Administration of Burns First Aid Treatment to Aboriginal and Torres Strait Islander children in community settings.

OBJECTIVE: This paper investigates Burn First Aid Treatment (BFAT) provided to Aboriginal and Torres Strait Islander children in Australia at the scene of injury using data from a population-based cohort study. STUDY DESIGN: The participants were 208 Aboriginal and Torres Strait Islander children aged < 16 years who sustained a burns injury between 2015-2018, and their carers. The primary outcome measure was gold standard BFAT, (defined as at least 20 min of cool, running water within 3 h of the injury); additional measures included type of first aid, length of first aid provided, and carer's knowledge of first aid. RESULTS: Of the 208 caregivers, 168 provided open-ended responses that indicated first aid was applied to their child; however, only 34 received gold standard BFAT at the scene of the injury, 110 did not receive correct BFAT, and 24 were unsure what first aid was applied. CONCLUSION: This study highlights an important need for communities to have access to appropriate evidence-based and co-designed BFAT education and training.

Understanding burn injury among Aboriginal and Torres Strait Islander children - results of a two-year cohort study.

BACKGROUND: Despite known inequalities, little is understood about the burden and healthcare experiences of Aboriginal and Torres Strait Islander children who sustain a burn injury and their families. METHODS: The Coolamon Study recruited parents and carers whose children (aged <16 years) were Aboriginal and / or Torres Strait Islander children and had presented to burn units across four Australian states, New South Wales (Sydney), Northern Territory (Darwin), Queensland (Brisbane, Townsville) and South Australia (Adelaide), between 2015 and 2018. Consent was obtained and carers completed baseline and subsequent interviews at 3, 6, 12 and 24 months. Data were collected on the injury event, patient care and safety, sociodemographic factors, health related quality of life (PedsQual), and psychological distress (Kessler K-5). RESULTS: Of the 208 participants, 64 % were male; 26 % were aged less than 2 years and 37 % aged 2-4 years. The most common burn mechanisms were scalds (37 %), contact (33 %) and flame burns (21 %), with more severe burns and flame burns occurring in rural and remote settings. Most carers rated their child's care as either excellent or very good (82 %). Family distress, measured by the K-5, lessened over the 24 months, however the changes were not statistically significant. While 77 % of carers reported that they received enough information, 18 % reported they would have liked more, and 3 % reported no information was provided before treatment. Parents described mixed access to information about the types of support available to them, such as accommodation, meals, travel or cultural support. CONCLUSION: Data from this cohort provide rich new information about risk factors and care received from point of injury through to rehabilitation for Aboriginal and Torres Strait Islander children with burns, providing unique insights into what is needed for appropriate, culturally safe care.

Hospitalisations and in-hospital deaths following moderate to severe traumatic brain injury in Australia, 2015-20: a registry data analysis for the Australian Traumatic Brain Injury National Data (ATBIND) project.

OBJECTIVE: To describe the frequency of hospitalisation and in-hospital death following moderate to severe traumatic brain injury (TBI) in Australia, both overall and by patient demographic characteristics and the nature and severity of the injury. DESIGN, SETTING: Cross-sectional study; analysis of Australia New Zealand Trauma Registry data. PARTICIPANTS: People with moderate to severe TBI (Abbreviated Injury Score [head] greater than 2) who were admitted to or died in one of the twenty-three major Australian trauma services that contributed data to the ATR throughout the study period, 1 July 2015 - 30 June 2020. MAJOR OUTCOME MEASURES: Primary outcome: number of hospitalisations with moderate to severe TBI; secondary outcome: number of deaths in hospital following moderate to severe TBI. RESULTS: During 2015-20, 16 350 people were hospitalised with moderate to severe TBI (mean, 3270 per year), of whom 2437 died in hospital (14.9%; mean, 487 per year). The mean age at admission was 50.5 years (standard deviation [SD], 26.1 years), and 11 644 patients were male (71.2%); the mean age of people who died in hospital was 60.4 years (SD, 25.2 years), and 1686 deaths were of male patients (69.2%). The overall number of hospitalisations did not change during 2015-20 (per year: incidence rate ratio [IRR], 1.00; 95% confidence interval [CI], 0.99-1.02) and death (IRR, 1.00; 95% CI, 0.97-1.03). CONCLUSION: Injury prevention and trauma care interventions for people with moderate to severe TBI in Australia reduced neither the incidence of the condition nor the associated in-hospital mortality during 2015-20. More effective care strategies are required to reduce the burden of TBI, particularly among younger men.

Discharge interventions for First Nations people with a chronic condition or injury: a systematic review.

BACKGROUND: Aboriginal and Torres Strait Islander peoples have a unique place in Australia as the original inhabitants of the land. Similar to other First Nations people globally, they experience a disproportionate burden of injury and chronic health conditions. Discharge planning ensures ongoing care to avoid complications and achieve better health outcomes. Analysing discharge interventions that have been implemented and evaluated globally for First Nations people with an injury or chronic conditions can inform the implementation of strategies to ensure optimal ongoing care for Aboriginal and Torres Strait Islander people. METHODS: A systematic review was conducted to analyse discharge interventions conducted globally among First Nations people who sustained an injury or suffered from a chronic condition. We included documents published in English between January 2010 and July 2022. We followed the reporting guidelines and criteria set in Preferred Reporting Items for Systematic Review (PRISMA). Two independent reviewers screened the articles and extracted data from eligible papers. A quality appraisal of the studies was conducted using the Mixed Methods Appraisal Tool and the CONSIDER statement. RESULTS: Four quantitative and one qualitative study out of 4504 records met inclusion criteria. Three studies used interventions involving trained health professionals coordinating follow-up appointments, linkage with community care services and patient training. One study used 48-hour post discharge telephone follow-up and the other text messages with prompts to attend check-ups. The studies that included health professional coordination of follow-up, linkage with community care and patient education resulted in decreased readmissions, emergency presentations, hospital length of stay and unattended appointments. CONCLUSION: Further research on the field is needed to inform the design and delivery of effective programs to ensure quality health aftercare for First Nations people. We observed that discharge interventions in line with the principal domains of First Nations models of care including First Nations health workforce, accessible health services, holistic care, and self-determination were associated with better health outcomes. REGISTRATION: This study was prospectively registered in PROSPERO (ID CRD42021254718).

Codesigning informative resources for families of Aboriginal and Torres Strait Islander children who sustained a burn injury: a protocol for a participatory action research study.

INTRODUCTION: Parents of children hospitalised in a burn unit experience psychological trauma and later post-traumatic stress. Aboriginal and Torres Strait Islander families whose child has been admitted to a burn unit encounter additional burdens through a culturally unsafe healthcare system. Psychosocial interventions can help reduce anxiety, distress and trauma among children and parents. There remains a lack of interventions or resources that reflect Aboriginal and Torres Strait Islander people's perspective of health. The objective of this study is to codevelop a culturally appropriate informative resource to assist Aboriginal and Torres Strait Islander parents whose child has been hospitalised in a burn unit. METHODS: In this participatory research study, the development of a culturally safe resource will build on Aboriginal and Torres Strait Islander families' experiences and voices, complemented by the knowledge and expertise of an Aboriginal Health Worker (AHW) and burn care experts. Data will be collected through recorded yarning sessions with families whose child has been admitted to a burn unit, the AHW and burn care experts. Audiotapes will be transcribed and data will be analysed thematically. Analysis of yarning sessions and resource development will follow a cyclical approach. ETHICS AND DISSEMINATION: This study has been approved by the Aboriginal Health and Medical Research Council (AH&MRC) (1690/20) and the Sydney Children's Hospitals Network ethics committee (2020/ETH02103). Findings will be reported to all participants and will be disseminated with the broader community, the funding body and health workers at the hospital. Dissemination with the academic community will be through peer-reviewed publications and presentations in relevant conferences.

Major traumatic pedestrian injury in Australia: Characteristics and in-hospital outcomes from the Australia New Zealand Trauma Registry.

BACKGROUND: The leading global cause of death for people aged 5-29 years is road traffic injury, a quarter of which is borne by pedestrians. The epidemiology of major hospitalised pedestrian injury across Australia is not reported. This study aims to address this gap using data from the Australia New Zealand Trauma Registry. METHODS: The registry hosts information on patients admitted to 25 major trauma centres across Australia who sustain a major injury (ISS > 12) or die following injury. Patients were included if they were injured due to pedestrian injury from 1st July 2015-30 th June 2019. Analysis included patient and injury characteristics, injury patterns and in-hospital outcomes. Primary endpoints included risk-adjusted mortality and length of stay. RESULTS: There were 2159 injured pedestrians; of these, 327 died. Young adults (20-25 years) were the largest group, especially on weekends. Older adults (70 + years) were the largest cohort in pedestrian deaths. The most common injuries were head (42.2 %). One-third of patients were intubated prior to or on ED arrival (n = 731, 34.3 %). CONCLUSION: Emergency clinicians should have a high index for severe pedestrian injury. Further reduction in road speed in residential areas could reduce all-age pedestrian injury in Australia.

Can smoking cause impotence? a radiological retrospective cohort study comparing internal pudendal artery calcification on CT in male smokers versus non-smokers.

BACKGROUND AND AIMS: This retrospective cohort study evaluated the degree of pelvic inflow and internal pudendal artery (IPA) calcification in male smokers versus non-smokers. As erectile dysfunction (ED) is strongly associated with IPA vascular, we wanted to investigate radiologically if there was a statistically significant difference in the degree of IPA calcification in smokers and potentially be a contributing factor in the cause of ED. METHODS: CT studies of 100 men aged between 40 and 60 years of age were blindly reviewed and assigned a calcium score of their vascular calcification levels. We compared scores of 50 smokers versus 50 non-smokers. The Mann Whitney U test statistic was used to test for a statistical difference in calcification score between the smoking and non-smoking groups. RESULTS: Results show a statistically significant association between smoking and pelvic inflow and IPA calcification. The Mann Whitney U test demonstrated a statistically significant higher calcium score in the smoking group (mean = 4.8, SD 3.7), versus the non-smoking group, (mean = 1.8, SD 1.9) (U = 701.5, p < 0.05). CONCLUSIONS: This research is the first of its kind based on an extensive literature review. The association between vascular calcification and smoking is well established, in addition to the direct relationship of IPA calcification and ED. This unique study has demonstrated an increased rate of IPA calcification in smokers with a potential inferred association with ED. Findings represent a novel and useful deterrent for health authorities to include in anti-smoking campaigns.

Patient journey mapping to investigate quality and cultural safety in burn care for Aboriginal and Torres Strait Islander children and families - development, application and implications.

BACKGROUND: Quality and safety in Australian healthcare is inequitably distributed, highlighted by gaps in the provision of quality care for Aboriginal and Torres Strait Islander children. Burns have potential for long-term adverse outcomes, and quality care, including culturally safe care, is critical to recovery. This study aimed to develop and apply an Aboriginal Patient Journey Mapping (APJM) tool to investigate the quality of healthcare systems for burn care with Aboriginal and Torres Strait Islander children. STUDY DESIGN: Interface research methodology, using biomedical and cultural evidence, informed the modification of an existing APJM tool. The tool was then applied to the journey of one family accessing a paediatric tertiary burn care site. Data were collected through yarning with the family, case note review and clinician interviews. Data were analysed using Emden's core story and thematic analysis methods. Reflexivity informed consideration of the implications of the APJM tool, including its effectiveness and efficiency in eliciting information about quality and cultural safety. RESULTS: Through application of a modified APJM tool, gaps in quality care for Aboriginal and Torres Strait Islander children and families were identified at the individual, service and system levels. Engagement in innovative methodology incorporating more than biomedical standards of care, uncovered critical information about the experiences of culturally safe care in complex patient journeys. CONCLUSION: Based on our application of the tool, APJM can identify and evaluate specific aspects of culturally safe care as experienced by Aboriginal and Torres Strait Islander peoples and be used for quality improvement.

Optimal timing of SPECT/CT to demonstrate parathyroid adenomas in 99mTc-sestamibi scintigraphy.

BACKGROUND: Accurate preoperative localisation of the parathyroid adenoma is essential to achieve a minimally invasive parathyroidectomy. The purpose of this study was to validate and improve our single-isotope dual-phase parathyroid imaging protocol utilising 99mTechnetium-Sestamibi ([99mTc]MIBI). There has been no accepted gold standard evidence-based protocol regarding timing of single-photon emission computed tomography/computed tomography (SPECT/CT) acquisition in parathyroid imaging with resultant variation between centres. We sought to determine the optimum timing of SPECT/CT post administration of [99mTc]MIBI in the identification of parathyroid adenomas. We aimed to evaluate the efficacy of early and late SPECT/CT and to establish whether SPECT/CT demonstrates increased sensitivity over planar imaging. MATERIAL AND METHODS: A sample of 36 patients with primary hyperparathyroidism underwent planar and SPECT/CT acquisition 15 minutes (early) and two hours (late) post [99mTc]MIBI administration. Two radionuclide radiologists reviewed the images and Fisher's exact Chi-squared statistic was used to evaluate the diagnostic performances of early versus late SPECT/CT acquisition and SPECT/CT versus planar imaging. RESULTS: Twenty-one likely parathyroid adenomas were identified with a statistically superior diagnosis rate in the late SPECT/CT acquisition compared with both early SPECT/CT and planar imaging (p < 0.05). All adenomas diagnosed on early SPECT/CT acquisition were also identified on late SPECT/CT images. CONCLUSIONS: Single late phase SPECT/CT is significantly superior to early SPECT/CT in the identification of parathyroid adenomas. Late SPECT/CT improves diagnostic accuracy over planar acquisition. Imaging protocols should be revised to include late SPECT/CT acquisition. Early SPECT/CT acquisition can be eliminated from scan protocols with associated implications regarding reduced scan time and increased patient throughput.

Discharge Interventions for First Nations People with Injury or Chronic Conditions: A Protocol for a Systematic Review.

Severe injury and chronic conditions require long-term management by multidisciplinary teams. Appropriate discharge planning ensures ongoing care to mitigate the long-term impact of injuries and chronic conditions. However, First Nations peoples in Australia face ongoing barriers to aftercare. This systematic review will locate and analyse global evidence of discharge interventions that have been implemented to improve aftercare and enhance health outcomes among First Nations people with an injury or chronic condition. A systematic search will be conducted using five databases, Google, and Google scholar. Global studies published in English will be included. We will analyse aftercare interventions implemented and the health outcomes associated. Two independent reviewers will screen and select studies and then extract and analyse the data. Quality appraisal of the included studies will be conducted using the Mixed Methods Appraisal Tool and the CONSIDER statement. The proposed study will analyse global evidence on discharge interventions that have been implemented for First Nations people with an injury or chronic conditions and their associated health outcomes. Our findings will guide healthcare quality improvement to ensure Aboriginal and Torres Strait Islander peoples have ongoing access to culturally safe aftercare services.

The Australian Traumatic Brain Injury National Data (ATBIND) project: a mixed methods study protocol.

BACKGROUND: Traumatic brain injury (TBI) is the largest contributor to death and disability in people who have experienced physical trauma. There are no national data on outcomes for people with moderate to severe TBI in Australia. OBJECTIVES: To determine the incidence and key determinants of outcomes for patients with moderate to severe TBI, both for Australia and for selected population subgroups, including Aboriginal and Torres Strait Islander Australians. METHODS AND ANALYSIS: The Australian Traumatic Brain Injury National Data (ATBIND) project will analyse Australia New Zealand Trauma Registry (ATR) data and National Coronial Information Service (NCIS) deaths data. The ATR documents the demographic characteristics, injury event description and severity, processes of care, and outcomes for people with major injury, including TBI, assessed and managed at the 27 major trauma services in Australia. We will include data for people with moderate to severe TBI (Abbreviated Injury Scale [AIS] (head) score higher than 2) who had Injury Severity Scores [ISS] higher than 12 or who died in hospital. People will also be included if they died before reaching a major trauma service and the coronial report details were consistent with moderate to severe TBI. The primary research outcome will be survival to discharge. Secondary outcomes will be hospital discharge destination, hospital length of stay, ventilator-free days, and health service cost. ETHICS APPROVAL: The Alfred Ethics Committee approved ATR data extraction (project reference number 670/21). Further ethics approval has been sought from the NCIS and multiple Aboriginal health research ethics committees. The ATBIND project will conform with Indigenous data sovereignty principles. DISSEMINATION OF RESULTS: Our findings will be disseminated by project partners with the aim of informing improvements in equitable system-level care for all people in Australia with moderate to severe TBI. STUDY REGISTRATION: Not applicable.

Screening and social prescribing in healthcare and social services to address housing issues among children and families: a systematic review.

OBJECTIVES: Housing is a social determinant of health that impacts the health and well-being of children and families. Screening and referral to address social determinants of health in clinical and social service settings has been proposed to support families with housing problems. This study aims to identify housing screening questions asked of families in healthcare and social services, determine validated screening tools and extract information about recommendations for action after screening for housing issues. METHODS: The electronic databases MEDLINE, PsycINFO, EMBASE, Ovid Emcare, Scopus and CINAHL were searched from 2009 to 2021. Inclusion criteria were peer-reviewed literature that included questions about housing being asked of children or young people aged 0-18 years and their families accessing any healthcare or social service. We extracted data on the housing questions asked, source of housing questions, validity and descriptions of actions to address housing issues. RESULTS: Forty-nine peer-reviewed papers met the inclusion criteria. The housing questions in social screening tools vary widely. There are no standard housing-related questions that clinical and social service providers ask families. Fourteen screening tools were validated. An action was embedded as part of social screening activities in 27 of 42 studies. Actions for identified housing problems included provision of a community-based or clinic-based resource guide, and social prescribing included referral to a social worker, care coordinator or care navigation service, community health worker, social service agency, referral to a housing and child welfare demonstration project or provided intensive case management and wraparound services. CONCLUSION: This review provides a catalogue of housing questions that can be asked of families in the clinical and/or social service setting, and potential subsequent actions.

"No One Manages It; We Just Sign Them Up and Do It": A Whole System Analysis of Access to Healthcare in One Remote Australian Community.

OBJECTIVE: To assess the accessibility, availability and utilisation of a comprehensive range of community-based healthcare services for Aboriginal people and describe contributing factors to providing effective healthcare services from the provider perspective. SETTING: A remote community in New South Wales, Australia. PARTICIPANTS: Aboriginal and non-Aboriginal health and education professionals performing various roles in healthcare provision in the community. DESIGN: Case study. METHODOLOGY: The study was co-designed with the community. A mixed-methods methodology was utilised. Data were gathered through structured interviews. Descriptive statistics were used to analyse the availability of 40 health services in the community, whilst quotations from the qualitative research were used to provide context for the quantitative findings. RESULTS: Service availability was mapped for 40 primary, specialised, and allied health services. Three key themes emerged from the analysis: (1) there are instances of both underservicing and overservicing which give insight into systemic barriers to interagency cooperation; (2) nurses, community health workers, Aboriginal health workers, teachers, and administration staff have an invaluable role in healthcare and improving patient access to health services and could be better supported through further funding and opportunities for specialised training; and (3) visiting and telehealth services are critical components of the system that must be linked to existing community-led primary care services. CONCLUSION: The study identified factors influencing service availability, accessibility and interagency cooperation in remote healthcare services and systems that can be used to guide future service and system planning and resourcing.

Safely increasing nephro-ureteric stent exchange intervals, resulting in significant cost savings for the interventional radiology suite, a 2-year experience in a tertiary referral centre.

AIM: To evaluate the nephro-ureteric stent (NUS) insertion and exchange practice in a tertiary referral cancer centre, and determine the safety and compliance with current guidelines. We also reviewed if increasing exchange time interval from 6 to 12 weeks was safe, and if this could be adopted into our local guidelines. METHODS: A retrospective review was performed covering 24 months from January 2017 to December 2018. All NUS insertions and exchanges performed in that period were analysed, including the number of exchanges the patient underwent, the time between subsequent exchanges, and the screening time. We also reviewed the indications for stent insertion, possible causes for failed stent exchange, and factors which led to significant delays in stent exchanges for some patients. A scatterplot of screening time versus time in situ was derived and correlation analysis performed using the Pearson coefficient. RESULTS: Thirty-two patients underwent de novo NUS insertion during the period, and 102 NUS exchanges were performed. The interval between stent exchanges ranged from 1 to 40 weeks, with a mean of 12.3 weeks (SD = 8.96 weeks). Screening time ranged from 33 s to 17 min, with a mean of 3 min 50 s (SD = 3 min 35 s). There were 100 successful exchanges, and two failed exchanges, accounting for 1.9% of total exchanges. In both failed cases, the reason for failed exchange was due to a prolonged period between exchanges (6 months in both cases). The reason for delay for stent exchange was due to non-attendance for scheduled appointments. There was a weakly positive correlation coefficient of 0.06 (screening time versus time period between insertions); however, this was not statistically significant (p = 0.81). CONCLUSION: In this retrospective review, we have demonstrated that the recommended 6-week period between stent exchanges is unnecessary in the vast majority of cases, and that a longer interval between NUS exchanges, e.g. 8-12 weeks, is safe for the patient, and reduces screening time. This reduction in procedures also provides a significant potential saving to the radiology department in both monetary expense and limited angiography suite time.

The road beyond licensing: the impact of a driver licensing support program on employment outcomes for Aboriginal and Torres Strait Islander Australians.

BACKGROUND: With increasingly tough graduated driver licensing laws in all Australian States and Territories, driver licensing support programs are recognised as being important to support Aboriginal and Torres Strait Islander peoples to obtain a driver licence. Such programs appear to improve licensing attainment rates, but few studies have examined the broader impact that these programs can have. This research aims to 1) examine the impact of a New South Wales (NSW) based driver licensing support program (Driving Change) on client employment outcomes; 2) assess the influence of geographical area of program delivery on driver licence attainment. METHODS: Driving Change was delivered from February 2013 to August 2016 in 4 urban and 7 regional Aboriginal communities of NSW. Clients were followed-up at 6 months or more following contact with the program as part of routine program operations. Descriptive statistics and regression models were used to analyse data. RESULTS: From 933 clients contacted 254 agreed to provide feedback, a response rate of 27%. Those that responded were mostly female (57%), aged 24 years and under (72%), unemployed (85%) with secondary education or less (71%) and from a regional area (74%). Adjusted logistic regression indicated that clients who achieved an independent licence were more likely (OR: 2.5, 95% CI: 1.22-5.24, p = 0.011) of reporting a new job or change in job than those who did not attain a licence. Clients from regional areas were more likely (OR: 1.72, 95% CI: 1.27-2.33, p < 0.001) to gain an independent licence than those from urban areas. There was no difference in employment outcomes (OR: 1.2, 95% CI: 0.53-2.52, p = 0.719) for clients from urban compared to regional areas. CONCLUSION: The Driving Change program appears to be effective in improving employment outcomes for those who gained a licence. Clients from regional areas were more likely to gain a licence compared to those in urban settings, and were predominantly young and unemployed, often a hard to reach cohort. Future licensing programs being delivered in regional areas need integrated pathways into employment opportunities to provide holistic services that address the social and economic challenges faced by Aboriginal and Torres Strait Islander Australians.

Establishing determinants and quality indicators for getting home alive following moderate to severe traumatic brain injury: the Australian Traumatic Brain Injury National Data Project.

Moderate to severe traumatic brain injury (TBI) contributes to a significant burden across Australia. However, the data required to inform targeted equitable system-level improvements in emergency TBI care do not exist. The incidence and determinants of outcomes following moderate to severe TBI in Australia remain unknown. The variation in the impact of moderate to severe TBI, according to patient demographics and injury mechanism, is poorly defined. The Australian Traumatic Brain Injury National Data Project will lead to a clear understanding, across Australia and pre-specified subgroups (including Aboriginal and Torres Strait Islander peoples), of the incidence, determinants and impact of priority outcomes following moderate to severe TBI, including survival to discharge home. Furthermore, this project will establish a set of national clinical quality indicators for patients experiencing a moderate to severe TBI. The Australian Traumatic Brain Injury National Data Project will inform where to target emergency care system-wide improvements. Without baseline data, efforts are wasted.

Considering difference: clinician insights into providing equal and equitable burns care for Aboriginal and Torres Strait Islander children.

OBJECTIVE: To better understand issues driving quality in burn care related to equity of outcomes and equality of provision for Aboriginal and Torres Strait Islander children. METHODS: Seventy-six interviews with team members who provide care for Aboriginal and Torres Strait Islander children in six paediatric burn units across five Australian jurisdictions were completed. Interface research methodology within a qualitative design guided data collection and analysis. RESULTS: Three themes were identified: i) Burn team members who identify the requirement to meet the specific needs of Aboriginal and Torres Strait Islander children and deliver differential care; ii) Burn team members who believe in equal care, but deliver differential care based on the specific needs of Aboriginal and Torres Strait Islander children; and iii) Burn team members who see little need for provision of differential care for Aboriginal and Torres Strait Islander children and rather, value the provision of equal care for all. CONCLUSION: Burn team members conflate equitable and equal care, which has implications for the delivery of care for Aboriginal and Torres Strait Islander children. Equitable care is needed to address disparities in post-burn outcomes, and this requires clinicians, healthcare services and relevant system structures to work coherently and intentionally to reflect these needs. Implications for public health: Changes in health policy, the embedding of Aboriginal and Torres Strait Islander liaison officers in burn care teams and systems that prioritise critical reflexive practice are fundamental to improving care.

Developing economic measures for Aboriginal and Torres Strait Islander families on out-of-pocket healthcare expenditure.

Objective Out-of-pocket healthcare expenditure (OOPHE) has a significant impact on marginalised households. The purpose of this study was to modify a pre-existing OOPHE survey for Aboriginal and Torres Strait Islander households with children. Methods The OOPHE survey was derived through a scoping review, face and content validity, including judgement quantification with content experts. Exploratory factor analyses determined factor numbers for construct validity. Repeatability through test-retest processes and reliability was assessed through internal consistency. Results The OOPHE survey had 168 items and was piloted on 67 Aboriginal and Torres Strait Islander parents. Construct validity assessment generated a 62-item correlation matrix with a three-factor model. Across these factors, item loadings varied, 10 items with high correlations (>0.70) and 20 with low correlations (<0.40). OOPHE survey retest was conducted with 47 families, where 43 items reached slight to fair levels of agreement. Conclusion The low level of item loadings to factors in the OOPHE survey indicates interconnectedness across the three-factor model, and reliability results suggest systemic differences. Impeding factors may include cohort homogeneity and survey length. It is unknown how cultural and social nuances specific to Aboriginal and Torres Strait Islander households impacts on results. Further work is warranted. What is known about the topic? Out-of-pocket healthcare expenditure (OOPHE) are expenses not covered by universal taxpayer-funded health insurance. In elderly Australians or those with chronic conditions, OOPHE can cause substantial burden and financial hardship and, in the most extreme cases, induce bankruptcy. Despite higher hospital admissions and disease burden, little is known about how OOPHE impacts Aboriginal and Torres Strait Islander families. Additionally, in Australia, no OOPHE survey tools have been appropriately assessed; this includes for use with Aboriginal and Torres Strait Islander families. What does this paper add? This pilot study modified a pre-existing Australian OOPHE survey for use with Aboriginal and Torres Strait Islander households with children. Knowledge interface methodology was used to bring together Indigenous knowledges with quantitative survey methods. This was critical to ensuring Indigenous knowledges were central to the overall pilot study across item creation, participant focus, outcome contextualisation, interpretation, and resetting dominant norms. Outcomes have demonstrated pertinent points for future work in this area, such as the complexities in developing robust, culturally safe and specific surveys, which reach ideal psychometric levels of validity and reliability for Aboriginal and Torres Strait Islander communities. Certainly, it raises questions for current and future research using surveys in Aboriginal and Torres Strait Islander communities, which are generic and not purpose-built. What are the implications for practitioners? We recommend that OOPHE surveys should be developed with Aboriginal and Torres Strait Islander families from the outset, so they can include important contextual factors for Aboriginal and Torres Strait Islander households.
