Objectives: Between 2013 and 2014, a third of Australian adults reported using the internet to investigate medical symptoms before consulting a medical practitioner. However, there is limited evidence regarding internet health information seeking behaviour (HISB) in sexual health. This study aims to determine the frequency, predictors and accuracy of internet HISB for sexual health self-diagnosis.Methods: A cross-sectional paper-based survey, available in English, Chinese and Thai, was conducted during April to August 2019 at the Sydney Sexual Health Centre (SSHC). Symptomatic patients were recruited to answer an 18-item survey on their HISB, self-assessed diagnosis, anxiety and health literacy. Survey responses were correlated with SSHC electronic medical record data including participant demographics and clinician diagnosis. Data analyses were performed using Stata V.14.Results: The majority of participants searched the internet (355; 79.1%) before attending clinic, and of these only 16.9% made a correct self-diagnosis. Multivariate analyses demonstrated that relative to Australian-born participants, people born in Asia were twice as likely to undertake internet HISB (adjusted OR (AOR) 2.41, 95% CI 1.25 to 4.64, p<0.01), and those born in Latin America were more likely to self-diagnose correctly (AOR 3.35, 95% CI 1.20 to 9.37, p<0.01). On average, participants who searched the internet scored higher relative to those who did not search, on measures of feeling generally tense (2.26, 95% CI 2.16 to 2.7 and 1.86, 95% CI 1.67 to 2.05, p<0.001), upset (1.96, 95% CI 1.85 to 2.08 and 1.53, 95% CI 1.35 to 1.72, p<0.001) and worried (2.55, 95% CI 2.44 to 2.65, and 2.16, 95% CI 1.95 to 2.38, p=0.001).Conclusions: This study has filled important gaps in the literature and highlighted the high prevalence of adults engaging in HISB for sexual health information. Of concern are the increased levels of anxiety and low accuracy of self-diagnoses associated with HISB. Strategies to direct patients to reputable and user-friendly health websites that mitigate anxiety and misinterpretation of online health information should be explored. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Background: In Australia, pre-exposure prophylaxis (PrEP) is targeted to individuals at high risk for HIV infection. We describe the HIV risk profile and characteristics of PRELUDE participants, and evaluate the population validity of the sample in representing high-risk gay and bisexual men (GBM) eligible for PrEP. Methods: PRELUDE is an on-going, open-label, single-arm observational study. Participants were identified in clinics and screened for eligibility using a paper-based risk assessment tool which followed the New South Wales (NSW) PrEP guidelines. Selection was validated using an independent online behavioural survey, completed by study participants upon enrolment. Demographic information was analysed using descriptive statistics, and kappa tests were used to determine agreement between reporting of high-risk practices in the risk assessment and behavioural survey. Results: During 2014–15, 471 individuals were targeted for enrolment; 341 were assessed for PrEP eligibility and 313 were enrolled. Of these, 303 (97%) identified as GBM. Overall, 85% of GBM met at least one high-risk criterion; 68% reported receptive intercourse with an HIV-positive or unknown status casual male partner, and 37% reported methamphetamine use in the three months preceding enrolment. The remaining 15% were enrolled based on medium-risk behaviours, or at the clinicians’ discretion. We found an 82% total agreement between self-reported high-risk behaviour and clinicians’ categorisation of GBM as being at high risk for HIV based on PrEP eligibility criteria. Conclusions: Behavioural eligibility criteria used by clinicians successfully identified individuals at high risk for HIV infection. This targeted approach ensures that the greatest public health and HIV prevention benefits can be derived in a setting without universal access to PrEP. [ABSTRACT FROM AUTHOR]

Introduction: The effectiveness of daily pre-exposure prophylaxis (PrEP) is well established. However, there has been increasing interest in non-daily dosing schedules among gay and bisexual men (GBM). This paper explores preferences for PrEP dosing schedules among GBM at baseline in the PRELUDE demonstration project., Materials and Methods: Individuals at high-risk of HIV were enrolled in a free PrEP demonstration project in New South Wales, Australia, between November 2014 and April 2016. At baseline, they completed an online survey containing detailed behavioural, demographic, and attitudinal questions, including their ideal way to take PrEP: daily (one pill taken every day), event-driven (pills taken only around specific risk events), or periodic (daily dosing during periods of increased risk)., Results: Overall, 315 GBM (98% of study sample) provided a preferred PrEP dosing schedule at baseline. One-third of GBM expressed a preference for non-daily PrEP dosing: 20% for event-driven PrEP, and 14% for periodic PrEP. Individuals with a trade/vocational qualification were more likely to prefer periodic to daily PrEP [adjusted odds ratio (aOR) = 4.58, 95% confidence intervals (95% CI): (1.68, 12.49)], compared to individuals whose highest level of education was high school. Having an HIV-positive main regular partner was associated with strong preference for daily, compared to event-driven PrEP [aOR = 0.20, 95% CI: (0.04, 0.87)]. Participants who rated themselves better at taking medications were more likely to prefer daily over periodic PrEP [aOR = 0.39, 95% CI: (0.20, 0.76)]., Discussion: Individuals' preferences for PrEP schedules are associated with demographic and behavioural factors that may impact on their ability to access health services and information about PrEP and patterns of HIV risk. At the time of data collection, there were limited data available about the efficacy of non-daily PrEP schedules, and clinicians only recommended daily PrEP to study participants. Further research investigating how behaviours and PrEP preferences change correspondingly over time is needed., Trial Registration: ClinicalTrials.gov NCT02206555. Registered 28 July 2014.
