Methicillin-resistant Staphylococcus aureus: decolonization and prevention prescribing practices for children treated with skin abscesses/boils in a pediatric emergency department

Abstract

Objective: This study aimed to describe methicillin-resistant Staphylococcus aureus (MRSA) eradication/prevention practices of clinicians managing patients with skin and soft tissue infections (SSTIs), specifically, in those patients undergoing abscess incision and drainage (I&D) in a pediatric emergency department (ED).

Methods: A retrospective cohort study was performed for children aged 0 to 18 years old undergoing I&D of cutaneous abscess between January 1, 2011, and December 31, 2011, in the Cincinnati Children's Hospital Medical Center ED.

Results: Five hundred seventy-five patients underwent abscess I&D during our study period. Approximately 25% of our population had previous history of MRSA, SSTI, or boil/abscess; in addition, 26% of our population had a household family member with a previous history of MRSA, SSTI, or boil/abscess. Wound cultures were obtained in 399 (69%) of 575 of I&D abscesses, and of these, 57% of the I&D abscesses grew MRSA. Of all patients, only 3.7% (21 patients) had documentation of MRSA eradication/prevention instructions for patient/family.

Conclusions: Methicillin-resistant S aureus eradication/prevention discussions are not commonly included in discharge instructions for patients undergoing abscess I&D. Given the significant proportion with previous MRSA infection, the ED may be a setting to provide instructions to patients/families with recurrent infections.
