For nearly 15 years, the US Department of Defense (DoD) Joint Trauma System (JTS) has applied principles of a learning health system, including data collection and analysis, guideline-directed care, and performance improvement initiatives, to advance the well-being of deployed service members.1-3 The study by Le et al4 from the US Army Institute of Surgical Research is another landmark effort demonstrating the value of the JTS and its clinical registry referred to as the DoD Trauma Registry (DoDTR).
