Appropriate Antimicrobial Therapy for Sepsis

  • In previous pearls, we have discussed the importance of early antimicrobial administration for patients with sepsis.
  • In patients with septic shock, current guidelines recommend empiric antimicrobial therapy be initiated within 1 hour.
  • Equally as important as early administration is the selection of appropriate antimicrobial therapy (i.e. choosing an antibiotic that is effective against the presumed or identified pathogen).
  • In one of the most recent studies, investigators found a 5-fold reduction in survival (52% vs. 10.3%) between patients who received appropriate antibiotics compared to those who received antibiotics that were ineffective against the identified pathogen.
  • In fact, choosing the right antibiotic is one of the strongest factors associated with patient outcome in sepsis.
  • When selecting empiric antimicrobial therapy for patients with septic shock consider patient history, co-morbidities, the clinical site of infection, and local resistance data.
