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 ow. 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% condence 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 specic 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.

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 benet 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. 21 Deforest and Thompson 8 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-specic protocols are often unclear. 22 Alternative up-frontinterventions 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 positions funding was discontinued before the evaluation.
