To investigate the prognostic role of procalcitonin (PCT) assessment and blood culture (BC) acquisition in the emergency department (ED) in patients with urinary tract infection (UTI) or urosepsis. We enrolled patients admitted for UTI to our ED over a 10-year period. Mortality and in hospital length of stay (LOS) were compared between patients with UTI or urosepsis who had sampling for PCT levels and BC taken in the ED (ePCT group–eBC group) and those who had not (noePCT group–no-eBC group). 1029 patients were analyzed, 52.7% of which were female. Median age was 77 [65–83]; 139 patients (13.5%) had complicated UTI. Median LOS was 10 [7–17] days. In the ePCT group, LOS was 10 [7–16] days, vs. 10 [7–17] (p = 0.428) in the no-ePCT group. In the eBC group, LOS was 10 [6–16] days vs. 10 [7–17] days (p = 0.369) in the no-eBC group. The overall mortality rate was 6.6%. The mortality rate was not affected by early PCT determination (6% in the ePCT group vs. 6.9% in the no-ePCT group, p = 0.584). Similarly, the mortality rate was not different in the eBC group as compared to the no-eBC group (5.4% vs. 6.9%, p = 0.415). Performance of ePCT or eBC testing made no significant difference in terms of improvement of mortality rates in septic patients (11.4% vs. 7.2%; p = 0.397 and 8.8% vs. 9.8%; p = 0.845, respectively). The prognostic relevance of early evaluation of PCT and BC in the ED of patients with febrile UTI appears limited. In complicated UTI patients, PCT and BC testing may be more appropriate in the context of improving antibiotic stewardship, or as an integral component of PCT-guided standardized protocols.
