Health literacy in relation to cancer: addressing the silence about and absence of cancer discussion among Aboriginal people, communities and health services

Gynaecological cancer resources for Aboriginal and Torres Strait Islander women: A resource audit

ISSUE ADDRESSED

Aboriginal and Torres Strait Islander women experience considerable disparities in gynaecological cancer outcomes. Accessible and culturally appropriate health promotion resources about gynaecological cancers may support health literacy in this area. This study aimed to determine the understandability, actionability, readability, and cultural relevance of gynaecological cancer health literacy resources for Aboriginal and Torres Strait Islander consumers, families, and caregivers.

METHODS

We conducted a general Google search and targeted searches of Australian gynaecological cancer organisation websites in January and February 2022. Resources were assessed for understandability, actionability and cultural relevance to Aboriginal and Torres Strait Islander audiences.

RESULTS

We found 16 resources. The resources were generally understandable, actionable, readable, and culturally relevant, however, most resources were focused on cervical cancer prevention through vaccination and screening. Few resources focused other gynaecological cancer types or aspects of the cancer care continuum. While many resources contained elements that made them culturally relevant, areas for improvement were identified. These included: greater transparency relating to the Aboriginal and Torres Strait Islander leadership, governance, and involvement in the development of the resources as well as availability of different resource formats with an emphasis on visual aids.

CONCLUSIONS

This study highlighted a need for the development of resources relating to a wider range of gynaecological cancer types and different stages of the cancer care continuum for Aboriginal and Torres Strait Islander women. SO WHAT?: The development of a broader range of culturally appropriate gynaecological cancer health literacy resources, ideally developed through co-design with Aboriginal and Torres Strait Islander peoples, may contribute to addressing the disparities in gynaecological cancer outcomes for Aboriginal and Torres Strait Islander women.

'Even though you hate everything that's going on, you know they are safer at home': The role of Aboriginal and Torres Strait Islander families in methamphetamine use harm reduction and their own support needs

Introduction

First Nations people who use methamphetamine are overrepresented in regional and remote Australia and more likely to turn to family for support. This can place strain on families. The support needs of family members of individuals using methamphetamine are poorly understood.

Methods

We conducted 19 focus groups and seven interviews with mostly First Nations community, family members and service providers. In total, 147 participants across six sites participated as part of a larger study investigating First Nations perspectives of how to address methamphetamine use and associated harms. We applied a social and emotional wellbeing framework to examine support needs and role of family in mitigating methamphetamine harms.

Results

Findings highlighted the importance of families in providing support to people using methamphetamine and in reducing associated harms, often without external support. The support provided encompassed practical, social, emotional, financial, access to services and maintaining cultural connection. Providing support took a toll on family and negatively impacted their own social and emotional wellbeing.

Discussion and Conclusions

First Nations families play an important and under‐recognised role in reducing methamphetamine‐related harms and greater efforts are required to support them. Professional resources are needed to deal with impacts of methamphetamine on families; these should be pragmatic, accessible, targeted and culturally appropriate. Support for families and communities should be developed using the social and emotional wellbeing framework that recognises wellbeing and healing as intrinsically connected to holistic health, kinship, community, culture and ancestry, and socioeconomic and historical influences on peoples' lives.

The role of health literacy in cancer care: A mixed studies systematic review

BACKGROUND

Patients diagnosed with cancer face many challenges and need a good understanding of their diagnosis and proposed treatments to make informed decisions about their care. Health literacy plays an important role in this and low health literacy has been associated with poorer outcomes. The aims of this review are to identify which outcomes relate to health literacy in patients with cancer, and to combine this through a mixed studies approach with the patient experience as described through qualitative studies.

METHODS

Four electronic databases were searched in January 2021 to identify records relating to health literacy and patients with cancer. Records were independently screened then assessed for inclusion by two reviewers according to the following criteria: patients aged ≥18 years with cancer, English language publication AND health literacy measured with validated tool and measured outcome associated with health literacy OR qualitative study exploring the role of health literacy as patients make decisions about health. Quality was independently assessed by two reviewers. A narrative synthesis was performed, and findings integrated through concept mapping. This systematic review was registered with PROSPERO, entry CRD42020166454.

RESULTS

4441 records were retrieved. Following de-duplication, 2496 titles and abstracts were screened and full texts of 405 papers were reviewed for eligibility. 66 papers relating to 60 studies met the eligibility criteria. Lower health literacy was associated with greater difficulties understanding and processing cancer related information, poorer quality of life and poorer experience of care. Personal and situational influences contributed to how participants processed information and reached decisions about their care.

CONCLUSION

This review highlights the important role of health literacy for patients with cancer. Outcomes are poorer for those who experience difficulties with health literacy. Further efforts should be made to facilitate understanding, develop health literacy and support patients to become more involved in their care.

Chronic disease health literacy in First Nations people: A mixed methods study

AIM

To explore chronic disease education, self-management and health literacy abilities from First Nations Australian adults with chronic disease through the integration of qualitative and quantitative findings.

BACKGROUND

Chronic disease management requires good health literacy abilities to manage long-term health needs. First Nations people have a higher burden of chronic disease although little is known regarding chronic disease health literacy of First Nations people.

DESIGN

A concurrent embedded mixed methods study reported using the Consolidated Criteria for Reporting Qualitative Research guidelines.

METHODS

Data were collected from First Nations people with one or more chronic diseases living in remote Australia between February-November 2017. Quantitative data (n = 200) were collected using the Health Literacy Questionnaire along with demographic and health data. Qualitative data (n = 20) were collected via face-to-face interviews to examine chronic disease education and self-management experiences. Data were analysed separately then integrated to develop meta-inferences.

RESULTS

Poor communication from healthcare providers coupled with low health literacy abilities is a major barrier to both active and successful management of chronic disease. Communicating in medical jargon resulted in individuals being placed in a power differential causing lack of trust and relationship breakdowns with healthcare providers affecting active chronic disease self-management. The perception of inevitability and ambivalence towards chronic disease and the notion of futility towards self-management were concurred with the low level of active engagement in health care.

CONCLUSIONS

Yarning is an important strategy used by First Nations people for communication. For nurses, understanding and developing skills in yarning will facilitate cultural safety, communication and understanding about chronic disease self-management in contexts where health literacy abilities are challenged.

RELEVANCE TO CLINICAL PRACTICE

Using yarning, and plain language visual aids, and teach-back will readdress the power differential experienced by First Nations people and may also improve understanding of chronic disease self-management.

Quality of life and associated factors among adults living with cancer and their family caregivers

This study examined the association of needs, health literacy, and quality of life among adult Nigerians with cancer and family caregivers. A descriptive study was conducted involving 240 adults with cancer and family caregivers attending a tertiary hospital. More than two-thirds of participants reported moderate or high needs. Information (90.8%) and spiritual support (85%) were the domains of highest need among adults with cancer. Family/social support (85%) and spiritual support (81.7%) ranked the highest among family caregivers. A negative correlation was found between needs and quality of life. Stepwise regression analysis showed that needs and literacy explained 36% of the variance in adults with cancer's quality of life and 28% of the variance in family caregivers' quality of life. Spiritual need accounted l for 9.5% and 9.1% of variation for adults with cancer and family caregivers, respectively. Findings suggest that interventions with a focus on social/family and spiritual needs may improve wellbeing of adults with cancer and caregivers in Nigeria. This research are generalizable to other low-income countries where family values and spirituality are often a strong feature of daily life.

Exploring the barriers preventing Indigenous Australians from accessing cancer genetic counseling

In Australia, individuals of Aboriginal and Torres Strait Islander descent (Indigenous Australians) have poorer health outcomes than the general population, including higher incidence of cancer and reduced life expectancy up to 14 years compared to non-Indigenous Australians. Although differences in engagement with healthcare and beliefs about disease/cancer exist between Indigenous communities, a number of common barriers have been identified hindering attendance at mainstream health services. To inform exploration of barriers that may impact access to a cancer genetic counseling service, consultations with Aboriginal stakeholders were undertaken. Ethical principles for studies that engage Indigenous communities were followed throughout the research endeavor. Using a stakeholder-endorsed focus group approach, the views of an Aboriginal Elders group (n = 9) were sought with additional semi-structured interviews with social science and genetics researchers working with Indigenous communities in Australia (n = 7). Thematic analysis of the results identified three themes: explanatory models of illness, barriers to keeping well and attending services, and recommendations for improvements to access/attendance. Barriers common to accessing both mainstream health services and clinical genetic services were identified, including attributions of illness and cancer. Specific genetic counseling barriers included the cultural inclusivity and accessibility of services, and a lack of awareness of genetic counseling both in the community and by clinicians unfamiliar with genetics. Recommendations included developing flexible service delivery models and culturally appropriate resources for Indigenous patients. These findings may inform future studies to improve Indigenous health outcomes and promote a more accessible, culturally appropriate approach to provision of cancer genetics services for Australia's First Peoples.

Understanding Aboriginal Peoples' Cultural and Family Connections Can Help Inform the Development of Culturally Appropriate Cancer Survivorship Models of Care

PURPOSE

To explore the cancer diagnosis, treatment, and survivorship experiences of Aboriginal people in the Gippsland region, Victoria, Australia, and identify factors critical to the development of a culturally appropriate cancer survivorship model of care.

PATIENTS AND METHODS

Yarning circles were used to capture the stories of 15 people diagnosed with cancer and/or those of family members. Yarning circles were conducted in two locations in the Gippsland region. Sessions were facilitated by an Aboriginal Elder, audio recorded, and transcribed verbatim. Thematic analysis of the data were triangulated among three researchers and incorporated researcher reflexivity.

RESULTS

Cultural connections and family were critical supports on the cancer journey. Putting the needs of the family first and caring for sick family members were more important than an individual's own health. There was "no time to grieve" for one's own cancer diagnosis and look after oneself. Cancer was a private experience; however, the constancy of deaths highlighted the importance of raising family awareness. Health professionals did not always understand the importance of people's cultural and family supports in their treatment and recovery. There were negatives attitudes in hospitals when family come to visit, seeing family as too large and overstaying visiting times. Health professionals did not seek family assistance with communication of information to family members whose literacy level was low, nor did they include family in treatment decision-making. Access to services depended on family support with transport, finances, and family responsibilities, often resulting in lapses in treatment and follow-up services.

CONCLUSION

Understanding the importance of Aboriginal peoples' cultural and family connections can help to inform the development of culturally safe cancer survivorship models of care.

Patient Perspectives to Inform a Health Literacy Educational Program: A Systematic Review and Thematic Synthesis of Qualitative Studies

Patient-centred care is tailored to the needs of patients and is necessary for better health outcomes, especially for individuals with limited health literacy (LHL). However, its implementation remains challenging. The key to effectively address patient-centred care is to include perspectives of patients with LHL within the curricula of (future) healthcare providers (HCP). This systematic review aimed to explore and synthesize evidence on the needs, experiences and preferences of patients with LHL and to inform an existing educational framework. We searched three databases: PsychInfo, Medline and Cinahl, and extracted 798 articles. One-hundred and three articles met the inclusion criteria. After data extraction and thematic synthesis, key themes were identified. Patients with LHL and chronic diseases encounter multiple problems in the care process, which are often related to a lack of person-centeredness. Patient perspectives were categorized into four key themes: (1) Support system; (2) Patient self-management; (3) Capacities of HCPs; (4) Barriers in healthcare systems. "Cultural sensitivity" and "eHealth" were identified as recurring themes. A set of learning outcomes for (future) HCPs was developed based on our findings. The perspectives of patients with LHL provided valuable input for a comprehensive and person-centred educational framework that can enhance the relevance and quality of education for (future) HCPs, and contribute to better person-centred care for patients with LHL.

Does gynaecological cancer care meet the needs of Indigenous Australian women? Qualitative interviews with patients and care providers

Background

There is a disparity in the burden of gynaecological cancer for Indigenous women compared with non-Indigenous women in Australia. Understanding how Indigenous women currently experience gynaecological cancer care services and factors that impact on their engagement with care is critical. This study explored Indigenous Australian women’s experience of gynaecological cancer care at a major metropolitan hospital in Queensland.

Methods

Indigenous women receiving care at a major metropolitan Queensland hospital for investigation or diagnosis of gynaecological cancer were invited to participate in a larger longitudinal study exploring women’s experiences of gynaecological cancer care. This component was an in-depth, qualitative interview exploring the women’s experiences of hospital care at approximately three-month post initial referral. A peer-approach was used to interview women. Hospital-based care providers involved in the care of Indigenous gynaecological cancer patients were invited to be interviewed. Interviews were transcribed and thematically analysed using an interpretative phenomenological approach enabling a multi-layered, contextualised understanding of the patients' experience and their interaction with tertiary cancer services.

Results

Eight Indigenous patients and 18 care providers were interviewed. Analysis of all interviews revealed four broad issues affecting Indigenous patients’ early experiences of care: (1) navigating the system, impacted by timely diagnosis, access to support services and follow up; (2) communication and decision-making, patients’ decision-making, efficacy of doctor-patient communication, and patients’ knowledge about cancer; (3) coping with treatment demands, was impacted by emotional stress, access to services and support by hospital staff; and (4) feeling welcome and safe in the hospital, impacted by patients’ relationship with care providers and their access to culturally-safe services. The combination of factors impacting these women’s’ experience of gynaecological care commonly left these women at breaking point, often with limited access to information, resources or support.

Conclusions

Our findings revealed that experiences of cancer care for Indigenous women are overlain by challenges associated with late referral, misdiagnosis, miscommunication, lack of information, logistics in accessing treatment and services and system cultural insensitivities. Our findings offer insights that can inform cancer care provision to more effectively support Indigenous women accessing gynaecological cancer services.

Health literacy in Indigenous people with chronic disease living in remote Australia

Background

Health literacy is strongly associated with health outcomes and is important for health policy and service delivery. Low health literacy was reported in 59% of Australian adults, however, there is no national data on the health literacy of Aboriginal and Torres Strait Islander (ATSI) peoples. The ATSI population in Australia experience a notable gap in health outcomes compared with non-Indigenous Australians which is due, in part to a higher prevalence of chronic diseases. The health outcome gap is more pronounced in rural and remote locations. This study aims to establish the health literacy profile of ATSI adults with chronic disease living in remote North-West Queensland Australia, and to investigate associations between the Health Literacy Questionnaire (HLQ) domains and self-reported chronic disease and demographic characteristics.

Methods

Using a cross-sectional design, 200 ATSI adults with a diagnosis of chronic disease/s (cardiovascular disease, diabetes, respiratory disease and/or chronic kidney disease) were recruited from two sites with the assistance of Aboriginal Health Workers. Data were collected using the HLQ, a multidimensional 44 item instrument to assess nine domains of health literacy. Demographic and health data were also collected. Analysis of variance using backwards modelling was used to determine predictors of health literacy.

Results

Participants were mostly male (53.5%) and aged between 19 and 89 years. The most prevalent chronic disease was cardiovascular disease (74%) followed by diabetes (67.5%). More than half (62%) had two or more chronic diseases. There was at least one independent predicator for each of the nine health literacy domains. Age, number of chronic diseases, gender, and level of education were all highly significant predictors of health literacy.

Conclusion

Improved health literacy will enable individuals to take an active role in their health. Understanding the health literacy of ATSI adults is a crucial first step. Our findings can assist Australian healthcare organisations to review their health literacy responsiveness and examine ways to improve patients’ needs and health capabilities to better support people to engage in effective self-management for chronic diseases.

Understanding Indigenous Australians' experiences of cancer care: stakeholders' views on what to measure and how to measure it

Background

Disparities in cancer outcomes amongst Indigenous Australians reflect a pattern of reduced access to and engagement with health services. A growing emphasis on patient-centred care has increased efforts to measure patient experiences, but it is unclear whether existing approaches: a) assess the most critical aspects of care that shape the experiences of Indigenous people with cancer; and b) facilitate the engagement and participation of Indigenous people with the measurement of care experiences.

Methods

Two rounds of semi-structured interviews and focus groups were used to elicit stakeholders’ views on priorities for measuring the cancer care experiences of Indigenous cancer patients and on the acceptability of various methods for capturing such information. Participants included Indigenous people affected by cancer (n = 17), health professionals (n = 28) and individuals in both groups (n = 7). Recruitment occurred through a national web-based network and through four cancer services in urban and regional areas in three jurisdictions across Australia.

Results

Several aspects of cancer care were identified as critical in shaping Indigenous patients’ experiences. Key themes included: feeling safe in the system; importance of Indigenous staff; barriers to care; the role of family and friends; effective communication and education; and coordination of care and transition between services. Those participants affected by carers’ wellbeing and palliative care strongly advocated for the importance of these topics. Participants expressed support for a face-to-face interview with a trusted person as the most appropriate means of collecting cancer care experience information.

Conclusions

While existing experience measurement tools would partially capture some important aspects of care, other critical areas would likely be missed. Appropriate tools and approaches, developed by and with Indigenous people, are urgently needed to determine the extent to which health services are meeting the needs of Indigenous people with cancer, and to identify areas for action to improve these services.

An Exploration of Underrepresentation of Aboriginal Cancer Patients Attending a Regional Radiotherapy Service in Western Australia

Travel logistics impede Aboriginal patients' uptake of cancer treatments and is one reason for the poorer outcomes of Aboriginal people with cancer. This research examined benefits of a newly established rurally based radiotherapy unit in southwest Western Australia (WA), and included exploring the experience of Aboriginal patients and possible reasons for Aboriginal people's underrepresentation in treatment. Semi-structured in-depth interviews with 21 service providers involved in the treatment and care of people with cancer, and 3 Aboriginal patients with cancer who undertook radiotherapy at the Service were undertaken. Data were subject to thematic analysis involving immersion in the data for familiarization, inductive coding, investigator discussion and refining of emerging themes and triangulation of patient and provider interviews. Aboriginal cancer patients were positive about the treatment and support they had received, highlighting the often complex challenges faced by rural Aboriginal cancer patients in accessing and maintaining treatment. Service providers offered suggestions for small numbers presenting to the Service, including late presentation, potential perceptions of cultural insensitivity on the part of service providers, out-of-pocket costs and under-ascertainment of Aboriginal status. The Service has put in place practices and initiatives to support patient health and wellbeing, including making the facility more welcoming towards Aboriginal people and ensuring culturally appropriate care.

Perspectives of Aboriginal women on participation in mammographic screening: a step towards improving services

Background

Early detection of breast cancer using screening mammography provides an opportunity for treatment which can lead to significantly improved outcomes. Despite considerable efforts having been made, the rate at which Aboriginal and Torres Strait Islander (hereafter respectfully referred to as Aboriginal) women in Western Australia participate in BreastScreen WA’s screening mammogram program remains below that for the overall female population of Western Australia. This study aimed to examine perspectives on breast screening amongst Aboriginal women in Western Australia. We explored the factors which impact on participation in breast screening and sought to identify potential initiatives to address lower participation in screening.

Methods

Semi-structured interviews, focus group discussions and yarning sessions were conducted with a total of 65 research participants. They were all Aboriginal and comprised consumers and health professionals from locations across the state.

Results

Our findings show that research participants generally were willing to have a mammogram. Key reasons given were having a genetic predisposition to breast cancer and a perception of investing in health for the sake of the next generation, as well as personal well-being. Barriers identified included lack of education about or understanding of screening, inadequacies in cultural appropriateness in the screening program, cultural beliefs around cancer in general and breast cancer in particular, and competing health and life priorities. However, many enablers were identified which can serve as potential strategies to assuage fear and increase screening uptake. These included increased education delivered by respected Aboriginal women, culturally appropriate promotion and the provision of care and support from other women in the community.

Conclusion

The higher participation rates for Aboriginal women in Western Australia than are found for Aboriginal women nationally demonstrate the success of the strategies put in place by BreastScreen WA. These efforts must be supported and existing policies and practices enhanced to address the limitations in the existing program. Only by implementing and evaluating such initiatives and making breast screening programs more accessible to Aboriginal women can the current disparity between the screening participation rates of Aboriginal and non-Aboriginal women be reduced.

Managing Matajoosh: determinants of first Nations' cancer care decisions

BACKGROUND

Accessing cancer treatment requires First Nation peoples living in rural and remote communities to either commute to care, or to relocate to an urban centre for the length or part of the treatment. While Canadians living in rural and remote communities must often make difficult decisions following a cancer diagnosis, such decisions are further complicated by the unique policy and socio-historical contexts affecting many First Nation peoples in Canada. These contexts often intersect with negative healthcare experiences which can be related to jurisdictional confusion encountered when seeking care. Given the rising incidence of cancer within First Nation populations, there is a growing potential for negative health outcomes.

METHODS

The analysis presented in this paper focuses on the experience of First Nation peoples' access to cancer care in the province of Manitoba. We analyzed policy documents and government websites; interviewed individuals who have experienced relocation (N = 5), family members (N = 8), healthcare providers and administrators (N = 15).

RESULTS

Although the healthcare providers (social workers, physicians, nurses, patient navigators, and administrators) we interviewed wanted to assist patients and their families, the focus of care remained informed by patients' clinical reality, without recognition of the context which impacts and constrains access to cancer care services. Contrasting and converging narratives identify barriers to early diagnosis, poor coordination of care across jurisdictions and logistic complexities that result in fatigue and undermine adherence. Providers and decision-makers who were aware of this broader context were not empowered to address system's limitations.

CONCLUSIONS

We argue that a whole system's approach is required in order to address these limitations.

Routine screening of Indigenous cancer patients' unmet support needs: a qualitative study of patient and clinician attitudes

Background

Indigenous Australians have poorer cancer outcomes in terms of incidence mortality and survival compared with non-Indigenous Australians. The factors contributing to this disparity are complex. Identifying and addressing the psychosocial factors and support needs of Indigenous cancer patients may help reduce this disparity. The Supportive Care Needs Assessment Tool for Indigenous People (SCNAT-IP) is a validated 26-item questionnaire developed to assess their unmet supportive care needs. This qualitative study reports on patient and clinician attitudes towards feasibility and acceptability of SCNAT-IP in routine care.

Methods

Forty-four in-depth semi-structured interviews were conducted with 10 clinical staff and 34 Indigenous cancer patients with heterogeneous tumours. Participants were recruited from four geographically diverse Australian cancer clinics. Transcripts were imported into qualitative analysis software (NVivo 10 Software), coded and thematic analysis performed.

Results

Indigenous patients (mean age 54.4 years) found the SCNAT-IP beneficial and easy to understand and they felt valued and heard. Clinical staff reported multiple benefits of using the SCNAT-IP. They particularly appreciated its comprehensive and systematic nature as well as the associated opportunities for early intervention. Some staff described improvements in team communication, while both staff and patients reported that new referrals to support services were directly triggered by completion of the SCNAT-IP. There were also inter-cultural benefits, with a positive and bi-directional exchange of information and cultural knowledge reported when using the SCNAT-IP. Although staff identified some potential barriers to using the SCNAT-IP, including the time required, the response format and comprehension difficulties amongst some participants with low English fluency, these were outweighed by the benefits. Some areas for scaled improvement were also identified by staff.

Conclusions

Staff and patients found the SCNAT-IP to be an acceptable tool and supported universal screening for Indigenous cancer patients. The SCNAT-IP has the potential to help reduce the inequalities in cancer care experienced by Indigenous Australians by identifying and subsequently addressing their unmet support needs. Further research is needed to explore the validity of the SCNAT-IP for Indigenous people from other nations.

Lung cancer treatment and mortality for Aboriginal people in New South Wales, Australia: results from a population-based record linkage study and medical record audit

Background

The aim of this study was to compare surgical treatment received by Aboriginal and non-Aboriginal people with non-small cell lung cancer (NSCLC) in New South Wales (NSW), Australia and to examine whether patient and disease characteristics are associated with any disparities found. An additional objective was to describe the adjuvant treatments received by Aboriginal people diagnosed with NSCLC in NSW. Finally, we compared the risk of death from NSCLC for Aboriginal and non-Aboriginal people.

Methods

We used logistic regression and competing risks regression to analyse population-based cancer registry records for people diagnosed with NSCLC in NSW, 2001–2007, linked to hospital inpatient episodes and deaths. We also analysed treatment patterns from a medical record audit for 170 Aboriginal people diagnosed with NSCLC in NSW, 2000–2010.

Results

Of 20,154 people diagnosed with primary lung cancer, 341 (1.7 %) were Aboriginal. Larger proportions of Aboriginal people were younger, female, living outside major cities or in areas of greater socioeconomic disadvantage, smoking at the time of diagnosis and had comorbidities. Although Aboriginal people were, on average, younger at diagnosis with non-metastatic NSCLC than non-Aboriginal people, only 30.8 % of Aboriginal people received surgery, compared with 39.5 % of non-Aboriginal people. Further, Aboriginal people who were not receiving surgery, at the time of diagnosis, were more likely to be younger, live in major cities and have no comorbidities. The observed risk of death from NSCLC 5 years after diagnosis was higher for 266 Aboriginal people (83.3 % 95 % CI 77.5–87.7) than for 15,491 non-Aboriginal people (77.6 % 95 % CI 76.9–78.3) and the adjusted subhazard ratio was 1.32 (95 % CI 1.14–1.52). From the medical record audit, 29 % of Aboriginal people with NSCLC had potentially curative treatment, 45 % had palliative radiotherapy/chemotherapy and 26 % had no active treatment.

Conclusions

There are disparities in NSCLC surgical treatment and mortality for Aboriginal people compared with non-Aboriginal people in NSW. It is imperative that Aboriginal people are offered active lung cancer treatment, particularly those who are younger and without comorbidities and are therefore most likely to benefit, and are provided with assistance to access it if required.

Comparing colorectal cancer treatment and survival for Aboriginal and non-Aboriginal people in New South Wales

OBJECTIVES

Our aim was to compare surgical treatment rates and survival rates for Aboriginal and non-Aboriginal people in New South Wales with colorectal cancer, and to describe the medical treatment received by a sample of Aboriginal people with colorectal cancer.

DESIGN, SETTING AND PARTICIPANTS

All people diagnosed with colorectal cancer in NSW during 2001-2007 were identified and their cancer registry records linked to hospital admissions data and death records. A medical records audit of a sample of Aboriginal people diagnosed with colorectal cancer during 2000-2011 was also conducted.

MAIN OUTCOME MEASURES

Cause-specific survival, odds of surgical treatment, and the proportions of people receiving adjuvant treatments.

RESULTS

Of 29 777 eligible colorectal cancer cases, 278 (0.9%) involved Aboriginal people. Similar proportions of Aboriginal (76%) and non-Aboriginal (79%) people had undergone surgical treatment. Colorectal cancer-specific survival was similar for Aboriginal and non-Aboriginal people up to 18 months after diagnosis, but 5 years post-diagnosis the risk of death for Aboriginal people who had had surgical treatment was 68% higher than for non-Aboriginal people (adjusted hazards ratio, 1.68; 95% CI, 1.32-2.09). Of 145 Aboriginal people with colorectal cancer identified by the medical records audit, 117 (81%) had undergone surgery, and 56 (48%) had also received adjuvant chemotherapy and/or radiotherapy.

CONCLUSIONS

Aboriginal people with colorectal cancer had poorer survival rates than non-Aboriginal people, although rates of surgical treatment, complications and follow-up colonoscopy were similar. More work is needed to identify and understand why outcomes for Aboriginal people with colorectal cancer are different from those of other New South Wales residents.

Prostate cancer mortality outcomes and patterns of primary treatment for Aboriginal men in New South Wales, Australia

OBJECTIVE

To compare prostate cancer mortality for Aboriginal and non-Aboriginal men and to describe prostate cancer treatments received by Aboriginal men.

PATIENTS AND METHODS

We analysed cancer registry records for all men diagnosed with prostate cancer in New South Wales (NSW) in 2001-2007 linked to hospital inpatient episodes and deaths. More detailed information on androgen-deprivation therapy and radiotherapy was obtained from medical records for 87 NSW Aboriginal men diagnosed in 2000-2011. The main outcomes were primary treatment for, and death from, prostate cancer. Analysis included Cox proportional hazards regression and logistic regression.

RESULTS

There were 259 Aboriginal men among 35,214 prostate cancer cases diagnosed in 2001-2007. Age and spread of disease at diagnosis were similar for Aboriginal and non-Aboriginal men. Prostate cancer mortality 5 years after diagnosis was higher for Aboriginal men (17.5%, 95% confidence interval (CI) 12.4-23.3) than non-Aboriginal men (11.4%, 95% CI 11.0-11.8). Aboriginal men were 49% more likely to die from prostate cancer (hazard ratio 1.49, 95% CI 1.07-1.99) after adjusting for differences in demographic factors, stage at diagnosis, health access and comorbidities. Aboriginal men were less likely to have a prostatectomy for localised or regional cancer than non-Aboriginal men (adjusted odds ratio 0.60, 95% CI 0.40-0.91). Of 87 Aboriginal men with full staging and treatment information, 60% were diagnosed with localised disease. Of these, 38% had a prostatectomy (± radiotherapy), 29% had radiotherapy only and 33% had neither.

CONCLUSION

More research is required to explain differences in treatment and mortality for Aboriginal men with prostate cancer compared with non-Aboriginal men. In the meantime, ongoing monitoring and efforts are needed to ensure Aboriginal men have equitable access to best care.

Increasing rates of surgical treatment and preventing comorbidities may increase breast cancer survival for Aboriginal women

Background

Lower breast cancer survival has been reported for Australian Aboriginal women compared to non-Aboriginal women, however the reasons for this disparity have not been fully explored. We compared the surgical treatment and survival of Aboriginal and non-Aboriginal women diagnosed with breast cancer in New South Wales (NSW), Australia.

Methods

We analysed NSW cancer registry records of breast cancers diagnosed in 2001–2007, linked to hospital inpatient episodes and deaths. We used unconditional logistic regression to compare the odds of Aboriginal and non-Aboriginal women receiving surgical treatment. Breast cancer-specific survival was examined using cumulative mortality curves and Cox proportional hazards regression models.

Results

Of the 27 850 eligible women, 288 (1.03%) identified as Aboriginal. The Aboriginal women were younger and more likely to have advanced spread of disease when diagnosed than non-Aboriginal women. Aboriginal women were less likely than non-Aboriginal women to receive surgical treatment (odds ratio 0.59, 95% confidence interval (CI) 0.42-0.86). The five-year crude breast cancer-specific mortality was 6.1% higher for Aboriginal women (17.7%, 95% CI 12.9-23.2) compared with non-Aboriginal women (11.6%, 95% CI 11.2-12.0). After accounting for differences in age at diagnosis, year of diagnosis, spread of disease and surgical treatment received the risk of death from breast cancer was 39% higher in Aboriginal women (HR 1.39, 95% CI 1.01-1.86). Finally after also accounting for differences in comorbidities, socioeconomic disadvantage and place of residence the hazard ratio was reduced to 1.30 (95% CI 0.94-1.75).

Conclusion

Preventing comorbidities and increasing rates of surgical treatment may increase breast cancer survival for NSW Aboriginal women.
