RESUMO

BACKGROUND: Dried blood spot (DBS) testing provides an alternative to phlebotomy and addresses barriers to accessing healthcare experienced by some key populations. Large-scale evaluations of DBS testing programs are needed to understand their feasibility. This study evaluated the implementation of a state-wide DBS HIV and hepatitis C virus (HCV) testing pilot. METHODS: The New South Wales (NSW) DBS Pilot is an interventional cohort study of people testing for HIV antibody and/or HCV RNA from DBS samples in NSW, Australia. Participants at risk of HIV/HCV participated in testing via: 1) self-registration online with a DBS collection kit delivered and returned by conventional postal service; or 2) assisted DBS sample collection at 36 community health sites (including drug treatment and harm-minimisation services) and prisons. Participants received results by text (HIV antibody/ HCV RNA not detected) or a healthcare provider (HIV antibody/ HCV RNA detected). The RE-AIM framework was used to evaluate reach, effectiveness, adoption, and implementation. RESULTS: Reach: Between November 2016 and December 2020, 7,392 individuals were tested for HIV and/or HCV (21% self-registration, 34% assisted in community, and 45% assisted in prison). EFFECTIVENESS: Of 6,922 people tested for HIV (19% men who have sex with men, 13% living outside major cities, 21% born outside Australia), 51% (3,521/6,922) had no HIV test in the past two years, 0.1% (10/6,922) were newly diagnosed with HIV, and 80% (8/10) initiated HIV treatment within six months. Of 5,960 people tested for HCV (24% women, 35% Aboriginal and/or Torres Strait Islander, 55% recently injected drugs), 15% had detectable HCV RNA (878/5,960), and 45% (393/878) initiated treatment within six months. Adoption: By the end of 2020, DBS via assisted registration was available at 36 community sites and 21 prisons. IMPLEMENTATION: 90% of DBS cards arriving at the laboratory had the three full spots required for testing; the proportion was higher in assisted (94%) compared to online (76%) registration. CONCLUSIONS: This study demonstrated the feasibility of DBS testing for HIV and HCV in key populations including Aboriginal and Torres Strait Islander peoples, men who have sex with men, people who inject drugs, and demonstrated the utility of DBS in the prison setting.

RESUMO

Background: Dried blood spot (DBS) testing for hepatitis C virus (HCV) RNA provides a sampling option that avoids venepuncture and can be carried out in a nonclinical setting. Large-scale evaluations are needed to understand how DBS testing can reduce HCV burden. This study estimated prevalence of, and factors associated with, HCV RNA and treatment initiation among people enrolled in a state-wide pilot of people testing in the NSW DBS Pilot in New South Wales, Australia. Methods: People at risk of HIV/HCV could participate via (1) self-registration online with a DBS collection kit delivered and returned by conventional postal service; or (2) assisted DBS sample collection at a community site or prison. Logistic regression was used to identify factors associated with detectable HCV RNA and treatment initiation within 6 months of testing. Results: Between September 2017 and December 2020, 5960 people were tested for HCV (76% men, 35% Aboriginal and/or Torres Strait Islander, 55% recently injected drugs): 21% online self-registration, 34% assisted registration in the community, 45% assisted registration in prison. Fifteen percent had detectable HCV RNA (878/5960). Overall, 44% (n = 386/878) of people with current HCV initiated treatment within 6 months (13% online self-registration, 27% assisted registration in the community, 61% assisted registration in prison). Testing in prison compared with the community (adjusted odds ratio [aOR], 4.28; 95% CI, 3.04-6.03) was associated with increased odds of treatment initiation. Being a woman compared with a man (aOR, 0.68; 95% CI, 0.47-0.97) was associated with reduced treatment initiation. Conclusions: The NSW DBS Pilot demonstrates the feasibility of using DBS to promote HCV testing and treatment in community and prison settings.

RESUMO

BACKGROUND: The Undetectable=Untransmittable (U=U) message has been promoted since it was demonstrated that viral suppression through HIV treatment prevents sexual transmission between serodiscordant partners (HIV treatment as prevention). Our study assessed familiarity with, perceived accuracy of, and willingness to rely on U=U in a national sample of gay and bisexual men in Australia. METHODS: We conducted a national, online cross-sectional survey in April-June 2021. Eligible participants were gay, bisexual and queer men and non-binary people who lived in Australia. Logistic regression was used to identify factors associated with familiarity, perceived accuracy and willingness to rely on U=U (by having condomless sex with a partner with HIV who has an undetectable viral load). RESULTS: Of 1280 participants, most were familiar with U=U (1006/1280; 78.6%), the majority of whom believed U=U was accurate (677/1006; 67.3%). Both familiarity and perceived accuracy were higher among participants living with HIV, followed by pre-exposure prophylaxis (PrEP) users, HIV-negative participants not taking PrEP, and untested/unknown status participants. Knowing at least one person living with HIV, among other factors, was associated with familiarity and perceived accuracy of U=U; and familiarity was associated with perceived accuracy. Among participants familiar with U=U, less than half were willing to rely on U=U (473/1006; 47.0%). Familiarity with U=U and knowing at least one person living with HIV were associated with willingness to rely on U=U, among other factors. CONCLUSIONS: We found familiarity with U=U was associated with perceived accuracy and willingness to rely upon it. There is an ongoing need to educate gay and bisexual men (particularly HIV-negative men) about U=U and its benefits.

RESUMO

Relationship agreements are important for HIV prevention among gay and bisexual men (GBM) in relationships, with research earlier in the HIV epidemic often finding that agreements specified monogamy or condom use with casual partners. There is evidence that HIV pre-exposure prophylaxis (PrEP) has shifted sexual practices among some men in relationships, such as allowing condomless sex with casual partners, but there has been little attention paid to relationship agreements among GBM who use PrEP. In this paper, we analyzed national, Australian, cross-sectional data from an online survey completed by non-HIV-positive GBM in 2021 (N = 1,185). Using logistic regression, we identified demographic characteristics, sexual practices and the types of relationship agreement that were associated with PrEP use among GBM in relationships. Using Pearson's chi-squared tests, we explored whether PrEP users in relationships reported similar sexual practices to PrEP users not in relationships. PrEP use among GBM in relationships was independently associated with older age, identifying as gay, being in a non-monogamous relationship, having a spoken (explicit) relationship agreement, having a primary HIV-negative partner taking PrEP or a primary partner living with HIV, reporting recent condomless casual sex, reporting an STI diagnosis in the past year, and knowing at least one other PrEP user. We found that PrEP users in relationships had similar sexual practices to PrEP users not in relationships. GBM in relationships who have casual sex and who meet PrEP suitability criteria may be good candidates for PrEP. Our findings suggest that explicit relationship agreements remain important for HIV prevention, and they support PrEP use among GBM in relationships.

RESUMO

Condoms have been the primary form of HIV prevention for gay and bisexual men (GBM) for most of the HIV epidemic. The introduction of biomedical HIV prevention may have changed attitudes towards condoms. Data from repeated national online surveys of GBM in Australia were used to examine how attitudes towards condoms and confidence discussing condoms with partners changed in the period 2011-2019. The proportion of all participants who reported a positive experience in using condoms remained low and unchanged (9.6% in 2011 to 6.0% in 2019). Confidence in discussing condoms with partners decreased over time (from 72.2% in 2011 to 56.6% in 2019). Confidence in discussing condoms was associated with concern about sexually transmitted infections, and more consistent condom use. Sustaining confidence in using condoms may be more challenging as biomedical prevention methods become more commonly used.

RESUMO

Gay and bisexual migrants from low- and middle-income countries living in high-income countries are disproportionately diagnosed with HIV. Most research focuses on preventing HIV acquisition among HIV-negative migrant gay and bisexual men (GBM). This study is uniquely positioned to report on migrant GBM's experiences and needs at and after an HIV diagnosis. Semi-structured interviews were conducted with 24 migrant GBM diagnosed at sexual health clinics in Australia from 2017 onwards. Interviews were analysed using a codebook thematic analysis. Due to the stigma of HIV and homosexuality in their countries of origin, about half of participants had poor HIV knowledge prior to diagnosis. Absorbing diagnosis information was consequently difficult, and feelings of shame, hopelessness, lost sexual opportunities and infectiousness were common. However, many were thankful for the comprehensive clinical support they received and believed that over time life would 'normalise' with sustained undetectable viral load. None reported that their clinician stigmatised them, but the anticipation of stigma nonetheless infused their experiences after diagnosis. Many were selective about HIV disclosure, and some mentioned that clinic systems posed a risk to confidentiality. Non-permanent residents were concerned about the impacts of HIV status on future visa applications. We recommend that newly HIV-diagnosed migrant GBM receive referral to legal and culturally appropriate migration services to help absorb what a diagnosis might mean for their health and visa status. We also recommend sexual health clinics continue to assess confidentiality in their systems. Health promotion initiatives should highlight to migrant GBM that high-HIV caseload sexual health clinicians provide confidential and comprehensive care.

RESUMO

Minority groups may face additional barriers to vaccination. In April-June 2021, we assessed the level of COVID-19 vaccination and willingness to be vaccinated in a national, online survey of 1280 gay and bisexual men in Australia. Over a quarter of the sample (28.0%) had been partially or fully vaccinated, and 80.0% of the unvaccinated were willing to be vaccinated. Vaccination was independently associated with older age, being university educated, and HIV status (with HIV-positive participants being more likely and untested participants less likely to be vaccinated). Willingness to be vaccinated was independently associated with living in a capital city and being university educated. Those who had lost income or their job due to COVID-19 were less willing to be vaccinated. Our results suggest encouraging COVID-19 vaccination among those with lower levels of health literacy and supporting those who have experienced financial stress because of the pandemic.


RESUMEN: Los grupos minoritarios pueden enfrentar barreras adicionales accediendo a una vacuna. En abril-junio de 2021, evaluamos el nivel de vacunación contra el COVID-19 y la disposición a la vacuna utilizando datos de una encuesta nacional en línea de 1280 hombres gays y bisexuales en Australia. El 28% de los participantes habían sido vacunados parcial o totalmente, y el 80% de los no vacunados estaban dispuestos a vacunarse. La vacunación se asoció de forma independiente con participantes de mayor edad, con educación universitaria y su estado de VIH (los participantes VIH positivos tenían más probabilidades que los participantes sin prueba del VIH de ser vacunados). La disposición a favor de ser vacunados se asoció de manera independiente con vivir en una ciudad capital y tener estudios universitarios. Aquellos que habían perdido ingresos o su trabajo debido al COVID-19 estaban menos dispuestos a vacunarse. Nuestros hallazgos sugieren que es importante promover la vacunación contra el COVID-19 entre personas que tienen menos información en temas de salud y apoyar a quienes han sufrido estrés financiero debido a la pandemia.

RESUMO

Background Overseas-born people who are ineligible for government-subsidised health care experience barriers to accessing HIV pre-exposure prophylaxis (PrEP) in Australia. This study aimed to assess a program providing free PrEP to overseas-born adults at risk of acquiring HIV. Methods Medicare-Ineligible Expanded Implementation in Communities (MI-EPIC) was a single-arm, open-label trial of daily tenofovir disoproxil fumarate/emtricitabine as PrEP. Six clinics recruited Medicare-ineligible adults who met HIV risk criteria in New South Wales, Australia. We recorded data on HIV and sexually transmitted infection (STI) diagnoses, and PrEP dispensing from July 2019 to June 2020. PrEP adherence as a medication possession ratio (MPR) was calculated as pills dispensed divided by days. We administered an optional survey on behaviours and attitudes to PrEP and sexual health. Results The 221 participants (206 men; 93.2%) had a median age of 29years (IQR 26-34). Participants were mostly born in Asia (53.4%), Latin America or the Caribbean (25.3%), or Europe (10.9%). Adherence was high; 190 participants (86.0%) had an MPR of >60%. Of 121 survey participants, 42 (34.7%) completed the survey in a language other than English. Of participants who had not used PrEP in the 6months before enrolment (n=45, 37.2%), the most common reasons were cost (n=22, 48.9%), and lack of knowledge about accessing PrEP (n=20, 44.4%). Conclusions Medicare-ineligible people at risk of HIV demonstrate high adherence when given access to free PrEP and translated information. Increasing PrEP awareness and reducing barriers to accessing PrEP in this high-risk population should be priorities in HIV prevention.

RESUMO

BACKGROUND: Daily pre-exposure prophylaxis (PrEP) is effective in preventing HIV, but few long-term data are available on effectiveness and adherence in real-world settings. Here, we report trends in HIV incidence over 3 years in individuals at high risk who were prescribed PrEP in New South Wales (NSW), as well as adherence before the transition to subsidised PrEP. METHODS: Expanded PrEP Implementation in Communities-New South Wales (EPIC-NSW) was a pragmatic, prospective, single-arm, implementation study of daily, oral PrEP in 31 sites (sexual health clinics, general practices, and a hospital) in NSW, Australia. Eligible participants were HIV-negative adults (aged ≥18 years) who were at high risk of HIV infection as defined in local PrEP guidelines. Participants were prescribed coformulated (once-daily, oral tablet) tenofovir disoproxil fumarate (300 mg) and emtricitabine (200 mg) as HIV PrEP and were followed up with HIV testing, sexually transmitted infection testing, and PrEP dispensing. Originally planned for 3700 participants followed for 1 year, the study was expanded so that all eligible participants in the state could obtain PrEP and extended until publicly subsidised PrEP became available in Australia. The primary outcome was new HIV infection among all participants who were dispensed PrEP at least once and had at least one follow-up HIV test result. Adherence was estimated by medication possession ratio (MPR), defined as the proportion of PrEP pills dispensed in 90 days, assuming daily dosing. This study is registered with ClinicalTrials.gov, NCT02870790. FINDINGS: Between March 1, 2016, and April 30, 2018, we enrolled 9709 participants. 9596 participants were dispensed PrEP, of whom 9448 (98·3%) were gay or bisexual men. Participants were followed up until March 31, 2019, with at least one follow-up HIV test available in 9520 (99·2%) participants. Mean MPR declined from 0·93 to 0·64 from the first to the ninth quarter. There were 30 HIV seroconversions over 18 628 person-years, an incidence of 1·61 per 1000 person-years (95% CI 1·13-2·30). Being younger, living in a postcode with fewer gay men, reporting more risk behaviours at baseline, and having an MPR of less than 0·6 were each univariately associated with increased HIV incidence. In the final year of follow-up, when PrEP was mostly purchased rather than provided free by the study, HIV incidence remained low at 2·24 per 1000 person-years (1·46-3·44). INTERPRETATION: HIV incidence remained low over up to 3 years of follow-up, including during a transition from study-provided to publicly subsidised PrEP. In a setting of affordable PrEP and associated health-care services, very low HIV incidence of 1 to 2 per 1000 person-years can be maintained in gay and bisexual men who were previously at high risk.

RESUMO

We have tracked belief in the effectiveness of HIV treatment as prevention (TasP) among Australian gay and bisexual men (GBM) since 2013. National, online cross-sectional surveys of GBM were conducted every 2 years during 2013-2019. Trends and associations were analyzed using multivariate logistic regression. Data from 4,903 survey responses were included. Belief that HIV treatment prevents transmission increased from 2.6% in 2013 to 34.6% in 2019. Belief in the effectiveness of TasP was consistently higher among HIV-positive participants than other participants. In 2019, higher levels of belief in TasP were independently associated with university education, being HIV-positive, using pre-exposure prophylaxis, knowing more HIV-positive people, being recently diagnosed with a sexually transmitted infection (STI) and use of post-exposure prophylaxis. Belief that HIV treatment prevents transmission has increased substantially among Australian GBM, but remains concentrated among HIV-positive GBM, those who know HIV-positive people, and GBM who use antiretroviral-based prevention.

RESUMO

BACKGROUND: We assessed willingness to use HIV pre-exposure prophylaxis (PrEP) and current PrEP use among gay and bisexual men (GBM) in Australia. METHODS: National, online cross-sectional surveys of GBM were conducted in 2013, 2015, 2017, and 2019. Willingness to use PrEP was measured on a previously validated scale. Trends and associations with key measures were analyzed using multivariate logistic regression. RESULTS: During 2013-2019, 4908 surveys were completed. Among HIV-negative and untested men not currently using PrEP, willingness to use PrEP increased from 23.0% in 2013 to 36.5% in 2017 (P < 0.001) but then plateaued at 32% in 2019 (P = 0.13). The proportion of current PrEP users increased significantly from 2.5% in 2015 to 38.5% in 2019 (P < 0.001). In 2019, factors independently associated with being a current PrEP user (compared with non-PrEP users who were willing to use PrEP) included having subsidized health care (Medicare), knowing HIV-positive people, being recently diagnosed with an STI other than HIV, having higher numbers of recent male sexual partners, recent condomless sex with casual and regular partners, and frequent PrEP sorting. CONCLUSION: Willingness to use PrEP has plateaued as its use has rapidly increased among GBM in Australia. PrEP use is concentrated among more sexually active men with access to subsidized health care. Free or low cost access schemes may facilitate broader access among GBM who want or need PrEP but lack access to subsidized health care.

RESUMO

BACKGROUND: HIV prevention cascades can assist in monitoring the implementation of prevention methods like preexposure prophylaxis (PrEP). We developed 2 PrEP cascades for Australia's primary HIV-affected population, gay and bisexual men. METHODS: Data were drawn from 2 national, repeated, cross-sectional surveys (the Gay Community Periodic Surveys and PrEPARE Project). One cascade had 3 steps, and the other had 7 steps. Trends over time were assessed using logistic regression. For the most recent year, we identified the biggest drop between steps in each cascade and compared the characteristics of men between the 2 steps using multivariate logistic regression. RESULTS: Thirty-nine thousand six hundred and seventy non-HIV-positive men participated in the Periodic Surveys during 2014-2018. PrEP eligibility increased from 28.1% (1901/6762) in 2014 to 37.3% (2935/7878) in 2018 (P < 0.001), awareness increased from 29.6% (563/1901) to 87.1% (2555/2935; P < 0.001), and PrEP use increased from 3.7% (21/563) to 45.2% (1155/2555; P < 0.001). Of 1038 non-HIV-positive men in the PrEPARE Project in 2017, 54.2% (n = 563) were eligible for PrEP, 97.2% (547/563) were aware, 67.6% (370/547) were willing to use PrEP, 73.5% (272/370) had discussed PrEP with a doctor, 78.3% (213/272) were using PrEP, 97.2% (207/213) had recently tested, and 75.8% (157/207) reported reduced HIV concern and increased pleasure because of PrEP. The break point analyses indicated that PrEP coverage was affected by geographical availability, education level, employment, and willingness to use PrEP. CONCLUSIONS: PrEP eligibility, awareness, and use have rapidly increased among Australian gay and bisexual men. The cascades identify disparities in uptake by eligible men as a result of socioeconomic factors and PrEP's acceptability.

RESUMO

Subsidized direct-acting antiviral (DAA) treatment recently became available to all adults living with chronic hepatitis C virus (HCV) in Australia. Based on rapid uptake (32 600 people initiated DAA in 2016), we estimated the impact on HCV epidemiology and mortality in Australia and determined if Australia can meet the WHO HCV elimination targets by 2030. Using a mathematical model, we simulated pessimistic, intermediate and optimistic DAA treatment scenarios in Australia over 2016-2030. We assumed treatment and testing rates were initially higher for advanced fibrosis and the same across HCV transmission risk level sub-populations. We also assumed constant testing rates after 2016. We compared the results to the 2015 level and a counterfactual (IFN-based) scenario. During 2016-2030, we estimated an intermediate DAA treatment scenario (2016, 32 600 treated; 2017, 21 370 treated; 2018 17 100 treated; 2019 and beyond, 13 680 treated each year) would avert 40 420 new HCV infections, 13 260 liver-related deaths (15 320 in viraemic; -2060 in cured) and 10 730 HCC cases, equating to a 53%, 63% and 75% reduction, respectively, compared to the IFN-based scenario. The model also estimated that Australia will meet the WHO targets of incidence and treatment by 2028. Time to a 65% reduction in liver-related mortality varied considerably between HCV viraemic only cases (2026) and all cases (2047). Based on a feasible DAA treatment scenario incorporating declining uptake, Australia should meet key WHO HCV elimination targets in 10 to15 years. The pre-DAA escalation in those with advanced liver disease makes the achievement of the liver-related mortality target difficult.

RESUMO

OBJECTIVES: Strong collaboration between researchers, policy makers and practitioners supports the use of research evidence in policy and practice. Strategies for increasing the use of evidence in policy development and implementation include creating more opportunities for closer collaboration between researchers and policy makers, ensuring research syntheses are more accessible to policy makers, and increasing workforce capacity to utilise evidence. Type of program or service: The BBV & STI Research, Intervention and Strategic Evaluation Program, 2014-2019 (BRISE) is a coherent and integrated program that delivers policy-relevant research, strategic advice, capacity building and communications to support the response to blood-borne viruses (BBV) and sexually transmissible infections (STI) in New South Wales (NSW), Australia. BRISE has five key objectives: generate high-quality research; maximise the use of research; build research capacity; communication and marketing; and governance and management. RESULTS: BRISE facilitates the coproduction of research where researchers and policy makers are meaningfully involved in all stages of research priority setting and codesign from development to application, building an understanding of the way evidence is generated to allow for greater integration between research and use of evidence. LESSONS LEARNT: Bringing multiple research projects together under a single contract and budget provided the NSW Ministry of Health (the Ministry) with cost efficiencies and streamlined contract management and project reporting. A flexible work plan allowed for a mix of longer-term (up to 5-year) projects and shorter projects that were responsive to emerging policy-relevant research priorities. The Ministry became involved in the production of collaborative research as a research partner, rather than solely a research 'funder'. The joint management of research projects involving a policy officer from the Ministry provided opportunities for individuals to build on their research capabilities and literacy. Collaborative priority setting and project work, and increased research literacy, improved the likelihood that research generated would then be used in policy and practice.
