The evaluation of nasal mupirocin to prevent Staphylococcus aureus burn wound colonization in routine clinical...

Area of Science:

• Infection Control
• Burn Care
• Microbiology

Background:

• Staphylococcus aureus colonization is common in burn patients, leading to impaired wound healing.
• Nasal mupirocin may reduce endogenous S. aureus colonization, while blocking exogenous routes can prevent cross-infection.
• This study investigates the efficacy of routine nasal mupirocin in reducing S. aureus burn wound colonization.

Purpose of the Study:

• To evaluate the effectiveness of routine nasal mupirocin application in patients and personnel for reducing S. aureus burn wound colonization.
• To determine if S. aureus nasal carriage is a risk factor for burn wound colonization.

Main Methods:

• Three study groups were established: Control, Mupirocin (patients treated), and Mupirocin+Personnel (patients and staff treated).
• Nasal mupirocin was administered to patients upon admission and to personnel identified as S. aureus carriers.
• Patients with nasal S. aureus but no wound colonization were analyzed for susceptibility to mupirocin treatment.

Main Results:

• The S. aureus burn wound colonization rate was consistent across all study groups for susceptible patients.
• Staphylococcus aureus nasal carriage was identified as a significant independent risk factor for burn wound colonization (OR: 3.3; 95% CI: 1.4-7.6).

Conclusions:

• Despite S. aureus nasal carriage being a significant risk factor, routine nasal mupirocin did not effectively reduce burn wound colonization.
• Further strategies may be needed to mitigate S. aureus colonization in burn wound settings.
