MRSA increases the risk of mortality in patients with surgical site infections1
Unadjusted incidence of mortality during the 90-day postoperative period*
[NOTE: P=.04 (vs. control) above ↑ per reference]
* Not adjusted to account for other predictors of mortality among the
S. aureus SSI group including, but not limited to, increasing age, American Society of Anesthesiologists score, duration of surgery, National Nosocomial Infection Surveillance risk index, and length of hospital stay before infection.
- Multivariate analysis confirmed MRSA significantly increased the risk of mortality by 3-fold compared with MSSA in SSI (P=.003)
