Abstract

Introduction: Prosthetic joint infection (PJI) is one of the most dramatic complications in total hip arthroplasty (THA). Among risk factors, nasal colonization with Staphylococcus Aureus (SA) has been described, showing an increasing prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) The aim of this study is to determine the prevalence of S. Aureus, MRSA nasal colonization before THA and to learn the relation to Charlson comorbidity index (CCI).

Methods: From a sample of patients from the community with osteoarthritis, we selected patients undergoing THA who met inclusion and exclusion criteria and were screened for nasal colonization of SA and antibiotic resistance, prior to surgery. A decolonization protocol with topic mupirocin and soapy chlorhexidine bathing was used in nasal carriers of SA. A new culture was performed two weeks after the treatment was completed. Finally, CCI was calculated.

Results: 106 patients met the inclusion and exclusion criteria. 24.5% (26) of patients were positive to nasal colonization to SA, 1.8% of them were positive to MRSA and all completed treatment. No positive cultures were obtained in the two-week follow-up, no statistically significant difference in the CCI between both groups was revealed and no PJI was reported at 6-month follow-up.

Discussion: In this study, the prevalence of nasal colonization S. Aureus and MRSA, was within the range reported in international literature. We suggest a universal detection of nasal carriage of SA in patients who will be undergoing a THA.
