Rights, interests and expectations: Indigenous perspectives on unrestricted access to genomic data.

Addressing Indigenous rights and interests in genetic resources has become increasingly challenging in an open science environment that promotes unrestricted access to genomic data. Although Indigenous experiences with genetic research have been shaped by a series of negative interactions, there is increasing recognition that equitable benefits can only be realized through greater participation of Indigenous communities. Issues of trust, accountability and equity underpin Indigenous critiques of genetic research and the sharing of genomic data. This Perspectives article highlights identified issues for Indigenous communities around the sharing of genomic data and suggests principles and actions that genomic researchers can adopt to recognize community rights and interests in data.

Atrial fibrillation incidence and outcomes in two cohorts of octogenarians: LiLACS NZ.

BACKGROUND: Atrial fibrillation (AF), the most common cardiac arrhythmia in the general population, has significant healthcare burden. Little is known about AF in octogenarians. OBJECTIVE: To describe the prevalence and incidence rate of AF in New Zealand (NZ) octogenarians and the risk of stroke and mortality at 5-year follow-up. DESIGN: Longitudinal Cohort Study. SETTING: Bay of Plenty and Lakes health regions of New Zealand. SUBJECTS: Eight-hundred-seventy-seven (379 indigenous Maori, 498 non-Maori) were included in the analysis. METHODS: AF, stroke/TIA events and relevant co-variates were established annually using self-report and hospital records (and ECG for AF). Cox proportional-hazards regression models were used to determine the time dependent AF risk of stroke/TIA. RESULTS: AF was present in 21% at baseline (Maori 26%, non-Maori 18%), the prevalence doubled over 5-years (Maori 50%, non-Maori 33%). 5-year AF incidence was 82.6 /1000-person years and at all times AF incidence for Maori was twice that of non-Maori. Five-year stroke/TIA prevalence was 23% (22% in Maori and 24% non- Maori), higher in those with AF than without. AF was not independently associated with 5-year new stroke/TIA; baseline systolic blood pressure was. Mortality was higher for Maori, men, those with AF and CHF and statin use was protective. In summary, AF is more prevalent in indigenous octogenarians and should have an increased focus in health care management. Further research could examine treatment in more detail to facilitate ethnic specific impact and risks and benefits of treating AF in octogenarians.

Optimising function and well-being in older adults: protocol for an integrated research programme in Aotearoa/New Zealand.

BACKGROUND: Maintaining independence is of key importance to older people. Ways to enable health strategies, strengthen and support whanau (family) at the community level are needed. The Ageing Well through Eating, Sleeping, Socialising and Mobility (AWESSOM) programme in Aotearoa/New Zealand (NZ) delivers five integrated studies across different ethnicities and ages to optimise well-being and to reverse the trajectory of functional decline and dependence associated with ageing. METHODS: Well-being, independence and the trajectory of dependence are constructs viewed differently according to ethnicity, age, and socio-cultural circumstance. For each AWESSoM study these constructs are defined and guide study development through collaboration with a wide range of stakeholders, and with reference to current evidence. The Compression of Functional Decline model (CFD) underpins aspects of the programme. Interventions vary to optimise engagement and include a co-developed whanau (family) centred initiative (Nga Pou o Rongo), the use of a novel LifeCurve™App to support behavioural change, development of health and social initiatives to support Pacific elders, and the use of a comprehensive oral health and cognitive stimulation programme for cohorts in aged residential care. Running parallel to these interventions is analysis of large data sets from primary care providers and national health databases to understand complex multi-morbidities and identify those at risk of adverse outcomes. Themes or target areas of sleep, physical activity, oral health, and social connectedness complement social capital and community integration in a balanced programme involving older people across the ability spectrum. DISCUSSION: AWESSoM delivers a programme of bespoke yet integrated studies. Outcomes and process analysis from this research will inform about novel approaches to implement relevant, socio-cultural interventions to optimise well-being and health, and to reverse the trajectory of decline experienced with age. TRIAL REGISTRATION: The At-risk cohort study was registered by the Australian New Zealand Clinical Trials registry on 08/12/2021 (Registration number ACTRN 12621001679875 ).

Cultural context in New Zealand: incorporating kaupapa Maori values in clinical research and practice.

We examined the importance of understanding and incorporating cultural context within Aotearoa/New Zealand when engaging in clinical research and practice. This paper reports on the qualitative findings of a mixed methods study aimed at determining what effect a cardiac risk reduction exercise and lifestyle management programme, embedded within a kaupapa Maori methodological approach, had on Maori participants. This methodology saw participants able to redevelop a western model cardiac risk reduction programme by introducing a Maori worldview. Our study revealed how the kaupapa Maori approach empowered participants to examine and evaluate not only their own health and lifestyle choices, but those of family and the wider community. Combining biomedical and kaupapa Maori components into the programme was found to benefit participants' mental, physical, spiritual and family well-being.

Navigating the space between co-design and mahitahi: Building bridges between knowledge systems on behalf of communities.

AIMS: To provide knowledge and recommendations for researchers, health professionals and policymakers on navigating between science and matauranga (knowledge) Maori when using co-design methodologies. CONTEXT: It is well known that the health system in Aotearoa/New Zealand does not provide culturally responsive services, programmes or approaches. Indigenous, remote and vulnerable populations that are not well served by medical and scientific models would be better served by the underlying premise of co-design methodology. However, co-design is a Western methodology. Mahitahi is presented here as a culturally responsive method of co-design that builds approaches by utilising the worldview of the people that the health system most needs to have impact upon. Co-design and mahitahi have synergies, and working at the interface between Western and Maori knowledge systems can provide innovative solutions that draw on the strengths of both approaches. APPROACH: Authors will outline the benefit co-design processes have for improving health outcomes for remote and vulnerable populations. Mahitahi will be described and the synergies with co-design emphasised with important distinctions also highlighted. The use of Indigenous knowledge systems, using Maori as the case example, will be outlined. CONCLUSION: Recommendations will be provided to guide researchers, health professionals and policy makers when planning a co-design approach with remote and vulnerable communities.

Ha Ora: secondary care barriers and enablers to early diagnosis of lung cancer for Maori communities.

BACKGROUND: Lung Cancer is the leading cause of cancer deaths in Aotearoa New Zealand. Maori communities in particular have higher incidence and mortality rates from Lung Cancer. Diagnosis of lung cancer at an early stage can allow for curative treatment. This project aimed to document the barriers to early diagnosis and treatment of lung cancer in secondary care for Maori communities. METHODS: This project used a kaupapa Maori approach. Nine community hui (focus groups) and nine primary healthcare provider hui were carried out in five rural localities in the Midland region. Community hui included cancer patients, whanau (families), and other community members. Healthcare provider hui comprised staff members at the local primary healthcare centre, including General Practitioners and nurses. Hui data were thematically analysed. RESULTS: Barriers and enablers to early diagnosis of lung cancer were categorised into two broad themes: Specialist services and treatment, and whanau journey. The barriers and enablers that participants experienced in specialist services and treatment related to access to care, engagement with specialists, communication with specialist services and cultural values and respect, whereas barriers and enablers relating to the whanau journey focused on agency and the impact on whanau. CONCLUSIONS: The study highlighted the need to improve communication within and across healthcare services, the importance of understanding the cultural needs of patients and whanau and a health system strategy that meets these needs. Findings also demonstrated the resilience of Maori and the active efforts of whanau as carers to foster health literacy in future generations.

Anaemia and physical and mental health in the very old: An individual participant data meta-analysis of four longitudinal studies of ageing.

OBJECTIVE: To determine the physical and mental health of very old people (aged 80+) with anaemia. METHODS: Individual level meta-analysis from five cohorts of octogenarians (n = 2,392): LiLACS NZ Maori, LiLACS NZ non-Maori, Leiden 85-plus Study, Newcastle 85+ Study, and TOOTH. Mixed models of change in functional ability, cognitive function, depressive symptoms, and self-rated health over time were separately fitted for each cohort. We combined individual cohort estimates of differences according to the presence of anaemia at baseline, adjusting for age at entry, sex, and time elapsed. Combined estimates are presented as differences in standard deviation units (i.e. standardised mean differences-SMDs). RESULTS: The combined prevalence of anaemia was 30.2%. Throughout follow-up, participants with anaemia, on average, had: worse functional ability (SMD -0.42 of a standard deviation across cohorts; CI -0.59,-0.25); worse cognitive scores (SMD -0.27; CI -0.39,-0.15); worse depression scores (SMD -0.20; CI -0.31,-0.08); and lower ratings of their own health (SMD -0.36; CI -0.47,-0.25). Differential rates of change observed were: larger declines in functional ability for those with anaemia (SMD -0.12 over five years; CI -0.21,-0.03) and smaller mean difference in depression scores over time between those with and without anaemia (SMD 0.18 over five years; CI 0.05,0.30). CONCLUSION: Anaemia in the very old is a common condition associated with worse functional ability, cognitive function, depressive symptoms, and self-rated health, and a more rapid decline in functional ability over time. The question remains as to whether anaemia itself contributes to worse outcomes or is simply a marker of chronic diseases and nutrient deficiencies.

Indigenous perspectives on breaking bad news: ethical considerations for healthcare providers.

Most healthcare providers (HCPs) work from ethical principles based on a Western model of practice that may not adhere to the cultural values intrinsic to Indigenous peoples. Breaking bad news (BBN) is an important topic of ethical concern in health research. While much has been documented on BBN globally, the ethical implications of receiving bad news, from an Indigenous patient perspective in particular, is an area that requires further inquiry. This article discusses the experiences of Maori (Indigenous peoples of New Zealand) lung cancer patients and their families, in order to investigate the ethical implications of receiving bad news. Data collection occurred through 23 semistructured interviews and nine focus groups with Maori lung cancer patients and their families in four districts in the Midland Region of New Zealand: Waikato, Bay of Plenty, Lakes and Tairawhiti. The findings of this study were categorised into two key themes: communication and context. Avenues for best practice include understanding the centrality of the HCP-patient relationship and family ties in the healthcare journey, and providing patients with the full range of viable treatment options including hope, clear advice and guidance when the situation calls for it. Overall, the findings of this study hold implications for providing culturally safe and humanistic cancer care when BBN to Maori and Indigenous patients.

Ha Ora: Barriers and enablers to early diagnosis of lung cancer in primary healthcare for Maori communities.

OBJECTIVE: The objective of this research was to document the barriers to early presentation and diagnosis of lung cancer within primary healthcare, identified by Maori whanau (families) and primary healthcare providers in the Midland region of Aotearoa New Zealand. METHODS: This project used a kaupapa Maori approach. Nine community hui (focus groups) and nine primary healthcare provider hui were carried out in five rural localities in the Midland region. Each community hui included cancer patients, whanau, and other community members. Each healthcare provider hui comprised staff members at the local primary healthcare centre, including General Practitioners and nurses. Hui data were thematically analysed. RESULTS: Barriers and enablers to early diagnosis of lung cancer were categorised into three key themes: GP relationship and position in the community, health literacy and pathways to diagnosis. CONCLUSION: This study demonstrates that culturally responsive, patient-centred healthcare, and positive GP-patient relationships are significant factors for Maori patients and whanau serving as barriers and enablers to early diagnosis of lung cancer.

Maori, Pacific, Aboriginal and Torres Strait Islander Women's Cardiovascular Health: Where Are the Opportunities to Make a Real Difference?

Maori and Pacific women in New Zealand and Aboriginal and Torres Strait Islander women in Australia are recognised as nurturers and leaders within their families and communities. However, women's wellbeing, and that of their communities, are affected by a high burden of cardiovascular disease experienced at a younger age than women from other ethnic groups. There has been little focus on the cardiovascular outcomes and strategies to address heart health inequities among Maori, Pacific, Aboriginal and Torres Strait Islander women. The factors contributing to these inequities are complex and interrelated but include differences in exposure to risk and protective factors, rates of multi-morbidity, and substantial gaps within the health system, which include barriers to culturally responsive, timely and appropriate cardiovascular care. Evidence demonstrates critical treatment gaps across the continuum of risk and disease, including assessment and management of cardiovascular risk in young women and time-critical access to and receipt of acute services. Cardiovascular disease in women impacts not only the individual, but their family and community, and the burden of living with disease limits women's capacity to fulfil their roles and responsibilities which support and sustain families and communities. Our response must draw on the strengths of Maori, Pacific, Aboriginal and Torres Strait Islander women, acknowledge health and wellbeing holistically, address the health and social needs of individuals, families and communities, and recognise that Indigenous women in New Zealand, Australia and across the Pacific must be involved in the design, development and implementation of solutions affecting their own health.

Does potentially inappropriate prescribing predict an increased risk of admission to hospital and mortality? A longitudinal study of the 'oldest old'.

BACKGROUND: Potentially inappropriate prescribing (PIP) is associated with negative health outcomes, including hospitalisation and mortality. Life and Living in Advanced Age: a Cohort Study in New Zealand (LiLACS NZ) is a longitudinal study of Maori (the indigenous population of New Zealand) and non-Maori octogenarians. Health disparities between indigenous and non-indigenous populations are prevalent internationally and engagement of indigenous populations in health research is necessary to understand and address these disparities. Using LiLACS NZ data, this study reports the association of PIP with hospitalisations and mortality prospectively over 36-months follow-up. METHODS: PIP, from pharmacist applied criteria, was reported as potentially inappropriate medicines (PIMs) and potential prescribing omissions (PPOs). The association between PIP and hospitalisations (all-cause, cardiovascular disease-specific and ambulatory-sensitive) and mortality was determined throughout a series of 12-month follow-ups using binary logistic (hospitalisations) and Cox (mortality) regression analysis, reported as odds ratios (ORs) and hazard ratios (HRs), respectively, and the corresponding confidence intervals (CIs). RESULTS: Full demographic data were obtained for 267 Maori and 404 non-Maori at baseline, 178 Maori and 332 non-Maori at 12-months, and 122 Maori and 281 non-Maori at 24-months. The prevalence of any PIP (i.e. ≥1 PIM and/or PPO) was 66, 75 and 72% for Maori at baseline, 12-months and 24-months, respectively. In non-Maori, the prevalence of any PIP was 62, 71 and 73% at baseline, 12-months and 24-months, respectively. At each time-point, there were more PPOs than PIMs; at baseline Maori were exposed to a significantly greater proportion of PPOs compared to non-Maori (p = 0.02). In Maori: PPOs were associated with a 1.5-fold increase in hospitalisations and mortality. In non-Maori, PIMs were associated with a double risk of mortality. CONCLUSIONS: PIP was associated with an increased risk of hospitalisation and mortality in this cohort. Omissions appear more important for Maori in predicting hospitalisations, and PIMs were more important in non-Maori in predicting mortality. These results suggest understanding prescribing outcomes across and between population groups is needed and emphasises prescribing quality assessment is useful.

Quality of prescribing predicts hospitalisation in octogenarians: life and living in advanced age: a cohort study in New Zealand (LiLACS NZ).

BACKGROUND: Prescribing for older people is complex, and many studies have highlighted that appropriate prescribing in this cohort is not always achieved. However, the long-term effect of inappropriate prescribing on outcomes such as hospitalisation and mortality has not been demonstrated. The aim of this study was to determine the level of potentially inappropriate prescribing (PIP) for participants of the Life and Living in Advanced Age: A Cohort Study in New Zealand (LiLACS NZ) study at baseline and examine the association between PIP and hospitalisation and mortality at 12-months follow-up. METHODS: PIP was determined using STOPP/START. STOPP identified potentially inappropriate medicines (PIMs) prescribed, START identified potential prescribing omissions (PPOs). STOPP/START were applied to all LiLACS NZ study participants, a longitudinal study of ageing, which includes 421 Maori aged 80-90 years and 516 non-Maori aged 85 years. Participants' details (e.g. age, sex, living arrangements, socioeconomic status, physical functioning, medical conditions) were gathered by trained interviewers. Some participants completed a core questionnaire only, which did not include medications details. Medical conditions were established from a combination of self-report, review of hospital discharge and general practitioner records. Binary logistic regression, controlled for multiple potential confounders, was conducted to determine if either PIMs or PPOs were associated with hospital admissions and mortality (p < 0.05 was considered significant). RESULTS: Full data were obtained for 267 Maori and 404 non-Maori. The mean age for Maori was 82.3(±2.6) years, and 84.6(±0.53) years for non-Maori. 247 potentially inappropriate medicines were identified, affecting 24.3% Maori and 28.0% non-Maori. PIMs were not associated with 12-month mortality or hospitalisation for either cohort (p > 0.05; adjusted models). 590 potential prescribing omissions were identified, affecting 58.1% Maori and 49.0% non-Maori. PPOs were associated with hospitalisation (p = 0.001 for Maori), but were not associated with risk of mortality (p > 0.05) for either cohort within the 12-month follow-up (adjusted models). CONCLUSION: PPOs were more common than PIMs and were associated with an increased risk of hospitalisation for Maori. This study highlights the importance of carefully considering all indicated medicines when deciding what to prescribe. Further follow-up is necessary to determine the long-term effects of PIP on mortality and hospitalisation.

Study protocol of a randomised controlled trial to examine the impact of a complex intervention in pre-frail older adults.

BACKGROUND: Frailty is a multidimensional geriatric syndrome associated with functional loss. The Senior Chef (SC, nutrition) and SAYGO (strength and balance exercise) programmes are well accepted among older adults but the impact of each, or a combination of both, on the frailty syndrome in pre-frail older adults is unknown. AIMS: To determine the effectiveness and cost-effectiveness of a complex intervention consisting of the SC and/or SAYGO programmes to prevent progression of frailty in pre-frail older adults. METHODS: A multi-centre randomised controlled assessor-blinded study. The four intervention groups are SC, an 8-week nutrition education and cooking class; SAYGO, a 10-week strength and balance exercise class; SC plus SAYGO, and a social group (Control). Community-dwelling adults aged 75+ (60 + Maori and Pasifika) in New Zealand are recruited through health providers. Participants are not terminally ill or with advanced dementia, and have a score of 1 or 2 on the FRAIL questionnaire. Baseline assessments are completed using standardised questionnaires prior to randomisation. Four follow-up assessments are completed: immediately after intervention, 6, 12 and 24 months post-intervention. The primary outcome is frailty score, secondary outcomes are falls, physical function, quality of life, food intake, physical activity, and sustainability of the strategy. Study outcomes will be analysed using intention-to-treat approach. Cost analyses will be completed to determine if interventions are cost effective relative to the control group. DISCUSSION: This trial is designed to be a real world rigorous assessment of whether the two intervention strategies can prevent progression of frailty in older people. If successful, this will generate valuable information about effectiveness of this nutrition and exercise strategy, and provide insights for their implementation. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry number-ACTRN12614000827639.

Patterns of multi-morbidity and prediction of hospitalisation and all-cause mortality in advanced age.

Background: multi-morbidity is associated with poor outcomes and increased healthcare utilisation. We aim to identify multi-morbidity patterns and associations with potentially inappropriate prescribing (PIP), subsequent hospitalisation and mortality in octogenarians. Methods: life and Living in Advanced Age; a Cohort Study in New Zealand (LiLACS NZ) examined health outcomes of 421 Maori (indigenous to New Zealand), aged 80-90 and 516 non-Maori, aged 85 years in 2010. Presence of 14 chronic conditions was ascertained from self-report, general practice and hospitalisation records and physical assessments. Agglomerative hierarchical cluster analysis identified clusters of participants with co-existing conditions. Multivariate regression models examined the associations between clusters and PIP, 48-month hospitalisations and mortality. Results: six clusters were identified for Maori and non-Maori, respectively. The associations between clusters and outcomes differed between Maori and non-Maori. In Maori, those in the complex multi-morbidity cluster had the highest prevalence of inappropriately prescribed medications and in cluster 'diabetes' (20% of sample) had higher risk of hospitalisation and mortality at 48-month follow-up. In non-Maori, those in the 'depression-arthritis' (17% of the sample) cluster had both highest prevalence of inappropriate medications and risk of hospitalisation and mortality. Conclusions: in octogenarians, hospitalisation and mortality are better predicted by profiles of clusters of conditions rather than the presence or absence of a specific condition. Further research is required to determine if the cluster approach can be used to target patients to optimise resource allocation and improve outcomes.

End Users Want Alternative Intervention Delivery Models: Usability and Acceptability of the REMOTE-CR Exercise-Based Cardiac Telerehabilitation Program.

OBJECTIVE: Evaluate user experiences of an exercise-based cardiac telerehabilitation intervention (REMOTE-CR) that provided near universal access to real-time remote coaching and behavioral support from exercise specialists. DESIGN: Secondary analysis (12-week follow-up) of a parallel group, single blind, randomized controlled noninferiority trial (ACTRN12614000843651). SETTING: Community-based cardiac rehabilitation. PARTICIPANTS: Adults (N=162) with coronary heart disease who were eligible for outpatient cardiac rehabilitation. Eighty-two of 162 trial participants were randomized to receive REMOTE-CR; 67 completed usability and acceptability assessment at 12-week follow-up. INTERVENTION: REMOTE-CR comprised 12 weeks of individualized exercise prescription, real-time physiological monitoring, coaching, and behavioral support, delivered via a bespoke telerehabilitation platform. OUTCOMES: Ease of use, satisfaction with the technology platform and intervention content, and demand for real-world implementation as an alternative to traditional center-based programs were assessed at 12-week follow-up. RESULTS: Components of usability and acceptability were positively evaluated by most participants (44-66 of 67, 66%-99%). Fifty-eight of 67 (87%) would choose REMOTE-CR if it was available as a usual care service, primarily because it provides convenient and flexible access to real-time individualized support from exercise specialists. Technology challenges were rare and had little effect on user experiences or demand for REMOTE-CR. CONCLUSIONS: REMOTE-CR can extend the reach and impact of existing cardiac rehabilitation services by overcoming traditional participation barriers while preserving expert oversight. Adoption of emerging technologies should be accelerated to support dynamic, engaging, individualized intervention delivery models, but optimizing overall cardiac rehabilitation participation rates will require multiple delivery models that are tailored to satisfy diverse participant preferences.

Burden of atrial fibrillation in Maori and Pacific people in New Zealand: a cohort study.

BACKGROUND: Atrial fibrillation (AF) is a major risk factor for ischaemic stroke and cardiovascular events. In New Zealand (NZ), Maori (indigenous New Zealanders) and Pacific people experience higher rates of AF compared with non-Maori/non-Pacific people. AIM: To describe a primary care population with AF in NZ. Stroke risk and medication adherence according to ethnicity are also detailed. METHODS: Electronic medical records for adults (≥20 years, n = 135 840, including 19 918 Maori and 43 634 Pacific people) enrolled at 37 NZ general practices were analysed for AF diagnosis and associated medication prescription information. RESULTS: The overall prevalence of non-valvular AF (NVAF) in this population was 1.3% (1769), and increased with age (4.4% in people ≥55 years). Maori aged ≥55 years were more likely to be diagnosed with NVAF (7.3%) than Pacific (4.0%) and non-Maori/non-Pacific people (4.1%, P < 0.001). Maori and Pacific NVAF patients were diagnosed with AF 10 years earlier than non-Maori/non-Pacific patients (median age of diagnosis: Maori = 60 years, Pacific = 61 years, non-Maori/non-Pacific = 71 years, P < 0.001). Overall, 67% of NVAF patients were at high risk for stroke (CHA2 DS2 -VASc ≥ 2) at the time of AF diagnosis. Almost half (48%) of Maori and Pacific NVAF patients aged <65 years were at high risk for stroke, compared with 22% of non-Maori/non-Pacific (P < 0.001). Irrespective of ethnic group, adherence to AF medication was suboptimal in those NVAF patients with a high risk of stroke or with stroke history. CONCLUSION: AF screening and stroke thromboprophylaxis in Maori and Pacific people could start below the age of 65 years in NZ.

Physical Activity, Function, and Mortality in Advanced Age: A Longitudinal Follow-Up (LiLACS NZ).

The relationship between physical activity, function, and mortality is not established in advanced age. Physical activity, function, and mortality were followed in a cohort of Maori and non-Maori adults living in advanced age for a period of 6 years. Generalized linear regression models were used to analyze the association between physical activity and Nottingham Extended Activities of Daily Living scale, whereas Kaplan-Meier survival analysis and Cox proportional hazard models were used to assess the association between the physical activity and mortality. The hazard ratio for mortality for those in the least active physical activity quartile was 4.1 for Maori and 1.8 for non-Maori compared with the most active physical activity quartile. There was an inverse relationship between physical activity and mortality, with lower hazard ratios for mortality at all levels of physical activity. Higher levels of physical activity were associated with lower mortality and higher functional status in advanced-aged adults.

Clinical Characteristics and Burden of Risk Factors Among Patients With Early Onset Acute Coronary Syndromes: The ANZACS-QI New Zealand National Cohort (ANZACS-QI 17).

BACKGROUND: Cardiovascular (CV) risk factor profiles of people experiencing acute coronary syndromes (ACS) vary with age, and in New Zealand (NZ), Maori and people of Pacific Island descent typically present with ACS at a younger age. We aimed to explore age- and ethnicity-related differences in CV risk factors in a large NZ cohort with first-time ACS. METHODS: The All NZ Acute Coronary Syndrome Quality Improvement program (ANZACS-QI) registry collects comprehensive data for patients admitted with ACS at NZ hospitals. This analysis includes patients with no prior atherosclerotic CV disease enrolled from 1 July, 2012 to 30 June, 2015. RESULTS: 14,190 patients had confirmed ACS, 8493 (60%) patients with no prior CVD comprised the study cohort. The mean age was 64 years, 25% were aged <55years, and 66% were male. Those aged <55years were more likely than older patients to be current smokers (48% vs 19%), have higher body mass index (BMI) (48% vs 34% with BMI≥30kg/m2), and higher total cholesterol:HDL ratios (≥4.0, 70% vs 50%), all p<0.001. Sixteen per cent of those <55years had diabetes; these patients often had a BMI≥30kg/m2 (67%) and higher median HbA1c than older patients with diabetes (69mmol/mol vs 55mmol/mol). Maori and people of Pacific Island descent were overrepresented in the younger age group; these patients had a very high risk factor burden. CONCLUSIONS: A quarter of NZ patients admitted to hospital with a first-time CV disease event are aged <55years. Younger patients have a very high risk factor burden: half are current smokers, half have a BMI≥30kg/m2, and 16% have diabetes.

End of life care preferences among people of advanced age: LiLACS NZ.

BACKGROUND: Understanding end of life preferences amongst the oldest old is crucial to informing appropriate palliative and end of life care internationally. However, little has been reported in the academic literature about the end of life preferences of people in advanced age, particularly the preferences of indigenous older people, including New Zealand Maori. METHODS: Data on end of life preferences were gathered from 147 Maori (aged >80 years) and 291 non- Maori aged (>85 years), during three waves of Te Puawaitangi O Nga Tapuwae Kia Ora Tonu, Life and Living in Advanced Age (LiLACs NZ). An interviewer-led questionnaire using standardised tools and including Maori specific subsections was used. RESULTS: The top priority for both Maori and non-Maori participants at end of life was 'not being a burden to my family'. Interestingly, a home death was not a high priority for either group. End of life preferences differed by gender, however these differences were culturally contingent. More female Maori participants wanted spiritual practices at end of life than male Maori participants. More male non-Maori participants wanted to be resuscitated than female non- Maori participants. CONCLUSIONS: That a home death was not in the top three end of life priorities for our participants is not consistent with palliative care policy in most developed countries where place of death, and particularly home death, is a central concern. Conversely our participants' top concern - namely not being a burden - has received little research or policy attention. Our results also indicate a need to pay attention to diversity in end of life preferences amongst people of advanced age, as well as the socio-cultural context within which preferences are formulated.
