Weighing the gold standard: The breadth of emergency medicine core content covered by textbooks

Textbooks are often considered the criterion standard in medical education, but there is a growing preference for free open-access medical education (FOAM) content among learners. Despite FOAM's appeal, these resources often fall short in covering core content as comprehensively as the American Board of Emergency Medicine's 2019 Model of the Clinical Practice of Emergency Medicine (MCPEM), thereby sustaining the recommendation for textbook use. However, textbooks have limitations, such as how quickly content can become outdated. Notably, there is no evaluation of the comprehensiveness of emergency medicine (EM) textbooks in the literature.
