Patients often present to emergency departments after potential or confirmed exposure to human immunodeficiency virus (HIV) asking for recommendations concerning the initiation of post-exposure prophylaxis (PEP). These presentations may occur after occupational as well as non-occupational exposure. PEP entails taking a triple antiretroviral therapy for 28-30 days. If taken early (ideally within 2 h, but no later than 72 h) and as indicated, HIV infection can be prevented with a high level of probability. Since these presentations occur around the clock, they require basic expertise on the part of the emergency department staff regarding its indication and its side effects as well as standardized procedures in the emergency department to not delay initiation. Patients should present to an infectious disease outpatient clinic or practice specialized in HIV in order to have the indication reviewed by a specialist and, if necessary, adapted to complex cases with the aim of making individual case decisions. This review article aims to summarize core statements of the 2022 German-Austrian guideline on HIV post-exposure prophylaxis and to give emergency department staff necessary knowledge to safely and correctly begin PEP., (© 2024.
