Résumé :

When the Australian Governor General, Sir William Deane, referred in a speech in 1996 to the “appalling problems relating to Aboriginal health” he was not exaggerating. The Australia Bureau of Statistics report on The Health and Welfare of Australia's Aboriginal and Torres Strait Islander Peoples (McLennan & Madden, 1997) outlines the following statistics. The life expectancy for Aboriginal Australians is 15 to 20 years lower than for non-Aboriginal Australians, and is lower than for most countries of the world with the exception of central Africa and India. Aboriginal babies are two to three times more likely to be of lower birth weight and two to four times more likely to die at birth than non-Aboriginal babies. Hospitalisation rates are two to three times higher for Aboriginal than non-Aboriginal Australians. Death rates from infectious diseases are 15 times higher among Aboriginal Australians than non-Aboriginal Australians. Rates for heart disease, diabetes, injury and respiratory diseases are also all higher among Aboriginals – and so the list goes on. It is fair to say that Aboriginal people have higher rates for almost every type of illness for which statistics are currently recorded.

Résumé :

(1) Problem: The increasing incidence and prevalence of infectious diseases in Indigenous Australians (Aboriginal groups and Torres Strait Islanders) are concerning. Indigenous Australians experience the burden of infectious diseases disproportionately when compared to non-Indigenous Australians. (2) Aim: Our report aims to describe how to apply Strengths-Based Nursing (SBN) to ameliorate the impact of the most common infectious diseases in Indigenous Australians. Specifically, we aim to describe how nurses can use SBN to partner with Indigenous Australian communities to remediate, control, and mollify the impact of the most common infectious diseases encountered by them using their limited resources. (3) Methods: Meticulous PubMed, Google Scholar, and web searches were conducted pertaining to Strengths-Based Nursing and common infectious diseases in Indigenous Australians. (4) Findings: The two groups of infectious diseases considered are sexually transmitted infections (STIs) and infectious skin diseases (including parasitic infestations). The prevalence of these infectious diseases in Indigenous Australians is deliberated on, with data when possible, or known trends and impacts. Finally, existing, evidence-based, prudent, and possible SBN approaches are discussed towards tackling these infectious diseases judiciously with available local resources, in conjunction with the support of impacted people, their families, and their communities. (5) Discussion and Conclusion: The SBN approach is a relatively new perspective/approach to clinical and nursing care. In contradistinction to the commonly utilised medical model, SBN pits strengths against deficits, available resources against professional judgment, solutions against unavailable items, and collaborations against hierarchy. In light of the current situation/data, several SBN approaches to combat STIs and skin infections in Indigenous Australians were identified and discussed for the first time in the “Results” section of this paper.

Résumé :

Background Aboriginal and Torres Strait Islanders (Aboriginal) are Australia’s first peoples. Between 2006 and 2015, HIV notifications increased among Aboriginal people; however, among non-Aboriginal people, notifications remained relatively stable. This systematic review and meta-analysis aims to examine the prevalence of HIV among Aboriginal people overall and by subgroups. Methods: In November 2015, a search of PubMed and Web of Science, grey literature and abstracts from conferences was conducted. A study was included if it reported the number of Aboriginal people tested and those who tested positive for HIV. The following variables were extracted: gender; Aboriginal status; population group (men who have sex with men, people who inject drugs, adults, youth in detention and pregnant females) and geographical location. An assessment of between study heterogeneity (I2 test) and within study bias (selection, measurement and sample size) was also conducted. Results: Seven studies were included; all were cross-sectional study designs. The overall sample size was 3772 and the prevalence of HIV was 0.1% (I2 = 38.3%, P = 0.136). Five studies included convenient samples of people attending Australian Needle and Syringe Program Centres, clinics, hospitals and a youth detention centre, increasing the potential of selection bias. Four studies had a sample size, thus decreasing the ability to report pooled estimates. Conclusions: The prevalence of HIV among Aboriginal people in Australia is low. Community-based programs that include both prevention messages for those at risk of infection and culturally appropriate clinical management and support for Aboriginal people living with HIV are needed to prevent HIV increasing among Aboriginal people.

Résumé :

ABSTRACTBackground:A quality dementia-screening tool is required for older remote Aboriginal Australians who have high rates of dementia and limited access to appropriate medical equipment and clinicians. The Kimberley Indigenous Cognitive Assessment (KICA Cog) is a valid cognitive test for dementia in Aboriginal and Torres Strait Islander peoples. The KICA cognitive informant questionnaire (KICA Carer) had yet to be analyzed to determine validity alone or in combination with the KICA Cog.Methods:The KICA Carer was completed by nominated informants of 349 remote-living Aboriginal Australians in the Kimberley region, Western Australia. Validity was assessed by comparing KICA Carer with Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and International Classification of Diseases (ICD-10) consensus diagnoses based on a blinded specialist review. KICA Carer and KICA Cog were then compared to determine joint validity.Results:A KICA Carer score of ≥3/16 gave optimum sensitivity (76.2%) and specificity (81.4%), area under curve (AUC) 0.89 (95% CI = 0.85, 0.94) with positive predictive value (PPV) of 35.8%, and negative predictive value (NPV) of 96.2%. A KICA Cog score of ≤33/39 gave a sensitivity of 92.9% and specificity of 89.9%, AUC 0.96 (95% CI = 0.94, 0.98), with PPV of 55.6% and NPV of 98.9%. Cut-off scores of KICA Cog ≤ 33/39 and KICA Carer ≥ 2/16 in series indicate possible dementia, with sensitivity of 90.5% and specificity of 93.5%. In this setting, PPV was 66.5% and NPV was 98.6%.Conclusions:The KICA Carer is an important tool to accurately screen dementia in remote Aboriginal Australians when the KICA Cog is unable to be used for a patient. It is readily accepted by caregivers.Key points:•For the best practice in the cognitive assessment of an Aboriginal Australian aged over 45 years, KICA Cog should be utilized.•In cases where Aboriginal patients are not assessed directly, KICA Carer should be conducted with an informant. A cut-off score of ≥3/16 should be used (these tools can be downloaded fromwww.wacha.org.au/kica.html).

Résumé :

Tooth decay and gum disease, the main dental diseases affecting Australians, can cause pain and deformity as well as affecting eating and speech. Dental practitioners are efficient and effective in relieving dental pain, and they can effectively restore oral function. There is good evidence that better health care outcomes for Aboriginal and Torres Strait Islander patients are associated with care from Aboriginal and Torres Strait Islander health professionals. Unfortunately, the representation of Aboriginal and Torres Strait Islander people within the dental practitioner workforce is very low. We argue that a strategic approach, along with additional investment, is needed to increase the number of Aboriginal and Torres Strait Islander people qualified as dental practitioners.

Résumé :

Background This paper examines condom use in a sample of Aboriginal young people in New South Wales (NSW) aged 16–30 years. Methods: Cross-sectional data were collected using hand-held computer devices from 293 Aboriginal people attending two Aboriginal events in NSW. Results: Almost two-thirds of respondents reported having had a casual sex partner in the previous 6 months. Of these, 39.2% reported always using a condom with casual partners. Having always used a condom with casual partners varied among respondents, and was more likely among younger respondents (adjusted odds ratio (AOR): 2.7, 95% confidence interval (CI): 1.2–6.1) and less likely among those who used illicit drugs (AOR: 0.2, 95% CI: 0.1–0.7). Conclusions: In comparison to published studies of other Australians, casual sex appears to be more common among this sample of Aboriginal young people; however, the proportion who report having always used condoms with casual partners is very similar. This suggests that although casual sex is more common, Aboriginal young people do not engage in risky behaviour any more often than other young Australians. Further work should be conducted with those who do not always use condoms, such as those who are older and who use illicit drugs, particularly with regards to how abstinence from drug use supports protective behaviours such as condom use among this population of Aboriginal young people.

Texte intégral

Résumé :

Chlamydia are obligate, intracellular, bacterial pathogens that cause three main diseases in humans worldwide: sexually transmitted disease (infertility and pelvic inflammatory disease), trachoma and respiratory infections. Rates of sexually transmitted infections (STIs) due to C. trachomatis are increasing (a 61% increase in notifications in Australia between 2003 and 2007) and the levels in Indigenous Australians continue to be unacceptably high: nearly five times higher than in non-Indigenous people. C. trachomatis also causes the ocular disease trachoma and, unfortunately, this condition continues to be common in Indigenous Australians, a situation that is unacceptable in a developed country. The other chlamydial species that infects humans is C. pneumoniae. While clinically less severe, the Australian Aboriginal population in the Top End have high rates of serologically diagnosed C. pneumoniae infection, which may contribute to the higher rates of respiratory disease observed in this group.

Résumé :

Australia is a unique, geologically ancient island continent. Its flora and fauna are unlike those found anywhere else and the same may be said of its people, politics and health services. The population of 17.3 millions represents a multicultural mix, with an anglo-celtic core conflated by sustained post-war immigration from southern Europe, Turkey, southeast Asia and south America. One in five current Australians was born elsewhere, one in ten comes from a non-English speaking background, and a quarter of those born here have a parent who was born overseas. Aboriginals and Torres Strait Islanders form 1.4% of the total population. They have third world mortality figures but die of first world diseases, their life expectancy being 20 years less than that of other Australians. Two hundred and four years after what they see as the British invasion, their standard of living lags far behind all other socio-cultural groups in the country. Most members of the Aboriginal community do not live long enough to develop Alzheimer's disease, but it and other age-related diseases are emerging as the major determinants of health costs as Australia moves towards the 21st century.

Résumé :

Despite decades of evidence showing that institutional and interpersonal racism serve as significant barriers to accessible healthcare for Aboriginal and Torres Strait Islander Peoples, attempts to address this systemic problem still fall short. The social determinants of health are particularly poignant given the socio-political-economic history of invasion, colonisation, and subsequent entrenchment of racialised practices in the Australian healthcare landscape. Embedded within Euro-centric, bio-medical discourses, Western dominated healthcare processes can erase significant cultural and historical contexts and unwittingly reproduce unsafe practices. Put simply, if Black lives matter in healthcare, why do Aboriginal and Torres Strait Islander Peoples die younger and experience ‘epidemic’ levels of chronic diseases as compared to white Australians? To answer this, we utilise critical race perspectives to theorise this gap and to de-center whiteness as the normalised position of ‘doing’ healthcare. We draw on our diverse knowledges through a decolonised approach to promote a theoretical discussion that we contend can inform alternative ways of knowing, being, and doing in healthcare practice in Australia.

Résumé :

Australian tropical plants have been a rich source of food (bush food) and medicine to the first Australians (Aboriginal people), who are believed to have lived for more than 50,000 years. Plants such as spreading sneezeweed (Centipeda minima), goat’s foot (Ipomoea pes-caprae), and hop bush (Dodonaea viscosa and D. polyandra) are a few popular Aboriginal medicinal plants. Thus far, more than 900 medicinal plants have been recorded in the tropical region alone, and many of them are associated with diverse ethnomedicinal uses that belong to the traditional owners of Aboriginal people. In our effort to find anti-inflammatory lead compounds in collaboration with Aboriginal communities from their medicinal plants, we reviewed 78 medicinal plants used against various inflammation and inflammatory-related conditions by Aboriginal people. Out of those 78 species, we have included only 45 species whose crude extracts or isolated pure compounds showed anti-inflammatory properties. Upon investigating compounds isolated from 40 species (for five species, only crude extracts were studied), 83 compounds were associated with various anti-inflammatory properties. Alphitolic acid, Betulinic acid, Malabaric acid, and Hispidulin reduced proinflammatory cytokines and cyclooxygenase enzymes (COX-1 and 2) with IC50 values ranging from 11.5 to 46.9 uM. Other promising anti-inflammatory compounds are Brevilin A (from Centipeda minima), Eupalestin, and 5′-methoxy nobiletin (from Ageratum conyzoides), Calophyllolide (from Calophyllum inophyllum), and Brusatol (from Brucea javanica). D. polyandra is one example of an Aboriginal medicinal plant from which a novel anti-inflammatory benzoyl ester clerodane diterpenoid compound was obtained (compound name not disclosed), and it is in the development of topical medicines for inflammatory skin diseases. Medicinal plants in the tropics and those associated with indigenous knowledge of Aboriginal people could be a potential alternative source of novel anti-inflammatory therapeutics.

Résumé :

[Truncated abstract] Indigenous Australians suffer cardiovascular disease (CVD) at a rate six times greater than the general population in Australia and while the incidence of CVD has been reduced dramatically amongst the majority of non-indigenous Australians and amongst Indigenous populations in other countries in the last 30 years, there has been little change in the figures for Aboriginal Australians, showing that heart health campaigns have little impact, for this group of people. Aims : The principal aims of this study were firstly, to determine and record the barriers to the development and delivery of CVD prevention programs amongst Indigenous Australians and secondly, to develop an alternative, effective and culturally sensitive method of delivering heart health messages. Methods and results : The study was qualitative research undertaken in three South-West towns of Western Australia where the incidence of CVD was high amongst the Aboriginal community members. The use of semi-formal interviews, informal individual consultation, observation, and focus groups were methods implemented to obtain information. The first phase of the research was to identify the barriers which affected the Aboriginal Health Workers’ ability to deliver specialist educational programs. Questionnaires and interviews with the Aboriginal Health Workers and other health professionals in the towns, and community focus groups were undertaken in this phase of the study. The second phase of the research was aimed at developing an alternative strategy for delivering heart health messages. The focus changed to adopt more traditional ways of passing on information in Indigenous communities. The idea of small gatherings of friends or family with a trusted community member presenting the health message was developed. The third phase of the research was to implement this new approach. Lay educators who had been identified within focus groups and by Aboriginal Health Workers were trained in each of the towns and a protocol involving discussions of health issues, viewing a video on CVD, produced by the National Heart Foundation, sharing in a ‘heart healthy’ lunch and partaking in a ‘heart health’ knowledge game which was developed specifically for the gatherings. Several of these gatherings were held in each of the towns and they became known as ‘HeartAware parties’.

Résumé :

The reading and school performance of Aboriginal and Torres Strait Islander (A & TSI) children has been reported to be poorer than that of the wider community. The known association between reading and vision formed the basis of the principal hypothesis tested in this thesis that the poor reading performance of these children has a visual basis. Two experiments made up the main study which examined the visual characteristics and reading performance of children attending two different urban schools; the Holy Rosary school, which catered for children from many ("mixed") cultural backgrounds and the St Francis school, whose students were predominantly of A & TSI culture. In experiment I, the visual characteristics of 41 A & TSI children (13 from the Holy Rosary school, 28 from the St Francis school), aged between 8 and 11 years were measured. In general, A & TSI children exhibited low hyperopic refractive errors and other optometric findings were similarly within normal limits. Agematched data for 13 A & TSI children from each of the two schools was also compared. Horizontal eye movement ability and reading comprehension skills were significantly poorer in the A & TSI children attending the "mixed" (Holy Rosary) school, while the perceptual skills of the A & TSI students attending the "A & TSI" (St Francis) school were significantly worse. The second experiment investigated the vision and reading performance of A & TSI and non-A & TSI children attending the same school. Age-matched data of 13 A & TSI and 13 non-A & TSI students were analysed. While the visual profiles of the A & TSI and non-A & TSI students were not significantly different, the reading accuracy and comprehension scores were significantly worse in the A & TSI children when compared with the non-A & TSI group. The results from both experiments are consistent with previous reports of poor reading performance in A & TSI children but argue against poor vision being the cause of this reduced reading performance. As an adjunct to this study, the Turtle chart, designed specifically for use with A & TSI children, was evaluated. The vision of 97 students, 60 A & TSI and 37 non-A & TSI students, aged between 6 and 12 years, was measured using both a standard Bailey-Lovie chart and a Turtle chart. The results obtained with the two charts were highly correlated, indicating that the Turtle chart is a culturally appropriate alternative for the measurement of vision in A & TSI children.

Résumé :

Undernutrition in prevalent in Aboriginal communities, in utero, infancy and childhood. It influences childhood morbidity and mortality and growth patterns. Undernutrition and poor socio-economic status also contribute to endemic and epidemic infectious disease, including scabies and streptococcal infection. It has been suggested that early undernutrition, and streptococcal and scabies infection are risk factors for renal disease, which is at epidemic levels and increasing. This thesis examines the prevalence of undernutrition in newborns and infants in an Aboriginal community over time, and its impact on childhood growth and child and adult renal markers. The association between skin lesions, streptococcal serology, post-streptococcal glomerulonephritis (PSGN) and renal markers as evaluated through a community wide screening program in 1992-1995 is also examined. Birthweights have increased since the 1960s, but they are still much lower than the non-Aboriginal values. Weights in infancy have decreased since the 1960s. At screening in childhood stunting was common, reflecting the presence of long-term poor nutrition in infancy. In both adults and children, birth weight and infant weights were negatively associated with albuminuria measured by the albumin to creatine ratio (ACR).

Résumé :

I commenced the Master of Philosophy in Applied Epidemiology (MAE) in February 2015. My field placements were shared between the Communicable Diseases Control Directorate, Public Health Division at the Western Australia Department of Health (CDCD) and the Telethon Kids Institute (TKI), both located in Perth. Two of the three projects that I completed at the CDCD involved a statewide protracted mumps outbreak that went on for the duration of my MAE and reached almost 900 cases. The epidemiology of this outbreak including a discussion about vaccination is presented in Chapter 1. This satisfies the outbreak investigation requirement of the MAE. Chapter 2 comprises a late draft manuscript that explores the vaccine effectiveness (VE) of the measles-mumps-rubella vaccine among paediatric cases during the mumps outbreak. I designed and carried out a matched case-control study using paediatric outbreak cases and controls from a population database. I measured VE using a conditional logistic regression model and compared it with the screening method. Both methods yielded a very low VE this population. This is likely due to a multitude of factors that are discussed in the chapter. My work at TKI involved a data analysis using linked-administrative data on a total population birth cohort involving all children born in Western Australia between 1996-2012. I explored the burden of hospital separations that resulted from otitis media (OM), the most common infectious disease in children, and a common related procedure, myringotomy with ventilation tube insertion (MVTI). I calculated the age-specific hospitalisation rates for OM and MVTI over the study years. The second part of this analysis involved investigating the maternal and infant risk factors and population attributable fractions for OM-related hospitalisation in early life. This work was important because of its implications for practice. All of this is presented in Chapter 3. Chapter 4 is an evaluation of SmartVax, a novel, real-time Adverse Events Following Immunisation (AEFI) surveillance system using SMS text messages to communicate directly with vaccinees after their vaccination. This was the third project that I completed at the CDCD. The chapter begins with a peer-reviewed publication, Continuous active surveillance of adverse events following immunisation using SMS technology, that describes the system and analyses data outputs for children <5 years from 2011-2015. I have included the publication first to provide a brief system overview including summarised surveillance data, to give context to the evaluation since SmartVax is a relatively new and developing system. The publication is followed by the formal evaluation. Finally, I include a summary of the teaching exercises that I was involved in during my MAE. The first was a “lesson from the field” where I prepared an exercise for my fellow scholars. The exercise was useful for me and the feedback from my colleagues was positive. The second was a collaborative teaching exercise about confounding that we taught to the first year MAE scholars on their last day of courseblock. These combined activities at both placements have enriched my understanding of epidemiology while working in health and research environments.

Résumé :

Until recently, there was no dementia screening tool for Indigenous Australians and a paucity of information on the extent of dementia in Indigenous Australians. This thesis describes the development and validation of a tool to assess cognitive impairment in remote Indigenous Australians with the primary purpose of determining the prevalence of dementia and other associated conditions in this population. The tool was reevaluated with the larger prevalence sample and a short version of the tool was developed and evaluated. The Kimberley Indigenous Cognitive Assessment (KICA) tool was validated with Indigenous Australians aged over 45 years from the Kimberley region of Western Australia (n=70). The results were later confirmed in a larger sample from the remote Kimberley (n=363), and an additional sample in rural and remote areas of the Northern Territory (n=47). The KICA results were compared to independent consensus diagnoses using DSM-IV and ICD-10. Interpreters were used whenever participants were not proficient in English. These data led to the determination of a cut-off score of 33/34 out of a possible total score of 39 for the cognitive component of the KICA (KICA-Cog), with a sensitivity of 0.93 and specificity of 0.95 and AUC of 0.98. The tool is now widely used within remote areas of Australia. A short version of the KICACog (sKICA-Cog) was developed and found to be a valid brief screening tool for dementia in the Kimberley population, and had a cut-off score of 20/21 out of a possible 25, with a sensitivity of 0.89, specificity of 0.95 and AUC of 0.98. The sKICA-Cog should be used in combination with the KICA cognitive informant questionnaire (KICA-IQ). The KICA-IQ cut-off score of 2/3 out of a possible 16 was determined, with a sensitivity of 0.76 and specificity of 0.84 and AUC of 0.91. Using the validated KICA, the prevalence of dementia and cognitive impairment not dementia (CIND) was determined in a semi-purposive sample consisting of 363 Indigenous Australians aged over 45 years from 6 Aboriginal communities and one town in the Kimberley region. Participants were screened with the full KICA and 165 participants had an independent specialist review with consensus diagnoses. The prevalence of dementia was 12.4%, 5.2 times greater than the Australian prevalence of 2.4%, after age adjustment. The prevalence of CIND was 8.0%. Characteristics associated with dementia included older age, male gender (OR 3.1, 95% CI 1.4, 6.8), no formal education (OR 2.7, 95% CI 1.1, 6.7), smoking (OR 4.5, 95% CI 1.1, 18.6), previous stroke (OR 17.9, 95% CI 5.9, 49.7), epilepsy (OR 33.5, 95% CI 4.8, 232.3) and head injury (OR 4.0, 95% CI 1.7, 9.4). Other factors associated with dementia included incontinence, falls and poor mobility. The KICA is a valid assessment tool for rural and remote Indigenous Australians. The prevalence of dementia amongst Indigenous Australians is substantially higher than generally found in non - Indigenous Australians and other populations in the developed and developing world.

Résumé :

Succeeding phases of British economic growth prompted strikingly different imperatives for expansion, for natural resource exploitation, and for the social organization of extra-European production. In the eighteenth century, sugar, African slaves, and shipping in the Atlantic world provided one major dynamic of empire. But in the nineteenth century, antipodean settlement and trade, especially that resulting from expanding settler pastoral frontiers, was responsible for some of the most dramatic social and environmental transformations. Plantations occupied relatively little space in the new social geography of world production. By contrast, commercial pastoralism, which took root most energetically in the temperate and semi-arid regions of the newly conquered world, was land-hungry but relatively light in its demands for labour. The Spanish Empire based in Mexico can be considered a forerunner. By the 1580s, within fifty years of their introduction, there were an estimated 4.5 million merino sheep in the Mexican highlands. The livestock economy, incorporating cattle as well as sheep, spread northwards through Mexico to what became California by the eighteenth century. Settler intrusions followed in the vast landmasses of southern Latin America, southern Africa, Australia, and New Zealand. Australia was one of the last-invaded of these territories, and, in respect of the issues that we are exploring, was in some senses distinctive. Unlike Canada and South Africa, there was no long, slow period of trade and interaction with the indigenous population; like the Caribbean, the Aboriginal people were quickly displaced by disease and conquest. The relative scale of the pastoral economy was greater than in any other British colony. Supply of meat and dairy products to rapidly growing ports and urban centres was one priority for livestock farmers. Cattle ranching remained a major feature of livestock production in Australia. Bullock-carts, not dissimilar to South African ox-wagons, were essential for Australian transport up to the 1870s. But for well over a century, from the 1820s to the 1950s and beyond, sheep flooded the southern lands. Although mutton became a significant export from New Zealand and South America, wool was probably the major product of these pastoral hinterlands—and a key focus of production in Australia and South Africa. The growth in antipodean sheep numbers was staggering.

« cases, have been from Western Australia, with a further thirteen cases from the Northern Territory. It is also interesting to note that the first confirmed case of encephalitis due to Kunjin virus occurred in Western Australia in 1978, and three additional cases have been diagnosed since, two from Western Australia in 1991 and 1995, and one in Victoria in 1984 (Table 8.1). Most of the cases of Australian encephalitis in Western Australia have occurred in areas distant from the Ord River irrigation area. Of particular significance was the spread of MVE virus from the Kimberley area south to the Pilbara and Gascoyne regions causing one case of encephalitis in 1978 and three cases in 1981. It is hypothesized that movement of virus to the Pilbara region in 1978 was due to an increase in viral activity in the West Kimberley area following heavy rainfall and flooding, and that with subsequent extensive cyclonic rainfall in the Pilbara region, viraemic waterbirds moved south down the narrow coastal strip, introducing the virus into Pilbara (Stanley 1979). It is probable that a similar mechanism may have occurred in 1981. Although there has been evidence (see next section), of MVE virus activity in the Pilbara region in recent years, there have been no further cases. Analysis of the cases of Australian encephalitis has indicated that Aboriginal infants, particularly male infants, are most at risk of fatal or severe disease (Mackenzie et al. 1993a). However, tourists and visitors to the Kimberley region (and Northern Territory) have also been shown to have an increased risk of disease. Sentinel chicken surveillance Following the 1978 outbreak of Australian encephalitis, a number of sentinel chicken flocks were established in the Kimberley area. Six flocks had been established by 1981 and the number rose to twenty-four flocks in twenty-two regional centres in the Kimberley, Pilbara and Gascoyne regions by 1989 (Broom et al. 1989 ; Mackenzie et al. 1992 ; 1994c). Each flock contains twelve chickens which are bled at two weekly intervals between November and June, the period of increased risk of virus transmission, and monthly at other times. The sera are then assayed for antibody to MVE and Kunjin viruses in our laboratory in Perth to provide an early warning system of increased virus activity. Initially sera were tested by HI for the presence of antibody, and positive sera were then subjected to neutralization assay to determine the identity of the infecting virus. A more rapid enzyme-linked immunosorbent assay (ELISA) was introduced in 1986 (Broom et al. 1987), and more recently a competitive ELISA using specific monoclonal antibodies to identify the virus is being used (Hall et al. 1992 ; 1995). Sentinel chicken flocks were also established in 1992 in the Northern Territory to monitor MVE activity (Aldred et al. 1992). The sentinel chicken programme has clearly shown that MVE virus is enzootic in several areas of the Kimberley region, particularly in the Ord River area at Kununurra. Seroconversions in sentinel chickens occur every year during the latter half of the wet season ». Dans Water Resources, 131. CRC Press, 1998. http://dx.doi.org/10.4324/9780203027851-24.

Résumé :

Background Lung cancer is the number one cause of cancer death worldwide.(1) It is the fifth most commonly diagnosed cancer in Australia (12,741 cases diagnosed in 2018) and the leading cause of cancer death.(2) The number of years of potential life lost to lung cancer in Australia is estimated to be 58,450, similar to that of colorectal and breast cancer combined.(3) While tobacco control strategies are most effective for disease prevention in the general population, early detection via low dose computed tomography (LDCT) screening in high-risk populations is a viable option for detecting asymptomatic disease in current (13%) and former (24%) Australian smokers.(4) The purpose of this Evidence Check review is to identify and analyse existing and emerging evidence for LDCT lung cancer screening in high-risk individuals to guide future program and policy planning. Evidence Check questions This review aimed to address the following questions: 1. What is the evidence for the effectiveness of lung cancer screening for higher-risk individuals? 2. What is the evidence of potential harms from lung cancer screening for higher-risk individuals? 3. What are the main components of recent major lung cancer screening programs or trials? 4. What is the cost-effectiveness of lung cancer screening programs (include studies of cost–utility)? Summary of methods The authors searched the peer-reviewed literature across three databases (MEDLINE, PsycINFO and Embase) for existing systematic reviews and original studies published between 1 January 2009 and 8 August 2019. Fifteen systematic reviews (of which 8 were contemporary) and 64 original publications met the inclusion criteria set across the four questions. Key findings Question 1: What is the evidence for the effectiveness of lung cancer screening for higher-risk individuals? There is sufficient evidence from systematic reviews and meta-analyses of combined (pooled) data from screening trials (of high-risk individuals) to indicate that LDCT examination is clinically effective in reducing lung cancer mortality. In 2011, the landmark National Lung Cancer Screening Trial (NLST, a large-scale randomised controlled trial [RCT] conducted in the US) reported a 20% (95% CI 6.8% – 26.7%; P=0.004) relative reduction in mortality among long-term heavy smokers over three rounds of annual screening. High-risk eligibility criteria was defined as people aged 55–74 years with a smoking history of ≥30 pack-years (years in which a smoker has consumed 20-plus cigarettes each day) and, for former smokers, ≥30 pack-years and have quit within the past 15 years.(5) All-cause mortality was reduced by 6.7% (95% CI, 1.2% – 13.6%; P=0.02). Initial data from the second landmark RCT, the NEderlands-Leuvens Longkanker Screenings ONderzoek (known as the NELSON trial), have found an even greater reduction of 26% (95% CI, 9% – 41%) in lung cancer mortality, with full trial results yet to be published.(6, 7) Pooled analyses, including several smaller-scale European LDCT screening trials insufficiently powered in their own right, collectively demonstrate a statistically significant reduction in lung cancer mortality (RR 0.82, 95% CI 0.73–0.91).(8) Despite the reduction in all-cause mortality found in the NLST, pooled analyses of seven trials found no statistically significant difference in all-cause mortality (RR 0.95, 95% CI 0.90–1.00).(8) However, cancer-specific mortality is currently the most relevant outcome in cancer screening trials. These seven trials demonstrated a significantly greater proportion of early stage cancers in LDCT groups compared with controls (RR 2.08, 95% CI 1.43–3.03). Thus, when considering results across mortality outcomes and early stage cancers diagnosed, LDCT screening is considered to be clinically effective. Question 2: What is the evidence of potential harms from lung cancer screening for higher-risk individuals? The harms of LDCT lung cancer screening include false positive tests and the consequences of unnecessary invasive follow-up procedures for conditions that are eventually diagnosed as benign. While LDCT screening leads to an increased frequency of invasive procedures, it does not result in greater mortality soon after an invasive procedure (in trial settings when compared with the control arm).(8) Overdiagnosis, exposure to radiation, psychological distress and an impact on quality of life are other known harms. Systematic review evidence indicates the benefits of LDCT screening are likely to outweigh the harms. The potential harms are likely to be reduced as refinements are made to LDCT screening protocols through: i) the application of risk predication models (e.g. the PLCOm2012), which enable a more accurate selection of the high-risk population through the use of specific criteria (beyond age and smoking history); ii) the use of nodule management algorithms (e.g. Lung-RADS, PanCan), which assist in the diagnostic evaluation of screen-detected nodules and cancers (e.g. more precise volumetric assessment of nodules); and, iii) more judicious selection of patients for invasive procedures. Recent evidence suggests a positive LDCT result may transiently increase psychological distress but does not have long-term adverse effects on psychological distress or health-related quality of life (HRQoL). With regards to smoking cessation, there is no evidence to suggest screening participation invokes a false sense of assurance in smokers, nor a reduction in motivation to quit. The NELSON and Danish trials found no difference in smoking cessation rates between LDCT screening and control groups. Higher net cessation rates, compared with general population, suggest those who participate in screening trials may already be motivated to quit. Question 3: What are the main components of recent major lung cancer screening programs or trials? There are no systematic reviews that capture the main components of recent major lung cancer screening trials and programs. We extracted evidence from original studies and clinical guidance documents and organised this into key groups to form a concise set of components for potential implementation of a national lung cancer screening program in Australia: 1. Identifying the high-risk population: recruitment, eligibility, selection and referral 2. Educating the public, people at high risk and healthcare providers; this includes creating awareness of lung cancer, the benefits and harms of LDCT screening, and shared decision-making 3. Components necessary for health services to deliver a screening program: a. Planning phase: e.g. human resources to coordinate the program, electronic data systems that integrate medical records information and link to an established national registry b. Implementation phase: e.g. human and technological resources required to conduct LDCT examinations, interpretation of reports and communication of results to participants c. Monitoring and evaluation phase: e.g. monitoring outcomes across patients, radiological reporting, compliance with established standards and a quality assurance program 4. Data reporting and research, e.g. audit and feedback to multidisciplinary teams, reporting outcomes to enhance international research into LDCT screening 5. Incorporation of smoking cessation interventions, e.g. specific programs designed for LDCT screening or referral to existing community or hospital-based services that deliver cessation interventions. Most original studies are single-institution evaluations that contain descriptive data about the processes required to establish and implement a high-risk population-based screening program. Across all studies there is a consistent message as to the challenges and complexities of establishing LDCT screening programs to attract people at high risk who will receive the greatest benefits from participation. With regards to smoking cessation, evidence from one systematic review indicates the optimal strategy for incorporating smoking cessation interventions into a LDCT screening program is unclear. There is widespread agreement that LDCT screening attendance presents a ‘teachable moment’ for cessation advice, especially among those people who receive a positive scan result. Smoking cessation is an area of significant research investment; for instance, eight US-based clinical trials are now underway that aim to address how best to design and deliver cessation programs within large-scale LDCT screening programs.(9) Question 4: What is the cost-effectiveness of lung cancer screening programs (include studies of cost–utility)? Assessing the value or cost-effectiveness of LDCT screening involves a complex interplay of factors including data on effectiveness and costs, and institutional context. A key input is data about the effectiveness of potential and current screening programs with respect to case detection, and the likely outcomes of treating those cases sooner (in the presence of LDCT screening) as opposed to later (in the absence of LDCT screening). Evidence about the cost-effectiveness of LDCT screening programs has been summarised in two systematic reviews. We identified a further 13 studies—five modelling studies, one discrete choice experiment and seven articles—that used a variety of methods to assess cost-effectiveness. Three modelling studies indicated LDCT screening was cost-effective in the settings of the US and Europe. Two studies—one from Australia and one from New Zealand—reported LDCT screening would not be cost-effective using NLST-like protocols. We anticipate that, following the full publication of the NELSON trial, cost-effectiveness studies will likely be updated with new data that reduce uncertainty about factors that influence modelling outcomes, including the findings of indeterminate nodules. Gaps in the evidence There is a large and accessible body of evidence as to the effectiveness (Q1) and harms (Q2) of LDCT screening for lung cancer. Nevertheless, there are significant gaps in the evidence about the program components that are required to implement an effective LDCT screening program (Q3). Questions about LDCT screening acceptability and feasibility were not explicitly included in the scope. However, as the evidence is based primarily on US programs and UK pilot studies, the relevance to the local setting requires careful consideration. The Queensland Lung Cancer Screening Study provides feasibility data about clinical aspects of LDCT screening but little about program design. The International Lung Screening Trial is still in the recruitment phase and findings are not yet available for inclusion in this Evidence Check. The Australian Population Based Screening Framework was developed to “inform decision-makers on the key issues to be considered when assessing potential screening programs in Australia”.(10) As the Framework is specific to population-based, rather than high-risk, screening programs, there is a lack of clarity about transferability of criteria. However, the Framework criteria do stipulate that a screening program must be acceptable to “important subgroups such as target participants who are from culturally and linguistically diverse backgrounds, Aboriginal and Torres Strait Islander people, people from disadvantaged groups and people with a disability”.(10) An extensive search of the literature highlighted that there is very little information about the acceptability of LDCT screening to these population groups in Australia. Yet they are part of the high-risk population.(10) There are also considerable gaps in the evidence about the cost-effectiveness of LDCT screening in different settings, including Australia. The evidence base in this area is rapidly evolving and is likely to include new data from the NELSON trial and incorporate data about the costs of targeted- and immuno-therapies as these treatments become more widely available in Australia.
