Background: The analysis aimed to assess the Indigenous status of an increasing number of deaths not coded with a useable Indigenous status from 1997 to 2002 and its impact on reported recent gains in Indigenous mortality. Methods: The Indigenous status of WA death records with a missing Indigenous status was determined based upon data linkage to three other data sources (Hospital Morbidity Database System, Mental Health Information System and Midwives Notification System). Results: Overall, the majority of un-coded cases were assigned an Indigenous status, with 5.9% identified as Indigenous from the M1 series and 7.5% from the M2 series. The significant increase in Indigenous male LE of 5.4 years from 1997 to 2002 decreased to 4.0 and 3.6 years using the M1 and M2 series, respectively, but remained significant. For Indigenous females, the non-significant increase in LE of 1.8 years from 1997 to 2002 decreased to 1.0 and 0.6 years. Furthermore, annual all-cause mortality rates were higher than in the original data for both genders, but the significant decline for males remained. Conclusion: Through data linkage, the increasing proportion of deaths not coded with a useable Indigenous status was shown to impact on Indigenous mortality statistics in Western Australia leading to an overestimate of improvements in life expectancy. Greater attention needs to be given to better identification and recording of Indigenous identifiers if real improvements in health status are to be demonstrated. A system that captures an individual's Indigenous status once and is reflected in all health and administrative data systems needs consideration within Australia.

Objective: Cancer among Indigenous populations in the developed world appears to have increased over past few decades. This article explores issues related to cancer among the Indigenous populations of Australia, Canada, New Zealand and the US and examines variations in the epidemiology, Indigenous peoples' perceptions about cancer and potential effects on care-seeking behaviour. Methods: A search of peer-reviewed journal articles, government reports, published and unpublished theses and other grey literature was undertaken using electronic databases and citation snowballing. Both epidemiological and qualitative studies were included. Results: Cancer in Indigenous populations in these four countries is characterised by high incidence and mortality rates for specific cancers and lower survival rates as a result of late diagnosis, lower participation and poorer compliance with treatment. A higher prevalence of many cancer risk factors occurs across these populations. Fear of death, fatalism, payback, shame and other spiritual and cultural issues are reported in the few qualitative studies examining Indigenous beliefs and understanding of cancer which undoubtedly influences participation in cancer screening and treatment. Conclusions and implications: The holistic approach (physical, mental, emotional and spiritual) to healing and well-being, and the concept that individual, family and community are inseparable underpin Indigenous care-seeking behaviour. Further community-based research is needed to increase understanding of the needs of Indigenous people with cancer, and to guide policy and practice towards more supportive and effective care. Key words: Health services, Indigenous, Neoplasms, culture, holistic health.

Objective: To provide practical advice to health care providers and public health practitioners regarding screening and management of sexually transmitted infections (STIs) in sex workers, and to examine the effectiveness of condoms in reducing transmission of STIs. Methods: Medline search using the key words sex workers, prostitutes, condoms and these terms in conjunction with pregnancy, sexually transmitted infections (including the names of individual STIs), infectivity, exclusion periods. Additional articles were identified from cited references. Articles were selected on the basis of information provided on efficacy of condoms in ST1 prevention, prevalence of STIs in sex workers and changes following condom promotion, and advice about management of STIs in infected workers. Results: Condoms offer some protection (30-90%) against STIs passed in semen, urethral, vaginal or cervical secretions (such as HIV, gonorrhoea, chlamydia). They give little to no protection (0-30%) against diseases due to skin-to-skin contact such as genital herpes and genital warts. Transmissibility of STIs varies according to the sex of the exposed person and the sexual practice. Condom effectiveness against STIs also varies with gender, and experience and consistency of condom use. Conclusions: Sex workers require regular screening for STIs as condom use is not fully protective. Management of sex workers identified with infection requires understanding of the issues faced by sex workers, biological characteristics of the infective organism, treatment efficacy, and test sensitivity and specificity. Advice on frequency of STI testing, supply of medical certificates, management of condom breakage, and management of infected sex workers is proposed.

Background: More than 30 million needle syringes are distributed per year in Australia as a component of harm-reduction strategies for injecting drug users (IDU). Discarded needle syringes create considerable anxiety within the community, but the extent of needlestick injuries and level of blood-borne virus transmission risk is unclear. We have undertaken a review of studies of blood-borne virus survival as the basis for advice and management of community needlestick injuries. Methods: A Medline review of published articles on blood-borne virus survival and outcome from community injuries. Results: Hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) can all survive outside the human body for several weeks, with virus survival influenced by virus titer, volume of blood, ambient temperature, exposure to sunlight and humidity. HBV has the highest virus titers in untreated individuals and is viable for the most prolonged periods in needle syringes stored at room temperature. However, prevalence of HBV and HIV are only 1-2% within the Australian IDU population. In contrast, prevalence of HCV is 50-60% among Australian IDUs and virus survival in needle syringes has been documented for prolonged periods. There have been no published cases of blood-borne virus transmission following community needlestick injury in Australia. Conclusion: The risk of blood-borne virus transmission from syringes discarded in community settings appears to be very low. Despite this, procedures to systematically follow up individuals following significant needlestick exposures sustained in the community setting should be developed.
