AbstractThe purpose of this study was to examine the hypothesis that an algorithm based on serial measurements of procalcitonin (PCT) allows reduction in the duration of antibiotic therapy compared with empirical rules, and does not result in more adverse outcomes in burn patients with infectious complications. All burn patients requiring antibiotic therapy based on confirmed or highly suspected bacterial infections were eligible. Patients were assigned to either a procalcitonin-guided (study group) or a standard (control group) antibiotic regimen. The following variables were analyzed and compared in both groups: duration of antibiotic treatment, mortality rate, percentage of patients with relapse or superinfection, maximum SOFA score (days 1-28), length of ICU and hospital stay. A total of 46 Burn ICU patients receiving antibiotic therapy were enrolled in this study. In 24 patients antibiotic therapy was guided by daily procalcitonin and clinical assessment. PCT guidance resulted in a smaller antibiotic exposure (10.1±4 vs. 15.3±8 days, p=0.034) without negative effects on clinical outcome characteristics such as mortality rate, percentage of patients with relapse or superinfection, maximum SOFA score, length of ICU and hospital stay. The findings thus show that use of a procalcitonin-guided algorithm for antibiotic therapy in the burn intensive care unit may contribute to the reduction of antibiotic exposure without compromising clinical outcome parameters.
