Infectious disease screening in asylum seekers: range, coverage and economic evaluation in Germany, 2015

Prevention, testing, and treatment interventions for hepatitis B and C in refugee populations: results of a scoping review

BACKGROUND AND AIMS

Refugees are at higher risk for hepatitis B (HBV) and hepatitis C (HCV), but often face unique healthcare barriers to vaccination, testing, and treatment. This scoping review aimed to identify and characterize HBV and HCV prevention and care services serving refugee populations globally.

METHODS

A literature search was conducted on Embase, Cochrane, and PubMed databases. Research studies published in English between January 2010 to July 2022 describing an HBV or HCV prevention, testing, or treatment intervention for refugees were included.

RESULTS

There were a total of 69 articles reporting viral hepatitis prevalence, implementation of services, or economic modelling. Of the 38 implementation studies, 14 were stand-alone HBV and/or HCV interventions, while 24 studies included HBV and/or HCV in an intervention targeting multiple infectious diseases and/or parasitic infections. Interventions commonly included a testing (n = 30) or referral (n = 24) component. Frequently reported features to promote program accessibility included bilingual services (n = 25), community partnerships (n = 21), and multidisciplinary staff members (n = 18), such as cultural and/or linguistic mediators, community health workers, community health leaders, lay health workers, local health staff, members of the refugee community, and social workers. The most commonly reported challenge was the transience of refugees (n = 5). Twenty studies noted funding sources, of which twelve reported governmental funding (not including national health insurance) and eight reported that refugees received national health insurance.

CONCLUSIONS

This is the first scoping review to characterize the types of hepatitis prevention, screening, and treatment interventions serving refugee populations globally. Published experiences of HBV and HCV services for refugee populations remain limited. Additional efforts are needed to disseminate models of hepatitis interventions for refugees to ensure access to care for this key population. To achieve hepatitis elimination globally, best practices must be identified and shared to expand access to hepatitis services for refugee populations.

Comparable worth of life for all? Conducting and disseminating health economic evaluations for refugees in Germany

Comparative health economic evaluation is based on premise of being able to compare the worth of a year of life lived in full quality across different patients, population groups, settings and interventions. Given the rising numbers of forcibly displaced people, the nexus of economics, migration and health has emerged as a central theme in recent conceptual and empirical approaches. However, some of the assumptions made in conventional economic approaches do not hold true in the decision-making context of migration and the health of forcibly displaced populations. Using the experience of conducting and disseminating economic analyses to support decision-making on health screening policies for refugees in Germany, we show that in particular the assumptions of individual utility with no positive externalities, equity-blind utilitarian ethical stances and stable budgets are challenged. The further development of methods to address these challenges are required to support decision-makers in this contentious and politically fraught context and continue to make choices and decisions transparent.

Reducing burden from respiratory infections in refugees and immigrants: a systematic review of interventions in OECD, EU, EEA and EU-applicant countries

BACKGROUND

Respiratory diseases are a major reason for refugees and other immigrants seeking health care in countries of arrival. The burden of respiratory diseases in refugees is exacerbated by sometimes poor living conditions characterised by crowding in mass accommodations and basic living portals. The lack of synthesised evidence and guideline-relevant information to reduce morbidity and mortality from respiratory infections endangers this population.

METHODS

A systematic review of all controlled and observational studies assessing interventions targeting the treatment, diagnosis and management of respiratory infections in refugees and immigrants in OECD, EU, EEA and EU-applicant countries published between 2000 and 2019 in MEDLINE, CINAHL, PSYNDEX and the Web of Science.

RESULTS

Nine of 5779 identified unique records met our eligibility criteria. Seven studies reported an increase in vaccine coverage from 2 to 52% after educational multilingual interventions for respiratory-related childhood diseases (4 studies) and for influenza (5 studies). There was limited evidence in one study that hand sanitiser reduced rates of upper respiratory infections and when provided together with face masks also the rates of influenza-like-illness in a hard to reach migrant neighbourhood. In outbreak situations of vaccine-preventable diseases, secondary cases and outbreak hazards were reduced by general vaccination strategies early after arrival but not by serological testing after exposure (1 study). We identified evidence gaps regarding interventions assessing housing standards, reducing burden of bacterial pneumonia and implementation of operational standards in refugee care and reception centres.

CONCLUSIONS

Multilingual health literacy interventions should be considered to increase uptake of vaccinations in refugees and immigrants. Immediate vaccinations upon arrival at refugee housings may reduce secondary infections and outbreaks. Well-designed controlled studies on housing and operational standards in refugee and immigrant populations early after arrival as well as adequate ways to gain informed consent for early vaccinations in mass housings is required to inform guidelines.

Is there a need of health assessments for resettling refugees? A cross-sectional study of 1431 refugees who arrived in Denmark between 2014 and 2018

BACKGROUND

Refugees have increased health risks due to factors related to their country of origin, the migration itself and the receiving country. Based on systematic general health assessments of newly arrived refugees, we aimed to study the characteristics with regard to background, migration and health needs.

METHODS

All refugees (children/adolescents and adults) arriving in Aarhus, Denmark from 1 January 2014 to 1 November 2018 were offered a general health assessment by a doctor including: medical history, a physical examination and blood samples.

RESULTS

A cohort of 1431 (of 1618 invited, (88.4%) participants accepted the health assessment. The most commonly found health conditions in children were vitamin D deficiency (28.3%), elevated serum-IgE (34%) and lack of immunity against vaccine-preventable diseases (measles 20.1%, polio 3.9%). In adults, vitamin D deficiency (34.6%), IgE elevation (30%), latent tuberculosis (20.3%) and symptoms of PTSD (15.9%) were most prevalent. We found participants from Southern Asia (Iran, Afghanistan and Pakistan) to be overrepresented with regard to vitamin D deficiency, vitamin B12 deficiency and symptoms of PTSD. Furthermore, we found that origin in Africa was associated with latent tuberculosis. In total, 63.8% of examined refugees had one or more health problems requiring further testing, treatment or follow-up.

CONCLUSIONS

A comprehensive health assessment among recently arrived refugees showed multiple health issues to address, and demonstrates the need of systematic health assessments for resettling refugees.

Socioeconomic deprivation is inversely associated with measles incidence: a longitudinal small-area analysis, Germany, 2001 to 2017

BackgroundAlthough measles is endemic throughout the World Health Organization European Region, few studies have analysed socioeconomic inequalities and spatiotemporal variations in the disease's incidence.AimTo study the association between socioeconomic deprivation and measles incidence in Germany, while considering relevant demographic, spatial and temporal factors.MethodsWe conducted a longitudinal small-area analysis using nationally representative linked data in 401 districts (2001-2017). We used spatiotemporal Bayesian regression models to assess the potential effect of area deprivation on measles incidence, adjusted for demographic and geographical factors, as well as spatial and temporal effects. We estimated risk ratios (RR) for deprivation quintiles (Q1-Q5), and district-specific adjusted relative risks (ARR) to assess the area-level risk profile of measles in Germany.ResultsThe risk of measles incidence in areas with lowest deprivation quintile (Q1) was 1.58 times higher (95% credible interval (CrI): 1.32-2.00) than in those with highest deprivation (Q5). Areas with medium-low (Q2), medium (Q3) and medium-high deprivation (Q4) had higher adjusted risks of measles relative to areas with highest deprivation (Q5) (RR: 1.23, 95%CrI: 0.99-1.51; 1.05, 95%CrI: 0.87-1.26 and 1.23, 95%CrI: 1.05-1.43, respectively). We identified 54 districts at medium-high risk for measles (ARR > 2) in Germany, of which 22 were at high risk (ARR > 3).ConclusionSocioeconomic deprivation in Germany, one of Europe's most populated countries, is inversely associated with measles incidence. This association persists after demographic and spatiotemporal factors are considered. The social, spatial and temporal patterns of elevated risk require targeted public health action and policy to address the complexity underlying measles epidemiology.

Estimating and Explaining the Prevalence of Tuberculosis for Asylum Seekers Upon Their Arrival in Germany

Up until recently incidences of tuberculosis (TB) had been declining for many years in Germany. The rise in TB cases coincided with a large increase in the number of people applying for asylum. We combine data from various sources to estimate the at-entry prevalence of TB for asylum seekers from 18 countries of origin and rely on survey data to explain the varying risk of suffering from TB. Our results reveal that asylum seekers from Eastern Africa show a much higher risk of suffering from TB than asylum seekers from Afghanistan, Syria, or Iraq. The survey data suggests that asylum seekers from Africa were by far more underprivileged in their respective countries of origin and experienced a higher risk of contracting TB on their way to Germany. Information about the socio-economic situation and the circumstances of the journey to Germany may help to improve TB surveillance.

Referrals to secondary care in an outpatient primary care walk-in clinic for refugees in Germany: results from a secondary data analysis based on electronic medical records

OBJECTIVES

The aims of our study were to describe the disease spectrum of refugees, to analyse to what extent their healthcare needs could be met in an outpatient primary care walk-in clinic and which cases required additional services from secondary care (ie, outpatient specialists or hospitals).

DESIGN

Retrospective longitudinal observational study.

SETTING

The study was based on routine data from a walk-in clinic in the largest central first reception centre in Hamburg, Germany between 4 November 2015 and 21 July 2016.

PARTICIPANTS

1467 asylum seekers with 4006 episodes of care (ie, distinctive health problems) resulting in 5545 consultations. The patients were 60% men and had a mean age of 23.2 years. About 90% of the patients were from Central Asia or from the Middle East and North Africa.

PRIMARY AND SECONDARY OUTCOME MEASURES

The endpoint of our analyses was referral to secondary care. Time to event was defined as days under treatment until the first referral. Predictor variables were the patients' diagnoses grouped in 46 categories. The data set was analysed by Cox regression allowing for multiple failure times per patient. This analysis was adjusted for age, sex and country of origin.

RESULTS

Referrals to secondary care occurred in 15.5% of the episodes. The diagnosis groups with the highest referral rates were 'eye' (HR 4.9; 95% CI 3.12 to 7.8; p≤0.001), 'teeth/gum symptom/complaint or disease' (3.51; 2.52 to 4.9; p≤0.001) and 'urological system/female or male genital' (2.50; 1.66 to 3.77; p≤0.001). Age, sex and country of origin had no significant effect on time until referral.

CONCLUSIONS

In most cases, the walk-in clinic physicians could provide first-line medical care for the health problems of patients not integrated in the German healthcare system. Additional resources were needed particularly not only for visual impairment and dental problems but also for psychological disorders, antenatal care and certain infections and injuries.

Comprehensive infectious disease screening in a cohort of unaccompanied refugee minors in Germany from 2016 to 2017: A cross-sectional study

BACKGROUND

Information regarding the prevalence of infectious diseases (IDs) in child and adolescent refugees in Europe is scarce. Here, we evaluate a standardized ID screening protocol in a cohort of unaccompanied refugee minors (URMs) in a municipal region of southwest Germany.

METHODS AND FINDINGS

From January 2016 to December 2017, we employed a structured questionnaire to screen a cohort of 890 URMs. Collecting sociodemographic information and medical history, we also performed a standardized diagnostics panel, including complete blood count, urine status, microbial stool testing, tuberculosis (TB) screening, and serologies for hepatitis B virus (HBV) and human immunodeficiency virus (HIV). The mean age was 16.2 years; 94.0% were male, and 93.6% originated from an African country. The most common health complaints were dental problems (66.0%). The single most frequent ID was scabies (14.2%). Of the 776 URMs originating from high-prevalence countries, 7.7% and 0.4% tested positive for HBV and HIV, respectively. Nineteen pathogens were detected in a total of 119 stool samples (16.0% positivity), with intestinal schistosomiasis being the most frequent pathogen (6.7%). Blood eosinophilia proved to be a nonspecific criterion for the detection of parasitic infections. Active pulmonary TB was identified in 1.7% of URMs screened. Of note, clinical warning symptoms (fever, cough >2 weeks, and weight loss) were insensitive parameters for the identification of patients with active TB. Study limitations include the possibility of an incomplete eosinophilia workup (as no parasite serologies or malaria diagnostics were performed), as well as the inherent selection bias in our cohort because refugee populations differ across Europe.

CONCLUSIONS

Our study found that standardized ID screening in a URM cohort was practicable and helped collection of relevant patient data in a thorough and time-effective manner. However, screening practices need to be ameliorated, especially in relation to testing for parasitic infections. Most importantly, we found that only a minority of infections were able to be detected clinically. This underscores the importance of active surveillance of IDs among refugees.

Implications of a change in case definition and screening of asylum seekers for hepatitis B surveillance in Germany in 2015 and 2016

Since 2015, the number of hepatitis B virus (HBV) cases increased substantially in Germany. In 2015, a more sensitive HBV case definition was introduced. This coincided with an asylum seeker influx with differing screening strategies. Information on the asylum seeker status has been collected since 09/2015. We investigated this increase to interpret HBV notification data in Germany. We compared HBV surveillance data from 2010–2013 (baseline) with 2015–2016, excluding 2014 due to beginning of asylum seeker influx. We estimated the excess above the mean case number (baseline) using Poisson regression and compared asylum seeker cases and the excess of cases with the unknown asylum seeker status. HBV cases increased from 1855 (mean baseline) to 3873 (2015) and 3466 (2016) with 1903 asylum seeker cases and 1099 excess-cases with the unknown asylum seeker status in 2015–2016. Cases only fulfilling the changed case definition increased from 60% (1119) in baseline to 81% (P < 0.01) in 2015–2016; 69% of asylum seeker cases and 61% of excess-cases were males <40 years compared to 27% (baseline) (P < 0.01). Changed case definition increased the number of cases in official statistics substantially. Demographic and geographical distributions suggest that screening of asylum seekers increased the case numbers even to a higher extent than surveillance data indicates.

„Da muss sich jemand anders kümmern“ – Die medizinische Versorgung von Asylsuchenden als Herausforderung für eine bio-psycho-soziale Medizin

Ziel der Studie Die Medizin wird verschiedentlich dafür kritisiert, die biologischen Facetten von Gesundheit und Krankheit gegenüber gesellschaftlichen Einflüssen zu privilegieren. Gegen diesen Vorwurf hat sich in den letzten Jahrzehnten ein medizintheoretischer Ansatz etabliert, der ein bio-psycho-soziales Krankheitskonzept vertritt. Dieser Artikel nutzt ethnografische Perspektiven auf die medizinische Versorgung von Asylsuchenden, um zu untersuchen, inwiefern die Prinzipien der bio-psycho-sozialen Medizin in Bezug auf die wissenschaftlich fundierte Berücksichtigung gesellschaftlicher Einflüsse auf die Gesundheit und Krankheit dieser Patientengruppe verwirklicht werden.

Methoden Dabei findet ein ethnografisches Methodenrepertoire mit narrativen Interviews, Leitfadeninterviews und teilnehmender Beobachtung Anwendung.

Ergebnisse Anhand des Umgangs mit den rechtlichen Rahmenbedingungen der medizinischen Versorgung von Asylsuchenden und mit Sprachinkongruenz wird gezeigt, dass es Ärzt/-innen regelmäßig nicht gelingt, die gesundheitsbezogene Lebenswelt dieser Patientengruppe adäquat und wissenschaftlichen Standards entsprechend in Diagnostik und Therapie zu berücksichtigen. Stattdessen rekurrieren sie im klinischen Alltag häufig auf improvisierte Lösungsansätze oder verschieben die Verantwortung auf andere, oft unbenannte Akteure.

Schlussfolgerung Sozialwissenschaftliche Ansätze, v. a. aus der Medizinanthropologie, könnten diese zu Versorgungsdefiziten führenden Schwierigkeiten beheben und sollten daher vermehrt in die ärztliche Aus- und Weiterbildung integriert werden. Dadurch könnten zudem theoretische und methodische Lücken geschlossen werden, die möglicherweise auch in der Versorgung anderer Patientengruppen bedeutsam sind.

The impact of patient-held health records on continuity of care among asylum seekers in reception centres: a cluster-randomised stepped wedge trial in Germany

Introduction

The aim of this study was to assess the effectiveness of a patient-held health record (PHR) for asylum seekers on the availability of health-related information.

Methods

An explorative, cluster-randomised stepped-wedge trial with reception centres as unit of randomisation was conducted. All reception centres (n=6) in two large administrative areas in South Germany with on-site health services were included. All physicians working at these centres were invited to participate in the study. The intervention was the implementation of a PHR. The primary outcome was the prevalence of written health-related information. Secondary outcomes were the physicians’ dissatisfaction with the available written information and the prevalence of missing health-related information. All outcomes were measured at the level of patient–physician contacts by means of a standardised questionnaire, and analysed in logistic multi-level regression models.

Results

We obtained data on 2308 patient–physician contacts. The presence of the PHR increased the availability of health-related information (adjusted OR (aOR), 20.3, 95% CI: 12.74 to 32.33), and tended to reduce missing essential information (aOR 0.71, 95% CI: 0.39 to 1.26) and physicians’ dissatisfaction with available information (aOR 0.5, 95% CI: 0.24 to 1.04). The availability of health-related information in the post-intervention period was higher (aOR 4.22, 95% CI: 2.64 to 6.73), missing information (aOR 0.89, 95% CI: 0.42 to 1.88) and dissatisfaction (aOR 0.43, 95% CI: 0.16 to 1.14) tended to be lower compared with the pre-intervention period.

Conclusions

Healthcare planners should consider introducing PHRs in reception centres or comparable facilities. Future research should focus on the impact of PHRs on clinical outcomes and on intersectoral care.

Using country of origin to inform targeted tuberculosis screening in asylum seekers: a modelling study of screening data in a German federal state, 2002-2015

BACKGROUND

Screening programmes for tuberculosis (TB) among immigrants rarely consider the heterogeneity of risk related to migrants' country of origin. We assess the performance of a large screening programme in asylum seekers by analysing (i) the difference in yield and numbers needed to screen (NNS) by country and WHO-reported TB burden, (ii) the possible impact of screening thresholds on sensitivity, and (iii) the value of WHO-estimated TB burden to improve the prediction accuracy of screening yield.

METHODS

We combined individual data of 119,037 asylum seekers screened for TB in Germany (2002-2015) with TB estimates of the World Health Organization (WHO) (1990-2014) for their 81 countries of origin. Adjusted rate ratios (aRR) and 95% credible intervals (CrI) of the observed yield of screening were calculated in Bayesian Poisson regression models by categories of WHO-estimated TB incidence. We assessed changes in sensitivity depending on screening thresholds, used WHO TB estimates as prior information to predict TB in asylum seekers, and modelled country-specific probabilities of numbers needed to screen (NNS) conditional on different screening thresholds.

RESULTS

The overall yield was 82 per 100,000 and the annual yield ranged from 44.1 to 279.7 per 100,000. Country-specific yields ranged from 10 (95%- CrI: 1-47) to 683 (95%-CrI: 306-1336) per 100,000 in Iraqi and Somali asylum seekers, respectively. The observed yield was higher in asylum seekers from countries with a WHO-estimated TB incidence > 50 relative to those from countries ≤50 per 100,000 (aRR: 4.17, 95%-CrI: 2.86-6.59). Introducing a threshold in the range of a WHO-estimated TB incidence of 50 and 100 per 100,000 resulted in the lowest "loss" in sensitivity. WHO's TB prevalence estimates improved prediction accuracy for eight of the 11 countries, and allowed modelling country-specific probabilities of NNS.

CONCLUSIONS

WHO's TB data can inform the estimation of screening yield and thus be used to improve screening efficiency in asylum seekers. This may help to develop more targeted screening strategies by reducing uncertainty in estimates of expected country-specific yield, and identify thresholds with lowest loss in sensitivity. Further modelling studies are needed which combine clinical, diagnostic and country-specific parameters.

'Valuable but incomplete!' A qualitative study about migrants' perspective on health examinations in Stockholm

Background

A voluntary health examination is offered to asylum seekers in Sweden with the purpose of detecting infectious diseases and identifying other health needs. This study aimed to explore the organization, content and perceived value of the health examination from the perspective of asylum seekers.

Methods

Semi-structured interviews were conducted with 18 migrants recruited from different settings in Stockholm. Data were transcribed verbatim and analysed using thematic analysis in relation to the availability, accessibility, acceptability and quality framework.

Results

Participants reported positive aspects of the health examination while raising important concerns, categorized into the following themes: availability-despite being available, the service was considered to be delayed with perceived implication for infection control; accessibility-migrants experienced no physical or economic barrier to access the health examination, especially when it was performed through a mobile clinic, however, they had limited access to information; acceptability and quality-migrants trusted the health staff, however, the examination lacked important aspects related to mental health and dental care needs, among other health needs.

Conclusion

Health examinations are valued by participants but failed to identify and address many perceived health needs. Mobile clinics seem a practical strategy to improve accessibility.

Public health response to large influx of asylum seekers: implementation and timing of infectious disease screening

BACKGROUND

Infectious disease screening of migrants at increased risk is a feature of national infection prevention and control measures. Asylum seekers in Finland are offered screening of tuberculosis (TB), hepatitis B, human immunodeficiency virus infection (HIV) and syphilis based on individual risk assessment. We aimed to evaluate the public health response to a large influx of asylum seekers to Finland in 2015-2016 with respect to national guidelines on initial health services and infectious disease screening.

METHODS

We used immigration and healthcare procurement data for all 38,134 asylum seekers to Finland during 2015-2016 to assess the implementation, timing and yields of infectious disease screening.

RESULTS

The coverage of pulmonary TB screening was 71.6% [95% CI 71.1-72.0%] and that of hepatitis B, HIV or syphilis 60.6% [60.1-61.1%] among those eligible for screening. The estimated average delay from arrival to pulmonary TB screening was 74 days for adults and 43 days for children. Delay to hepatitis B, HIV and syphilis screening was 91 days for adults and 47 days for children. The seroprevalence of hepatitis B surface antigen positivity was 1.4% [95% CI 1.3-1.6%], HIV 0.3% [95% CI 0.1-0.4%] and Treponema pallidum specific antibodies 1.0% [95% CI 0.8-1.1%]. Data did not allow assessment of yields of pulmonary TB screening.

CONCLUSIONS

Up to one third  of asylum seekers were not reached by screening and screenings were delayed from target timeframes. Children, as a vulnerable population, were screened earlier than adults. To ensure higher screening coverage, infectious disease risks should be reassessed and screening completed at contacts to healthcare during the post-asylum phase of integration. The large influx of asylum seekers to Finland in 2015-2016 tested the country's public health preparedness. After action reviews of the public health response to the large migrant influx such as screening implementation can be used for evidence-based improvement of public health preparedness and guidelines for initial health services and infectious disease screening.

Early evaluation of experiences of health care providers in reception centers with a patient-held personal health record for asylum seekers: a multi-sited qualitative study in a German federal state

BACKGROUND

The provision of high-quality medical care to asylum seekers represents a key challenge in many countries of the European Union. Especially continuity of care has been difficult to achieve as the migrant trajectory moves asylum seekers across and within European countries. Patient-held personal health records (PHR) have been proposed to facilitate the transfer of medical history between health sectors and providers, but so far there is no data to support its use in the migrant setting. The present paper addresses this knowledge gap by exploring the experiences and practices of healthcare providers in reception centers for asylum seekers using a patient-held PHR as well as the perceived associated benefits and shortcomings.

METHODS

Early evaluation by means of a multi-sited qualitative study in six asylum seeker reception centers in five cities in the German state of Baden-Wuerttemberg, conducted between November 2016 and January 2017. The PHR evaluated in this study was implemented in five of these reception centers between February and October 2016; the remaining one only receiving patients with the PHR through transfer from the other facilities. 17 interviews were conducted with physicians and nurses working at these reception centers exploring their experiences, routines, and perspectives regarding the patient-held PHR. The interviews were recorded, transcribed and analyzed following the approach of thematic analysis.

RESULTS

Healthcare providers recognise the potential of a patient-held PHR to improve access to medical history. They use the PHR to document their medical consultations and to collect other medical reports. However, physician adherence to the patient-held PHR was described as unsatisfactory, in particular among external doctors, thus limiting its immediate benefit. Reasons given for this low adherence included lack of information before implementation, demanding working conditions with little support, low perceived benefits depending on the degree of fragmentation of settings, parallel existence of other documentation platforms and strained patient relationships.

CONCLUSION

A patient-held PHR could improve the availability of health-related information in reception centers if a context-sensitive implementation process achieves high adherence to the PHR among physicians as well as high patient compliance and includes guidelines regarding its adequate integration into local routines.

How effective are approaches to migrant screening for infectious diseases in Europe? A systematic review

Rates of migration to Europe, and within Europe, have increased in recent years, with considerable implications for health systems. Migrants in Europe face a disproportionate burden of tuberculosis, HIV, and hepatitis B and C, yet experience a large number of barriers to accessing statutory health care on arrival. A better understanding of how to deliver effective and cost-effective screening, vaccination, and health services to this group is now crucial. We did a systematic review to document and assess the effectiveness and cost-effectiveness of approaches used for infectious diseases screening, and to explore facilitators and barriers experienced by migrants to accessing screening programmes. Following PRISMA guidelines, we searched Embase, PubMed, PsychINFO, the Cochrane Library, and Web of Science (1989 to July 1, 2015, updated on Jan 1, 2018), with no language restrictions, and systematically approached experts across the European Union (EU) for grey literature. Inclusion criteria were primary research studies assessing screening interventions for any infectious disease in the migrant (foreign-born) population residing in EU or European Economic Area (EEA) countries. Primary outcomes were the following effectiveness indicators: uptake of screening, coverage, infections detected, and treatment outcomes. Of 4112 unique records, 47 studies met our inclusion criteria, from ten European countries (Belgium, Denmark, France, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland, and the UK) encompassing 248 402 migrants. We found that most European countries screening migrants focus on single diseases only-predominantly active or latent tuberculosis infection-and specifically target asylum seekers and refugees, with 22 studies reporting on other infections (including HIV and hepatitis B and C). An infection was detected in 3·74% (range 0·00-95·16) of migrants. Latent tuberculosis had the highest prevalence across all infections (median 15·02% [0·35-31·81]). Uptake of screening by migrants was high (median 79·50% [18·62-100·00]), particularly in primary health-care settings (uptake 96·77% [76·00-100·00]). However, in 24·62% (0·12-78·99) of migrants screening was not completed and a final diagnosis was not made. Pooled data highlight high treatment completion in migrants (83·79%, range 0·00-100·00), yet data were highly heterogeneous for this outcome, masking important disparities between studies and infections, with only 54·45% (35·71-72·27) of migrants with latent tuberculosis ultimately completing treatment after screening. Coverage of the migrant population in Europe is low (39·29% [14·53-92·50]). Data on cost-effectiveness were scarce, but suggest moderate to high cost-effectiveness of migrant screening programmes depending on migrant group and disease targeted. European countries have adopted a variety of approaches to screening migrants for infections; however, these are limited in scope to single diseases and a narrow subset of migrants, with low coverage. More emphasis must be placed on developing innovative and sustainable strategies to facilitate screening and treatment completion and improve health outcomes, encompassing multiple key infections with consideration given to a wider group of high-risk migrants. Policy makers and researchers involved with global migration need to ensure a longer-term view on improving health outcomes in migrant populations as they integrate into health systems in host countries.

Impact of HIV knowledge and stigma on the uptake of HIV testing - Results from a community-based participatory research survey among migrants from sub-Saharan Africa in Germany

Background

In 2015, 3,674 new HIV diagnoses were notified in Germany; 16% of those newly diagnosed cases originated from sub-Saharan Africa (sSA). One quarter of the newly diagnosed cases among migrants from sSA (MisSA) are notified as having acquired the HIV infection in Germany. In order to reach MisSA with HIV testing opportunities, we aimed to identify which determinants influence the uptake of HIV testing among MisSA in Germany.

Methods

To identify those determinants, we conducted a quantitative cross-sectional survey among MisSA in Germany. The survey was designed in a participatory process that included MisSA and other stakeholders in HIV-prevention. Peer researchers recruited participants to complete standardized questionnaires on HIV knowledge and testing. We conducted multivariable analyses (MVA) to identify determinants associated with ever having attended voluntary HIV testing; and another MVA to identify determinant associated with having had the last voluntary HIV test in Germany.

Results

Peer researchers recruited 2,782 participants eligible for inclusion in the MVA. Of these participants, 59.9% (1,667/2,782) previously had an HIV test. For each general statement about HIV that participants knew prior to participation in the study, the odds of having been tested increased by 19% (OR 1.19; 95%-CI: 1.11–1.27). Participants reporting that HIV is a topic that is discussed in their community had 92% higher odds of having been tested for HIV (OR 1.92; 95%-CI: 1.60–2.31). Migrants living in Germany for less than a year had the lowest odds of having had their last HIV test in Germany (OR 0.17; 95%-CI: 0.11–0.27). Additionally, MisSA 18 to 25 years (OR 0.55; 95%-CI: 0.42–0.73) and participants with varied sexual partners and inconsistent condom use (OR 0.75; 95%-CI: 0.44–0.97) had significantly lower odds of having had their last HIV test in Germany.

Discussion

Through participatory research, we were able to show that knowledge about HIV and discussing HIV in communities increased the odds of having attended HIV testing among MisSA. However, recent migrants and young sexually active people are among the least reached by testing offers in Germany. Community-based interventions may present opportunities to reach such migrants and improve knowledge and increase discussion about HIV.
