  • Differentiate between the definition and clinical manifestations of mild, moderate, and severe SSTI.

  • Compare and contrast the clinical characteristics and presentation of a purulent vs nonpurulent SSTI.

  • Design an antimicrobial treatment regimen for purulent and nonpurulent SSTIs that are mild, moderate, or severe.

  • Develop monitoring parameters for nondrug and pharmacologic treatment of SSTIs.

  • Identify treatment modalities for decolonizing a patient with recurrent purulent SSTIs.


Chief Complaint

“I have a boil on my butt, and I cannot sit down for class.”


Jimmie Chipwood is a 19-year-old college student who presents to the ED with a new-onset “boil” on his right buttock. He noticed some pain and irritation in the right buttock area over the past week but thought it was due to having slid into second base during a baseball game. The pain gradually increased over the next few days, and he went to the student health center, where they cleaned the wound and gave him a prescription for clindamycin 300 mg QID for 7 days. They recommended he try to keep the area covered until the antibiotic began to work. Today (7 days later), Jimmie returned to the student health center for further evaluation and was referred to the ED for further care for his continued SSTI. At the ED, Jimmie says the area on his buttock is worse, and he cannot sit down for class. He reports only partial adherence to the clindamycin regimen, because he often forgets to take it and says it makes him nauseated.
