Implementation of HIV-exposures triage strategy in emergency departments to improve nurse-triage for HIV-exposures: A pre- and post-intervention period study

•Quality indicators improvement for HIV-exposures patients in the ED.•A prospective observational 3-years pre- and post-intervention study.•The implementation of rules for HIV exposure improved triage performance.•Simulation training reduced time to access to post exposure prophylaxis (PEP). Health Education in the emergency department (ED) is one of the tasks that the HIV-exposure triage implementation needs to be considered. No triage training has been evaluated. A prospective 3-years pre- and post-intervention study in an urban academic ED was realized. The intervention was a simulation-based training on triage rules for triage nurses. Triage is based on time between HIV-exposure and ED arrival (≤48 h: level 2 (urgent); ≥48 h: level 5 (non-urgent)). A total of 2011 HIV-exposures were included; 15.1 per cent were well triaged in pre-intervention vs. 88 per cent in post-intervention period (P
