The Effect of Contrast Rationing on the Development of Acute Kidney Injury During the Global Contrast Shortage.

Background: In April of 2022, the COVID-19 pandemic resulted in a global shortage of intravenous contrast media (ICM), which led our health care system to implement rationing measures.

Study Objectives: We set out to determine if the reduction in ICM use was associated with a change in the incidence of acute kidney injury (AKI).

Methods: We conducted a multicenter retrospective cohort analysis to compare the incidence of AKI in patients who presented before and after ICM rationing.

The Effect of a Simulation-based Intervention on Emergency Medicine Resident Management of Early Pregnancy Loss.

Background: The evaluation of patients with first-trimester vaginal bleeding and concern for early pregnancy loss (EPL) frequently occurs in the emergency department (ED), accounting for approximately 1.6% of all ED visits. Unfortunately, these patients consistently report negative experiences with ED care.

Effect of Intranasal Vasoconstrictors on Blood Pressure: A Randomized, Double-Blind, Placebo-Controlled Trial.

Background: Treatment for epistaxis includes application of intranasal vasoconstrictors. These medications have a precaution against use in patients with hypertension. Given that many patients who present with epistaxis are hypertensive, these warnings are commonly overridden by clinical necessity.

Implementation of an Opioid Detoxification Management Pathway Reduces Emergency Department Length of Stay.

Objectives: With the rise of opioid use in the United States, the increasing demand for treatment for opioid use disorders presents both a challenge and an opportunity to develop new care pathways for emergency department (ED) patients seeking opioid detoxification. We set out to improve the care of patients presenting to our ED seeking opioid detoxification by implementing a standardized management pathway and to measure the effects of this intervention.

Methods: We conducted a before-after study of the effects of an opioid detoxification management pathway on ED length of stay (EDLOS), use of resources (social worker consultation, laboratory tests obtained), and return visits to the same ED within 30 days of discharge.

Access to primary care and computed tomography use in the emergency department.

Background: The decision to obtain a computed tomography CT scan in the emergency department (ED) is complex, including a consideration of the risk posed by the test itself weighed against the importance of obtaining the result. In patients with limited access to primary care follow up the consequences of not making a diagnosis may be greater than for patients with ready access to primary care, impacting diagnostic reasoning. We set out to determine if there is an association between CT utilization in the ED and patient access to primary care.

Point-of-Care Ultrasound Diagnosis of Traumatic Abdominal Wall Hernia.

Traumatic abdominal wall hernias due to blunt abdominal trauma in pediatric patients can pose a diagnostic challenge because of spontaneous hernia reduction. Ultrasonography may be superior to computed tomography for this indication in some cases because of the ability to dynamically and repeatedly assess the area of injury. Herniation can be induced or exaggerated via Valsalva maneuvers, which can facilitate its detection during dynamic assessment.

Predicting Early Rapid Response Team Activation in Patients Admitted From the Emergency Department: The PeRRT Score.

Objectives: Rapid response teams (RRTs) respond to signs of deterioration to avoid morbidity and mortality. Early RRT activation (eRRT) in patients admitted from the emergency department (ED) is associated with significantly increased mortality. Predicting these events may represent an opportunity to identify patients who would benefit from further resuscitation, aid disposition decision-making, or improve communication between ED and inpatient providers.

Vital Signs Predict Rapid-Response Team Activation Within Twelve Hours of Emergency Department Admission.

Introduction: Rapid-response teams (RRTs) are interdisciplinary groups created to rapidly assess and treat patients with unexpected clinical deterioration marked by decline in vital signs. Traditionally emergency department (ED) disposition is partially based on the patients' vital signs (VS) at the time of hospital admission. We aimed to identify which patients will have RRT activation within 12 hours of admission based on their ED VS, and if their outcomes differed.

Impact of an Emergency Department Observation Unit Management Algorithm for Atrial Fibrillation.

Background: Atrial fibrillation (AF) is a common, growing, and costly medical condition. We aimed to evaluate the impact of a management algorithm for symptomatic AF that used an emergency department observation unit on hospital admission rates and patient outcomes.

Methods And Results: This retrospective cohort study compared 563 patients who presented consecutively in the year after implementation of the algorithm, from July 2013 through June 2014 (intervention group), with 627 patients in a historical cohort (preintervention group) who presented consecutively from July 2011 through June 2012.

Validation of a decision rule for selective TSH screening in atrial fibrillation.

Introduction: Atrial fibrillation (AF) is the most common cardiac dysrhythmia. Current guidelines recommend obtaining thyroid-stimulating hormone (TSH) levels in all patients presenting with AF. Our aim was to investigate the utility of TSH levels for emergency department (ED) patients with a final diagnosis of AF while externally validating and potentially refining a clinical decision rule that recommends obtaining TSH levels only in patients with previous stroke, hypertension, or thyroid disease.
