Background: The first mpox case was reported in May 2022 in Australia. Most cases have been diagnosed in men who have sex with men (MSM). This study aimed to examine community understanding of mpox, attitudes towards vaccination, and potential changes in sexual practices surrounding the mpox outbreak among MSM and transgender people in Victoria, Australia. Methods: Participants were recruited from sexual health clinics and communities in Victoria, Australia, in August–October 2022. Participants were asked about their understanding and knowledge of mpox, vaccination uptake and intentions to change sexual practices. Univariable and multivariable logistic regression was performed to examine the factors associated with mpox vaccine uptake. Results: Most participants (97.8%, 525/537) had heard about mpox and 10.5% (55/525) knew someone who had had mpox. Of the 12 mpox knowledge questions, the median score of correct answers was 10 (IQR = 8–11) out of a maximum of 12. More than a third (36.6%, 191/522) had been vaccinated against mpox. MSM who had a good knowledge of mpox had the highest odds of receiving mpox vaccine compared with those who had poor knowledge (aOR = 4.05; 95% CI: 1.54–10.61). To prevent mpox, half reported they would reduce having sex with casual partners, stop having chemsex (used drugs for the purpose of sex), stop attending sex-on-premises-venues, and stop having group sex. A quarter reported they would increase condom use for anal sex. Conclusions: One-third of high-risk participants and a substantial proportion of participants intended to reduce or stop certain practices, which may explain the large reduction in mpox cases. We conducted a cross-sectional survey among gay, bisexual and other men who have sex with men and transgender people across Victoria in Australia to understand community understanding of mpox, attitudes towards vaccination, and potential changes in sexual practices due to the mpox outbreak. Most people were willing to reduce or stop high-risk sexual practices to prevent mpox. Individuals who were at higher risk of acquiring mpox were likely to have received their mpox vaccine.

Background: Outbreaks of hepatitis A are being reported more commonly among men who have sex with men (MSM) globally. Australia has also reported a sharp increase in the number of cases of hepatitis A in 2017. This study aimed to determine the level of immunity to hepatitis A among MSM attending a large urban sexual health clinic in Victoria in the lead up to recent outbreak.Methods: This was a retrospective audit of serological testing data from first-time MSM attendees at Melbourne Sexual Health Centre (MSHC) in Australia from 1 January 2012 to 31 December 2018. We determined the proportion of MSM who were tested and who had serological detection of hepatitis A IgG, stratified by age and calendar year. We used univariable and multivariable logistic regression to investigate factors associated with testing for and detection of hepatitis A IgG.Results: There were 16 609 first-time MSM attendees at MSHC over the 7-year period, of which 9718 (59%, 95% CI 58% to 60%) were tested for hepatitis A IgG. There was a 2% annual increase in the proportion of men tested (from 60% in 2012 to 69% in 2018; OR=1.02, 95% CI 1.00 to 1.03, p=0.025). Men born outside of Australia/New Zealand, and younger men <30 years had higher odds of being tested. Of those tested, 44% (n=4304, 95% CI 43% to 45%) had hepatitis A IgG detected at their first visit, with no change over time (OR=1.01, 95% CI 0.99 to 1.03, p=0.210). Detection of hepatitis A IgG was associated with being aged 30 years or older (adjusted OR=2.06, 95% CI 1.89 to 2.24, p<0.001) or being born overseas versus Australia/New Zealand (AOR=1.21, 95% CI 1.11 to 1.31, p<0.001).Conclusion: Hepatitis A immunity among MSM remains below the estimated 70% required to prevent outbreaks. Measures including increased testing and higher vaccination coverage are needed to prevent outbreaks and to limit the number of cases and deaths. [ABSTRACT FROM AUTHOR]

Objective: In 2017, there was an outbreak of invasive meningococcal disease (IMD) serogroup C among men who have sex with men (MSM) in Victoria, Australia. A government-funded free meningococcal (MenACWY) vaccination programme targeting all MSM living in Victoria was launched between December 2017 and December 2018. The aim of this study was to examine the vaccine uptake among MSM attending a sexual health clinic in Melbourne.Methods: This was a retrospective clinical audit of MSM attending the Melbourne Sexual Health Centre (MSHC) during the vaccination programme. We calculated the proportion of MSM who received the meningococcal vaccine on their first visit and at any time during the programme. We performed univariable and multivariable logistic regression to identify the factors associated with the vaccine uptake on the first visit.Results: Of the 10 370 MSM who attended MSHC, 55.5% received the vaccine on their first visit and 67.4% at any time during the programme. MSM had higher odds of receiving the vaccine on the first visit if they were aged 16-25 years (adjusted OR (aOR) 1.21; 95% CI 1.08 to 1.35) or 26-35 years (aOR 1.17; 95% CI 1.07 to 1.29) in comparison with MSM older than 35 years; were HIV-negative and not on pre-exposure prophylaxis (aOR 1.80; 95% CI 1.56 to 2.09); had more than four male partners in the last 12 months (aOR 1.16; 95% CI 1.06 to 1.27); had male partners only (aOR 2.24; 95% CI 1.96 to 2.55); or were born overseas (aOR 1.11; 95% CI 1.03 to 1.21).Conclusions: Two-thirds of the MSM attending a sexual health clinic received at least one dose of meningococcal vaccine. The vaccination programme coincided temporally with a dramatic reduction in the incidence of IMD. Vaccination should be further promoted among MSM and men who have sex with both men and women.

Background In urban Australia, the burden of shigellosis is either in returning travelers from shigellosis-endemic regions or in men who have sex with men (MSM). Here, we combine genomic data with comprehensive epidemiological data on sexual exposure and travel to describe the spread of multidrug-resistant Shigella lineages. Methods A population-level study of all cultured Shigella isolates in the state of Victoria, Australia, was undertaken from 1 January 2016 through 31 March 2018. Antimicrobial susceptibility testing, whole-genome sequencing, and bioinformatic analyses of 545 Shigella isolates were performed at the Microbiological Diagnostic Unit Public Health Laboratory. Risk factor data on travel and sexual exposure were collected through enhanced surveillance forms or by interviews. Results Rates of antimicrobial resistance were high, with 17.6% (95/541) and 50.6% (274/541) resistance to ciprofloxacin and azithromycin, respectively. There were strong associations between antimicrobial resistance, phylogeny, and epidemiology. Specifically, 2 major MSM-associated lineages were identified: a Shigella sonnei lineage (n = 159) and a Shigella flexneri 2a lineage (n = 105). Of concern, 147/159 (92.4%) of isolates within the S. sonnei MSM-associated lineage harbored mutations associated with reduced susceptibility to recommended oral antimicrobials: namely, azithromycin, trimethoprim-sulfamethoxazole, and ciprofloxacin. Long-read sequencing demonstrated global dissemination of multidrug-resistant plasmids across Shigella species and lineages, but predominantly associated with MSM isolates. Conclusions Our contemporary data highlight the ongoing public health threat posed by resistant Shigella , both in Australia and globally. Urgent multidisciplinary public health measures are required to interrupt transmission and prevent infection. [ABSTRACT FROM AUTHOR]

Objectives: All males and females attending the Melbourne Sexual Health Centre (MSHC) from August 2017 were asked whether they had had sex with a transgender or gender diverse (TGD) person using computer-assisted self-interviewing (CASI). We aimed to verify the self-reported responses via chart review. The secondary aim of this study was to identify whether having sex with a TGD person was associated with STI risk.Methods: This was a retrospective chart analysis of patients visiting MSHC between August and December 2017. Chart review was performed to verify the self-reported responses. Multivariable logistic regression was performed to examine the association between having sex with a TGD person and patients' characteristics and STI risk.Results: Of the 10 100 male and female consultations, the proportion who reported having sex with a TGD person was 111 (1.0%) and was higher among males (1.3%) than females (0.6%) (p=0.001). After chart review, we could verify 66.9% of the responses, more for males (75.2%) than females (45.2%) (p<0.001). Of the 6822 males, men aged ≥35 years (adjusted OR=2.2; 95% CI 1.1 to 4.1) were more likely to have sex with a TGD person compared with men aged ≤24 years, after adjusting for confounding factors. Sex with a TGD person was not associated with sexual orientation in males. Of the 3278 females, gay and bisexual females had 13.7-fold (95% CI 5.1 to 37.0) higher odds of having sex with a TGD person than heterosexual females. There was no association between chlamydia positivity and sex with a TGD person in both males and females.Conclusion: When a question on TGD partners is asked as part of routine sexual history using CASI, the majority of responses could be verified. TGD partners were most commonly reported among males. These findings underscore the value of asking patients about sex with TGD partners. [ABSTRACT FROM AUTHOR]

Background Non-occupational post-exposure prophylaxis (NPEP) is available to people with a potential risk for HIV exposure within the preceding 72h. We sought to determine if men who have sex with men (MSM) and receive NPEP had a significantly different risk profile (before the preceding 72h) from MSM not receiving NPEP. If this is the case, NPEP consultations may act as a cue for also discussing pre-exposure prophylaxis.Methods: We conducted a retrospective analysis to compare the demographic characteristics, sexual practices and clinical diagnoses of MSM who were NPEP users and those who were non-NPEP users attending Melbourne Sexual Health Centre from January 2008 to December 2014. Univariate and multivariate logistic regression models were used to examine the association between NPEP use and risk practices. Generalised estimating equations were used to adjust for within-individual correlations related to multiple visits of the same individual.Results: Of the 40395 MSM consultations included in the study, 1776 consultations (4%) were related to NPEP prescription. NPEP prescribing was associated with ever having injected drugs (adjusted odds ratio (AOR) 1.8, 95% confidence interval (CI): 1.4-2.3), sex with males only (AOR 1.9, 95% CI: 1.6-2.3), more than three male partners in the past 3 months (AOR 1.5, 95% CI: 1.4-1.7) and inconsistent condom use with these partners within the past 3 months (AOR 2.1, 95% CI: 1.9-2.4). Sex workers (AOR 0.6, 95% CI: 0.3-0.9), and men reporting sex overseas within the past 12 months (AOR 0.7, 95% CI: 0.6-0.8) were less likely to receive NPEP. MSM who used NPEP were more likely to test positive for any sexually transmissible infection (AOR 1.2, 95% CI: 1.0-1.4).Conclusions: MSM receiving NPEP generally had a higher risk profile than MSM not requesting NPEP, indicating that NPEP was used by MSM at higher risk for HIV. Therefore, consultations for NPEP may be an opportune time for also discussing pre-exposure prophylaxis for HIV. [ABSTRACT FROM AUTHOR]

The article discusses research which investigated age, risk practices and methods being used by men who have sex with men (MSM) in Australia to meet possible sexual partners. Topics explored include the administration of a questionnaire to MSM that attend Melbourne Sexual Health Centre (MSHC) in Victoria, the percentage of respondents that use the Internet and geosocial networking mobile applications such as Grindr, and the number of respondents with regular or casual sexual partners.

Background Rapid HIV testing is not permitted in Australia at the point of care. The authors evaluate the expected net effect of rapid HIV testing compared with standard serology diagnostic tests in terms of onward HIV transmission. Methods The authors used data for 174 men who had sex with men testing HIV-positive at the Melbourne Sexual Health Centre, Australia, in an agent-based mathematical model. Time of diagnosis is simulated according to conventional enzyme immunoassays or rapid HIV tests, with different window periods. The authors calculated the expected number of additional/averted transmissions due to missed or earlier diagnoses. Results Fourth generation rapid tests were simulated to miss ~2-3% of diagnoses compared with conventional fourth generation enzyme immunoassay tests. However, in the remaining 97-98% of cases the rapid test would result in earlier detection of HIV. Overall, the rapid test would reduce time to patients receiving results by a median of ∼12 days. Assuming no changes in testing rates, the introduction of rapid testing diagnostic technologies would prevent one in every 2000-5000 HIV transmissions compared with the conventional diagnostic test. Conclusions Rapid tests would have a marginal benefit in reducing HIV transmission between men compared with conventional tests under assumptions of no changes in testing frequencies.

The article discusses a study on the effectiveness of advertising for the TESTme sexually transmissible infection (STI) screening service for young people in rural areas in Victoria. Websites, a page on the social networking site Facebook and business cards were among the advertising used. Advertisements in newspapers, student diaries and short messages to mobile telephones were also used. The study showed that 20 young people found out about the service with the help of health professionals while six knew about it through the Melbourne Sexual Health Centre (MSHC) web page. The centre incurred 20,850 Australian dollars in total direct costs for advertising. The authors note that advertising STI health services should focus on referrals from other health services or health care websites.

The article discusses the results of a chlamydia testing program undertaken among 16-29 years old from the Loddon Mallee region of Victoria. Chlamydia prevalence was noted to be high in the study population that use an illicit drug and has a low condom usage. Many participants were found to have poor knowledge on STIs and low condom use. The study concluded that the findings highlight the need for intervention programs that combine both sexually transmissible infections (STI) testing and prevention programs.

Background: The aim of this study was to characterise the clinical features of adenovirus urethritis in men and to compare the frequency of these between heterosexual men and men who have sex with men (MSM).Methods: This was a review of the clinical and laboratory information from men diagnosed with PCR-confirmed adenovirus urethritis at the Melbourne Sexual Health Centre between January 2006 and April 2014.Results: 102 adenovirus urethritis cases were reported, among which 61 were heterosexual men and 41 MSM. Eighty-nine per cent (n=91) had signs of meatitis or conjunctivitis: 51% had meatitis only; 32% meatitis together with conjunctivitis and 6% with conjunctivitis only. The distribution of symptoms and signs was similar among heterosexual men and MSM (p values >0.1). Adenovirus was the sole pathogen found in 93% of cases, excluding gonorrhoea, chlamydia, Mycoplasma genitalium and herpes simplex virus. Only 37% had ≥5 polymorphs per high-power field from a urethral smear. Where samples were still available for adenoviral sequencing (n=20), all were subgroup D.Conclusions: The clinical features of adenovirus urethritis in men can be distinctive and aid diagnosis, distinguishing it from other treatable causes of male urethritis.

Background: Targeted chlamydia screening has been advocated to reduce chlamydia associated reproductive sequelae. General practitioners are well positioned to play a major role in chlamydia control. The primary aim of this pilot study was to measure the effect of offering an online sexual health assessment tool, Youth Check Your Risk, on chlamydia testing rates among young people attending general practices. The secondary aim was to test the acceptability of the tool among general practitioners and young people. Methods: General practitioners at three practices in Melbourne, Australia, referred patients aged 16 to 24 years to Youth Check Your Risk http://www.checkyourrisk.org.au for use post-consultation between March to October 2007. The proportion of young people tested for chlamydia before and during the implementation of the tool was compared. Acceptability was assessed through a structured interviewer-administered questionnaire with general practitioners, and anonymous online data provided by Youth Check Your Risk users. Results: The intervention did not result in any significant increases in the proportion of 16 to 24 year old males (2.7% to 3.0%) or females (6.3% to 6.4%) tested for chlamydia. A small increase in the proportion of 16 to 19 year old females tested was seen (4.1% to 7.2%). Of the 2997 patients seen during the intervention phase, 871 (29.1%) were referred to Youth Check Your Risk and 120 used it (13.8%). Major reasons for low referral rates reported by practitioners included lack of time, discomfort with raising the issue of testing, and difficulty in remembering to refer patients. Conclusion: Offering an online sexual risk assessment tool in general practice did not significantly increase the proportion of young people tested for chlamydia, with GPs identifying a number of barriers to referring young people to Youth Check Your Risk. Future interventions aimed at increasing chlamydia screening in general practice with the aid of an online risk assessment tool need to identify and overcome barriers to testing.

The article discusses a study which determined whether pelvic examinations change clinical management of women with asymptomatic chlamydia infection. The study analyzed records for women with asymptomatic chlamydia who underwent a pelvic examination at a sexual health clinic in Melbourne, Victoria from January 2006 to June 2007. Findings showed that of the 91 cases examined, 31 warranted examination, one woman had muco-purulent cervicitis and mild tenderness, and was treated for possible pelvic inflammatory disease. The study also suggested that pelvic examination will lead to changes in treatment for very few women diagnosed with asymptomatic chlamydia infection.

Background: Use of alcohol-containing mouthwash has been found to have an inhibitory effect against pharyngeal gonorrhoea. The aim of this study was to investigate the association between self-reported mouthwash use and pharyngeal gonorrhoea detection among men who have sex with men (MSM).Methods: A cross-sectional survey was conducted between March 23, 2015, and June 30, 2015 among MSM attending the Melbourne Sexual Health Centre in Australia. Men who have sex with men were invited to complete a short questionnaire on mouthwash use and they were also tested for pharyngeal gonorrhoea by nucleic acid amplification test. Multivariate logistic regression was performed to examine the association between mouthwash use and pharyngeal gonorrhoea detection.Results: Of the 823 MSM, pharyngeal gonorrhoea detection decreased significantly with increasing age group (≤24 years, 14.5%; 25-34 years, 10.7%; ≥35 years, 6.0%; ptrend = 0.003). The proportion reporting daily use of mouthwash increased significantly with increasing age group (from 10.1% to 14.5% to 19.8%; ptrend = 0.005). However, there was no significant association between pharyngeal gonorrhoea detection and daily use of mouthwash after adjusting for age, number of male sexual partners, human immunodeficiency virus status, and type of mouthwash use.Conclusions: Although the proportion of daily use of mouthwash increased with age, and pharyngeal gonorrhoea detection decreased with age, the association between self-reported mouthwash use and pharyngeal gonorrhoea detection by nucleic acid amplification test was not statistically significant.

Previous studies have examined sex workers' attitudes to work but not their levels of job satisfaction compared with other occupations. The job satisfaction levels and standards of living of sex workers in licensed brothels in Victoria were compared with Australian women. Responses to a questionnaire that included questions about sex work and their 'most likely alternative job.' Survey data was compared with identical questions from the Households, Income and Labour Dynamics in Australia Survey. A structured survey was undertaken with sex workers in Victoria attending a a sexual health service. Of the 112 sex workers who agreed to participate in the study, 85 (76%) completed the survey. The median years women had been working as sex workers was three (range 0.1-18). The main reasons women started sex work was because 'they needed the money' (69%), were attracted to the flexible hours (44%) or had a particular goal in mind (43%). The two biggest concerns women had about sex work were their safety (65%) and the risk of sexually transmitted infections (65%). When compared with the median job satisfaction scores of Australian women working in sex workers' 'most likely alternative jobs,' 50% of sex workers reported a higher median satisfaction score for sex work in relation to hours worked, 47% in relation to flexibility, 43% in relation to total pay, 26% in relation to job security, 19% in relation to the work itself, and 25% in relation to overall job satisfaction. Women reported that they primarily do sex work for financial gain although a significant minority prefer it to other work they would be likely to do. These results should be interpreted in the context that the presence of personality disorders that are common among sex workers were not measured in this study. [ABSTRACT FROM AUTHOR]

The article presents a study which shows that frequent screening may increase the detection of early asymptomatic syphilis on homosexual men with HIV. The study covers the HIV-positive men who have sex with men (MSM) who attend regular syphilis screening at the Melbourne Sexual Health Centre in Victoria from January 2007 to June 2008. The study also involves serology and polymerase chain reaction (PCR), in which the results were compared to the data from July 2005 to December 2006.

The article investigates the temporal associations between Trichomonas vaginalis (TV) diagnoses in women at a large urban sexual health clinic and a major Papanicolaou smear screening laboratory in Victoria, Australia with Pap smear screening rates and the introduction of nitroimidazole treatments. Diagnoses of TV at the Melbourne Sexual Health Center peaked in the 1950s at 20 percent to 30 percent and then rapidly declined through the 1960s and 1970s to below one percent in 1990. It suggests that the introduction of metronidazole was associated with a large reduction in TV among Victorian women in the 1960s.

The article determines the association between the collection technique from the pharynx and the detection rate of gonorrhea using culture in Victoria. The study shows that detection rate for pharyngeal gonorrhea is associated with which clinicians reported inducing a gag reflex. It notes that the technique for collecting swabs for pharyngeal gonorrhea is important in optimizing detection of gonorrhea.

The Victorian Government introduced a time-limited human papillomavirus (HPV) catch-up program for gay, bisexual, and other men who have sex with men (GBMSM) aged ≤ 26 years in 2017-2019. We conducted a retrospective observational study to examine the accuracy of the self-report of HPV vaccination status using computer-assisted self-interviewing versus their immunization history via electronic health records. We included GBMSM aged 23-30 years visiting the Melbourne Sexual Health Centre (MSHC) in 2020-2021 because they were age-eligible for the HPV catch-up program in Victoria, Australia. Individuals who were unsure about their vaccination status were categorized as 'unvaccinated'. Of the 1,786 eligible men, 1,665 men self-reported their HPV vaccination status: 48.8% ( n  = 812) vaccinated, 17.4% ( n  = 289) unvaccinated, and 33.9% ( n  = 564) unsure. Self-reported HPV vaccination had a sensitivity of 61.3% (95%CI: 58.3 to 64.2%; 661/1079), a specificity of 74.2% (95%CI: 70.5 to 77.7%; 435/586), a positive predictive value of 81.4% (95%CI: 78.6 to 84.0%; 661/812), a negative predictive value of 51.0% (95%CI: 47.6 to 54.4%; 435/853), and an accuracy of 52.6% (95%CI: 50.1 to 55.0%). Our results showed that only half of GBMSM know and report their HPV vaccination status correctly. Novel approaches such as digital vaccine passports may be useful for individuals to accurately report their vaccination status to guide accurate clinical decisions and management.

Introduction: The sexually transmitted infection chlamydia can cause significant complications, particularly among people with female reproductive organs. Optimal management includes timely and appropriate treatment, notifying and treating sexual partners, timely retesting for reinfection and detecting complications including pelvic inflammatory disease (PID). In Australia, mainstream primary care (general practice) is where most chlamydia infections are diagnosed, making it a key setting for optimising chlamydia management. High reinfection and low retesting rates suggest partner notification and retesting are not uniformly provided. The Management of Chlamydia Cases in Australia (MoCCA) study seeks to address gaps in chlamydia management in Australian general practice through implementing interventions shown to improve chlamydia management in specialist services. MoCCA will focus on improving retesting, partner management (including patient-delivered partner therapy) and PID diagnosis., Methods and Analysis: MoCCA is a non-randomised implementation and feasibility trial aiming to determine how best to implement interventions to support general practice in delivering best practice chlamydia management. Our method is guided by the Consolidated Framework for Implementation Research and the Normalisation Process Theory. MoCCA interventions include a website, flow charts, fact sheets, mailed specimen kits and autofills to streamline chlamydia consultation documentation. We aim to recruit 20 general practices across three Australian states (Victoria, New South Wales, Queensland) through which we will implement the interventions over 12-18 months. Mixed methods involving qualitative and quantitative data collection and analyses (observation, interviews, surveys) from staff and patients will be undertaken to explore our intervention implementation, acceptability and uptake. Deidentified general practice and laboratory data will be used to measure pre-post chlamydia testing, retesting, reinfection and PID rates, and to estimate MoCCA intervention costs. Our findings will guide scale-up plans for Australian general practice., Ethics and Dissemination: Ethics approval was obtained from The University of Melbourne Human Research Ethics Committee (Ethics ID: 22665). Findings will be disseminated via conference presentations, peer-reviewed publications and study reports., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Improving access to sexual health services is critical in light of rising sexually transmitted infections (STIs). We evaluated a hub-and-spoke model for improving access to sexual health services in three general practices in Victoria, Australia. The primary outcome was the impact on HIV and STI (chlamydia, gonorrhoea, syphilis) testing. Segmented linear regression analysis was conducted to examine the trends in the total HIV/STI tests pre- (from January 2019 to June 2020) and post-implementation (from July 2020 to July 2021). We evaluated the feasibility and acceptability of integrating this model into the general practices using semi-structured individual interviews. There was a statistically significant rise in testing for HIV and STIs in all general practices: post-implementation, there was an increase of an average of 11.2 chlamydia tests per month ( p = 0.026), 10.5 gonorrhoea tests per month ( p = 0.001), 4.3 syphilis tests per month ( p = 0.010), and 5.6 HIV tests per month ( p = 0.010). Participants reported increases in knowledge level and confidence in offering STI testing and managing a greater variety of sexual health cases. This study demonstrates the feasibility of implementing a hub-and-spoke model to enable GPs to deliver sexual health care with support from a sexual health specialist service.

Abstract: This analysis of notified syphilis cases in Victoria, Australia between 2015 and 2018 shows that the syphilis epidemic in Victoria has become more generalized, with increases among heterosexual men and women residing in outer Melbourne suburbs-areas that differ from those of gay men., Competing Interests: Conflict of Interest and Sources of Funding: E.P.F.C. is supported by an Australian National Health and Medical Research Council (NHMRC) Emerging Leadership Investigator Grant (GNT1172873).

Background: To examine completion of the human papillomavirus (HPV) vaccination 3-dose regimen and factors associated with completion among men who have sex with men (MSM) aged ≤ 26 years participating in a time-limited HPV catch-up vaccination program in Victoria, Australia. Methods: MSM who received their first dose of HPV vaccine at Melbourne Sexual Health Centre in 2017 were followed until October 2019. Vaccination completion was defined as those who received three doses. Multivariable logistic regression was performed to examine factors associated with vaccine completion. Results: 931 of 1,947 (47.8%) eligible men received at least one dose of HPV vaccine, 750 (38.5%) received two and 590 (30.3%) received three doses. The median time to receiving the second and third dose was 2.8 (IQR = 2.1-4.8) and 7.2 (IQR = 6.3-10.7) months, respectively. Gay men had higher odds of receiving three doses compared to bisexual men (aOR = 2.17; 95%CI: 1.16-4.04). Compared with HIV-negative MSM not taking PrEP, HIV-positive MSM were more like to complete vaccination (aOR = 3.92, 95%CI: 1.62-9.47) but no difference was found compared to HIV-negative men taking PrEP (aOR = 1.55; 95%CI: 0.95-2.53). Conclusion: Less than one-third of men aged ≤ 26 years completed the three doses of HPV vaccine. Further studies are needed to understand the barriers of men not completing the vaccine., Competing Interests: EC, MC, and CF have received research funding from Merck Sharp & Dohme, outside the submitted work.

Background: The Victorian legislation prohibits sex workers from working when they have visible anogenital herpes or warts. The aim of this study was to determine the proportion of asymptomatic female sex workers (FSW) diagnosed with anogenital herpes or warts by genital examination., Methods: We analysed all computerised medical records of consultations with FSW at the Melbourne Sexual Health Centre (MSHC) in 2018. All asymptomatic sex workers were offered screening sexually transmitted infections (STIs) and a genital examination to identify visible anogenital herpes or warts at MSHC. FSW consultations were categorised into either 'asymptomatic' or 'symptomatic' based on the presence of symptoms reported by the FSW to the triage nurse. The proportion of asymptomatic FSW diagnosed with visible anogenital herpes or warts during a routine screening examination was calculated., Results: In 2018, 4055 consultations were provided to 1979 FSW. 3406 of these consultations were asymptomatic and all were examined by an experienced clinician for signs of STIs. Of these 3406 asymptomatic consultations, seven FSW (0.21%, 95% CI: 0.08% to 0.42%) were diagnosed with visible anogenital herpes and/or warts following a genital examination. Four were diagnosed with warts (0.12%, 95% CI: 0.03% to 0.30%), two with herpes (0.06%, 95% CI: 0.01% to 0.21%) and one with both herpes and warts (0.03%, 95% CI: 0.001% to 0.16%)., Conclusion: Based on these data, approximately 500 asymptomatic FSW would need to be examined to identify one case of anogenital herpes or warts. Genital examinations consume considerable clinical resources, increase the duration of consultations and provide essentially no significant benefit to the mandated testing for gonorrhoea, chlamydia, HIV and syphilis. Our clinic will use self-collected samples and no longer examine FSW who are asymptomatic., Competing Interests: The authors have declared that no competing interests exist.

Objectives: In 2017, an outbreak of hepatitis A among gay, bisexual and other men who have sex with men (MSM) was reported in Victoria, Australia. In 2018, the Victorian government implemented a free hepatitis A vaccination programme targeting all Victorian MSM. This study aimed to determine hepatitis A vaccine uptake among MSM in a sexual health clinic in Melbourne., Methods: All MSM attending the Melbourne Sexual Health Centre (MSHC) in 2018 were included. Chart review was performed to determine the proportion of men vaccinated for at least one dose of hepatitis A and to examine why men did not receive the vaccine. Multivariable logistic regression was performed to examine the factors associated with vaccine uptake. Vaccine uptake was defined as receipt of at least one dose of hepatitis A vaccine., Results: Of the 9582 MSM who attended MSHC in 2018, 61.3% (95% CI 60.3% to 62.2%) self-reported already being immune to hepatitis A. Of the 3713 remaining eligible men, 62.7% (95% CI 61.1% to 64.2%) received at least one dose of the hepatitis A vaccine on the day of attendance. Compared with MSM not living with HIV and not taking pre-exposure prophylaxis (PrEP), MSM taking PrEP (adjusted OR 1.28; 95% CI 1.01 to 1.62) were more likely to receive the vaccine. 1386 men (37.3%) did not receive the vaccine and 55.4% were not offered the vaccine by their treating clinician. 300 men (21.6%) were identified as non-immune after serological testing but did not return for vaccination. By the end of 2018, 85.5% of MSHC attendees (8196/9582) were immune to hepatitis A., Conclusion: The critical vaccination threshold for hepatitis A has been estimated at >70%. Continuation of the targeted hepatitis A vaccination programme will improve immunity among the MSM population to prevent ongoing transmission and the likelihood of future outbreaks., Competing Interests: Competing interests: EPFC was supported by the National Health and Medical Research Council (NHMRC) Early Career Fellowships (1091226).

Whole genome sequencing (WGS) has been used to investigate transmission of Neisseria gonorrhoeae, but to date, most studies have not combined genomic data with detailed information on sexual behaviour to define the extent of transmission across population risk groups (bridging). Here, through combined epidemiological and genomic analysis of 2,186N. gonorrhoeae isolates from Australia, we show widespread transmission of N. gonorrhoeae within and between population groups. We describe distinct transmission clusters associated with men who have sex with men (MSM) and heterosexuals, and men who have sex with men and women (MSMW) are identified as a possible bridging population between these groups. Further, the study identifies transmission of N. gonorrhoeae between HIV-positive and HIV-negative individuals receiving pre-exposure prophylaxis (PrEP). Our data highlight several groups that can be targeted for interventions aimed at improving gonorrhoea control, including returning travellers, sex workers, and PrEP users.

Background Since 2014 there has been an increase in gonorrhoea among heterosexuals in Australia. Sex with a partner from a country with high gonorrhoea prevalence has been identified as a risk factor for gonorrhoea in heterosexual females, but risk factors for heterosexual males remain unclear. This study determined risk factors for gonorrhoea among heterosexual males., Methods: Retrospective analysis was performed among heterosexual males attending Melbourne Sexual Health Centre (MSHC) between 1 January 2007 and 31 December 2017. Countries for overseas sexual partners were stratified as high-prevalence countries (HPC) or low-prevalence countries (LPC) based on the incidence of gonorrhoea., Results: The annual gonorrhoea positivity increased from 0.72% in 2007 to 1.33% in 2017 (Ptrend <0.001). Males attending MSHC as a contact of gonorrhoea had the highest odds of testing positive (adjusted odds ratio (aOR) 7.46; 95% confidence interval (CI) 4.46-12.49), followed by males identifying as Aboriginal and Torres Strait Islander (aOR 2.57; 95% CI 1.30-5.09), males who had injected drugs in the past 12 months (aOR 2.44; 95% CI 1.39-4.30) and males who had sex with a female from an HPC (aOR 2.18; 95% CI 1.77-2.68). Males aged ≥35 were at higher risk than those aged ≤24 years (aOR 1.44; 95% CI 1.14-1.82). Gonorrhoea positivity increased among males who had sex with females from an LPC (from 0.60% to 1.33%; Ptrend = 0.004) but remained the same over time among males who had sex with females from an HPC (2.14%; Ptrend = 0.143)., Conclusions: There was an 80% increase in urethral gonorrhoea among heterosexual males between 2007 and 2017. Having sex with a female from an HPC is a significant risk factor for gonorrhoea. Gonorrhoea positivity among men having sex with a female from an HPC did not change over time, suggesting this risk factor has become less important.

Objective: In mid-2017, the Victorian Government funded a free time-limited human papillomavirus (HPV) vaccination catch-up programme for gay and bisexual men who have sex with men (MSM) aged up to 26 years through sexual health clinics or other immunisation centres. We aimed to examine the uptake of the HPV vaccine among young MSM attending the Melbourne Sexual Health Centre (MSHC)., Methods: MSM aged ≤26 attending MSHC between 27 April 2017 and 31 December 2017 were included in the analysis. HPV vaccine uptake was calculated based on the first consultation of each patient during the period. Multivariable logistic regression was performed to examine the association between vaccine uptake and patient factors., Results: There were 2108 MSM aged ≤26 who attended MSHC over the study period, with 7.6% (n=161) reporting previous HPV vaccination. Of the 1947 eligible men, 1134 (58.2%, 95% CI 56.0% to 60.4%) were offered the vaccine by the clinicians, and 830 men received it on the day. The vaccine coverage among all eligible MSM was 42.6% (95% CI 40.4% to 44.9%; 830 of 1947) and among MSM who were offered the vaccine by the clinicians was 73.2% (95% CI 70.5% to 75.8%; 830 of 1134). Men with a history of genital warts (adjusted OR (aOR)=3.11, 95%CI 1.39 to 6.99) and those who had >4male partners in the last 12 months (aOR=1.38, 95% CI 1.04 to 1.85) were more likely to receive the HPV vaccine on the day. 304 men declined the vaccine; most men did not specify the reason (31.3%, n=95), while 27.3% (n=83) needed time to think., Conclusion: Although vaccine uptake was 73.2% among those offered, the actual coverage of those eligible remained unsatisfactory (42.6%) in a sexual health clinic. This highlights a clinic-based targeted MSM programme may not reach sufficiently high vaccine coverage to provide MSM with the same vaccine benefits as heterosexuals., Competing Interests: Competing interests: EPFC has received educational grants from Seqirus Australia to assist with education, training and for academic purposes in the area of HPV.

Background On 26 July 2016, Victoria began a large study of HIV pre-exposure prophylaxis, called PrEPX, that involved the creation of around 2600 appointments over 3 months across multiple sites in Melbourne, Australia. At this time, the Melbourne Sexual Health Centre (MSHC) appeared to have a larger demand on its services. The aim of the present study was to determine whether this apparent increase in demand was substantially different from other demand fluctuations., Methods: Patients presenting to the MSHC from 2014 to 2016 were reviewed. Demographic characteristics, sexual risks and sexually transmitted infection diagnoses were extracted from the clinical database., Results: There were 115522 walk-in presentations for care and a rise in presentations in the week following the launch of the PrEPX study, but at least six similar peaks occurred that year. The peak coinciding with the launch of PrEPX was only apparent for men who have sex with men. There was a substantial increase in the proportion of patients who could not be seen (i.e. triaged out), from 10% in the week before PrEPX to 22.2% in the second week after, but this was primarily due to staff absences. At the time of the PrEPX study, data were collected on the duration of symptoms for common conditions and found no significant (P>0.29) change in the average duration of symptoms compared with that seen before the PrEPX launch., Conclusions: The increase in the number of medical consultations required for the PrEPX study did not result in excessive demand for public sexual health services.

Background: Receptive condomless anal sex is a known risk factor for anorectal chlamydia, but it remains unclear whether oroanal sex practices also contribute. We aimed to determine whether oroanal sex ("rimming"), fingering, or the use of saliva as anal lubricant are risk factors for anorectal chlamydia among men who have sex with men (MSM)., Methods: This cross-sectional study was conducted at Melbourne Sexual Health Centre from July 2014 to June 2015. Routinely collected computer-assisted self-interview data included demographics, number of sexual partners, and condom use. We added questions on receptive rimming, receptive fingering or penis "dipping," and the use of a partner's saliva as anal lubricant., Results: A total of 1691 MSM completed the questionnaire and tested for anorectal chlamydia. In univariable analyses, anorectal chlamydia was associated with using a partner's saliva as lubricant (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.26-3.09), receptive rimming (OR 1.59; 95% CI 1.04-2.45), and receptive fingering or dipping (OR 1.90; 95% CI 1.06-3.43). In multivariable analysis, anorectal chlamydia was not associated with these sexual practices, after adjusting for number of sexual partners, HIV status, known contact with chlamydia, and condom use. However, collinearity between sexual practices likely obscured associations with anorectal chlamydia, and further analyses suggested weak associations between these sexual practices and anorectal chlamydia., Conclusions: The use of a partner's saliva during receptive anal sex practices such as rimming, fingering, or penis dipping were weak risk factor for anorectal chlamydia in MSM. This contrasts with our previously reported findings that the use of saliva as anal lubricant is more strongly associated with anorectal gonorrhea.

Background: We report clinical characteristics of proctitis caused solely by Mycoplasma genitalium (MG) compared with chlamydia and gonococcus. We determined the proportions cured with first-line (azithromycin) and second-line antimicrobials (moxifloxacin, pristinamycin)., Methods: A total of 166 patients attending Melbourne Sexual Health Centre from 2012 to 2016 with symptoms of proctitis were tested for MG, Chlamydia trachomatis, and Neisseria gonorrhoeae. Demographic characteristics, sexual behaviors, clinical symptoms, and signs were recorded. Multinomial multivariable logistic regression was used to test for significant differences in symptoms and signs for the pathogens detected., Results: Seventeen percent of men had MG (95% confidence interval, 12-24), 21% had chlamydia (15-27), and 40% had gonococcal monoinfection (32-48), whereas 22% had MG coinfection (16-29). Relative to men with MG monoinfection, those with chlamydial monoinfection reported more anal pain (adjusted prevalence odds ratio (aPOR), 4.68 [1.41-14.19]), whereas men with gonococcal monoinfection reported more anal pain (aPOR, 6.75 [2.21-20.55]) and tenesmus (aPOR, 15.44 [1.62-146.90]), but less anal itch (aPOR, 0.32 [0.11-0.93]). The microbiological cure for MG using azithromycin was low at 35% (22-50), whereas moxifloxacin subsequently cured 92% (64-100) and pristinamycin cured 79% (54-94) of infections., Conclusions: M. genitalium was almost as common as chlamydia in men presenting to a sexual health center with symptoms of proctitis. Men with anorectal MG monoinfection were less likely to have symptoms and signs compared with those with chlamydia or gonococcus monoinfection. Cure for men with symptomatic anorectal MG by azithromycin was low. We suggest routine testing for MG in cases of proctitis, with test of cure after treatment being essential.

Background: This before-and-after study measured the impact of a change in testing methods from culture to nucleic acid amplification testing (NAAT) on the detection of pharyngeal and rectal gonorrhea in men who have sex with men (MSM) on a sexual health service level, including the effect on subgroups anticipated to have higher rates of gonorrhea., Methods: In March 2015, Melbourne Sexual Health Centre changed its laboratory method for gonococcal testing from culture to NAAT using the Aptima Combo 2 and Aptima GC tests. We compared the proportion of tests positive for rectal and pharyngeal gonorrhea in MSM using culture in 2014 with those using NAAT in 2015., Results: The proportion of tests positive for rectal gonorrhea by NAAT was double that obtained by culture (8% vs 3.9%; prevalence ratio [PR], 2.0; 95% confidence interval [CI], 1.8-2.4) and 5-fold for pharyngeal gonorrhea (8.3% vs 1.6%; PR, 5.2; 95% CI, 4.2-6.4). Similar increases in test positivity were observed in human immunodeficiency virus (HIV)-positive and HIV-negative men. By NAAT, test positivity for rectal gonorrhea was higher in HIV-positive compared with HIV-negative men (15.4% vs 7.3%; PR, 2.1; 95% CI, 1.7-2.6). Culture and NAAT had similar test positivity for rectal gonorrhea among men who reported contact with gonorrhea (24.9% vs 25.3%, PR 1.0, 95% CI 0.8-1.4) and men who presented with symptoms of proctitis (22.2% vs 27.9%, PR 1.3, 95% CI 0.8-2.0)., Conclusions: A switch from culture to Aptima Combo 2 testing for extragenital gonorrhea in MSM increased detection and was most marked for pharyngeal infections.

Background: Understanding retention and loss to follow up in HIV care, in particular the number of people with unknown outcomes, is critical to maximise the benefits of antiretroviral therapy. Individual-level data are not available for these outcomes in Australia, which has an HIV epidemic predominantly focused amongst men who have sex with men., Methods and Findings: A network of the 6 main HIV clinical care sites was established in the state of Victoria, Australia. Individuals who had accessed care at these sites between February 2011 and June 2013 as assessed by HIV viral load testing but not accessed care between June 2013 and February 2014 were considered individuals with potentially unknown outcomes. For this group an intervention combining cross-referencing of clinical data between sites and phone tracing individuals with unknown outcomes was performed. 4966 people were in care in the network and before the intervention estimates of retention ranged from 85.9%-95.8% and the proportion with unknown outcomes ranged from 1.3-5.5%. After the intervention retention increased to 91.4-98.8% and unknown outcomes decreased to 0.1-2.4% (p<.01 for all sites for both outcomes). Most common reasons for disengagement from care were being too busy to attend or feeling well. For those with unknown outcomes prior to the intervention documented active psychiatric illness at last visit was associated with not re-entering care (p = 0.04)., Conclusions: The network demonstrated low numbers of people with unknown outcomes and high levels of retention in care. Increased levels of retention in care and reductions in unknown outcomes identified after the intervention largely reflected confirmation of clinic transfers while a smaller number were successfully re-engaged in care. Factors associated with disengagement from care were identified. Systems to monitor patient retention, care transfer and minimize disengagement will maximise individual and population-level outcomes for populations with HIV.

Objectives: To examine whether the rapid increase of gonorrhoea notifications in Victoria, Australia, identified by nucleic acid amplification test (NAAT) is supported by similar changes in diagnoses by culture, which has higher specificity, and to determine the proportion of tests positive among women tested., Design, Setting and Participants: Retrospective analysis of Medicare reporting of dual NAATs in Victoria, Victorian Department of Health gonorrhoea notifications, and gonorrhoea culture data at the Melbourne Sexual Health Centre (MSHC), among women, 2008 to 2013., Main Outcome Measures: Gonorrhoea notifications and testing methods., Results: Gonorrhoea cases identified by NAAT increased from 98 to 343 cases over the study period. Notifications by culture alone decreased from 19 to five cases. The proportion of NAATs positive for gonorrhoea in Victoria was low (0.2%-0.3%) and did not change over time (P for trend, 0.66). Similarly, the proportion of women tested at the MSHC for gonorrhoea who tested positive (0.4%-0.6%) did not change over time (P for trend, 0.70). Of untreated women who had a positive NAAT result for gonorrhoea and were referred to the MSHC, 10/25 were confirmed by culture., Conclusions: The positivity of gonorrhoea in women identified by culture remains stable over time. Using NAAT for gonorrhoea screening in low-prevalence populations will result in many false positives. Positive NAAT results among low-risk women should be regarded as doubtful, and confirmatory cultures should be performed.

Background: The frequency of testing sex workers for sexually transmitted infections (STIs) in Victoria, Australia, was changed from monthly to quarterly on 6 October 2012. Our aim was to determine the impact of this change to the clients seen at the Melbourne Sexual Health Centre (MHSC)., Methods: Computerised medical records of all clients attending at MHSC from 7 October 2011 to 7 October 2013 were analysed., Results: Comparing between the monthly and quarterly testing periods, the number of consultations at MSHC with female sex workers (FSW) halved from 6146 to 3453 (p<0.001) and the consultation time spent on FSW reduced by 40.6% (1942 h to 1153 h). More heterosexual men (p<0.001), and women (p<0.001) were seen in the quarterly testing period. The number of STIs diagnosed in the clinic increased from 2243 to 2589 from the monthly to quarterly period, respectively [15.4% increase (p<0.001)]. Up to AU$247,000 was saved on FSW testing after the shift to quarterly testing., Conclusions: The change to STIs screening frequency for sex workers from monthly to quarterly resulted in a 15% increase in STI diagnoses in the clinic and approximate a quarter of a million dollars was diverted from FSW testing to other clients. Overall the change in frequency is likely to have had a beneficial effect on STI control in Victoria.

This study explored the health-care experiences of women diagnosed with pelvic inflammatory disease. Semi-structured interviews were conducted with 23 women diagnosed with pelvic inflammatory disease. Many women felt empowered about their health post-diagnosis; however, a smaller number reported becoming hyper-vigilant towards symptoms. Infertility was the greatest concern for women. Inadequate information and treatment resulted in negative health experiences, whereas clinician honesty and concern were viewed positively. The findings highlight the need for community education encouraging early presentation for the treatment of pelvic pain and emphasise the need for health practitioners to be responsive to the psychosocial aspects of pelvic inflammatory disease.

Background: We investigated the detection of chlamydia at different stages of the menstrual cycle., Methods: Electronic medical records for women attending Melbourne Sexual Health Centre between March 2011 and 31(st) December 2012, who were tested for chlamydia by nucleic acid amplification of high vaginal, cervical, or urinary samples, and who recorded a date of last normal menstrual period (LNMP) between 0-28 days were included in the analysis. Logistic regression was used to calculate adjusted odds ratio (aOR) and 95% confidence intervals (CI) for the association of chlamydia with menstrual cycle adjusted by demographics and behavioural variables. Chlamydia and beta globin load were determined on those with stored samples., Results: Of the 10,017 consultations that included a test for chlamydia and a valid LNMP, there were 417 in which chlamydia was detected. The proportion of samples with chlamydia was greater in the luteal phase (4.8%, 184/3831) than in the follicular phase (3.4%, 233/6816) both in the crude (OR 1.29 95%CI 1.1-1.6, p = 0.01) and adjusted odds ratio (aOR) 1.4 (95%CI 1.1-1.8, p = 0.004). Among women using hormonal contraception, there was no significant association with the luteal phase of the menstrual cycle (aOR 1.3, 95%CI 0.9, 1.8, p = 0.18). Among women not using hormonal contraception, there was a significant association with the luteal phase (aOR 1.6, (95% CI 1.1-2.3, p = 0.007). The chlamydia load was not significantly different in the 329 positive stored samples in weeks 3 and 4 vs weeks 1 and 2 for any site (P>0.12)., Conclusions: The higher detection of chlamydia detection in the luteal phase of the menstrual cycle in only those not taking hormonal contraception suggest that hormonal factors influence chlamydia detection. The absence of a significantly highly chlamydia load in women during the luteal phase raises questions about the mechanism.

Objectives: To assess the proportion of female sex workers (FSWs) from low-prevalence ('other') and high-prevalence countries (HPCs) for sexually transmissible infections (STIs) in Melbourne., Methods: Retrospective data analysis from the Melbourne Sexual Health Centre database for February 2002-May 2011., Results: Some 1702 HPC FSWs, 2594 other FSWs and 13?644 nonFSW women were included, with 12?891 and 21?611 consultations, respectively, for HPC FSWs and other FSWs. Proportions of HPC FSWs with chlamydia (Chlamydia trachomatis) (4.2% v. 3.3%, P=0.14), gonorrhoea (Neisseria gonorrhoeae) (0.24% v. 0.31%, P=0.66) or trichomonas (0.65 v. 0.46, P=0.42) at first visit were similar to those of other FSWs, but nonFSWs had a higher prevalence of chlamydia and gonorrhoea (P<0.01). On return visits, chlamydia (1.2% v. 0.92%, P<0.05) and gonorrhoea (0.29% v. 0.10%, P=<0.05) were more common in HPC FSWs than other FSWs. The presence of any of these STIs among FSWs was predicted by having private nonpaying partners in the last year (adjusted odds ratio (AOR): 1.99 (95% confidence interval (CI): 1.52-2.61)), having private partners from overseas (AOR: 1.69 (95% CI: 1.33-2.16)) and being a HPC FSW (AOR: 1.38 (95% CI: 1.12-1.72)). Injecting drug use was less common in HPC FSWs than in other FSWs (0.82% v. 16.54%, P<0.0001)., Conclusions: STI prevalence was low among FSWs from countries with high and low background STI. Among FSWs having private sex partners and private partners from overseas were the primary predictors for STIs.

Background: Epidemics of hepatitis A among men who have sex with men (MSM) have decreased significantly in recent years although the level of immunity that is required to prevent epidemics has not been studied. Our aim was to determine the level of immunity to hepatitis A among MSM., Methods: This was a retrospective study conducted using notifications of Hepatitis A in Victoria from 1991 to 2010, serological testing for hepatitis A among MSM attending Melbourne Sexual Health Centre (MSHC), and vaccination records among MSM attending MSHC., Results: Hepatitis A notifications declined from 370 to 47 and the male to female ratio declined from 4.2 to 0.9 in Victoria between 1991 to 2010. Between 2002 and 2011, there were 12,064 individuals MSM seen at MSHC of whom 3055 (25%) were tested for hepatitis A antibodies and 1180 (39%) had antibodies. The proportion of MSM who were tested for hepatitis A rose significantly over time (P<0.01), but the proportion of these with hepatitis A antibodies did not (P=0.28). Hepatitis A antibodies were more common in MSM over 30 (54%) compared to those 30 or less (32%), (Crude Odds Ratio 2.5 (95% confidence interval 2.1-2.9)) and were uncommon in MSM under 20 (19%). Vaccination against hepatitis A was recorded in 49% of 660 clinical files of MSM who attended the centre between 2003 and 2011 and did not change over time (P=0.42) but was significantly more common in those over 30 years of age (P<0.005)., Conclusion: Hepatitis A is rare in MSM in Victoria where levels of immunity are about 40-50%. As outbreaks have occurred when levels of immunity were around 30%, maintaining vaccination levels over 40-50% is important if outbreaks are to be prevented. The lower levels of immunity in younger MSM create the potential for outbreaks in this sub-group., (Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.)

The present study aimed to determine whether pelvic examinations change clinical management of women with asymptomatic chlamydia infection. Records for women with asymptomatic chlamydia who underwent a pelvic examination at a sexual health clinic in Melbourne, Australia (January 2006 to June 2007) were analysed retrospectively. Of 91 cases, 31 (34%) warranted examination; one woman (1%; 95% confidence interval: 0.5%, 6.4%) had muco-purulent cervicitis and mild tenderness, and was treated for possible pelvic inflammatory disease. These data suggest that a pelvic examination will lead to changes in treatment for very few women diagnosed with asymptomatic chlamydia infection.

Background: Financial incentives have been used for many years internationally to improve quality of care in general practice. The aim of this pilot study was to determine if offering general practitioners (GP) a small incentive payment per test would increase chlamydia testing in women aged 16 to 24 years, attending general practice., Methods: General practice clinics (n = 12) across Victoria, Australia, were cluster randomized to receive either a $AUD5 payment per chlamydia test or no payment for testing 16 to 24 year old women for chlamydia. Data were collected on the number of chlamydia tests and patient consultations undertaken by each GP over two time periods: 12 month pre-trial and 6 month trial period. The impact of the intervention was assessed using a mixed effects logistic regression model, accommodating for clustering at GP level., Results: Testing increased from 6.2% (95% CI: 4.2, 8.4) to 8.8% (95% CI: 4.8, 13.0) (p = 0.1) in the control group and from 11.5% (95% CI: 4.6, 18.5) to 13.4% (95% CI: 9.5, 17.5) (p = 0.4) in the intervention group. Overall, the intervention did not result in a significant increase in chlamydia testing in general practice. The odds ratio for an increase in testing in the intervention group compared to the control group was 0.9 (95% CI: 0.6, 1.2). Major barriers to increased chlamydia testing reported by GPs included a lack of time, difficulty in remembering to offer testing and a lack of patient awareness around testing., Conclusions: A small financial incentive alone did not increase chlamydia testing among young women attending general practice. It is possible small incentive payments in conjunction with reminder and feedback systems may be effective, as may higher financial incentive payments. Further research is required to determine if financial incentives can increase testing in Australian general practice, the type and level of financial scheme required and whether incentives needs to be part of a multi-faceted package., Trial Registration: Australian New Zealand Clinical Trial Registry ACTRN12608000499381.

Background: Chlamydia trachomatis is the most common notifiable disease in Australia, mainly affecting those aged 15 to 29 years. Testing rates are low in Australia and considerably lower in rural areas, with access and confidentiality of sexual health services being problematic in rural and regional areas. This study aimed to determine the feasibility of establishing a pilot chlamydia testing outreach program among 16-25 year old males and females in rural Victoria (Australia) undertaken at local sporting clubs and to determine the prevalence of chlamydia and acceptability of the program in this population., Methods: We aimed to recruit young people from the Loddon Mallee region of Victoria, Australia between May and September 2007. After a night of sporting practice, participants provided a first pass urine sample, completed a brief questionnaire regarding risk taking behaviour and were then provided with condoms and health promotion materials about sexually transmitted infections (STIs). Those positive for chlamydia were managed by telephone consultation with a practitioner from Melbourne Sexual Health Centre., Results: A total of 709 young people participated (77% male, 23% female), 77% being sexually active. All provided a urine sample and completed the questionnaire. Participation rate on recruitment nights was over 95%. Overall chlamydia prevalence in those sexually active was 5.1% (95%CI: 3.4-7.3), 7.4% in females (95%CI: 3.5-13.6) and 4.5% in males (95%CI: 2.7-6.9)., Conclusion: Sporting clubs represent a feasible, acceptable and innovative community based setting to screen, treat and educate young people in a rural and regional setting, especially for males.

The objective of this study was to determine the effectiveness of a statewide campaign aimed at increasing chlamydia awareness and testing among younger people. In November 2002, a narrowcast media campaign targeting men and women aged 16-29 years was launched in Victoria, Australia. This was expanded in June 2003. Data on chlamydia testing via Medicare and chlamydia notifications, before and after the campaign, were compared to determine possible effects of the campaign on population rates of chlamydia testing and detection. During the campaign, chlamydia testing rates increased significantly for both women (P=0.04) and men (P=0.04), while testing rates before and after the campaign remained relatively stable. Although testing rates increased, only 4.3% of Victorian women and 1.9% of men aged 16-30 were tested through Medicare in 2003. The increase in chlamydia testing over the study period was closely paralleled by an increase in notification rates for chlamydia, with strong correlations between the two (r=0.97, P<0.001). In conclusion, an estimated minimum of A$70 was spent on the campaign for each additional chlamydia test performed. Testing within the framework of a national chlamydia screening programme may be a more cost-effective way of increasing chlamydia testing.
