Increasing hepatitis B screening for hmong adults: results from a randomized controlled community-based study

Facilitators and barriers to accessing hepatitis B care in the postpartum period among foreign-born New Yorkers: a qualitative analysis of case notes

BACKGROUND

Approximately 241,000 people are living with hepatitis B in New York City. Among those living with hepatitis B, pregnant people are particularly at risk for elevated viral load due to changes in immune response and require prompt linkage to health care. The New York City Department of Health and Mental Hygiene's Viral Hepatitis Program implemented a telephone-based patient navigation intervention for people living with hepatitis B in the postpartum period to connect them with hepatitis B care.

METHODS

During the intervention, patient navigators called participants to inquire about their past experience with receiving care, available supports, and barriers to care, and worked with them to develop a plan with participants for linkage to hepatitis B care. The information collected during initial assessments and follow-up interactions were recorded as case notes. In this qualitative study, researchers conducted a thematic analysis of 102 sets of case notes to examine facilitators and barriers to accessing hepatitis B care among the intervention participants, all of whom were foreign-born and interested in receiving hepatitis B patient navigation services.

RESULTS

The qualitative analysis illustrated the various ways in which patient navigators supported access to hepatitis B care. Findings suggest that receiving care through a preferred provider was a central factor in accessing care, even in the presence of significant barriers such as loss of health insurance and lack of childcare during appointments. Expectations among family members about hepatitis B screening, vaccination and routine clinical follow up were also identified as a facilitator that contributed to participants' own care.

CONCLUSIONS

This study suggests that while there are numerous barriers at the personal and systemic levels, this patient navigation intervention along with the identified facilitators supported people in accessing hepatitis B care. Other patient navigation initiatives can incorporate the lessons from this analysis to support people in connecting to a preferred provider.

Characterizing asset-based studies in public health: development of a framework

Asset-based approaches are becoming more common within public health interventions; however, due to variations in terminology, it can be difficult to identify asset-based approaches. The study aimed to develop and test a framework that could distinguish between asset-based and deficit-based community studies, whilst acknowledging there is a continuum of approaches. Literature about asset-based and deficit-based approaches were reviewed and a framework was developed based on the Theory of Change model. A scoring system was developed for each of the five elements in the framework based on this model. Measurement of community engagement was built in, and a way of capturing how much the study involved an asset approach. The framework was tested on 13 studies examining community-based interventions to investigate whether it could characterize asset-based versus deficit-based studies. The framework demonstrated how much the principles underpinning asset-based approaches were present and distinguished between studies where the approach was deficit-based to those that had some elements of an asset-based approach. This framework is useful for researchers and policymakers when determining how much of an intervention is asset-based and identifying which elements of asset-based approaches lead to an intervention working.

A training for health care workers to integrate hepatitis B care and treatment into routine HIV care in a high HBV burden, poorly resourced region of Uganda: the '2for1' project

INTRODUCTION

The "2for1" project is a demonstration project to examine the feasibility and effectiveness of HBV care integrated into an HIV clinic and service. An initial phase in implementation of this project was the development of a specific training program. Our objective was to describe key features of this integrated training curriculum and evaluation of its impact in the initial cohort of health care workers (HCWs).

METHODS

A training curriculum was designed by experts through literature review and expert opinion. Key distinctive features of this training program (compared to standard HBV training provided in the Government program) were; (i) Comparison of commonalities between HIV and HBV (ii) Available clinic- and community-level infrastructure, and the need to strengthen HBV care through integration (iii) Planning and coordination of sustained service integration. The training was aided by a power-point guided presentation, question and answer session and discussion, facilitated by physicians and hepatologists with expertise in viral hepatitis. Assessment approach used a self-administered questionnaire among a cohort of HCWs from 2 health facilities to answer questions on demographic information, knowledge and attitudes related to HBV and its prevention, before and after the training. Knowledge scores were generated and compared using paired t- tests.

RESULTS

A training curriculum was developed and delivered to a cohort of 44 HCWs including medical and nursing staff from the two project sites. Of the 44 participants, 20 (45.5%) were male, average age (SD) was 34.3 (8.3) with an age range of 22-58 years. More than half (24, 54.5%) had been in service for fewer than 5 years. Mean correct knowledge scores increased across three knowledge domains (HBV epidemiology and transmission, natural history and treatment) post-intervention. However, knowledge related to diagnosis and prevention of HBV did not change.

CONCLUSION

A structured HBV education intervention conducted as part of an HIV/HBV care integration training for health care workers yielded improved knowledge on HBV and identified aspects that require further training. This approach may be replicated in other settings, as a public health strategy to heighten HBV elimination efforts.

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 media intervention on hepatitis B screening among Vietnamese Americans

Objective: There is a lack of controlled studies of community-wide interventions to increase screening for hepatitis B (HBV) among Asian Americans, particularly Vietnamese Americans, who disproportionately suffer from HBV-related illnesses. The objective of our study was to develop, implement, and evaluate the effectiveness of a media campaign to promote HBV screening among Vietnamese Americans.Design: We designed and implemented a three-year media campaign promoting HBV screening among Vietnamese Americans. Evaluation consisted of cross-sectional pre- and post-intervention population-based telephone surveys of Vietnamese Americans adults age 18-64 who spoke English or Vietnamese and lived in the Northern California (intervention) or Greater Washington, D.C. (comparison) communities in 2007 or 2011. Statistical analysis was completed in 2012. The main outcome was self-report of HBV testing, defined as participants answering 'Yes' to the question: 'Have you ever had a blood test to check for hepatitis B?'Results: The sample sizes at pre- and post-intervention were 1,704 and 1,666, respectively. Both communities reported increased exposure to HBV-related booklets, radio and television advertisements, and websites. Only the intervention community reported increased exposure to newspaper elements. HBV screening increased in both communities (intervention: 65.3% to 73.1%, p < 0.01, comparison: 57.7% to 66.0%, p < 0.01). In multivariable analyses, there was no intervention effect. In both communities, exposure to media elements (Odds Ratio 1.26 [95% Confidence Interval: 1.21, 1.31] for each additional element) was significantly associated with screening.Conclusions: Among Vietnamese Americans in 2 large communities, HBV screening rates were sub-optimal. Screening increased in both the intensive media intervention and comparison communities, and exposure to HBV-related media messages was associated with increased screening. Efforts to address HBV screening among Vietnamese Americans should include mass media messaging.

Prevalence of HBV Infection, Vaccine-Induced Immunity, and Susceptibility Among At-Risk Populations: US Households, 2013-2018

BACKGROUND AND AIMS

In the USA, HBV is one of the leading causes of chronic liver disease and cirrhosis and is a major cause of liver cancer. We aimed to estimate the prevalence of past and present HBV infection, susceptibility to HBV infection, and vaccine-induced immunity to hepatitis B among the US population during 2013-2018.

APPROACH AND RESULTS

Prevalence estimates and 95% CIs were analyzed using 2013-2018 data from the National Health and Nutrition Examination Survey. Serologic testing among noninstitutionalized persons aged ≥ 6 years was used for classifying persons as total hepatitis B core antibody (anti-HBc), indicative of current or previous (ever having had) HBV infection; HBsAg, indicative of current HBV infection; and antibody to ABsAg (anti-HBs), indicative of immunity attributable to hepatitis B vaccination. Persons who tested negative for anti-HBc, HBsAg, and anti-HBs were considered susceptible to HBV infection. Non-US-born residents accounted for 69.1% of the population with chronic HBV infection and were 9.1 times more likely to be living with chronic hepatitis B, compared with US-born persons. Among adults aged ≥ 25 years who resided in US households, an estimated 155.8 million persons (or 73.4%) were susceptible to HBV infection, and an estimated 45.4 million had vaccine-induced immunity to hepatitis B. Men who have sex with men (MSM) were 3.6 times more likely to have ever been infected with HBV; however, MSM were just as likely to have vaccine-induced immunity to hepatitis B as non-MSM.

CONCLUSION

Despite increasing immune protection among young persons vaccinated after birth, the estimated prevalence of persons living with chronic hepatitis B in the USA has remained unchanged at 0.3% since 1999.

Assessing the feasibility, acceptability and impacts of an education program on hepatitis B testing uptake among ethnic Chinese in Australia: results of a randomised controlled pilot study

Background

In Australia, Chinese migrants are among the populations most affected by hepatitis B virus (HBV) infection but often experience late diagnosis or access to clinical care. This study aims to explore approaches to increase HBV testing in Australia’s Chinese community and inform evaluation planning, specifically to i) assess the feasibility and acceptability of HBV educational programs, and ii) compare HBV testing uptake in people receiving a tailored education resource focussing on liver cancer prevention compared with a standard HBV education package.

Methods

This is a pre-post mixed-methods pilot and feasibility study. People of Chinese ethnicity and unsure of their HBV infection or immunity status were recruited from ten community sites in Melbourne, Australia in 2019–2020. Participants were randomised to receive an education package (comprised of a leaflet and in-person one-on-one educational session) with a focus on either 1) standard HBV-related information, or 2) liver cancer prevention. Participants completed a baseline questionnaire prior to receiving the intervention and were followed up at 6 months’ time for a questionnaire and an opt-in semi-structured interview. Primary study outcomes included feasibility of study procedures, measured by recruitment, participation, and retention rates; acceptability of the education program assessed by acceptability scores; and HBV testing uptake rate in each arm. Secondary outcomes include HBV-related knowledge change, assessed by pre-post comparison; and factors affecting participants’ testing behaviour analysed using qualitative data.

Results

Fifty-four participants received an education package; baseline and follow-up data from 33 (61%) were available. The study procedures of recruitment and retention were feasible; the acceptability of the education program was moderate with improved HBV-related knowledge observed. Four participants self-reported being tested: one (1/15, 7%) in the standard HBV information group and three (3/18, 17%) in the liver cancer prevention information group. Factors identified as affecting testing included perceived relevance and seriousness of HBV, healthcare access and costs of testing, and perceptions of the role of primary care providers in HBV-related care.

Conclusion

A tailored education program targeting ethnic Chinese in Australia was feasible with moderate acceptability. A larger study is required to determine if a liver cancer prevention message would improve HBV testing uptake in Chinese community than standard HBV education message. Supports from healthcare providers, community-based testing programs, and public health education programs are likely needed to motivate diagnostic testing among Chinese people at risk of HBV infection.

Prevalence and Susceptibility to Hepatitis B virus and the Need for Community Health Education in Milwaukee's Hmong Community

BACKGROUND

Chronic Hepatitis B virus infection, the leading cause of hepatocellular carcinoma worldwide, disproportionately affects Asian Pacific Islanders (APIs) within the USA. Among APIs, the Hmong have one of the highest rates of chronic HBV infection-up to 18% compared to 0.1% for non-Hispanic Caucasians. This study sought to estimate the prevalence of HBV infection and assess the need for community HBV education within Milwaukee County's Hmong.

METHODS

Between 3/2013 and 12/2019, 287 Hmong participants were screened for HBV and 271 were provided targeted HBV education to evaluate its impact on HBV knowledge.

RESULTS

Among participants screened, 178 (62%) were immune; 77 (27%) susceptible; 27 (9%) positive; and 5 (2%) in a "gray zone." Targeted health education showed statistically significant improvement in HBV knowledge.

DISCUSSION

With 38% lacking immunity to HBV and 9% with active infection, there remains a significant need for HBV screening, vaccination, and education in Milwaukee's Hmong community.

Evidence and gaps in the literature on HIV/STI prevention interventions targeting migrants in receiving countries: a scoping review

BACKGROUND

Evidence suggests that migration increases vulnerability to human immunodeficiency virus (HIV) and other sexually transmitted infections (STI). However, there is limited knowledge about what has been done or needs to be done to address migrants' vulnerability in receiving countries.

OBJECTIVES

A scoping review was carried out to map the existing literature in this field, describe its characteristics, identify gaps in knowledge and determine whether a Sexual and Reproductive Health and Rights (SRHR)-perspective was applied.

METHODS

We used the Arksey and O'Malley framework and the Joanna Briggs Institute guidelines for scoping reviews and subsequent enhancements proposed by other authors. We searched three databases and grey literature to identify relevant publications.

RESULTS

A total of 1,147 records were found across the three electronic databases and compiled. Of these, only 29 papers that met the inclusion criteria were included. The review shows that research in this field is dominated by studies from the USA that mostly include behavioural interventions for HIV and HBV prevention among migrants from Latin America and Asian countries, respectively. None of the interventions integrated an SRHR perspective. The intervention effects varied across studies and measured outcomes. The observed effects on knowledge, attitudes, perceptions, behavioural intentions and skills were largely positive, but reported effects on testing and sexual risk behaviours were inconsistent.

CONCLUSIONS

There is a need for good quality research, particularly in parts of the world other than the USA that will address all STIs and specifically target the most vulnerable subgroups of migrants. Further research requires greater scope and depth, including the need to apply an SRHR perspective and incorporate biomedical and structural interventions to address the interacting causes of migrants' vulnerability to HIV/STIs.

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.

Factors associated with colorectal cancer screening in a peer-counseling intervention study in partnership with African American churches

Colorectal cancer (CRC) mortality is 47% higher in African American men and 34% higher in African American women compared to non-Hispanic white men and women. This analysis assessed factors associated with CRC screening among 163 African American participants of a peer-counseling intervention study (2016-2018). In a one-group pre/post-test pilot study, trained Community Health Advisors (CHAs) at 9 African American churches in Los Angeles (LA) promoted CRC screening via one-on-one counseling, print materials and telephone reminder calls. Participants completed telephone surveys 3-6 months after the intervention. We fit bivariate and multivariate mixed effects logistic regression models to assess correlates, including participants' demographic characteristics, access to care, cancer-related knowledge and attitudes and receipt of CHA counseling of (1) discussion of CRC screening with provider and (2) receipt of CRC screening during follow-up. After controlling for gender and education, receipt of CHA counseling (OR 3.77) was significantly associated with discussing CRC screening with a provider during follow-up but not with CRC screening. Instead, a routine check-up in the past 12 months (OR 4.47) and discussion of CRC screening with a provider (OR 3.07) were significantly associated with CRC screening during follow-up. Residence in South LA (OR 0.38) was significantly associated with lack of CRC screening. Findings confirm the important role of health care providers and suggest that residence in South LA constitutes an additional barrier to CRC screening. Further research and additional resources are needed to address disparities in the uptake of CRC screening among African Americans, especially in South LA.

Review of Hmong-Related Health Problems: A Quick Guide for Healthcare Providers

The people of Hmong descent are one of the largest resettled communities in the United States (US). The Central Valley of California is well known to be the home to the largest Hmong population in the US. However, despite the presence of such a large Hmong community in the Central Valley, our knowledge of their cultural perceptions of medicine is limited. Based on local Central Valley health providers’ experiences and observations, the Hmong people have a number of health-related challenges that differ from those of the general population, and this should be considered when dealing with their healthcare needs. In this report, we present a quick guide about the Hmong community and their health-related issues. We hope this will help clinicians and researchers better understand the Hmong community, which in turn would help provide a better quality of healthcare to the Hmong people and stimulate intellectual curiosity among healthcare providers towards this unique Asian ethnicity.

A crowdsourced intervention to promote hepatitis B and C testing among men who have sex with men in China: A nationwide online randomized controlled trial

BACKGROUND

Crowdsourcing may be an effective strategy to develop test promotion materials. We conducted an online randomized controlled trial (RCT) to evaluate a crowdsourced intervention to promote hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among men who have sex with men (MSM) in China.

METHODS

MSM never previously tested for hepatitis were recruited through social media. Eligible men were randomized to receive an online crowdsourced intervention or no testing promotion materials. Outcomes including self-reported and confirmed HBV and HCV test uptake were assessed after four weeks. Odds ratios (OR) with 95% confidence intervals (95% CI) of men achieving primary and secondary outcomes between the intervention and control arms were calculated.

FINDINGS

556 eligible men were enrolled. Overall, 17•4% (97/556) of men self-reported HBV and HCV testing and 7•9% (44/556) confirmed HBV and HCV test uptake. The intervention was seen by 72•1% and 29•0% of men in the intervention and control arms, respectively. In intention-to-treat analysis, confirmed HBV and HCV test uptake was similar between the two arms, both when using a missing=failure approach (OR 0•98, 95% CI 0•53-1•82) or multiple imputation (OR 1•46, 95% CI 0•72-2•95).

INTERPRETATION

This RCT extends the literature by developing and evaluating an intervention to spur hepatitis testing in a middle-income country with a high burden of hepatitis. Overall test uptake among MSM in China was similar to previous interventions promoting hepatitis testing in high-income countries. We found frequent intervention sharing, complicating interpretation of the results, and the role of crowdsourcing to promote hepatitis testing remains unclear.

The Asian American Network for Cancer Awareness, Research, and Training (AANCART)'s contributions toward reducing Asian American cancer health disparities, 2000-2017

BACKGROUND

In 2000 and in 2 subsequent 5-year cycles, the National Cancer Institute funded grantees on a regional and national basis to address community needs for cancer awareness, research, and training. The Asian American Network for Cancer Awareness, Research and Training (AANCART) is fortunate to have been funded since 2000 to focus on mitigating cancer health disparities facing Asian Americans residing primarily in California and Hawaii. This article highlights AANCART's achievements with respect to the original specific aims and unanticipated outcomes in its most recent funded cycle.

METHODS

Sources included reports to the National Cancer Institute and peer-reviewed articles as well as the insights of the 3 principal investigators.

RESULTS

All aims of the original application (infrastructure, outreach, research, and training) were attained or exceeded. Most distinctive was the completion and publication of 8 randomized controlled trials to address Asian American cancer health disparities and its nurture of 14 new and early stage investigators who have been productive in terms of research career trajectories.

CONCLUSIONS

AANCART is contributing to mitigating Asian American cancer health disparities by catalyzing academic and community collaborations that have resulted in linguistically specific and culturally tailored educational products, scientifically rigorous interventions addressed at cancer risk factors, and nurturing new and early stage Asian American cancer investigators.

Time, trust, and transparency: Lessons learned from collecting blood biospecimens for cancer research from the Asian American community

BACKGROUND

Biospecimens from racially diverse groups are needed to advance cancer research. The Asian American Cancer Education Study was developed to increase the number and proportion of blood biospecimen donations from Asian Americans for cancer research.

METHODS

The authors' targeted approach included 2 types of community engagement, in-reach (within institution to Asian American patients with cancer) and outreach (external to institution to the general Asian American community). Participants received in-language biospecimen education followed by the opportunity to donate blood biospecimens. Outreach participants donated through our community biospecimen blood drives, and in-reach participants consented to donating an extra tube of blood during their routine blood draws as a patient. Donated blood biospecimens were spun down to serum and plasma to be stored in a biorepository or were sent to the laboratory to test for cancer-related risk factors.

RESULTS

Three hundred eighty-eight Asian Americans donated 1127 blood biospecimens for cancer research. Four hundred twenty tubes of plasma and serum are currently being stored at the cancer center's biorepository, 39 tubes have been used for cancer genomic research, and 668 tubes were used to characterize cancer-related risk factors.

CONCLUSIONS

Building upon the past decade of the National Cancer Institute-funded Asian American Network for Cancer Awareness, Research, and Training's foundation of trust and service among Asian Americans, researchers were able to leverage relationships not only to introduce the idea of biospecimen contribution to the community but to also exceed expectations with regard to the quantity of blood biospecimens collected from Asian Americans.

Social-cultural, traditional beliefs, and health system barriers of hepatitis B screening among Hmong Americans: A case study

BACKGROUND

The incidence of liver cancer in Hmong Americans is 5 times higher than that of non-Hispanic whites, and there is a low hepatitis B screening rate (24%) among Hmong adults compared with other Asian American populations. The purpose of this study was to examine the Hmong's perceptions on social-cultural determinants, traditional health beliefs, and health care system barriers that influenced community-based hepatitis B screening interventions.

METHODS

A qualitative method was used, integrating a collective case study research design. In-depth interviews were used to collect data from 20 Hmong adults from the greater Sacramento area. A pattern matching analytic technique was used to analyze the data. The main core elements of Culture Care Theory were used to capture the key themes presented by the participants.

RESULTS

Protecting a family's reputation; fear of doctors, medical procedures, and test results; lack of trust in medical doctors and medical care services; and using Hmong herbal medicines and practicing spiritual healing were identified as social-cultural and traditional health belief barriers to obtaining HBV screening. Health care costs, perceived discrimination, lack of transportation, linguistic discordance, and poor quality of care were identified as barriers to accessing high-quality health care services and obtaining hepatitis B screening.

CONCLUSION

Providers, health policy makers, researchers, and community-based organizations will need to work together to develop intervention strategies to address the social-cultural factors, traditional health beliefs, and health care challenges that influence obtaining hepatitis B screening in the Hmong community.

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.

The efficacy and cost-effectiveness of patient navigation programs across the cancer continuum: A systematic review

Published studies regarding patient navigation (PN) and cancer were reviewed to assess quality, determine gaps, and identify avenues for future research. The PubMed and EMBASE databases were searched for studies investigating the efficacy and cost-effectiveness of PN across the cancer continuum. Each included article was scored independently by 2 separate reviewers with the Quality Assessment Tool for Quantitative Studies. The current review identified 113 published articles that assessed PN and cancer care, between August 1, 2010, and February 1, 2018, 14 of which reported on the cost-effectiveness of PN programs. Most publications focused on the effectiveness of PN in screening (50%) and diagnosis (27%) along the continuum of cancer care. Many described the effectiveness of PN for breast cancer (52%) or colorectal cancer outcomes (51%). Most studies reported favorable outcomes for PN programs, including increased uptake of and adherence to cancer screenings, timely diagnostic resolution and follow-up, higher completion rates for cancer therapy, and higher rates of attending medical appointments. Cost-effectiveness studies showed that PN programs yielded financial benefits. Quality assessment showed that 75 of the 113 included articles (65%) had 2 or more weak components. In conclusion, this review indicates numerous gaps within the PN and cancer literature where improvement is needed. For example, more research is needed at other points along the continuum of cancer care outside of screening and diagnosis. In addition, future research into the effectiveness of PN for understudied cancers outside of breast and colorectal cancer is necessary along with an assessment of cost-effectiveness and more rigorous reporting of study designs and results in published articles.

Cultural Appropriateness in Health Communication: A Review and A Revised Framework

A revised framework for cultural appropriateness is offered on the basis of a systematic review of operationalizations in 44 cancer screening interventions for Asian Americans. Studies commonly conveyed the epidemiological bases of the intervention (97.7%) and used the language of the population (95.5%). Less commonly reported were strategies central to health communication: cultural features of the intervention messages (77.3%) and the cultural beliefs and values that the intervention focused on (43.2%). Few used cultural tailoring (4.5%) and none aimed to address acculturation or cultural identity. The theoretical framework most frequently used was the health belief model (27.3%) which does not explain the role of culture. More studies focused on cultural barriers (20.5%) than cultural strengths (9.1%). Our revised framework comprises six cultural appropriateness strategies of cultural identity, linguistic, perceptual features, content, constituent-involving, and socioeconomic context-adaptive. It prioritizes cultural identity to recognize the dynamics within racial ethnic groups and to inform adaptive efforts for cultural appropriateness. It emphasizes examining cultural strengths that can facilitate change, as well as reducing cultural barriers. Future research and action should address the disparities in extant health disparities research in which theory and methods are underdeveloped and underutilized for Asian Americans.

Promising practices for the prevention of liver cancer: a review of the literature and cancer plan activities in the National Comprehensive Cancer Control Program

INTRODUCTION

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are risk factors for hepatocellular carcinoma, a type of primary liver cancer, and are most prevalent in people born 1945-1965. Relatively little information is available for liver cancer prevention, compared to other cancers. In this review, we provide a summary of current promising public health practices for liver cancer prevention from the literature, as well as liver cancer-related initiatives in the National Comprehensive Cancer Control Program (NCCCP).

METHODS

Two types of source materials were analyzed for this review: published literature (2005-present), and current cancer plans from the NCCCP (2005-2022). A search strategy was developed to include a review of several scientific databases. Of the 73 articles identified as potentially eligible, 20 articles were eligible for inclusion in the review. Eligible articles were abstracted using a data abstraction tool. Three independent keyword searches on 65 NCCCP plans were conducted. Keyword searches within each of the plans to identify activities related to liver cancer were conducted. Relevant information was abstracted from the plans and saved in a data table.

RESULTS

Of the 20 eligible articles, 15 articles provided information on interventions related to liver cancer and hepatitis B or hepatitis C prevention. All 15 of the intervention articles were related to hepatitis; 13 were hepatitis B-focused, two were hepatitis C-focused, and 14 focused on Asian/Pacific Islander American populations. The independent keyword search of NCCCP plans produced 46 results for liver, 27 results for hepatitis, and 52 results for alcohol. Two plans included activities related to liver cancer. Twenty-four plans included activities related to hepatitis.

DISCUSSION

A majority of the intervention articles published focused on HBV infection in Asian/Pacific Islander American populations, and a small percentage of NCCCP plans included liver-related content. The findings from this review will inform the development of an Action Plan on liver cancer prevention for the NCCCP, which will assist programs with the adoption and uptake of promising practices for the prevention of liver cancer.

Partnering with insiders: A review of peer models across community-engaged research, education and social care

Within community-engaged research, education and social care, peer models that partner with local "insiders" are increasingly common. Peer models are composed of insider "lay" community members who often share similarities or background with a project's target population. Peers are not academically trained, but work alongside researchers and professionals to carry out specific tasks within a project, or in the truest sense of partnership, peers collaborate throughout the project from start to finish as an equal member of the team. Although peer models are used widely, the literature lacks consistency and clarity. This systematic review of literature used a qualitative thematic synthesis to examine and report how, where and why peer models have been used in research, education and social care. We examined the language and titles used to describe the peers, details of their involvement in community-engaged projects, the setting, content/topic of study, level of engagement and related benefits/outcomes of such models. Focusing on the last 10 years, we conducted a comprehensive literature search twice between September 2016 and June 2017. The search resulted in 814 articles which were assessed for eligibility. Overall, 251 articles met our inclusion criteria and were categorised into three categories: empirical (n = 115); process/descriptive (n = 93); and "about" peers (n = 43). Findings suggest that there is a wide variety of peers, titles and terminology associated with peer models. There is inconsistency in how these models are used and implemented in research studies and projects. The majority of articles used an employment peer model, while only a handful involved peers in all phases of the project. The results of this literature review contribute to understanding the use, development and evolution of peer models. We highlight potential benefits of peer models for peers, their communities and community-engaged work, and we offer recommendations for future implementation of peer models.

Self-reported patient history to assess hepatitis B virus serological status during a large screening campaign

When assessing hepatitis B virus (HBV) status in clinical settings, it is unclear whether self-reports on vaccination history and previous HBV-test results have any diagnostic capacity. Of 3997 participants in a multi-centre HBV-screening study in Paris, France, 1090 were asked questions on their last HBV-test result and vaccination history. Discordance between self-reported history compared with infection status (determined by serology) was calculated for participants claiming ‘negative’, ‘effective vaccine’, ‘past infection’, or ‘chronic infection’ HBV-status. Serological testing revealed that 320 (29.4%) were non-immunised, 576 (52.8%) were vaccinated, 173 (15.9%) had resolved the infection and 21 (1.9%) were hepatitis B surface antigen positive. In total 208/426 (48.8%) participants with a self-reported history of ‘negative’ infection had a discordant serological result, in whom 128 (61.5%) were vaccinated and 74 (35.6%) had resolved infections. A total of 153/599 (25.5%) participants self-reporting ‘effective vaccine’ had a discordant serological result, in whom 100 (65.4%) were non-immunised and 50 (32.7%) were resolved infections. Discordance for declaring ‘past’ or ‘chronic infection’ occurred in 9/55 (16.4%) and 3/10 (30.0%) individuals, respectively. In conclusion, self-reported HBV-status based on participant history is partially inadequate for determining serological HBV-status, especially between negative/vaccinated individuals. More adapted patient education about HBV-status might be helpful for certain key populations.

Interventions to improve the uptake of screening across a range of conditions in Ethnic Minority Groups: a systematic review

BACKGROUND

Screening programmes are well established in cancer, and are now being implemented in other conditions. An effective screening programme leads to early disease detection and improved outcomes but its impact is dependent on the quality of the test and the proportion of the target population participating. A further consideration is that uptake of screening by minority groups is low.

PURPOSE

To determine which interventions have successfully increased screening uptake amongst minorities.

DATA SOURCES

Medline, Cochrane database and the grey literature were searched from 1990 to 1st March 2016.

STUDY SELECTION

Fifty-five English language studies that assessed uptake of screening in any minority population in the country of study aged over 18 years and that included a comparison arm.

DATA EXTRACTION

Independent data extraction was undertaken by two researchers (CK and MP), using a predesigned data extraction form (DEF) which assisted retrieval of the core contents of each study and the organisation of material.

DATA SYNTHESIS

Evidence was organised by screening test and type of intervention. Two authors (CK and MP) extracted data into evidence tables to enable comparison of study characteristics and findings. The heterogeneity of methods precluded a meta-analysis thus results are descriptive. Evidence was also assessed, using the Cochrane Collaboration risk of bias tables.

RESULTS

This systematic review appraises data from international studies on a variety of minority groups, interventions and screening programmes providing a narrative review of their success and limitations.

Efficacy of a community-based participatory and multilevel intervention to enhance hepatitis B virus screening and vaccination in underserved Korean Americans

BACKGROUND

The primary objective of the current study was to evaluate the efficacy of a community-based participatory intervention program in improving hepatitis B virus (HBV) screening and vaccination among Korean Americans who were not previously screened.

METHODS

A cluster randomized trial involving 32 Korean church-based community organizations (1834 participants) was conducted. Sixteen churches were randomly assigned to an HBV screening and vaccination multicomponent intervention condition (972 participants) and 16 were assigned to a general cancer education control condition (862 participants). The main components of the intervention program included interactive group education; patient navigation; and the engagement of health care providers, church leadership, and church members in the medical field. The application of community-based participatory research principles was monitored and evaluated. HBV screening and vaccination rates (self-reported and medical record verification) were assessed at 6-month and 12-month follow-ups, respectively.

RESULTS

The results of the current study demonstrated significant efficacy in the HBV screening rate (92.5% in the intervention group vs 5.5% in the control group), 3-series HBV vaccination completion rate (84% in the intervention group vs 17.6% in the control group), and overall screening and vaccination compliance rate (87% in the intervention group vs 3.8% in the control group). Participants in the intervention group were significantly more likely to receive HBV screening (92.5%) compared with those in the control group (5.5%). In multivariate mixed-effect logistic regression analysis, the odds ratio for an intervention effect on HBV screening was 512.3 after adjusting for cluster effect and other demographic variables. With regard to vaccination rates, of the 332 participants who were screened with no immunity in the intervention group, 308 (92.8%) received at least 1 HBV vaccination, 300 (90.4%) received at least 2 shots, and 279 participants (84%) received all 3 shots.

CONCLUSIONS

A combination of community-based participatory research and a multilevel approach may produce the most optimal results and be essential in producing a considerable effect for enhancing HBV screening and vaccination, particularly for Korean American populations with limited language proficiency and insurance coverage.

Increasing Hepatitis B Testing and Linkage to Care of Foreign-Born Asians, Sacramento, California, 2012-2013

OBJECTIVE

Without medical intervention, about one-quarter of the 1.4-2.2 million Americans chronically infected with the hepatitis B virus (HBV) will die of HBV-associated conditions, including liver failure and hepatocellular carcinoma. We report on a program in Sacramento County, California, that offered HBV screening to at-risk adults, referred infected individuals to care, and vaccinated uninfected adults who were susceptible to HBV infection (i.e., individuals who tested negative for hepatitis B surface antigen and who were never vaccinated against HBV).

METHODS

We engaged organizations linked to Chinese, Hmong, Korean, and Vietnamese communities to cosponsor HBV screenings of Asian Americans as part of the Hepatitis Testing and Linkage to Care initiative, which promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites. We held 28 hepatitis B community screening events throughout Sacramento County, California, in collaboration with these groups from September 2012 to September 2013.

RESULTS

We screened 1,004 Asian American adults (i.e., 283 Koreans, 242 Chinese, 233 Vietnamese, 223 Hmong, and 23 people from other Asian communities) for HBV, of whom 98% were foreign born and 87% had a language preference other than English. Of the 76 participants who tested positive for HBV (31 Hmong, 23 Vietnamese, 17 Chinese, two Koreans, and three from other Asian communities), we provided posttest counseling to 51 participants.

CONCLUSION

By collaborating with community groups and addressing barriers to screening, we highlighted the importance of disaggregating chronic HBV infection rates by Asian ethnicity and sex vs. aggregated Asian American rates. Future HBV screening initiatives should target Hmong and Vietnamese men.

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.

A Community-Based Randomized Trial of Hepatitis B Screening Among High-Risk Vietnamese Americans

OBJECTIVES

To evaluate the effectiveness of a community-based liver cancer prevention program on hepatitis B virus (HBV) screening among low-income, underserved Vietnamese Americans at high risk.

METHODS

We conducted a cluster randomized trial involving 36 Vietnamese community-based organizations and 2337 participants in Pennsylvania, New Jersey, and New York City between 2009 and 2014. We randomly assigned 18 community-based organizations to a community-based multilevel HBV screening intervention (n = 1131). We randomly assigned the remaining 18 community-based organizations to a general cancer education program (n = 1206), which included information about HBV-related liver cancer prevention. We assessed HBV screening rates at 6-month follow-up.

RESULTS

Intervention participants were significantly more likely to have undergone HBV screening (88.1%) than were control group participants (4.6%). In a Cochran-Mantel-Haenszel analysis, the intervention effect on screening outcomes remained statistically significant after adjustment for demographic and health care access variables, including income, having health insurance, having a regular health provider, and English proficiency.

CONCLUSIONS

A community-based, culturally appropriate, multilevel HBV screening intervention effectively increases screening rates in a high-risk, hard-to-reach Vietnamese American population.

The effectiveness of patient navigation to improve healthcare utilization outcomes: A meta-analysis of randomized controlled trials

OBJECTIVE

To determine the effects of patient navigation (PN) on healthcare utilization outcomes using meta-analysis and the quality of evidence.

METHODS

Medical and social science databases were searched for randomized controlled trials published in English between 1989 and May 2015. The review process was guided by PRISMA. Included studies were assessed for quality using the Downs and Black tool. Data were extracted to assess the effect of navigation on: health screening rates, diagnostic resolution, cancer care follow-up treatment adherence, and attendance of care events. Random-effects models were used to compute risk ratios and I² statistics determined the impact of heterogeneity.

RESULTS

Of 3985 articles screened, 25 articles met inclusion criteria. Compared to usual care, patients who received PN were significantly more likely to access health screening (OR 2.48, 95% CI, 1.93-3.18, P<0.00001) and attend a recommended care event (OR 2.55, 95% CI, 1.27-5.10, P<0.01). PN was favoured to increase adherence to cancer care follow-up treatment and obtain diagnoses. Most studies involved trained lay navigators (n=12) compared to health professionals (n=9).

CONCLUSION

PN is effective to increase screening rates and complete care events.

PRACTICE IMPLICATIONS

PN is an effective intervention for use in healthcare.

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.

Do Recommendations by Healthcare Providers, Family-members, Friends, and Individual Self-Efficacy Increase Uptake of Hepatitis B Screening? Results of a Population-Based Study of Asian Americans

BACKGROUND

Hepatitis B virus (HBV) infection disproportionately affects Asian Americans but HBV screening rates among Asian American are substantially low. This study examines the impact of multiple recommendations and self-efficacy on HBV screening uptake among Asian Americans.

METHODS

Data for this study were from 872 Chinese, Korean and Vietnamese recruited for a liver cancer prevention program in the Washington D.C - Baltimore metropolitan area.

RESULTS

410 (47%) respondents reported previous HBV screening. Only 19.8% recalled a physician recommendation. Higher level of HBV screening was reported among people who had physician recommendation, family member recommendation or friend recommendation. Perceived self-efficacy was also an important predictor to HBV screening. The effect of self-efficacy was significant in subgroup analyses among Chinese and Korean, but not for Vietnamese.

CONCLUSION AND GLOBAL HEALTH IMPLICATIONS

The disproportional prevalence of HBV infection among Asian Americans is considered to be one of the most important health disparities for Asian population. Understanding the condition and screening behavior in this population is especially important. Our findings suggest that recommendation from physician and social networks should be encouraged for HBV screening among Asian Americans. Both recommendation and self-efficacy of HBV screening are important psychosocial constructs to be targeted in liver cancer prevention interventions.

Improving Healthcare Systems to Reduce Healthcare Disparities in Viral Hepatitis

Chronic hepatitis B (CHB) and C (CHC) represent significant public health problems worldwide. Combined, over 7 million persons in the USA are chronically infected with either the hepatitis B or the hepatitis C virus. Although the populations affected by the viruses differ, both CHB and CHC are ideal conditions for preventive screening because of a high prevalence and low rate of diagnosis; an early asymptomatic period; highly sensitive and specific test; and treatments which have been shown to result in improved clinical outcomes including liver-related mortality and hepatocellular carcinoma. Improving healthcare delivery for CHB and CHC requires interventions that will increase screening for the infections, expanded capacity for evaluation and monitoring of the infection, and ultimately improved access to treatment. Many of these interventions may leverage opportunities within electronic health records, but must also address unique social, cultural, and language barriers that may prevent effective implementation of novel interventions. Herein, we will review current knowledge related to strategies employed to improve healthcare systems to reduce disparities in viral hepatitis.

Lay Health Worker Intervention Improved Compliance with Hepatitis B Vaccination in Asian Americans: Randomized Controlled Trial

Background

This study aimed to evaluate the effect of a lay health worker (LHW) telephone intervention on completing a series of hepatitis B virus (HBV) vaccinations among foreign-born Asian Americans in the Baltimore-Washington Metropolitan area.

Methods

During the period of April 2013 and March 2014, we recruited Asian Americans who were 18 years of age and older in the community-based organizations. Of the 645 eligible participants, 600 (201 Chinese, 198 Korean, 201 Vietnamese) completed a pretest survey and received hepatitis B screening. Based on the screening results, we conducted a randomized controlled trial among those unprotected (HBsAg-/HBsAB-) by assigning them either to an intervention group (n = 124) or control group (n = 108). The intervention group received a list of resources by mails for where to get free vaccinations as well as reminder calls for vaccinations from trained LHWs, while the control group received only list of resources by mail. Seven months after mailing the HBV screening results, trained LHWs followed up with all participants by phone to ask how many of the recommended series of 3 vaccinations they had received: none, 1 or 2, or all 3 (complete). Their self-reported vaccinations were verified with the medical records. Multinomial logistic regressions were used to examine the effect of the LHW intervention. Process evaluation was conducted by asking study participants in the intervention group to evaluate the performance of the LHWs.

Results

After seven months, those in the intervention group were more likely to have 1 or more vaccines than the control group, compared to the no vaccination group (OR = 3.04, 95% CI, 1.16, 8.00). Also, those in the intervention group were more likely to complete a series of vaccinations than the control group, compared to the no vaccination group (OR = 7.29, 95% CI 3.39, 15.67). The most important barrier preventing them from seeking hepatitis B vaccinations was lack of time to get the vaccination. The most important promoters to getting vaccinations, among those who had vaccinations (n = 89), were our intervention program (70.8%) and self-motivation (49.4%). The majority of participants in the intervention group received the phone calls from LHWs (93%) and almost all of them got the reminder to receive vaccines (98%).

Conclusion

The LHW intervention was successful at increasing HBV vaccinations rates among foreign-born Asian Americans. This study suggests that this culturally integrated intervention program may be useful for reducing liver cancer disparities from chronic HBV infection in high risk Asian Americans.

Interventions to optimise the care continuum for chronic viral hepatitis: a systematic review and meta-analyses

BACKGROUND

Advances in therapy for hepatitis B virus (HBV) and hepatitis C virus (HCV) have ushered in a new era in chronic hepatitis treatment. To maximise the effectiveness of these medicines, individuals must be engaged and retained in care. We analysed operational interventions to enhance chronic viral hepatitis testing, linkage to care, treatment uptake, adherence, and viral suppression or cure.

METHODS

We did a systematic review of operational interventions, and did meta-analyses for sufficiently comparable data. We searched PubMed, Embase, WHO library, International Clinical Trials Registry Platform, PsycINFO, and CINAHL for randomised controlled trials and controlled non-randomised studies that examined operational interventions along the chronic viral hepatitis care continuum, published in English up to Dec 31, 2014. We included non-pharmaceutical intervention studies with primary or secondary outcomes of testing, linkage to care, treatment uptake, treatment adherence, treatment completion, treatment outcome, or viral endpoints. We excluded dissertations and studies of children only. Data were extracted by two independent reviewers, with disagreements resolved by a third reviewer. Studies were assessed for bias. Data from similar interventions were pooled and quality of evidence was assessed using GRADE. This study was registered in PROSPERO (42014015094).

FINDINGS

We identified 7583 unduplicated studies, and included 56 studies that reported outcomes along the care continuum (41 for HCV and 18 for HBV). All studies except one were from high-income countries. Lay health worker HBV test promotion interventions increased HBV testing rates (relative risk [RR] 2·68, 95% CI 1·82-3·93). Clinician reminders to prompt HCV testing during clinical visits increased HCV testing rates (3·70, 1·81-7·57). Nurse-led educational interventions improved HCV treatment completion (1·14, 1·05-1·23) and cure (odds ratio [OR] 1·93, 95% CI 1·44-2·59). Coordinated mental health, substance misuse, and hepatitis treatment services increased HCV treatment uptake (OR 3·03, 1·24-7·37), adherence (RR 1·22, 1·05-1·41), and cure (RR 1·21, 1·07-1·38) compared with usual care.

INTERPRETATION

Several simple, inexpensive operational interventions can substantially improve engagement and retention along the chronic viral hepatitis care continuum. Further operational research to inform scale-up of hepatitis services is needed in low-income and middle-income countries.

Lay health educators increase colorectal cancer screening among Hmong Americans: A cluster randomized controlled trial

BACKGROUND

Asian Americans have lower colorectal cancer (CRC) screening rates than non-Hispanic white individuals. Hmong Americans have limited socioeconomic resources and literacy. The current randomized controlled trial was conducted to determine whether bilingual/bicultural lay health educator (LHE) education could increase CRC screening among Hmong Americans.

METHODS

A cluster randomized controlled trial was conducted among Hmong Americans in Sacramento, California. LHEs and recruited participants were randomized to intervention or control groups. The intervention group received CRC education over 3 months delivered by an LHE. The control group received education regarding nutrition and physical activity delivered by a health educator. The outcomes were changes in self-reported ever-screening and up-to-date CRC screening after 6 months.

RESULTS

All 329 participants were foreign-born with mostly no formal education, limited English proficiency, and no employment. The majority of the participants were insured and had a regular source of health care. The intervention group experienced greater changes after the intervention than the control group for ever-screening (P = .068) and being up-to-date with screening (P<.0001). In multivariable regression analyses, the intervention group demonstrated a greater increase than the control group in reporting ever-screening (adjusted odds ratio, 1.73; 95% confidence interval, 1.07-2.79) and being up-to-date with screening (adjusted odds ratio, 1.71; 95% confidence interval, 1.26-2.32). Individuals who had health insurance were found to have >4 times the odds of receiving screening, both ever-screening and up-to-date screening. A higher CRC knowledge score mediated the intervention effect for both screening outcomes.

CONCLUSIONS

A culturally and linguistically appropriate educational intervention delivered by trained LHEs was found to increase CRC screening in an immigrant population with low levels of education, employment, English proficiency, and literacy. Cancer 2017;98-106. © 2016 American Cancer Society.

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.

Cancer statistics for Asian Americans, Native Hawaiians, and Pacific Islanders, 2016: Converging incidence in males and females

Cancer is the leading cause of death among Asian Americans, Native Hawaiians, and Pacific Islanders (AANHPIs). In this report, the American Cancer Society presents AANHPI cancer incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Among AANHPIs in 2016, there will be an estimated 57,740 new cancer cases and 16,910 cancer deaths. While AANHPIs have 30% to 40% lower incidence and mortality rates than non-Hispanic whites for all cancers combined, risk of stomach and liver cancers is double. The male-to-female incidence rate ratio among AANHPIs declined from 1.43 (95% confidence interval, 1.36-1.49) in 1992 to 1.04 (95% confidence interval, 1.01-1.07) in 2012 because of declining prostate and lung cancer rates in males and increasing breast cancer rates in females. The diversity within the AANHPI population is reflected in the disparate cancer risk by subgroup. For example, the overall incidence rate in Samoan men (526.5 per 100,000) is more than twice that in Asian Indian/Pakistani men (216.8). Variations in cancer rates in AANHPIs are related to differences in behavioral risk factors, use of screening and preventive services, and exposure to cancer-causing infections. Cancer-control strategies include improved use of vaccination and screening; interventions to increase physical activity and reduce excess body weight, tobacco use, and alcohol consumption; and subgroup-level research on burden and risk factors.

Perceptions of Risk for Hepatitis B Infection among the Hmong

The Hmong in the U.S. who emigrated from Southeast Asia, an area where hepatitis B is endemic, experience high rates of hepatitis B infection and liver cancer compared to non-Hispanic whites. This exploratory study examined the Hmong's perceptions of risk of hepatitis B infection. We interviewed 83 Hmong women and men living in Oregon. In bivariate statistical analysis, greater perceived susceptibility, lower perceived barriers, and having a healthcare provider recommendation were each significantly related to having ever been screened for hepatitis B. Logistic regression models indicated that having a recommendation by a doctor or healthcare provider was the strongest predictor of having been screened for hepatitis B, followed by education and insurance. Future interventions with the Hmong population should focus on the important role of health care providers play in raising awareness about hepatitis B infection and increasing screening uptake.

Training in Patient Navigation: A Review of the Research Literature

Despite the proliferation of patient navigation programs designed to increase timely receipt of health care, little is known about the content and delivery of patient navigation training, or best practices in this arena. The current study begins to address these gaps in understanding, as it is the first study to comprehensively review descriptions of patient navigation training in the peer-reviewed research literature. Seventy-five patient navigation efficacy studies published since 1995, identified through PubMed and by the authors, were included in this narrative review. Fifty-nine of the included studies (79%) mentioned patient navigation training, and 55 of these studies additionally provided a description of training. Most studies did not thoroughly document patient navigation training practices. Additionally, several topics integral to the role of patient navigators, as well as components of training central to successful adult learning, were not commonly described in the research literature. Descriptions of training also varied widely across studies in terms of duration, location, format, learning strategies employed, occupation of trainer, and content. These findings demonstrate the need for established standards of navigator training as well as for future research on the optimal delivery and content of patient navigation training.

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.

Characteristics of Asian American, Native Hawaiian, and Pacific Islander community health worker programs: a systematic review

Community health workers (CHWs) are frontline health workers who often serve socially and linguistically isolated populations, including Asian American, Native Hawaiian, and Pacific Islander (AA and NHPI) communities in the United States (U.S.) and U.S. territories. We conducted a systematic review of the peer-reviewed literature to assess the characteristics of CHW programs for AA and NHPI communities in the U.S. and U.S. territories, generating a total of 75 articles. Articles were coded using eight domains: ethnic group, health topic, geographic location, funding mechanism, type of analysis reported, prevention/management focus, CHW role, and CHW title. Articles describing results of an intervention or program evaluation, or cost-effectiveness analysis were further coded with seven domains: study design, intervention recruitment and delivery site, mode of intervention delivery, outcomes assessed, key findings, and positive impact. Results revealed gaps in the current literature and point towards recommendations for future CHW research, program, and policy efforts.

Research challenges and lessons learned from conducting community-based research with the Hmong community

BACKGROUND

Conducting research with underserved communities with little exposure to research presents a number of challenges and opportunities. Our study used a community-based approach to better understand factors that influence breast and cervical cancer screening among Hmong women.

OBJECTIVE

This article shares lessons learned during the process of developing and conducting qualitative research with a Hmong community with limited experience with research.

METHOD

We conducted 17 key informant and 84 in-depth interviews with Hmong women and men. Research team discussions, insights from Hmong research team members, input from our Community Advisory Committee, and project documents were sources of information about the process of conducting research in this community.

RESULTS

Lessons learned concern including a cultural insider as an investigator; building community partnerships and support; establishing and working with a community advisory committee; hiring and training bilingual, bicultural staff; and using culturally appropriate materials and methods in a small, kinship-based community. We used multiple strategies to ensure that this study was conducted in a culturally appropriate manner.

CONCLUSION

The lessons learned from our experiences can provide guidance to researchers on methodological and practical issues in conducting research with the Hmong and can inform future research with the Hmong and other similar underserved populations.

Developing theoretically based and culturally appropriate interventions to promote hepatitis B testing in 4 Asian American populations, 2006-2011

Introduction

Hepatitis B infection is 5 to 12 times more common among Asian Americans than in the general US population and is the leading cause of liver disease and liver cancer among Asians. The purpose of this article is to describe the step-by-step approach that we followed in community-based participatory research projects in 4 Asian American groups, conducted from 2006 through 2011 in California and Washington state to develop theoretically based and culturally appropriate interventions to promote hepatitis B testing. We provide examples to illustrate how intervention messages addressing identical theoretical constructs of the Health Behavior Framework were modified to be culturally appropriate for each community.

Methods

Intervention approaches included mass media in the Vietnamese community, small-group educational sessions at churches in the Korean community, and home visits by lay health workers in the Hmong and Cambodian communities.

Use of the Health Behavior Framework allowed a systematic approach to intervention development across populations, resulting in 4 different culturally appropriate interventions that addressed the same set of theoretical constructs.

Conclusions

The development of theory-based health promotion interventions for different populations will advance our understanding of which constructs are critical to modify specific health behaviors.
