Diagnostic Accuracy of Urine Flow Cytometry in Excluding Bacteruria

NCT04686292 | Completed

• 1 other identifier: SHS-ED-12b-2020
• Study Type: observational
• Target: 966
• Locations: 1 country
• Sites: 1

Brief Summary

A more rapid test for bacteriuria is desired. This will exclude the patients not having bacteriuria, which will contribute to a more rapid and accurate diagnosis of infectious diseases. The aim of the study is to investigate the diagnostic accuracy of point-of-care urine flow cytometry on diagnosing and excluding bacteriuria

Conditions

Acute Infection

Keywords

Emergency department; Acute infections; bacteruria; urinary tract infections; diagnosis

Outcome Measures

Primary Outcomes (1)

• Bacteriuria

  The urine culture analysis combined with microbiologist assessment will be used as reference standard for bacteriuria. Diagnostic accuracy will be conducted, and Youden index analysis will be used to estimate the best cut-off

  urine collected within 4 hours of arrival to emergency department and analysed within one week

Secondary Outcomes (1)

• Verified infectious diagnosis by expert panel

  2 months after discharge

Other Outcomes (8)

• Intensive care unit treatment

  within 60 days from admission to emergency department

• Length of stay

  within 60 days from admission to emergency department

• The number of participants who died within 30 days

  within 30 days from arrival day

Study Arms (1)

Suspected infection

All patients admitted to the emergency department with suspected infections assessed by the receiving physician

Diagnostic Test: urine flow cytometry

Interventions

urine flow cytometry DIAGNOSTIC_TEST

Diagnostic test of urine flow cytometry. A urine sample will be collected according to routine procedure by a study assistant. The sample will be divided into two aliquots; half for routine urine culturing, and half for Point-of-care Urine Flow cytometry (POC-UFC) analysis (UF-5000, Sysmex, Kobe, Japan). The analysis will be performed according to manufacturer's instruction and conducted by laboratory staff. Laboratory staff will be blinded to the participants diagnosis and outcome. The results of the POC-UFC analysis will not be visible to the treating physician.

Suspected infection

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Acutely admitted patients with suspected infections from three emergency departments (EDs) in the Region of Southern Denmark (Hospital Sønderjylland, Hospital Lillebælt, Odense University Hospital)

You may qualify if:

• Suspicion of acute infections assessed by the receiving physician at the emergency department

You may not qualify if:

• If the attending physician considers that participation will delay a life-saving treatment or patient needs direct transfer to the intensive care unit.
• Admission within the last 14 days
• Verified COVID-19 disease within 14 days before admission
• Pregnant women
• Severe immunodeficiencies: Primary immunodeficiencies and secondary immunodeficiencies (HIV positive CD4 \<200, Patients receiving immunosuppressive treatment (ATC L04A), Corticosteroid treatment (\>20 mg/day prednisone or equivalent for \>14 days within the last 30 days), Chemotherapy within 30 days)
