Clinical Consequences and Cost of Limiting Use of Vancomycin for Perioperative Prophylaxis: Example of Coronary Artery Bypass Surgery
Figure 2

Figure 2. . Three-way sensitivity analysis of the incidence of surgical site infection (SSI) caused by methicillin-resistant Staphylococcus aureus (MRSA); methicillin-resistant coagulase-negative staphylococci; or cefazolin-susceptible gram-negative bacteria. The lines show the incidence of infection caused by methicillin-resistant Staphylococcus aureus necessary for routine cefazolin prophylaxis to be more cost-effective than routine vancomycin (0.09%, 0.6%, 1.2%, and 1.8%). For a particular line, points to the lower right indicate that routine vancomycin is more cost-effective; points to the upper left indicate that routine cefazolin is more cost-effective. The dotted line represents the example cited in text. SSI = surgical site infection; MRSA = methicillin-resistant Staphylococcus aureus; CNS = coagulase-negative staphylococci; GNB: gram-negative bacteria.
