SECONDARY outcome
Timeframe: 6-20 hours post-operativelyPopulation: 440 participants who were administered vancomycin provided serum samples for analysis. The remaining participants were discharged on the same day as their operation and thus were not available to provide serum samples. Serum samples were not collected from participants who received standard of care.
Vancomycin levels in serum will be tested after surgery, any additional fluid collections, but if and only if clinically indicated. A serum vancomycin level of \>3.0 mg/dl is considered positive.

SECONDARY outcome
Timeframe: 90 days postoperativelyPopulation: Swabs were collected only from participants who received Vancomycin.
Microbial swabs will be obtained by the clinical coordinator preoperatively, post-operatively, at 10-14 days and at 90 days. Staph aureus isolates from mannitol growth will be tested for vancomycin resistance.
