Procalcitonin Biomarker Improves Antibiotic Stewardship

Procalcitonin Biomarker Improves Antibiotic Stewardship

Antimicrobial resistance is a global health threat. Antimicrobial stewardship programmes may be defined as “a coherent set of actions which promote using antimicrobials responsibly.” One such potential action is to implement procalcitonin (PCT) as a clinical decision aid to improve antibiotic use. PCT is a biomarker that increases in response to bacterial rather than viral stimuli. Moreover, it rises rapidly after inflammatory stimuli (4–6h) and has a short half-life of 24h.
