Observational Study
Is there a role for procalcitonin determination in avoiding unnecessary exposure to antibiotics in a non-intensive care setting?
The use of procalcitonin (PCT) as a tool to assist clinicians in using antibiotics in intensive care patients has been postulated. Here we evaluate the efficacy of procalcitonin determination in helping clinicians in the decision to start or discontinue an antibiotic treatment in patients admitted to infectious disease wards. A retrospective observational single centre study was conducted in two infectious disease wards. ⋯ Conversely, in patients with an ongoing antibiotic treatment a statistically significant difference between PCT and CRP AUC in their ability to determine an antibiotic interruption was observed [0.77 (CI 95%: 0.65-0.89) vs 0.59 (CI 95%: 0.45-0.73) (p=0.03)]. PCT determination appeared to be more helpful than CRP in determining discontinuation of an antibiotic treatment in non-intensive care patients. However, PCT should supplement and not supplant a careful clinical evaluation.
