Clinical characteristics and diagnostic accuracy of preliminary diagnoses in adults with infections in Danish emergency departments: a multicentre combined cross-sectional and diagnostic study.

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 and limitations of diagnostic testing. The accuracy of preliminary diagnoses, established on the initial clinical assessment, depends on a physician's skills and knowledge.

Clinical characteristics, factors associated with urinary tract infection and outcome in acutely admitted patients with infection; an exploratory cross-sectional cohort study.

Background: Urinary tract infections (UTIs) remain a leading infectious disease cause of admission to the emergency department (ED) and antibiotic prescription. Heterogeneity of disease presentation challenges early diagnostics, leading to improper antibiotic prescription and delayed diagnosis. Prior studies have relied on positive urine cultures for diagnosis, but its performance suffers from false positives and false negatives.

Community-acquired pneumonia: use of clinical characteristics of acutely admitted patients for the development of a diagnostic model - a cross-sectional multicentre study.

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 the performance of the model to the initial assessment of the physician.

Design: Cross-sectional, multicentre study.

Setting: The data originated from the INfectious DisEases in Emergency Departments study and were collected prospectively from patient interviews and medical records.

Association Between Vegetation Size and Outcome in the Partial Oral Antibiotic Endocarditis Treatment Trial.

Step-down oral antibiotic therapy is associated with a non-inferior long-term outcome compared with continued intravenous antibiotic therapy in the treatment of left-sided infective endocarditis. We aimed to analyze whether step-down oral therapy compared with continued intravenous antibiotic therapy is also associated with a non-inferior outcome in patients with large vegetations (vegetation length ≥ 10 mm) or among patients who underwent surgery before step-down oral therapy. We included patients without presence of aortic root abscess at diagnosis from the POET (Partial Oral Antibiotic Endocarditis Treatment) study.
