Mental Health and Traumatization of Newly Arrived Asylum Seeker Adults in Finland: A Population-Based Study.

Asylum seekers frequently experience potentially traumatic events (PTEs), but the type and frequency vary depending on the country of origin. The cumulative effect of multiple PTEs and other stressors expose asylum seekers to a significant risk of mental ill health. The aim of the study was to examine the prevalence of PTEs, depression and anxiety symptoms, risk for psychological trauma, psychotropic medication use and previous mental health diagnoses among adult asylum seekers in the Asylum Seekers Health and Wellbeing (TERTTU) Survey (n = 784 respondents, participation rate 78.6%). A substantial majority (88.7%, 95% CI 86.9-90.3) of asylum seekers reported one or more PTEs before arriving to Finland. PTEs during the asylum-seeking journey were reported at 12.0% (95% CI 10.7-13.4), however, when examined by region of origin, the proportion was 34.5% (95% CI 29.5-39.8) for asylum seekers from Africa (excluding North Africa). Significant symptoms of depression were reported by 41.7% (95% CI 39.6-43.9) of asylum seekers and symptoms of anxiety by 34.2% (95% CI 32.1-36.2). Half of the asylum seekers were assessed as having at least a medium-risk for psychological trauma. Prevalence rates were higher among females and asylum seekers from Africa. This study highlights the importance of using screening tools to identify asylum seekers with severe mental health problems that may need referral to further assessment and treatment. Asylum seekers from Africa (excluding North Africa) should be given additional attention in initial health screenings and examinations.

Tuberculosis screening of asylum seekers in Finland, 2015-2016.

BACKGROUND: In Finland, asylum seekers from countries with high tuberculosis (TB) incidence (> 50/100,000 population/year) and those coming from a refugee camp or conflict area are eligible for TB screening. The aim of this study was to characterise the TB cases diagnosed during screening and estimate the yield of TB screening at the reception centres among asylum seekers, who arrived in Finland during 2015-2016. METHODS: Voluntary screening conducted at reception centres included an interview and a chest X-ray. Data on TB screening and health status of asylum seekers was obtained from the reception centres' national health register (HRS). To identify confirmed TB cases, the National Infectious Disease Register (NIDR) data of foreign-born cases during 2015-2016 were linked with HRS data. TB screening yield was defined as the percentage of TB cases identified among screened asylum seekers, stratified by country of origin. RESULTS: During 2015-2016, a total of 38,134 asylum applications were received (57% were from Iraq, 16% from Afghanistan and 6% from Somalia) and 25,048 chest x-rays were performed. A total of 96 TB cases were reported to the NIDR among asylum seekers in 2015-2016; 94 (98%) of them had been screened. Screening identified 48 (50%) cases: 83% were male, 56% aged 18-34 years, 42% from Somalia, 27% from Afghanistan and 13% from Iraq. Furthermore, 92% had pulmonary TB, 61% were culture-confirmed and 44% asymptomatic. TB screening yield was 0.19% (48/25048) (95%CI, 0.14-0.25%) and it varied between 0 and 0.83% stratified by country of origin. Number needed to screen was 522. CONCLUSIONS: TB screening yield was higher as compared with data reported from other European countries conducting active screening among asylum seekers. Half of the TB cases among asylum seekers were first suspected in screening; 44% were asymptomatic. TB yield varied widely between asylum seekers from different geographic areas.

Asylum seekers health and wellbeing (TERTTU) survey: study protocol for a prospective total population health examination survey on the health and service needs of newly arrived asylum seekers in Finland.

INTRODUCTION: Health, well-being and health service needs of asylum seekers have emerged as urgent topics following the arrival of 2.5 million asylum seekers to the European Union (EU) between 2015 and 2016. However, representative information on the health, well-being and service needs of asylum seekers is scarce. The Asylum Seekers Health and Wellbeing (TERTTU) Survey aims to: (1) gather population-based representative information; (2) identify key indicators for systematic monitoring; (3) produce the evidence base for development of systematic screening of asylum seekers' health, well-being and health service needs. METHODS AND ANALYSIS: TERTTU Survey is a population-based prospective study with a total population sample of newly arrived asylum seekers to Finland, including adults and children. Baseline data collection is carried out in reception centres in 2018 and consists of a face-to-face interview, self-administered questionnaire and a health examination following a standardised protocol. Altogether 1000 asylum seekers will be included into the study. Baseline data will be followed up with national electronic health record data encompassing the entire asylum process and later with national register data among persons who receive residency permits. ETHICS AND DISSEMINATION: Ethical approval has been granted by the Coordinating Ethics Committee of the Helsinki and Uusimaa Hospital District. Participation is voluntary and based on written informed consent. Results will be widely disseminated on a national and international level to inform health and welfare policy as well as development of services for asylum seekers. Results of the study will constitute the evidence base for development and implementation of the initial health assessment for asylum seekers on a national level.

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.
