Abstract
Unit-specific antibiograms have developed to guide clinicians to appropriate antibiotic choices for subsets of patients. The additional level of a unit- and respiratory-specific antibiogram for surgical and trauma patients defines key differences in susceptibility information for treating hospital-acquired pneumonia. This was a three-year, retrospective single-center study. A total of 729 positive respiratory specimens from 612 patients were analyzed using Quality Compass Pathfinder(®), the antibiotic-reporting software. Culture and susceptibility reports were compared for the surgical/trauma intensive care unit (S/TICU) and the general hospital (excluding the S/TICU but including the medical ICU [MICU]). Data were filtered to include those genera and organisms with a high association with hospital-acquired pneumonia: Acinetobacter, Citrobacter, Enterobacter, Escherichia coli, Haemophilus, Klebsiella, Neisseria, Pseudomonas, Staphylococcus, Stenotrophomonas, Streptococcus, and Serratia. For gram-negative organisms, susceptibility differences were noted for Acinetobacter and Pseudomonas between the S/TICU and the rest of the hospital. In particular, Acinetobacter was significantly more susceptible to ciprofloxacin (86% vs. 43%; ...Continue Reading
