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.

Factors associated with access to dental care among refugees: A systematic review of quantitative studies

OBJECTIVES

To identify, appraise and synthesize the published evidence from quantitative studies on the individual and contextual-level factors determining access to dental care among refugees worldwide.

METHODS

A systematic literature search was conducted until the last week of February 2022 in four electronic databases - MEDLINE, Embase, Web of Science (all databases) and APA PsycINFO - without any restrictions. Quantitative studies published in English language and meeting the a priori eligibility criteria were reviewed and data extracted. Quality assessment was conducted using the National Institutes of Health tool. The identified factors were stratified according to the framework of the Behavioural Model of Health Services Use, and the evidence related to each of these factors was summarized in tables. Narrative synthesis of the findings was conducted.

RESULTS

The search retrieved 6776 unique records, of which 69 were deemed eligible for full-text screening and nine studies were included in the final data analysis and synthesis. The studies were rated to be of 'fair' quality at best. Self-reported previous dental visits was the most commonly used measure of access. Associations between individual-level factors and dental care access were most frequently examined (predisposing [n = 6], need [n = 2] and enabling [n = 1]), while the contextual-level factors were rarely examined (predisposing and enabling [n = 1, each]).

CONCLUSIONS

Individual-level predisposing factors, such as English language proficiency, education, health and dental literacy and acculturation and integration, were shown to be significantly associated with refugees' access. There is limited evidence to determine the effect of individual enabling and need and contextual factors.

'Fragmented care': Asylum seekers' experience of accessing health care in NSW

Medicare is central to accessing health care in Australia, yet many asylum seekers are ineligible for this scheme. In NSW, Medicare ineligible asylum seekers have some access to public health care under the Medicare Ineligible Asylum Seekers - Provision of Specified Public Health Services policy. This policy was updated in November 2020 to clarify services where a fee waiver applies for asylum seekers without Medicare. We examined the experiences of Medicare ineligible asylum seekers in accessing health care in New South Wales (NSW) in light of the revised policy. Employing qualitative methods, we conducted semi-structured interviews with asylum seekers (n = 7) and service providers (n = 6) in South Western Sydney. The interviews were analysed using thematic analysis and the socio-ecological model was used to interpret the data. Participants identified that chronic and mental health conditions are the main health issues for asylum seekers. Factors across the four levels of the socio-ecological model were identified as influencing the health care of asylum seekers, including a lack of awareness about health care rights at the individual level, support from relatives and friends at the interpersonal level, providers' lack of awareness of fee waivers at the organizational level and limited access to primary health care at the policy level. The results imply that Medicare ineligible asylum seekers in NSW do not have optimal access to health care which may worsen existing health disparities. Educational initiatives that improve service providers' and asylum seekers' awareness of the revised policy are needed to improve asylum seeker health equity in NSW.

Iron deficiency, anemia and association with refugee camp exposure among recently resettled refugees: A Canadian retrospective cohort study

Malnutrition and poor health are common among recently resettled refugees and may be differentially associated with pre-migration exposure to refugee camp versus non-camp dwelling. We aimed to investigate the associations of iron deficiency (ID), anemia, and ID anemia (IDA) with pre-migration refugee camp exposure among recently arrived refugees to Canada. To this end, we conducted a retrospective cohort study of 1032 adult refugees who received care between January 1, 2011, and December 31, 2015, within a specialized refugee health clinic in Calgary, Canada. We evaluated the prevalence, severity, and predictors of ID, anemia, and IDA, stratified by sex. Using multivariable logistic regression, we estimated the association of refugee camp exposure with these outcomes, adjusting for age, months in Canada prior to investigations, global region of origin, and parity. Among female refugees, the prevalence of ID, anemia, and IDA was 25% (134/534), 21% (110/534), and 14% (76/534), respectively; among males, 0.8% (4/494), 1.8% (9/494), and 0% (0/494), respectively. Anemia was mild, moderate, and severe in 55% (60/110), 44% (48/110) and 1.8% (2/110) of anemic females. Refugee camp exposure was not associated with ID, anemia, or IDA while age by year (ID OR = 0.96, 95% CI 0.93-0.98; anemia OR = 0.98, 95% CI 0.96-1.00; IDA OR = 0.96, 95% CI 0.94-0.99) and months in Canada prior to investigations (ID OR = 0.85, 95% CI 0.72-1.01; anemia OR = 0.81, 95% CI 0.67-0.97; IDA OR = 0.80, 95% CI 0.64-1.00) were inversely correlated with these outcomes. ID, anemia, and IDA are common among recently arrived refugee women irrespective of refugee camp exposure. Our findings suggest these outcomes likely improve after resettlement; however, given proportionally few refugees are resettled globally, likely millions of refugee women and girls are affected.

Epidemiology of Helicobacter pylori in Australia: a scoping review

Background

Helicobacter pylori (H. pylori), a bacterium implicated in the development of peptic ulcer and gastric cancer, is estimated to infect around half the world's population. Its prevalence in Australia is unclear. This scoping review aimed to evaluate all Australian literature providing estimates of the prevalence of H. pylori.

Methods

Australian studies examining H. pylori prevalence from 1982 onwards were eligible for inclusion. Medline, Embase and Scopus databases, and grey literature sources, were searched. Two independent reviewers undertook a two-stage screening process. Data were extracted by two independent reviewers using a pre-specified template.

Results

Of 444 identified studies, 75 were included in the review. H. pylori prevalence in Australian population-based studies (n = 8) ranged from 38.0% in 1991 to 15.1% in 2002; however, estimated prevalence across all non-clinical population studies in diverse sub-groups (n = 29) has varied dramatically. Decreased prevalence has been more marked in populations with gastrointestinal symptoms and conditions compared to non-clinical populations. Data on H. pyloriprevalence in vulnerable populations are lacking.

Conclusions

This is the first scoping review of Australian studies reporting H. pylori prevalence. A wide range of study designs, population groups, geographic regions, and diagnostic methods was included, involving data collected over a 50-year period (1969 to 2018). The summary of H. pylori prevalence estimates over time in this review points to a decrease in prevalence in Australia, particularly among populations with gastrointestinal symptoms and illnesses; however, it is unknown whether there is inequity in prevalence trends across vulnerable sub-groups of the Australian population. Future research and interventions supporting the health and wellbeing of vulnerable populations is required to ensure equitable health gains are made for all.

Health of African Refugee Children Outside Africa: A Scoping Review

PROBLEM

Africa is the largest source continent of refugee children. However, we found no published synthesis of the literature on the health of African refugee children outside Africa. Conducting a review of the literature on this particular population will help illuminate the particular contextual health issues faced by African child refugees who live outside Africa. The purpose of this review is to synthesize what is known from the existing literature regarding the health of sub-Saharan African refugee children who live outside Africa.

METHODS

We completed a scoping review of the published literature. We included articles published in English with a focus on the health of sub-Saharan African refugee children living outside Africa. We excluded studies of refugees in Africa as the living conditions of these refugees, most of whom reside in camps, are very different from those outside Africa. Using relevant keywords, we searched 10 databases to identify and screen 6602 articles after duplicates were eliminated.

SAMPLE

A total of 20 studies were included in this review.

FINDINGS

Published research articles on sub-Saharan African child refugees living outside Africa focus on infectious diseases, mental health and neurodevelopmental disorders, food insecurity and psychosocial adjustment, physical health (including obesity), and health promotion strategies. This population is characterized by a high rate of infectious diseases (e.g., malaria), obesity, and mental health problems, especially post-traumatic stress disorder (PTSD).

CONCLUSIONS AND IMPLICATIONS

To attend to the health needs of sub-Saharan African refugee children who live outside Africa, interventions should address pre-migration factors as well as post-migration factors (including income and community belonging) while employing a strengths-based perspective.

Burden of oral diseases and impact of protracted displacement: a cross-sectional study on Syrian refugee children in Lebanon

Introduction Very little is known about the burden of childhood oral diseases in protracted humanitarian settings.Aim This study aimed to assess the prevalence of oral diseases in Syrian refugee children living in Lebanon and to investigate their relationship with the duration of displacement.Methods Data from Miles for Smiles programme for Syrian refugee schoolchildren in Bekaa/Lebanon were used (n = 823). A dental examination was performed to assess the presence of dental caries and abscess. A clinical form was used to collect data on the presence, intensity and duration of dental pain.Results The majority (90%) had dental caries, 57% had dental pain (of which 55% had moderate/severe pain and 38% had pain for more than a month) and 9% had dental abscess. After adjusting for age and gender, children in protracted displacement were significantly more likely to have a higher number of decayed teeth compared to their counterparts who had been displaced for less than five years (RR = 1.19; 95% CI = 1.09-1.29; P <0.001).Conclusions The burden of oral diseases in Syrian refugee children living in Lebanon was high, particularly among those living in a protracted situation. There is a need for evidence-based effective public health interventions to improve this population's oral health.

In search of a "vocabulary for recreation": Leisure-time physical activity among humanitarian migrants in regional Australia

This study provides an exploration of the meanings of leisure for humanitarian migrants in regional Australia and these meanings' implications for health. It uses mixed-methods to explore leisure-time physical activity participation and day-to-day experiences of leisure and health. A sample representing approximately one third of the Coffs Coast adult humanitarian migrant population completed the survey, as well as 32 individuals who participated in interviews and focus groups. Findings were organised into three themes and explored issues around mental health and time for leisure, cultural differences in experiencing leisure, and the connections with experiences of other disadvantaged groups. We conclude by arguing that leisure needs to be brought to the fore of discussions around service provision and policy making concerned with the wellbeing of the refugee migrant population, particularly focusing on support for the (re)development of a vocabulary for recreation, as a step forward in the journey to healing and belonging.

Active and latent tuberculosis in refugees and asylum seekers: a systematic review and meta-analysis

Background

In 2018, there were 70.8 million refugees, asylum seekers and persons displaced by wars and conflicts worldwide. Many of these individuals face a high risk for tuberculosis in their country of origin, which may be accentuated by adverse conditions endured during their journey. We summarised the prevalence of active and latent tuberculosis infection in refugees and asylum seekers through a systematic literature review and meta-analyses by country of origin and host continent.

Methods

Articles published in Medline, EMBASE, Web of Science and LILACS from January 2000 to August 2017 were searched for, without language restriction. Two independent authors performed the study selection, data extraction and quality assessment. Random effect models were used to estimate average measures of active and latent tuberculosis prevalence. Sub-group meta-analyses were performed according to country of origin and host continent.

Results

Sixty-seven out of 767 identified articles were included, of which 16 entered the meta-analyses. Average prevalence of active and latent tuberculosis was 1331 per 100 thousand inhabitants [95% confidence interval (CI) = 542–2384] and 37% (95% CI = 23–52%), respectively, both with high level of heterogeneity (variation in estimative attributable to heterogeneity [I²] = 98.2 and 99.8%). Prevalence varied more according to countries of origin than host continent. Ninety-one per cent of studies reported routine screening of recently arrived immigrants in the host country; two-thirds confirmed tuberculosis bacteriologically. Many studies failed to provide relevant information.

Conclusion

Tuberculosis is a major health problem among refugees and asylum seekers and should be given special attention in any host continent. To protect this vulnerable population, ensuring access to healthcare for early detection for prevention and treatment of the disease is essential.

Catching up with catch-up: a policy analysis of immunisation for refugees and asylum seekers in Victoria

This study examines catch-up immunisation for people of refugee-like background in Victoria, exploring effective models of service delivery to complete catch-up vaccinations. The analysis is based on: (i) review of the medical literature, Commonwealth and Victorian government immunisation policy and immunisation patient information; (ii) review of vaccination coverage and service delivery data; and (iii) stakeholder interviews completed in 2014 with 45 people from 34 agencies, including 9 local government areas in Victoria. Although refugees and asylum seekers all need catch-up vaccinations on arrival, they face significant barriers to completing immunisation in Australia. Analysis suggests missed opportunities by service providers and perceptions that catch-up vaccination is time-consuming, difficult and resource-intensive. Service delivery is fragmented across primary care and local government, and pathways depend on age, location and healthcare access. There are strengths, but also limitations in all current service delivery models. Gaps in vaccine funding for refugee-like populations have now been addressed through Commonwealth initiatives, however migration is still not well considered in immunisation policy, and existing systems for notification payments do not capture catch-up vaccination for these groups. Providers identify areas for improvement in professional development and support, patient information, patient-held records and immunisation surveillance data.

Prevalence and Predictors of Vitamin D Deficiency among African Immigrants Living in Australia

Vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) concentrations <50 nmol/L) is a public health issue in Australia and internationally. Those with darker skin require a greater dose of ultraviolet B radiation from sunlight than those with paler skin to synthesise adequate amounts of vitamin D. Using data from the 2011-2013 Australian Health Survey, we investigated the prevalence and predictors of vitamin D deficiency in African immigrants aged ≥18 years living in Australia (n = 236). Serum 25(OH)D was measured using a liquid chromatography-tandem mass spectrometry method that is certified to international reference measurement procedures. Poisson regression was used to investigate independent predictors of vitamin D deficiency. A total of 36% of adults were vitamin D deficient (35% of men, 37% of women). The prevalence ratio (PR) of vitamin D deficiency decreased by 2% per year of age (PR 0.98; 95% CI (0.97, 0.99); p = 0.004) and was 1.6 times higher in those with low/sedentary, compared to moderate/high, physical activity levels (PR 1.64; 95% CI (1.12, 2.39); p = 0.011). The greatest risk was for those assessed during winter/spring compared with summer/autumn (PR 1.89; 95% CI (1.33, 2.64); p < 0.001). Culturally appropriate messaging on safe sun exposure and dietary vitamin D is warranted in order to promote vitamin D sufficiency in African immigrants living in Australia.

Challenges in health-care service use among Burmese refugees: A grounded theory approach

The timely use of health-care services is essential to achieve the best health outcomes. We explore barriers to health-care access among refugees from Burma through interviews with key community informants who serve their community as interpreters, health-care professionals, paraprofessionals, and/or representatives. The interviews with a convenience sampling of 11 leaders from Burmese and Karen ethnic communities revealed three stages of health-care use (i.e., before, during, and after doctor's appointments), in which their community members encounter difficulties in accessing health-care services. Using grounded theory analysis approach, specific difficulties and cultural considerations for each stage were emerged. This study suggests that training programs for health-care providers on refugee populations' needs, cultural expectations, attitudes, and health behaviors may ease the process for refugees during each of these three stages. Interpreters as cultural brokers have an important role in facilitating cross-cultural communications not only before and during the appointment but also after doctor's visits, such as in the pharmacy and labs.

A model explaining refugee experiences of the Australian healthcare system: a systematic review of refugee perceptions

Background

Refugees have significant unmet health needs. Delivering services to refugees continues to be problematic in the Australian healthcare system. A systematic review and thematic synthesis of the literature exploring refugee perceptions of the Australian healthcare system was performed.

Methods

Titles and abstracts of 1610 articles published between 2006 and 2019 were screened, and 147 articles were read in full text. Depending on the type of study, articles were appraised using the Modified Critical Appraisal Tool (developed by authors), the Mixed Methods Appraisal Tool, or the JBI Appraisal Checklist for Systematic Reviews. Using QSR NVivo 11, articles were coded into descriptive themes and synthesised into analytical themes. An explanatory model was used to synthesise these findings. Confidence in the review findings were assessed with GRADE-CERQual approach.

Results

The final synthesis included 35 articles consisting of one systematic review, 7 mixed methods studies, and 27 qualitative studies. Only one study was from a regional or rural area. A model incorporating aspects of engagement, access, trust, and privacy can be used to explain the experiences of refugees in using the Australian healthcare system. Refugees struggled to engage with health services due to their unfamiliarity with the health system. Information sharing is needed but this is not always delivered effectively, resulting in disempowerment and loss of autonomy. In response, refugees resorted to familiar means, such as family members and their pre-existing cultural knowledge. At times, this perpetuated their unfamiliarity with the broader health system. Access barriers were also encountered. Trust and privacy are pervasive issues that influenced access and engagement.

Conclusions

Refugees face significant barriers in accessing and engaging with healthcare services and often resorted to familiar means to overcome what is unfamiliar. This has implications across all areas of service provision. Health administrators and educators need to consider improving the cultural competency of staff and students. Policymakers need to consider engaging communities and upscale the availability and accessibility of professional language and cultural supports. Research is needed on how these measures can be effectively delivered. There is limited research in remote areas and further evidence is needed in these settings.

How can healthcare professionals address poor health service utilisation among refugees after resettlement in Australia? A narrative systematic review of recent evidence

This systematic narrative review of qualitative studies examined health service barriers and facilitators in Australia for refugees after resettlement. Twelve qualitative studies published between 2006 and 2017 involving more than 500 participants were included in the review. Approximately half of all participants were healthcare professionals. A meta-synthesis approach was used to compare and combine findings from across studies. Few facilitators were identified. Barriers to accessing health services were commonly attributed to refugees, but several barriers were associated with healthcare professionals and health services. Barriers attributed to healthcare professionals included gaps in knowledge and skills; poor cultural competency; poor communication skills; and time constraints. Understanding such barriers is the first step in developing strategies to overcome them. The skills and knowledge of healthcare professionals are important to facilitating access to healthcare among this vulnerable population.

An investigation into the association of pre- and post-migration experiences on the self-rated health status among new resettled adult humanitarian refugees to Australia: a protocol for a mixed methods study

BACKGROUND

Refugees are one of the most vulnerable groups in our society. They are at risk of poor physical and mental health outcomes, much of this attributed to traumatic events prior to migration and the additional risk factors refugees face in the host nations. However, how migration factors shape the health of resettling refugees is not well understood. This study uses a mixed methods approach to examine how pre- and post-migration factors shape the self-rated health of resettling adult refugees in an effort to address the current knowledge gap.

METHODS

This study will use a sequential explanatory mixed method study design. We begin by analyzing resettlement and health data from the 'Building a New Life In Australia' longitudinal study of humanitarian refugees resettled in Australia to identify significant associations between migration factors and refugee health. Then, a series of semi-structured interviews with resettled refugees will further explore the lived experiences of refugees with respect to the relationship between migration and refugee health. Finally, we will integrate both sets of findings to develop a detailed understanding of how and why migratory factors contribute to refugee health during resettlement.

DISCUSSION

There is a paucity of studies that examine the multidimensional nature of refugee health during resettlement and as a result, little is understood about their resettlement health needs. This information is required to inform existing or new resettlement interventions to help promote or improve refugee health. To overcome these limitations in the research knowledge, this study will use a mixture of study methods to illustrate the complex and multifaceted determinants of refugee health during resettlement in Australia.

Prevalence and Types of Anemia in a Large Refugee Cohort in Western Europe in 2015

Currently, vast numbers of migrants with largely unknown health statuses have been entering Europe. To improve care taking strategies, prevalence, severity and types of anemia in a large refugee cohort were assessed. Blood counts were performed in n = 787 inhabitants from six German refugee centers. Most included migrants were young, male adults. Anemia was present in 22.5% of subjects with an age-dependent prevalence increase (7.9% > 18 years vs. 30.8% > 50 years). More females than males were anemic (27.1% vs. 20.4%). The majority of affected migrants had mild anemia (86.2%) of either normocytic/normochromic (55.9%) or microcytic/hypochromic (20.9%) type. Observed anemia frequencies are in accordance with global anemia prevalence recently estimated by the WHO. However, the observed high rates of anemia particularly in female and older refugees emphasize the need for adapted care taking strategies in refugee medicine. Further evaluation of causes of anemia in the migrating population is needed.

A Community Standard: Equivalency of Healthcare in Australian Immigration Detention

The Australian government has long maintained that the standard of healthcare provided in its immigration detention centres is broadly comparable with health services available within the Australian community. Drawing on the literature from prison healthcare, this article examines (1) whether the principle of equivalency is being applied in Australian immigration detention and (2) whether this standard of care is achievable given Australia's current policies. This article argues that the principle of equivalency is not being applied and that this standard of health and healthcare will remain unachievable in Australian immigration detention without significant reform. Alternate approaches to addressing the well documented issues related to health and healthcare in Australian immigration detention are discussed.

Pharmacists in humanitarian crisis settings: Assessing the impact of pharmacist-delivered home medication management review service to Syrian refugees in Jordan

BACKGROUND

Refugees all over the world are facing several health-related problems. Chronic diseases among Syrian refugees in Jordan are high. The Home Medication Management Review (HMMR) service could be ideal to optimize refugees' health management.

OBJECTIVES

To assess the impact of the HMMR service on the type and frequency of Treatment Related Problems (TRPs) among Syrian refugees living in Jordan.

METHODS

This prospective randomized single blinded intervention-control study was conducted in three main cities in Jordan, between May and October 2016. Syrian refugees with chronic conditions were recruited and randomized into intervention and control groups. The HMMR service was conducted for all patients to identify TRPs at baseline. Data were collected via two home visits for all study participants. Clinical pharmacist's recommendations were written in a letter format to the physicians managing the patients in the intervention group only. Physicians' approved recommendations were conveyed to the patients via the pharmacist. Interventions at the patient level were delivered by the pharmacist directly. Patients were reassessed for their TRPs and satisfaction 3 months after baseline.

RESULTS

Syrian refugees (n = 106) were recruited with no significant differences between the intervention (n = 53) and control groups (n = 53). A total of 1141 TRPs were identified for both groups at baseline, with a mean number of 10.8 ± 4.2 TRPs per patient. At follow-up, there was a significant decrease in the number of TRPs among the intervention group (P < 0.001, paired sample t-test) but not among the control group (P = 0.116). Physicians' approval rate of the pharmacist's recommendations was high (82.9%), and more than 70.0% of refugees in the intervention group reported high satisfaction with the HMMR service.

CONCLUSION

Identified TRPs are high amongst Syrian refugees living in Jordan. The HMMR service significantly reduced the number of TRPs, and was highly accepted by the physicians. Refugees reported high satisfaction with this service.

Systematic health screening of refugees after resettlement in recipient countries: a scoping review

CONTEXT

Health screening of refugees after settlement in a recipient country is an important tool to find and treat diseases. Currently, there are no available reviews on refugee health screening after resettlement.

METHODS

A systematic literature search was conducted using the online Medical Literature Analysis and Retrieval System ('MEDLINE') database. Data extraction and synthesis were performed according to the PRISMA statement.

RESULTS

The search retrieved 342 articles. Relevance screening was conducted on all abstracts/titles. The final 53 studies included only original scientific articles on health screening of refugees conducted after settlement in another country. The 53 studies were all from North America, Australia/New Zealand and Europe. Because of differences in country policies, the screenings were conducted differently in the various locations. The studies demonstrated great variation in who was targeted for screening and how screening was conducted. The disease most frequently screened for was tuberculosis; this was done in approximately half of the studies. Few studies included screening for mental health and non-infectious diseases like diabetes and hypertension.

CONCLUSION

Health screening of refugees after resettlement is conducted according to varying local policies and there are vast differences in which health conditions are covered in the screening and whom the screening is available to.

The Australasian Society for Infectious Diseases and Refugee Health Network of Australia recommendations for health assessment for people from refugee-like backgrounds: an abridged outline

INTRODUCTION

In 2009, the Australasian Society of Infectious Diseases published guidelines on the post-arrival health assessment of recently arrived refugees. Since then, the number of refugees and asylum seekers reaching Australia has increased substantially (17 555 refugees in 2015-16) and the countries of origin have changed. These groups are likely to have had poor access to health care pre-arrival and, consequently, are at risk of a range of chronic and infectious diseases. We established an advisory group that included infectious diseases physicians, general practitioners, public health specialists, paediatricians and refugee health nurses to update the 2009 guidelines.Main recommendations: All people from refugee-like backgrounds, including children, should be offered a tailored comprehensive health assessment and management plan, ideally within 1 month of arrival in Australia. This can be offered at any time if initial contact with a GP or clinic is delayed. Recommended screening depends on history, examination and previous investigations, and is tailored based on age, gender, countries of origin and transit and risk profile. The full version of the guidelines is available at http://www.asid.net.au/documents/item/1225.Changes in management as a result of this guideline: These guidelines apply to all people from refugee-like backgrounds, including asylum seekers. They provide more information about non-communicable diseases and consider Asia and the Middle East as regions of origin as well as Africa. Key changes include an emphasis on person-centred care; risk-based rather than universal screening for hepatitis C virus, malaria, schistosomiasis and sexually transmissible infections; updated immunisation guidelines; and new recommendations for other problems, such as nutritional deficiencies, women's health and mental health.

Screening and Primary Care Access for Newly Arrived Paediatric Refugees in Regional Australia: A 5 year Cross-sectional Analysis (2007-12)

This study aimed to determine the prevalence of health conditions in newly arrived refugee children and access to timely heath screening. Methods: Cross-sectional data from screening of refugee children in regional Australia (2007-12) were analysed for health conditions and timeliness of primary care access. The health of 376 newly arrived refugee children (0-15 years) was assessed. Refugee children came from African (45%), Southeast Asian (29%) and Eastern Mediterranean (10%) regions. Access to primary care screening was present in 367 children (97% of arrivals). Completion of all recommended screening tests was 72%. Of 188 children with arrival and screening dates recorded, 88% were screened within 1 month and 96% within 6 months of arrival. Timely access of remaining children could not be assessed. Conclusion: Primary care was highly accessible to almost all newly arrived refugee children. Health screening was timely in those children with complete medical records.

Newly arrived refugee children with Helicobacter pylori are thinner than their non-infected counterparts

The hypothesis of this study was that those refugee children with Helicobacter pylori are thinner than their non-infected counterparts. This cross-sectional study investigated the height and weight of newly arrived refugee children up to age 19 years, who were screened for H. pylori using a stool antigen test at the Migrant Health Service in Adelaide between August 2010 and October 2013. Of 460 children, 21% were infected with H. pylori. After adjusting for vitamin B12 and iron levels, ethnicity, age and sex, the odds of being thin in the 10- to 19-year-old age group was 4.28-fold higher (95% CI 1.48–12.4) if they were H. pylori positive compared with those who were H. pylori negative. The difference between the two groups is statistically significant (P=0.01). Screening and treatment for H. pylori in the general population in developed countries is not recommended unless there are symptoms such as dyspepsia or risk of peptic ulcer, duodenal ulcer or gastric cancer. Given the findings of this study, a recommendation could be made that newly arrived refugee children who are thin should be tested for H. pylori. Thinness in children may influence their cognitive ability, school performance, physical endurance and hence their ability to successfully settle into their new country.

Addressing migration-related social and health inequalities in Australia: call for research funding priorities to recognise the needs of migrant populations

OBJECTIVE

Migrants constitute 26% of the total Australian population and, although disproportionately affected by chronic diseases, they are under-represented in health research. The aim of the present study was to describe trends in Australian Research Council (ARC)- and National Health and Medical Research Council (NHMRC)-funded initiatives from 2002 to 2011 with a key focus on migration-related research funding.

METHODS

Data on all NHMRC- and ARC-funded initiatives between 2002 and 2011 were collected from the research funding statistics and national competitive grants program data systems, respectively. The research funding expenditures within these two schemes were categorised into two major groups: (1) people focused (migrant-related and mainstream-related); and (2) basic science focused. Descriptive statistics were used to summarise the data and report the trends in NHMRC and ARC funding over the 10-year period.

RESULTS

Over 10 years, the ARC funded 15 354 initiatives worth A$5.5 billion, with 897 (5.8%) people-focused projects funded, worth A$254.4 million. Migrant-related research constituted 7.8% of all people-focused research. The NHMRC funded 12399 initiatives worth A$5.6 billion, with 447 (3.6%) people-focused projects funded, worth A$207.2 million. Migrant-related research accounted for 6.2% of all people-focused initiatives.

CONCLUSIONS

Although migrant groups are disproportionately affected by social and health inequalities, the findings of the present study show that migrant-related research is inadequately funded compared with mainstream-related research. Unless equitable research funding is achieved, it will be impossible to build a strong evidence base for planning effective measures to reduce these inequalities among migrants.

Refugee child oral health

The number of people forced to flee their homes and move around the world is increasing rapidly. Such refugee populations are not only more likely to have poor physical, mental and social health outcomes but also to experience difficulties accessing health services in their new country. In particular, children from refugee backgrounds are at increased risk of poor oral health which in time is associated with poor adult oral health and impacts on child health (e.g. growth and development) and well-being. To date, there is little evidence about the nature and extent of their oral health problems nor interventions to improve their oral health status. This article summarises the evidence surrounding the oral health status of children from refugee backgrounds. In addition, a systematic review of the international literature over the past 10 years is presented which identifies interventions to improve the oral health of these vulnerable paediatric populations. Based on this evidence, potential strategies available to dental service providers to optimise provision of responsive dental care are discussed.

Addressing inequities in alcohol consumption and related harms

Social determinants, or the conditions in which individuals are born, grow, live, work and age, can result in inequities in health and well-being. However, to-date little research has examined alcohol use and alcohol-related problems from an inequities and social determinants perspective. This study reviewed the evidence base regarding inequities in alcohol consumption and alcohol-related health outcomes in Australia and identified promising approaches for promoting health equity. Fair Foundations: the VicHealth framework for health equity was used as an organizing schema. The review found that social determinants can strongly influence inequities in alcohol consumption and related harms. In general, lower socioeconomic groups experience more harm than wealthier groups with the same level of alcohol consumption. While Australia has implemented numerous alcohol-related interventions and policies, most do not explicitly aim to reduce inequities, and some may inadvertently exacerbate existing inequities. Interventions with the greatest potential to decrease inequities in alcohol consumption and alcohol-related harms include town planning, zoning and licensing to prevent disproportionate clustering of outlets in disadvantaged areas; interventions targeting licensed venues; and interventions targeting vulnerable populations. Interventions that may worsen inequities include national guidelines, technological interventions and public drinking bans. There is a need for further research into the best methods for reducing inequities in alcohol consumption and related harms.

Understanding quality use of medicines in refugee communities in Australian primary care: a qualitative study

BACKGROUND

Although refugee health issues are increasingly experienced in primary health care, few studies have explored the quality use of medicines in refugee communities even though access to and quality use of medicines is a key component of care delivery.

AIM

To identify strategies to support the quality use of medicines in refugee communities.

DESIGN AND SETTING

Qualitative study with primary healthcare providers and refugee health leaders in Brisbane, Australia.

METHOD

Semi-structured interviews were conducted with refugee health leaders, pharmacists, practice nurses, and GPs. Data were recorded and transcribed. Thematic analysis was used to identify key barriers and facilitators for the quality use of medicines.

RESULTS

Five barriers, including communication and language barriers, limited health literacy and financial cost, and four facilitators, including better coordination between healthcare providers and improved healthcare provider training, were identified. This study provides a rich exploration relating to medication use and examines the engagement between pharmacists and refugees, highlighting some communication concerns. It recognises the supportive role of the practice nurse and offers practical strategies for improving community knowledge about safe medicines use.

CONCLUSION

This preliminary study builds on previous studies investigating refugee health access and health literacy. It offers new understandings towards enhancing quality use of medicines in refugee communities and practical insights to assist the targeting of resources for future interventions.

Maternal health and pregnancy outcomes comparing migrant women born in humanitarian and nonhumanitarian source countries: a retrospective, observational study

BACKGROUND

The relationship between migration and pregnancy outcomes is complex, with little insight into whether women of refugee background have greater risks of adverse pregnancy outcomes than other migrant women. This study aimed to describe maternal health, pregnancy care, and pregnancy outcomes among migrant women from humanitarian and nonhumanitarian source countries.

METHODS

Retrospective, observational study of singleton births, at a single maternity service in Australia 2002-2011, to migrant women born in humanitarian source countries (HSCs, n = 2,713) and non-HSCs (n = 10,606). Multivariable regression analysis assessed associations between maternal HSC-birth and pregnancy outcomes.

RESULTS

Compared with women from non-HSCs, the following were more common in women from HSCs: age < 20 years (0.6 vs 2.9% p < 0.001), multiparity (51 vs 76% p < 0.001), body mass index (BMI) ≥ 25 (38 vs 50% p < 0.001), anemia (3.2 vs 5.9% p < 0.001), tuberculosis (0.1 vs 0.4% p = 0.001), and syphilis (0.4 vs 2.5% p < 0.001). Maternal HSC-birth was independently associated with poor or no pregnancy care attendance (OR 2.5 [95% CI 1.8-3.6]), late first pregnancy care visit (OR 1.3 [95% CI 1.1-1.5]), and postterm birth (> 41 weeks gestation) (OR 2.5 [95% CI 1.9-3.4]). Stillbirth (0.8 vs 1.2% p = 0.04, OR 1.5 [95% CI 1.0-2.4]) and unplanned birth before arrival at the hospital (0.6 vs 1.2% p < 0.001, OR 1.3 [95% CI 0.8-2.1]) were more common in HSC-born women but not independently associated with maternal HSC-birth after adjusting for age, parity, BMI and relative socioeconomic disadvantage.

CONCLUSIONS

These findings suggest areas where women from HSCs may have additional needs in pregnancy compared with women from non-HSCs. Refugee-focused strategies to support engagement in pregnancy care and address maternal health needs would be expected to improve health outcomes in resettlement countries.

Australia's treatment of refugee and asylum seeker children: the views of Australian paediatricians

OBJECTIVE

Australia's response to refugees and people seeking asylum is a matter of national debate. We sought to determine the knowledge and attitudes of paediatricians about refugee and asylum seeker issues (both onshore and offshore).

DESIGN, SETTING AND PARTICIPANTS

In November 2013, we emailed a questionnaire web link to all Australian general and community paediatricians registered with the Royal Australasian College of Physicians.

MAIN OUTCOME MEASURES

Proportion of respondents by demographic characteristics using χ(2) and Fisher exact test (α = 0.05).

RESULTS

There were 139 respondents (response rate, 40.5%). Respondents' characteristics were broadly representative of all Australian general paediatricians. Over 80% correctly used the term "asylum seeker" rather than "boat person" or "illegal immigrant" for children applying for protection. Over 80% agreed with the Australian Medical Association assertion that mandatory detention of children constitutes child abuse, and disagreed with offshore processing. Less than half knew which subgroups were eligible for Medicare or had had pre-departure HIV and tuberculosis screening tests; or that the average stay in refugee camps before settlement in Australia was more than 10 years. Only about 60% knew that the Minister for Immigration and Citizenship was the legal guardian of detained unaccompanied minors. One in eight knew about the Medicare eligibility hotline. Respondents' sex, where their medical degree was obtained, frequency of seeing refugees and asylum seekers and years of experience had little association with responses.

CONCLUSIONS

Australian paediatricians considered mandatory detention a form of child abuse and strongly disagreed with offshore processing. There is a clear need for education about practical issues such as current health screening practices and Medicare eligibility.

Use of country of birth as an indicator of refugee background in health datasets

BACKGROUND

Routine public health databases contain a wealth of data useful for research among vulnerable or isolated groups, who may be under-represented in traditional medical research. Identifying specific vulnerable populations, such as resettled refugees, can be particularly challenging; often country of birth is the sole indicator of whether an individual has a refugee background. The objective of this article was to review strengths and weaknesses of different methodological approaches to identifying resettled refugees and comparison groups from routine health datasets and to propose the application of additional methodological rigour in future research.

DISCUSSION

Methodological approaches to selecting refugee and comparison groups from existing routine health datasets vary widely and are often explained in insufficient detail. Linked data systems or datasets from specialized refugee health services can accurately select resettled refugee and asylum seeker groups but have limited availability and can be selective. In contrast, country of birth is commonly collected in routine health datasets but a robust method for selecting humanitarian source countries based solely on this information is required. The authors recommend use of national immigration data to objectively identify countries of birth with high proportions of humanitarian entrants, matched by time period to the study dataset. When available, additional migration indicators may help to better understand migration as a health determinant. Methodologically, if multiple countries of birth are combined, the proportion of the sample represented by each country of birth should be included, with sub-analysis of individual countries of birth potentially providing further insights, if population size allows. United Nations-defined world regions provide an objective framework for combining countries of birth when necessary. A comparison group of economic migrants from the same world region may be appropriate if the resettlement country is particularly diverse ethnically or the refugee group differs in many ways to those born in the resettlement country.

SUMMARY

Routine health datasets are valuable resources for public health research; however rigorous methods for using country of birth to identify resettled refugees would optimize usefulness of these resources.

Control of iron deficiency anemia in low- and middle-income countries

Despite worldwide economic and scientific development, more than a quarter of the world’s population remains anemic, and about half of this burden is a result of iron deficiency anemia (IDA). IDA is most prevalent among preschool children and women. Among women, iron supplementation improves physical and cognitive performance, work productivity, and well-being, and iron during pregnancy improves maternal, neonatal, infant, and even long-term child outcomes. Among children, iron may improve cognitive, psychomotor, and physical development, but the evidence for this is more limited. Strategies to control IDA include daily and intermittent iron supplementation, home fortification with micronutrient powders, fortification of staple foods and condiments, and activities to improve food security and dietary diversity. The safety of routine iron supplementation in settings where infectious diseases, particularly malaria, are endemic remains uncertain. The World Health Organization is revising global guidelines for controlling IDA. Implementation of anemia control programs in developing countries requires careful baseline epidemiologic evaluation, selection of appropriate interventions that suit the population, and ongoing monitoring to ensure safety and effectiveness. This review provides an overview and an approach for the implementation of public health interventions for controlling IDA in low- and middle-income countries, with an emphasis on current evidence-based recommendations.
