Key Points

Recently there has been a dramatic increase in the frequency and severity of skin and soft-tissue infections (SSTIs) accompanied by the emergence of resistance to many of the antimicrobial agents commonly used to treat skin and soft-tissue infections in the past.
  • There was a 29% increase in the total hospital admissions for these infections between 2000 and 2004.
  • 6.3 million physician’s office visits per year are attributable to SSTIs.
  • Between 1993 and 2005, annual emergency department visits for SSTIs increased from 1.2 million to 3.4 million patients.
    • Some of this increased frequency is related to the emergence of community associated methicillin-resistant S. aureus (MRSA).
Clinical evaluation of patients with SSTI aims to establish the cause and severity of infection and must take into account pathogen-specific and local antibiotic resistance patterns.

When developing an adequate differential diagnosis and an appropriate index of suspicion for specific etiological agents it is essential to obtain a careful history that includes information about the patient’s immune status, geographical locale, travel history, recent trauma or surgery, previous antimicrobial therapy, lifestyle, hobbies, and animal exposure or bites.

Recognition of the physical examination findings and understanding the anatomical relationships of skin and soft tissue are crucial for establishing the correct diagnosis.

When information from history and physical are insufficient, biopsy or aspiration of tissue may be necessary, and radiographic procedures may be critical to determine the level of infection and the presence of gas, abscess or a necrotizing process.

Surgical exploration or debridement is an important diagnostic as well as therapeutic procedure in patients with necrotizing infections or myonecrosis.
