Risk Factors for Nosocomial MRSA Bacteremia Within 24 Hours of Hospital Admission

Purpose: To determine if a patient with MRSA bacteremia occurring within 24 hours of hospital admission has a nosocomial infection.

Description

Tacconelli et al identified risk factors for nosocomial methicillin-resistant Staphylococcus aureus (MRSA) occurring within 24 hours after hospital admission. It is not uncommon for these patients to be misclassified as having a community-acquired infection. The authors are from Beth Israel Deaconess Medical Center in Boston.


Risk factors for nosocomial MRSA bacteremia occurring within 24 hours of hospital admission:

(1) history of previous MRSA colonization and/or infection

(2) presence of cellulitis at the time of hospital admission

(3) presence of a skin ulcer at the time of hospital admission

(4) presence of a central venous catheter (CVC)

 

where:

• The odds ratio for a previous history was 17. The other factors had odds ratios ranging from 3.1 to 4.3.
