Delayed Recognition of a Positive Blood Culture

The Case


A 58-year-old woman with metastatic breast cancer recently treated with immunosuppressive therapy presented to the hospital for evaluation of diarrhea. As part of the infectious workup performed in the emergency department (ED), blood cultures and stool studies were sent to the laboratory. The following morning, her stool test returned positive for Clostridium difficile (C. difficile), a potent bacteria that can cause serious infections, especially in immunocompromised hosts. At that time, one out of the two blood cultures drawn in the ED was positive for gram-positive rods, but the speciation (type of bacteria) and sensitivity profile (which suggests which antibiotics are best to use) were not yet available. The medical team ordered appropriate antibiotic treatment for C. difficile but did not initiate treatment for the preliminarily positive blood culture. VER CASO COMPLETO AQUI
