title: Prevalence of methicillin-resistant Staphylococcus aureus in the setting of dermatologic surgery.
abstract: BACKGROUND
  The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the postoperative setting of dermatologic surgery is unknown. Such data could influence the empirical treatment of suspected infections.
  
  
  OBJECTIVE
  To examine the period prevalence of MRSA infections in the postoperative setting of dermatologic surgery.
  
  
  METHODS
  We performed chart reviews of 70 patients who had bacterial cultures taken from January 2007 to December 2007. In the 21 postsurgical cases, we analyzed age, risk factors, sites of predilection, method of repair, and pathogen of growth.
  
  
  RESULTS
  The mean age of the overall study population was 57, with the mean age of postsurgical MRSA-positive cases being 75.5. Of the 21 postsurgical cultures taken, 16 cultures grew pathogen, and two of the 16 (13%) pathogen-positive cultures grew MRSA.
  
  
  CONCLUSIONS
  This is a retrospective chart review of a relatively small sample size in one geographic location. Our patient population is known to contain a large number of retirees.
  
  
  CONCLUSIONS
  The increasing prevalence of MRSA skin and soft tissue infections and recommendation to modify empirical antibiotic therapy have been well documented in particular patient populations, but we caution against the empirical use of MRSA-sensitive antibiotics in the postoperative setting of dermatologic surgery. We advocate culturing all infectious lesions upon presentation and reserve empirical use of MRSA-sensitive antibiotics for high-risk patients or locations.
