Aboriginal community controlled health services: leading the way in primary care.

The national Closing the Gap framework commits to reducing persisting disadvantage in the health of Aboriginal and Torres Strait Islander people in Australia, with cross-government-sector initiatives and investment. Central to efforts to build healthier communities is the Aboriginal community controlled health service (ACCHS) sector; its focus on prevention, early intervention and comprehensive care has reduced barriers to access and unintentional racism, progressively improving individual health outcomes for Aboriginal people. There is now a broad range of primary health care data that provides a sound evidence base for comparing the health outcomes for Indigenous people in ACCHSs with the outcomes achieved through mainstream services, and these data show: models of comprehensive primary health care consistent with the patient-centred medical home model; coverage of the Aboriginal population higher than 60% outside major metropolitan centres; consistently improving performance in key performance on best-practice care indicators; and superior performance to mainstream general practice. ACCHSs play a significant role in training the medical workforce and employing Aboriginal people. ACCHSs have risen to the challenge of delivering best-practice care and there is a case for expanding ACCHSs into new areas. To achieve the best returns, the current mainstream Closing the Gap investment should be shifted to the community controlled health sector.

Strengthening the link between policy formulation and implementation of Indigenous health policy directions.

This study aimed to understand the problems within the Indigenous health policy process in Australia and how weaknesses in the process impact on policy implementation. Using semi-structured questions, 23 key stakeholders in the policy-making process were interviewed. Three main themes dominated; a need for increased Indigenous involvement in policy formulation at the senior Australian Government level, increased participation of Indigenous community-controlled health organisations in the policy-making process and, most importantly, ensuring that policies have the necessary resources for their implementation. The emergence of these specific themes demonstrated weaknesses in policy process from the formulation stage onward. Tackling these would, according to our informants, significantly enhance the effectiveness of the policy process and contribute to further improvement of the health of Indigenous Australians.

Our hearts and minds--what would it take for Australia to become the healthiest country in the world?

OBJECTIVE: To highlight recent reductions in mortality rates in Australia and identify conditions and population groups with the greatest potential for further reduction in mortality rates. DESIGN: International benchmarking and intranational comparisons of mortality rates were used to identify areas with the greatest potential for improvement. RESULTS: Latest data from Organisation for Economic Cooperation and Development (OECD) countries confirm that, while Japan's death rates remain the lowest in the world, Australia's are decreasing rapidly and we now rival Switzerland for second overall ranking. When the contributions of specific conditions are compared, the areas with the greatest potential for reductions are circulatory diseases (especially ischaemic heart disease); suicide; injury and violence; smoking-related conditions; and cancers amenable to prevention/early detection. Intranational comparisons show considerable scope for reduction in inequalities, especially those between Aboriginal and Torres Strait Islander peoples and other Australians, between males and females, and between low and high socioeconomic groups. These conditions and inequalities are highly interrelated, as differentials in health status are often mediated through broader societal inequalities. CONCLUSIONS: Australia should aim to become the country with the lowest mortality rate in the world. This could realistically be achieved by benchmarking performance nationally and internationally, applying current knowledge and available interventions, matching policies with funding, and implementing systemic national programs and activities to promote health and prevent "illth".

Diagnosis and management costs of suspicious skin lesions from a population-based melanoma screening programme.

BACKGROUND: Recently, massive increases in health-care costs for the diagnosis and management of skin lesions have been observed (2000-05). The aim of this study was to describe the health system costs attributed to the diagnosis and management of suspicious skin lesions detected during a trial of a population melanoma screening programme (1998-2001). SETTING: Queensland, Australia. METHODS: Data from the trial and Medicare Australia were used to categorize and cost all suspicious skin lesions arising from the trial, which included general practitioner consultations, diagnosis/management and pathology. Comparisons were made with other screened and unscreened populations. RESULTS: Overall, 2982 lesions were treated within the trial producing a mean cost of Aus$118 per lesion. Excisions for benign lesions contributed the greatest proportion of total costs (45%). The total cost burden was approximately 10% higher for men than women, and 63% of overall costs were for persons aged >or=50 years. For diagnosis and management procedures, the estimated average cost per 1000 individuals was Aus$23,560 for men aged >or=50 years from the skin cancer screening trial, compared with Aus$26,967 for BreastScreen Australia and Aus$3042 for the National Cervical Screening Program. CONCLUSIONS: The proportion of costs for benign skin lesions and biopsies arising from the screening programme were no higher than in the two-year period outside the trial. While comparisons are difficult, it appears that diagnostic and management costs for skin cancer as a result of screening may be comparable with those for BreastScreen Australia, if screening is targeted at men aged >or=50 years.

What motivates men age > or =50 years to participate in a screening program for melanoma?

BACKGROUND: The screening behavior and screening outcomes of men age > or =50 years was investigated within a randomized controlled trial of a community-based intervention of screening for melanoma, consisting of a community education program, an education program for medical practitioners, and the provision of dedicated skin-screening clinics. METHODS: Data from cross-sectional telephone surveys before (559 completed interviews), at the end (591 completed interview), and at 2 years after the intervention (445 completed interviews) were analyzed. In addition, the authors analyzed data from skin-screening clinics within the intervention program (3355 men age > or =50 years participated). RESULTS: During the intervention period men age > or =50 years increased both their screening behavior and intention to screen. Those men age > or =50 years who reported a past history of removal of a mole as well as other risk factors for skin cancer and positive attitudes toward screening were more likely to participate in skin screening across time. Men age > or =50 years accounted for 20.5% of all skin-screening clinic attendees, 31.3% of those referred for a suspicious lesion, 48.5% of melanomas, and 45% of all keratinocyte carcinomas diagnosed within the screening program, respectively. CONCLUSIONS: The intervention program successfully motivated men age > or =50 years to attend screening for skin cancer, resulting in the highest yield of skin cancer within this subgroup of the population. Messages addressing skin cancer risk factors and attitudes toward skin cancer and screening could be used to target a screening program for melanoma toward men age > or =50 years.

Who attends skin cancer clinics within a randomized melanoma screening program?

BACKGROUND: Screening may reduce morbidity and mortality associated with melanoma, although in the absence of randomized-controlled trials, this remains unproven. METHODS: As part of a randomized community-based trial of melanoma screening in Queensland, Australia, sociodemographic characteristics, skin cancer risk factors and attitudes towards skin cancer associated with attendance at screening clinics and reasons for attendance or non-attendance were examined. A telephone survey was conducted among 743 attendees and 298 non-attendees. RESULTS: After adjustment, the following factors were associated with clinic attendance: age 40-49 years, having fair skin, a personal history of skin cancer or melanoma or concern about a specific spot or mole, and no recent whole-body skin examination by a doctor. The main reasons for attendance were "to see if I have melanoma", "to have a suspicious mole checked" or "to have a whole-body skin examination". The main reasons for non-attendance were lack of knowledge about the clinics, no time or being away while the clinics were held and having had a skin check in the recent past. Overall, 77% of non-attendees compared to 65% of attendees stated they planned to participate in future screening. CONCLUSIONS: The results suggest that we were able to attract both men and women equally to a skin screening clinic, along with those at all levels of education and indicate the importance of using well-designed promotional materials to attract community members to skin screening clinics. Future work should test strategies to remove barriers to participation in skin screening identified in this study.

Do centralised skin screening clinics increase participation in melanoma screening (Australia)?

OBJECTIVE: To compare during the first 12 months of a 3-year randomised community-based trial of population screening for melanoma three methods of screening delivery: skin screening within day-to-day primary care (Group A); screening in dedicated skin screening clinics either organised privately by local physicians (Group B); or organised centrally with participants referred back to their physicians for definitive diagnosis and management (Group C). METHODS: The trial involved 18 regional communities in Queensland, Australia. Of the nine communities randomised to the intervention group, three communities were allocated to each of the Groups A, B or C. All intervention communities received a community education programme and an education and support programme for primary care physicians. The self-reported prevalence of clinical skin examination was assessed by surveying 3,110 residents (66.9% participation rate) aged > or = 30 years by telephone at baseline, and 14,060 residents (70.9% participation rate) by self-administered mailed questionnaire at 12-month follow-up. RESULTS: At baseline the prevalence of skin screening did not differ between intervention and control communities. At 12-month follow-up, participants within intervention communities reported skin screening significantly more frequently (20.9% versus 10.9%; p < 0.001). Within intervention communities, the prevalence of clinical skin examinations in Group A was similar to that of control communities (12.6% and 10.9%; p = 0.33). Communities in Group B (16.5%; p = 0.001) and Group C (27.1%; p < 0.001) reported significantly higher prevalence of clinical examinations than the control group. CONCLUSIONS: The provision of centrally organised skin screening clinics significantly increases skin screening rates and may have relevance for future melanoma control programmes.

Increase in skin cancer screening during a community-based randomized intervention trial.

Survival from cutaneous melanoma is mainly dependent on the thickness of the lesion at diagnosis. Skin screening may increase detection of thin lesions and hence improve survival. Within a community-based randomized controlled trial of a population screening program for melanoma in Queensland, Australia, 9 communities were randomly assigned to the 3-year intervention and 9 communities to the control group. Skin screening prevalence was monitored by cross-sectional surveys at baseline, 1, 2 and 3 years into the intervention and 2 years later. At baseline, prevalence of whole-body clinical skin examination was similar in intervention and control communities. In intervention communities, the prevalence of whole-body skin examinations increased to 29.2%, an absolute difference of 18% from baseline, with a peak of 34.8% 2 years after baseline, and began to decline again at the end of the intervention period. The largest increases were seen in men and women > or =50 years. Uptake of screening did not differ according to melanoma risk factors; however, the decline in screening was less in participants who reported a number of melanoma risk factors. The prevalence of skin self-examination remained stable during the intervention program. No changes were observed in the control communities. These results indicate that the intervention program significantly increased the prevalence of whole-body clinical skin examinations in intervention communities. Once the intervention program ceased, and particularly after skin clinics ceased, levels of skin screening began to decline. The provision of specialized skin screening clinics may be needed to achieve sufficient screening rates should population based screening for skin cancer be considered.

Clinical outcomes from skin screening clinics within a community-based melanoma screening program.

BACKGROUND: Within a randomized trial of population screening for melanoma, primary care physicians conducted whole-body skin examinations and referred all patients with suspect lesions to their own doctor for further treatment. OBJECTIVE: Our aim was to describe characteristics of skin screening participants, clinical screening diagnoses, management following referral, and specificity and yield of screening examinations. METHODS: Information collected from consent forms, referral forms, and histopathological reports of lesions that had been excised or undergone biopsy was analyzed by means of descriptive statistics. RESULTS: A total of 16,383 whole-body skin examinations resulted in 2302 referrals (14.1% overall; 15.5% men, 18.2% > or = 50 years of age) for 4129 suspect lesions (including 222 suspected melanoma, 1101 suspected basal cell carcinomas [BCCs], 265 suspected squamous cell carcinomas [SCCs]). Histopathologic results were available for 94.8% of 1417 lesions excised and confirmed 33 melanomas (23 in men; 24 in participants > or = 50 years of age), 259 BCCs, and 97 SCCs. The probability of detecting skin cancer of any type within the program was 2.4%. The estimated specificity of whole-body skin examinations for melanoma was 86.1% (95% confidence interval = 85.6-86.6). The positive predictive value (number of confirmed/number of lesions excised or biopsied x 100) for melanoma was 2.5%, 19.3% for BCC, and 7.2% for SCC (overall positive predictive value for skin cancer, 28.9%). LIMITATIONS: Follow-up of participants with a negative screening examination has not been conducted for the present investigation. CONCLUSIONS: The rate of skin cancer detected per 100 patients screened was higher than previously reported and men and attendees older than 50 years more frequently received a referral and diagnosis of melanoma. The specificity for detection of melanoma through whole-body skin examination by a primary care physician was comparable to that of other screening tests, including mammography.

Comparability of skin screening histories obtained by telephone interviews and mailed questionnaires: a randomized crossover study.

The comparability of information collected through telephone interviews and information collected through mailed questionnaires has not been well studied. As part of the first phase of a randomized controlled trial of population screening for melanoma in Queensland, Australia, the authors compared histories of skin examination reported in telephone interviews and self-administered mailed questionnaires. A total of 1,270 subjects each completed a telephone interview and a mailed questionnaire 1 month apart in 1999; 564 subjects received the interview first, and 706 received the mailed questionnaire first. Agreement between the two methods was 91.2% and 88.6% for whole-body skin examination by a physician in the last 12 months and the last 3 years, respectively, and 81.9% for whole-body skin self-examination in the last 12 months. Agreement was lower for "any" skin self-examination. Agreement between the two methods was similar regardless of whether the interview or the questionnaire was administered first. Missing data were less frequent for interviews (0.5%) than for mailed questionnaires (3.8%). Costs were estimated at A$9.55 (US$6.21) per completed interview and A$3.01 (US$1.96) per questionnaire. The similarity of results obtained using telephone interviews and mailed questionnaires, coupled with the substantially higher cost of telephone interviews, suggests that self-administered mailed questionnaires are an appropriate method of assessing this health behavior.

Prevalence of whole-body skin self-examination in a population at high risk for skin cancer (Australia).

OBJECTIVE: Whole-body skin self-examination (SSE) with presentation of suspicious lesions to a physician may improve early detection of melanoma. The aim of this study was to establish the prevalence and determinants of SSE in a high-risk population in preparation for a community-based randomised controlled trial of screening for melanoma. METHODS: A telephone survey reached 3110 residents older than 30 years (overall response rate of 66.9%) randomly selected from 18 regional communities in Queensland, Australia. RESULTS: Overall, 804 (25.9%) participants reported whole-body SSE within the past 12 months and 1055 (33.9%) within the past three years. Whole-body SSE was associated in multivariate logistic regression analysis with younger age (< 50 years); higher education; having received either a whole-body skin examination, recommendation or instruction on SSE by a primary care physicial; giving skin checks a high priority; concern about skin cancer and a personal history of skin cancer. CONCLUSION: Overall, the prevalence of SSE in the present study is among the highest yet observed in Australia, with about one-third of the adult population reporting whole-body SSE in the past three years. People over 50 years, who are at relatively higher risk for skin cancer, currently perform SSE less frequently than younger people.

Attitudes and intentions in relation to skin checks for early signs of skin cancer.

BACKGROUND: Screening for melanoma by whole-body clinical skin examination or skin self-examination may improve early diagnosis of melanoma. As part of the first phase of a community-based randomised controlled trial of screening for melanoma, this study examined the prevalence of skin screening intentions and associated factors in a population at high risk for skin cancer. METHODS: A telephone survey stratified by gender reached 3,110 participants > or = 30 years representative for the population. RESULTS: Overall, 45% intended to have a clinical skin check, and 72% intended to examine their own skin within the next 12 months. In multivariate analysis, a history of a clinical skin examination was most strongly related to intention to screen. Concern about skin cancer or a personal history of skin cancer and high susceptibility towards skin cancer were further important determinants of screening intention. Men were less likely than women to intend participation. CONCLUSIONS: Given that skin screening is not recommended by health authorities in absence of scientific evidence of benefit, the intention to participate in screening for melanoma in this Australian sample was high. Except for the lower intention among men, screening intention appears to be highest in those at highest risk of melanoma.

Prevalence of skin screening by general practitioners in regional Queensland.

OBJECTIVE: To establish the prevalence and predictors of skin screening by general practitioners in regional Queensland. DESIGN: Questionnaire administered to participants by professional interviewers via telephone. PARTICIPANTS AND SETTING: Participants were 3100 adults aged > or = 30 years (66.9% overall response rate), selected from residents of 18 regional Queensland communities with populations of between 2000 and 10 000 (as recorded in the 1996 Australian census). Within the last 10 communities surveyed, an additional telephone survey of 727 participants evaluated mole density. The survey was conducted between January and October 1998. MAIN OUTCOME MEASURE: Prevalence of whole-body skin examinations by GPs. RESULTS: 11% of participants reported a whole-body skin examination by a GP during the previous 12 months, and 20% during the previous 3 years. Men and women reported a similar prevalence of whole-body skin examinations. Factors associated with a significantly increased likelihood of having had a whole-body skin examination within the previous 3 years included a positive attitude towards skin screening, a personal history of non-melanoma skin cancer, a tendency to burn, and having more than four moles on the right upper arm. CONCLUSIONS: A substantial proportion of Queenslanders undergo skin screening. Those at highest risk for skin cancer are more likely to be screened.

Indigenous health: chronically inadequate responses to damning statistics.

In the 10 years 1990-2000, despite improvements in some conditions, there has been little or no overall progress in the health of the Aboriginal and Torres Strait Islander populations of Australia. This is in stark contrast to the gains made in Indigenous health in other countries. The issue is one of lack of commitment to and implementation of already existing policies. We need to (i) fully and adequately fund the Primary Health Care Access Program to provide the out-of-hospital services for prevention and early treatment required to break the cycle of ill-health; (ii) implement a National Training Plan to train the necessary health workforce; and (iii) introduce a National Infrastructure Plan to rectify the continuing deficiencies in water supply, sanitation, education and other basic services.
