Utility of procalcitonin in a medical intensive care unit in Croatia

Summary Aims To investigate the clinical benefit of routine procalcitonin (PCT) measurement in the medical intensive care unit (ICU) of a tertiary referral hospital. Methods Adult patients with suspected infections were included. White blood cells, C‑reactive protein (CRP), and PCT were measured. Results In this study 129 patients of median age 64 years (interquartile range 39–89 years) were prospectively included. The Acute Physiology And Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores were 21 ± 14 and 7 ± 6, respectively. Intensive care unit (ICU) mortality was 22.5%. Immunocompromised patients constituted 39.5%. A significant correlation was observed between PCT and APACHE II (Spearman’s rho 0.461, p
