern, particularly within low-middle income countries. Diseases historically affecting low-middle income countries, such as viral hepatitis, have become increasingly prevalent within high-income countries due to globalisation and mass international migration. High prevalence of viral hepatitis in migrant populations is of particular concern due to the associated morbidity and mortality, as well as the increased risk of vertical and horizontal transmission in the community. This is compounded by the asymptomatic nature of hepatitis, meaning many of those affected are unaware of their infection status. Long-term effects of viral hepatitis can include liver cirrhosis, liver cancer and liver failure. Therefore, the health needs of vulnerable migrants within high-income countries due to issues associated with viral hepatitis require attention. This includes assessment of measures such as targeted health education, increased screening, linkage to appropriate treatment and follow-up care. Additionally, it is necessary to address migrant healthcare barriers, such as language, economic and social barriers. It is imperative that vulnerable migrant groups gain appropriate access to health services to prevent disease transmission and the widening of health-related disparities within high-income countries.

A mixed-methods approach to understanding perceptions of hepatitis B and hepatocellular carcinoma among ethnically diverse Black communities in South Florida

PURPOSE

Hepatitis B (HBV), the leading cause of hepatocellular carcinoma (HCC), disproportionately affects minorities. Compared to other races, Blacks more often present with advanced HCC and have decreased survival. We observed higher HBV-associated HCC rates among Blacks than reported nationally. In our center, Haitian Blacks had the highest rates of HBV-associated HCC and shorter survival compared to other Blacks. We investigated knowledge and perceptions regarding HBV and HCC among Blacks born in the United States or Haiti.

METHODS

Using community partnerships, participants were recruited via word of mouth, email, social media or from Hepatology clinic. Focus groups were conducted in Haitian Creole or English and stratified by birthplace, gender and infection status. Discussions were audio-recorded and transcribed verbatim. A constant comparative method was used for data analysis; themes are based on conversational details.

RESULTS

There were 55 participants; 49% were male and 27% had chronic HBV. Only 42% of Haitian Blacks knew about HBV prior to participation vs. 78% of African Americans, p 0.03. Both groups expressed that fear, mistrust of the medical establishment, denial and stigma might compel persons to avoid seeking care. Both groups attributed higher rates of late stage HCC diagnosis in Blacks to inadequate financial resources and education. Those with HBV reported confusion regarding their infection and suboptimal communication with healthcare providers.

CONCLUSIONS

In two communities disproportionately affected by HBV, misconceptions about disease transmission, stigma, low health literacy and decreased access to care may limit detection for HBV. Culturally relevant community-based interventions are needed to increase HBV detection.

Interventions to reduce the burden of vaccine-preventable diseases among migrants and refugees worldwide: A scoping review of published literature, 2006-2018

BACKGROUND

Disparities in vaccine-preventable disease (VPD) burden and immunisation coverage between migrants and refugees and their host populations have been described in numerous countries worldwide. Effective strategies are required to reduce the health disparities and immunisation inequities experienced by migrants and refugees.

METHODS

Using Arksey and O'Malley's framework, we conducted a scoping review to identify available literature on interventions aimed at reducing VPD burden among migrants and refugees worldwide. We searched for relevant empirical, peer-reviewed literature published in English between 2006 and 2018 using MEDLINE, Ovid EMBASE, CINAHL, Sociological Abstracts, and Web of Science databases. Relevant information from the studies, including intervention type, details and outcomes, were charted in Microsoft Excel and results were summarised using a descriptive analytical method.

RESULTS

Seventy studies met the inclusion criteria. The number of published studies increased over the years. The majority of studies were conducted in high-income countries. More studies were conducted among migrants (not including refugees) (n = 48, 66%) than specifically among refugees (n = 25, 34%). Interventions were implemented in a variety of settings, including health care (n = 31, 42%), community (n = 29, 39%), off-shore (n = 7, 9%), national (n = 4, 5%), school (n = 2, 3%), and workplace (n = 1, 1%). Studies reported interventions focused at the individual (to facilitate uptake of health services) (n = 4, 5%), community (to raise awareness) (n = 25, 34%), provider (to offer health services) (n = 12, 16%) and/or system (to increase compliance with recommendations) (n = 33, 45%) level. To be effective, interventions were designed to overcome commonly identified barriers to accessing services related to language, culture, distance and cost. Engagement with community members and organisations was an effective way to co-design interventions that address migrants' specific needs.

CONCLUSIONS

Studies emphasised the importance of interventions that address the heterogeneity within and between migrant and refugee populations. Considerable variation in practice remains, therefore more evaluation of interventions is needed to inform policy and programme decision-making.

Online versus in-person training of community health workers to enhance hepatitis B virus screening among Korean Americans: Evaluating cost & outcomes

From 2014 to 2018, we developed and implemented culturally appropriate interventions delivered by community health workers (CHWs) in Pennsylvania and New Jersey. To determine the most cost-effective approach, we recruited 40 predominantly foreign-born Korean American CHWs and used cluster sampling to assign them into two training groups (online training vs. in-person training). We prospectively assessed the cost of training 40 Korean American CHWs and the cost of subsequent HBV educational workshops delivered by the CHWs. We also assessed these costs relative to the success of each training approach in recruiting participants for HBV screening and vaccination. We found that the training costs per participant were higher for in-person training ($1.71 versus $1.12), while workshop costs per participant were lower for in-person training ($2.19 versus $4.22). Workshop attendee costs were comparable. After accounting for site clustering, there were no significant differences in total costs per participant ($24.55 for the online-trained group and $26.05 for the in-person group). In-person trained CHWs were able to generate higher HBV screening and vaccination rates (49.3% versus 21.4% and 17.0% versus 5.9%, respectively) among their participants compared with online-trained CHWs. Given better outcomes and no differences in costs, in-person training dominated the online training option. Despite the potential for efficiency to be gained with online training, CHWs who attended live training outperformed their online-trained colleagues. Elements of the didactic approach or practice with peers in the live session may have contributed to the superior training effectiveness and, ultimately, improved cost-effectiveness of the in-person approach.

Early detection of chronic hepatitis B and risk factor assessment in Turkish migrants, Middle Limburg, Belgium

Background

Turkey is an intermediate hepatitis B virus (HBV) endemic country. However, prevalence among Turkish migrants in Belgium is unknown, especially in those born in Belgium with a foreign-born parent, i.e. second-generation migrants (SGM).

Aims

To evaluate the prevalence of HBV infection and associated risk factors in Turkish first-generation migrants (FGM), i.e. foreign-born, and SGM.

Methods

Between September 2017 and May 2019, free outreach testing for hepatitis B surface antigen (HBsAg), hepatitis B core antibodies (anti-HBc), and antibodies against HBsAg was offered to Turkish migrants in Middle-Limburg, Belgium. Face-to-face questionnaire assessed HBV risk factors. HBsAg positive patients were referred and followed up. Turkish SGM were stratified into birth cohort born before and after 1987, since those born after 1987 should be covered by the universal infant vaccination program.

Results

A total of 1,081/1,113 (97.1%) Turkish did go for HBV testing. Twenty-six (2.4%) were HBsAg positive; 11/26 were unaware of their status and 10/11 were successfully referred. HBsAg prevalence was 3.0% in FGM and 1.5% in SGM, p = .070. Only one out of seven HBsAg positive SGM was born after 1987. In the multiple generalized estimating equations model, the most important risk factors for anti-HBc positivity were male gender (p = .021), older age (p < .001), FGM (p < .001), low educational level of the mother (p = .003), HBV infected mother (p = .008), HBV infected siblings (p = .002), HBV infected other family member (p = .004), gynaecological examination in Turkey or unsafe male circumcision (p = .032) and dental treatment in Turkey (p = .049).

Conclusion

Outreach testing was well-accepted and referral to specialist care was generally successful. National HBV screening should be implemented in the Turkish FGM population and might be considered in SGM not covered by primary prevention strategies.

Chronic Hepatitis B Prevalence Among Foreign-Born and U.S.-Born Adults in the United States, 1999-2016

Hepatitis B virus (HBV) infection remains a major global health problem, exacerbated by poor linkage to care. We aimed to determine the prevalence of HBV infection, exposure, self-reported vaccination, vaccine-induced immunity, disease awareness, and treatment in the United States by birthplace and race/ethnicity during 1999-2016. A total of 47,628 adult participants in the National Health and Nutrition Examination Survey who completed HBV core antibody (anti-HBc) and surface antigen (HBsAg) tests and 47,618 adults who completed HBV surface antibody (anti-HBs) and anti-HBc tests were included in the analysis. HBV infection was defined by positive HBsAg and past exposure by positive anti-HBc. Vaccine-mediated immunity was defined by positive anti-HBs and negative anti-HBc. No significant change in the prevalence of HBV infection was observed between 1999 and 2016 (P = 0.442), affecting 0.35% (95% confidence interval [CI], 0.28-0.45) or 0.84 million adults. In contrast, a significant decrease in HBV exposure and increase in vaccine-mediated immunity was observed. U.S.-born persons had significantly lower prevalence of HBV infection and exposure as well as higher prevalence of vaccine-mediated immunity and self-reported vaccination than foreign-born persons. Prevalence of HBV infection was highest in non-Hispanic Asians in both foreign- (3.85%; 95% CI, 2.97-4.97) and U.S.-born (0.79%; 95% CI, 0.17-3.59) persons during 2011-2016. Among infected persons, liver disease awareness was only 15.19%, and treatment rate was only 4.60%. Conclusion: This study revealed disparities of HBV infection among ethnic/racial groups and between U.S.-born and foreign-born persons. Awareness of liver disease and treatment rate among infected persons was dismal.

Improving Hepatitis B Care in the US: A Case for a New "Ryan White" Program

Chronic hepatitis B infection is common in the United States, yet only a minority of eligible people are screened, vaccinated, and receive treatment. The Ryan White HIV/AIDS program has been a key tool for ensuring that socioeconomically disadvantaged HIV-infected patients have access to care. Many of the same disease and patient attributes that make the Ryan White program necessary and effective for HIV exist in chronic hepatitis B. Thus, we believe that the current Ryan White program should be expanded to care for people with hepatitis B under similar regulations. Considering recent changes proposed to the health insurance marketplace, policymakers should strongly consider inclusion of chronic hepatitis B in the safety-net Ryan White Program.

Predictors and Barriers to Hepatitis B Screening in a Midwest Suburban Asian Population

Despite guidelines recommending hepatitis B virus (HBV) screening among the Asian population, not all Asians are screened. We assessed barriers to and factors predicting HBV screening in Michigan. Adults residing in Southeast Michigan self-identifying as Asian were surveyed at Asian grocery stores, restaurants, churches, and community events. 404 persons participated in the survey, 54 % were women, median age was 51 years, 63 % were Chinese, and 93.8 % were born outside the U.S. 181 (44.8 %) had not or could not recall having been screened for HBV. Of these, 89 % said their primary care physicians (PCP) had never brought up screening. Unscreened participants were more likely to think HBV is genetically inherited and cannot be treated than those who had been screened. They were also more likely to think they should avoid close contact with others, would bring shame to their families, and lose their job, if found to be infected with HBV. Among 223 (55.2 %) who had been screened, 48 % said their PCP had the greatest influence in their decision to be screened and 70.9 % said they were screened at a doctor's visit. Screened participants were more likely to know someone with HBV, have a PCP, and have health insurance. Logistic regression analysis showed knowing someone with HBV was the only predictor for screening. Despite guidelines for HBV screening, only half of the Asian Americans surveyed had been screened. Increasing awareness among PCPs is needed to increase HBV screening in this population.

Determinants of uptake of hepatitis B testing and healthcare access by migrant Chinese in the England: a qualitative study

Background

Global migration from hepatitis B endemic countries poses a significant public health challenge in receiving low-prevalence countries. In the UK, Chinese migrants are a high risk group for hepatitis B. However, they are an underserved population that infrequently accesses healthcare. This study sought to increase understanding of the determinants of hepatitis B testing and healthcare access among migrants of Chinese ethnicity living in England.

Methods

We sought to obtain and integrate insights from different key stakeholders in the system. We conducted six focus group discussions and 20 in-depth interviews with community members and patients identifying themselves as ‘Chinese’, and interviewed 21 clinicians and nine health service commissioners. Data were thematically analysed and findings were corroborated through two validation workshops.

Results

Three thematic categories emerged: knowledge and awareness, visibility of the disease, and health service issues. Low disease knowledge and awareness levels among community members contributed to erroneous personal risk perception and suboptimal engagement with services. Limited clinician knowledge led to missed opportunities to test and inaccurate assessments of infection risks in Chinese patients. There was little social discourse and considerable stigma linked to the disease among some sub-sections of the Chinese population. A lack of visibility of the issue and the population within the health system meant that these health needs were not prioritised by clinicians or commissioners. Service accessibility was also affected by the lack of language support. Greater use of community outreach, consultation aids, ‘cultural competency’ training, and locally adapted testing protocols may help.

Conclusions

Hepatitis B among migrants of Chinese ethnicity in England can be characterised as an invisible disease in an invisible population. Multi-modal solutions are needed to tackle barriers within this population and the health system.

Provider, Patient, and Practice Factors Shape Hepatitis B Prevention and Management by Primary Care Providers

GOALS

To evaluate provider knowledge, attitudes and barriers to hepatitis B virus (HBV) care and management practices across diverse primary care settings.

BACKGROUND

Factors influencing adherence to recommended HBV screening and management guidelines are poorly defined.

MATERIALS AND METHODS

Providers across various health care settings in San Francisco were surveyed. Multivariate analyses were used to identify factors associated with recommended HBV screening, vaccination, and disease monitoring.

RESULTS

Of 277 (41.3%) responding providers, 42% reported performing HBV screening in >50% of at-risk patients, and 49%, HBV vaccination in >50% of eligible patients. Most reported appropriate monitoring of a majority of HBV-infected patients with alanine aminotransferase (79%) and HBV viral load (67%) every 6 to 12 months, but performed any hepatocellular carcinoma screening in 49%. Provider factors significantly associated with HBV screening were speaking an Asian language [odds ratio (OR), 3.27], offering HBV treatment (OR, 3.00), having >25% of Asian patients in practice (OR, 2.10), practicing in safety net settings (OR, 7.51) and having higher barrier score (OR, 0.74). Appropriate HBV monitoring was associated with provider speaking an Asian language (OR, 3.43) and provider age (OR, 0.68/decade). Hepatocellular carcinoma screening was associated with having >25% of patients speaking English as a second language (OR, 4.26) and practicing in safety net settings (OR, 0.14).

CONCLUSIONS

Rates of adherence to HBV guidelines were suboptimal irrespective of practice setting and were influenced by certain provider, patient and practice factors. This study reinforces the importance of engaging primary care providers in development, dissemination, and implementation of evidence-based HBV practice guidelines.

Improving access to health care for chronic hepatitis B among migrant Chinese populations: A systematic mixed methods review of barriers and enablers

Migrant Chinese populations in Western countries have a high prevalence of chronic hepatitis B but often experience poor access to health care and late diagnosis. This systematic review aimed to identify obstacles and supports to timely and appropriate health service use among these populations. Systematic searches resulted in 48 relevant studies published between 1996 and 2015. Data extraction and synthesis were informed by models of healthcare access that highlight the interplay of patient, provider and health system factors. There was strong consistent evidence of low levels of knowledge among patients and community members; but interventions that were primarily focused on increasing knowledge had only modest positive effects on testing and/or vaccination. There was strong consistent evidence that Chinese migrants tend to misunderstand the need for health care for hepatitis B and have low satisfaction with services. Stigma was consistently associated with hepatitis B, and there was weak but consistent evidence of stigma acting as a barrier to care. However, available evidence on the effects of providing culturally appropriate services for hepatitis B on increasing uptake is limited. There was strong consistent evidence that health professionals miss opportunities for testing and vaccination. Practitioner education interventions may be important, but evidence of effectiveness is limited. A simple prompt in patient records for primary care physicians improved the uptake of testing, and a dedicated service increased targeted vaccination coverage for newborns. Further development and more rigorous evaluation of more holistic approaches that address patient, provider and system obstacles are needed.

Ethnic Disparities in Chronic Hepatitis B Infection: African Americans and Hispanic Americans

Chronic infection with hepatitis B affects more than 240 million persons worldwide and is a major public health concern. Despite national and global initiatives to promote hepatitis B elimination, including newborn vaccination, catch up vaccination in adolescents and high-risk adults, screening of the blood supply and treatment of those in need, both new infections and a reservoir of chronic infections continue to result in morbidity and mortality. As with many chronic diseases, racial and ethnic disparities are seen in hepatitis B virus infection.

Purpose of Review

The goal of this review is to synthesize the data concerning the burden of hepatitis B infection in African Americans and Hispanics, two racial/ethnic groups in the United States who encounter barriers in access to care, low engagement in care and low utilization of diagnostic and treatment services.

Recent Findings

Recent data, though sparse in certain areas, continue to suggest differences in rates of incidence and prevalence of hepatitis B virus infection in African Americans, and differences in screening, specialty referral and initiation of therapy for African Americans and Hispanics. Data are lacking about differences in liver disease progression and manifestations in both African Americans and Hispanics.

Summary

Disparities in hepatitis B diagnosis, disease management, treatment and prevention remain for African Americans and Hispanics. These disparities require a commitment from governmental and public health organizations. The efforts should include increasing vaccination in those most susceptible to infection, screening those at highest risk for infection, initiating antiviral therapy in those who require it and monitoring for liver-related complications, such as decompensated cirrhosis and hepatocellular carcinoma in the chronically infected. This multi-pronged approach is necessary to realize hepatitis B elimination.

Hepatitis B Screening & Vaccination Behaviors in a Community-based Sample of Chinese & Korean Americans in New York City

OBJECTIVES

As Asian Americans are dis- proportionately affected by the hepatitis B virus (HBV), we explored predictors of HBV screening and vaccination among Chinese and Korean Americans.

METHODS

We used cross-sectional data from a com- munity-based sample of Chinese Americans (N = 502) and Korean Americans (N = 487) residing in the metropolitan New York City area during 2008-2009. Logistic regression models were stratified by Asian-American subgroup and sex to predict HBV screening (for the entire sam- ple) and HBV vaccination (among those not HBV positive).

RESULTS

Overall, screening rates were high (71.3% among Chinese and 70.1% among Koreans). The majority of respondents were aware of HBV; however, knowledge about HBV transmission was low. In logistic regression, a physician recommendation was consistently associated with HBV screening and vaccination outcomes across all groups; having heard of HBV was significantly associated with screening and vaccination among Chinese males and screening among Korean males and females. Screening and vaccination barriers were reported among all groups, and included lack of knowledge and feeling well/having no health issues.

CONCLUSIONS

Targeted efforts in these at-risk communities are necessary to improve HBV knowledge, address misinformation about HBV, and eliminate provider-, patient-, and resource-related barriers to HBV screening and vaccination.

The Asian Grocery Store-Based Cancer Education Program: Creating New Education Modules

Operating since 1994, the UCSD Moores Cancer Center's Asian Grocery Store-Based Cancer Education Program (the Program) is a proven and sustainable strategy for disseminating cancer and poison control information to Asian and Pacific Islander (API) communities. This paper describes the process taken to identify health topics that can be readily addressed within the Program's infrastructure and reports results of the pilot testing of the educational module that was developed by following that process. The development of each new module is guided by the Health Belief Model and the Tipping Point Model. The process starts with the selection of a health topic demonstrating pressing need and treatment options in the API community. Then, using the Pareto principle, reasonably modifiable risk factors are chosen to be addressed in the module. "Sticky messaging" for the modifiable risk factors is developed to package the health information as memorable and transmissible calls-to-action. Finally, grocery store outreaches were used to pilot test the new module to assess its effectiveness at facilitating health care information to API community members. By adhering to the steps described in this paper, the authors were able to: (1) select liver cancer as a pressing API health issue that could be positively impacted by the Program; (2) identify reasonably modifiable risk factors for the chosen health issue; (3) generate compelling call-to-action messages to decrease risk of exposure; and (4) demonstrate the cultural and linguistic alignment of the liver cancer control module. The development and testing of new health education modules follow a methodical process guided by scientific principles. Understanding and employing the elements of an existing evidence-based and sustainable health education program can increase the likelihood of success in addressing the health needs of the API community.

Barriers and opportunities for hepatitis B testing and contact tracing in a UK Somali population: a qualitative study

BACKGROUND

Chronic hepatitis B virus (HBV) infection frequently causes liver disease, and early identification can improve outcome. The burden of chronic HBV infection in many economically developed nations lies in migrant populations. Targeted HBV testing of migrants, and contact tracing for those diagnosed, are public health objectives but uptake has been fragmentary. This qualitative study aimed to investigate understanding of hepatitis B and response to testing and contact tracing amongst people of Somali ethnicity living in Bristol, UK.

METHODS

The views of 30 people of Somali ethnicity living in Bristol were explored through focus groups and semi-structured interviews. Transcripts of audio-recorded interviews and focus groups were imported into NVivo10 and inductive thematic analysis undertaken.

RESULTS

Most participants lacked awareness of hepatitis B, and often co-identified hepatitis B with 'jaundice'. There were frequent misconceptions regarding transmission, natural history and diagnosis, with hepatitis B commonly viewed as a relatively trivial, short lived, symptomatic disease. Hepatitis B was generally not stigmatised. Lack of understanding of the disease was cited as the major barrier to targeted testing and contact tracing.

CONCLUSION

These findings suggest public health initiatives to promote hepatitis B testing and contact tracing within migrant Somali populations should focus on improving hepatitis B understanding, particularly its natural history and diagnosis, and avoid translation of 'hepatitis B' into terms meaning 'jaundice' to address misperception of low susceptibility and low severity.

Asian-Pacific clinical practice guidelines on the management of hepatitis B: a 2015 update

Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Hepatitis prevention project in the Korean American community in Killeen, Texas

Educational efforts related to viral hepatitis have the potential to increase awareness and identify chronically infected individuals and can lead to successful vaccination strategies. However, in underserved semirural communities, such as the Korean American community in Killeen, Texas, these outreach activities are lacking. The GanYum ("hepatitis" in Korean) Prevention Project aimed to evaluate thoughts/behaviors, assess vulnerability, and educate Korean Americans on hepatitis B and C. Two outreach events were held at a Korean church and a Korean market (O'Mart) to provide education, screening, and outreach about viral hepatitis. Ninety-six patients were screened at two events. Five patients were found to be positive for hepatitis B surface antigen and were referred to their primary care physicians and the liver clinic at Scott & White Healthcare in Temple, Texas. Fifty-one patients (53%) were found to be immune to hepatitis B, and 40 patients (42%) were hepatitis B vulnerable. We demonstrated that the prevalence of chronic hepatitis B in Koreans in our study is similar to the previously documented prevalence (5%). Our educational efforts were successful in changing perceptions regarding the modes of transmission and exacerbating factors of chronic viral hepatitis and encouraged participants to seek care for their liver diseases, if needed. We found that both venues (the church and Korean market) were appropriate to screen and educate participants; churches seemed to have a more engaged audience.

Cluster-Randomized Trial to Increase Hepatitis B Testing among Koreans in Los Angeles

BACKGROUND

In the United States, Korean immigrants experience a disproportionately high burden of chronic hepatitis B (HBV) viral infection and associated liver cancer compared with the general population. However, despite clear clinical guidelines, HBV serologic testing among Koreans remains persistently suboptimal.

METHODS

We conducted a cluster-randomized trial to evaluate a church-based small group intervention to improve HBV testing among Koreans in Los Angeles. Fifty-two Korean churches, stratified by size (small, medium, large) and location (Koreatown versus other), were randomized to intervention or control conditions. Intervention church participants attended a single-session small-group discussion on liver cancer and HBV testing, and control church participants attended a similar session on physical activity and nutrition. Outcome data consisted of self-reported HBV testing obtained via 6-month telephone follow-up interviews.

RESULTS

We recruited 1,123 individuals, 18 to 64 years of age, across the 52 churches. Ninety-two percent of the sample attended the assigned intervention session and 86% completed the 6-month follow-up. Sample characteristics included were as follows: mean age 46 years, 65% female, 97% born in Korea, 69% completed some college, and 43% insured. In an intent-to-treat analysis, the intervention produced a statistically significant effect (OR = 4.9, P < 0.001), with 19% of intervention and 6% of control group participants reporting a HBV test.

CONCLUSION

Our intervention was successful in achieving a large and robust effect in a population at high risk of HBV infection and sequelae.

IMPACT

The intervention was fairly resource efficient and thus has high potential for replication in other high-risk Asian groups.

Immigration and viral hepatitis

WHO estimates reveal that the global prevalence of viral hepatitis may be as high as 500 million, with an annual mortality rate of up to 1.3 million individuals. The majority of this global burden of disease is borne by nations of the developing world with high rates of vertical and iatrogenic transmission of HBV and HCV, as well as poor access to healthcare. In 2013, 3.2% of the global population (231 million individuals) migrated into a new host nation. Migrants predominantly originate from the developing countries of the south, into the developed economies of North America and Western Europe. This mass migration of individuals from areas of high-prevalence of viral hepatitis poses a unique challenge to the healthcare systems of the host nations. Due to a lack of universal standards for screening, vaccination and treatment of viral hepatitis, the burden of chronic liver disease and hepatocellular carcinoma continues to increase among migrant populations globally. Efforts to increase case identification and treatment among migrants have largely been limited to small outreach programs in urban centers, such that the majority of migrants with viral hepatitis continue to remain unaware of their infection. This review summarizes the data on prevalence of viral hepatitis and burden of chronic liver disease among migrants, current standards for screening and treatment of immigrants and refugees, and efforts to improve the identification and treatment of viral hepatitis among migrants.

Chronic hepatitis B and liver cancer risks among Asian immigrants in New York City: Results from a large, community-based screening, evaluation, and treatment program

BACKGROUND

Hepatitis B virus (HBV) infection, the predominant cause of hepatocellular carcinoma (HCC) worldwide, disproportionately affects Asian Americans. Limited data exist on the variability and characteristics of infection that determine disease progression risk within U.S. Asian ethnic subgroups.

METHODS

Retrospective analyses were conducted on a large, community-based HBV screening and treatment program in New York City (NYC). From 2004 to 2008, the program enrolled 7,272 Asian-born individuals. Determinants of HBV seroprevalence were calculated and risk factors for HCC progression were compared across Asian subgroups.

RESULTS

Among newly tested individuals, 13% were HBV positive. Seroprevalence varied significantly with age, gender, education, birthplace, and family history of infection. Chinese-born individuals, particularly from the Fujian province, had the highest seroprevalence (23.2% and 33.1%, respectively). Clinical and virologic characteristics placed HBV-infected individuals at significant risk for HCC. Significant differences in HCC risk existed among Asian subgroups in bivariate analysis, including age, gender, HBV viral load, and HBeAg status. Differences in HBV genotype and family history of HCC may further HCC risk among subgroups.

CONCLUSIONS

Asian immigrants in NYC have a high prevalence of HBV infection and are at significant risk of disease progression and HCC. Although heterogeneity in HBV seroprevalence was found by Asian subgroups, HCC risk among infected individuals was primarily explained by age and gender differences. Country and province of birth, age, and gender may further explain seroprevalence differences.

IMPACT

Findings provide estimates of HBV burden in Asian ethnic subgroups and identify high-risk groups to target for screening and treatment that can prevent HCC.

Health-related quality of life and health behaviors in a population-based sample of older, foreign-born, Chinese American adults living in New York City

Although the New York City Chinese population aged ≥ 65 years increased by 50% between 2000 and 2010, the health needs of this population are poorly understood. Approximately 3,001 Chinese individuals from high-density Asian American New York City areas were included in the REACH U.S. Risk Factor Survey; 805 (26.8%) were aged ≥ 65 years and foreign-born. Four health-related quality of life and three behavioral risk factor outcome variables were examined. Descriptive statistics were conducted by gender, and logistic regression models assessed sociodemographic and health factors associated with each outcome. Few women were current smokers (1.3% vs. 14.8% of men), 19% of respondents ate fruits and vegetables more than or equal to five times daily, and one-third of individuals received sufficient weekly physical activity. Days of poor health were similar to the national population aged ≥ 65 years, while self-reported fair or poor health was much greater among our Chinese sample; over 60% of respondents rated their health as fair or poor. Lower education and lower obesity were significantly associated with cigarette smoking among men, and older age was significantly associated with insufficient physical activity overall. Female gender was significantly associated with all poor health days; older age was significantly associated with poor days of physical health, and lower income was significantly associated with poor days of physical health and fair or poor self-reported health. This study provides important health-related information on a rapidly growing older population and highlights future research areas to inform culturally appropriate health promotion and disease prevention strategies and policies within community-based settings.

Defining an integrative approach for health promotion and disease prevention: a population health equity framework

Eliminating health disparities in racial/ethnic minority and underserved populations requires a paradigm shift from biomedical approaches that are disease-focused to a health equity framework that aims to achieve optimal health for all by targeting social and structural determinants of health. We describe the concepts and parallel approaches that underpin an integrative population health equity framework and present the experience of NYU Center for the Study of Asian American Health (CSAAH) in applying the framework to guide its work. Applying an integrative framework has deepened our community engagement efforts, our understanding of the multi-level contextual factors that influence health, and our capacity to advance health equity for Asian American communities through action-oriented research and policy. This framework and experience is applicable to researchers and community members working with other underserved populations.

Physical activity, fruit and vegetable intake, and health-related quality of life among older Chinese, Hispanics, and Blacks in New York City

OBJECTIVES

We explored the relationship between health-related quality of life (HRQOL) and adequate physical activity (PA) and fruit and vegetable (F&V) intake among racial/ethnic minority groups aged 60 years or older living in New York City (NYC).

METHODS

Survey data from 2009 to 2012 targeted minority groups in NYC ethnic enclaves; we analyzed 3594 individuals (Blacks, Hispanics, and Chinese) aged 60 years or older. Descriptive statistics were run; unadjusted and adjusted logistic regression evaluated the relationship of HRQOL with PA and F&V intake.

RESULTS

Hispanics were most likely to engage in sufficient PA and eat recommended F&Vs and had significantly worse HRQOL. After multivariable adjustment, significant associations were found between PA and self-reported health, activity limitation and physical health days for all groups, and PA and mental health days for Hispanics. Significant associations were found between F&V intake and physical health days for Hispanics and F&V intake and self-reported health for Chinese.

CONCLUSIONS

Findings indicated variations between HRQOL and PA by racial/ethnic subgroup. Despite being highly insured, recommendations for PA and F&V intake were not met. There is a need to promote healthy living behaviors among aging NYC racial/ethnic populations.

Moving the dial to advance population health equity in New York City Asian American populations

The shift toward a health equity framework for eliminating the health disparities burden of racial/ethnic minority populations has moved away from a disease-focused model to a social determinants framework that aims to achieve the highest attainment of health for all. The New York University Center for the Study of Asian American Health (CSAAH) has identified core themes and strategies for advancing population health equity for Asian American populations in New York City that are rooted in the following: social determinants of health; multisectoral, community-engaged approaches; leveraging community assets; improved disaggregated data collection and access to care; and building sustainability through community leadership and infrastructure-building activities. We describe the strategies CSAAH employed to move the dial on population health equity.

Strategies for addressing vaccine hesitancy - A systematic review

The purpose of this systematic review is to identify, describe and assess the potential effectiveness of strategies to respond to issues of vaccine hesitancy that have been implemented and evaluated across diverse global contexts.

METHODS

A systematic review of peer reviewed (January 2007-October 2013) and grey literature (up to October 2013) was conducted using a broad search strategy, built to capture multiple dimensions of public trust, confidence and hesitancy concerning vaccines. This search strategy was applied and adapted across several databases and organizational websites. Descriptive analyses were undertaken for 166 (peer reviewed) and 15 (grey literature) evaluation studies. In addition, the quality of evidence relating to a series of PICO (population, intervention, comparison/control, outcomes) questions defined by the SAGE Working Group on Vaccine Hesitancy (WG) was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria; data were analyzed using Review Manager.

RESULTS

Across the literature, few strategies to address vaccine hesitancy were found to have been evaluated for impact on either vaccination uptake and/or changes in knowledge, awareness or attitude (only 14% of peer reviewed and 25% of grey literature). The majority of evaluation studies were based in the Americas and primarily focused on influenza, human papillomavirus (HPV) and childhood vaccines. In low- and middle-income regions, the focus was on diphtheria, tetanus and pertussis, and polio. Across all regions, most interventions were multi-component and the majority of strategies focused on raising knowledge and awareness. Thirteen relevant studies were used for the GRADE assessment that indicated evidence of moderate quality for the use of social mobilization, mass media, communication tool-based training for health-care workers, non-financial incentives and reminder/recall-based interventions. Overall, our results showed that multicomponent and dialogue-based interventions were most effective. However, given the complexity of vaccine hesitancy and the limited evidence available on how it can be addressed, identified strategies should be carefully tailored according to the target population, their reasons for hesitancy, and the specific context.

Community-based hepatitis B screening: what works?

INTRODUCTION

Chronic hepatitis B (CHB) affects over 350 million people worldwide and can lead to life-threatening complications, including liver failure and hepatocellular cancer (HCC). Modern antiviral therapies could stem the rising tide of hepatitis B-related HCC, provided that individuals and populations at risk can be reliably identified through hepatitis B screening and appropriately linked to care. Opportunistic disease screening cannot deliver population-level outcomes, given the large number of undiagnosed people, but they may be achievable through well-organized and targeted community-based screening interventions.

MATERIAL AND METHODS

This review summarizes the experience with community-based CHB screening programs published in the English-language literature over the last 30 years.

RESULTS

They include experiences from Taiwan, the USA, The Netherlands, New Zealand, and Australia. Despite great variability in program setting and design, successful programs shared common features, including effective community engagement incorporating the target population's cultural values and the ability to provide low-cost or free access to care, including antiviral treatment.

CONCLUSION

While many questions still remain about the best funding mechanisms to ensure program sustainability and what the most effective strategies are to ensure program reach, linkage to care, and access to treatment, the evidence suggests scope for cautious optimism. A number of successful, large-scale initiatives in the USA, Asia-Pacific, and Europe demonstrated the feasibility of community-based interventions in effectively screening large numbers of people with CHB. By providing an effective mechanism for community outreach, scaling up these interventions could deliver population-level outcomes in liver cancer prevention relevant for many countries with a large burden of disease.

Community health worker hepatitis B education for Cambodian American men and women

BACKGROUND

Cambodian Americans have high rates of chronic hepatitis B virus (HBV) infection and liver cancer. There is very limited information about the utility of community health worker (CHW) approaches to cancer education for Asian American men. We have previously reported our positive findings from a trial of CHW education about HBV for Cambodian Americans who had never been tested for HBV. This report describes similarities and differences between the outcomes of our CHW HBV educational intervention among Cambodian American men and women.

METHODS

The study group for this analysis included 87 individuals (39 men and 48 women) who were randomized to the experimental (HBV education) arm of our trial, participated in the CHW educational intervention, and provided follow-up data six months post-intervention. We examined HBV testing rates at follow-up, changes in HBV-related knowledge between baseline and follow-up, and barriers to HBV testing (that were reported to CHWs) by gender.

RESULTS

At follow-up, 15% of men and 31% of women reported they had received a HBV test (p=0.09). HBV-related knowledge levels increased significantly among both men and women. With respect to HBV testing barriers, women were more likely than men to cite knowledge deficits, and men were more likely than women to cite logistic issues.

DISCUSSION

Our study findings indicate that CHW interventions can positively impact knowledge among Cambodian American men, as well as women. They also suggest CHW interventions may be less effective in promoting the use of preventive procedures by Cambodian American men than women. Future CHW research initiatives should consider contextual factors that may differ by gender and, therefore, potentially influence the relative effectiveness of CHW interventions for men versus women.

Community-based prevention of hepatitis-B-related liver cancer: Australian insights

PROBLEM

Although most primary hepatocellular cancers (HCCs) are attributable to chronic viral hepatitis and largely preventable, such cancers remain a leading cause of cancer-related mortality wherever chronic hepatitis B is endemic.

APPROACH

Many HCCs could be prevented by increasing awareness and knowledge of hepatitis B, optimizing the monitoring of chronic hepatitis B and using antiviral treatments - but there are gaps in the implementation of such strategies.

LOCAL SETTING

The "B Positive" programme, based in Sydney, Australia, is designed to improve hepatitis-B-related health outcomes among immigrants from countries with endemic hepatitis B. The programme offers information about disease screening, vaccination and treatment options, as well as optimized access to care.

RELEVANT CHANGES

The B Positive programme has been informed by economic modelling. The programme offers culturally tailored education on chronic hepatitis B to target communities and their health practitioners and regular follow-up through a population-based registry of cases.

LESSONS LEARNT

As the costs of screening for chronic hepatitis B and follow-up are relatively low and less than one in every four cases may require antiviral drugs, optimizing access to treatment seems an appropriate and cost-effective management option. The identification and accurate staging of cases and the judicious use of antiviral medications are predicated upon an informed and educated health workforce. As establishing community trust is a lengthy process, delaying the implementation of programmes against chronic hepatitis B until antiviral drugs become cheaper is unwarranted.

Hepatitis B management in vulnerable populations: gaps in disease monitoring and opportunities for improved care

BACKGROUND

Hepatitis B (HBV) is prevalent in certain US populations and regular HBV disease monitoring is critical to reducing associated morbidity and mortality. Adherence to established HBV monitoring guidelines among primary care providers is unknown.

AIMS

The purpose of this study was to evaluate HBV disease monitoring patterns and factors associated with adherence to HBV management guidelines in the primary care setting.

METHODS

Primary providers within the San Francisco safety net healthcare system were surveyed for HBV management practices, knowledge, attitudes, and barriers to HBV care. Medical records from 1,727 HBV-infected patients were also reviewed retrospectively.

RESULTS

Of 148 (45 %) responding providers, 79 % reported ALT and 44 % reported HBV viral load testing every 6-12 months. Most providers were knowledgeable about HBV but 43 % were unfamiliar with HBV management guidelines. Patient characteristics included: mean age 51 years, 54 % male and 67 % Asian. Within the past year, 75 % had ALT, 24 % viral load, 21 % HBeAg tested, and 40 % of at-risk patients had abdominal imaging for HCC. Provider familiarity with guidelines (OR 1.02, 95 % CI 1.00-1.03), Asian patient race (OR 4.18, 95 % CI 2.40-7.27), and patient age were associated with recommended HBV monitoring. Provider HBV knowledge and attitudes were positively associated, while provider age and perceived barriers were negatively associated with HCC surveillance.

CONCLUSIONS

Comprehensive HBV disease monitoring including HCC screening with imaging were suboptimal. While familiarity with AASLD guidelines and patient factors were associated with HBV monitoring, only provider and practice factors were associated with HCC surveillance. These findings highlight the importance of targeted provider education to improve HBV care.

Hepatitis B testing and access to care among racial and ethnic minorities in selected communities across the United States, 2009-2010

Hepatitis B virus (HBV) infection is widely prevalent among racial and ethnic minorities in the United States; however, few data have been available regarding HBV testing and referral to care for these populations. Using survey data collected in 2009-2010 from the Racial and Ethnic Approaches to Community Health (REACH) across the U.S., we assessed rates and determinants of hepatitis B testing and access to care in 28 minority communities in the U.S. Of 53,896 respondents, 21,129 (39.2%) reported having been tested for hepatitis B. Of the 1,235 who reported testing positive, 411 (33.3%) reported currently receiving specialty care. After controlling for demographic and socioeconomic characteristics, the likelihood of having been tested for hepatitis B and receiving care if infected was higher among males, non-English speaking persons, and those having health insurance compared to their counterparts. Compared to college graduates, respondents without a college education were less likely to get tested for hepatitis B.

CONCLUSION

These data indicate that more than half of racial/ethnic minority persons in these communities had not been tested for hepatitis B, and only about one-half of those who tested positive had ever received treatment. More state and federal efforts are needed to screen racial/ethnic minorities, especially foreign-born persons, for HBV and link those with infection to care.

Hepatitis Outreach Network: a practical strategy for hepatitis screening with linkage to care in foreign-born communities

BACKGROUND & AIMS

Many foreign-born persons in the US are at high risk of chronic hepatitis B (HBV) and C (HCV) infections, yet are not aware of their infection, and lack healthcare coverage or linkage to care.

METHODS

A unique partnership, the Hepatitis Outreach Network, combines the expertise and resources of the Mount Sinai School of Medicine, the NYC Department of Health and Mental Hygiene, and community-based organizations, to provide education, screening and link to care in communities with high prevalence of chronic viral hepatitis. Comprehensive HBV and HCV screening identifies infected patients, who then receive further evaluation from either local or Mount Sinai physicians, combined with patient-navigators who organize follow-up visits.

RESULTS

Of 1603 persons screened, 76 had HBV and 75 had HCV. Importantly, screening for HCV based on traditional risk factors would have missed 67% of those who tested positive. Of the 76 persons with HCV infection, 49 (64%) received a medical evaluation (26 with local providers and 23 at Mount Sinai). Of the 49 HCV-infected persons evaluated, treatment was recommended in 11 and begun in 8 (73%). Of the 76 persons with HBV infection, 43 (57%) received a medical evaluation (31 with local providers and 12 at Mount Sinai). Of the 43 HBV-infected persons evaluated, treatment was recommended and begun in 5 (100%).

CONCLUSIONS

Hepatitis Outreach Network has successfully established novel proof of concept for identifying HBV and HCV infections in foreign-born persons through use of several unique elements that effectively link them to care.

Hepatitis B infection in the Asian and Latino communities of Alameda County, California

The purpose of this study is to estimate the prevalence of the hepatitis B virus (HBV) infection and to examine factors related to HBV screening and vaccination among various Asian and Latino populations in Alameda County, CA. A cross-sectional study was conducted on Asian and Latino residents who registered with an HBV screening program from June 2009-February 2011. All participants completed a sociodemographic survey and were offered free HBV blood testing for the hepatitis B surface antigen (HBsAg) and antibody (HBsAb). The 3-shot vaccination series was provided for free to unprotected participants. Among the 792 registered participants, 84.4% (n = 669) received a blood test. Of the 669 tested participants, 7.9% (n = 53) tested HBV positive (HBsAg+, HBsAb -), 46.2% (n = 309) were protected (HBsAg -, HBsAb +), and 45.9% (n = 307) were susceptible to HBV infection (HBsAg -, HBsAb -). Among those unprotected, 60% completed the vaccine series. Multivariate analysis showed that being Vietnamese (OR = 5.53, 95% CI 1.54, 19.85), living in the US >10 years (OR = 2.12, 95% CI 1.13, 3.97), and having at least a college education (OR = 2.55, 95% CI 1.28, 5.07) were important predictors of vaccine completion. Given the various HBsAg + prevalence, screening, and vaccine completion rates among the different ethnic groups in this study, it is clear that different approaches in screening and vaccinating individual ethnic groups for hepatitis B are warranted.

Identification and treatment of chronic hepatitis B in Chinese migrants: results of a project offering on-site testing in Rotterdam, The Netherlands

BACKGROUND & AIMS

Migrants born in countries where hepatitis B is endemic are a risk group for chronic hepatitis B virus (HBV) infection. Treatment options have improved, but due to the asymptomatic nature of chronic HBV infection, the majority of patients remain unidentified.

METHODS

In 2009, a campaign targeting the Chinese community was held in the city of Rotterdam, The Netherlands. The campaign combined disease awareness activities with free HBV testing at outreach locations. Chronically HBV infected patients were referred to specialist care based on a referral guideline. Before and after the campaign, knowledge of chronic hepatitis B was measured through questionnaires in a convenience sample of the target population (n=285 and n=277).

RESULTS

In a period of 3 months, 13 outreach activities took place and 1090 Chinese migrants were tested for HBV. Forty-nine percent had serological signs of a past or recent HBV infection and 8.5% (n=92) were chronically infected. Thirty-eight percent (n=35) of chronically infected patients were referred for evaluation by a specialist and of these, 15 started antiviral treatment within 1 year of follow-up. Before the campaign, 55% answered correctly to 6 or more out of 10 knowledge items. Knowledge was positively associated with educational level. After the campaign, an increase in knowledge was observed in participants with low levels of education.

CONCLUSIONS

Chinese migrants could be reached with an outreach campaign, and on-site testing was well accepted. A high prevalence of chronic HBV infection was found and referral to specialist care and initiation of treatment was successful.
