A shortcut review was carried out to establish whether serum procalcitonin levels can be used to identify serious bacterial infection in ED patients with undifferentiated SIRS. 14 papers presented the best evidence to answer the clinical question. The review concludes that raised procalcitonin levels are associated with bacteraemia; however, there are no clinical management studies addressing this question in ED patients with SIRS.
