Linkage-to-Care Following Community-Based HBV and HCV Screening Among Immigrants from the Washington–Baltimore Metropolitan Area, 2016–2019

Opportunistic screening using point-of-care testing leads to successful linkage to care of HBV-infected migrant populations in a low endemic country

Background and aims

In low endemic countries, screening for hepatitis B surface antigen (HBsAg) in migrants is cost-effective in reducing the disease burden of hepatitis B virus (HBV) infections, but linkage to care (LTC) remains a challenge. This study aims to guide future screening initiatives, with 3 objectives: 1. to compare LTC between different ethnic groups screened for HBsAg with point-of-care testing (POCT) in an outreach setting; 2. to estimate the proportion of HBsAg seropositivity for ethnic minorities; and 3. to investigate the association between seropositivity and HBV risk factors.

Methods

Opportunistic outreach screenings using finger prick HBsAg tests were performed at civic integration programmes between 11/2017 and 09/2022. If an individual tested positive, an appointment was given immediately at the outpatient hepatology clinic for follow-up and confirmation of HBsAg positivity in blood. Dedicated personnel contacted these individuals to motivate them for further LTC, which was defined as being assessed by a hepatologist, a blood test and an abdominal ultrasound.

Results

A total of 677 people from different ethnicities (Asian, Middle Eastern and African) were serologically screened using POCT. The observed positivity for HBsAg was 3.4 % (95% CI 2.17-5.05, 23/677). Apart from ethnicity and male sex, none of the surveyed HBV risk factors were associated with HBsAg seropositivity. All HBsAg positive individuals were linked to care and assessed by a hepatologist, despite the COVID-19 pandemic increase in time to follow-up of 82 days (95% CI 51-112 days) vs. 24 days (95% CI 5-43 days, p = 0.008)).Among HBV-infected patients, 31.8% (7/22), 100 % (22/22) and 26.1% (6/23) met the criteria for treatment indication, intrafamilial transmission risk and need for hepatocellular carcinoma surveillance, respectively.

Conclusion

The proportion of HBsAg seropositivity in ethnic minorities was 3.4%. POCT and commitment of dedicated personnel can overcome previously identified barriers resulting in a 100% LTC.

Health Service Utilization of Black Immigrant Women Residing in the United States: A Systematic Review

Black immigrants constitute a rapidly growing population group in the U.S. A comprehensive understanding of health services used by Black immigrant women is necessary to support the complex needs of this population. We conducted a systematic review to (1) understand the types of health services used by Black immigrant women living in the U.S. and (2) examine barriers and motivators to using health services. Relevant studies were identified in the following databases: PubMed, PsychInfo, CINAHL, and Embase. Articles published until October 2022 were included in the review. From a total of 15,245 records, 47 articles that reported on health service utilization practices of Black immigrant women were included in the review. A variety of different health services were accessed by Black immigrant women, such as hepatitis screening, reproductive health services, cancer screenings, substance abuse treatment, mental health services, HIV services, dental services, genetic testing, cardiovascular risk testing, and general health services/ hospitalizations. Motivators for using health services included possession of health insurance, knowledge of health resources and conditions, and positive experiences with providers. Barriers to using health services included challenges navigating the health system, language barriers, and cultural beliefs. Factors that positively influence health service utilization must be expanded at the institutional, societal, and policy levels to improve access to health services for Black immigrant women.

A Health Belief Model Examination of Factors Related to Hepatitis B Screening Among African Immigrants in Philadelphia

Chronic hepatitis B infection is a leading cause of liver cancer worldwide. In the USA, African immigrants (AI) have high hepatitis B virus (HBV) infection rates but low HBV knowledge and screening rates. Research about HBV among AI living in Philadelphia is particularly limited. This study aims to assess barriers to and factors influencing HBV screening in the Philadelphia AI population. African and Caribbean-born adults in Greater Philadelphia were recruited for phone interviews at community health fairs hosted by the African Cultural Alliance of North America (ACANA) and the African Family Health Organization (AFAHO) in partnership with the Hepatitis B Foundation. Seventeen interviews were recorded, transcribed, and coded independently by two members of the research team using NVivo software. Themes and subthemes were created by analysis of the codes and arranged under Health Belief Model (HBM) concepts. Major perceived barriers included lack of HBV knowledge and awareness and cultural challenges related to health care access, preventive care, fear, and stigma. Participants recommended using community organizations and programs to spread awareness about HBV and serve as cues to action. In-person education was emphasized due to lack of access to and knowledge of technology such as Zoom. While HBV educational sessions have been implemented in this population, they have not been consistent or far-reaching. The results of this study can contribute to the implementation of a comprehensive AI-specific HBV education and screening program through partnerships with community organizations to ensure that all high-risk individuals in the Philadelphia area are screened.

Process evaluation of an academic-community-government partnership to reduce liver diseases attributable to hepatitis B virus

BACKGROUND

Racial/ethnic minorities have higher incidence and mortality rates of liver cancer, or hepatocellular carcinoma, than non-Hispanic Whites. As such, the Washington-Baltimore Metropolitan Area Hepatitis B Virus (WB-HBV) Demonstration Project, a community-based participatory research (CBPR)-driven academic-community-government (ACG) partnership, was established in 2019 to address disparities and implement strategies to improve the HBV screening and vaccination infrastructure for at-risk communities. CBPR is a partnership of community members, organizational leaders, and academic researchers with a common aim to collectively share and contribute their input at every phase of the project. Herein, we describe the process evaluation of the WB-HBV Project and extract themes and insights to benefit future ACG partnerships and community-engaged research. The process evaluation has been conducted to determine whether CBPR-driven partnership and programmatic activities have been implemented as intended and have resulted in building expanded research capacity for future ACG partnership HBV community-level initiatives.

METHODS

A WB-HBV Project Task Force was convened and comprised of eight organizations: four community organizations, three government organizations, and one academic institution. Through a mixed-methods process evaluation, an online survey and key informant interviews were conducted to provide context for program implementation barriers and facilitators. Descriptive statistics were conducted, and interviews were recorded, transcribed, and thematically coded.

RESULTS

The survey was completed by 14 of 20 partnership members (70.0%): two academic, eight community, and four government members. Partnership members showed general agreement across 14 domains: organization and structure of meetings; trust; decisions; impact; general satisfaction; strategic planning; ACG policy impact; community-based participatory research and government; participation in meetings; assessment of participation; partnership operations and capacity; communication; challenges/limitations associated with ACG involvement; and benefits compared to challenges associated with ACG involvement. Qualitative interviews were conducted with 15 of the 20 members (75.0%): two academic, nine community, and four government members. Four themes emerged: partnership involvement, project goals and accomplishments, project challenges and barriers, and partnership involvement in government or policy.

CONCLUSIONS

The process evaluation presents insights into developing strategies to enhance partnership functioning and increase the ability of present and future ACG partnerships to improve community health outcomes.
