Testing for HIV among men who have sex with men needs a paradigm shift in Australia, given the minimal increase between 2003 and 2013 in Melbourne, Australia

Trends and associated factors in HIV testing among heterosexual men and women in Melbourne, Australia, 2011-2020

BACKGROUND

Despite the increase in the proportion of HIV notifications attributed to heterosexuals in Australia, little is known about their HIV testing behaviours. We investigated the trends and factors associated with HIV testing behaviours among heterosexuals.

METHODS

We analysed the trend and proportion of heterosexuals attending the centre for the first time between 2011 and 2020, who had ever tested and tested for HIV in the past 12months and the median number of months since their last HIV test. We identified factors associated with HIV testing behaviours using univariable and multivariable logistic regressions.

RESULTS

Of the 78652 heterosexuals included, 53.1% were men and 46.9% were women. Overall, the proportion of heterosexuals who had ever tested for HIV was 40.8%, with a declining testing trend from 40.2% in 2011 to 36.5% in 2020 (P trend <0.001). Overall, the proportion of heterosexuals tested for HIV in the past 12months was 15.7%, with no significant change from 15.3% in 2011 to 14.7% in 2020 (P trend =0.489). The median number of months since the last HIV test decreased from 18.0 (IQR 6.9-37.3) in 2011 to 15.0 (IQR 6.4-32.5) in 2020 (P trend <0.001). Individuals who had condomless sex with casual partners (aOR 0.92, 95% CI 0.88-0.96) and who were diagnosed with a sexually transmitted infection (aOR 0.88, 95% CI 0.84-0.93) were less likely to have ever tested for HIV.

CONCLUSIONS

HIV testing was low among heterosexuals, and individuals who engaged in condomless sex and had another sexually transmitted infection were less likely to be tested. To reduce HIV transmission, strategies to improve HIV testing among heterosexuals are needed.

Implications of HIV Self-Testing for Other Sexually Transmissible Infection Testing and Broader Sexual Health Needs: A Mixed-Methods Study of Gay and Bisexual Men in Australia

BACKGROUND

Although HIV self-tests can support frequent HIV testing, their impact on attending clinics for other sexually transmissible infection (STI) testing and sexual health care is largely unknown. We explored intentions to use HIV self-tests and how this might affect patterns of attending sexual health services among gay, bisexual, and other men who have sex with men (GBM) in Victoria, Australia.

METHODS

Gay, bisexual, and other men who have sex with men self-completed an online survey between March 10 and June 10, 2019. Among GBM reporting lifetime HIV testing and intentions to self-test at least once annually, we used logistic regression to identify correlates of intending to replace clinic-based HIV testing with self-tests. Qualitative interviews with purposively selected survey participants undertaken between May and June 2019 explored the implications of self-testing on clinic-based sexual health care.

RESULTS

Of the 279 survey participants, 79 (29%) reported they would replace most or all clinic-based HIV tests with self-tests, with longer time since last testing for HIV and younger age associated with reporting this outcome in the multivariate analysis. Qualitative interviews revealed different perceived roles for self-tests and clinic-based testing, and the importance of integrating HIV self-tests within broader sexual health routines.

CONCLUSIONS

Although GBM see a distinct role for HIV self-testing, its rollout will likely result in missed opportunities for clinic-based STI testing and education for some GBM, particularly among younger and less-recently tested GBM. Convenient, non-clinic-based approaches to STI testing are needed alongside support platforms to maximize the benefits of HIV self-testing within comprehensive sexual health routines.

HIV Testing With and Without a Clinical Consultation Among Men Who Have Sex With Men: A Randomized Controlled Trial

BACKGROUND

Increasing the frequency of HIV testing among men who have sex with men (MSM) maximizes the preventive effect of antiretroviral therapy, by reducing time to diagnosis and treatment.

SETTING

Melbourne Sexual Health Centre, Australia.

METHODS

This randomized controlled trial evaluated whether access to testing, without seeing a clinician would increase testing frequency. MSM attending for HIV testing between July 2014 and April 2015 were randomized in 1:1 ratio to the intervention arm (access to HIV and syphilis testing at 300 pathology centers, without requiring consultations) or the control arm (consultation at every test), without blinding. The primary outcome was the incidence of HIV testing over 12 months.

RESULTS

Of 443 men referred, 422 were randomized, 3 HIV positives at baseline were excluded, and 419 were analyzed. Of 208 control, 202 (97.1%) and 200 (94.8%) of 211 intervention group members were followed to 12 months. The intervention group had 453 tests in 205.6 person-years, incidence rate was 2.2 (95% confidence interval [CI]: 2.0 to 2.4) tests per year. The control group had 432 tests during 204.0 person-years, incidence rate was 2.1 (95% CI: 1.9 to 2.3) tests per year, and incidence rate ratio was 1.04 (95% CI: 0.89 to 1.2; P = 0.63). The annual rate of consultations was as follows: intervention, 1.61 (95% CI: 1.44 to 1.79); controls, 2.12 (95% CI: 1.92 to 2.33); rate ratio, 0.76 (95% CI: 0.65 to 0.88; P = 0.0001). There was no difference in quality of life scores (P = 0.61).

CONCLUSIONS

MSM permitted HIV and syphilis testing outside of clinical consultations did not test more frequently than controls but had 24% fewer consultations, reducing service demand.

Trends and predictors of recent HIV testing over 22 years among a clinic sample of men who have sex with men in South Australia

Increasing the frequency of HIV testing is crucial for effective HIV prevention and care. The aim of the present study was to determine whether there has been a change in HIV testing among men who have sex with men (MSM) at the South Australia Specialist Sexual Health (SASSH) clinic over the past two decades.

METHODS

Computerised medical records of MSM who attended the SASSH at their first visit between 1994 and 2015 were used to determine whether HIV testing had changed among MSM. First HIV tests in each calendar year and return tests within 12 months were analysed. Factors associated with recent HIV testing were also examined.

RESULTS

There were 24036 HIV tests conducted among 8163 individual MSM over the study period. The proportion of newly registered MSM who reported ever being tested for HIV declined (P_trend=0.030), the proportion who reported recent HIV testing did not change (P_trend=0.955) and the proportion who have had current HIV testing increased (P_trend=0.008). The proportion of MSM who returned to the clinic for HIV testing within 12 months did not change (P_trend >0.05), with less than 40% of MSM returning for HIV testing. Factors independently associated with recent HIV testing included MSM aged ≥20 years, (odds ratio (OR) 1.79; 95% confidence interval (CI) 1.53-2.10), higher education (OR 1.28; 95% CI 1.12-1.45), non-Caucasian (African OR 1.68; 95% CI 1.30-2.17), having multiple sex partners (OR 1.47; 95% CI 1.29-1.69), having had sex interstate (OR 1.61; 95% CI 1.42-1.82) or overseas (OR 1.53; 95% CI 1.33-1.76) and injecting drug use (OR 1.56; 95% CI 1.29-1.88).

CONCLUSIONS

HIV testing rate among MSM attending SASSH was suboptimal. New approaches are needed to increase the uptake and early detection of HIV infection among the high-priority MSM population.

Understanding the Targeting and Uptake of HIV Testing Among Gay and Bisexual Men Attending Sexual Health Clinics

We assessed trends in HIV testing outcomes during a period of clinic-based initiatives introduced to increase HIV testing among gay and bisexual men (GBM) attending sexual health clinics (SHCs) in New South Wales (NSW). A cohort of 25,487 HIV-negative GBM attending 32 SHCs in NSW (2009-2015) was classified into six sub-groups each year based on client-type (new/existing), risk-status (low/high-risk), and any recent HIV testing. Poisson regression methods were used to assess HIV testing outcomes in sub-groups of GBM. HIV testing outcomes and the sub-groups with greatest statistically significant annual increases were: individuals attending (26% in high-risk existing clients with recent testing); testing uptake (4% in low-risk existing clients with no recent testing); testing frequency (6% in low-risk existing clients with no recent testing and 5% in high-risk existing clients with recent testing); and total tests (31% in high-risk existing clients with recent testing). High-risk existing clients with recent testing had a 13% annual increase in the proportional contribution to total tests. Our findings show improved targeting of testing to high-risk GBM at NSW SHCs. The clinic-based initiatives should be considered for translation to other similar settings.

Acceptability and HIV Prevention Benefits of a Peer-Based Model of Rapid Point of Care HIV Testing for Australian Gay, Bisexual and Other Men Who Have Sex with Men

Frequent HIV testing among gay, bisexual and other men who have sex with men (GBM) is a strategic priority for HIV prevention in Australia. To overcome barriers to testing in conventional clinical services, Australia recently introduced peer HIV rapid point of care (RPOC) testing services for GBM. This mixed methods evaluation describes client acceptability and HIV prevention benefits of a peer HIV testing model. Most aspects of the service model were overwhelmingly acceptable to clients. Two-thirds of survey participants reported preferring testing with peers rather than doctors or nurses and over half reported learning something new about reducing HIV risk. Focus group findings suggested peer-delivered HIV RPOC testing reduced stigma-related barriers to frequent testing and provided novel opportunities for GBM to openly discuss HIV prevention and sexual practices, enhancing their HIV risk-reduction knowledge. Analysis of survey data suggested knowledge transfer occurred particularly among younger and less gay community-attached GBM.

Time from HIV infection to virological suppression: dramatic fall from 2007 to 2016

AIM

Time from HIV infection to virological suppression: dramatic fall from 2007 to 2016.

OBJECTIVES

We examined the time from HIV infection to virological suppression in MSM who were first diagnosed at Melbourne Sexual Health Centre between 2007 and 2016.

DESIGN

Retrospective cohort.

METHODS

Date of infection was imputed from the testing history or serological evidence of recent infection (negative or indeterminate western blot) or baseline CD4 cell count. Date of virological suppression was determined using clinical viral load data. We analysed predictors of diagnosis with serological evidence of recent infection (logistic regression) and time from diagnosis to suppression and from infection to suppression (Cox regression) using demographic, clinical, and behavioral covariates.

RESULTS

Between 2007 and 2016, the median time from HIV infection to diagnosis fell from 6.8 to 4.3 months (P = 0.001), from diagnosis to suppression fell from 22.7 to 3.2 months (P < 0.0001), and from infection to suppression fell from 49.0 to 9.6 months (P < 0.0001). Serological evidence of recent infection increased from 15.6 to 34.3% (P < 0.0001) of diagnoses. In the multivariate analyses, age, being recently arrived from a non-English speaking country, history of IDU, other sexually transmitted infections, and sexual risk were not associated with any of these measures.

CONCLUSION

The duration of infectiousness in MSM diagnosed with HIV infection at Melbourne Sexual Health Centre in Victoria has fallen dramatically between 2007 and 2016 and the proportion diagnosed with serological evidence of recent infection has increased. This effect is observed across all population subgroups and marks a positive milestone for the treatment as prevention paradigm.

Increasing HIV testing among hard-to-reach groups: examination of RAPID, a community-based testing service in Queensland, Australia

Background

The success of ‘treatment as prevention’ (TasP) to control HIV relies on the uptake of testing across priority population groups. Innovative strategies including; rapid HIV testing (RHT) in community and outreach settings, engaging peer service providers, and not requiring disclosure of sexual history have been designed to increase access. This paper reports on the implementation of ‘RAPID’, a community-based testing program in Queensland, Australia that employs these strategies to increase access to testing.

Methods

Service data, including client registration forms and a satisfaction survey from all clients attending RAPID between August 2014 and July 2015 were analysed.

Results

In 2014/2015 1,199 people attended RAPID to receive a free HIV test. The majority were urban-based gay men. 17.1% were first-time testers and 20.1% of participants were not eligible to access Medicare, Australia’s universal health care scheme.

Conclusions

RAPID’s evidence-based strategies appear to facilitate access to HIV testing, particularly among those who have never tested before; however the implications for the ongoing treatment and care of people ineligible for Medicare, who test positive to HIV warrants careful consideration.
