Empiric treatment is less costly than Staphylococcus aureus screening and decolonization in total joint arthroplasty patients

摘要

The aim of our study was to compare the cost of preoperative empiric mupirocin treatment of all total joint arthroplasty patients with a standard Staphylococcus aureus screening and decolonization protocol. The cost of empiric mupirocin treatment is $24.65 per patient, whereas the cost of a standard S. aureus screening and decolonization protocol is $60.32 per patient. Given that more than 1,051,000 total joint arthroplasties are performed annually, the cost savings with empiric treatment is nearly $40 million per year. Empiric treatment allows for more efficient workflow, minimizes potential for clerical error, eliminates risk of undertreatment, and has not been shown to increase antibiotic resistance.
