Does Point-of-care Ultrasound Use Impact Resuscitation Length, Rates of Intervention, and Clinical Outcomes During Cardiac Arrest? A Study from the Sonography in Hypotension and Cardiac Arrest in the Emergency Department (SHoC-ED) Investigators.

Introduction This third study in the Sonography in Hypotension and Cardiac Arrest in the Emergency Department (SHoC-ED) series examined potential relationships between point-of-care ultrasound (PoCUS) use and the length of resuscitation, the frequency of interventions, and clinical outcomes during cardiac arrest. Methods A health records review was completed for adult patients (>19 years, without a do not resuscitate (DNR) order) who presented to a tertiary emergency department in cardiac arrest between 2010 and 2014. Patients were grouped based on PoCUS use and findings for cardiac activity.

To Choose or Not To Choose: Evaluating the Effect of a Choosing Wisely Knowledge Translation Initiative for Imaging in Low Back Pain by Emergency Physicians.

Introduction: We aimed to quantify the baseline familiarity of emergency medicine (EM) physicians with the Choosing Wisely Canada (CWC)-EM recommendations. We then assessed whether a structured knowledge translation (KT) initiative affected awareness, knowledge, and practice patterns for imaging in low back pain.

Methods: We completed a two-center, before and after practice evaluation study.

Do Electrocardiogram Rhythm Findings Predict Cardiac Activity During a Cardiac Arrest? A Study from the Sonography in Cardiac Arrest and Hypotension in the Emergency Department (SHoC-ED) Investigators.

Introduction Electrocardiographic (ECG) rhythms are used during advanced cardiac life support (ACLS) to guide resuscitation management. Survival to hospital discharge has been reported to be better for patients with pulseless electrical activity (PEA) than asystole in out-of-hospital arrests. Despite this, treatment for these two (non-shockable) rhythms is combined in ACLS guidelines.

Do Guidelines Influence Emergency Department Staff Behaviours and Improve Patient Outcomes? Evaluation of a Multifaceted Intervention for the Implementation of Local Acute Exacerbations of Chronic Obstructive Pulmonary Disease Guidelines.

Introduction Published national guidelines on chronic obstructive pulmonary disease (COPD) highlight the importance of oxygen therapy, bronchodilators, corticosteroids, and appropriate antibiotics during acute exacerbations of COPD (AECOPD). We wished to assess how the implementation of local COPD guidelines affects emergency department (ED) staff awareness, knowledge, the use of such guidelines, and patient outcomes, including treatment failure and rates of return to the ED. Methods This study was conducted at a tertiary hospital ED.

Can You Teach Yourself Point-of-care Ultrasound to a Level of Clinical Competency? Evaluation of a Self-directed Simulation-based Training Program.

Introduction Self-directed learning in medical professions is established as an effective method of training in certain modalities. Furthermore, simulation technology is becoming widely used and accepted as a valid method of training for various medical skills, with ultrasound being one of the best studied. The use of point-of-care ultrasound (PoCUS) in the practice of emergency medicine is well established, and PoCUS is a core competency of the Royal College of Physicians and Surgeons of Canada emergency medicine standards.

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.

Study Objective: 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.

A comparison of work stressors in higher and lower resourced emergency medicine health settings.

Objectives: The study compares experiences of workplace stressors for emergency medicine trainees and specialists in settings where the specialty is relatively well resourced and established (Canada), and where it is newer and less well resourced (South Africa, (SA)).

Methods: We conducted an online cross-sectional survey of emergency medicine trainees and physicians in both countries for six domains (demands, role, support, change, control, and relationships) using the validated Management Standards Indicator Tool (MSIT, Health, and Safety Executive, United Kingdom).

Results: 74 SA and 430 Canadian respondents were included in our analysis.

Does Frequency of ST-Segment Elevation Myocardial Infarction Presentation Impact Quality of Care?

Objectives The volume of ST-Segment Elevation Myocardial Infarctions (STEMIs) presenting to an emergency department (ED) has been shown to affect treatment quality measures and patient outcomes. Almost half of ST-elevation-myocardial-infarction (STEMI) patients in New Brunswick (NB) present directly to community hospitals. This study seeks to determine if the quality of care received by STEMI patients presenting to EDs in NB is related to the volume of STEMI presentations at that center.

My patient has abdominal and flank pain: Identifying renal causes.

Acute flank and abdominal pain are common presenting complaints in the emergency department. With increasing access to point-of-care ultrasound (PoCUS), emergency physicians have an added tool to help identify renal problems as a cause of a patient's pain. PoCUS for hydronephrosis has a sensitivity of 72-83.

Weather factors associated with paediatric croup presentations to an Australian emergency department.

We examined if croup presentations to the emergency department (ED) were associated with weather changes in a warm temperate climate. We collected data on all 729 cases with an ED discharge or admission diagnosis of croup over a 798 day time period. We obtained detailed climatic records from the New South Wales Meteorological Office for the same time period.

A method for reviewing the accuracy and reliability of a five-level triage process (canadian triage and acuity scale) in a community emergency department setting: building the crowding measurement infrastructure.

Objectives. Triage data are widely used to evaluate patient flow, disease severity, and emergency department (ED) workload, factors used in ED crowding evaluation and management. We defined an indicator-based methodology that can be easily used to review the accuracy of Canadian Triage and Acuity Scale (CTAS) performance.

An evaluation of the use of whole-body computed tomography in trauma patients at a United Kingdom trauma centre.

We sought to identify the impact of whole-body computed tomography (WBCT) on working and suspected diagnoses in Emergency Department (ED) trauma patients and to determine the rate of WBCT scans with no detectable traumatic injuries. We performed a retrospective database analysis of all trauma patients who underwent WBCT in 2009, comparing pretest suspicion of specific injury to WBCT findings, looking for the rates of unexpected findings and the absence of traumatic injury in WBCT studies. Our results showed that of the 179 patients who underwent WBCT, no traumatic injury reported in 17 patients while 162 patients demonstrated pathology (47 confirming previously suspected or diagnosed injury and 115 with previously unexpected injury).
