In this issue of JAMA Surgery, Lale and coauthors1 are to be congratulated on their attempts to quantify and categorize the extent and outcomes of undertriage of patients with firearm-related injuries in Chicago. The study's strengths include the size of the databases and the use of geographic information systems to map the most affected areas of the city. The authors conclude that undertriage is a problem, given that nearly one-third of patients were treated at facilities that were not designated as trauma centers and that many patients met national anatomic triage criteria.
