Randomized Controlled Trial Multicenter Study
Does Point-of-Care Ultrasonography Improve Clinical Outcomes in Emergency Department Patients With Undifferentiated Hypotension? An International Randomized Controlled Trial From the SHoC-ED Investigators.
Point-of-care ultrasonography protocols are commonly used in the initial management of patients with undifferentiated hypotension in the emergency department (ED). There is little published evidence for any mortality benefit. We compare the effect of a point-of-care ultrasonography protocol versus standard care without point-of-care ultrasonography for survival and clinical outcomes. ⋯ To our knowledge, this is the first randomized controlled trial to compare point-of-care ultrasonography to standard care without point-of-care ultrasonography in undifferentiated hypotensive ED patients. We did not find any benefits for survival, length of stay, rates of CT scanning, inotrope use, or fluid administration. The addition of a point-of-care ultrasonography protocol to standard care may not translate into a survival benefit in this group.

Multicenter Study Observational Study
The association between systolic blood pressure and in-hospital mortality in older emergency department patients who are hospitalised with a suspected infection.
In existing risk stratification and resuscitation guidelines for sepsis, a hypotension threshold of systolic blood pressure (SBP) below 90-100 mmHg is typically used. However, for older patients, the clinical relevance of a SBP in a seemingly 'normal' range (>100 mmHg) is still poorly understood, as they may need higher SBP for adequate tissue perfusion due to arterial stiffening. We therefore investigated the association between SBP and mortality in older emergency department (ED) patients hospitalised with a suspected infection. ⋯ In older ED patients hospitalised with a suspected infection, we found an inverse linear association between SBP and case-mix-adjusted in-hospital mortality. Our data suggest that the commonly used threshold for hypotension is not clinically meaningful for risk stratification of older ED patients with a suspected infection.

Multicenter Study Observational Study
Development of a new clinical decision rule for cervical CT to detect cervical spine injury in patients with head or neck trauma.
Previous cervical spine imaging decision rules have been based on positive findings on plain X-ray and are limited by lack of specificity, age restrictions and complicated algorithms. We previously derived and validated a clinical decision rule (Rule 1) for detecting cervical spine injury (CSI) on CT in a single-centre study. This recommended CT for patients with (1) GCS score <14, (2) GCS 14-15 and posterior cervical tenderness or neurological deficit, (3) age ≥60 years and fall down stairs, or (4) age <60 and injured in a motorcycle collision or fallen from height. This study assessed the accuracy and reliability of this rule and refined the rule. ⋯ Our initial CT decision rule had lower sensitivity than in our initial validation study. A refined decision rule based on GCS, neck tenderness, neurological deficit and mechanism of injury showed excellent sensitivity with a small loss of specificity. Rule 2 will now need validation in an independent cohort.

Multicenter Study Comparative Study Observational Study
Comparing the Effect of Throughput and Output Factors on Emergency Department Crowding: A Retrospective Observational Cohort Study.
This study compares how throughput and output factors affect emergency department (ED) median waiting room time. ⋯ Both throughput and output factors affect how long newly arriving ED patients remain in the waiting room. This suggests that a range of strategies may help to reduce ED wait time, each requiring stronger ED and hospital partnerships.

A Multicenter Program to Implement the Canadian C-Spine Rule by Emergency Department Triage Nurses.
The Canadian C-Spine Rule has been widely applied by emergency physicians to safely reduce use of cervical spine imaging. Our objective is to evaluate the clinical effect and safety of real-time Canadian C-Spine Rule implementation by emergency department (ED) triage nurses to remove cervical spine immobilization. ⋯ We clearly demonstrated that ED triage nurses can successfully implement the Canadian C-Spine Rule, leading to more rapid and comfortable management of patients without any threat to patient safety. Widespread adoption of this approach should improve care and comfort for trauma patients, and could decrease length of stay in our very crowded EDs.
