In patients with suspected sepsis admitted to the Intensive Care Unit, presepsin does not accurately predict the risk of in-hospital death, but it can predict a positive microbiological culture.

Adult patients were included in the study if they met SEPSIS-3 criteria at ICU admission.

Demographic and clinical data were collected. The following inflammatory parameters were determined: C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), and presepsin (P-SEP).

Material was collected for microbiological testing depending on the suspected source of infection.

The primary endpoint was patient death before ICU discharge. The secondary endpoint was a positive microbiological test result.
