RESUMEN
We report a higher prevalence of blaKPC in patient room sink drains located next to toilets (87.0%) when compared with sink drains located farther away from toilets (21.7%) using direct polymerase chain reaction assay. However, culture methods were only able to recover blaKPC-positive isolates from 16% of polymerase chain reaction-positive drains.

The purpose of this study was to compare nasal povidone-iodine swab for total joint arthroplasty patients to methicillin-resistant Staphylococcus aureus (MRSA) screening on the incidence of 90-day postoperative surgical site infections in total knee and hip arthroplasties as well as the cost-effectiveness. This is a single-center retrospective review of primary or revision total knee or hip arthroplasty patients. There were 849 patients screened for MRSA and 1004 patients in the nasal swab groups, both with an infection rate of 0.8%. The mean cost for the nasal swab was $27.21 (SD, 0), significantly different (P ≤ .01) than the mean cost for MRSA screens, $121.16 (SD, 26.18). There were significant cost savings with no difference in infection rates; therefore, nasal povidone-iodine swab antiseptic is financially and clinically successful.
