The classification accuracy of injury location and injury type for all members pooled together is 79.7% agreement for assessment 1 and 78.8% agreement for assessment 2. The classification was subsequently stratified by years of surgical experience and surgical subspecialty. Values are given as number of cases (%) unless otherwise indicated. Not all surgeons completed every question, so denominators vary. Boldface type indicates statistical significance (p < 0.05).
