Climate change, human migration and health nexus: what do we know about public health implications on a global scale?

OBJECTIVE: to address the nexus among climate change, migration, and health at global and Italian levels. DESIGN: narrative review. SETTING AND PARTICIPANTS: comprehensive, critical, and objective analysis of the current knowledge on the topic by searching online databases. MAIN OUTCOME MEASURES: evidence from the literature examining health issues associated with migration in the context of climate change. RESULTS: anthropogenic climate change has recently influenced the scale and patterns of human mobility, not only as a driver of migration, but also by interacting with and amplifying the effects of migration determinants, including health determinants. Despite research focusing on the distinct relationship between climate change and migration, as well as climate change and health, little attention has been paid to the nexus among climate change, migration, and health. Evidence available examining various health issues associated with migration in the context of climate change include changing patterns of infectious diseases and their risks, rising cases of malnutrition, trauma and injuries, changing patterns of noncommunicable diseases, impact on mental health. Inadequacy of access to health services due to the weakening and overstretching health systems also plays an important role. In a country like Italy, even if the immediate threats posed by climate change differ from one area to another, these threats are already exacerbating the country's existing infrastructure deficiencies, industrial pollution, and hydrogeological and seismic vulnerability. In addition, Italy has historically been a destination country of immigrant afflux through different migration routes. It is possible that the consequences of climate change in Sub-Saharan Africa will drive a growing number of people to cross the sea to reach Europe, specifically Italy. Conclusions: climate change, human migration, and health should be considered as an interconnected and complex issue. A shift to climate resilient health systems' is a useful precautionary measure as it aims to strengthen multiple aspects of national and sub-national health systems, regardless of the extent to which climate-related migration might occur.

Defining drivers of under-immunization and vaccine hesitancy in refugee and migrant populations.

BACKGROUND/OBJECTIVE: Some refugee and migrant populations globally showed lower uptake of COVID-19 vaccines and are also considered to be an under-immunized group for routine vaccinations. These communities may experience a range of barriers to vaccination systems, yet there is a need to better explore drivers of under-immunization and vaccine hesitancy in these mobile groups. METHODS: We did a global rapid review to explore drivers of under-immunization and vaccine hesitancy to define strategies to strengthen both COVID-19 and routine vaccination uptake, searching MEDLINE, Embase, Global Health PsycINFO and grey literature. Qualitative data were analysed thematically to identify drivers of under-immunization and vaccine hesitancy, and then categorized using the 'Increasing Vaccination Model'. RESULTS: Sixty-three papers were included, reporting data on diverse population groups, including refugees, asylum seekers, labour migrants and undocumented migrants in 22 countries. Drivers of under-immunization and vaccine hesitancy pertaining to a wide range of vaccines were covered, including COVID-19 (n = 27), human papillomavirus (13), measles or Measles-mumps-rubella (MMR) (3), influenza (3), tetanus (1) and vaccination in general. We found a range of factors driving under-immunization and hesitancy in refugee and migrant groups, including unique awareness and access factors that need to be better considered in policy and service delivery. Acceptability of vaccination was often deeply rooted in social and historical context and influenced by personal risk perception. CONCLUSIONS: These findings hold direct relevance to current efforts to ensure high levels of global coverage for a range of vaccines and to ensure that marginalized refugee and migrant populations are included in the national vaccination plans of low-, middle- and high-income countries. We found a stark lack of research from low- and middle-income and humanitarian contexts on vaccination in mobile groups. This needs to be urgently rectified if we are to design and deliver effective programmes that ensure high coverage for COVID-19 and routine vaccinations.

Framework for refugee and migrant health research in the WHO European Region.

Migration is a longstanding, growing global phenomenon. As a social determinant of health, migration can lead to health inequities between people on the move and host populations. Thus, it is imperative that there is a coordinated effort to advance migration- and health-related goals. WHO has a specific remit to support evidence-based decision-making in its Member States. As part of that remit, WHO Europe presents this Framework for Refugee and Migrant Health Research in the WHO European Region. It is designed as a starting point for debating and analysing a broad range of options and approaches to help inform a WHO global research agenda on health and migration. This is important because refugee and migrant health research is a complex interdisciplinary field that is expanding in a fast-changing socio-political environment. The Framework is intended for all stakeholders involved: academic, civil society organisations, refugees, migrants, policy-makers, healthcare providers, educators and funders. It is developed by academics in consultation with these stakeholder groups. It reflects on three specific interrelated dynamics in research practice. These are (i) research prioritisation; (ii) study samples and (iii) research design. The Framework offers recommendations to consider for each one of these. It elucidates the value of involving refugees and migrants in research and research agendas and the need to develop an ecosystem that will support and sustain participatory, interdisciplinary, transdisciplinary and inter-sectoral projects.

Ensuring Equitable Access to the COVID-19 Vaccine: The Experience of A Local Health Unit in Rome, Italy.

Growing evidence is emerging on the higher risk of infection and adverse outcomes for the most disadvantaged groups of the population, and COVID-19 vaccination campaigns worldwide are struggling to ensure equitable access to immunization for all. From 21 June 2021 to 15 October 2021, the Local Health Unit ASL Roma 1 adopted a tailored immunization strategy to reach socially vulnerable groups of the population with the primary vaccination course. This strategy was developed with a step-by-step, participatory approach. Through engagement with internal and external stakeholders, target groups were identified, potential barriers analyzed, solutions discussed, and tailored interventions designed. Over nine thousand individuals from among irregular migrants, homeless people and hard-to-reach communities were contacted and vaccinated.

Sharing country experiences: The WHO Global School on Refugee and Migrant Health in Jordan.

In 2021, Jordan was the first country to host the Global School for Refugee and Migrant Health, to improve the knowledge of the public health implications of migration. These perspective articles aim to retrieve salient reflections during the School as a baseline for further enhancement of migrant and health programs. During the School, a compilation of achievements, challenges, and opportunities was discussed around specific interrelated subjects, such as health system management and mental health. Successful examples were provided in the integration of refugees and migrants into health policies. On the other hand, the national health information systems are often not migrant-sensitive and evidence is still poor around mental health problems of refugees and migrants. Health financing remains a critical subject to address in a tailored way. The School highlighted the need to continue the exchange of experiences to promote a common approach to tackle similar needs.

Meeting the health needs of displaced people fleeing Ukraine: Drawing on existing technical guidance and evidence.

The invasion of Ukraine has unleashed a humanitarian crisis and the impact is devastating for millions displaced in Ukraine and for those fleeing the country. Receiving countries in Europe are reeling with shock and disbelief and trying at the same time to grapple with the reality of providing for a large, unplanned, unprecedented number of refugees mainly women and children on the move. Several calls for actions, comments and statements express outrage, the risks, and the impending consequences to life and health. There is a need to constantly assess the situation on the ground, identify priorities for health and provide guidance regarding how these needs could be addressed. Therefore, the Lancet Migration European Regional Hub conducted rapid interviews with key informants to identify these needs, and in collaboration with the World Health Organization Health and Migration Programme, summarized how these could be addressed. This viewpoint provides a summary of the situation in receiving countries and the technical guidance required that could be useful for providing assistance in the current refugee crisis.

Migrants' involvement in health policy, service development and research in the WHO European Region: A narrative review of policy and practice.

OBJECTIVES: The involvement of individuals and communities in health decision-making is enshrined in WHO policies. However, migrant groups are under-represented in health decision-making processes. Our aim was to explore migrants' involvement in health policy, service development and research in the WHO European Region to identify levers for inclusive and meaningful practice. METHODS: We conducted a narrative review of grey literature and peer-reviewed research on migrants' involvement in health decision-making across the 53 countries in WHO Europe. We searched for articles published in English between 2010 and the present in two electronic databases (PubMed, Scopus), IOM MIPEX Health Strand country reports, the EU SOPHIE project and using a Google advanced search. Findings were analysed descriptively and using Normalisation Process Theory to investigate levers and barriers to implementation of policy into practice. RESULTS: Of 1,444 articles retrieved, 79 met the inclusion criteria. We identified 20 policies promoting migrants' involvement, but national-level policies were present in only two countries. We identified 59 examples of migrants' involvement in practice from half of the WHO Europe countries (n = 27). Our Normalisation Process Theory (NPT) analysis of 14 peer-reviewed empirical papers found that participatory research approaches are a lever to putting policy into practice in a meaningful way. CONCLUSIONS: Migrants' involvement in health decision-making requires explicit national policies that are implemented evenly across policymaking, service provider and research activities in all countries in the WHO European Region. Participatory approaches to involvement activities are encouraged because they are a lever to perceived barriers to migrants' involvement.

Migrant health in Italy: a better health status difficult to maintain-country of origin and assimilation effects studied from the Italian risk factor surveillance data.

BACKGROUND: Many studies on migrant health have focused on aspects of morbidity and mortality, but very few approach the relevant issues of migrants' health considering behavioral risk factors. Previous studies have often been limited methodologically because of sample size or lack of information on migrant country of origin. Information about risk factors is fundamental to direct any intervention, particularly with regard to non-communicable diseases that are leading causes of death and disease. Thus, the main focus of our analysis is the influence of country of origin and the assimilation process. METHOD: Utilizing a surveillance system that has been collecting over 30,000 interviews a year in Italy since 2008, we have studied migrants' attitudes and behaviors by country of origin and by length of stay. Given 6 years of observation, we have obtained and analyzed 228,201 interviews of which over 9000 were migrants. RESULTS: While migrants overall present similar conditions to native-born Italians, major differences appear when country of origin or length of stay is considered. Subgroups of migrants present substantially different behaviors, some much better than native-born Italians, some worse. However, integration processes generally produce a convergence towards the behavioral prevalence observed for native-born Italians. CONCLUSIONS: Health programs should consider the diversity of the growing migrant population: data and analyses are needed to support appropriate policies. Many migrants' subgroups arrive with healthier behaviors than those of their adopted country. However, they are likely to have a less favorable social position in their destination countries that could lead to a change towards less healthy behaviors. Interventions capable of identifying this tendency could produce significant better health for this important part of the future (multicultural) populations.

How can we further rights-based and evidence-based policies on migrant and ethnic minority health?

There is an urgent need to draw the attention of politicians and the public to the health inequities facing migrants and ethnic minorities to foster health policy reforms based on human rights and sound evidence. Today, it is more important than ever for researchers and organisations promoting migrant health to join forces and intensify their efforts to get policies improved. A workshop was held to consider how this should be done. Three speakers put forward in turn perspectives based mainly on human rights, scientific evidence and a combination of both.

Migrant health research in the Republic of Ireland: a scoping review.

BACKGROUND: Migration to European countries has increased in number and diversity in recent years. Factors such as access to healthcare, language barriers and legal status can impact the health outcomes of migrant groups. However, little is known about the evidence base on the health status of migrants in the Republic of Ireland. Our aim was to scope existing peer-reviewed research on the health of migrants in Ireland and identify any gaps in the evidence. METHODS: We conducted a scoping review of peer-reviewed research on the health of migrants in the Republic of Ireland. Eleven electronic databases were searched for peer-reviewed, empirical articles published between 2001 and 2017. Search terms were adapted from a World Health Organisation review. Findings were analysed using the 2016 World Health Organisation Strategy and Action Plan for Refugee and Migrant Health in the World Health Organisation European region, which outlines nine strategic areas that require collaborative action. RESULTS: Of 9396 articles retrieved, 80 met inclusion criteria, with the majority (81%) published since 2009. More than half of the studies had a quantitative design (65%). Migrants studied came from Eastern Europe, Asia and Africa and included labour migrants, refugees and asylum seekers. Most studies related to two World Health Organisation strategic areas; 4: "achieving public health preparedness and ensuring an effective response", and 5: "strengthening health systems and their resilience". CONCLUSION: There is growing attention to migrant health in Ireland with a balance of qualitative and quantitative research. While much of the identified research is relevant to three of the World Health Organisation strategic areas, there are significant gaps in the other six areas. The study design could be replicated in other countries to examine and inform migrant health research.

What constitutes an effective and efficient package of services for the prevention, diagnosis, treatment and care of tuberculosis among refugees and migrants in the WHO European Region?

The WHO European Region has faced high rates of external and internal migration in recent years, with concerns that this is contributing to the burden of tuberculosis (TB), multidrug-resistant TB (MDR-TB) and TB/HIV coinfection in some countries. This report examines evidence of effective and efficient service packages for the prevention, diagnosis and treatment of TB to inform strategies to address the TB burden in refugee and migrant populations. Significant regional variations were identified in both migration levels and TB burden in refugees and migrants, as well as in approaches to TB control, with low quality of evidence in many cases. While it is unlikely that a single strategy/package will be effective for all situations, the evidence highlights some common approaches that could guide policy-making and service development. TB elimination targets for the Region will not be met unless inequalities in access to screening and treatment for migrants are addressed, alongside efforts to tackle TB globally.

What strategies to address communication barriers for refugees and migrants in health care settings have been implemented and evaluated across the WHO European Region?

The provision of effective health care to linguistically and culturally diverse migrant populations has been identified as a crucial public health issue. This scoping review examines strategies that have been implemented and evaluated to address communication barriers experienced by refugees and migrants in health care settings across the WHO European Region. Four main types of strategy were identified: cultural mediation, interpretation, translation of health information, and guidance and training for health care providers. These have been used to support access to health care, management of specific diseases and promotion of health across a wide variety of health care settings. Intersectoral collaboration was seen as important in the development and implementation of strategies. Policy considerations include the development of national policies and the promotion of intersectoral dialogue to augment the knowledge base and resolve the common issues identified, such as provision of training and confusion regarding the roles of mediators/interpreters, that affect strategy implementation and evaluation.
