As a former emergency department Registered Nurse for over seven years, I recall the most significant complaints were our long wait times.  For some patients, the wait time could be substantial.  Since emergency departments aren't on a first-come, first-serve basis, wait times were often unpredictable and lengthy.  Patients are triaged based on their level of acuity.  Long Emergency Department (ED) Length of stay (EDLOS) is associated with poor patient outcomes, which has led to the implementation of time targets designed to keep EDLOS below a specific limit.

Long Emergency Department (ED) Length of stay (EDLOS) is
associated with poor patient outcomes, which has led to the
implementation of time targets designed to keep EDLOS below
a specific limit. (Andersson et al., 2020, p. 2)
The method conducted for the concept analysis on EDLOS was
the Walker and Avant approach. They were able to research a
way of measuring the concept empirically by identifying all
concepts used. (Andersson et al., 2020) Nurses can use the

Authors Aim and Purpose
As a former Emergency Department Nurse, I find it fascinating

2. 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)
Defining Attributes on the Concept Examined
In the emergency department, length of stay (LOS) is a widely
used measurement. Emergency department length of stay
(EDLOS) is defined as the time interval between a patient's
arrival to the ED to the time the patient physically leaves the
ED. The defining attributes discovered that waiting in a
crowded emergency department was just that, waiting. Waiting
was the most acknowledged attribute associated with EDLOS.
(Andersson et al., 2020) If the patients didn't have to wait, they
wouldn't be a problem/complaint and had no time targets.
Another attribute that was described as a cause for EDLOS was,
crowding. This led to cause and effect with long EDLOS and
crowding. (Andersson et al., 2020)
Benefits
The problem was that over-crowding and waiting was
referred to as an inefficient organization. This led to the need
to search for EDLOS to correct the issues with the system and
improve overall patient satisfaction with emergency department
visits. (Andersson et al., 2020) The benefit of this study is
discovering what the root of the cause is for long emergency

3. wait times, therefore improving overall patient outcomes,
avoiding overcrowding, and running an efficient organization.
The benefits of completing a concept analysis for nursing theory
would be to aim at improvements for better patient outcomes.
This is what we are there for, after all. As nurses, we are on the
front lines of our departments, and we have an opportunity to
improve our systems, our organizations, our team, but most
importantly, our patients. When we can all benefit as a team,
our profession benefits, and our patients benefit greatly.
