Introduction: HIV diagnoses among gay and bisexual men have increased over the past decade in Australia. HIV point‐of‐care testing (POCT) was introduced in Australia in 2011 as a strategy to increase HIV testing by making the testing process more convenient. We surveyed gay and bisexual men undergoing POCT to assess barriers to HIV testing and characteristics associated with not having previously tested for HIV (never testing).Methods: During 2011 and 2012, gay and bisexual men who were undergoing POCT at four Sydney sexual health clinics self‐completed questionnaires assessing testing history and psychological and structural barriers to HIV testing. Bivariate and multivariate logistic regression was used to assess associations between patient characteristics and never testing.Results: Of 1093 participants, 981 (89.9%) reported ever testing for HIV and 110 (10.1%) never testing. At least one barrier to testing was reported by 1046 men (95.7%), with only 47 men (4.3%) not reporting any barrier to testing. The most commonly reported barriers to testing were annoyance at having to return for results (30.2%), not having done anything risky (29.6%), stress in waiting for results (28.4%), being afraid of testing positive (27.5%) and having tested recently (23.2%). Never testing was independently associated with being non‐gay‐identified (adjusted odds ratio [AOR]: 1.9; 95% confidence interval [CI]: 1.1–3.2), being aged less than 25 years (AOR: 2.4; 95% CI: 1.6–3.8), living in a suburb with few gay couples (AOR: 1.9; 95% CI: 1.2–3.0), being afraid of testing HIV‐positive (AOR: 1.6; 95% CI: 1.0–2.4), not knowing where to test (AOR: 3.8; 95% CI: 1.3–11.2) and reporting one or no sexual partners in the last six months (AOR: 2.7; 95% CI: 1.2–6.2).Conclusions: Barriers to HIV testing were commonly reported among the clinic‐based gay and bisexual men in this study. Our findings suggest further health promotion and prevention strategies are needed to address the knowledge, attitudes and behavioural factors associated with never testing.

Objective: To investigate the barriers to HIV testing among Australian gay men. Methods: An online survey was conducted to explore reasons for avoiding and delaying testing for HIV; 519 non-HIV-positive men completed the online survey. Results: Most non-HIV-positive men (92.9%) had been tested for HIV, with 75.4% indicating they had been tested in the previous year. The most common reasons for avoiding or delaying testing were a belief that they had not done anything risky (41.2%) and the need to return for a second clinic visit to receive results (40.3%). Among men who engaged in unprotected anal intercourse with casual partners (UAIC), those who had not been recently tested were more likely to cite the lack of any symptoms as reasons for not having tested (adjusted odds ratio: 2.34; 95% confidence interval: 1.03–5.31; P = 0.041). Conclusions: For men who do not engage in risky sex, the decision not to test is probably reasonable, but those who engage in noncondom-based risk reduction may be at some increased risk and should be encouraged to test relatively often. Changes to Australia’s national HIV testing policy may ameliorate some of the need to return for second clinic visits to receive results, but the policy still requires full implementation, including the introduction of rapid point-of-care HIV testing to Australia. Among men who engage in UAIC, there appears to be a particular need for information about the benefits of early treatment after HIV diagnosis and about the relative likelihood of experiencing HIV seroconversion illness.

Determine HIV Combo (DHC) is the first point of care assay designed to increase sensitivity in early infection by detecting both HIV antibody and antigen. We conducted a large multi-centre evaluation of DHC performance in Sydney sexual health clinics. We compared DHC performance (overall, by test component and in early infection) with conventional laboratory HIV serology (fourth generation screening immunoassay, supplementary HIV antibody, p24 antigen and Western blot tests) when testing gay and bisexual men attending four clinic sites. Early infection was defined as either acute or recent HIV infection acquired within the last six months. Of 3,190 evaluation specimens, 39 were confirmed as HIV-positive (12 with early infection) and 3,133 were HIV-negative by reference testing. DHC sensitivity was 87.2% overall and 94.4% and 0% for the antibody and antigen components, respectively. Sensitivity in early infection was 66.7% (all DHC antibody reactive) and the DHC antigen component detected none of nine HIV p24 antigen positive specimens. Median HIV RNA was higher in false negative than true positive cases (238,025 vs. 37,591 copies/ml; p = 0.022). Specificity overall was 99.4% with the antigen component contributing to 33% of false positives. The DHC antibody component detected two thirds of those with early infection, while the DHC antigen component did not enhance performance during point of care HIV testing in a high risk clinic-based population.
