Quantitative evaluation of an outreach case management model of care for urban Aboriginal and Torres Strait Islander adults living with complex chronic disease: a longitudinal study.

BACKGROUND: Chronic diseases are the leading contributor to the excess morbidity and mortality burden experienced by Aboriginal and Torres Strait Islander (hereafter, respectfully, Indigenous) people, compared to their non-Indigenous counterparts. The Home-based Outreach case Management of chronic disease Exploratory (HOME) Study provided person-centred, multidisciplinary care for Indigenous people with chronic disease. This model of care, aligned to Indigenous peoples' conceptions of health and wellbeing, was integrated within an urban Indigenous primary health care service. We aimed to determine the impact of this model of care on participants' health and wellbeing at 12 months. METHODS: HOME Study participants were Indigenous, regular patients of the primary health care service, with a diagnosis of at least one chronic disease, and complex health and social care needs. Data were collected directly from participants and from their medical records at baseline, and 3, 6 and 12 months thereafter. Variables included self-rated health status, depression, utilisation of health services, and key clinical outcomes. Participants' baseline characteristics were described using frequencies and percentages. Generalized estimating equation (GEE) models were employed to evaluate participant attrition and changes in outcome measures over time. RESULTS: 60 participants were enrolled into the study and 37 (62%) completed the 12-month assessment. After receiving outreach case management for 12 months, 73% of participants had good, very good or excellent self-rated health status compared with 33% at baseline (p < 0.001) and 19% of participants had depression compared with 44% at baseline (p = 0.03). Significant increases in appointments with allied health professionals (p < 0.001) and medical specialists other than general practitioners (p = 0.001) were observed at 12-months compared with baseline rates. Mean systolic blood pressure decreased over time (p = 0.02), but there were no significant changes in mean HbA1c, body mass index, or diastolic blood pressure. CONCLUSIONS: The HOME Study model of care was predicated on a holistic conception of health and aimed to address participants' health and social care needs. The positive changes in self-rated health and rates of depression evinced that this aim was met, and that participants received the necessary care to support and improve their health and wellbeing.

Investigating the feasibility, acceptability and appropriateness of outreach case management in an urban Aboriginal and Torres Strait Islander primary health care service: a mixed methods exploratory study.

BACKGROUND: The disparities in health and life expectancy of Aboriginal and Torres Strait Islander peoples compared to non-Indigenous Australians are well documented. Chronic diseases are a leading contributor to these disparities. We aimed to determine the feasibility, acceptability and appropriateness of a case management approach to chronic disease care integrated within an urban Aboriginal and Torres Strait Islander primary health care service. METHODS: The Home-based, Outreach case Management of chronic disease Exploratory (HOME) Study provided holistic, patient centred multidisciplinary care for Aboriginal and Torres Strait Islander people with chronic disease. A developmental evaluation approach supported the implementation and ongoing adaptations in the delivery of the model of care, and ensured its alignment with Aboriginal and Torres Strait Islander peoples' understandings of, and approaches to, health and wellbeing. In-depth, semi-structured interviews were conducted with nine patient participants (one interview also included a participant's spouse) and 15 health service staff and key themes were identified through an iterative reflective process. Quantitative data were collected directly from patient participants and from their medical records at baseline, 3 and 6 months. Patient participants' baseline characteristics were described using frequencies and percentages. Attrition and patterns of missing values over time were evaluated using binomial generalized estimating equation (GEE) models and mean differences in key clinical outcomes were determined using normal GEE models. RESULTS: Forty-one patients were recruited and nine withdrew over the 6 month period. There was no evidence of differential attrition. All participants (patients and health service staff) were very positive about the model of care. Patient participants became more involved in their health care, depression rates significantly decreased (p = 0.03), and significant improvements in systolic blood pressure (p < 0.001) and diabetes control (p = 0.05) were achieved. CONCLUSIONS: The exploratory nature of our study preclude any definitive statements about the effectiveness of our model of care. However, staff and patients' high levels of satisfaction and improvements in the health and wellbeing of patients are promising and suggest its feasibility, acceptability and appropriateness. Further research is required to determine its efficacy, effectiveness and cost-effectiveness in improving the quality of life and quality of care for Aboriginal and Torres Strait Islander peoples living with chronic disease.

Facilitators and barriers to implementation of a pragmatic clinical trial in Aboriginal health services.

OBJECTIVE: To identify facilitators and barriers to clinical trial implementation in Aboriginal health services. DESIGN: Indepth interview study with thematic analysis. SETTING: Six Aboriginal community-controlled health services and one government-run service involved in the Kanyini Guidelines Adherence with the Polypill (KGAP) study, a pragmatic randomised controlled trial that aimed to improve adherence to indicated drug treatments for people at high risk of cardiovascular disease. PARTICIPANTS: 32 health care providers and 21 Aboriginal and Torres Strait Islander patients. RESULTS: A fundamental enabler was that participants considered the research to be governed and endorsed by the local health service. That the research was perceived to address a health priority for communities was also highly motivating for both providers and patients. Enlisting the support of Aboriginal and Torres Strait Islander staff champions who were visible to the community as the main source of information about the trial was particularly important. The major implementation barrier for staff was balancing their service delivery roles with adherence to often highly demanding trial-related procedures. This was partially alleviated by the research team's provision of onsite support and attempts to make trial processes more streamlined. Although more intensive support was highly desired, there were usually insufficient resources to provide this. CONCLUSION: Despite strong community and health service support, major investments in time and resources are needed to ensure successful implementation and minimal disruption to already overstretched, routine services. Trial budgets will necessarily be inflated as a result. Funding agencies need to consider these additional resource demands when supporting trials of a similar nature.

Household number associated with middle ear disease at an urban Indigenous health service: a cross-sectional study.

Few epidemiological studies of middle ear disease have been conducted in Aboriginal and Torres Strait Islander populations, yet the disease is common and causes hearing impairment and poorer educational outcomes. The objective of this study is to identify factors associated with abnormal middle ear appearance, a proxy for middle ear disease. Aboriginal and Torres Strait Islander children aged 0-14 years receiving a Child Health Check (CHC) at an urban Indigenous Health Service, Brisbane, Australia were recruited from 2007 to 2010. Mixed-effects models were used to explore associations of 10 recognised risk factors with abnormal middle ear appearance at the time of the CHC. Ethical approval and community support for the project were obtained. Four hundred and fifty-three children were included and 54% were male. Participants were Aboriginal (92%), Torres Strait Islander (2%) or both (6%). Abnormal middle ear appearance was observed in 26 (6%) children and was significantly associated with previous ear infection (odds ratio (OR), 8.8; 95% confidence interval (CI), 3.2-24.0) and households with eight or more people (OR, 3.8; 95% CI, 1.1-14.1) in the imputed multivariable mixed-effects model. No significant associations were found for the other recognised risk factors investigated. Overcrowding should continue to be a core focus for communities and policy makers in reducing middle ear disease and its consequences in Aboriginal and Torres Strait Islander peoples.

Implementing computerised Aboriginal and Torres Strait Islander health checks in primary care for clinical care and research: a process evaluation.

BACKGROUND: Paper-based Aboriginal and Torres Strait Islander health checks have promoted a preventive approach to primary care and provided data to support research at the Inala Indigenous Health Service, south-west Brisbane, Australia. Concerns about the limitations of paper-based health checks prompted us to change to a computerised system to realise potential benefits for clinical services and research capability. We describe the rationale, implementation and anticipated benefits of computerised Aboriginal and Torres Strait Islander health checks in one primary health care setting. METHODS: In May 2010, the Inala Indigenous Health Service commenced a project to computerise Aboriginal and Torres Strait Islander child, adult, diabetic, and antenatal health checks. The computerised health checks were launched in September 2010 and then evaluated for staff satisfaction, research consent rate and uptake. Ethical approval for health check data to be used for research purposes was granted in December 2010. RESULTS: Three months after the September 2010 launch date, all but two health checks (378 out of 380, 99.5%) had been completed using the computerised system. Staff gave the system a median mark of 8 out of 10 (range 5-9), where 10 represented the highest level of overall satisfaction. By September 2011, 1099 child and adult health checks, 138 annual diabetic checks and 52 of the newly introduced antenatal checks had been completed. These numbers of computerised health checks are greater than for the previous year (2010) of paper-based health checks with a risk difference of 0.07 (95% confidence interval 0.05, 0.10). Additionally, two research projects based on computerised health check data were underway. CONCLUSIONS: The Inala Indigenous Health Service has demonstrated that moving from paper-based Aboriginal and Torres Strait Islander health checks to a system using computerised health checks is feasible and can facilitate research. We expect computerised health checks will improve clinical care and continue to enable research projects using validated data, reflecting the local Aboriginal and Torres Strait Islander community's priorities.

Factors Associated with Thoughts of Self-Harm or Suicide among Aboriginal and Torres Strait Islander People Presenting to Urban Primary Care: An Analysis of De-Identified Clinical Data.

Suicide amongst Aboriginal and Torres Strait Islander people is a major cause of premature mortality and a significant contributor to the health and life expectancy gap. This study aimed to estimate the prevalence of thoughts of self-harm or suicide in Aboriginal and Torres Strait Islander people attending an urban primary health care service and identify factors associated with these thoughts. Multilevel mixed-effects modified Poisson regression models were employed to analyse three years of data gathered during the annual Aboriginal and Torres Strait Islander health assessments. At their first health assessment, 11.5% (191/1664) of people reported thoughts of suicide or self-harm in the prior two weeks. Having children, participating in sport or community activities or being employed full-time decreased the risk of such thoughts. Conversely, factors relating to social exclusion including homelessness, drug use, unemployment and job insecurity increased the risk of thoughts of self-harm or suicide. Individual clinicians, health services, and policy-makers all have a role in suicide prevention. Clinicians need appropriate training to be able to respond to people expressing these thoughts. Aboriginal and Torres Strait Islander community organisations need sovereignty and self-determination over resources to provide programs that promote cultural connectivity and address social exclusion, thereby saving lives.

Knowing our patients: a cross-sectional study of adult patients attending an urban Aboriginal and Torres Strait Islander primary healthcare service.

Many Aboriginal and Torres Strait Islander people live in urban areas, but epidemiological data about their health status and health needs are lacking. This knowledge is critical to informing and evaluating initiatives to improve service delivery and health outcomes. One potential data source is de-identified routinely collected clinical data. This cross-sectional study, conducted in an urban Aboriginal and Torres Strait Islander primary healthcare service, involved randomly selecting a sample of 400 patients aged ≥15 years, and manually extracting electronic health record data. In the sample, 49% of patients were aged <35 years, 56% were female and 38% were employed. Overall, 56% of females and 47% of males aged 35-54 years had depression, 26% had experienced a bereavement within the last 12 months, and while 44% were alcohol abstainers, 35% were drinking at high-risk levels. The present study cannot demonstrate causal relationships between the observed high rates of chronic disease in older people and frequent experiences of bereavement and high levels of mental ill health in young- and middle-aged adults. However, a life course approach provides a framework to understand the interconnectedness of these results, and suggests that strategies to blunt the intergenerational burden of chronic disease need to address the social and emotional wellbeing of youth.

Retinal photography for diabetic retinopathy screening in Indigenous primary health care: the Inala experience.

OBJECTIVE: We aimed to determine the impact of clinic based retinal photography on access to appropriate screening for diabetic retinopathy (DR). DESIGN, SETTING AND PARTICIPANTS: We opportunistically recruited patients undergoing their annual diabetic cycle of care over a two year period in the urban Indigenous primary health care clinic. Data were collected on retinal outcomes, health variables and referral patterns. MAIN OUTCOME MEASURES: Access to appropriate screening and ophthalmic follow up, prevalence of DR, acceptability and feasibility of clinic-based retinal photography were the main outcome measures of this study. RESULTS: One hundred and thirty-two of a possible 147 patients consented to participate. 30% of participants had DR. Appropriate screening and ophthalmic follow up increased six fold, from 20 to 124 participants, following the introduction of the retinal camera. Most participants felt very positive about DR screening. CONCLUSIONS: Primary care DR screening using retinal photography can improve access to DR screening for indigenous patients, reduce the burden on busy outpatient departments and should reduce visual loss. Policy-makers could contribute to screening sustainability by funding a medicare item-number for primary care based DR screening associated with the annual diabetic cycle of care. An upfront Practice Incentive Program (PIP) payment could offset set up costs.

Adult health checks for Indigenous Australians: the first year's experience from the Inala Indigenous Health Service.

OBJECTIVE: To evaluate the role of the adult health check for Aboriginal and Torres Strait Islander people aged 15-54 years, in an urban Indigenous primary health care setting. DESIGN, SETTING AND PARTICIPANTS: Cross-sectional study of Indigenous patients recruited opportunistically from the Inala Indigenous Health Service between 1 June 2007 and 31 July 2008. MAIN OUTCOME MEASURES: Newly identified cardiovascular risk factors, investigations ordered and performed, interventions and new diagnoses made. RESULTS: 413 patients out of a possible 509 consented to participate (93% were Aboriginal). High prevalences of cardiovascular risk factors such as smoking (67%), being overweight and obese (61%), harmful levels of alcohol consumption (36%), and depression (23%) were found. The adult health checks resulted in new investigations (in 82% of participants), lifestyle advice (67%), vaccinations (42%), referrals (62%) and new medications (49%). New diagnoses resulting from the health checks included depression (6%), a harmful level of alcohol consumption (4%), chlamydia infection (4%), hypertension (3%) and diabetes (3%). Pap smears were performed in 47% of women as a result of the health check. CONCLUSIONS: The adult health check for Aboriginal and Torres Strait Islanders aged 15-54 years is a viable vehicle for evaluating health status, identifying chronic disease risk factors and for implementing preventive health care.

Improving Indigenous patients' access to mainstream health services: the Inala experience.

In 1994, only 12 Indigenous people attended the mainstream general practice in Inala, south-western Brisbane, Queensland. An Indigenous community focus group and telephone interviews revealed deficits such as: few items (eg, artwork) that Indigenous people could identify with; lack of Indigenous staff; staff perceived as unfriendly; inflexibility regarding time; and intolerance of Indigenous children's behaviour. Access to the Inala Indigenous Health Service by Indigenous people improved when these issues were addressed, and has grown significantly every year from 1995 to 2008. Other important factors in improving access include: energetic Indigenous leadership; enabling bulk billing to increase funding; moving to a stand-alone clinic; and engaging with teaching, research and community programs. A Centre of Excellence in Indigenous Primary Health Care is envisaged as the next innovation required to improve access and quality of service, and to close the gap between Indigenous and non-Indigenous health outcomes.

Cardiovascular disease risk management for Aboriginal and Torres Strait Islander peoples in primary health care settings: findings from the Kanyini Audit.

OBJECTIVE: To describe cardiovascular disease (CVD) risk management in Indigenous primary health care. DESIGN, SETTING AND PARTICIPANTS: Review of 1165 randomly selected case records of Indigenous Australian adults, aged >/= 18 years, regularly attending eight health services in diverse settings in New South Wales, Queensland and Central Australia, October 2007 - May 2008. MAIN OUTCOME MEASURE: Adherence to CVD risk screening and management guidelines, especially with respect to overall or absolute CVD risk. RESULTS: More than half the people in the sample (53%) were not adequately screened for CVD risk according to national recommendations. Underscreening was significantly associated with younger age, less frequent attendance, and lower uptake of the Medicare Health Assessment. Of the sample, 9% had established CVD, and 29% of those aged >/= 30 years were classified as high risk according to the 2004 National Heart Foundation of Australia (NHFA) adjusted Framingham equation. Of those with CVD, 40% (95% CI, 30%-50%) were not prescribed a combination of blood pressure (BP) medicines, statins and antiplatelet agents, and 56% (95% CI, 49%-62%) of high-risk individuals without CVD were not prescribed BP medicines and statins. For high-risk individuals not prescribed BP medicines or statins, 74% (95% CI, 64%-84%) and 30% (95% CI, 23%-39%) respectively, did not meet 2004 NHFA criteria for prescribing of these medications, and of those already prescribed BP medicines or statins, 41% (95% CI, 36%-47%) and 59% (95% CI, 52%-66%) did not meet respective guideline targets. CONCLUSIONS: These management gaps are similar to those found in non-Indigenous health care settings, suggesting deficiencies across the health system. Prescribing guidelines which exclude many high-risk individuals contribute to suboptimal management. Guideline reform and improved health service capacity could substantially improve Indigenous vascular health.
