Drug: Empirical antimicrobial treatment discontinuation
Empirical antimicrobial treatment discontinuation will occur when the patient is: Afebrile, with resolution of signs, symptoms and test abnormalities secondary to complementary source of infection and with normalization of vital signs for ≥ 72 h.
Other Name: Clinical rules for finalization of antimicrobial therapy |
Active Comparator: Control Arm
Standard empirical antimicrobial treatment discontinuation
|
Drug: Standard empirical antimicrobial treatment discontinuation
The empirical antimicrobial treatment discontinuation will occur when the patient is: The neutrophil count is above 500 million per mm3. Other Name: Laboratory rules for finalization of antimicrobial therapy |
