Epidemiology of syphilis in the Nepean and Blue Mountains Local Health District between 1 October 2009 and 30 September 2019.

Background: Syphilis is a nationally notifiable sexually transmitted infection (STI). Rates of syphilis notifications have been on the increase in Australia. Given these increases, we wanted to study the epidemiological trends of syphilis notifications in the Nepean Blue Mountain Local Health District (NBMLHD) over a ten-year period across different healthcare settings. Methods: All syphilis notifications in residents in the NBMLHD in the ten-year period between 1 October 2009 and 30 September 2019 were included in the study. Separate analyses were performed for all syphilis notifications, as well as for infectious syphilis and for syphilis acquired > 2 years ago or of unknown duration. We described age distribution and demographic profile and risk factors of all syphilis notifications. Notification trends were studied and crude incidence rates were calculated. Notifications were stratified by stage of syphilis, sex, and geographical location. Results: In the study duration, a total of 342 notifications of syphilis were received. Of these, 187 were infectious syphilis and 155 were related to infections acquired > 2 years ago and/or of unknown duration. The majority of notifications were in men: 281 (82%). Overall, syphilis notifications increased over the ten-year study period. The crude incidence rates for infectious syphilis were significantly higher in the second five-year period overall (7.78/100,000 population per year compared to 5.28/100,000 population per year; incidence rate ratio (IRR): 1.47; 95% confidence interval (95% CI): 1.10-1.97; p < 0.01), as well as for males (14.44/100,000 population per year compared to 9.7/100,000 population per year; IRR: 1.49; 95% CI: 1.09-2.03; p < 0.01). There were significant increases in syphilis notifications in males < 35 years of age, from 39 such notifications in the first five-year period (27.5% of all syphilis notifications in this period) to 83 notifications in the second five-year period (42.1% of all notifications in this period), p < 0.05. Conclusion: In keeping with national trends, notifications in our study increased. Significant increases were noted in notifications among males under 35 years of age. This supports the continued investment in sexual health promotion activities aimed at young sexually active men. Expansion of screening activities to include women and older people would help detect any increase in cases in these groups. Increase in engagement with general practitioners will support them to provide opportunistic STI screens to sexually-active attendees. National screening recommendations remain applicable to this population.

Exploring complementary medicine practitioners' attitudes towards the use of an immunization decision aid, and its potential acceptability for use with clients to reduce vaccine related decisional conflict.

While Australia boasts a high immunization rate, geographical pockets of low uptake still challenge herd immunity on a community level. For some parents, concerns about immunization lead to distrust of conventional sources of vaccine information and complementary medicine (CM) practitioners may be more readily trusted as a source of information about vaccines. Decision aids are common educational resources that are developed to support informed decision making. We interviewed CM practitioners to explore their attitudes to immunization decision aids in general and the acceptability of recommending this resource to parents with concerns or questions about immunization. While some practitioners felt that it might be biased towards immunizations, all said that they would recommend the resource to parents. CM practitioners are a trusted source of information, including immunization advice for some parents. CM practitioners were generally supportive of decision aids as a tool they could use in their practice to help parents with immunization questions, where a premium is often placed on patient choice.

Demographic and geographical risk factors for gonorrhoea and chlamydia in greater Western Sydney, 2003-2013.

INTRODUCTION: Notification rates of sexually transmitted infections (STIs) have increased in New South Wales as elsewhere in Australia. Understanding trends in chlamydia and gonorrhoea notifications at smaller geographical areas may assist public health efforts to deliver targeted STI interventions. METHODS: Routinely collected disease notification data from 2 local health districts within the greater Western Sydney area were analysed. De-identified notifications of gonorrhoea and chlamydia were extracted for people aged over 15 years during the period 1 January 2003 to 31 December 2013. Sex-specific and age-specific population notification rates for each infection were calculated. Incidence rate ratios were also calculated with age group, sex, year and local government area (LGA) of residence as explanatory variables. RESULTS: Rates of gonorrhoea and chlamydia increased among males and females over the period. Males had a 4-fold increased risk of gonorrhoea (P<0.0001). Compared with the 30-44 years age group, young people aged 15-29 years had a 70% increased risk of gonorrhoea and a 4-fold increased risk of chlamydia (P values < 0.0001). Chlamydia notifications demonstrated smaller and more uniform annual increases across LGAs compared with gonorrhoea notifications, which appeared more highly clustered. CONCLUSION: Analysis of notification rates of chlamydia and gonorrhoea in the greater Western Sydney area suggest that young people aged 15-29 years and residents of particular LGAs are at greater risk of infection. A limitation was the unknown effect of patterns of testing. Nevertheless, these results can support the planning of local sexual health clinical services as well as the design of targeted health promotion interventions.

General Practitioners' Perception of Risk for Travelers Visiting Friends and Relatives.

BACKGROUND: General practitioners (GPs) are an important source of pre-travel health advice for travelers; however, only a few studies have investigated primary healthcare provider-related barriers to the provision of pre-travel health advice, particularly to travelers visiting friends and relatives (VFR). We aimed to investigate Australian GPs' knowledge, attitudes, and practices with regard to VFR travelers. METHODS: A postal survey was sent to randomly sampled GPs in Sydney, Australia, in 2012. The questionnaire investigated GPs' perception of risk and barriers to the provision of advice to VFR travelers. RESULTS: Of 563 GPs, 431 (76.6%) spoke a language other than English (LOTE) with 361 (64.1%) consulting in a LOTE. Overall, 222 (39.4%) GPs considered VFR travelers to be at higher risk than holiday travelers, with GPs consulting in English only [adjusted odds ratio (aOR) 1.65, 95% confidence interval (CI) 1.11-2.44, p = 0.01] and GPs considering long-term migrants as VFR travelers (aOR 1.86 95% CI 1.07-3.23, p = 0.03) remaining significant on multivariate analysis. CONCLUSIONS: Multilingual GPs are a valuable resource to reducing language and cultural barriers to healthcare. Targeted education of this subgroup of GPs may assist in promoting pre-travel health assessments for VFR travelers. Awareness of the need for opportunistic targeting of migrants for pre-travel consultation through routine identification of future travel is needed.

Enhanced surveillance of hepatitis B infection in inner-western Sydney.

OBJECTIVES: We developed an enhanced surveillance system for hepatitis B to improve the detection of newly acquired cases and to collect epidemiological data. METHODS: The study was undertaken from February to June (inclusive) 2005 at the Sydney South West Area Health Service Eastern Zone Public Health Unit. A letter was sent to treating doctors on receipt of a notification, requesting additional information on cases. Cases identified by the treating doctors as newly acquired were followed up by telephone. RESULTS: There were 295 notifications of hepatitis B in the period, of which three were newly acquired infections. Only one of these three cases was identified through enhanced surveillance. Information on ethnicity was obtained. CONCLUSIONS: This enhanced surveillance system is of limited value as an ongoing process. We recommend that it be undertaken periodically to monitor the epidemiology of the disease.
