Cardiovascular disease risk assessment for Aboriginal and Torres Strait Islander adults aged under 35 years: a consensus statement.

Cardiovascular disease (CVD) is a leading cause of preventable morbidity and mortality in Aboriginal and Torres Strait Islander peoples. This statement from the Australian Chronic Disease Prevention Alliance, the Royal Australian College of General Practitioners, the National Aboriginal Community Controlled Health Organisation and the Editorial Committee for Remote Primary Health Care Manuals communicates the latest consensus advice of guideline developers, aligning recommendations on the age to commence Aboriginal and Torres Strait Islander CVD risk assessment across three guidelines. MAIN RECOMMENDATIONS: In Aboriginal and Torres Strait Islander peoples without existing CVD: CVD risk factor screening should commence from the age of 18 years at the latest, including for blood glucose level or glycated haemoglobin, estimated glomerular filtration rate, serum lipids, urine albumin to creatinine ratio, and other risk factors such as blood pressure, history of familial hypercholesterolaemia, and smoking status. Individuals aged 18-29 years with the following clinical conditions are automatically conferred high CVD risk: ▶type 2 diabetes and microalbuminuria; ▶moderate to severe chronic kidney disease; ▶systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg; ▶familial hypercholesterolaemia; or ▶serum total cholesterol > 7.5 mmol/L. Assessment using the National Vascular Disease Prevention Alliance absolute CVD risk algorithm should commence from the age of 30 years at the latest - consider upward adjustment of calculated CVD risk score, accounting for local guideline use, risk factor and CVD epidemiology, and clinical discretion. Assessment should occur as part of an annual health check or opportunistically. Subsequent review should be conducted according to level of risk. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: From age 18 years (at the latest), Aboriginal and Torres Strait Islander adults should undergo CVD risk factor screening, and from age 30 years (at the latest), they should undergo absolute CVD risk assessment using the NVDPA risk algorithm.

Exploring pathways to mental healthcare for urban Aboriginal young people: a qualitative interview study.

OBJECTIVES: To explore the perceptions of Aboriginal Community Controlled Health Service (ACCHS) staff involved in providing mental healthcare to Aboriginal young people of the current and ideal pathways to mental healthcare for urban Aboriginal young people attending ACCHSs, and to identify what additional supports staff may need to provide optimal mental healthcare to Aboriginal young people. DESIGN: Qualitative interview study conducted during May 2016-2017. SETTING: Primary care, at two ACCHSs participating in the Study of Environment on Aboriginal Resilience and Child Health in New South Wales. PARTICIPANTS: Purposive sampling of staff involved in mental healthcare pathways of Aboriginal young people, including general practitioners (GPs), nurses and Aboriginal Health Workers (AHWs). RESULTS: All individuals approached for interview (n=21) participated in the study. Four overarching themes and seven sub-themes were identified: availability and use of tools in practice (valuing training and desire for tools and established pathways), targeting the ideal care pathway (initiating care and guiding young people through care), influencing the care pathway (adversities affecting access to care and adapting the care pathway) and assessing future need (appraising service availability). CONCLUSIONS: Participants desired screening tools, flexible guidelines and training for healthcare providers to support pathways to mental healthcare for Aboriginal young people. Both GPs and AHWs were considered key in identifying children at risk and putting young people onto a pathway to receive appropriate mental healthcare. AHWs were deemed important in keeping young people on the care pathway, and participants felt care pathways could be improved with the addition of dedicated child and adolescent AHWs. The ACCHSs were highlighted as essential to providing culturally appropriate care for Aboriginal young people experiencing mental health problems, and funding for mental health specialists to be based at the ACCHSs was considered a priority.

Absolute cardiovascular disease risk and lipid-lowering therapy among Aboriginal and Torres Strait Islander Australians.

OBJECTIVE: To quantify absolute cardiovascular disease (CVD) risk in Aboriginal and Torres Strait Islander people and their use of lipid-lowering therapies. DESIGN, PARTICIPANTS: Cross-sectional analysis of nationally representative data from 2820 participants aged 18-74 years who provided biomedical data for the National Aboriginal and Torres Strait Islander Health Measures Survey component of the 2012-13 Australian Aboriginal and Torres Strait Islander Health Survey. MAIN OUTCOME MEASURES: Prior CVD and use of lipid-lowering medications were ascertained at interview. 5-year absolute risk of a primary CVD event was calculated with the Australian National Vascular Disease Prevention Alliance algorithm, with categories low (< 10%), moderate (10-15%) and high risk (> 15%). RESULTS: Among participants aged 35-74 years, 9.6% (95% CI, 7.2-12.0%) had prior CVD; 15.7% (95% CI, 13.0-18.3%) were at high, 4.9% (95% CI, 3.3-6.6%) at moderate, and 69.8% (95% CI, 66.8-72.8%) at low absolute primary CVD risk. 82.6% of those at high primary risk were identified on the basis of clinical criteria. High primary absolute risk affected 1.1% (95% CI, 0.0-2.5%) of 18-24-year-olds, 4.7% (95% CI, 2.0-7.5%) of 25-34-year-olds, and 44.2% (95% CI, 33.1-55.3%) of 65-74-year-olds. Lipid-lowering therapy was being used by 52.9% (95% CI, 38.2-67.6%) of people aged 35-74 years with prior CVD and by 42.2% (95% CI, 30.5-53.8%) of those at high primary CVD risk. CONCLUSION: Absolute CVD risk is high among Aboriginal and Torres Strait Islander people, and most of those at high risk are undertreated. Substantial proportions of people under 35 years of age are at high risk, but are not targeted by current guidelines for absolute CVD risk assessment, compromising CVD prevention in this population.

Housing conditions associated with recurrent gastrointestinal infection in urban Aboriginal children in NSW, Australia: findings from SEARCH.

OBJECTIVE: To examine the associations between housing and gastrointestinal infection in Aboriginal children in urban New South Wales. METHODS: A total of 1,398 Aboriginal children were recruited through four Aboriginal Community Controlled Health Services. Multilevel regression modelling of survey data estimated associations between housing conditions and recurrent gastrointestinal infection, adjusting for sociodemographic and health factors. RESULTS: Of the sample, 157 children (11%) had recurrent gastrointestinal infection ever and 37 (2.7%) required treatment for recurrent gastrointestinal infection in the past month. Children in homes with 3+ housing problems were 2.51 (95% CrI 1.10, 2.49) times as likely to have recurrent gastrointestinal infection ever and 6.79 (95% CrI 2.11, 30.17) times as likely to have received recent treatment for it (versus 0-2 problems). For every additional housing problem, the prevalence of recurrent gastrointestinal infection ever increased by a factor of 1.28 (95% CrI 1.14, 1.47) and the prevalence of receiving treatment for gastrointestinal infection in the past month increased by a factor of 1.64 (95% CrI 1.20, 2.48). CONCLUSIONS: Housing problems were independently associated with recurrent gastrointestinal infection in a dose-dependent manner. Implications for public health: The role of housing as a potential determinant of health in urban Aboriginal children merits further attention in research and policy settings.

Relation of child, caregiver, and environmental characteristics to childhood injury in an urban Aboriginal cohort in New South Wales, Australia.

OBJECTIVE: Despite being disproportionately affected by injury, little is known about factors associated with injury in Aboriginal children. We investigated factors associated with injury among urban Aboriginal children attending four Aboriginal Community Controlled Health Services in New South Wales, Australia. METHODS: We examined characteristics of caregiver-reported child injury, and calculated prevalence ratios of 'ever-injury' by child, family, and environmental factors. RESULTS: Among children in the cohort, 29% (n=373/1,303) had ever broken a bone, been knocked out, required stitches or been hospitalised for a burn or poisoning; 40-78% of first injuries occurred at home and 60-91% were treated in hospital. Reported ever-injury was significantly lower (prevalence ratio ≤0.80) among children who were female, younger, whose caregiver had low psychological distress and had not been imprisoned, whose family experienced few major life events, and who hadn't experienced alcohol misuse in the household or theft in the community, compared to other cohort members. CONCLUSIONS: In this urban Aboriginal child cohort, injury was common and associated with measures of family and community vulnerability. Implications for public health: Prevention efforts targeting upstream injury determinants and Aboriginal children living in vulnerable families may reduce child injury. Existing broad-based intervention programs for vulnerable families may present opportunities to deliver targeted injury prevention.

Housing conditions of urban households with Aboriginal children in NSW Australia: tenure type matters.

BACKGROUND: Housing is a key determinant of the poor health of Aboriginal Australians. Most Aboriginal people live in cities and large towns, yet research into housing conditions has largely focused on those living in remote areas. This paper measures the prevalence of housing problems amongst participants in a study of urban Aboriginal families in New South Wales, Australia, and examines the relationship between tenure type and exposure to housing problems. METHODS: Cross-sectional survey data was provided by 600 caregivers of 1406 Aboriginal children aged 0-17 years participating in Phase One of the Study of Environment on Aboriginal Resilience and Child Health (SEARCH). Regression modelling of the associations between tenure type (own/mortgage, private rental or social housing) and housing problems was conducted, adjusting for sociodemographic factors. RESULTS: The majority (60%) of SEARCH households lived in social housing, 21% rented privately and 19% either owned their home outright or were paying a mortgage ("owned"). Housing problems were common, particularly structural problems, damp and mildew, vermin, crowding and unaffordability. Physical dwelling problems were most prevalent for those living in social housing, who were more likely to report three or more physical dwelling problems than those in owned (PR 3.19, 95%CI 1.97, 5.73) or privately rented homes (PR 1.49, 1.11, 2.08). However, those in social housing were the least likely to report affordability problems. Those in private rental moved home most frequently; children in private rental were more than three times as likely to have lived in four or more homes since birth than those in owned homes (PR 3.19, 95%CI 1.97, 5.73). Those in social housing were almost half as likely as those in private rental to have lived in four or more homes since birth (PR 0.56, 95%CI 0.14, 0.77). Crowding did not vary significantly by tenure type. CONCLUSIONS: The high prevalence of housing problems amongst study participants suggests that urban Aboriginal housing requires further attention as part of efforts to reduce the social and health disadvantage experienced by Aboriginal Australians. Particular attention should be directed to the needs of those renting in the private and social housing sectors, who are experiencing the poorest dwelling conditions.

Perspectives on childhood resilience among the Aboriginal community: an interview study.

OBJECTIVE: To describe Aboriginal community members' perspectives on the outcomes and origins of resilience among Aboriginal children. METHODS: Face-to-face interviews were conducted with 36 Aboriginal adults (15 health service professionals, 8 youth workers and 13 community members) at two urban and one regional Aboriginal Community Controlled Health Service in New South Wales. Interviews were transcribed and analysed thematically. RESULTS: We identified six themes: withstanding risk (displaying normative development, possessing inner fortitude); adapting to adversity (necessary endurance, masking inner vulnerabilities); positive social influences (secure family environments, role modelling healthy behaviours and relationships); instilling cultural identity (investing in Aboriginal knowledge, building a strong cultural self-concept); community safeguards (offering strategic sustainable services, holistic support, shared responsibility, providing enriching opportunities); and personal empowerment (awareness of positive pathways, developing self-respect, fostering positive decision making). CONCLUSIONS: Community members believed that resilient Aboriginal children possessed knowledge and self-belief that encouraged positive decision making despite challenging circumstances. A strong sense of cultural identity and safe, stable and supportive family environments were thought to promote resilient behaviours. Implications for public health: Many Aboriginal children continue to face significant adversity. More sustainable, Aboriginal-led programs are needed to augment positive family dynamics, identify at-risk children and provide safeguards during periods of familial adversity.

Health professional and community perspectives on reducing barriers to accessing specialist health care in metropolitan Aboriginal communities: A semi-structured interview study.

AIM: To describe the perspectives of health professionals and communities on an innovative health service delivery project, Hearing EAr health and Language Services (HEALS). HEALS was a government funded initiative to improve access to specialist ear, nose and throat and speech pathology services for Aboriginal families living in metropolitan areas. METHODS: Semi-structured interviews were conducted with 21 health-care professionals (clinicians, health service managers and Aboriginal health workers) and 16 care givers of children who participated in HEALS. Interviews took place at four Aboriginal Community Controlled Health Services in metropolitan Australia or by telephone. Interview transcripts were analysed thematically. RESULTS: We identified five major themes: leveraging partnerships (building on collaborative research, integrating and expanding existing networks, engaging the Aboriginal community), intrinsic and extrinsic motivation (seizing opportunities for altruism, empowered by collegiality, taking pride in achievements), removing common barriers (circumventing waiting times and cost, providing culturally appropriate services, raising awareness), strategic service delivery (proactive service delivery, encouraging flexibility and innovation, offering convenience and support), and service shortfall (pressured timeframes, desire for more sustainable services). CONCLUSION: HEALS facilitated improved health-care access by providing prompt, no-cost services that were strategically targeted to address multiple barriers. HEALS' model of care was built upon strong pre-existing research partnerships, the knowledge and support of five Aboriginal Community Controlled Health Services, and the willingness and motivation of local health-care professionals to help Close the Gap. HEALS highlights the importance of tailoring health services to the needs of Aboriginal families, and provides a framework for other health service delivery initiatives.

A case study of enhanced clinical care enabled by Aboriginal health research: the Hearing, EAr health and Language Services (HEALS) project.

OBJECTIVE: To describe and evaluate Hearing EAr health and Language Services (HEALS), a New South Wales (NSW) health initiative implemented in 2013 and 2014 as a model for enhanced clinical services arising from Aboriginal health research. METHODS: A case-study involving a mixed-methods evaluation of the origins and outcomes of HEALS, a collaboration among five NSW Aboriginal Community Controlled Health Services (ACCHS), the Sydney Children's Hospitals Network, NSW Health, the Aboriginal Health and Medical Research Council, and local service providers. Service delivery data was collected fortnightly; semi-structured interviews were conducted with healthcare providers and caregivers of children who participated in HEALS. RESULTS: To circumvent health service barriers, HEALS used relationships established through the Study of Environment on Aboriginal Resilience and Child Health (SEARCH) to form a specialist healthcare network. HEALS employed dedicated staff and provided a Memorandum of Understanding (detailing mutual goals and responsibilities) for each ACCHS. Despite very tight timeframes, HEALS provided services for 653 Aboriginal children, including 5,822 speech-language pathology sessions and 219 Ear, Nose and Throat procedures. Four themes reflecting the perceived impact of HEALS were identified: valued clinical outcomes, raising community awareness, developing relationships/networks and augmented service delivery. CONCLUSIONS: HEALS delivered rapid and effective specialist healthcare services through an existing research collaboration with five ACCHS, cooperation from local health service providers, and effective community engagement. Implications for Public Health: HEALS serves as a framework for targeted, enhanced healthcare that benefits Aboriginal communities by encapsulating the 'no research without service' philosophy.

"There's a housing crisis going on in Sydney for Aboriginal people": focus group accounts of housing and perceived associations with health.

BACKGROUND: Poor housing is widely cited as an important determinant of the poor health status of Aboriginal Australians, as for indigenous peoples in other wealthy nations with histories of colonisation such as Canada, the United States of America and New Zealand. While the majority of Aboriginal Australians live in urban areas, most research into housing and its relationship with health has been conducted with those living in remote communities. This study explores the views of Aboriginal people living in Western Sydney about their housing circumstances and what relationships, if any, they perceive between housing and health. METHODS: Four focus groups were conducted with clients and staff of an Aboriginal community-controlled health service in Western Sydney (n = 38). Inductive, thematic analysis was conducted using framework data management methods in NVivo10. RESULTS: Five high-level themes were derived: the battle to access housing; secondary homelessness; overcrowding; poor dwelling conditions; and housing as a key determinant of health. Participants associated their challenging housing experiences with poor physical health and poor social and emotional wellbeing. Housing issues were said to affect people differently across the life course; participants expressed particular concern that poor housing was harming the health and developmental trajectories of many urban Aboriginal children. CONCLUSIONS: Housing was perceived as a pivotal determinant of health and wellbeing that either facilitates or hinders prospects for full and healthy lives. Many of the specific health concerns participants attributed to poor housing echo existing epidemiological research findings. These findings suggest that housing may be a key intervention point for improving the health of urban Aboriginal Australians.

Building better research partnerships by understanding how Aboriginal health communities perceive and use data: a semistructured interview study.

OBJECTIVE: To describe the attitudes and beliefs of health professionals working in Aboriginal Community Controlled Health Services (ACCHS) towards the access, usage and potential value of routinely obtained clinical and research data. DESIGN, SETTING AND PARTICIPANTS: Face-to-face, semistructured interviews were conducted with 35 health professionals from 2 urban and 1 regional ACCHS in New South Wales. The interviews were transcribed and themes were identified using an adapted grounded theory approach. RESULTS: Six major themes were identified: occupational engagement (day-to-day relevance, contingent on professional capacity, emphasising clinical relevance), trust and assurance (protecting ownership, confidence in narratives, valuing local sources), motivation and empowerment (engaging the community, influencing morale, reassuring and encouraging clients), building research capacity (using cultural knowledge, promoting research aptitude, prioritising specific data), optimising service provision (necessity for sustainable services, guiding and improving services, supporting best practice), and enhancing usability (ensuring ease of comprehension, improving efficiency of data management, valuing accuracy and accessibility). CONCLUSIONS: Participants were willing to learn data handling procedures that could further enhance health service delivery and enable more ACCHS-led research, but busy workloads restrict these opportunities. Staff held concerns regarding the translation of research data into beneficial services, and believed that the outcome and purpose of data collection could be communicated more clearly. Promoting research partnerships, ensuring greater awareness of positive health data and the purposes of data collection, and communicating data in a user-friendly format are likely to encourage greater data use, build research capacity and improve health services within the Aboriginal community.

Measuring the quality of public open space using Google Earth.

BACKGROUND: Proximity to public open space, such as parks and other green spaces, has considerable health benefits, and people have been shown to be more likely to use such space for physical activity if it is of high quality. This paper describes a new remote-assessment approach that makes use of Google Earth Pro (the free version of this program is Google Earth) to provide rapid and inexpensive measurement of the quality of public open space. PURPOSE: The aim of the study was to assess the correlation between assessments of the quality of public open space using (1) the remote method (making use of Google Earth Pro) and (2) direct observation with a well-established measure of quality, the Public Open Space Tool (POST). METHODS: Fifty parks selected from the southwest part of Sydney, Australia, were assessed in 2009 with the remote method (using Google Earth Pro), and scores were compared with those obtained from direct observation of the same parks using POST. The time taken to conduct the assessments using each method was also recorded. Raters for each method were blind to scores obtained from using the other method. Analyses were conducted in 2009. RESULTS: The Spearman correlation coefficient between the quality scores obtained for the 50 parks using the remote method and direct observation was 0.9 (p<0.0001). The remote method took 4 hours, whereas direct observation took 42 hours, showing the remote method to be much faster and more resource efficient for the measurement of the quality of physical activity-related environments. CONCLUSIONS: The remote-assessment method provides, for the first time, the capacity to assess the quality of large numbers of parks and other green spaces without the need for in-person visits, dramatically reducing the time required for environmental audits of public open space.

Ion chromatographic determination of trace hydroxylamine in waste streams generated by a pharmaceutical reaction process.

Hydroxylamine is a key raw material used in a synthetic drug process at Pharmacia. Since hydroxylamine is harmful to microorganisms, concentrations above 5 ppm could interfere with the biological sewage plant performance. This necessitated the development of a sensitive analytical method for detecting low levels of hydroxylamine in the waste streams generated from the pharmaceutical process. The present report describes a cation-exchange chromatographic method coupled with pulsed amperometric detection at a gold electrode for trace analysis of hydroxylamine. This method was evaluated by generating data on the parameters of specificity, precision, linearity, recovery and sensitivity.
