UCSF Medical Center Antimicrobial Susceptibility: Adult Inpatients, Incidence-Weighted Gram-Negative Coverage By Drug 2015

PrintPrintPDFPDF

The table below lists the % of Gram-negative organisms (with at least 10 isolates per year) that tested susceptible to each listed drug or combination.  The values incorporate the frequency with which the various organisms were isolated as well as their sensitivity to the drug; more commonly isolated organisms contribute more to the overall susceptibility results.  Results are based on standard methodology.

Population Ceftriaxone Ertapenem Ceftazidime Cefepime Ciprofloxacin Pip/tazo Meropenem
All adult inpatients 63% (78%)* 81% (99%)* 83% 88% 70% 90% 96%
