Just the Facts: Methicillin-resistant Staphylococcus aureus and soft tissue abscess in the emergency department
1Queen's University, Department of Emergency Medicine, Kingston, ON.
Abstract:
Soft tissue abscess used to be an easy emergency department (ED) presentation: perform an incision and drainage (I + D) and discharge your patient. Times have changed. Methicillin-resistant Staphylococcus aureus (MRSA) is now a major cause of soft tissue abscess in ED patients. MRSA is, by definition, resistant to cloxacillin and cephalosporins. Almost all Canadian strains are susceptible to vancomycin and linezolid. MRSA strains are variably susceptible to trimethoprim-sulfamethoxazole (TMP-SMX), tetra/doxycycline, and clindamycin, with pooled Canadian clindamycin resistance just over 40%.
