Clinical Significance
Pre-operative screening for Methicillin Sensitive Staphlococcus aureus (MSSA) or Methicillin-Resistant Staphlococcus aureus (MRSA) colonization as an infection control measure.
Staph aureus is one of the leading causes of surgical site infection. The Centers for Disease Control and Prevention estimates that it accounts for 14% to 16% of all nosocomial infections. Nasal colonization with either S. aureus or MRSA has been demonstrated to be an important independent risk factor associated with increasing incidence and severity of surgical site infections after orthopedic surgery. Pre-surgical screening and subsequent decolonization of Methylicillin Sensitive or Methylicillin Resistant Staph aureus carriers has shown to be a cost-effective strategy to reduce post-surgical infections and resulting extended hospital stays.
