Aim: To quantify the proportion of selected notified diseases in NSW attributable to overseas travel and assess the quality of data on travel-associated risk factors, to inform prevention strategies.

Methods: 2010 and 2011 notification data for dengue, hepatitis A, hepatitis E, malaria, paratyphoid fever, shigellosis and typhoid fever were extracted from the NSW Notifiable Conditions Information Management System and analysed for travel-associated risk factors.

Results: Where place of acquisition was known, the proportion of cases for whom the disease was acquired overseas ranged from 48.7% for shigellosis to 100% for hepatitis E, malaria and typhoid. Over half of hepatitis A (53.3%), hepatitis E (74.2%), malaria (54.5%), paratyphoid (53.3%) and typhoid (65.7%) cases were associated with travel to the person's country of birth. Hepatitis A vaccination rates were significantly lower among overseas-acquired than locally-acquired cases (4.8% vs 22.2%, Χ(2)=6.58, p<0.02).

Conclusion: A large proportion of selected enteric and vectorborne disease case notifications were associated with overseas travel. All potential travellers should be made aware of the risks and available preventive measures, such as vaccination against hepatitis A and typhoid fever, taking precautions with food and water and use of malaria chemoprophylaxis, where appropriate. Improvements in data on risk factors, reason for travel and barriers to the use of preventive measures would better inform prevention strategies.

Salmonella Typhimurium is the most common bacterial cause of gastrointestinal disease in NSW. Regular review of surveillance procedures ensures system objectives are met and informs improvements in system utility and efficiency. This paper assesses the timeliness and data completeness of NSW Salmonella Typhimurium surveillance after the routine introduction of multilocus variable repeat analysis (MLVA), a rapid sub-typing technique. MLVA results were available significantly earlier than alternate sub-typing techniques over the 2 years of this review. Accordingly, from a timeliness perspective, MLVA offers a favourable Salmonella Typhimurium sub-typing option in NSW. Further opportunities to improve timeliness and data completeness are identified. This paper was produced as part of a review of Salmonella Typhimurium surveillance in NSW for the period 2008-2009 by members of OzFoodNet based at Hunter New England Population Health. OzFoodNet is a national network established by the then Commonwealth Department of Health and Ageing in 2000 to enhance foodborne disease surveillance in Australia.

Aim: To investigate the distribution of public and private dental practices in NSW in relation to population distribution and socioeconomic status.

Methods: Dental practices (public and private) were mapped and overlayed with Census data on Collection District population and Socio-Economic Indexes for Areas (SEIFA).

Results: Overall, there was an uneven geographic distribution of public and private dental practices across NSW. When the geographic distribution was compared to population socioeconomics it was found that in rural NSW, 12% of the most disadvantaged residents lived further than 50km from a public dental practice, compared to 0% of the least disadvantaged. In Sydney, 9% of the three most disadvantaged groups lived greater than 7.5km from a public dental practice, compared to 21% of the three least disadvantaged groups.

Conclusion: The findings of this study can contribute to informing decisions to determine future areas for focus of dental resource development (infrastructure and workforce) and identifying subgroups in the population (who are geographically isolated from accessing care) where public health initiatives focused on amelioration of disease consequences should be a focus.

Aim: Postpartum haemorrhage rates have been increasing in NSW and internationally, and blood transfusion is required in severe cases. Using routinely collected administrative data provides a convenient method with which to monitor trends in both postpartum haemorrhage and associated transfusion use. In order for this to be feasible however, the reliability of reporting of the conditions needs to be assessed.

Methods: This study used linked data to compare the reporting of postpartum haemorrhage with transfusion as reported in the NSW Admitted Patient Data Collection (hospital data), with the same information obtained from the Perinatal Data Collection (birth data), for births in NSW from 2007 to 2010.

Results: The rate of postpartum haemorrhage requiring blood transfusion was 1.0% based on the hospital data and 1.1% based on the birth data, with a rate of 1.7% if identifying cases from either source. Agreement between the two sources improved from fair to moderate over the time period.

Conclusion: Postpartum haemorrhage requiring transfusion recorded in the birth data shows only moderate agreement with hospital data, so caution is recommended when using this variable for analysis. Linkage of both datasets is recommended to identify birth information from birth data and postpartum haemorrhage with transfusion from hospital data until further validation work has been undertaken.

In western NSW in 2006, a group of Aboriginal Community Controlled Health Organisations identified oral health as a priority need in their regions, considering the lack of regular dental services, poor access to oral health information, and high dental disease rates. A regional oral health promotion program was developed and implemented under the guidance of a regional coordinator who supports local staff in oral health promotion activities such as school-based toothbrushing and the provision of oral health information to targeted groups (e.g. young mothers and carers) and staff of chronic disease programs. The program's strength in its planning and continuity is due to many factors, one of the main being the active involvement of local Aboriginal Community Controlled Health Organisation staff in its genesis, planning and implementation. Combined with strong management support, local partnerships and regional coordination, the program continues to provide collaborative approaches to community-based oral health promotion programs.

The links between tobacco smoking, and periodontal disease and oral cancer make the inclusion of smoking cessation interventions at dental visits an important prevention strategy in oral health services. The 5As (Ask, Advise, Assess, Assist, Arrange), which utilises a stages of change model, is the most commonly recognised framework for the provision of smoking cessation brief interventions and is advocated widely. While the popularity of the 5As continues, increasingly evidence suggests that staged-based interventions in smoking cessation may not be the best approach. Lack of time and expertise are also cited by health professionals as barriers to undertaking brief interventions and thus abbreviated forms of the 5As have been advocated. In 2009, NSW Health introduced a mandatory policy for public dental services in NSW to conduct smoking cessation brief interventions at the chairside based on a three-step approach, which is currently being evaluated. Given the debate and the pending evaluation results, this paper reviews models of smoking cessation brief interventions, to contribute to achieving a best practice model for public oral health in NSW.
