Accuracy of national mortality codes in identifying adjudicated cardiovascular deaths

Objective: This study investigated the sensitivity and specificity of the national mortality codes in identifying cardiovascular disease (CVD) deaths and documents methods of verification.

Methods: A 12-year retrospective case ascertainment of all ICD-coded CVD deaths was performed for deaths between 1990 and 2002 in the Melbourne Collaborative Cohort Study, comprising 41,528 subjects. Categories of non-CVD codes were also examined. Stratified samples of 750 deaths were adjudicated from a total of 2,230 deaths. Expert panels of cardiologists and neurologists adjudicated deaths.

Results: Of the 750 deaths adjudicated, 582 were verified as CVD [392 coronary heart disease (CHD) and 92 stroke] and 168 non-CVD. Estimated sensitivity and specificity of national mortality codes for identifying specific causes of death were: CHD 74.2% (95% CI: 69.8–78.5%) and 97.6% (96.0–99.2%), respectively; myocardial infarction 59.9% (50.9–69.0%) and 94.2% (92.4–96.0%), respectively; haemorrhagic stroke 58.9% (46.0–71.7%) and 99.8% (99.4–100.0%), respectively and; ischaemic stroke 38.7% (20.5–56.9%) and 99.9% (99.6–100.0%), respectively. Misclassification was most common for deaths with primary ICD codes for endocrine-metabolic and genito-urinary diseases.

Conclusions: National mortality coding under-estimated the true proportion of CHD and stroke deaths in the cohort by 13.6% and 50.8%, respectively.

Australia's health 2002 : the eighth biennial report of the Australian Institute of Health and Welfare

Australia's Health 2002 is the eighth biennial health report of the Australian Institute of Health and Welfare. It is the nation's authoritative source of information on patterns of health and illness, determinants of health, the supply and use of health services, and health service costs and performance. Australia's Health 2002 is an essential reference and information resource for all Australians with an interest in health.

Spirit-music unbound: Romanticism and print politics in Australian women's poetry 1830-1905

This thesis presents a re-mapping of Australian poetic tradition to reflect the presence of colonial women poets. The research recovers a wide range of neglected poetry, offering a new way of reading these important poets as politic and transnational, particularly through the significance of newspaper authorship and international women’s poetry.

Unthinkable

'Unthinkable' was an installation comprising drawings and fabric works placed onto a wall painting. This work engages with the gender politics of art criticism through strategies of redrawing and (re)performance, in particular the commentary that Helen Frankenthaler's painting practice was 'unthinkable' without Jackson Pollock.

A randomized controlled trial of vocational intervention for young people with first-episode psychosis : method

Young people who are experiencing first-episode psychosis (FEP) are at increased risk of being unemployed compared to either their same age peers in the general population, or those with other mental illnesses. Significant research has been conducted examining employment interventions for those with chronic psychotic illness. This has yielded strong results in favour of an intervention called individual placement and support (IPS). However, significantly less work has examined the benefit of this approach to those in FEP when the potential for vocational rehabilitation is perhaps greater. This study adds to the knowledge of vocational intervention in first-episode psychotic illness. Additionally, it expands this work into the areas of cognition, social cognition, social inclusion and economics.

Norms and their relationship to behavior in worksite settings : an application of the Jackson Return Potential Model

To measure health norms and assess their influence on behavior among 2541 employees in 16 manufacturing worksites using an adapted Jackson's Return Potential Model (RPM). METHODS: Worksite-level norm intensity, crystallization, and normative power were calculated for several behaviors; linear regression analyses tested whether normative power was related to each health behavior. RESULTS: Norms about safe work practices and smoking were most intense; norms about safe work practices were most crystallized. Safe work practices and smoking held the highest normative power; healthy eating held the least normative power. Comparing norm characteristics across health behaviors leads to important leverage points for intervening to influence norms and improve worker health.

Marketing ethics in context: the promotion of unhealthy foods and beverages to children

Marketing ethics has been described as an inherently relative conceptwhereby ethical problems and consequences result from interactionsbetween individuals, but are also shaped by the context in which theyoccur (Chonko and Hunt 1985; Singhapakdi et al. 1996). In makingethical decisions, marketers are influenced by a complex interplay offactors in the broader cultural, economic and organizational environments(Singhapakdi et al. 1996). Within this field, issues arise from organizations’ marketing activities and their consequences (Chonko and Hunt 1985), and the way marketing decisions are shaped by moral standards (Murphy et al. 2005).
