Results

In total, 350 urine samples were analysed. Urinary tract infection (UTI) was diagnosed in 214 patients. ESBL-producing Enterobacterales were isolated from 79 samples. The Cica-beta test showed sensitivity of 79.8% and specificity of 99.3% in patients with Gram-negative bacteriuria. Sensitivity and specificity improved to 90.2% and 100%, respectively, in patients with UTI.

Baseline Characteristics

From July 2019 to November 2019, 1117 consecutive patients on whom urine culture tests were performed were initially Eli- gible. Of these, 767 patients were excluded as 759 did not have Gram-negative bacteriuria and eight had haematuria. Therefore, 350 patients with Gram-negative bacteriuria were included in this study, and the Cica-beta test was performed directly on their urine samples. Among these 350 patients, 214 were diagnosed with UTI.

Participant flow

Patients were eligible if they underwent urine culture tests, and Gram-negative pathogens of at least one per field of view under a 1000x microscope were detected from their urine samples. Patients with haematuria were excluded because it was not possible to evaluate the colour change of the Cica-beta reagent

Adverse events

none

Outcome measures

The primary endpoint was defined as the diagnostic accuracy of the Cica-beta test for ESBL-producing Enterobacterales in patients with bacteriuria or UTI. In this study, patients with UTI were re- garded as those who started antibiotic therapy with a diagnosis of UTI by the attending physicians when urine culture tests were per- formed. Secondary endpoints were set as the turnaround times of the Cica-beta test and standard antibiotic susceptibility tests.

We use beta-lactamase detection reagent to urine samples. We determine whether ESBL producing pathogens are existed in urine samples by color change of a test strip.
