Which adults aged 65 and older are at low-risk for cervical spine injuries after low-level falls?

Objectives: The population is aging and falls are a common reason for emergency department visits. Appropriate imaging in this population is important. The objectives of this study were to estimate the prevalence of cervical spine injury and identify factors associated with cervical spine injuries in adults ≥ 65 years after low-level falls.

Effectiveness of pharmacological treatments for severe agitation in real-world emergency settings: protocol of individual-participant-data network meta-analysis.

Background: Severe psychomotor agitation and aggression often require immediate pharmacological intervention, but clear evidence-based recommendations for choosing among the multiple options are lacking. To address this gap, we plan a systematic review and individual-participant-data network meta-analysis to investigate their comparative effectiveness in real-world emergency settings with increased precision.

Methods: We will include randomized controlled trials investigating intramuscular or intravenous pharmacological interventions, as monotherapy or in combination, in adults with severe psychomotor agitation irrespective of the underlying diagnosis and requiring rapid tranquilization in general or psychiatric emergency settings.

Emergency physician gender and head computed tomography orders for older adults who have fallen.

Objective: Physicians vary in their computed tomography (CT) scan usage. It remains unclear how physician gender relates to clinical practice or patient outcomes. The aim of this study was to assess the association between physician gender and decision to order head CT scans for older emergency patients who had fallen.

Derivation of the Falls Decision Rule to exclude intracranial bleeding without head CT in older adults who have fallen.

Background: Ground-level falls are common among older adults and are the most frequent cause of traumatic intracranial bleeding. The aim of this study was to derive a clinical decision rule that safely excludes clinically important intracranial bleeding in older adults who present to the emergency department after a fall, without the need for a computed tomography (CT) scan of the head.

Methods: This prospective cohort study in 11 emergency departments in Canada and the United States enrolled patients aged 65 years or older who presented after falling from standing on level ground, off a chair or toilet seat, or out of bed.

Risk factors associated with 1-week revisit among emergency department patients with alcohol withdrawal.

Background: Approximately one-quarter of emergency department (ED) visits for alcohol withdrawal result in unscheduled 1-week ED return visits, but it is unclear what patient and clinical factors may impact this outcome METHODS: From January 1, 2015, to December 31, 2018, at three urban EDs in Vancouver, Canada, we studied patients who were discharged with a primary or secondary diagnosis of alcohol withdrawal. We performed a structured chart review to ascertain patient characteristics, ED treatments, and the outcome of an ED return within 1 week of discharge. We used univariable and multivariable Bayesian binomial regression to identify characteristics associated with being in the upper quartile of 1-week ED revisits.

What is the risk of returning to the emergency department within 30 days for patients diagnosed with substance-induced psychosis?

Objectives: The primary objective of this study was to measure the risk of return Emergency Department (ED) visits in patients presenting to the ED with a diagnosis of substance-induced psychosis. Secondary objectives included: (1) describing the characteristics of patients returning within 30 days to the ED with substance-induced psychosis, and (2) identifying risk factors associated with such ED return.

Methods: At two urban sites from January 1, 2018 to December 31, 2019, we included consecutive patients presenting to the ED with substance-induced psychosis defined by their ED discharge diagnosis of psychosis and clinical evidence of substance use.

One-year mortality of emergency department patients with substance-induced psychosis.

Objectives: Psychosis is a well established complication of non-prescription drug use. We sought to measure the 1-year mortality of emergency department patients with substance-induced psychosis (SIP).

Methods: This study was a multi-centre, retrospective electronic medical records review of patients presenting to the ED with substance-induced psychosis (SIP).

Exploring how to enhance care and pathways between the emergency department and integrated youth services for young people with mental health and substance use concerns.

Background: Integrated youth services (IYS) provide multidisciplinary care (including mental, physical, and social) prioritizing the needs of young people and their families. Despite a significant rise in emergency department (ED) visits by young Canadians with mental health and substance use (MHSU) concerns over the last decade, there remains a profound disconnect between EDs and MHSU integrated youth services. The first objective of this study was to better understand the assessment, treatment, and referral of young people (ages 12-24 years) presenting to the ED with MHSU concerns.

Social determinants of health and depression in adults presenting to the emergency department: Implications for family medicine.

Objective: To estimate the extent to which social determinants of health (SDH) predict levels of depression in adults presenting to the emergency department (ED) with an acute mental health crisis.

Design: Secondary data analysis.

Setting: St Paul's Hospital, an urban tertiary care hospital in Vancouver, BC.

Rapid Agitation Control With Ketamine in the Emergency Department: A Blinded, Randomized Controlled Trial.

Study Objective: We hypothesized that the use of intramuscular ketamine would result in a clinically relevant shorter time to target sedation.

Methods: We conducted a randomized clinical trial comparing the rapidity of onset, level of sedation, and adverse effect profile of ketamine compared to a combination of midazolam and haloperidol for behavioral control of emergency department patients with severe psychomotor agitation. We included patients with severe psychomotor agitation measured by a Richmond Agitation Score (RASS) ≥+3.

Which older emergency patients are at risk of intracranial bleeding after a fall? A protocol to derive a clinical decision rule for the emergency department.

Introduction: Falling on level ground is now the most common cause of traumatic intracranial bleeding worldwide. Older adults frequently present to the emergency department (ED) after falling. It can be challenging for clinicians to determine who requires brain imaging to rule out traumatic intracranial bleeding, and often head injury decision rules do not apply to older adults who fall.

Physician choices in pulmonary embolism testing.

Background: Evidence-based guidelines advise excluding pulmonary embolism (PE) diagnosis using d-dimer in patients with a lower probability of PE. Emergency physicians frequently order computed tomography (CT) pulmonary angiography without d-dimer testing or when d-dimer is negative, which exposes patients to more risk than benefit. Our objective was to develop a conceptual framework explaining emergency physicians' test choices for PE.

Bystanders are less willing to resuscitate out-of-hospital cardiac arrest victims during the COVID-19 pandemic.

Aim: The COVID-19 pandemic may influence the willingness of bystanders to engage in resuscitation for out-of-hospital cardiac arrest. We sought to determine if and how the pandemic has changed willingness to intervene, and the impact of personal protective equipment (PPE).

Methods: We distributed a 12-item survey to the general public through social media channels from June 4 to 23, 2020.

Lorazepam Versus Diazepam in the Management of Emergency Department Patients With Alcohol Withdrawal.

Study Objective: Alcohol withdrawal is a common emergency department (ED) presentation. Although benzodiazepines reduce symptoms of withdrawal, there is little ED-based evidence to assist clinicians in selecting appropriate pharmacotherapy. We compare lorazepam with diazepam for the management of alcohol withdrawal to assess 1-week ED and hospital-related outcomes.

Survival After Intravenous Versus Intraosseous Amiodarone, Lidocaine, or Placebo in Out-of-Hospital Shock-Refractory Cardiac Arrest.

Background: Antiarrhythmic drugs have not proven to significantly improve overall survival after out-of-hospital cardiac arrest from shock-refractory ventricular fibrillation/pulseless ventricular tachycardia. How this might be influenced by the route of drug administration is not known.

Methods: In this prespecified analysis of a randomized, placebo-controlled clinical trial, we compared the differences in survival to hospital discharge in adults with shock-refractory ventricular fibrillation/pulseless ventricular tachycardia out-of-hospital cardiac arrest who were randomly assigned by emergency medical services personnel to an antiarrhythmic drug versus placebo in the ALPS trial (Resuscitation Outcomes Consortium Amiodarone, Lidocaine or Placebo Study), when stratified by the intravenous versus intraosseous route of administration.
