If Australia is to successfully eliminate hepatitis B as a public health threat, it will need to enhance the chronic hepatitis B (CHB) care cascade. This study used a Markov model to assess the impact, cost and cost-effectiveness of scaling up CHB diagnosis, linkage to care and treatment to reach national and international elimination targets for hepatitis B in Australia. Compared to continued current trends, the model calculated the difference in care cascade projection, disability-adjusted life years (DALYs), costs and the incremental cost-effectiveness ratio (ICER), of scaling up CHB diagnosis, linkage to care and treatment to reach: (a) Australia's 2022 national targets and (b) the WHO's 2030 global targets. Achieving the national and WHO targets had ICERs of A$13 435 (A$10 236-A$21 165) and A$14 482 (A$13 031-A$25 641) per DALY averted between 2016 and 2030 in Australia, respectively. However, this excluded implementation and demand generation costs. The ICER for the National Strategy and WHO Strategy remained under A$50 000 per DALY averted if Australia spent up to A$328 or A$538 million, respectively, per annum (for 2016-2030) on implementation and demand generation activities. Sensitivity analysis showed that cost-effectiveness was predominately driven by the cost of CHB treatment and influenced by disease progression rates. Hence for Australia to reach the National Hepatitis B Strategy 2022 targets and WHO Strategy 2030 targets, it requires an improvement in the CHB care cascade. We estimated it is cost-effective to spend up to A$328 million or A$538 million per year to reach the National and WHO Strategy targets, respectively., (© 2019 John Wiley & Sons Ltd.)

Background and Objectives: In Australia, over a third of individuals living with chronic hepatitis B (CHB) remain undiagnosed. Evidence suggests general practitioners (GPs) can be uncertain regarding whom to test. The aim of this study was to evaluate an educational resource for improving GPs' knowledge about whom to test for CHB., Method: Following a 2014 baseline survey that identified gaps in CHB knowledge among GPs in Victoria, an educational resource package was developed. Using a follow-up survey, the resource was evaluated by comparing the before-and-after CHB-related knowledge., Results: Sixty-five GPs responded to both the baseline and follow-up survey. Their knowledge of populations at high risk of CHB who require testing was significantly greater following the intervention than at baseline., Discussion: Concise, clear and practical resources can support GPs when identifying whom to test for hepatitis B.

Background: Passive surveillance is the principal method of sexually transmitted infection (STI) and blood-borne virus (BBV) surveillance in Australia whereby positive cases of select STIs and BBVs are notified to the state and territory health departments. A major limitation of passive surveillance is that it only collects information on positive cases and notifications are heavily dependent on testing patterns. Denominator testing data are important in the interpretation of notifications., Objective: The aim of this study is to establish a national pathology laboratory surveillance system, part of a larger national sentinel surveillance system called ACCESS (the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance). ACCESS is designed to utilize denominator testing data to understand trends in case reporting and monitor the uptake and outcomes of testing for STIs and BBVs., Methods: ACCESS involves a range of clinical sites and pathology laboratories, each with a separate method of recruitment, data extraction, and data processing. This paper includes pathology laboratory sites only. First established in 2007 for chlamydia only, ACCESS expanded in 2012 to capture all diagnostic and clinical monitoring tests for STIs and BBVs, initially from pathology laboratories in New South Wales and Victoria, Australia, to at least one public and one private pathology laboratory in all Australian states and territories in 2016. The pathology laboratory sentinel surveillance system incorporates a longitudinal cohort design whereby all diagnostic and clinical monitoring tests for STIs and BBVs are collated from participating pathology laboratories in a line-listed format. An anonymous, unique identifier will be created to link patient data within and between participating pathology laboratory databases and to clinical services databases. Using electronically extracted, line-listed data, several indicators for each STI and BBV can be calculated, including the number of tests, unique number of individuals tested and retested, test yield, positivity, and incidence., Results: To date, over 20 million STI and BBV laboratory test records have been extracted for analysis for surveillance monitoring nationally. Recruitment of laboratories is ongoing to ensure appropriate coverage for each state and territory; reporting of indicators will occur in 2019 with publication to follow., Conclusions: The ACCESS pathology laboratory sentinel surveillance network is a unique surveillance system that collects data on diagnostic testing, management, and care for and of STIs and BBVs. It complements the ACCESS clinical network and enhances Australia's capacity to respond to STIs and BBVs., International Registered Report Identifier (irrid): DERR1-10.2196/13625., (©Caroline van Gemert, Rebecca Guy, Mark Stoove, Wayne Dimech, Carol El-Hayek, Jason Asselin, Clarissa Moreira, Long Nguyen, Denton Callander, Douglas Boyle, Basil Donovan, Margaret Hellard.

Background A priority area in the 2016 Victorian Hepatitis B Strategy is to increase diagnostic testing. This study describes hepatitis B testing and positivity trends in Victoria between 2011 and 2016 using data from a national laboratory sentinel surveillance system., Methods: Line-listed diagnostic and monitoring hepatitis B testing data among Victorian individuals were collated from six laboratories participating in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) of sexually transmissible infections and blood-borne viruses. Diagnostic tests included hepatitis B surface antigen (HBsAg)-only tests and guideline-based hepatitis B tests (defined as a single test event for HBsAg, hepatitis B surface antibody and hepatitis B core antibody). Using available data, the outcomes of testing and/or infection were further classified. Measures reported include the total number of HBsAg and guideline-based tests conducted and the proportion positive, classified as either HBsAg positive or chronic hepatitis B infection., Results: The number of HBsAg tests decreased slightly each year between 2011 and 2016 (from 91043 in 2011 to 79664 in 2016; P < 0.001), whereas the number of guideline-based hepatitis B tests increased (from 8732 in 2011 to 16085 in 2016; P <0.001). The proportion of individuals classified as having chronic infection decreased from 25% in 2011 to 7% in 2016, whereas the proportion classified as susceptible and immune due to vaccination increased (from 29% to 39%, and from 27% to 34%, respectively; P < 0.001)., Conclusions: The study findings indicate an increased uptake of guideline-based hepatitis B testing. The ongoing collection of testing data can help monitor progress towards implementation of the Victorian Hepatitis B Strategy.

Background: New biomedical prevention interventions make the control or elimination of some blood-borne viruses (BBVs) and sexually transmissible infections (STIs) increasingly feasible. In response, the World Health Organization and governments around the world have established elimination targets and associated timelines. To monitor progress toward such targets, enhanced systems of data collection are required. This paper describes the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS)., Objective: This study aims to establish a national surveillance network designed to monitor public health outcomes and evaluate the impact of strategies aimed at controlling BBVs and STIs., Methods: ACCESS is a sentinel surveillance system comprising health services (sexual health clinics, general practice clinics, drug and alcohol services, community-led testing services, and hospital outpatient clinics) and pathology laboratories in each of Australia's 8 states and territories. Scoping was undertaken in each jurisdiction to identify sites that provide a significant volume of testing or management of BBVs or STIs or to see populations with particular risks for these infections ("priority populations"). Nationally, we identified 115 health services and 24 pathology laboratories as relevant to BBVs or STIs; purposive sampling was undertaken. As of March 2018, we had recruited 92.0% (104/113) of health services and 71% (17/24) of laboratories among those identified as relevant to ACCESS. ACCESS is based on the regular and automated extraction of deidentified patient data using specialized software called GRHANITE, which creates an anonymous unique identifier from patient details. This identifier allows anonymous linkage between and within participating sites, creating a national cohort to facilitate epidemiological monitoring and the evaluation of clinical and public health interventions., Results: Between 2009 and 2017, 1,171,658 individual patients attended a health service participating in ACCESS network comprising 7,992,241 consultations. Regarding those with unique BBV and STI-related health needs, ACCESS captured data on 366,441 young heterosexuals, 96,985 gay and bisexual men, and 21,598 people living with HIV., Conclusions: ACCESS is a unique system with the ability to track efforts to control STIs and BBVs-including through the calculation of powerful epidemiological indicators-by identifying response gaps and facilitating the evaluation of programs and interventions. By anonymously linking patients between and within services and over time, ACCESS has exciting potential as a research and evaluation platform. Establishing a national health surveillance system requires close partnerships across the research, government, community, health, and technology sectors., International Registered Report Identifier (irrid): DERR1-10.2196/11028., (©Denton Callander, Clarissa Moreira, Carol El-Hayek, Jason Asselin, Caroline van Gemert, Lucy Watchirs Smith, Long Nguyen, Wayne Dimech, Douglas IR Boyle, Basil Donovan, Mark Stoové, Margaret Hellard, Rebecca Guy.

Introduction: Students comprised the majority of early cases of influenza A(H1N1)pdm09 in Melbourne, Australia. Students and school settings were targeted for public health interventions following the emergence of pH1N1. This study was conducted to describe changes in social contacts among the earliest confirmed student cases of pH1N1 in Melbourne, Australia, to inform future pandemic control policy and explore transmission model assumptions., Methods: A retrospective cross-sectional behavioural study of student cases with laboratory-confirmed pH1N1 between 28 April and 3 June 2009 was conducted in 2009. Demographics, symptom onset dates and detailed information on regular and additional extracurricular activities were collected. Summary measures for activities were calculated, including median group size and median number of close contacts and attendance during the students' exposure and infectious periods or during school closures. A multivariable model was used to assess associations between rates of participation in extracurricular activities and both school closures and students' infectious periods., Results: Among 162 eligible cases, 99 students participated. Students reported social contact in both curricular and extra-curricular activities. Group size and total number of close contacts varied. While participation in activities decreased during the students' infectious periods and during school closures, social contact was common during periods when isolation was advised and during school closures., Discussion: This study demonstrates the potential central role of young people in pandemic disease transmission given the level of non-adherence to prevention and control measures. These finding have public health implications for both informing modelling estimates of future pandemics and targeting prevention and control strategies to young people., ((c) 2018 The authors; licensee World Health Organization.)

Background: Syndromic management of sexually transmissible infections is commonly used in resource-poor settings for the management of common STIs; abnormal vaginal discharge (AVD) flowcharts are used to identify and treat cervical infection including Neisseria gonorrhoea and Chlamydia trachomatis. A systematic review and meta-analysis was undertaken to measure the diagnostic test performance of AVD flowcharts, including both World Health Organization (WHO)- and locally-adapted AVD flowcharts., Methods: A systematic search of multiple electronic databases was conducted to locate eligible studies published between 1991 and 2014. Flowcharts were categorised into one of 14 types based on: 1) use of WHO guidelines or locally-adapted versions; 2) use of risk assessment, clinical examination or both; and 3) symptomatic entry. Summary diagnostic performance measures calculated included summary sensitivity, summary specificity and diagnostic odds ratio., Results: Thirty-six studies, including data on 99 flowcharts, were included in the review. Summary sensitivity estimates for WHO flowcharts ranged from 41.2 to 43.6%, and for locally adapted flowcharts from 39.5 to 74.8%. Locally adapted flowcharts performed slightly better than the WHO flowcharts. A difference in performance was not observed between use of risk assessment or clinical examination. The AVD flowchart performed slightly better when it was not restricted to symptomatic women only., Conclusions: There was considerable variation in the performance of the AVD flowchart but overall it was a poor diagnostic tool regardless of whether risk assessment or clinical examination was included, or whether the flowchart was WHO or locally developed. Many women were treated unnecessarily and many women with cervical infection were not detected. We caution against their continued use for management of cervical infection.

Background: More than one-third of people living with chronic hepatitis B virus (HBV) in Australia have not been diagnosed. The aim of this study was to assess general practitioners' (GPs') knowledge and practices regarding chronic HBV diagnosis, and identify opportunities to improve testing rates., Methods: A cross-sectional survey was conducted with GPs working in Victoria, Australia. Statistically significant adjusted odds ratios for high knowledge, and ordering two or more HBV tests per week were calculated., Results: Of 1000 GPs who were invited to participate, 232 completed the survey. Chronic HBV knowledge, use of interpreters, and awareness of HBV testing guidelines were low. Chronic HBV knowledge and testing were associated with age and graduation from a medical school outside Australia. Testing was also associated with gender., Discussion: This study identified gaps in GPs' knowledge about chronic hepatitis. Several barriers to improving testing rates among at-risk populations were identified. We recommend revision of the guidelines for prevention in general practice, and educational activities to improve knowledge of at-risk populations for chronic HBV in Australia.

People engaging in transactional sex are considered a key population for HIV prevention. Prior quantitative surveys demonstrated that behaviorally bisexual men in Vientiane, Laos commonly transact sex. In 2013, we conducted a qualitative study to explore behaviorally bisexual men's experience, motivations, and perceptions related to transactional sex in Vientiane. Behaviorally bisexual men were recruited from bars, nightclubs, and dormitories for five focus group discussions (FGDs) and 11 in-depth interviews (n = 31). Additionally, young women were recruited from a university, garment factory, and nightclub for four FGDs (n = 22). Transcripts were translated and thematically coded. Bisexual male participants most commonly described being paid for sex by male-to-female transgender people and buying sex from women. Both male and female participants reported that older, single women pay younger men for sex. Negotiation and direction of sexual transactions are influenced by age, attraction, and wealth. Common motivations for selling sex included the need for money to support family or fund school fees, material gain, or physical pleasure. Transactional sex was often opportunistic. Some behaviorally bisexual men reported selling sex in order to pay another more desirable sex partner or to buy gifts for their regular sex partner. Participants perceived high risk associated with intercourse with female sex workers but not with other transactional sex partners. Health interventions are needed to improve knowledge, risk perception, and health behaviors, but must recognize the diversity of transactional sex in Vientiane. Both physical and virtual settings may be appropriate for reaching behaviorally bisexual men and their partners.

Background: Chlamydia, caused by Chlamydia trachomatis, is the most common reportable infection in many developed countries. Testing, treatment, and partner notification (PN) are key strategies for chlamydia control. In 2008 the Let Them Know (LTK) PN website was established, which provided means for people to send anonymous PN messages by text messaging (short message service, SMS), email, or letter., Objective: We evaluated PN practices among Australian family planning clinicians following chlamydia diagnosis and assessed how often clinicians refer their patients to the LTK website., Methods: A mixed methods approach included a Web-based cross-sectional survey of Australian family planning clinicians to examine PN attitudes and practices and focus groups to explore the context of LTK website use., Results: Between May 2012 and June 2012, all clinicians from 29 different family planning services (n=212) were invited to complete the survey, and 164 participated (response rate=77.4%); of the clinicians, 96.3% (158/164) were females, 56.1% (92/164) nurses, and 43.9% (72/164) doctors. More than half (62.2%, 92/148) agreed that PN was primarily the client's responsibility; however, 93.2% (138/148) agreed it was the clinician's responsibility to support the client in informing their partners by providing information or access to resources. Almost half (49.4%, 76/154) of the clinicians said that they always or usually referred clients to the LTK website, with variation across clinics in Australian states and territories (0%-77%). Eleven focus groups among 70 clinicians at 11 family planning services found that the LTK website had been integrated into routine practice; that it was particularly useful for clients who found it difficult to contact partners; and that the LTK letters and fact sheets were useful. However, many clinicians were not aware of the website and noted a lack of internal clinic training about LTK., Conclusions: The LTK website has become an important PN tool for family planning clinicians. The variation in referral of patients to the LTK website and lack of awareness among some clinicians suggest further promotion of the website, PN training, and clinic protocols are warranted.

Background: It is estimated that over 40 % of the 218,000 people with chronic hepatitis B (CHB) in Australia in 2011 are undiagnosed. A disproportionate number of those with undiagnosed infection were born in the Asia-Pacific region. Undiagnosed CHB can lead to ongoing transmission and late diagnosis limits opportunities to prevent progression to hepatocellular carcinoma (HCC) and cirrhosis. Strategies are needed to increase testing for hepatitis B virus (HBV) (including culturally and linguistically diverse communities, Aboriginal and/or Torres Strait Islander (Indigenous) people and people who inject drugs). General practitioners (GPs) have a vital role in increasing HBV testing and the timely diagnosis CHB. This paper describes the impact of a GP-based screening intervention to improve CHB diagnosis among priority populations in Melbourne, Australia., Methods: A non-randomised, pre-post intervention study was conducted between 2012 and 2013 with three general practices in Melbourne, Australia. Using clinic electronic health records three priority populations known to be at increased CHB risk in Australia (1: Asian-born patients or patients of Asian ethnicity living in Australia; 2: Indigenous people; or 3): people with a history of injecting drugs were identified and their HBV status recorded. A random sample were then invited to attend their GP for HBV testing and/or vaccination. Baseline and follow-up electronic data collection identified patients that subsequently had a consultation and HBV screening test and/or vaccination., Results: From a total of 33,297 active patients, 2674 (8 %) were identified as a priority population at baseline; 2275 (85.1 %) of these patients had unknown HBV status from which 338 (14.0 %) were randomly sampled. One-fifth (n = 73, 21.6 %) of sampled patients subsequently had a GP consultation during the study period; only four people (5.5 %) were subsequently tested for HBV (CHB detected in n = 1) and none were vaccinated against HBV., Conclusion: CHB infection is an important long-term health issue in Australia and strategies to increase appropriate and timely testing are required. The study was effective at identifying whether Asian-born patients and patients of Asian had been tested or vaccinated for HBV; however the intervention was not effective at increasing HBV testing.

Unlabelled: Background Transactional sex may increase risk of HIV and sexually transmissible infections (STIs). In Laos, men who have sex with men are disproportionately affected by HIV, and bisexual behaviour among men is relatively common. The occurrence of transactional sex among behaviourally bisexual men in Vientiane, Laos was explored., Methods: In 2010, behaviourally bisexual men were recruited through enhanced snowball sampling to complete a behavioural survey. Reports of transactional sex partners (anal/vaginal sex) in the previous year, by direction of payment and partner gender, is described., Results: Of 88 participating behaviourally bisexual men (median age 22 years), 17 (19%) reported only selling sex, eight (9%) reported only paying for sex and nine (10%) reported both selling and paying for sex. Men reporting any transactional sex reported a median of four transactional sex partners and reported a higher number of total sex partners in the previous 12 months (median: 18.5 partners) than men reporting no transactional sex partners (median: 6 partners). Of 26 men who reported selling sex, 15 (58%) were paid by females, 15 (58%) were paid by males and 14 (55%) were paid by transgender sex partner(s); 11 (42%) reported consistent condom use (CCU) when selling sex. Of 17 men who reported paying for sex, 13 (76%) paid females, six (35%) paid males and two (12%) paid transgender partner(s); eight (47%) reported CCU when paying for sex., Conclusions: Young behaviourally bisexual men engaging in transactional sex may be at increased risk of HIV and STIs. Prevention interventions should consider the transient and informal nature of transactional sex in this population.

Background: Call centres can improve the effectiveness of health services by helping reduce access barriers associated with stigma and geography. This project aimed to develop and pilot a standardised evaluation framework to assess Marie Stopes International reproductive health call centres., Methods: Consultations were held with staff from the 14 existing international call centres to gauge current monitoring and evaluation processes, identify gaps, and establish evaluation needs. The draft framework was then piloted in the Marie Stopes Mexico call centre using client and provider surveys, mystery callers and a review of call centre records., Results: A flexible framework was developed to allow call centres to measure the effectiveness of services offered. Nineteen indicators were developed to assess access, equity, quality and efficiency. The pilot found pre-defined ranges for indicators of access were not appropriate for a high-functioning call centre that was already achieving nearly 100% compliance. Several indicators could not be measured due to a lack of routine data collection systems., Conclusions: A standardised evaluation framework will allow comparisons over time and between call centres in different countries. Future assessments could be improved by establishing routine, reliable data collection systems prior to framework implementation. This is one of the first attempts to standardise the evaluation of a reproductive health call centre and establishes a method by which they can be monitored, and thus improved, over time.

Despite high sexually transmitted infection (STI) prevalence in the Pacific, there are limited data on STIs and risk among men who have sex with men (MSM) and transgender people (TG). In 2011, an Integrated Bio-Behavioural Survey recruited self-identified MSM and TG in Port Vila, Vanuatu. Descriptive findings were stratified by sexuality. Among 28 (55%) MSM and 23 (45%) TG, recent anal sex with male partners was more common among MSM (94% vs 71%; P < 0.1), including with casual (47% vs 35%), regular (59% vs 29%) and paying partners (28% vs 12%). MSM more commonly reported lifetime (P < 0.01) and recent sex with female partners (P < 0.01). Reported condom use with any partner type was low. More MSM (35%) than TG (24%) were diagnosed with an STI; previous treatment-seeking behaviour when symptomatic was lower among TG (P < 0.1). Tailored strategies acknowledging differences between MSM and TG are required to reduce STI vulnerability in Vanuatu.

Objective: Australia is an increasingly multicultural nation. Never before has the dental workforce been exposed to such language, cultural, religious and ethnic diversity. There is evidence that refugee and migrant children experience significantly poorer oral health than the nonmigrant population. However, little is known about the oral health knowledge, practices and beliefs of parents with young children from refugee and migrant backgrounds. The aim of this study was to identify the sociocultural influences on child oral health in these communities., Design: Participatory and qualitative research methods were utilised. Partnerships were established with community agencies representing migrants from Iraq, Lebanon and Pakistan. Focus group discussions and semi-structured interviews were conducted with community members. Qualitative data were analysed thematically, combining focus group and interview data., Results: Over 100 women participated in focus groups (n = 11) and semi-structured interviews (n = 7). Key findings included the knowledge, beliefs and practices concerning: caries risk factors, oral health practices and oral health literacy. Despite mothers' knowledge of the major causes of poor oral health - dietary changes, confusion about child oral hygiene practices and limited oral health literacy all influenced child oral health outcomes., Conclusion: This culturally competent qualitative study explores the sociocultural factors influencing child oral health in refugee and migrant communities. Understanding and acknowledging these factors are a prerequisite to determining where and how to intervene to improve oral health. Furthermore, it has implications for both dental and non-dental health professionals working to reduce health inequalities within such communities.

Behaviorally bisexual men (BBM) in Vientiane, Laos report high-risk sexual behaviors. We explore settings for meeting sex partners and associated risk behaviors among BBM in Laos. BBM and their sexual partners were recruited in Vientiane Capital using modified snowball sampling (2010). Settings for usually meeting sex partners and associations with risk behaviors were assessed. Among 88 BBM, the most common settings for men meeting male, kathoey, and female sex partners were private residences (48%, 37%, 51%, respectively) and hospitality settings (39%, 31%, 40%, respectively). Hospitality settings were more commonly reported by heterosexual-identifying BBM, and private residences more commonly reported by bisexual/homosexual-identifying BBM. Inconsistent condom use was high across partners and settings. Meeting partners in hospitality settings was associated with reporting a high number of female sex partners and frequently drinking alcohol before sex. Our results suggest that targeted health promotion initiatives in bars, clubs, and beer-shops could reach a high proportion of high-risk bisexual men, particularly heterosexual-identifying BBM.

There are over 500-750 000 deaths per year because of hepatitis B virus (HBV)-related cirrhosis and liver cancer worldwide and the World Health Organization Western Pacific Region has some of the highest endemic levels of HBV in the world, particularly within China, South East Asia and Pacific Island Countries and Territories (PICT). The PICT have unique ethnic diversity and a very high prevalence of smoking and metabolic syndrome, both important risk factors for liver fibrosis and liver cancer. However, in contrast to many Asian countries, there is little published data on HBV prevalence and related liver disease burden in PICT. In this review, the available published literature and World Health Organization data for HBV prevalence and related liver disease and liver cancer burden in PICT is outlined, and unmet needs for improving HBV prevention and control in the region are highlighted., (© 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.)

There is insufficient data on sexually transmitted infections (STI) and related behaviours among key populations, including female sex workers (FSW), in the Pacific region. Using respondent driven sampling, we conducted an integrated bio-behavioural survey with FSW in Vanuatu (aged ≥18 years) to investigate risk behaviours associations with Chlamydia trachomatis (CT). Weighted population estimates and correlates of CT infection were calculated. Among 149 FSW, prevalence of CT was 36 % (95 % CI 26-48 %). Few FSW reported consistent condom use with recent transactional sex partners (TSP) (8 %; 95 % CI 2-13 %). CT infection was positively associated with increasing number of TSP (adjusted odds ratio [AOR] 1.1; 95 % CI 1.0-1.2) and group sex (AOR 2.9; 95 % CI 1.1-8.2). CT was negatively associated with increasing age of first sex (AOR 0.6; 95 % CI 0.5-0.9) and previous STI treatment (AOR 0.1; 95 % CI 0.0-0.4). A comprehensive public health strategy for prevention and treatment of STI among FSW, incorporating community empowerment strategies, FSW-targeted health services and periodic presumptive treatment, is urgently needed in Vanuatu.

Unlabelled: Background Clinical guidelines commonly recommend annual chlamydia (Chlamydia trachomatis) testing in young people. General practice (GP) clinics can play an important role in annual testing, as a high proportion of young people attend these clinics annually; however, little is known about the timing of attendance and testing in this setting., Methods: The Australian Collaboration for Coordinated Enhanced Sentinel Surveillance of Sexually Transmitted Infections and Blood-Borne Viruses system extracted consultation and pathology data on 16-29-year-olds attending 25 GP clinics in 2007-10. We calculated the proportion of individuals with an initial negative test that reattended at 12 months (±3 months) and retested at 12 months (±3 months). Individuals with an initial positive test were excluded, as guidelines recommend retesting at 3 months., Results: Among 3852 individuals who had an initial negative test, 2201 (57.1%) reattended at ~12 months; reattendance was higher among females (60.8%) than males (44.1%; P<0.001) and higher among 16-19-year-olds (64.2%) than 25-29-year-olds (50.8%; P<0.001). Of 2201 individuals who reattended at 12 months, 377 had a chlamydia test (retesting rate of 9.8%); retesting was higher among females (10.8%) than males (6.1%; P<0.01) and higher among 16-19-year-olds (13.3%) than 25-29-year-olds (7.5%; P<0.001)., Conclusion: Although over half of young people reattended their GP clinic ~1 year after a negative chlamydia baseline test, only 9.8% were retested at this visit. Strategies are needed to promote regular attendance and testing to both patients and clinicians.

Background: Chlamydial infection is the most common notifiable disease in Australia, Europe and the US. Australian notifications of chlamydia rose four-fold from 20,274 cases in 2002 to 80,846 cases in 2011; the majority of cases were among young people aged less than 29 years. Along with test positivity rates, an understanding of the number of tests performed and the demographics of individuals being tested are key epidemiological indicators. The ACCESS Laboratory Network was established in 2008 to address this issue., Methods: The ACCESS Laboratory Network collected chlamydia testing data from 15 laboratories around Australia over a three-year period using data extraction software. All chlamydia testing data from participating laboratories were extracted from the laboratory information system; patient identifiers converted to a unique, non-reversible code and de-identified data sent to a single database. Analysis of data by anatomical site included all specimens, but in age and sex specific analysis, only one testing episode was counted., Results: From 2008 to 2010 a total of 628,295 chlamydia tests were referred to the 15 laboratories. Of the 592,626 individual episodes presenting for testing, 70% were from female and 30% from male patients. In female patients, chlamydia positivity rate was 6.4% overall; the highest rate in 14 year olds (14.3%). In male patients, the chlamydia positivity rate was 9.4% overall; the highest in 19 year olds (16.5%). The most common sample type was urine (57%). In 3.2% of testing episodes, multiple anatomical sites were sampled. Urethral swabs gave the highest positivity rate for all anatomical sites in both female (7.7%) and male patients (14%), followed by urine (7.6% and 9.4%, respectively) and eye (6.3% and 7.9%, respectively)., Conclusions: The ACCESS Laboratory Network data are unique in both number and scope and are representative of chlamydia testing in both general practice and high-risk clinics. The findings from these data highlight much lower levels of testing in young people aged 20 years or less; in particular female patients aged less than 16 years, despite being the group with the highest positivity rate. Strategies are needed to increase the uptake of testing in this high-risk group.

Objectives: Traditional assessment of research quality addresses aspects of scientific rigor, however, ensuring barriers to participation by people of different cultural backgrounds are addressed requires cultural competence. The aim of this research was to assess the cultural competence of oral health research conducted with migrant children., Methods: A protocol was developed with explicit inclusion and exclusion criteria. Electronic databases were searched from 1995 to 2009. Each study was assessed for cultural competence using the assessment criteria and a template developed as a proof-of-concept approach., Results: Of the 2059 articles identified, 58 met inclusion criteria (n = 48 studies). There were four (8.3%) cohort studies, five (10.4%) intervention studies, 37 (77.1%) quantitative cross-sectional studies, and two (4.2%) were qualitative studies. Overall, migrant children had worse oral health outcomes in all studies compared with their host-country counterparts. All studies rated poorly in the cultural competence assessment., Conclusions: Appropriate inclusion of all potentially vulnerable groups in research will result in better estimates and understandings of oral health, and more reliable recommendations for prevention and management., (© 2013 John Wiley & Sons A/S.

Men who have sex with both men and women (behaviorally bisexual men) may be at increased risk of HIV acquisition and transmission due to risky sexual behaviors. We recruited a sexual network comprised of behaviorally bisexual men and their sexual partners in Vientiane, Lao PDR in 2010 to inform our understanding of the potential for HIV transmission among heterosexual, homosexual, and bisexual networks. Participants completed a sexual behavior questionnaire and referred < 5 sexual partners. A total of 298 people were recruited, including 63 behaviorally bisexual men. Behaviorally bisexual men reported riskier sexual behaviors (number of sexual partners in the previous 12 months and consistent condom use) than behaviorally homosexual and heterosexual men. Using social network diagrammatic representation, heterosexual, homosexual, and bisexual networks are shown to be interlinked. This study demonstrates that behaviorally bisexual men are potential key drivers of HIV epidemics and require a targeted approach to sexual health promotion.

Background: Injecting drug use (IDU) is a growing concern in Tanzania compounded by reports of high-risk injecting and sexual risk behaviours among people who inject drugs (PWID). These behaviours have implications for transmission of blood-borne viruses, including HIV and hepatitis C (HCV)., Methods: We recruited 267 PWID (87% male) from Temeke District, Dar-es-Salaam through snowball and targeted sampling. A behavioural survey was administered alongside repeated rapid HIV and HCV antibody testing. HIV and HCV prevalence estimates with 95% confidence intervals (CIs) were calculated., Results: Among PWID, 34.8% (95%CI 29.1-40.9) tested HIV positive (29.9% of males and 66.7% of females); 27.7% (95%CI 22.0-34.0) tested HCV antibody positive. Almost all (97%) participants were aware of HIV and 34% of HCV. 45% of male and 64% of female PWID reported a previous HIV test; only five (2%) PWID reported a previous HCV test. Of HIV and HCV positive tests, 73% and 99%, respectively, represented newly diagnosed infections., Conclusion: High prevalence of HIV and HCV were detected in this population of PWID. Rapid scale-up of targeted primary prevention and testing and treatment services for PWID in Tanzania is needed to prevent further transmission and consequent morbidities., (Copyright © 2012 Elsevier B.V.

Introduction and Aims: Young people are at high risk of alcohol-related harm and injury. This study assessed awareness of the 2009 Australian Guidelines to Reduce Health Risks from Drinking Alcohol, understanding of alcohol-related risks and drinking behaviours among young people., Design and Methods: We recruited participants (16-29 years) from a music festival in Melbourne, Australia, January 2010. Participants self-completed a risk behaviour questionnaire which included questions regarding the 2009 guidelines. Characteristics associated with awareness of the guidelines and accurate understanding of a 'safe' number of drinks to avoid long-term harm and injury (defined as a maximum of two drinks daily and four drinks on a single occasion, respectively) were examined using multivariable logistic regression., Results: Of 1381 participants, only 32% were aware of the 2009 guidelines, but the majority had an accurate understanding of the safe number of drinks to avoid long-term harm (74%) and injury (71%). Nonetheless, many reported drinking behaviour with risk of long-term harm (22%) or injury (54%). Participants with lower-risk drinking behaviours were more likely to have an accurate understanding of the safe number of drinks to avoid harm. Males and participants without post-high school education were significantly less likely to be aware of the guidelines and/or have an accurate understanding of alcohol-related risks (P < 0.05)., Discussion and Conclusions: Although raising awareness of alcohol-related risks may promote reduced alcohol consumption, many young people reported consuming alcohol at harmful levels despite having an accurate understanding of alcohol-related risks. Multiple approaches to reducing alcohol-related harm in young people should be considered., (© 2011 Australasian Professional Society on Alcohol and other Drugs.)

Dental caries is an extremely debilitating disease with lifelong consequences. In most developed countries significant oral health inequalities exist in disadvantaged communities, including refugee and migrant populations. Addressing these inequalities is becoming increasingly challenging as communities become more culturally diverse. An awareness of traditional oral health practices would enable the dental and broader health professions, to understand these differences and consequently better meet the needs of disadvantaged communities. The use of miswak is a common traditional oral hygiene practice used by a number of culturally diverse groups. Further research is required into the use and effectiveness of traditional oral health practices within developed countries. Such practices need to be understood, respected and incorporated within oral health care, policies and practices in order to reduce significant inequalities experienced in our communities. This commentary describes the current literature on miswak, its effectiveness and the implications for promoting oral health.

To examine intrahousehold secondary transmission of pandemic (H1N1) 2009 virus in households in Victoria, Australia, we conducted a retrospective cross-sectional study in late 2009. We randomly selected case-patients reported during May-June 2009 and their household contacts. Information collected included household characteristics, use of prevention and control measures, and signs and symptoms. Secondary cases were defined as influenza-like illness in household contacts within the specified period. Secondary transmission was identified for 18 of 122 susceptible household contacts. To identify independent predictors of secondary transmission, we developed a model. Risk factors were concurrent quarantine with the household index case-patient, and a protective factor was antiviral prophylaxis. These findings show that timely provision of antiviral prophylaxis to household contacts, particularly when household members are concurrently quarantined during implementation of pandemic management strategies, delays or contains community transmission of pandemic (H1N1) 2009 virus.

Maternal health across Papua New Guinea (PNG) is of extreme public health concern. In response, the National Department of Health explicitly prioritized improving maternal, neonatal and child health services, envisaging increased collaboration between the formal health system and community-based initiatives as one method for achieving this. This study examined the patterns of formal and non-formal service utilization during pregnancy and childbirth in one province. We analysed the activity database of the East Sepik Women and Children's Health Project's Village Health Volunteer (VHV) program, an informal health service in East Sepik Province of PNG, estimating VHV activity and coverage for two maternal health care services (first antenatal care visit and VHV-attended deliveries) and comparing these to the volume and estimated coverage of these services delivered by the formal health system in East Sepik over the years 2007 to 2010. We found a significant increase in women's utilization of VHVs for first antenatal care and for an attended delivery. Reported coverage of these services delivered by the formal health service declined or at best remained static over the same time period. Our data cannot illuminate the causes of an apparent and highly concerning decline in health facility usage for assisted delivery, nor the reasons for increased usage of VHVs. The factors contributing to these trends in service provision require urgent study, to improve our understanding of the drivers of utilization of critical maternal health services. Our study demonstrates that VHVs deliver a substantial proportion of maternal health services in East Sepik. This finding alone highlights the importance of considering this cadre when planning health service improvements and suggests that a national VHV policy that builds on the work of the National Health Plan in defining the most appropriate role for VHVs in maternal health care is long overdue.

Background: The Australian Government launched a mass media campaign in 2009 to raise awareness of the harms and costs associated risky drinking among young Australians. The aim of this study was to assess if young people attending a music festival who report frequent risky single occasions of drinking (RSOD) recognise the key message of the campaign, "Binge drinking can lead to injuries and regrets", compared to young people who report less frequent RSOD., Methods: A cross-sectional behavioural survey of young people (aged 16-29 years) attending a music festival in Melbourne, Australia, was conducted in January 2009. We collected basic demographics, information on alcohol and other drug use and sexual health and behaviour during the previous 12 months, and measured recognition of the Australian National Binge Drinking Campaign key message. We calculated the odds of recognition of the key slogan of the Australian National Binge Drinking Campaign among participants who reported frequent RSOD (defined as reported weekly or more frequent RSOD during the previous 12 months) compared to participants who reported less frequent RSOD., Results: Overall, three-quarters (74.7%) of 1072 participants included in this analysis recognised the campaign message. In the adjusted analysis, those reporting frequent RSOD had significantly lower odds of recognising the campaign message compared to those not reporting frequent RSOD (OR 0.7, 95% CI 0.5-0.9), whilst females had significantly greater odds of recognising the campaign message compared to males (OR 1.8, 95% CI 1.4-2.1)., Conclusions: Whilst a high proportion of the target group recognised the campaign, our analysis suggests that participants that reported frequent RSOD - and thus the most important group to target - had statistically significantly lower odds of recognising the campaign message.
