Testing rates improved over the study period from less than one in every 300 patients to, on introduction of POCT, just under half of attendees having an HIV test. The prevalence of hitherto undiagnosed HIV infection in our clinic is almost 1% (with an additional 0.8% of patients declining POCT because of known HIV-positive status). This could be a model for other acute medical settings where HIV prevalence is similar. The high rates of uptake of testing, and the reasons given for declining a test, indicate that offering HIV POCT in such settings is acceptable to patients (and staff). We recognize that our mechanism for measuring acceptability was limited by being contemporaneous, but over this period

we received only one adverse Talazoparib clinical trial Z-IETD-FMK order comment in our anonymous feedback questionnaire from an already HIV-positive man concerned about counselling for new reactives; he was reassured once our process of referral was explained. In addition, other studies in similar settings show that offers of HIV tests are acceptable in community and hospital clinics [14]. Although the higher uptake with POCT than with laboratory testing did not translate into a statistically greater rate

of new diagnoses, our data support previous evidence that POCT, specifically, overcomes additional barriers to testing, by demonstrating a significant increase in acceptance rate compared with a laboratory-based protocol, presumably as a consequence of the perceived reduction in the delay

in receiving a result [8, 9]. Furthermore, rapid HIV POCTs offer an economical advantage in HIV screening programmes [17]. Targeted testing strategies based on dissemination of guidelines and protocols have limited benefit [3, 18]; universal testing strategies, which can be relatively easily provided by a range of healthcare staff, are more effective [19-22]. Reasons for this include the destigmatization of testing, as well as less reliance on busy clinicians (from a range of specialties) to prioritize HIV testing where clinical diagnosis and management are focussed on alternative, more pressing, matters. Selleckchem Venetoclax This is particularly important if the increased international focus on testing is to identify patients with less advanced (and therefore often asymptomatic) disease. Although the numbers were limited, we have demonstrated that POCT screening may identify patients with higher CD4 cell counts, without clinically significant HIV disease. One would certainly expect more patients diagnosed with preserved immune status using a universal testing strategy than a targeted testing strategy based partly on indicator diseases, which are associated with varying degrees of immunosuppression [9]. A universal offer of an HIV test in this setting gives patients who may not attend conventional settings for HIV testing the opportunity to be tested.
