Long term outcome of a community-based hepatitis B awareness campaign: eight-year follow-up on linkage to care (LTC) in HBV infected individuals

Background

Chronic hepatitis B (CHB) is a major cause of liver-related morbidity and mortality. High HBV prevalence in immigrants and ethnic minorities and numerous barriers to healthcare access are associated with serious health disparities in the United States. Reportedly, self-awareness of HBV infection is low, suggesting a greater need for effective screening and education. Further, low levels of linkage to care (LTC) (completion of a first doctor’s visit after the diagnosis of chronic HBV infection) may be responsible for the lack of engagement over the continuum of care and for needed services.

Methods

Demographics and survey data were obtained from 97 Korean American adults chronically infected with HBV, initially identified through a series of community screening events in northern New Jersey between Dec. 2009 and June 2015. Eight year follow-up on these HBV-infected individuals was obtained to determine their access to care, and thus the efficacy of a campaign to improve LTC. The participants’ self-awareness of HBV infection and other factors for LTC were also evaluated.

Results

Of a total of 97 HBV-infected participants (age range 30 to 79), 74 were aware of their infections at screening. The remaining 23 had been unaware of their infections until screening. Eight years after the campaign, some 66 of these 97 individuals accessed care (LTC rate 68%). Health insurance status, presence or absence of symptoms and level of knowledge of CHB were among the most significant factors in LTC.

Conclusion

A community-based hepatitis B screening and education campaign can be instrumental in prompting HBV infected individuals to access care, as demonstrated in the cumulative increase in LTC in our cohort. Despite many years of awareness of HBV infection, many are not accessing care owing to a lack of health insurance, suggesting a pressing need for advocacy and health education to improve access to affordable coverage in the Asian American population. Community efforts and strategies similar to the ones employed in the current study may serve as a model to improve the engagement of HBV-infected individuals in high risk immigrant populations.

Knowledge, Awareness, and Prevention of Hepatitis B Virus Infection Among Korean American Parents

Hepatitis B (HB) affects 240 million people around the world, and children and young adults make up a large proportion of the infected population. Approximately 1 million people die from HB each year. Despite the seriousness of HB and its complications, many are poorly linked to clinical care. A lack of health literacy may be a critical barrier hindering access to HB care for adults as well as children in these populations. We, therefore, performed a survey to assess the level of knowledge of HB among Korean American parents. The survey was conducted on 521 Korean American adults who attended community-based HB awareness campaigns held at various locations throughout the metropolitan New York area between January 2015 and November 2016. Of these, 296 parents, who had children between ages 1 and 30, were identified. All participants were asked a series of questions regarding various aspects of HB and were evaluated on the basis of their awareness on each subject. A separate questionnaire was also employed to obtain demographic characteristics of the participants. The study revealed a significant deficit of knowledge of HB in most aspects the survey evaluated. Although the majority of the participants knew that HB is a liver disease, and many of them had been screened for HB, they had a poor understanding of vaccination, screening, their own HB status, modes of HBV transmission, and the consequences and treatment of HB. The participants also had a low level of awareness of their own children’s HB status. This study demonstrates a low level of knowledge of HB among Korean American parents electing to attend a hepatitis education program. In addition, many parents are not aware of their children’s screening and immune (or non-immune) status. The lack of health literacy may contribute to poor health access in HB care, not only in adults but also in children. This suggests an urgent need for education on HB in Korean American parents as well as in young children.

Chronic hepatitis B in Korean Americans: decreased prevalence and poor linkage to care

Background

Chronic hepatitis B virus(HBV) infection is a major cause of liver related morbidity and mortality. HBV infection remains largely underdiagnosed in Asian American population, and it is also poorly linked to clinical care. We, therefore, assessed the HBV prevalence and evaluated linkage to care among Korean Americans in order to develop strategic plans to reduce the impact of HBV in a high risk community.

Methods

Serologic screening and survey were provided to 7157 Korean American adults (age 21–100) in New Jersey between December 2009 and June 2015. All participants were tested for hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core IgG antibody (anti-HBc). Additional survey was conducted on the subjects chronically infected with HBV on their history of infection. Self-administered questionnaires were employed to evaluate demographic and epidemiologic characteristics.

Results

Of those 7157screened, 171 (2.4 %) were HBV infected, 2736(38.2 %) were susceptible to HBV, and 4250(59.4 %) were immune. The prevalence of chronic HBV varied between the age groups: 1.18 % (age21-30); 2.53 % (age 31–40); 2.76 % (age 41–50); 2.90 % (age 51–60); 2.06 % (age 61–70); and 1.37 % (age 71–100). The rate of HBsAg was significantly higher in males (3.04 %) as compared to females (1.93 %). At least 75 % of these HBV infected subjects had been previously diagnosed, but were not engaged in care.

Conclusion

This screening study suggests that the HBV prevalence in Korean Americans is significantly lower than currently understood. On the other hand, many of the individuals chronically infected with HBV cannot access care, suggesting a poor linkage-to-care (LTC). Further, a large percentage of the population is still susceptible to HBV. Study findings will be used to develop strategies to tailor community-based HBV screenings and LTC to the high risk populations.

A community- based hepatitis B linkage-to-care program: a case study on Asian Americans chronically infected with hepatitis B virus

Background

Hepatitis B is an important disease of ethnic disparity which affects Asian Americans and other minority populations disproportionately. Despite the high prevalence of hepatitis B in Asian Americans, many of them remain unscreened and untreated. A majority of the individuals chronically infected with hepatitis B virus (HBV) are not linked to care, for instance, due to a lack of culturally competent programs. There are many serious barriers preventing linkage to care (LTC), including personal, socio-cultural, and economic issues. The purpose of this study was to evaluate various barriers affecting LTC and to investigate the role and efficacy of a community-based Patient Navigator (PN) program in expediting LTC and in improving health outcomes for hepatitis B patients in a high risk population.

Methods

A total of 45 individuals chronically infected with HBV were identified through community screening events and were subsequently linked to patient navigators (PN), who then arranged for the patients to have a medical evaluation with a provider of their choice in their communities. The navigators kept detailed records of the patients’ progress towards goal, and planned follow up visits for each patient. A self-report questionnaire was employed to assess patients’ demographics, history of HBV infection, and barriers in accessing health care. Specifically, the levels of importance of the barriers due to language, culture, financial reasons were assessed.

Results

The study revealed that 38 of the 45 HBV infected individuals knew about their infection status from previous screening. Forty two out of 45 HBV infected individuals were linked to care within a 12 month period, demonstrating a high linkage rate. Most significant barriers identified were language and finance, followed by cultural barrier and others.

Conclusion

There are specific barriers to accessing adequate care for the patients affected by chronic hepatitis B (CHB) in Korean American community. The implementation of a PN program in conjunction with the community network of health care providers may help to overcome the barriers and facilitate LTC in hepatitis B.

Knowledge and fears among Asian Americans chronically infected with hepatitis B

Asian Americans are disproportionately affected by hepatitis B (HBV) infection. In the USA, one in ten Asian Americans is infected with HBV. The purpose of the study was to explore knowledge, fears and follow-up care among Asian Americans chronically infected with hepatitis B. A sample of 154 completed an online survey which included demographic information, follow-up treatment information, and HBV knowledge and fears/concerns. Our findings indicate that there are differences by ethnicity and birthplace among Asian Americans in terms of follow-up care and treatment. In addition, our study indicates that there were substantial knowledge gaps regarding contracting HBV, transmission, and prevention. We found that HBV-infected respondents had many fears about their infection. Three primary concerns were identified: (a) concerns related to liver cancer and overall health, (b) transmission to loved ones, and (c) stigma. Our findings indicate that Asian Americans chronically infected with HBV need more education to manage HBV including information on the importance of follow-up treatment and care and education on preventing transmission, risk for liver cancer, and HBV impact on overall health.

San Francisco hep B free: a grassroots community coalition to prevent hepatitis B and liver cancer

Chronic hepatitis B is the leading cause of liver cancer and the largest health disparity between Asian/Pacific Islanders (APIs) and the general US population. The Hep B Free model was launched to eliminate hepatitis B infection by increasing hepatitis B awareness, testing, vaccination, and treatment among APIs by building a broad, community-wide coalition. The San Francisco Hep B Free campaign is a diverse public/private collaboration unifying the API community, health care system, policy makers, businesses, and the general public in San Francisco, California. Mass-media and grassroots messaging raised citywide awareness of hepatitis B and promoted use of the existing health care system for hepatitis B screening and follow-up. Coalition partners reported semi-annually on activities, resources utilized, and system changes instituted. From 2007 to 2009, over 150 organizations contributed approximately $1,000,000 in resources to the San Francisco Hep B Free campaign. 40 educational events reached 1,100 healthcare providers, and 50% of primary care physicians pledged to screen APIs routinely for hepatitis B. Community events and fairs reached over 200,000 members of the general public. Of 3,315 API clients tested at stand-alone screening sites created by the campaign, 6.5% were found to be chronically infected and referred to follow-up care. A grassroots coalition that develops strong partnerships with diverse organizations can use existing resources to successfully increase public and healthcare provider awareness about hepatitis B among APIs, promote routine hepatitis B testing and vaccination as part of standard primary care, and ensure access to treatment for chronically infected individuals.

Disparities in hepatocellular carcinoma survival among Californians of Asian ancestry, 1988 to 2007

BACKGROUND

Hepatocellular carcinoma (HCC) represents a significant health disparity affecting Asian Americans, a population comprised of distinct ethnic groups. The purpose of this article is to analyze Californians of Asian ancestry with HCC with respect to socioeconomic status, demographic factors, stage of disease, treatment received, and survival.

METHODS

To investigate ethnic differences in survival, we analyzed ethnically disaggregated data from 6,068 Californians of Asian ancestry with HCC diagnosed in 1988 to 2007 and reported to the California Cancer Registry.

RESULTS

Compared with the average of all ethnic groups, cause-specific mortality was significantly higher among Laotian/Hmong [hazard ratio, 2.08; 95% confidence interval (95% CI), 1.78-2.44] and Cambodian patients (hazard ratio, 1.26; 95% CI, 1.06-1.51), groups with higher proportions of their populations at low levels of socioeconomic status; in addition, Laotian/Hmong patients disproportionately presented at later stages of disease, with only 3% receiving local surgical treatment, resection, or liver transplantation. After adjustment for time of diagnosis, age at diagnosis, gender, geographic region, stage at diagnosis, type of surgery, and socioeconomic status, survival disparities remained for both groups (Laotian/Hmong hazard ratio, 1.51; 95% CI, 1.28-1.79; Cambodian hazard ratio, 1.24; 95% CI, 1.03-1.48).

CONCLUSIONS

Our hypothesis that survival outcomes would differ by ethnicity was verified.

IMPACT

Research is needed not only to develop more effective treatments for HCC but also to develop community-based interventions to recruit Asian Americans, particularly Laotian/Hmong and Cambodians, for hepatitis B screening and into medical management to prevent or detect this tumor at an early stage.
