As a former Emergency Department Nurse, I find it fascinating how the author chose to do the concept analysis on this topic.  According to the author, when patients are forced to stay for extended lengths of time in the emergency department, this leads to poor patient outcomes, overcrowding, and an overall inefficient organization. (Andersson et al., 2020) I recall when a febrile child was left in the Emergency Department for a long time.  The child became so agitated their respiratory status worsened.  The authors aim to clarify the meaning of long EDLOS and identify the root causes of an emergency department length of stay of more than six hours.  (Andersson et al., 2020)
