The fast-paced and multifaceted nature of patient care in the emergency department makes our discipline especially prone to errors and adverse events. In recent years, strategies such as formal communication and medical team training have been proposed as potential means to enhance patient safety. In many ways, practice dynamics particular to the emergency department make this setting almost ideal for implementation of these strategies.

Recent literature pertaining to teams and communication in medicine is reviewed. Copyright © 2010 by Lippincott Williams & Wilkins.
