Objective: Methicillin resistant Staphylococcus aureus (MRSA) is the most common cause of postoperative infection in instrumented fusion surgery. Although MRSA is well-known cause of nosocomial infection, emerging evidence supports that there could be MRSA infection from community. This study evaluated the nasal colonization rate of MRSA among healthy adults within the age range of spinal fusion surgery in Korea.
Methods: Nasal swabs were collected from 99 participants who visited health promotion center. A structured questionnaire regarding healthcare-associated MRSA risk factors was collected simultaneously. Staphylococcus aureus was confirmed by latex agglutination. The resistance to methicillin was identified by oxacillin screening test.
Results: Of the 99 participants, 12 (12.1%) had S. aureus isolates. The nasal carriage rate of methicillin susceptible S. aureus (MSSA) was 9 (9.1%). MRSA was identified in 3 participants (3.0%).
Conclusion: Among the age range of possible spinal fusion surgery, nasal colonization study revealed substantial rate of preoperative MRSA carriers even in healthy adults. A postoperative MRSA infection should not be exclusively considered to be due to surgery-related contamination.
