We aimed to assess the prevalence of newly diagnosed HIV infection among the people referring to the Emergency Department (ED), with the goal to increase new diagnoses by an opt-out, risk-based screening approach. Method: This is an interim analysis of a single center, longitudinal, interventional study including participants referring to the Emergency Department of Policlinico Umberto I (University Hospital of Sapienza University in Rome). Demographic and clinical data were collected from October 2022 to June 2023 and were used for a descriptive statistical analysis. Results: Over the study period considered, a total of 704 participants were enrolled into the study and accepted to undergo rapid HIV testing. Demographics, reasons to refer to the ED and risk factors for HIV acquisition are shown in Table 1. Out of the 704 rapid HIV tests performed, 5 provided a positive result, which was confirmed in 4 cases, allowing a new diagnosis of HIV infection among 4 participants; two were presenting with pneumonia and no other known risk factor for HIV, one case with rash and fever, and another one with scabies. The fifth participant was offered the test because of fever at the access to the ED; after a positive result at the rapid screening test for HIV, the downstream tests resulted negative, thus it was considered a false positive. Conclusions: Our results alarmingly showed a high prevalence of new diagnosis of HIV infection among people referring to the ED. This highlights the added value of the use of rapid HIV testing strategies within the context of the ED. Moreover, screening approaches aiming to address directly those people at higher risk for HIV infection. General conditions 1.
