Background And ImportanceThe rates of hidden infection and late diagnosis of HIV still remain high in Western countries. Missed diagnostic opportunities represent the key point in changing the course of the epidemic.ObjectiveTo evaluate the feasibility and results of implementation of a selective strategy to test for HIV in the emergency department (ED) in patients with six pre-defined medical situations: sexually transmitted infections, herpes zoster, community-acquired pneumonia, mononucleosis syndrome, practice of chemsex (CS) or request of post-exposure prophylaxis.DesignThis quasi-experimental longitudinal study evaluated the pre- and post-implementation results of HIV testing in the six aforementioned clinical scenarios.Settings And ParticipantsPatients attended 34 Spanish EDs.Intervention Or ExposureThe intervention was an intensive educational program and pathways to facilitate and track orders and results were designed. We collected and compared pre- and post-implementation ED census and diagnoses, and HIV tests requested and results.Outcome Measures And AnalysisThe main outcome was adherence to the recommendations. Secondary outcomes were to evaluate the effectiveness of the program by the rate of positive test and the new HIV diagnoses. Differences between first and second periods were assessed. The magnitude of changes (absolute and relative) was expressed with the 95% confidence interval (CI).Main ResultsHIV tests increasing from 7080 (0.42% of ED visits) to 13 436 (relative increase of 75%, 95% CI from 70 to 80%). The six conditions were diagnosed in 15 879 and 16 618 patients, and HIV testing was ordered in 3393 (21%) and 7002 (42%) patients (increase: 97%; 95% CI: 90-104%). HIV testing significantly increased for all conditions except for CS. The positive HIV test rates increased from 0.92 to 1.67%. Detection of persons with undiagnosed HIV increased from 65 to 224, which implied a 220% (95% CI: 143-322%) increase of HIV diagnosis among all ED comers and a 71% (95% CI: 30-125%) increase of positive HIV tests.ConclusionImplementation of a strategy to test for HIV in selective clinical situations in the ED is feasible and may lead to a substantial increase in HIV testing and diagnoses.Copyright © 2023 Wolters Kluwer Health, Inc.
