Health of refugees settled in Australia over time and generations: a transformative mixed methods study protocol. BMJ Open 2024; 14:e083454. [PMID: 39306348 PMCID: PMC11418575 DOI: 10.1136/bmjopen-2023-083454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 09/04/2024] [Indexed: 09/25/2024] Open
Abstract
BACKGROUND Refugees resettled in Australia may experience significant physical, mental and emotional health issues on arrival and difficulty accessing mainstream healthcare that often demands specialised services. It is not known if and how refugee health needs and service use change over time and generations, how this compares with the broader Australian population and what level of resourcing is required to maintain specialised services. There is also a significant knowledge gap concerning the resources and skills of refugees that can be harnessed to sustain the health and well-being of individuals and communities. Such knowledge gaps impede the ability of the health system to deliver responsive, efficient, acceptable and cost-effective care and services and limit the engagement of refugees in the coproduction of these services. METHODS This study will be the first to provide comprehensive, longitudinal, population-based evidence of refugee health, service use and the accumulated resources or assets related to positive health and well-being (compared with data on deficits, illness and death) across the lifespan and generations. This will enable a comprehensive understanding of the relationships among assets, health status, service gaps and behaviours. We will identify the assets contributing to increased capacities to protect and promote health. This evidence is essential for planning health prevention programmes.This project has three phases: (1) employ national linked datasets to examine the health and social outcomes of refugees in Australia; (2) engage with refugees in a participatory manner to map the social, economic, organisational, physical and cultural assets in their communities and deliver an integrated model of health; and (3) codesign a roadmap of agreed actions required to attain health and well-being in communities and indicators to assess outcomes. ETHICS AND DISSEMINATION Ethics and procedures-phase I:Ethical approval for phase I was gained from the Australian Bureau of Statistics (ABS) for Person Level Integrated Data Asset microdata (unit record data) via the ABS DataLab and the NSW Population and Health Services Research Ethics Committee (2023ETH01728), which can provide a single review of multijurisdictional data linkage research projects under the National Mutual Acceptance Scheme. This will facilitate approval for the Victorian and ACT datasets. The ABS will be the integrating/linkage authority. The Centre for Health Record Linkage (CHeReL) and the Victorian Data Linkage Unit will prepare a data extract representing all data records from the dataset to provide to the ABS for linkage.Ethics and procedures-phases 2 and 3:Written consent will be obtained from all participants, as well as consent to publish. We have obtained ethical approval from the University of Technology Sydney Medical Research Ethics Committee; however, as we deepen our consultation with community members and receive input from expert stakeholders, we will likely seek amendments to hone the survey and World Café questions. We will also need to provide flexible offerings that may extend to individual interviews and online interactions. DISCUSSION This innovative approach will empower refugees and put them at the centre of their health and decision-making.

Abstract
Purpose We aimed to compare cancer mortality among foreign- and Colombian populations in Colombia during the period of 2006-2020. Methods This retrospective study utilized vital statistics from the Colombian National Department of Statistics (DANE). The dataset included variables such as age group, sex, country of permanent residency, insurance, education level, marital status, ethnicity, and cause of death. The population data to calculate rates was obtained from the Colombian census and the United Nations. Crude and adjusted rates as well as proportional mortality rates were calculated. Results A total of 561,932 cancer deaths occurred in Colombia from 2006 to 2020. The foreign population (country of permanent residency different to Colombia) had a lower crude cancer mortality rate (31.1 per 100,000 inhabitants) than the Colombian population (81.9 per 100,000 inhabitants). However, the age-adjusted cancer mortality rate among the foreign population was 253.6 per 100,000, compared to 86.1 per 100,000 among the Colombian population. The proportional cancer mortality was 10.4 % among foreign population compared to 17.4 % among Colombian population. Conclusions The proportional cancer mortality shows that the proportion of cancer-related deaths is greater among the Colombian population compared to the immigrant population. However, immigrants in Colombia have a higher age-adjusted cancer mortality rate than Colombians, indicating that immigrants have worse cancer outcomes than the Colombians even though the immigrant population is younger. This is likely due to the frequent barriers that immigrants encounter in accessing health care in Colombia. Future research needs to focus on access to care for the immigrant population by investigating cancer-related risk factors among immigrants and addressing their barriers to cancer prevention and treatment.

Abstract
Objective To compare treatment within 12 months of diagnosis, and survival by country of birth for people diagnosed with invasive non-small cell lung cancer (NSCLC) in New South Wales (NSW), Australia.
Design, patients, and setting A population-based cohort study of NSW residents diagnosed with NSCLC in 2003–2016 using de-identified linked data from the NSW Cancer Registry, NSW Admitted Patient Data collection, Emergency Departments, Medicare Benefits and Pharmaceutical Benefits Scheme, and National Death Index. Main outcome measures Odds of receiving any treatment, surgery, systemic therapy, or radiotherapy respectively, in the 12 months following diagnosis were calculated using multivariable logistic regression. The hazard of death (all-cause) at one- and five-years following diagnosis was calculated using multivariable proportional hazards regression. Results 27,114 People were recorded with NSCLC in the 14-year study period. Higher percentages of older males from European countries applied in the earlier years, with a shift to younger people from South East Asia, New Zealand, and the Middle East. Adjusted analyses indicated that, compared with the Australian born, people from European countries were more likely to receive treatment, and, specifically surgery. Also, people from Asian countries were more likely to receive systemic therapy but less likely to receive radiotherapy. Survival at one- and five-years following diagnosis was higher for people born in countries other than Australia, New Zealand the United Kingdom and Germany. Conclusions Variations exist in treatment and survival by country of birth in NSW. This may be affected by differences in factors not recorded in the NSW Registry, including use of general health services, family histories, underlying health conditions, other intrinsic factors, and cultural, social, and behavioural influences.

Abstract
INTRODUCTION Cancer care and outcomes differ across cultural groups in Australia. Quantifying these differences facilitates prioritisation and targeting of services and research. All-of-population data are needed by health agencies to understand and fulfil their cancer-control responsibilities. Compiling these data can be challenging while maintaining privacy. We have used data linkage to gain population-wide colorectal cancer data on stage (degree of spread), treatment, and survival in New South Wales (NSW), Australia, by country of birth (COB), and consider service implications. METHODS We studied colon and rectal cancers diagnosed in 2003-2016 and recorded on the NSW Cancer Registry (n = 41,575), plus linked hospital data and data from Australian Medical and Pharmaceutical Benefits payments, other treatment data and death records. Outcomes for 12 COB categories were analysed using multiple logistic and proportional hazards regression, with Australia as the reference category. RESULTS Compared with Australian born, the adjusted odds ratio for distant spread of colon cancer was higher for people born in Lebanon and the United Kingdom. Treatment was less common for people born in China (surgery), Germany (systemic), Italy (surgery), New Zealand (any treatment) and Vietnam (all treatments), while treatment for rectal cancer was more common for people born in Italy (surgery), United Kingdom (radiotherapy, systemic therapy), and Vietnam (surgery), and less frequent for people born in China (radiotherapy). Adjusted 5-year survival was higher for people born in China, Italy, Vietnam, Greece (colon), Lebanon (colon) and other non-English speaking countries. More advanced stage was negatively related to having surgery and survival. CONCLUSIONS This study illustrates how linked data can enable comparisons of multiple outcomes for colorectal cancer by country of birth across an entire population. Results disclose "big picture" variations in population characteristics, stage, treatment and survival. This will enable better targeting and prioritisation of services and inform research priorities to address disparities.

[PMID: 35322272 PMCID: PMC9306400 DOI: 10.1158/1055-9965.epi-21-1349] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 02/08/2022] [Accepted: 03/07/2022] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Australia provides an ideal population-base for cancer migration studies because of its multicultural society and high-quality cancer registrations. Among migrant groups there is considerable variability in the incidence of infection-related cancers; thus, the patterns of three such cancers were examined among migrant groups relative to Australian-born residents. METHODS Using national incidence data for cancers of the stomach, liver, and cervix diagnosed during 2005 to 2014, incidence rates were compared for selected migrant groups with the Australian-born population using incidence rate ratios (IRR), from a negative binomial regression model. RESULTS Wide variations in incidence between countries/regions of birth were observed for all three cancers (P < 0.0001). The patterns were similar for cancers of the stomach and liver, in that migrants from countries/regions with higher incidence rates maintained an increased risk in Australia, with the highest being among South American migrants (IRR = 2.35) for stomach cancer and among Vietnamese migrants (5.44) for liver cancer. In contrast, incidence rates of cervical cancer were lower for many migrant groups, with women from Southern Asia (0.39) and North Africa (0.42) having the lowest rates. The rate of cervical cancer was higher in migrants from New Zealand, Philippines, and Polynesia. CONCLUSIONS Several Australian migrant groups were found to experience a disproportionate burden of infection-related cancers; further studies of associated risk factors may inform the design of effective interventions to mediate these disparities. IMPACT By identifying these migrant groups, it is hoped that these results will motivate and inform prevention or early detection activities for these migrant groups.

Drug use disorder and risk of incident and fatal prostate cancer among Swedish men: a nationwide epidemiological study. Cancer Causes Control 2021; 33:213-222.

Abstract
Purpose Prostate cancer is the second most common cancer in men and a leading cause of cancer mortality worldwide. Men with drug use disorders (DUD) may potentially be at high risk for prostate cancer mortality because of delayed diagnosis and/or undertreatment. In this study, we aimed to investigate prostate cancer incidence, mortality, and stage at time of diagnosis among men with DUD compared to the general male population in Sweden. Methods We performed a follow-up study based on Swedish national register data for the period January 1997–December 2016. The study was based on 1,361,532 men aged 50–75 years at inclusion, of whom 9,259 were registered with DUD. Cox regression analysis was used to compute adjusted hazard ratios (HRs) for incident and fatal prostate cancer, and cancer stage at time of diagnosis, associated with DUD. Results DUD was associated with a slightly increased risk of incident prostate cancer (HR: 1.07, 95% confidence interval [CI] 1.00–1.14, p = 0.048) and substantially higher risk of fatal prostate cancer (HR: 1.59, 95% CI 1.40–1.82, p < 0.001), adjusted for age, socioeconomic factors, and comorbidities related to tobacco smoking and alcohol use disorder. No association was found between DUD and prostate cancer stage at diagnosis. Conclusions Men with DUD have an increased risk of fatal prostate cancer, possibly related to undertreatment in this patient population. Our findings should raise attention among medical staff and decision-makers towards a disadvantaged group of men in need of easily accessible prostate cancer evaluation and treatment.

Abstract
PURPOSE Contention surrounds how best to screen patients for latent and undiagnosed infection prior to cancer treatment. Early treatment and prophylaxis against reactivation may improve infection-associated morbidity. This study sought to examine rates of screening and prevalence of latent infection in overseas-born patients receiving cancer therapies. METHODS A single-centre retrospective audit of 952 overseas-born patients receiving chemotherapy, targeted agents and immunotherapy between January 1 and December 31 2019 was undertaken at Peter MacCallum Cancer Centre. Pre-treatment screening for hepatitis B (HBV), hepatitis C (HCV), human immunodeficiency virus (HIV), latent tuberculosis (LTBI), toxoplasmosis and strongyloidiasis was audited. RESULTS Approximately half of our overseas-born patients were screened for HBV (58.9%) and HCV (50.7%). Fewer patients were screened for HIV (30.5%), LTBI (18.3%), strongyloidiasis (8.6%) or toxoplasmosis (8.1%). Although 59.7% of our patients were born in countries with high epidemiological risk for latent infection, according to World Health Organization data, 35% were not screened for any infection prior to commencement of therapy. CONCLUSION The prevalence of latent infections amongst overseas-born patients with cancer, and complexities associated with risk-based screening, likely supports universal latent infection screening amongst this higher-risk cohort.

Abstract
BACKGROUND NSW has a multicultural population with increasing migration from South East Asia, the Western Pacific and Eastern Mediterranean. OBJECTIVE To compare cancer stage, treatment (first 12 months) and survival for 12 country of birth (COB) categories recorded on the population-based NSW Cancer Registry. DESIGN Historic cohort study of invasive breast cancers diagnosed in 2003-2016. PATIENTS Data for 48,909 women (18+ ages) analysed using linked cancer registry, hospital inpatient and Medicare and pharmaceutical benefits claims data. MEASUREMENT Comparisons by COB using multivariate logistic regression and proportional hazards regression with follow-up of vital status to April 30th, 2020. RESULTS Compared with the Australia-born, women born in China, the Philippines, Vietnam and Lebanon were younger at diagnosis, whereas those from the United Kingdom, Germany, Italy and Greece were older. Women born in China, the Philippines, Vietnam, Greece and Italy lived in less advantaged areas. Adjusted analyses indicated that: (1) stage at diagnosis was less localised for women born in Germany, Greece, Italy and Lebanon; (2) a lower proportion reported comorbidity for those born in China, the Philippines and Vietnam; (3) surgery type varied, with mastectomy more likely for women born in China, the Philippines and Vietnam, and less likely for women born in Italy, Greece and Lebanon; (4) radiotherapy was more likely where breast conserving surgery was more common (Greece, Italy, and Lebanon) and the United Kingdom; and (5) systemic drug therapy was less common for women born in China and Germany. Five-year survival in NSW was high by international standards and increasing. Adjusted analyses indicate that, compared with the Australian born, survival from death from cancer at 5 years from diagnosis was higher for women born in China, the Philippines, Vietnam, Italy, the United Kingdom and Greece. CONCLUSIONS There is diversity by COB of stage, treatment and survival. Reasons for survival differences may include cultural factors and healthier migrant populations with lower comorbidity, and potentially, less complete death recording in Australia if some women return to their birth countries for treatment and end-of-life care. More research is needed to explore the cultural and clinical factors that health services need to accommodate.

Abstract
BACKGROUND Several social determinants of health have been examined in relation to colorectal cancer incidence, stage at diagnosis, and survival including income, education, neighborhood disadvantage, immigration status, social support, and social network. Colorectal cancer incidence rates are positively associated with income and other measures of socioeconomic status. In contrast, low socioeconomic status tends to be associated with poorer survival. METHODS The present review is based upon bibliographic searches in PubMed and CINAHL and relevant search terms. Articles published in English from 1970 through April 1, 2019 were identified using the following MeSH search terms and Boolean algebra commands: colorectal cancer AND (incidence OR stage OR mortality) AND (social determinants OR neighborhood disadvantage OR racial discrimination OR immigration OR social support). RESULTS This review indicates that poverty, lack of education, immigration status, lack of social support, and social isolation play important roles in colorectal cancer stage at diagnosis and survival. CONCLUSIONS To address social determinants of colorectal cancer, effective interventions are needed that account for the social contexts in which patients live.

Abstract
Social determinants of health that have been examined in relation to prostate cancer incidence, stage at diagnosis, and survival include socioeconomic status (income, education), neighborhood disadvantage, immigration status, social support, and social network. Other social determinants of health include geographic factors such as neighborhood access to health services. Socioeconomic factors influence risk of prostate cancer. Prostate cancer incidence rates tend to be positively associated with socioeconomic status. On the other hand, low socioeconomic status is associated with increased risk of poorer survival. There are well-documented disparities in prostate cancer survival by socioeconomic status, race, education, and census tract-level poverty. The results of this review indicate that social determinants such as poverty, lack of education, immigration status, lack of social support, and social isolation play an important role in prostate cancer stage at diagnosis and survival. To address these social determinants and eliminate cancer disparities, effective interventions that account for the social and environmental contexts in which patients with cancer live and are treated are needed.

Abstract
PURPOSE The ratio of cancer mortality and cancer incidence rates in a population has conventionally been used as an indicator of the completeness of cancer registration. More recently, the complement of the mortality-to-incidence ratio (1-M/I) has increasingly been presented as a surrogate for cancer survival. We discuss why this is mistaken in principle and misleading in practice. METHODS We provide an empirical assessment of the extent to which trends in the 1-M/I ratio reflect trends in cancer survival. We used national cancer incidence, mortality and survival data in England to compare trends in both the 1-M/I ratio and net survival at 1, 5, and 10 years for 19 cancers in men and 20 cancers in women over the 29-year period from 1981 to 2009. RESULTS The absolute difference between the 1-M/I ratio and 5-year net survival for 2009 was less than 5% for only 12 of the 39 cancer/sex combinations examined. For an additional 12, the 1-M/I ratio differed from 5-year net survival by at least 15%. The comparison is also unstable over time; thus, even when differences were small for 2009, the difference between 5-year net survival and the 1-M/I ratio had changed dramatically for most cancers between 1981 and 2009. CONCLUSION The 1-M/I ratio lacks any theoretical basis as a proxy for cancer survival. It is not a valid proxy for cancer survival in practice, either, whether at 5 years or at any other time interval since diagnosis. It has none of the useful properties of a population-based survival estimate. It should not be used as a surrogate for cancer survival.
