  Purpose

Staphylococcus aureus is the most common bacteria responsible for skin, bone, and muscle infections. Recent studies from the United States have suggested that a type of this bacterium called methicillin resistant S. aureus (MRSA) has become dramatically more common, especially the community strain. However, Canadian data is still largely lacking. This study aims to determine the prevalence of community acquired (CA) MRSA among patients presenting with skin and soft tissue infections to the Urgent Care Center and Emergency Departments in London, Ontario. This will be determined by taking swabs at enrollment from patient's noses, throats, and sites of infection. Patients will be asked to complete a health questionnaire with the goal of identifying risk factors associated with CA-MRSA. Through follow-up swabs of participants' noses and throats at one and three months, the effects of treatment on patient's carrying MRSA will be determined. Results may be used to form guidelines for empirical S aureus treatment in the region, reducing possible morbidity and mortality from delayed or suboptimal treatment of CA-MRSA infections. Improved understanding of risk factors associated with MRSA infection in a Canadian setting, may also change the practice of physicians considering empiric antibiotic therapy for skin and soft tissue infections.

Study Population

Selection of Participants: The objective of this prospective study is to determine the prevalence of MRSA and community acquired MRSA (CA-MRSA) in adult patients (>17 yrs old) presenting with skin or soft tissue infections to the emergency departments (EDs) of an academic health care setting in London, Ontario.

Criteria

Inclusion Criteria:

  • All adult patients (> 17 years) whose chief complaint is consistent with skin or soft tissue infection (cellulitis, necrotizing soft tissue infection, wound infection, ulcer, septic bursitis, abscess including furuncle/carbuncle/superficial skin abscess, paronychia, hordeolum, pilonidal abscess, acute lymphadenitis, pilonidal cyst without abscess, and impetigo).

Exclusion Criteria:

  • Patients will be excluded if they refuse to participate or written, informed consent is not obtained.
  • Additionally, patients with Bartholin cysts, odontogenic infections and perianal abscesses will be excluded.
