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

The diagnostic accuracy of handheld ultrasound (HHUS) devices operated by newly certified operators for pneumonia is unknown. This multicenter study included patients prospectively suspected from February 2021 to 2022 in four emergency departments. index test was a 14-zone focused lung (FLUS) examination, with consolidation air bronchograms as criteria pneumonia. FLUS examinations were performed using HHUS. reference standard computed tomography (CT) and expert diagnosis all medical records....

Background The major obstacle in prescribing an appropriate and targeted antibiotic treatment is insufficient knowledge concerning whether the patient has a bacterial infection, where focus of infection which bacteria are agents infection. A prerequisite for use antibiotics timely access to accurate diagnostics such as point-of-care (POC) testing. study aims evaluate diagnostic tools working methods that support prompt diagnosis hospitalised patients suspected acute We will on most common...

Abstract Background Many factors determine empirical antibiotic treatment of community-acquired pneumonia (CAP). We aimed to describe the CAP patients with an acute hospital visit and if current algorithm provided specific sufficient coverage against Legionella pneumophila, Mycoplasma pneumoniae, Clamydophila pneumoniae (LMC). Methods A descriptive cross-sectional, multicenter study all adults in Region Southern Denmark between January 2016 March 2018 was performed. Using medical records, we...

Objectives This study aimed to describe the clinical characteristics of adults with suspected acute community-acquired pneumonia (CAP) on hospitalisation, evaluate their prediction performance for CAP and compare model initial assessment physician. Design Cross-sectional, multicentre study. Setting The data originated from INfectious DisEases in Emergency Departments were collected prospectively patient interviews medical records. included four Danish emergency departments (EDs) was...

BackgroundUrinary tract infections (UTIs) remain a leading infectious disease cause of admission to the emergency department (ED) and antibiotic prescription. Heterogeneity presentation challenges early diagnostics, improper prescription delayed diagnosis. Prior studies have relied on positive urine cultures for diagnosis, but its performance suffers from false positives negatives. This study aimed identify factors associated with UTIs describe patient characteristics outcomes while not...

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

Background In suspected community-acquired pneumonia (CAP), chest CT is superior to the routinely obtained radiographs (CXR), but administers higher radiation doses. However, ultra-low-dose (ULDCT) has shown promising results. Purpose To compare dose and image quality using standard ULDCT protocols designed for a multicenter study encompassing three scanner models from GE, Canon, Siemens. Material methods Patients with CAP were referred non-contrast (NCCT) ULDCT. Effective Contrast-to-Noise...

Introduktion: Pneumoni er en meget hyppig og alvorlig infektion med høj mortalitet. På trods af studier, der viser manglende sensitivitet, diagnosticeres pneumoni udfra påvist nytilkommet infiltrat på røntgen thorax. Formål: Formålet dette studie var at undersøge hvor mange patienterne diagnostiseret havde et thorax, samt om deres kliniske præsentation adskilte sig fra dem uden nyt infiltrat. Metode: Studiet diagnostisk retrospektiv journalgennemgang patienter diagnosticeret pneumoni, som...

Objective Rapid and accurate infection diagnosis is a prerequisite for appropriate antibiotic prescriptions in an ED. Accurately diagnosing acute infections can be difficult due to nonspecific symptoms limitations of diagnostic testing. The accuracy preliminary diagnoses, established on the initial clinical assessment, depends physician’s skills knowledge. It has been scarcely studied, knowledge how infected patients present at EDs today needed improve it. Based expert reference diagnoses...

Introduction: Quick and reliable assessment of acute patients is required for accurate triage. The temperature gradient between core peripheral could possibly instantly provide information on circulatory status. Methods: Adult medical patients, who did not receive supplementary oxygen, attending two emergency departments, had a thermographic image taken arrival. association 30-day mortality gradients was tested using logistic regression. Results: 726 were studied, median age 64 years 14...
