Out with the Old and in With the New: Deimplementation in Emergency Medicine.

Much of emergency medicine care and quality standards are rooted in evidence-based guidelines. The Society for Academic Emergency Medicine (SAEM) and the journal Academic Emergency Medicine through publications, conferences, and various initiatives have encouraged the emergency medicine community to create and disseminate evidence-based guidelines. New and updated guidelines must also be implemented into practice. Increasing numbers of publications in this journal and elsewhere are shining light on how the theories and frameworks of implementation science can increase the uptake, reach, and sustainability of evidence-based guidelines in emergency medicine.
