Client and staff perceptions of acceptability of MyCheck: a direct-to-pathology telehealth and e-testing service for comprehensive bloodborne virus and sexually transmissible infection screening.

Background Sydney Sexual Health Centre (SSHC) is the largest sexual health clinic in New South Wales (NSW), servicing clients at high risk of sexually transmissible infections and bloodborne viruses. SSHC piloted a direct-to-pathology pathway that facilitated bloodborne virus/sexually transmissible infection testing at one of the ~500 participating pathology collection centres located across NSW. This qualitative study sought to understand SSHC client and provider perspectives of acceptability of the MyCheck intervention. Methods Semi-structured in-depth interviews were conducted with 11 clients who underwent testing via the MyCheck pathway and eight staff members involved in implementing MyCheck. The seven components of Sekhon's Theoretical Framework of Acceptability informed this analysis. Results Participants broadly conveyed 'affective attitude' toward the MyCheck pathway. The telehealth intervention reduced client 'burden' and 'opportunity cost' through enabling greater testing convenience at a location suitable to them and provided timely results. Issues of 'ethicality' were raised by clients and staff as pathology centre staff were, on a few occasions, regarded as being judgmental of SSHC clients. 'Intervention coherence' issues were largely attributed to pathology centre personnel being unfamiliar with the intervention, with billing issues being a recurrent concern. Participants perceived MyCheck as an 'effective' testing pathway. SSHC staff were able to offer the intervention with ease through seamless IT integration ('self-efficacy'). Conclusion The MyCheck intervention was perceived by both SSHC clients and staff as an acceptable bloodborne virus/sexually transmissible infection testing pathway. However, further work is required to address stigma experienced by some clients when attending pathology collection centres.

Characteristics of Human Immunodeficiency Virus (HIV) Seroconversions in a Large Prospective Implementation Cohort Study of Oral HIV Preexposure Prophylaxis in Men Who Have Sex with Men (EPIC-NSW).

BACKGROUND: Most human immunodeficiency virus (HIV) seroconversions in people who have initiated preexposure prophylaxis (PrEP) occur in the context of insufficient adherence. We describe participants who seroconverted after being dispensed PrEP in a large PrEP implementation study in Australia. METHODS: Expanded PrEP Implementation in Communities in New South Wales was an implementation study of daily oral PrEP in individuals aged ≥18 years at high risk for acquiring HIV. HIV seroconversions were defined as a positive HIV test by either antigen, antibody, or detectable HIV viral load after enrollment. Insufficient adherence, measured by dispensing logs or participant self-report, was defined as <4 PrEP doses per week. RESULTS: A total of 9596 participants were enrolled and dispensed PrEP between 1 March 2016 and 30 April 2018; 30 were diagnosed with HIV by 31 March 2019. The median (interquartile range [IQR]) age was 31 (25-38) years, all identified as male, 29 (97%) identified as gay or homosexual, and 20 (69%) lived in a postcode with a low concentration of gay male residents. The median (IQR) days from first PrEP dispensing to diagnosis was 409 (347-656). There was no evidence that participants who seroconverted had been sufficiently adherent to PrEP. Nineteen (63%) participants who seroconverted were diagnosed with chlamydia, gonorrhoea, syphilis, or new hepatitis C infection. One participant had resistance to emtricitabine (M184V mutation) at diagnosis. CONCLUSIONS: Participants who seroconverted were insufficiently adherent to PrEP despite being at high risk for acquiring HIV. Understanding the reasons for poor PrEP adherence in individuals who subsequently acquire HIV is critical to improving PrEP effectiveness.

Infectious syphilis in women and heterosexual men in major Australian cities: sentinel surveillance data, 2011-2019.

OBJECTIVES: To examine changes in the positive infectious syphilis test rate among women and heterosexual men in major Australian cities, and rate differences by social, biomedical, and behavioural determinants of health. DESIGN, SETTING: Analysis of data extracted from de-identified patient records from 34 sexual health clinics participating in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance of Sexually Transmissible Infections and Blood Borne Viruses (ACCESS). PARTICIPANTS: First tests during calendar year for women and heterosexual men aged 15 years or more in major cities who attended ACCESS sexual health clinics during 2011-2019. MAIN OUTCOME MEASURES: Positive infectious syphilis test rate; change in annual positive test rate. RESULTS: 180 of 52 221 tested women (0.34%) and 239 of 36 341 heterosexual men (0.66%) were diagnosed with infectious syphilis. The positive test rate for women was 1.8 (95% confidence interval [CI], 0.9-3.2) per 1000 tests in 2011, 3.0 (95% CI, 2.0-4.2) per 1000 tests in 2019 (change per year: rate ratio [RR], 1.12; 95% CI, 1.01-1.25); for heterosexual men it was 6.1 (95% CI, 3.8-9.2) per 1000 tests in 2011 and 7.6 (95% CI, 5.6-10) per 1000 tests in 2019 (RR, 1.10; 95% CI, 1.03-1.17). In multivariable analyses, the positive test rate was higher for women (adjusted RR [aRR], 1.85; 95% CI, 1.34-2.55) and heterosexual men (aRR, 2.39; 95% CI, 1.53-3.74) in areas of greatest socio-economic disadvantage than for those in areas of least socio-economic disadvantage. It was also higher for Indigenous women (aRR, 2.39; 95% CI, 1.22-4.70) and for women who reported recent injection drug use (aRR, 4.87; 95% CI, 2.18-10.9) than for other women; it was lower for bisexual than heterosexual women (aRR, 0.48; 95% CI, 0.29-0.81) and for women who reported recent sex work (aRR, 0.35; 95% CI, 0.29-0.44). The positive test rate was higher for heterosexual men aged 40-49 years (aRR, 2.11; 95% CI, 1.42-3.12) or more than 50 years (aRR, 2.36; 95% CI, 1.53-3.65) than for those aged 15-29 years. CONCLUSION: The positive test rate among both urban women and heterosexual men tested was higher in 2019 than in 2011. People who attend reproductive health or alcohol and drug services should be routinely screened for syphilis.

Australian sexually transmitted infection (STI) management guidelines for use in primary care 2022 update.

The 'Australian Sexually Transmitted Infection (STI) Management Guidelines For Use In Primary Care' (www.sti.guidelines.org.au ) provide evidence-based, up-to-date guidance targeted at use in primary care settings. A major review of the guidelines was undertaken in 2020-22. All content was reviewed and updated by a multi-disciplinary group of clinical and non-clinical experts, and assessed for appropriateness of recommendations for key affected populations and organisational and jurisdictional suitability. The guidelines are divided into six main sections: (1) standard asymptomatic check-up; (2) sexual history; (3) contact tracing; (4) STIs and infections associated with sex; (5) STI syndromes; and (6) populations and situations. This paper highlights important aspects of the guidelines and provides the rationale for significant changes made during this major review process.

Interim position statement on doxycycline post-exposure prophylaxis (Doxy-PEP) for the prevention of bacterial sexually transmissible infections in Australia and Aotearoa New Zealand - the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine (ASHM).

Recent studies have provided evidence for the effectiveness of using doxycycline (Doxy-PEP) to prevent bacterial sexually transmissible infections (STI), namely chlamydia, gonorrhoea, and syphilis, among gay, bisexual, and other men who have sex with men who have experienced multiple STIs. However, there remain several unanswered questions around potential adverse outcomes from Doxy-PEP, including the possibility of inducing antimicrobial resistance in STIs and other organisms, and the possibility of disrupting the microbiome of people who choose to use Doxy-PEP. This interim position statement from the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine aims to outline the current evidence for Doxy-PEP, and to highlight potential adverse outcomes, to enable clinicians to conduct evidence-based conversations with patients in Australia and Aotearoa New Zealand who intend to use Doxy-PEP.

Young Aboriginal people's engagement with STI testing in the Northern Territory, Australia.

BACKGROUND: Australian surveillance data document higher rates of sexually transmissible infections (STIs) among young Aboriginal people (15-29 years) in remote settings than non-Aboriginal young people. Epidemiological data indicate a substantial number of young Aboriginal people do not test for STIs. Rigorous qualitative research can enhance understanding of these findings. This paper documents socio-ecological factors influencing young Aboriginal people's engagement with clinic-based STI testing in two remote settings in the Northern Territory, Australia. METHODS: In-depth interviews with 35 young Aboriginal men and women aged 16-21 years; thematic analysis examining their perceptions and personal experiences of access to clinic-based STI testing. RESULTS: Findings reveal individual, social and health service level influences on willingness to undertake clinic-based STI testing. Individual level barriers included limited knowledge about asymptomatic STIs, attitudinal barriers against testing for symptomatic STIs, and lack of skills to communicate about STIs with health service staff. Social influences both promoted and inhibited STI testing. In setting 1, local social networks enabled intergenerational learning about sexual health and facilitated accompanied visits to health clinics for young women. In setting 2, however, social connectedness inhibited access to STI testing services. Being seen at clinics was perceived to lead to stigmatisation among peers and fear of reputational damage due to STI-related rumours. Modalities of health service provision both enhanced and inhibited STI testing. In setting 1, outreach strategies by male health workers provided young Aboriginal men with opportunities to learn about sexual health, initiate trusting relationships with clinic staff, and gain access to clinics. In setting 2, barriers were created by the location and visibility of the clinic, appointment procedures, waiting rooms and waiting times. Where inhibitive factors at the individual, social and health service levels exist, young Aboriginal people reported more limited access to STI testing. CONCLUSIONS: This is the first socio-ecological analysis of factors influencing young Aboriginal people's willingness to undertake testing for STIs within clinics in Australia. Strategies to improve uptake of STI testing must tackle the overlapping social and health service factors that discourage young people from seeking sexual health support. Much can be learned from young people's lived sexual health experiences and family- and community-based health promotion practices.

Outreach services to brothels facilitate sexually transmissible infection testing for Asian sex workers in regional Australia.

Outreach services providing sexually transmissible infection (STI) testing on-site in brothels were introduced in 2012 by Pacific Clinic Newcastle, Australia. Asian female sex workers (FSW) were more likely than non-culturally and linguistically diverse (CALD) FSW to access testing via outreach services than in clinics (OR 2.38, 95% CI 1.82-3.11, P < 0.0001) and to test positive for chlamydia or gonorrhoea (OR 2.58, 95% CI 1.58-4.20, P = 0.0001). Outreach services offering testing on-site in brothels are recommended to facilitate access for Asian FSW in similar settings.

Young Aboriginal people's sexual health risk reduction strategies: a qualitative study in remote Australia.

Background Surveillance data indicate that Aboriginal and Torres Strait Islander young people are more likely than their non-Indigenous counterparts to experience sexually transmissible infections (STIs) and teenage pregnancy. Despite increasing emphasis on the need for strengths-based approaches to Aboriginal sexual health, limited published data document how young Aboriginal people reduce sexual health risks encountered in their everyday lives. METHODS: In-depth interviews with 35 young Aboriginal women and men aged 16-21 years in two remote Australian settings were conducted; inductive thematic analysis examining sexual health risk reduction practices was also conducted. RESULTS: Participants reported individual and collective STI and pregnancy risk reduction strategies. Individual practices included accessing and carrying condoms; having a regular casual sexual partner; being in a long-term trusting relationship; using long-acting reversible contraception; having fewer sexual partners; abstaining from sex; accessing STI testing. More collective strategies included: refusing sex without a condom; accompanied health clinic visits with a trusted individual; encouraging friends to use condoms and go for STI testing; providing friends with condoms. CONCLUSION: Findings broaden understanding of young Aboriginal people's sexual health risk reduction strategies in remote Aboriginal communities. Findings signal the need for multisectoral STI prevention and sexual health programs driven by young people's existing harm minimisation strategies and cultural models of collective support. Specific strategies to enhance young people's sexual health include: peer condom distribution; accompanied health service visits; peer-led health promotion; continued community-based condom distribution; enhanced access to a fuller range of available contraception in primary care settings; engaging health service-experienced young people as 'youth health workers'.

Predictors of Daily Adherence to HIV Pre-exposure Prophylaxis in Gay/Bisexual Men in the PRELUDE Demonstration Project.

Adequate adherence to pre-exposure prophylaxis (PrEP) is critical to prevent HIV infection, but accurately measuring adherence remains challenging. We compared two biological [blood drug concentrations in plasma and peripheral blood mononuclear cells (PBMC)] and two self-reported measures (facilitated recall to clinicians and self-report in online surveys) and identified predictors of daily PrEP adherence among gay and bisexual men (GBM) in their first 12 months on PRELUDE, an open-label, single-arm PrEP demonstration project in New South Wales, Australia. 327 participants were enrolled; 263 GBM attended their 12-month follow-up visit (81% retention). Overall, 91% of blood samples had plasma drug concentrations indicative of taking 7 pills/week, and 99% had protective drug concentrations (≥ 4 pills/week). Facilitated recall to clinicians identified 99% of participants with protective adherence as measured by PBMC drug concentrations. Daily adherence measured by facilitated recall was associated with behavioural practices including group sex (aOR 1.33, 95% CI 1.15-1.53, p < 0.001). Retained participants maintained high adherence to daily PrEP over 12 months, confirmed by four different measures. Facilitated recall to clinicians is a suitable measure for assessing PrEP adherence in populations engaged in care where there is established trust and rapport with patients. Trial registration: ClinicalTrials.gov NCT02206555.

High Adherence to HIV Pre-exposure Prophylaxis and No HIV Seroconversions Despite High Levels of Risk Behaviour and STIs: The Australian Demonstration Study PrELUDE.

PrELUDE study evaluated daily pre-exposure prophylaxis (PrEP) in high-risk individuals in Australia. This open-label, single-arm study tested participants for HIV/STI and collected behavioural information three-monthly. We report trends over 18 months in medication adherence, side-effects, HIV/STI incidence and behaviour. 320 gay/bisexual men (GBM), 4 women and 3 transgender participants, followed on average 461 days, reported taking seven pills/week on 1,591 (88.5%) occasions and 4-6 pills/week on 153 (8.5%) occasions. No HIV infections were observed. STI incidence was high and stable, while gonorrhoea infections declined from 100.0 to 25.8/100 person-years between 6 and 15 months (p < 0.001). The number of HIV-positive and unknown-status sex partners, and condomless anal intercourse, significantly increased. In this high-risk cohort of mainly GBM, increases in risk behaviours and high STI incidence were not accompanied by HIV infections due to high adherence to daily PrEP. The study informed policy and further PrEP implementation among Australian GBM.

Molecular Antimicrobial Resistance Surveillance for Neisseria gonorrhoeae, Northern Territory, Australia.

Neisseria gonorrhoeae antimicrobial resistance (AMR) is a globally recognized health threat; new strategies are needed to enhance AMR surveillance. The Northern Territory of Australia is unique in that 2 different first-line therapies, based primarily on geographic location, are used for gonorrhea treatment. We tested 1,629 N. gonorrhoeae nucleic acid amplification test-positive clinical samples, collected from regions where ceftriaxone plus azithromycin or amoxicillin plus azithromycin are recommended first-line treatments, by using 8 N. gonorrhoeae AMR PCR assays. We compared results with those from routine culture-based surveillance data. PCR data confirmed an absence of ceftriaxone resistance and a low level of azithromycin resistance (0.2%), and that penicillin resistance was <5% in amoxicillin plus azithromycin regions. Rates of ciprofloxacin resistance and penicillinase-producing N. gonorrhoeae were lower when molecular methods were used. Molecular methods to detect N. gonorrhoeae AMR can increase the evidence base for treatment guidelines, particularly in settings where culture-based surveillance is limited.

The Molecular Epidemiology and Antimicrobial Resistance of Neisseria gonorrhoeae in Australia: A Nationwide Cross-Sectional Study, 2012.

BACKGROUND: Antimicrobial resistance (AMR) by Neisseria gonorrhoeae is considered a serious global threat. METHODS: In this nationwide study, we used MassARRAY iPLEX genotyping technology to examine the epidemiology of N. gonorrhoeae and associated AMR in the Australian population. All available N. gonorrhoeae isolates (n = 2452) received from Australian reference laboratories from January to June 2012 were included in the study. Genotypic data were combined with phenotypic AMR information to define strain types. RESULTS: A total of 270 distinct strain types were observed. The 40 most common strain types accounted for over 80% of isolates, and the 10 most common strain types accounted for almost half of all isolates. The high male to female ratios (>94% male) suggested that at least 22 of the top 40 strain types were primarily circulating within networks of men who have sex with men (MSM). Particular strain types were also concentrated among females: two strain types accounted for 37.5% of all isolates from females. Isolates harbouring the mosaic penicillin binding protein 2 (PBP2)-considered a key mechanism for cephalosporin resistance-comprised 8.9% of all N. gonorrhoeae isolates and were primarily observed in males (95%). CONCLUSIONS: This large scale epidemiological investigation demonstrated that N. gonorrhoeae infections are dominated by relatively few strain types. The commonest strain types were concentrated in MSM in urban areas and Indigenous heterosexuals in remote areas, and we were able to confirm a resurgent epidemic in heterosexual networks in urban areas. The prevalence of mosaic PBP2 harboring N. gonorrhoeae strains highlight the ability for new N. gonorrhoeae strains to spread and become established across populations.

Why are men less tested for sexually transmitted infections in remote Australian Indigenous communities? A mixed-methods study.

Gender disparities in testing rates for sexually transmitted infections (STIs) have been identified as one potential factor sustaining high rates of STIs and repeat infections in the Northern Territory of Australia, especially in remote Indigenous communities. The study aimed to investigate the reasons for these disparities utilising a mixed-method study design. We conducted an audit on client information at a remote community health clinic, focus-group discussions with young men in the same community and interviews with experienced remote area clinicians. The clinic audit found a significantly higher proportion of female residents of the community than males visited the clinic (72.8 versus 55.3%, p < 0.005). Women were also more likely to be tested for STIs than men when visiting the clinic (49.7 versus 40.3%, p = 0.015). Major barriers to men's seeking STI testing included a sense of shame from being seen visiting the clinic by women, men's lack of understanding of STIs and the need for testing, and inadequate access to male clinicians. Increasing men's access to healthcare and STI testing requires offering testing at a gender-sensitive and separate locations, and community-based sexual health promotion to increase knowledge of STIs.

Was infectious syphilis being misclassified in remote Australian outbreaks? Evidence that informed modification of the national case definition.

OBJECTIVE: To assess the ability of the national case definition to identify infectious syphilis during an outbreak affecting predominantly Aboriginal and Torres Strait Islander people in a remote Australian region. METHODS: A retrospective case series study of all non-congenital syphilis cases in the region notified between 1 January 2009 and 31 December 2012 was performed. The national infectious syphilis case definition was compared with an expanded case definition derived from experienced clinician assessment and the definition proposed in the Interim Guidelines for the Public Health Management of Syphilis Outbreaks in Remote Populations in Australia from the Communicable Diseases Network Australia (CDNA). RESULTS: Two hundred and forty syphilis cases were notified, of which 44 (18.3%) were symptomatic. The national case definition classified 106 (44.2%) cases as infectious, compared with 182 (75.8%) using the clinician-derived expanded case definition and 165 (68.8%) by the interim guidelines case definition. Seven confirmed and 6 probable cases were diagnosed as a result of contact tracing of probable infectious cases identified using the expanded case definition. CONCLUSIONS AND IMPLICATIONS: The national case definition for infectious syphilis applied in this remote Australian outbreak underestimated infectious cases when compared with experienced clinicians' evaluation by up to 76 cases (42%) and was inadequate to monitor the magnitude of a syphilis outbreak in such a setting. This may compromise surveillance and resource allocation decisions, and could reduce the capacity to interrupt transmission and contain an outbreak. A revised national case definition, informed by this analysis, was released by CDNA in July 2015.

Notification and management of congenital syphilis in the Northern Territory 2009 to 2014.

OBJECTIVE: To determine whether cases of congenital syphilis in the Northern Territory between 2009 and 2014 were correctly notified based on probable or confirmed case criteria stipulated by the Communicable Diseases Network Australia (CDNA). METHODS: Pregnant women with positive syphilis serology defined as reactive treponemal test and rapid plasma reagin titre ≥1:8 were identified from the Northern Territory Syphilis Register Information System. Risk classification was performed based on local guidelines, and CDNA criteria for probable/confirmed cases of congenital syphilis were applied to determine whether cases were appropriately notified. RESULTS: Thirty-four cases of positive maternal syphilis serology in pregnancy were identified from 31 women; all were Indigenous. Twenty-one cases fulfilled criteria for probable congenital syphilis; 1 case was formally notified to the Centre for Disease Control. Twenty cases (95%) fulfilling CDNA criteria for probable congenital syphilis were not notified over the study period. CONCLUSIONS: Application of standard case definitions significantly increases the rate of congenital syphilis cases in the Northern Territory. Improved education regarding CDNA criteria for notification of congenital syphilis is necessary for clinicians and public health staff. Emerging evidence has supported the recent simplification of CDNA criteria for notification of congenital syphilis, effective 1 July 2015.

A cross sectional study of how people diagnosed with a bacterial sexually transmitted infection inform their partners.

OBJECTIVES: To investigate the methods used by patients diagnosed with a sexually transmissible infection (STI) to inform their partners during contact tracing. METHODS: At a large Australian sexual health clinic between March and May 2010, we undertook a retrospective, cross sectional analysis of the methods used by patients diagnosed with a bacterial STI to inform their partners. RESULTS: Of the 172 index patients contacted 1 week after treatment, 163 (95%) chose patient referral, 3 (2%) provider referral and 6 (3%) could not contact any partners. Index patients nominated 1010 sexual partners of whom 494 (49%) were reported as contactable. A total of 447/494 (91%) of these partners were successfully informed; telephone (37%) and face to face (22%) were the most used methods. After multivariate analysis, predictors of using face to face contact methods were age <30 years (AOR: 2.8; 95% CI 1.4 to 5.7), fewer than 2 sexual partners (AOR 3.6; 95% CI 1.7 to 7.6) and speaking a language other than English (adjusted OR (AOR) 3.1; 95% CI 1.3 to 7.2). The single predictor of using interactive contact methods (face to face+telephone) was reporting fewer than 2 sexual partners (AOR 2.7; 95% CI 1.3 to 5.5). People diagnosed with syphilis were significantly less likely to use an interactive contact tracing method (AOR 0.24; 95% CI 0.09 to 0.67). CONCLUSIONS: Most patients diagnosed with a bacterial STI at our sexual health clinic report informing their contactable partners directly either face to face or by telephone. Electronic communications methods were more popular for people with more sexual partners and those with syphilis. Effective contact tracing requires access to a range of methods for patients to inform their partners.

New Xpress sexually transmissible infection screening clinic improves patient journey and clinic capacity at a large sexual health clinic.

INTRODUCTION: In December 2010, a new "express" testing service (Xpress) was implemented alongside routine clinics at a large sexual health clinic. Xpress involved a computer-assisted self-interview, self-collected samples and enrolled nurse staffing. We evaluated the impact of the service on patient journey, staff costs, and clinical capacity. METHODS: In the first 5 months of Xpress, we calculated the median waiting time and length of stay, staff hours and costs, and utilization. We compared these attributes to the same months in the previous year. RESULTS: In the Xpress period, 5335 patients were seen (705 in the Xpress clinic, 4630 in routine clinic), 11% more than the 4804 in the before period. Staff hours were 13% greater in the Xpress period compared with the before period (3567 vs. 3151). The cost per patient seen in the Xpress period was lower compared with the before period ($26.79 compared with $28.48). The median waiting time in the Xpress period was 19 minutes (interquartile range, 8-36; 10 in Xpress clinic and 17 in routine clinics) compared with 23 in the before period (P < 0.01). The median length of stay in the Xpress period was 40 minutes (interquartile range, 27-58; 21 in Xpress clinic and 40 in routine clinics) compared with 43 in the before period (P < 0.01). The utilization rates were 67% in the Xpress period (40% in the Xpress clinic and 74% in routine clinics) compared with 76% in the before period (P < 0.01). CONCLUSION: The Xpress clinic improved the patient journey, and although not fully used, more patients were seen overall in the clinic with minimal additional costs. Marketing of the Xpress clinic is underway.

Client feedback and satisfaction with an express sexually transmissible infection screening service at an inner-city sexual health center.

BACKGROUND: Sydney Sexual Health Centre (SSHC) commenced a fast-track sexually transmissible infection clinic, the Xpress Clinic (Xpress) pilot for asymptomatic clients in March 2010, using a computer-assisted self-interview and self-collected samples. This study examines client satisfaction and changes in intended screening frequency among clients of Xpress. METHODS: This was a cross-sectional study of all clients attending Xpress clinics during the initial 6 months. All clients were requested to complete a survey based on a previously validated questionnaire. Results were stratified by sex, sex of sexual partners, age, and sex work status. RESULTS: Of the 243 clients who attended Xpress, 145 (60%) returned questionnaires. The 2 most common reasons for choosing Xpress clinic were reduced waiting time (n = 42/138 [30%]; 95% confidence interval [CI], 23%-38%) and reduced length of consultation (n = 16/138 [12%]; 95% CI, 7%-17%).When asked if they would have come to SSHC anyway if Xpress was not an option, men who have sex with men (MSM) were more likely than non-MSM to say that they would come for screening anyway (77% MSM vs. 59% non-MSM, P = 0.034). Youth younger than 25 were less likely than those 25 years and older to have come for screening anyway (53% vs. 79%, P = 0.012).Most (n = 101/138 [73%]; 95% CI, 65%-80%) considered that they would test for sexually transmissible infections more frequently in the future using the Xpress model. Client satisfaction levels were high, with most respondents reporting that they would return to Xpress (n = 119/142 [83%]; 95% CI, 77%-89%) and would recommend it to friends (n = 122/142 [86%]; 95% CI, 79%-90%). CONCLUSIONS: Most clients were highly satisfied with all aspects of Xpress and reported intentions to retest using this model of care.

Increasing access by priority populations to Australian sexual health clinics.

Data from a network of 35 Australian sexual health clinics, in geographically diverse locations, showed that the number and proportion of patients from priority populations (ie, young people, men who have sex with men, indigenous people, and female sex workers) increased significantly between 2004 and 2011.

Renal impairment associated with tenofovir disoproxil fumarate for antiretroviral therapy and HIV pre-exposure prophylaxis: An observational cohort study.

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is associated with adverse renal outcomes when prescribed for HIV infection. There are few data concerning real-world renal outcomes amongst patients prescribed TDF for pre-exposure prophylaxis (PrEP). METHODS AND FINDINGS: Data were extracted from 52 sexual health clinics across Australia from 2009-2019. All patients prescribed TDF-containing antiretroviral therapy and PrEP were included. Rates of renal impairment (a fall in eGFR to <60 ml/min/1·73m2) were calculated for people living with HIV (PLWHIV) prescribed TDF and HIV negative PrEP-users. Risk factors were assessed using Cox-proportional hazards models. Sensitivity analysis of risk using 1:1 propensity-score matching to adjust for potential imbalance in HIV and PrEP cohorts was conducted. 5,973 patients on PrEP and 1,973 PLWHIV were included. There were 39 (0.7%) instances of renal impairment in the PrEP group and 81 (4.1%) in the PLWHIV cohort (hazard ratio [HR]:0.35 95% confidence interval [CI]: 0.22-0.56). Rates of renal impairment were 4.01/1000 person-years (95%CI:2.93-5.48) in the PrEP cohort and 16.18/1000 person-years (95%CI:13.01-20.11) in the PLWHIV cohort (p<0.001). Predictors of renal impairment were: older age (40-49 years (HR:5.09 95%CI: 2.12-12.17) and 50-82 years (HR:13.69 95%CI: 5.92-31.67) (compared with 30-39 years) and baseline eGFR<90ml/min (HR:61.19 95%CI: 19.27-194.30). After adjusting for age and baseline eGFR the rate of renal impairment remained lower in the PrEP cohort (aHR:0.62 95%CI: 0.40-0.94, p = 0.023). In propensity-matched analysis using 1,622 patients per cohort the risk of renal impairment remained higher in the PLWHIV cohort (log-rank p = 0.001). CONCLUSION: Patients prescribed TDF-based PrEP had lower rates of renal impairment than patients prescribed TDF for HIV infection. In propensity analysis, after matching for some risk factors, rates of renal impairment remained higher amongst patients with HIV.
