A diagnostic algorithm for detection of urinary tract infections in hospitalized patients with bacteriuria: The “Triple F” approach supported by Procalcitonin and paired blood and urine cultures
Fig 2
Proposed algorithm for identification and classification of urinary tract infections and asymptomatic bacteriuria in hospitalized ED patients with bacteriuria.
The final diagnosis will be established after the completion of the algorithm. If BC obtained, the final diagnosis might be evident after 72 hours. *PCT at triage/ admission acceptable if duration of symptoms > 6 hours, otherwise repeat for re-evaluation if negative and highly suspected infection. Abbreviations: ABU asymptomatic bacteriuria, BC blood cultures, SUTI urinary tract infection with systemic involvement, PCT Procalcitonin, PUB paired urinary cultures and blood cultures, SSTI skin and soft tissue infection, CLABSI catheter-related bloodstream infection.
