High-quality information about cancer treatment-related cardiovascular disease can prepare patients and reduce anxiety. The aim of this project was to systematically identify Australian online information resources about cardiovascular health after cancer and assess the readability, understandability, actionability, and cultural relevance for Aboriginal and Torres Strait Islander patients. METHODS We conducted systematic Google and website searches to identify potentially relevant resources. Eligibility was assessed using predefined criteria. For each eligible resource, we summarized the content and assessed readability, understandability, actionability, and cultural relevance for Aboriginal and Torres Strait Islander people. RESULTS Seventeen online resources addressing cardiovascular health after cancer were identified: three focused s...

This exploratory study describes QoL among Aboriginal and non-Aboriginal cancer patients in the NT, in the first year of diagnosis. Participants were recruited from the only cancer care centre in the NT and completed the Assessment of Quality-of-Life questionnaire (AQoL-4D). The results were descriptively analysed. The participants’ (n = 63; mean age 58.8 years) mean AQoL utility score was 0.72 (SD 0.26); patients scored lowest in the relationships and mental health dimensions of the questionnaire (mean 0.89, SD 0.19, and 0.89, SD 0.17, respectively). Participants living in remote and very remote areas (46%) reported higher QoL scores, compared with participants in the outer regional capital city of the NT in the overall (mean 0.76, SD 0.22 and 0.78, SD 0.20 vs. 0.67, SD 0.29, respectively), and mental health dimensions ...

Aboriginal and Torres Strait Islander peoples experience higher cancer mortality than other Australians. To date, very little is known about the support needs of carers of Aboriginal and Torres Strait Islander adults with cancer. This article explored these needs through a qualitative study. Twenty-two semi-structured qualitative interviews and one focus group were conducted with carers of Aboriginal and Torres Strait Islander adults with cancer (n = 12) and Aboriginal and Torres Strait Islander cancer survivors (n = 15) from Queensland, Australia. Half of the carers interviewed were Aboriginal or Torres Strait Islander Australians. Interviews were transcribed, coded and thematically analysed following an interpretive phenomenological approach. Thematic analysis of carer and survivor interviews revealed four key themes relating to carers’ needs: managing multiple responsibilities; maintaining the carer’s own...

Methods: Aboriginal and Torres Strait Islander adults completed an online survey at Time 1 (October-November 2019; before the initial Australian COVID-19 outbreak) and Time 2 (August-September 2020; after the first Australian lockdown). We assessed wellbeing using a visual analogue scale (VAS) and HRQoL using the Assessment of Quality of Life (AQoL-4D) instrument. Participants who completed both surveys (n=42) were included to quantify change in outcomes over time and by comorbidity and demographic factors. Results: Mean reduction in wellbeing over time was 6.4 points (95%CI-14.2 to 1.4) and was associated with age (18-54yo), financial instability and mental health comorbidity. Mean reduction in HRQoL over time was 0.06 (95%CI-0.12 to 0.01) and was associated with financial instability, high physical comorbidity level and mental health comorbidity. Conclusions: Aboriginal and Torres Strait Islanders aged 18-54yo, who were financially unstable or had elevated comorbidity during COVID lockdowns experienced greater reductions in wellbeing and HRQoL. Implications for public health: As the COVID-19 pandemic continues in Australia, both urgent and forward planning is needed, especially for the priority groups identified.

However, limited research has explored the costs to the Australian healthcare system associated with breast cancer. We aimed to describe the cost to hospital funders for hospital episodes and emergency department (ED) presentations for Queensland women with breast cancer, and whether costs varied by demographic characteristics. Methods We used a linked administrative dataset, CancerCostMod, limited to all breast cancer diagnoses aged 18 years or over in Queensland between July 2011 and June 2015 (n = 13,285). Each record was linked to Queensland Health Admitted Patient Data Collection and Emergency Department Information Systems records between July 2011 and June 2018. The cost of hospital episodes and ED presentations were determined, with mean costs per patient modelled using generalised linear models with a gamma distribution and log link function. Results The total cost to the Queensland healthcare system from hospital episodes for female breast cancer was AUD$309 million and AUD$12.6 million for ED presentations during the first 3 years following diagnosis. High levels of costs and service use were identified in the first 6 months following diagnosis. Some significant differences in cost of hospital and ED episodes were identified based on demographic characteristics, with Indigenous women and those from lower socioeconomic backgrounds having higher costs. Conclusion Hospitalisation costs for breast cancer in Queensland exert a high burden on the healthcare system. Costs are higher for women during the first 6 months from diagnosis and for Indigenous women, as well as those with underlying comorbidities and lower socioeconomic position.

This is in part due to the NT's unique geographic, socioeconomic and demographic profile. This paper describes the use of health services by cancer patients in the NT. Methods Adult cancer patients attending appointments at a cancer centre in Darwin, NT and who were diagnosed within the past five years were invited to participate in face-to-face interviews about their use of allied and community health services. A descriptive analysis of health services utilization was conducted. Results Of the 76 participants interviewed, 63% identified as non-Indigenous, 53% female and 45% lived in very remote areas. Mean age at interview was 58.7 years (SD 13.2). Overall, 82% of participants utilized at least one health service since their cancer diagnosis. All Indigenous participants used at least one service, while 28% of non-Indigenous participants did not use any health service. The services most frequently used by participants were community services (42%) and information sources (40%). Conclusion The findings from this study suggest there is variation in the type of community and allied health services used by NT cancer patients across clinical and demographic groups (including Indigenous status). Further qualitative enquiry is needed to better understand this variation, which may reflect differences in service preference, accessibility, health literacy of patients or patient engagement. Such knowledge may inform service delivery improvements to better support cancer patients through their cancer care pathway.

Indigenous peoples’ concepts and understanding of health and wellbeing are holistic; however, due to their diverse social, political, cultural, environmental and economic contexts within and across countries, wellbeing is not experienced uniformly across all Indigenous populations. We aim to identify aspects of wellbeing important to the Indigenous people in Canada, Aotearoa and the United States. We searched CINAHL, Embase, PsycINFO and PubMed databases for papers that included key Indigenous and wellbeing search terms from database inception to April 2020. Papers that included a focus on Indigenous adults residing in Canada, Aotearoa and the United States, and that included empirical qualitative data that described at least one aspect of well...

We summarize recent publications concerning cancer disparities affecting Australian Aboriginal and Torres Strait Islander Peoples and Aotearoa New Zealand Māori Peoples. Recent findings Cancer-free survival and overall survival statistics testify to the urgent need to ‘close the gap’. For Indigenous peoples in Australia and New Zealand, disparity persists along the cancer care pathway, from increased risk factors to lower screening access, health resource utilization and survivorship care. Recent publications highlight multimorbidity as contributing to poor cancer outcomes in Indigenous populations. The implementation of tailored Optimal Care Pathways is described, as is the validation of tailored tools capturing the perspectives of Indigenous persons. Finally, the importance of Indigenous-led research is emphasized. Summary Cancer-specific outcomes in Indigenous people of Australia and New Zealand remain poor with many widening disparities compared to non-indigenous populations. A growing body of epidemiological, health service and clinical research is documenting both the problems and potential solutions. Further work is needed in both broad health policies and the workforce, in building cultural competence to optimize individual care encounters.
BackgroundPoorer cancer outcomes of Indigenous Australians in Australia’s Northern Territory (NT)... more BackgroundPoorer cancer outcomes of Indigenous Australians in Australia’s Northern Territory (NT) compared with their non-Indigenous counterparts are partially due to diminished access to cancer treatment services (CTS). Accessibility of health care is a multidimensional construct, including physical, logistical, psychosocial and cultural dimensions. While previous research has identified specific areas of reduced access to CTS for Indigenous Australians, the higher burden of cancer borne by Indigenous Australians warrants a more comprehensive understanding of access to CTS in the NT. The purpose of this study was to explore and map the accessibility of CTS for Indigenous Australians in the NT and to identify key access barriers.MethodsThis predominantly qualitative study, complemented by a descriptive quantitative component, explored and mapped the accessibility of one CTS (CTS-NT) that services a large number of Indigenous Australians in the NT. Patient perspectives were obtained ...

Despite the impact of cancer on life expectancy, little is known about the burden of cancer for Indigenous people primarily because of the paucity of data. We investigated the collection and reporting of Indigenous status information among a global sample of population-based cancer registries (PBCRs). PARTICIPANTS AND METHODS An online survey was e-mailed to eligible registries using set inclusion criteria. Respondents were asked questions on the collection, reporting, and quality assessment of Indigenous status in their registers. RESULTS Eighty-three PBCRs from 25 countries were included. Of these, 66% reported that their registry collected Indigenous status data, although the quality of this variable had been assessed in less than half in terms of completeness (38%) and accuracy (47%).

In this study, we assessed the documented delivery of cervical screening for women attending Indigenous Primary Health Care (PHC) centres across Australia and identified service-level factors associated with between-centre variation in screening coverage. We analysed 3801 clinical audit records for PHC clients aged 20–64 years from 135 Indigenous PHC centres participating in the Audit for Best Practice in Chronic Disease (ABCD) continuous quality improvement (CQI) program across five Australian states/territories during 2005 to 2014. Multilevel logistic regression models were used to identify service-level factors associated with screening, while accounting for differences in client-level factors. There was substantial variation in the proportion of clients who had a documented cervical screen in the previous two years across the participating PH...

The National Indigenous Cervical Screening Project used probabilistic record linkage to combine population-based administrative databases and identify Indigenous women on Pap Smear Registers. This study aimed to quantify the spatial variation by local government areas (LGAs) for Indigenous and non-Indigenous women in Queensland in cervical screening participation rates and related outcomes. Empirical Bayes local geostatistical smoothing was performed to reduce the likelihood of spurious variation between small areas. The cohort included 1,091,260 women (2 per cent Indigenous) aged 20 to 69 with 2,393,708 Pap smears between 2006 and 2011. Indigenous women had smoothed LGA-specific 5-year participation rates (interquartile range (IQR) 38.9-53.3 per 100 eligible women) consistently lower than non-Indigenous women (IQR 80.7-85.3). The non-overlapping confidence intervals of these rates suggest that the Indigenous differential was significant. Compared with Indigenous women, non-Indigenous women had consistently lower and more stable prevalence rates of histologically confirmed high grade abnormalities (IQR 8.0-10.1 versus 15.0-21.3 per 1,000 screened women). Although the LGA-specific rates also suggest that a higher proportion of non-Indigenous women were followed-up within two months of an abnormal screening result, the wide confidence intervals for these estimates limit our ability to draw definitive conclusions about spatial patterns for this outcome. These findings highlight the importance of continued monitoring and ongoing efforts to identify drivers of these patterns and develop effective

We investigated differences by Aboriginal status in abnormality rates predicted by cervical cytology and confirmed by histological diagnoses among screened women. Methods Using record linkage between cervical screening registry and public hospital records in South Australia, we obtained Aboriginal status of women aged 20–69 for 1993–2016 (this was not recorded by the registry). Differences in cytological abnormalities were investigated by Aboriginal status, using relative risk ratios from mixed effect multinomial logistic regression modelling. Odds ratios were calculated for histological high grade results for Aboriginal compared with non-Aboriginal women. Results Of 1,676,141 linkable cytology tests, 5.8% were abnormal. Abnormal r...

Data for cervical cancers diagnosed in 2003-2012 were extracted from six Australian state-based cancer registries and linked to hospital inpatient records to identify comorbidity diagnoses. Five-year cause-specific and all-cause survival probabilities were estimated using the Kaplan-Meier method. Flexible parametric models were used to estimate excess cause-specific mortality by Charlson comorbidity index score (0,1,2+), for Indigenous women compared to non-Indigenous women. Of 4,467 women, Indigenous women (4.4%) compared to non-Indigenous women had more comorbidity at diagnosis (score ≥1: 24.2% vs. 10.0%) and lower five-year cause-specific survival (60.2% vs. 76.6%). Comorbidity was associated with increased cervical cancer mortality for non-In...

Participation in cervical screening is significantly lower and the prevalence of cervical abnormalities significantly higher among Indigenous than non-Indigenous women in Queensland. The new Indigenous women are less likely to undergo clinical investigation within the recommended 2 months of a high grade abnormal Pap smear result, but by 6 months the follow-up rate was similar for Indigenous and non-Indigenous women. The implications Improving timeliness of follow-up and increasing participation in cervical cancer prevention is important for reducing the higher burden of cervical cancer among Indigenous women.

This crosssectional study investigated the association between comorbidity and SCN among newly diagnosed Indigenous cancer patients in Queensland. Comorbidity was ascertained from medical chart review using the Charlson Comorbidity Index (CCI) and SCN were measured using the Supportive Care Needs Assessment Tool for Indigenous Peoples (SCNAT-IP). Of 183 participants, 76 (42%) had no comorbidity (CCI = 0), 60 (33%) had had a CCI score of 1 and 47 (26%) had a CCI of two or more, with the most common condition being diabetes (30%). The most common moderate-high unmet need items varied between comorbidity groups, although all patients most frequently reported moderate-high unmet need in the Physical and Psychological and the Practical and Cultural needs domains. Patients with the greatest comorbidity (CCI ≥ 2) had significantly more reduced odds of practical and cultural needs than patients without comorbidity (OR 0.28, 95% CI 0.11-0.75). This appeared to be partially explained by time since diagnosis, age, whether they were receiving current treatment and residential remoteness. Patients' experience of chronic disease, hospitals and the healthcare system may better prepare them for the practical and cultural aspects of their cancer journey.

However, limited research has explored the costs to the Australian healthcare system associated with breast cancer. We aimed to describe the cost to hospital funders for hospital episodes and emergency department (ED) presentations for Queensland women with breast cancer, and whether costs varied by demographic characteristics. Methods We used a linked administrative dataset, CancerCostMod, limited to all breast cancer diagnoses aged 18 years or over in Queensland between July 2011 and June 2015 (n = 13,285). Each record was linked to Queensland Health Admitted Patient Data Collection and Emergency Department Information Systems records between July 2011 and June 2018. The cost of hospital episodes and ED presentations were determined, with mean costs per patient modelled using generalised linear models with a gamma distribution and log link function. Results The total cost to the Queensland healthcare system from hospital episodes for female breast cancer was AUD$309 million and AUD$12.6 million for ED presentations during the first 3 years following diagnosis. High levels of costs and service use were identified in the first 6 months following diagnosis. Some significant differences in cost of hospital and ED episodes were identified based on demographic characteristics, with Indigenous women and those from lower socioeconomic backgrounds having higher costs. Conclusion Hospitalisation costs for breast cancer in Queensland exert a high burden on the healthcare system. Costs are higher for women during the first 6 months from diagnosis and for Indigenous women, as well as those with underlying comorbidities and lower socioeconomic position.

Methods Using record linkage between cervical screening registry and public hospital records in South Australia, we obtained Aboriginal status of women aged 20–69 for 1993–2016 (this was not recorded by the registry). Differences in cytological abnormalities were investigated by Aboriginal status, using relative risk ratios from mixed effect multinomial logistic regression modelling. Odds ratios were calculated for histological high grade results for Aboriginal compared with non-Aboriginal women. Results Of 1,676,141 linkable cytology tests, 5.8% were abnormal. Abnormal r...

Data for cervical cancers diagnosed in 2003-2012 were extracted from six Australian state-based cancer registries and linked to hospital inpatient records to identify comorbidity diagnoses. Five-year cause-specific and all-cause survival probabilities were estimated using the Kaplan-Meier method. Flexible parametric models were used to estimate excess cause-specific mortality by Charlson comorbidity index score (0,1,2+), for Indigenous women compared to non-Indigenous women. Of 4,467 women, Indigenous women (4.4%) compared to non-Indigenous women had more comorbidity at diagnosis (score ≥1: 24.2% vs. 10.0%) and lower five-year cause-specific survival (60.2% vs. 76.6%). Comorbidity was associated with increased cervical cancer mortality for non-In...

Participation in cervical screening is significantly lower and the prevalence of cervical abnormalities significantly higher among Indigenous than non-Indigenous women in Queensland. The new Indigenous women are less likely to undergo clinical investigation within the recommended 2 months of a high grade abnormal Pap smear result, but by 6 months the follow-up rate was similar for Indigenous and non-Indigenous women. The implications Improving timeliness of follow-up and increasing participation in cervical cancer prevention is important for reducing the higher burden of cervical cancer among Indigenous women.
Supportive care needs among Indigenous cancer patients in Queensland, Australia: less comorbidity... more Supportive care needs among Indigenous cancer patients in Queensland, Australia: less comorbidity is associated with greater practical and cultural unmet need Little is known about the supportive care needs (SCN) of Australian Indigenous cancer patients. This crosssectional study investigated the association between comorbidity and SCN among newly diagnosed Indigenous cancer patients in Queensland. Comorbidity was ascertained from medical chart review using the Charlson Comorbidity Index (CCI) and SCN were measured using the Supportive Care Needs Assessment Tool for Indigenous Peoples (SCNAT-IP). Of 183 participants, 76 (42%) had no comorbidity (CCI = 0), 60 (33%) had had a CCI score of 1 and 47 (26%) had a CCI of two or more, with the most common condition being diabetes (30%). The most common moderate-high unmet need items varied between comorbidity groups, although all patients most frequently reported moderate-high unmet need in the Physical and Psychological and the Practical and Cultural needs domains. Patients with the greatest comorbidity (CCI ≥ 2) had significantly more reduced odds of practical and cultural needs than patients without comorbidity (OR 0.28, 95% CI 0.11-0.75). This appeared to be partially explained by time since diagnosis, age, whether they were receiving current treatment and residential remoteness. Patients' experience of chronic disease, hospitals and the healthcare system may better prepare them for the practical and cultural aspects of their cancer journey.
