Strategies to reach and motivate migrant communities at high risk for TB to participate in a latent tuberculosis infection screening program: a community-engaged, mixed methods study among Eritreans

Approaches to increase access to community-based infectious disease control for ethnically, racially, and religiously marginalised populations: a scoping review

Marginalised populations often have reduced access to infectious disease prevention interventions, and as a result of this and other socioeconomic factors, these populations are at a higher risk of disease. Here, we reviewed the literature of community-based interventions delivered at the individual level across multiple diseases, and focused on how to increase access to infectious disease interventions for ethnically, racially, and religiously marginalised populations. Most of the included studies only focused on a single disease and used quantitative descriptive methods. We noted the lack of research, especially in low-income and middle-income countries. Common themes on the adaptations made included the importance of trust, descriptions of how the community was engaged at a deep level, and highlighting the importance of where interventions were delivered. We conclude that there is a need for more implementation research on this topic. Understanding how to increase access is crucial for achieving universal health coverage, which is also important from a global health security perspective, especially in an era when large-scale epidemics and pandemics are becoming more common.

High metabolic dysfunction-associated steatotic liver disease prevalence in type 2 diabetes: Urgent need for integrated screening and lifestyle intervention

This letter discusses the recent study by Mukherjee et al, which identifies a significant prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) among newly diagnosed type 2 diabetes mellitus (T2DM) patients in Bihar, India, and underscores the pressing need for integrated MASLD management within T2DM care. With 72.3% of the study cohort affected by MASLD, implementing routine liver function tests and ultrasound screenings is recommended as a standard practice in diabetes care, especially in regions with high prevalence rates. The study also advocates for dietary and lifestyle modifications, particularly the reduction of saturated fats, to slow MASLD progression. Patient education on monitoring body mass index and waist circumference, coupled with the integration of these metrics into digital health records, could enhance patient involvement and support proactive health management. Moreover, the letter emphasizes the advantages of developing a region-specific MASLD risk model that incorporates local dietary patterns and socioeconomic factors. Continued research into genetic and environmental determinants of MASLD remains essential for advancing our understanding of its etiology and informing targeted public health strategies.

Barriers and facilitators of tuberculosis treatment among immigrants: an integrative review

BACKGROUND AND OBJECTIVES

Migration, as an important social determinant in the field of health, plays a crucial role in the non-eradication of tuberculosis worldwide. Therefore, it is essential to identify the factors related to tuberculosis treatment in immigrants to effectively combat this disease. However no comprehensive study has focused on this issue. Therefore, this study was conducted using an ecological approach to identify the barriers and facilitators of tuberculosis treatment in immigrants.

METHODS

This qualitative study utilized an integrative literature review. Studies were searched without time restrictions in database such as MEDLINE, Institute for Scientific Information (ISI), Google Scholar, Scopus, and EMBAS, as well as internal databases like Scientific Information Database and Magiran. The findings of 100 studies that met the inclusion criteria were analyzed using the conventional content analysis method based on the ecological approach.

RESULTS

In general, the aforementioned codes were placed into four main categories, including individual factors (i.e., biological factors, psychological factors, behavioral factors, patient knowledge, factors related to tuberculosis, and economic factors), interpersonal factors (i.e., communication with the treatment team and family-related factors), factors related to health service provider centers (i.e., medical facilities), and extra-organizational factors (i.e., social factors and health policies).

CONCLUSION

The findings of the present study show that treating tuberculosis in immigrants is a complex phenomenon influenced by several factors. Therefore policymakers and healthcare providers should take a more comprehensive look at the factors affecting treatment in this group of patients to plan and implement more effective interventions.

Strengthening Tuberculosis Control Among Migrant Workers

Tuberculosis (TB) is a serious infectious disease accounting for a significant number of deaths due to the infectious nature of the disease on the global platform. Migrant workers need special attention as these population groups live in substandard and crowded environmental conditions with poor ventilation, which play a crucial role in augmenting the risk of acquisition of infection. The global vision to ensure the delivery of effective TB control-related services for migrant workers has been influenced by a wide range of barriers. This issue is further complicated by the limited knowledge of migrant workers about tuberculosis, their rights, the kind of services available in healthcare facilities, and the ways to prevent the acquisition and transmission of infectious disease. By acknowledging the role of predisposing factors and the potential barriers that impact accessing timely healthcare services, it can be seen that the need of the hour is to plan and implement a comprehensive package of services for the benefit of migrant workers.

Treatment of latent tuberculosis infection in migrants in primary care versus secondary care

BACKGROUND

Control of latent tuberculosis infection (LTBI) is a priority in the World Health Organization strategy to eliminate TB. Many high-income, low TB incidence countries have prioritised LTBI screening and treatment in recent migrants. We tested whether a novel model of care, based entirely within primary care, was effective and safe compared to secondary care.

METHODS

This was a pragmatic cluster-randomised, parallel group, superiority trial (ClinicalTrials.gov: NCT03069807) conducted in 34 general practices in London, UK, comparing LTBI treatment in recent migrants in primary care to secondary care. The primary outcome was treatment completion, defined as taking ≥90% of antibiotic doses. Secondary outcomes included treatment acceptance, adherence, adverse effects, patient satisfaction, TB incidence and a cost-effectiveness analysis. Analyses were performed on an intention-to-treat basis.

RESULTS

Between September 2016 and May 2019, 362 recent migrants with LTBI were offered treatment and 276 accepted. Treatment completion was similar in primary and secondary care (82.6% versus 86.0%; adjusted OR (aOR) 0.64, 95% CI 0.31-1.29). There was no difference in drug-induced liver injury between primary and secondary care (0.7% versus 2.3%; aOR 0.29, 95% CI 0.03-2.84). Treatment acceptance was lower in primary care (65.2% (146/224) versus 94.2% (130/138); aOR 0.10, 95% CI 0.03-0.30). The estimated cost per patient completing treatment was lower in primary care, with an incremental saving of GBP 315.27 (95% CI 313.47-317.07).

CONCLUSIONS

The treatment of LTBI in recent migrants within primary care does not result in higher rates of treatment completion but is safe and costs less when compared to secondary care.

Interventions to improve latent and active tuberculosis treatment completion rates in underserved groups in low incidence countries: a scoping review

BACKGROUND

People in underserved groups have higher rates of tuberculosis (TB) and poorer treatment outcomes compared with people with no social risk factors.

OBJECTIVES

This scoping review aimed to identify interventions that improve TB treatment adherence or completion rates.

ELIGIBILITY CRITERIA

Studies of any design focusing on interventions to improve adherence or completion of TB treatment in underserved populations in low incidence countries.

SOURCES OF EVIDENCE

MEDLINE, Embase and Cochrane CENTRAL were searched (January 2015 to December 2023).

CHARTING METHODS

Piloted data extraction forms were used. Findings were tabulated and reported narratively. Formal risk of bias assessment or synthesis was not undertaken.

RESULTS

47 studies were identified. There was substantial heterogeneity in study design, population, intervention components, usual care and definition of completion rates. Most studies were in migrants or refugees, with fewer in populations with other risk factors (eg, homelessness, imprisonment or substance abuse). Based on controlled studies, there was limited evidence to suggest that shorter treatment regimens, video-observed therapy (compared with directly observed therapy), directly observed therapy (compared with self-administered treatment) and approaches that include tailored health or social support beyond TB treatment may lead to improved outcomes. This evidence is mostly observational and subject to confounding. There were no studies in Gypsy, Roma and Traveller populations, or individuals with mental health disorders and only one in sex workers. Barriers to treatment adherence included a lack of knowledge around TB, lack of general health or social support and side effects. Facilitators included health education, trusted relationships between patients and healthcare staff, social support and reduced treatment duration.

CONCLUSIONS

The evidence base is limited, and few controlled studies exist. Further high-quality research in well-defined underserved populations is needed to confirm the limited findings and inform policy and practice in TB management. Further qualitative research should include more people from underserved groups.

Tuberculosis screening in the European migrant population: a scoping review of current practices

Responding to a surge in new tuberculosis (TB) cases among migrants from high-incidence countries, low-incidence European nations have heeded World Health Organization recommendations by implementing TB screening in this population. This review aims to synthesise evidence on current screening strategies for active TB and latent tuberculosis infection (LTBI) in European high-income countries, and their main barriers and interventions. PubMed, Web of Science and Scopus were searched from March to April 2023, including articles in English, published in the last decade, pertaining to screening strategies for active TB or LTBI in Europe focused on migrants, excluding those exclusively composed of refugees, asylum seekers or other migrant populations. 32 studies fit the criteria. Screening in migrants varies between countries regarding timing, population, screening location and diagnosis. Furthermore, some barriers prevent migrants from benefiting from screening, namely physical, cultural and professional barriers. Additional research is needed to determine the patterns through which regular migrants adhere to current screening strategies in European countries.

Active Case Finding for Tuberculosis in Migrants: a Systematic Review

Background

Active case finding (ACF) is an alternative strategy to accelerate the identification of TB cases among the migrant population.

Objective

This study aimed to synthesize the evidence for the effectiveness of ACF TB in migrants.

Methods

This study uses the PRISMA model as a method of searching for journal articles in the databases of Google Scholar, ProQuest, EBSCO, ScienceDirect, Elsevier, and PubMed, as well as other sources such as textbooks and reports from 2017 to 2021 with the keywords "tuberculosis" AND "active case finding" AND "migrant". The search revealed 371 articles, of which 26 met the criteria for further discussion.

Results

Most studies show that the TB incidence among migrants is higher than in the local population. Factors leading to increased cases include lack of knowledge about the symptoms, high mobilization, social isolation, economic problems, and medication adherence that impact an advanced stage. Furthermore, it is also influenced by the low quality of health services, including accessibility, health facilities, health workers, and information. Therefore, Active Case Finding (ACF) is more effective in identifying cases of TB in the risk groups. This was conducted on migrants with increased notifications followed up with treatment.

Conclusion

ACF is effective approach in screening and diagnosing TB in the migrant group.

How can we improve latent tuberculosis infection management using behaviour change wheel: a systematic review

BACKGROUND

To ensure the effective delivery of latent tuberculosis infection (LTBI) care, it is vital to overcome potential challenges in LTBI management. This systematic review aims to identify the barriers and interventions to improve LTBI management using the Capability, Opportunity, and Motivation-Behaviour (COM-B) model and Behaviour Change Wheel (BCW).

METHODS

A systematic literature search was performed on five electronic databases from database inception to 3 November 2021. A two-step technique was used in the data synthesis process: (i) the barriers of LTBI management were identified using the COM-B model, followed by (ii) mapping of intervention functions from BCW to address the identified barriers.

RESULTS

Forty-seven eligible articles were included in this review. The findings highlighted the need for a multifaceted approach in tackling the barriers in LTBI management across the public, provider and system levels. The barriers were summarized into suboptimal knowledge and misperception of LTBI, as well as stigma and psychosocial burden, which could be overcome with a combination of intervention functions, targeting education, environment restructuring, persuasion, modelling, training, incentivization and enablement.

CONCLUSIONS

The remedial strategies using BCW to facilitate policy reforms in LTBI management could serve as a value-added initiative in the global tuberculosis control and prevention program.

A Study on the Health-Related Issues and Behavior of Vietnamese Migrants Living in Japan: Developing Risk Communication in the Tuberculosis Response

Ensuring a healthy lifestyle for the increasing number of Vietnamese migrants living in Japan is a key public health issue, including infectious disease responses such as tuberculosis (TB). To develop risk communication in relation to the TB response, this study aimed to explore the health issues and health-related behaviors of Vietnamese migrants living in Japan using a mixed method. A survey was conducted on Vietnam-born migrants, aged 18 years and over, in Tokyo. The survey consisted of questions on the following components: (1) demographics; (2) health-related issues and behavior; and (3) health-seeking behavior, information, and communication. A total 165 participants participated in the survey. The majority of the participants were young adults. 13% of the participants responded that they were concerned about their health. Moreover, 22% and 7% of the participants reported weight loss and respiratory symptoms, respectively. 44% of the participants answered they had no one to consult about their health in Japan when they needed it, and 58% answered they had no awareness of any Vietnamese-language health consultation services. Logistic regression analysis revealed that people who contact family members living in Vietnam or overseas using social networking services (SNSs) when they needed to consult someone about their health (adjusted odds ratio (AOR) = 6.09, 95% confidence interval (CI) 1.52-24.43) were more likely to present with one or more of the typical TB symptoms, compared to those who did not consult someone in this manner. Current smokers (OR = 3.08, 95% CI 1.15-8.23) were more likely to have health problems compared to non-smokers. The key informant interviews revealed that individual factors, the health system, and socio-environmental factors may hinder Vietnamese migrants' health-seeking and health-information-seeking behaviors in Japan. TB risk communication approaches for migrants need to be developed considering their health-related behaviors while addressing their health needs.

Barriers adult refugees face to community health and patient engagement: a systematic review

Meeting the health needs of refugee populations and increasing access to healthcare remains a challenge for healthcare systems globally. As such, community health and patient engagement are increasingly recommended strategies to address health-related issues among refugees. This systematic review aims to identify the reported barriers that adult refugees encounter with community health and patient engagement. Data sources included MEDLINE, Embase, APA PsycINFO, CINAHL, and Core Collection (Web of Science), yielding 1156 records. After removing duplicates and two levels of screening, 18 studies were selected for qualitative analysis. The barriers were conceptualised as cultural norms, pre-departure history, education, language proficiency, stigma, racism, social support, and multi-factorial barriers. These barriers can be addressed to improve rapport with refugees and the quality of community health and patient engagement initiatives.

Improving primary health care quality for refugees and asylum seekers: A systematic review of interventional approaches

Background

It has been widely acknowledged that refugees are at risk of poorer health outcomes, spanning mental health and general well‐being. A common point of access to health care for the migrant population is via the primary health care network in the country of resettlement. This review aims to synthesize the evidence of primary health care interventions to improve the quality of health care provided to refugees and asylum seekers.

Methods

A systematic review was undertaken, and 55 articles were included in the final review. The Preferred Reporting Items for Systematic Reviews was used to guide the reporting of the review, and articles were managed using a reference‐management software (Covidence). The findings were analysed using a narrative empirical synthesis. A quality assessment was conducted for all the studies included.

Results

The interventions within the broad primary care setting could be organized into four categories, that is, those that focused on developing the skills of individual refugees/asylum seekers and their families; skills of primary health care workers; system and/or service integration models and structures; and lastly, interventions enhancing communication services. Promoting effective health care delivery for refugees, asylum seekers and their families is a complex challenge faced by primary care professionals, the patients themselves and the communication between them.

Conclusion

This review highlights the innovative interventions in primary care promoting refugee health. Primary care interventions mostly focused on upskilling doctors, with a paucity of research exploring the involvement of other health care members. Further research can explore the involvement of interprofessional team members in providing effective refugee/migrant health.

Patient or Public Contribution

Patient and public involvement was explored in terms of interventions designed to improve health care delivery for the humanitarian migrant population, that is, specifically refugees and asylum seekers.

Trend and treatment outcomes of latent tuberculosis infection among migrant persons in Japan: retrospective analysis of Japan tuberculosis surveillance data

BACKGROUND

Screening for latent tuberculosis infection (LTBI) among migrant population has become a critical issue for many low tuberculosis (TB) burden countries. Evidence regarding effectiveness of LTBI programs are limited, however, partly because of paucity of national data on treatment outcomes for LTBI. In Japan, notification of LTBI is mandatory, and its treatment outcome is reported as part of Japan's national TB surveillance system. We thus conducted a detailed analysis of LTBI among foreign-born persons, to update the epidemiological trend of newly notified LTBI between 2007 and 2018, and to examine the treatment regimen and outcome of those notified in 2016 and 2017, focusing specifically on the potential risk factors for lost to follow-up.

METHODS

We extracted and analyzed the data of newly notified LTBI patients from the Japan Tuberculosis Surveillance System to examine the overall trend of notification and by age groups and modes of detection between 2007 and 2018, and the cohort data for treatment regimen and outcomes of foreign-born persons notified with LTBI in 2016 and 2017. Trends and proportions were summarized descriptively, and logistic regression analysis was conducted to identify potential risk factors for lost to follow-up. Comparisons were made with the Japan-born patients where appropriate, using chi-squared tests.

RESULTS

Both the number and proportion of LTBI among foreign-born persons have been constantly increasing, reaching 963 cases in 2018. Cohort analysis of the surveillance data indicated that the proportion of those on shorter regimen was higher among the foreign- than Japan-born patients (5.5% vs. 1.8%, p < 0.001). The proportion of those who have been lost to follow-up and transferred outside of Japan combined was higher among the foreign- than Japan-born patients (12.0% vs, 8.2%, p < 0.001). Risk factors for lost to follow-up were being employed on a temporal basis, and job status unknown (adjusted odds ratios 3.11 and 4.09, 95% confidence intervals 1.34-7.26 and 1.60-10.48, respectively).

CONCLUSIONS

Migrant population face greater risk of interrupting LTBI treatment, and interventions to improve adherence are a critical component of programmatic management of LTBI. Further studies are needed to explore the cultural and socioeconomic situation in which foreign-born persons undergo LTBI treatment in Japan.

Towards elimination of childhood and adolescent tuberculosis in the Netherlands: an epidemiological time-series analysis of national surveillance data

BACKGROUND

Tuberculosis (TB) in children and adolescents is a sentinel event for ongoing transmission. In the Netherlands, epidemiological characteristics of childhood and adolescent TB have not been fully evaluated. Therefore, we aimed to assess TB epidemiology within this population to provide guidance for TB elimination.

METHODS

A retrospective time-series analysis using national surveillance data from 1993-2018 was performed in children (aged <15 years) and adolescents (aged 15-19 years) with TB. Poisson regression models offset with log-population size were used to estimate notification rates and rate ratios. Trends in notification rates were estimated using average annual percentage changes (AAPC) based on the segmented linear regression analysis.

RESULTS

Among 3899 children and adolescents with TB notified during 1993-2018, 2418 (62%) were foreign-born (725 (41.3%) out of 1755 children and 1693 (78.9%) out of 2144 adolescents). The overall notification rate in children was 2.3 per 100 000 person-years, declining steadily during the study period (AAPC -10.9%, 95% CI -12.6--9.1). In adolescents, the overall notification rate was 8.4 per 100 000 person-years, strongly increasing during 1993-2001 and 2012-2018. Compared to Dutch-born children and adolescents, substantially higher notification rates were observed among African-born children and adolescents (116.8 and 316.6 per 100 000 person-years, respectively). Additionally, an increasing trend was observed in African-born adolescents (AAPC 18.5%, 95% CI 11.9-25.5). Among the foreign-born population, those from countries in the horn of Africa contributed most to the TB caseload.

CONCLUSION

TB notification rate among children was low and constantly declining across different demographic groups. However, heterogeneities were shown in adolescents, with an increasing trend in the foreign-born, particularly those from Africa.

Knowledge, attitudes, beliefs, and stigma related to latent tuberculosis infection: a qualitative study among Eritreans in the Netherlands

Background

Tailored and culturally appropriate latent tuberculosis (TB) infection screening and treatment programs, including interventions against TB stigma, are needed to reduce TB incidence in low TB incidence countries. However, we lack insights in stigma related to latent TB infection (LTBI) among target groups, such as asylum seekers and refugees. We therefore studied knowledge, attitudes, beliefs, and stigma associated with LTBI among Eritrean asylum seekers and refugees in the Netherlands.

Methods

We used convenience sampling to interview adult Eritrean asylum seekers and refugees: 26 semi-structured group interviews following TB and LTBI related health education and LTBI screening, and 31 semi-structured individual interviews with Eritreans during or after completion of LTBI treatment (November 2016–May 2018). We used a thematic analysis to identify, analyse and report patterns in the data.

Results

Despite TB/LTBI education, misconceptions embedded in cultural beliefs about TB transmission and prevention persisted. Fear of getting infected with TB was the cause of reported enacted (isolation and gossip) and anticipated (concealment of treatment and self-isolation) stigma by participants on LTBI treatment.

Conclusion

The inability to differentiate LTBI from TB disease and consequent fear of getting infected by persons with LTBI led to enacted and anticipated stigma comparable to stigma related to TB disease among Eritreans. Additional to continuous culturally sensitive education activities, TB prevention programs should implement evidence-based interventions reducing stigma at all phases in the LTBI screening and treatment cascade.
