In the Original Investigation titled “NEXUS Chest: Validation of a Decision Instrument for Selective Chest Imaging in Blunt Trauma” published online August 7, 2013, and published in the October issue of JAMA Surgery (2013;148[10]:940-946. doi:10.1001/jamasurg/2013.2757), an incorrect affiliation was assigned to Mr Mulkerin. It should have read “Department of Emergency Medicine, University of California, Irvine (Langdorf and Mulkerin).” This article was corrected online.
