To overcome this, we conducted a survey of isolated chest trauma using data from the Japan Trauma Data Bank (JTDB).<h4>Methods</h4>Between January 2004 and May 2019, a total of 361,706 trauma cases were recorded in the JTDB. From this cohort, 9,475 patients (2.6%) presenting with isolated chest trauma were identified. These patients were categorized into three cohorts based on the year of registration (2004-2008: n=981; 2009-2013: n=3,338; 2014-2019: n=5,156), and temporal trends in clinical characteristics were evaluated.
