Influence of Antibiotic Therapy on Mortality of Critical Surgical Illness Caused or Complicated by Infection

Abstract

The use of scheduled monthly antibiotic cycling in the surgical ICU is associated with a high rate of "appropriate" antibiotic therapy, and appears to maintain or improve resistance patterns. Because antibiotic therapy was mostly appropriate for isolates, initial inappropriate therapy could not be identified as a risk factor for mortality. However, in the setting of appropriate antibiotic choice, the prompt initial administration of antibiotics appears to be crucial for survival, but neither site of infection nor specific pathogen are influential.
