Effect of a Point-of-Care Ultrasound-Driven vs Standard Diagnostic Pathway on 24-Hour Hospital Stay in Emergency Department Patients with Dyspnea-Protocol for A Randomized Controlled Trial.

Purpose: Point-of-care ultrasound (POCUS) helps emergency department (ED) physicians make prompt and appropriate decisions, but the optimal diagnostic integration and potential clinical benefits remain unclear. We describe the protocol and statistical analysis plan for a randomized controlled trial. The objective is to determine the effect of a POCUS-driven diagnostic pathway in adult dyspneic ED patients on the proportion of patients having a hospital stay of less than 24 hours when compared to the standard diagnostic pathway.

Can clinicians identify community-acquired pneumonia on ultralow-dose CT? A diagnostic accuracy study.

Background: Without increasing radiation exposure, ultralow-dose computed tomography (CT) of the chest provides improved diagnostic accuracy of radiological pneumonia diagnosis compared to a chest radiograph. Yet, radiologist resources to rapidly report the chest CTs are limited. This study aimed to assess the diagnostic accuracy of emergency clinicians' assessments of chest ultralow-dose CTs for community-acquired pneumonia using a radiologist's assessments as reference standard.

Utility of ultrasound in the diagnostic work-up of suspected pulmonary embolism: an open-label multicentre randomized controlled trial (the PRIME study).

Background: Prevalence of pulmonary embolism (PE) in patients referred to diagnostic imaging is decreasing, indicating a need for improving patient selection. The aim of this study was to assess reduction in referral to diagnostic imaging by integrating a bespoke ultrasound protocol and describe associated failure rate and adverse events in patients with suspected PE.

Methods: In a randomized open-label multicentre trial spanning June 18, 2021, through Feb 1, 2023, adult patients with suspected PE and 1) a Wells score of 0-6 and elevated age-adjusted D-dimer or 2) Wells score >6 were randomly assigned 1:1 to direct diagnostic imaging (controls) or focused lung, cardiac, and deep venous ultrasound by unblinded investigators.

Diagnostic Performance of Plasma SP-D, KL-6, and CC16 in Acutely Hospitalised Patients Suspected of Having Community-Acquired Pneumonia-A Diagnostic Accuracy Study.

Community-acquired pneumonia is a common cause of acute hospitalisation. Identifying patients with community-acquired pneumonia among patients suspected of having the disease can be a challenge, which causes unnecessary antibiotic treatment. We investigated whether the circulatory pulmonary injury markers surfactant protein D (SP-D), Krebs von den Lungen-6 (KL-6), and Club cell protein 16 (CC16) could help identify patients with community-acquired pneumonia upon acute admission.

Education in Focused Assessment With Sonography for Trauma Using Immersive Virtual Reality: A Prospective, Interventional Cohort Study and Non-inferiority Analysis With a Historical Control.

Objective: Focused assessment with sonography for trauma (FAST) is a valuable ultrasound procedure in emergency settings, and there is a need for evidence-based education in FAST to ensure competencies. Immersive virtual reality (IVR) is a progressive training modality gaining traction in the field of ultrasound training. IVR holds several economic and practical advantages to the common instructor-led FAST courses using screen-based simulation (SBS).

Management of medical emergency patients in Danish emergency departments.

Introduction: In many emergency departments (ED), specialised teams are activated to take care of medical emergency patients (MEP). The aim of this study was to describe the organisation of the management of adult MEPs in Danish EDs. The study examined trigger team activation criteria, training and composition of trigger teams.

Impact of serial cardiopulmonary point-of-care ultrasound exams in patients with acute dyspnoea: a randomised, controlled trial.

Background: Serial point-of-care ultrasound (PoCUS) can potentially improve acute patient care through treatment adjusted to the dynamic ultrasound findings. The objective was to investigate if treatment guided by monitoring patients with acute dyspnoea with serial cardiopulmonary PoCUS and usual care could reduce the severity of dyspnoea compared with usual care alone.

Methods: This was a randomised, controlled, blinded-outcome trial conducted in three EDs in Denmark between 9 October 2019 and 26 May 2021.

Focused cardiac ultrasound (FoCUS) is a point-of-care cardiac examination performed and interpreted by the emergency physician in the clinical context. This review summarises the current knowledge of FoCUS. The objective is to answer four predefined clinical questions: Are there any signs of pericardial effusion? Are there any signs of right ventricular dilatation? Are there any signs of reduced or hyperdynamic left ventricular function? Are there any signs of abnormal inferior vena cava? FoCUS is not a replacement for echocardiography but a useful tool in detecting cardiopulmonary pathology and haemodynamic abnormalities in the emergency setting.

Focused lung ultrasound to predict respiratory failure in patients with symptoms of COVID-19: a multicentre prospective cohort study.

Background: In this study we aimed to assess if a focused lung ultrasound examination predicts the need for mechanical ventilation, admission to an intensive care unit, high-flow oxygen treatment, death from COVID-19 within 30 days and 30-day all-cause mortality in patients with clinical suspicion of COVID-19 or PCR-verified SARS-CoV-2 infection.

Methods: A multicentre prospective cohort trial was performed. Film clips from focused lung ultrasound examinations were recorded and rated by blinded observers using different scoring systems.
