The Marri Gudjaga project: a study protocol for a randomised control trial using Aboriginal peer support workers to promote breastfeeding of Aboriginal babies.

BACKGROUND: Breastfeeding protects against a range of conditions in the infant, including sudden infant death syndrome (SIDS), diarrhoea, respiratory infections and middle ear infections [1, 2]. The World Health Organization (WHO) recommends exclusive breastfeeding until six months of age, with continued breastfeeding recommended for at least two years and other complementary nutritious foods [3]. The 2017-18 National Health Survey (NHS) and 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) reported that the proportion of breastfeeding in Aboriginal and Torres Strait Islander infants (0-2 years) were less than half that of non-Indigenous infants (21.2% vs. 45%, respectively)[4]. There is a lack of research on interventions supporting Aboriginal women to breastfeed, identifying an evaluation gap related to peer support interventions to encourage exclusive breastfeeding in Aboriginal women. METHODS: We will evaluate the effect of scheduled breastfeeding peer support for and by Aboriginal women, on breastfeeding initiation and the prevalence of exclusive breastfeeding. This MRFF (Medical Research Future Fund) funded project is designed as a single-blinded cluster randomised controlled trial recruiting six sites across New South Wales, Australia, with three sites being randomised to employ a peer support worker or undertaking standard care. Forty pregnant women will be recruited each year from each of the six sites and will be surveyed during pregnancy, at six weeks, four and six months postnatally with a single text message at 12 months to ascertain breastfeeding rates. In-depth interviews via an Indigenous style of conversation and storytelling called 'Yarning' will be completed at pre- and post-intervention with five randomly recruited community members and five health professionals at each site" [5]. Yarns will be audio recorded, transcribed, coded and thematic analysis undertaken. Health economic analysis will be completed to assess the health system incremental cost and effects of the breastfeeding intervention relative to usual care. DISCUSSION: Evidence will be given on the effectiveness of Aboriginal peer support workers to promote the initiation and continuation of breastfeeding of Aboriginal babies. The findings of this study will provide evidence of effectiveness and cost-effectiveness of including peer support workers in postnatal care to promote breastfeeding practices.

Accuracy of reporting of Aboriginality on administrative health data collections using linked data in NSW, Australia.

BACKGROUND: Aboriginal people are under-reported on administrative health data in Australia. Various approaches have been used or proposed to improve reporting of Aboriginal people using linked records. This cross-sectional study used self-reported Aboriginality from the NSW Patient Survey Program (PSP) as a reference standard to assess the accuracy of reporting of Aboriginal people on NSW Admitted Patient (APDC) and Emergency Department Data Collections (EDDC), and compare the accuracy of selected approaches to enhance reporting Aboriginality using linked data. METHODS: Ten PSP surveys were linked to five administrative health data collections, including APDC, EDDC, perinatal, and birth and death registration records. Accuracy of reporting of Aboriginality was assessed using sensitivity, specificity, and positive and negative predictive values (PPVs and NPVs) and F score for the EDDC and APDC as baseline and four enhancement approaches using linked records: "Most recent linked record", "Ever reported as Aboriginal", and two approaches using a weight of evidence, "Enhanced Reporting of Aboriginality (ERA) algorithm" and "Multi-stage median (MSM)". RESULTS: There was substantial under-reporting of Aboriginality on APDC and EDDC records (sensitivities 84 and 77% respectively) with PPVs of 95% on both data collections. Overall, specificities and NPVs were above 98%. Of people who were reported as Aboriginal on the PSP, 16% were not reported as Aboriginal on any of their linked records. Record linkage approaches generally increased sensitivity, accompanied by decrease in PPV with little change in overall F score for the APDC and an increase in F score for the EDDC. The "ERA algorithm" and "MSM" approaches provided the best overall accuracy. CONCLUSIONS: Weight of evidence approaches are preferred when record linkage is used to improve reporting of Aboriginality on administrative health data collections. However, as a substantial number of Aboriginal people are not reported as Aboriginal on any of their linked records, improvements in reporting are incomplete and should be taken into account when interpreting results of any analyses. Enhancement of reporting of Aboriginality using record linkage should not replace efforts to improve recording of Aboriginal people at the point of data collection and addressing barriers to self-identification for Aboriginal people.

Eclampsia in Australia and New Zealand: A prospective population-based study.

BACKGROUND: Eclampsia is a serious consequence of pre-eclampsia. There are limited data from Australia and New Zealand (ANZ) on eclampsia. AIM: To determine the incidence, management and perinatal outcomes of women with eclampsia in ANZ. MATERIALS AND METHODS: A two-year population-based descriptive study, using the Australasian Maternity Outcomes Surveillance System (AMOSS), carried out in 263 sites in Australia, and all 24 New Zealand maternity units, during a staggered implementation over 2010-2011. Eclampsia was defined as one or more seizures during pregnancy or postpartum (up to 14 days) in any woman with clinical evidence of pre-eclampsia. RESULTS: Of 136 women with eclampsia, 111 (83%) were in Australia and 25 (17%) in New Zealand. The estimated incidence of eclampsia was 2.2 (95% confidence interval (CI) 1.9-2.7) per 10 000 women giving birth. Aboriginal and Torres Strait Islander women were over-represented in Australia (n = 9; 8.1%). Women with antepartum eclampsia (n = 58, 42.6%) were more likely to have a preterm birth (P = 0.04). Sixty-three (47.4%) women had pre-eclampsia diagnosed prior to their first eclamptic seizure of whom 19 (30.2%) received magnesium sulphate prior to the first seizure. Nearly all women (n = 128; 95.5%) received magnesium sulphate post-seizure. No woman received prophylactic aspirin during pregnancy. Five women had a cerebrovascular haemorrhage, and there were five known perinatal deaths. CONCLUSIONS: Eclampsia is an uncommon consequence of pre-eclampsia in ANZ. There is scope to reduce the incidence of this condition, associated with often catastrophic morbidity, through the use of low-dose aspirin and magnesium sulphate in women at higher risk.

The iBobbly Aboriginal and Torres Strait Islander app project: Study protocol for a randomised controlled trial.

BACKGROUND: Suicide amongst Australian Aboriginal and Torres Strait Islander communities occurs at twice the rate of the general population and, with significant barriers to treatment, help-seeking prior to a suicide attempt is low. This trial aims to test the effectiveness of an app (iBobbly) designed with Aboriginal and Torres Strait Islander people for reducing suicidal ideation. METHODS/DESIGN: This is a two-arm randomised controlled trial that will compare iBobbly to a wait-list control condition. The trial aims to recruit Aboriginal and Torres Strait Islander participants aged 16 years and over to test iBobbly, which is a self-help app delivering content based on acceptance and commitment therapy. The primary outcome for the study is suicidal ideation, and secondary outcomes include depression, hopelessness, distress tolerance, perceived burdensomeness and thwarted belonging, and help-seeking intentions. Data will be collected for both groups at baseline, post-intervention (after 6 weeks of app use), and at 6 months post-baseline (with a final 12-month follow-up for the iBobbly group). Primary analysis will compare changes in suicidal ideation for the intervention condition relative to the wait-list control condition using mixed models. An examination of the cost-effectiveness of the intervention compared to the control condition will be conducted. DISCUSSION: If effective, iBobbly could overcome many barriers to help-seeking amongst a group of people who are at increased risk of suicide. It may provide a low-cost, accessible intervention that can reach more people. This trial will add to a sparse literature on indigenous suicide prevention and will increase our knowledge about the effectiveness of e-health interventions for suicide prevention.

Learning about Aboriginal health and wellbeing at the postgraduate level: novel application of the Growth and Empowerment Measure.

INTRODUCTION: Public health education strives to transform and empower students to engage in policy and practice improvement. However, little is known of the nature of such change among students, especially when studying Aboriginal health and wellbeing, which may involve disrupting long held assumptions and prejudices. This article reports findings regarding the feasibility, specificity and sensitivity of the Growth and Empowerment Measure (GEM) in the evaluation of two innovative Australian 13-week postgraduate public health electives focused on Aboriginal health and wellbeing. The GEM's 14-item Emotional Empowerment Scale (EES14) and its subscales Inner Peace and Self-Capacity, and 12 Scenarios (S12) and its subscales Healing and Growth and Connection and Purpose were used to examine transformative experiences. A new short form of the S12, the Core6, was also trialled as a briefer measure of functional empowerment. METHODS: Pre-course GEM responses and demographic information were collected from consenting students during the mandatory, face-to-face workshops of the Aboriginal public health Perspectives course and the Aboriginal empowerment and wellbeing Lifespan course. The two-day Perspectives course workshop introduced a group scenario-building activity towards ending health inequality. Lifespan students experienced a 3-day immersion based on Stage 1 of the Aboriginal Family Well Being empowerment program. Insights from both workshops were further integrated through structured online discussions and written assessments. At the end of semester, a post-course GEM was mailed to students for completion and return. Students could also provide feedback through evaluation surveys and semi-structured focus groups. Effect sizes were assessed using paired t-tests, Wilcoxon signed-rank tests and multiple ANOVA. Cronbach's alpha confirmed internal consistency. RESULTS: Baseline GEM data was provided for 147 out of a total of 194 workshop experiences from participating students. Twenty students attended workshops for both Perspectives and Lifespan. Fifty-five matched pairs (representing 52 individual participants) were obtained from 170 students who completed one or both courses. Statistically significant positive change of small to medium effect size was detected in all GEM scales, subscales and some individual items. Lifespan yielded larger effects than Perspectives, most markedly on two subscales: Inner Peace, and Connection and Purpose. Participating students reported significant growth in the Scenario item 'knowing and being who I am' following Perspectives and Lifespan. Those completing Perspectives also reported a significant increase in 'gaining voice and being heard', consistent with its action-oriented scenario-building assessment. In contrast, the psychosocial development approach embedded in Lifespan stimulated strong development in spirituality, responding constructively to judgement, appreciating empowerment in their communities and skills to make changes in their lives. Feedback indicated that students valued these personal and professional growth experiences. CONCLUSION: The GEM was sensitive and specific in measuring components of empowering change among participants. Challenges included low post-course response rates that limited extrapolation to overall course impact, and attention needed to starting point when comparing the increment of change. The GEM is a promising tool for studying postgraduate courses designed to stimulate transformative learning, wellbeing and cultural competence through empowerment, and relevant in the education of health professionals in the fields of Aboriginal and rural health.

The effectiveness of a sustained nurse home visiting intervention for Aboriginal infants compared with non-Aboriginal infants and with Aboriginal infants receiving usual child health care: a quasi-experimental trial - the Bulundidi Gudaga study.

BACKGROUND: In Australia there is commitment to developing interventions that will 'Close the Gap' between the health and welfare of Indigenous and non-Indigenous Australians and recognition that early childhood interventions offer the greatest potential for long term change. Nurse led sustained home visiting programs are considered an effective way to deliver a health and parenting service, however there is little international or Australian evidence that demonstrates the effectiveness of these programs for Aboriginal infants. This protocol describes the Bulundidi Gudaga Study, a quasi-experimental design, comparing three cohorts of families from the Macarthur region in south western Sydney to explore the effectiveness of the Maternal Early Childhood Sustained Home-visiting (MECSH) program for Aboriginal families. METHODS: Mothers were recruited when booking into the local hospital for perinatal care and families are followed up until child is age 4 years. Participants are from three distinct cohorts: Aboriginal MECSH intervention cohort (Group A), Non-Aboriginal MECSH intervention cohort (Group B) and Aboriginal non-intervention cohort (Group C). Eligible mothers were those identified as at risk during the Safe Start assessment conducted by antenatal clinic midwives. Mothers in Group A were eligible if they were pregnant with an Aboriginal infant. Mothers in Group B were eligible if they were pregnant with a non-Aboriginal infant. Mothers in Group C are part of the Gudaga descriptive cohort study and were recruited between October 2005 and May 2007. The difference in duration of breastfeeding, child body mass index, and child development outcomes at 18 months and 4 years of age will be measured as primary outcomes. We will also evaluate the intervention effect on secondary measures including: child dental health; the way the program is received; patterns of child health and illness; patterns of maternal health, health knowledge and behaviours; family and environmental conditions; and service usage for mothers and families. DISCUSSION: Involving local Aboriginal research and intervention staff and investing in established relationships between the research team and the local Aboriginal community is enabling this study to generate evidence regarding the effectiveness of interventions that are feasible to implement and sustainable in the context of Aboriginal communities and local service systems.

Rheumatic heart disease in pregnancy: strategies and lessons learnt implementing a population-based study in Australia.

Background: The global burden of rheumatic heart disease (RHD) is two-to-four times higher in women, with a heightened risk in pregnancy. In Australia, RHD is found predominantly among Aboriginal and Torres Strait Islander peoples. Methods: This paper reviews processes developed to identify pregnant Australian women with RHD during a 2-year population-based study using the Australasian Maternity Outcomes Surveillance System (AMOSS). It evaluates strategies developed to enhance reporting and discusses implications for patient care and public health. Results: AMOSS maternity coordinators across 262 Australian sites reported cases. An extended network across cardiac, Aboriginal and primary healthcare strengthened surveillance and awareness. The network notified 495 potential cases, of which 192 were confirmed. Seventy-eight per cent were Aboriginal and/or Torres Strait Islander women, with a prevalence of 22 per 1000 in the Northern Territory. Discussion: Effective surveillance was challenged by a lack of diagnostic certainty, incompatible health information systems and varying clinical awareness among health professionals. Optimal outcomes for pregnant women with RHD demand timely diagnosis and access to collaborative care. Conclusion: The strategies employed by this study highlight gaps in reporting processes and the opportunity pregnancy provides for diagnosis and re/engagement with health services to support better continuity of care and promote improved outcomes.

Rheumatic heart disease in pregnancy: How can health services adapt to the needs of Indigenous women? A qualitative study.

OBJECTIVES: To study rheumatic heart disease health literacy and its impact on pregnancy, and to identify how health services could more effectively meet the needs of pregnant women with rheumatic heart disease. MATERIALS AND METHODS: Researchers observed and interviewed a small number of Aboriginal women and their families during pregnancy, childbirth and postpartum as they interacted with the health system. An Aboriginal Yarning method of relationship building over time, participant observations and interviews with Aboriginal women were used in the study. The settings were urban, island and remote communities across the Northern Territory. Women were followed interstate if they were transferred during pregnancy. The participants were pregnant women and their families. We relied on participants' abilities to tell their own experiences so that researchers could interpret their understanding and perspective of rheumatic heart disease. RESULTS: Aboriginal women and their families rarely had rheumatic heart disease explained appropriately by health staff and therefore lacked understanding of the severity of their illness and its implications for childbearing. Health directives in written and spoken English with assumed biomedical knowledge were confusing and of limited use when delivered without interpreters or culturally appropriate health supports. CONCLUSIONS: Despite previous studies documenting poor communication and culturally inadequate care, health systems did not meet the needs of pregnant Aboriginal women with rheumatic heart disease. Language-appropriate health education that promotes a shared understanding should be relevant to the gender, life-stage and social context of women with rheumatic heart disease.

What factors contribute to the continued low rates of Indigenous status identification in urban general practice? - A mixed-methods multiple site case study.

BACKGROUND: Indigenous peoples experience worse health and die at younger ages than their non-indigenous counterparts. Ethnicity data enables health services to identify inequalities experienced by minority populations and to implement and monitor services specifically targeting them. Despite significant Government intervention, Australia's Indigenous peoples, the Aboriginal and Torres Strait Islander peoples, continue to be under identified in data sets. We explored the barriers to Indigenous status identification in urban general practice in two areas in Sydney. METHODS: A mixed-methods multiple-site case study was used, set in urban general practice. Data collection included semi-structured interviews and self-complete questionnaires with 31 general practice staff and practitioners, interviews with three Medicare Local staff, and focus groups with the two local Aboriginal and Torres Strait Islander communities in the study areas. These data were combined with clinical record audit data and Aboriginal unannounced standardised patient visits to participating practices to determine the current barriers to Indigenous status identification in urban general practice. RESULTS: Findings can be broadly grouped into three themes: a lack of practitioner/staff understanding on the need to identify Indigenous status or that a problem with identification exists; suboptimal practice systems to identify and/or record patients' Indigenous status; and practice environments that do not promote Indigenous status identification. CONCLUSION: Aboriginal and Torres Strait Islander peoples remain under-identified in general practice. There is a need to address the lack of practitioner and staff recognition that a problem with Indigenous status identification exists, along with entrenched attitudes and beliefs and limitations to practice software capabilities. Guidelines recommending Indigenous status identification and Aboriginal and Torres Strait Islander-specific Practice Incentive Payments have had limited impact on Indigenous status identification rates. It is likely that policy change mandating Indigenous status identification and recording in general practice will also be required.

Equity in disease prevention: Vaccines for the older adults - a national workshop, Australia 2014.

On the 20th June, 2014 the National Health and Medical Research Council's Centre for Research Excellence in Population Health "Immunisation in under Studied and Special Risk Populations", in collaboration with the Public Health Association of Australia, hosted a workshop "Equity in disease prevention: vaccines for the older adults". The workshop featured international and national speakers on ageing and vaccinology. The workshop was attended by health service providers, stakeholders in immunisation, ageing, primary care, researchers, government and non-government organisations, community representatives, and advocacy groups. The aims of the workshop were to: provide an update on the latest evidence around immunisation for the older adults; address barriers for prevention of infection in the older adults; and identify immunisation needs of these groups and provide recommendations to inform policy. There is a gap in immunisation coverage of funded vaccines between adults and infants. The workshop reviewed provider misconceptions, lack of Randomised Control Trials (RCT) and cost-effectiveness data in the frail elderly, loss of autonomy, value judgements and ageism in health care and the need for an adult vaccination register. Workshop recommendations included recognising the right of elderly people to prevention, the need for promotion in the community and amongst healthcare workers of the high burden of vaccine preventable diseases and the need to achieve high levels of vaccination coverage, in older adults and in health workers involved in their care. Research into new vaccine strategies for older adults which address poor coverage, provider attitudes and immunosenescence is a priority. A well designed national register for tracking vaccinations in older adults is a vital and basic requirement for a successful adult immunisation program. Eliminating financial barriers, by addressing inequities in the mechanisms for funding and subsidising vaccines for the older adults compared to those for children, is important to improve equity of access and vaccination coverage. Vaccination coverage rates should be included in quality indicators of care in residential aged care for older adults. Vaccination is key to healthy ageing, and there is a need to focus on reducing the immunisation gap between adults and children.

The uptake of Aboriginal and Torres Strait Islander health assessments fails to improve in some areas.

BACKGROUND: The Medicare-rebated Health Assessment for Aboriginal and Torres Strait Islander People (Medicare Benefits Schedule [MBS] item number 715) has been progressively implemented across Australia since 1999. OBJECTIVE: This paper explores some of the reasons why the uptake of Health Assessment for Aboriginal and Torres Strait Islander People remains low in some metropolitan general practices. METHODS: Semi-structured interviews and self-complete mail surveys with 31 general practice staff and practitioners were combined with an audit of practice systems and patient medical records in seven general practices in Sydney. RESULTS: Barriers to MBS item number 715 uptake included low rates of Indigenous status identification, lack of knowledge of MBS item numbers, lack of organisational teamwork within the practice and avoidance of billing specific MBS item numbers. DISCUSSION: The low uptake of MBS item number 715 in some metropolitan areas is of particular concern given the known gaps in Aboriginal and Torres Strait Islander health. Targeted action is required to address the barriers to uptake and re-evaluate the use of MBS item number 715 as a key performance indicator.

The value of partnerships: lessons from a multi-site evaluation of a national social and emotional wellbeing program for Indigenous youth.

OBJECTIVE: To evaluate the first three years of a national program to improve the social and emotional wellbeing of Indigenous youth in remote and regional Australia. METHODS: Combination of open inquiry and audit review involving investigation of process and outcomes, with a broad national overview supplemented by five in-depth case studies in diverse settings. RESULTS: Community development principles were applied at all 14 sites. There were many examples of collaborative, community-driven health promotion initiatives, with most progress observed where there were strong local partnerships. Within the range of activities, education sessions on alcohol and other drugs, mental health and violence were facilitated by program staff. There was a tension between community development and specific program delivery, with the balance reflecting the needs and capacity of individual sites, program staff expertise and contractual requirements. CONCLUSIONS AND IMPLICATIONS: The main lessons concern program design and resourcing and ways of working. Program staff at each site learned to be not too ambitious, but to work consistently with the community, establishing partnerships and engaging and training community members. Community and stakeholder capacity enhancement should be regarded as core, and evaluation built in. Activities directed at youth must be engaging and effective, and integrated with other programs and services.

Maternal super-obesity and perinatal outcomes in Australia: a national population-based cohort study.

BACKGROUND: Super-obesity is associated with significantly elevated rates of obstetric complications, adverse perinatal outcomes and interventions. The purpose of this study was to determine the prevalence, risk factors, management and perinatal outcomes of super-obese women giving birth in Australia. METHODS: A national population-based cohort study. Super-obese pregnant women (body mass index (BMI) >50 kg/m(2) or weight >140 kg) who gave birth between January 1 and October 31, 2010 and a comparison cohort were identified using the Australasian Maternity Outcomes Surveillance System (AMOSS). Outcomes included maternal and perinatal morbidity and mortality. Prevalence estimates calculated with 95% confidence intervals (CIs). Adjusted odds ratios (ORs) were calculated using multivariable logistic regression. RESULTS: 370 super-obese women with a median BMI of 52.8 kg/m(2) (range 40.9-79.9 kg/m(2)) and prevalence of 2.1 per 1 000 women giving birth (95% CI: 1.96-2.40). Super-obese women were significantly more likely to be public patients (96.2%), smoke (23.8%) and be socio-economically disadvantaged (36.2%). Compared with other women, super-obese women had a significantly higher risk for obstetric (adjusted odds ratio (AOR) 2.42, 95% CI: 1.77-3.29) and medical (AOR: 2.89, 95% CI: 2.64-4.11) complications during pregnancy, birth by caesarean section (51.6%) and admission to special care (HDU/ICU) (6.2%). The 372 babies born to 365 super-obese women with outcomes known had significantly higher rates of birthweight ≥ 4500 g (AOR 19.94, 95 % CI: 6.81-58.36), hospital transfer (AOR 3.81, 95 % CI: 1.93-7.55) and admission to Neonatal Intensive Care Unit (NICU) (AOR 1.83, 95% CI: 1.27-2.65) compared to babies of the comparison group, but not prematurity (10.5% versus 9.2%) or perinatal mortality (11.0 (95% CI: 4.3-28.0) versus 6.6 (95% CI: 2.6- 16.8) per 1 000 singleton births). CONCLUSIONS: Super-obesity in pregnancy in Australia is associated with increased rates of pregnancy and birth complications, and with social disadvantage. There is an urgent need to further address risk factors leading to super-obesity among pregnant women and for maternity services to better address pre-pregnancy and pregnancy care to reduce associated inequalities in perinatal outcomes.

Experiences and views of a brokerage model for primary care for Aboriginal people.

OBJECTIVE: A mixed methods study was conducted to determine the views of Aboriginal people on their experiences of a brokerage model for access to community-based health services in an urban setting. METHODS: A broad range of approaches, using surveys, semi-structured interviews and community forums with Aboriginal people were used to find out people's views and experiences of using the brokerage service. RESULTS: Of the 1304 people invited to participate, only 127 people provided feedback on the brokerage service model for Aboriginal people. Of these, 120 people identified as being Aboriginal. Participants said that the service helped them to navigate the system and access health care. Participants felt that the health professionals involved with the service were respectful of their needs. The service was not able to improve access to dental care. CONCLUSIONS: The brokerage model implemented in this area appears to have been well received and is supporting urban Aboriginal people to access some of the health care needed.

The Koori Growing Old Well Study: investigating aging and dementia in urban Aboriginal Australians.

BACKGROUND: Dementia is an emerging health priority in Australian Aboriginal communities, but substantial gaps remain in our understanding of this issue, particularly for the large urban section of the population. In remote Aboriginal communities, high prevalence rates of dementia at relatively young ages have been reported. The current study is investigating aging, cognitive decline, and dementia in older urban/regional Aboriginal Australians. METHODS: We partnered with five Aboriginal communities across the eastern Australian state of New South Wales, to undertake a census of all Aboriginal men and women aged 60 years and over residing in these communities. This was followed by a survey of the health, well-being, and life history of all consenting participants. Participants were also screened using three cognitive instruments. Those scoring below designated cut-offs, and a 20% random sample of those scoring above (i.e. "normal" range), completed a contact person interview (with a nominated family member) and medical assessment (blind to initial screening results), which formed the basis of "gold standard" clinical consensus determinations of cognitive impairment and dementia. CONCLUSION: This paper details our protocol for a population-based study in collaboration with local Aboriginal community organizations. The study will provide the first available prevalence rates for dementia and cognitive impairment in a representative sample of urban Aboriginal people, across city and rural communities, where the majority of Aboriginal Australians live. It will also contribute to improved assessment of dementia and cognitive impairment and to the understanding of social determinants of successful aging, of international significance.

Immunisation coverage among a birth cohort of Aboriginal infants in an urban community.

AIM: The aim of this study is to examine the age-appropriate immunisation coverage and the factors associated with this in a cohort of Aboriginal infants in an outer urban Sydney community in comparison with non-Aboriginal infants in this community. METHODS: Data on immunisation coverage were extracted from the Australian Childhood Immunisation Register for a birth cohort of 178 Aboriginal and 356 non-Aboriginal infants born in Campbelltown between October 2005 and May 2007. Non-Aboriginal infants were matched on birthdates and gender. Data on maternal socio-economic and other characteristics were collected by questionnaire. RESULTS: Australian Childhood Immunisation Register records were identified for 92% of infants. Immunisation rates of Aboriginal infants were comparable with those of non-Aboriginal infants except for delay at 4 and 6 months. Rates of delay in immunisation at 12 and 18 months for both Aboriginal and non-Aboriginal infants were similar. Young maternal age and higher parity were both associated with a greater likelihood of delay. CONCLUSIONS: Immunisation rates in this population of Aboriginal infants are comparable to those of non-Aboriginal infants except for delay in immunisation at 4 and 6 months. Identified risk factors for both Aboriginal and non-Aboriginal infants may be amenable to intervention. Strategies to ensure timely compliance with immunisation schedules in this outer urban community have achieved reasonable immunisation coverage for Aboriginal and non-Aboriginal infants.

Validation and enhancement of Australian Aboriginal and Torres Strait Islander psychiatric hospitalisation statistics through an Indigenous Mental Health Worker Register.

INTRODUCTION: Inaccuracy in identification of Indigenous status on health records hampers collection of the good quality data required to guide policies, programs and services. This study examined the use of an Indigenous Mental Health Worker Register to assess the level of correct identification of Indigenous status and sources of error among psychiatric admissions within a regional public hospital information system. METHOD: The study was conducted in 2004/2005 and 2005/2006 at the Cairns Base Hospital Mental Health Unit, Queensland, Australia, serving a population of 230,000 of which 13.2% identify as Aboriginal and/or Torres Strait Islander. Psychiatric admissions data, including Indigenous status, accessed from the hospital-based corporate information system (HBCIS) were compared with data collected through an Indigenous Mental Health Worker Register that is maintained through extensive networking. Investigation of mismatches enabled estimation of the frequency and sources of incorrect identification of Indigenous status and the impact of this on hospital statistics. RESULTS: Cross-validation of HBCIS data with the Indigenous Register over 2 years revealed 355 Indigenous admissions. Of the total 355 admissions, 301 (84.8%) were correctly identified and included in the hospital system, while 22 (6.2%) were designated non-Indigenous, 13 (3.7%) were 'unspecified' and 19 (5.4%) were missed through incorrect residence or admission designation. Among 1293 non-Indigenous admissions, 1.1% were incorrectly identified as Indigenous, while 25.5% of the 51 with unspecified status were found to be Indigenous. Furthermore, 45 Indigenous separations that had been missed over the previous 5 year period (1999/2000 to 2003/2004) were identified through careful examination of all those with unspecified status (n=174) and those with multiple separations of mixed designation of Indigenous status (n=15); all of the latter 15 were confirmed Indigenous by other mental health database and/or the Indigenous Mental Health Worker. Thus overall this study revealed a total of 89 Indigenous separations and 1261 occupied bed days in the 7 year period that had not be identified in the hospital information system. CONCLUSION: A novel method was used to ascertain the reliability of Indigenous status identification among mental health admissions within a hospital information system in a region with relatively high Indigenous population representation. This revealed that 85% of admissions were correctly identified over two consecutive years. Perhaps more importantly, the study confirmed a low frequency of false identification of non-Indigenous people as Aboriginal and/or Torres Strait Islander. The work has also demonstrated the value of involving Indigenous Mental Health Workers in routine processes to enhance, validate and improve Indigenous statistics and increase access to culturally informed care.

The Australasian Maternity Outcomes Surveillance System: an evaluation of stakeholder engagement, usefulness, simplicity, acceptability, data quality and stability.

BACKGROUND: The Australasian Maternity Outcomes Surveillance System (AMOSS) conducts active, prospective surveillance of severe maternal conditions in Australia and New Zealand (ANZ). AMOSS captures greater than 96% of all births, and utilises an online, active case-based negative reporting system. AIM: To evaluate AMOSS using the United States Centres for Disease Control (MMWR 2001; 50 (RR13): 1-35.) surveillance system evaluation framework. METHODS: Data were gathered using multiple methods, including an anonymous online survey administered to 353 AMOSS data collectors, in addition to review of case data received during 2009-2011, documented records of project board and advisory group meeting minutes, publications, annual reports and the AMOSS database. RESULTS: AMOSS is a research system characterised by its simplicity and efficiency. The socio-demographic, risk factor and severe morbidity clinical data collected on rare conditions are not duplicated in other routine data systems. AMOSS is functioning well and has sustained buy-in from clinicians, stakeholders and consumers and a high level of acceptability to data collectors in ANZ maternity units. CONCLUSIONS: AMOSS is the only existing national system of surveillance for rare and severe maternal conditions in ANZ and therefore serves an important function, utilising data collected from reliable sources, in an effective, efficient and timely way.

Under-reporting of birth registrations in New South Wales, Australia.

BACKGROUND: To determine the rates of birth registration over a five-year period in New South Wales (NSW) and explore the factors associated with the rate of registration. METHODS: This is a cross-sectional study using linked population databases. The study population included all births of NSW residents in NSW between 2001 and 2005. RESULTS: Birth registration rates in NSW were 82.66% in the year of birth, 93.19% in the first year, 94.02% in the second, 94.56% in the third and 95.08% in the fourth year after birth. The non-registration of births was mainly associated with such factors as neonatal and postneonatal death (adjusted OR = 3.84, 95% CI: 3.23-4.57); being Indigenous (adjusted OR = 3.26, 95% CI: 3.10-3.43); maternal age <25 or >39 years (adjusted OR = 2.81, 95% CI: 2.72-2.90); low birthweight (<2,500 grams) (adjusted OR = 1.79, 95% CI: 1.69-1.90); living in remote areas (adjusted OR = 1.57, 95% CI: 1.52-1.63); being born after the first quarter of year (adjusted OR = 1.08-1.56, 95% CI between 1.03-1.12 and 1.49-1.64); mother having more pregnancies (adjusted OR = 1.85-7.29, 95% CI between1.78-1.93 and 6.87-7.73). Mothers who were born overseas were more likely to register their births than those born in Australia (adjusted OR = 0.72, 95% CI: 0.69-0.75). Multiple births were more likely to be registered than singleton births (adjusted OR = 0.84, 95% CI: 0.76-0.92). About one-third of the non-registrations of births in NSW were explained by the risk factors. The reasons for the remaining non-registrations need to be investigated. CONCLUSION: Of birth in NSW, 4.92% were not registered by the fourth year after birth.
