Interpretation of bedside chest X-rays in the ICU: is the radiologist still needed?


Martini, Katharina; Ganter, Christoph; Maggiorini, Marco; Winklehner, Anna; Leupi-Skibinski, Katarzyna E; Frauenfelder, Thomas; Nguyen-Kim, Thi Dan Linh (2015). Interpretation of bedside chest X-rays in the ICU: is the radiologist still needed? Clinical Imaging, 39(6):1018-1023.

Abstract

PURPOSE To compare diagnostic accuracy of intensivists to radiologists in reading bedside chest X-rays. METHODS In a retrospective trial, 33 bedside chest X-rays were evaluated by five radiologists and five intensivists with different experience. Images were evaluated for devices and lung pathologies. Interobserver agreement and diagnostic accuracy were calculated. Computed tomography served as reference standard. RESULTS Seniors had higher diagnostic accuracy than residents (mean-ExpBSenior=1.456; mean-ExpBResident=1.635). Interobserver agreement for installations was more homogenously distributed between radiologists compared to intensivists (ExpBRad=1.204-1.672; ExpBInt=1.005-2.368). Seniors had comparable diagnostic accuracy. CONCLUSION No significant difference in diagnostic performance was seen between seniors of both disciplines, whereas the resident intensivists might still benefit from an interdisciplinary dialogue.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
