Results from a recently published study demonstrated MRSA-colonized patients who underwent total hip arthroplasty or total knee arthroplasty had a significantly increased risk of surgical site infection compared with non-MRSA carriers.
Researchers performed a retrospective analysis of 3,347 patients who underwent THA and 3,266 patients who underwent TKA. Patients preoperatively colonized with MRSA were identified. Investigators compared infection rates been MRSA carriers and non-MRSA carriers.
There was a colonization rate of 1.3%. Investigators noted 79 patients confirmed eradication of carrier status prior to surgical intervention. Of these patients, 38 underwent THA and 41 underwent TKA. Of the 79 patients, five developed a deep surgical site infection within 1 year postoperatively.
In patients who underwent THA, two had MRSA infections. In patients who underwent TKA, there were two MRSA infections and one methicillin-sensitive Staphylococcus aureus infection. According to researchers, the MRSA-negative control group had a significant statistical difference in infection rates, with a 1.7% deep sepsis rate in 1.17% of THAs and 1.3% in TKAs. – by Monica Jaramillo
