Zusammenfassung:The translation of deep learning (DL) techniques from research to effective clinical implementations has to overcome an important gap between the DL-development setting and the daily clinical practice. The purpose of this work was to carry out a proof-of-concept study of a DL tool for chest x-rays (CXR) at the emergency department (ED) of our health institution, to measure changes in the performance compared to the retrospective test reported in a prior study; and to compare the model with ED physicians, as they are the intended users of this system. We collected all CXR studies performed during April 2020 in the ED of a 650-bed university hospital, obtaining 508 CXRs from 499 patients. No manual selection or enrichment method were applied. We built a reference standard based on the diagnosis of three senior radiologists and used it to compare the DL model with ED physicians. The model showed a sensitivity of 0.853 and specificity of 0.715 for abnormal findings detection, and an area under the ROC curve of 0.784 (95% CI: 0.746–0.822), which is significantly lower than the value of the prior retrospective test. However, it is significantly higher than the 0.598 (95% CI: 0.54–0.62) value obtained by ED physicians (p
