Study objective: Emergency department (ED) crowding is a common and complicated problem challenging EDs
worldwide. Nurse-initiated protocols, diagnostics, or treatments implemented by nurses before patients are treated by a
physician or nurse practitioner have been suggested as a potential strategy to improve patient flow.
Methods: This is a computer-randomized, pragmatic, controlled evaluation of 6 nurse-initiated protocols in a busy,
crowded, inner-city ED. The primary outcomes included time to diagnostic test, time to treatment, time to consultation,
or ED length of stay.
Results: Protocols decreased the median time to acetaminophen for patients presenting with pain or fever by 186
minutes (95% confidence interval [CI] 76 to 296 minutes) and the median time to troponin for patients presenting with
suspected ischemic chest pain by 79 minutes (95% CI 21 to 179 minutes). Median ED length of stay was reduced by
224 minutes (95% CI –19 to 467 minutes) by implementing a suspected fractured hip protocol. A vaginal bleeding
during pregnancy protocol reduced median ED length of stay by 232 minutes (95% CI 26 to 438 minutes).
Conclusion: Targeting specific patient groups with carefully written protocols can result in improved time to test or
medication and, in some cases, reduce ED length of stay. A cooperative and collaborative interdisciplinary group is
essential to success. [Ann Emerg Med. 2016;-:1-7.]

INTRODUCTION
Background
Emergency department (ED) crowding has required
broad and creative strategies to ensure timely care
provision.
1
A diverse range of approaches has been
undertaken early in the patients’ stay, such as diagnosis-
specific nurse-initiated protocols that direct evidence-based
care for sepsis,
2
corticosteroids for asthma,
3,4
sickle cell
crisis,
5
chest radiograph in pneumonia,
6
and thrombolysis
for myocardial infarction.
7
The purpose of these protocols
is to make consecutive processes simultaneous and to
improve departmental performance. Alternatively,
protocols can target presenting complaints, such as chest
pain
8
and abdominal pain,
9,10
and direct both diagnostics
and treatments.
Two of the most common nurse-initiated protocols
in the literature are the facilitation of radiographic
examinations of orthopedic injuries
11-14
and analgesia
provision.
9,15-20
The potential benefit of protocols is
reductions in length of stay, especially after the patient is
treated by a physician or nurse practitioner, because
diagnostics are available during initial assessment, allowing
disposition decisionmaking to occur.
10
One such study
determined that the time saving in patient length of stay for
4 different presenting complaint protocols resulted in a
16% reduction in length of stay regardless of protocol
deployed.

Deforest and Thompson

described combining
nurse-initiated protocols with clinical scoring systems to
create advanced nursing directives to have the best available
evidence guide care. Unfortunately, the legality and
acceptance of complaint-specific protocols are often
unclear.
22
Alternative “up-front” interventions include
geographically anchoring nurse practitioners
23
or
physicians
24
at triage to initiate care. The department being
evaluated once had a triage physician, but the position’s
funding was discontinued before the evaluation. Triage
nurses in a 2012 study demonstrated a 76% sensitivity and
