Abstract
Background: Staphylococcus aureus is the most common and most important pathogen following knee and hip arthroplasty procedures. Understanding the epidemiology of invasive S. aureus infections is important to quantify this serious complication.
Methods: This nested retrospective cohort analysis included
adult patients who had undergone insertion of knee or hip prostheses with clean
or clean-contaminated wound class at 11 hospitals between 2003-2006. Invasive
S. aureus infections, non-superficial incisional surgical site infections
(SSIs) and blood stream infections (BSIs), were prospectively identified
following each procedure. Prevalence rates, per 100 procedures, were estimated.
Results: 13,719 prosthetic knee (62%) and hip (38%) insertion
procedures were performed. Of 92 invasive S. aureus infections identified, SSIs
were more common (80%) than SSI and BSI (10%) or BSI alone (10%). The rate of
invasive S. aureus infection/100 procedures was 0.57 [95% CI: 0.43-0.73] for
knee insertion and 0.83 [95% CI: 0.61-1.08] for hip insertion. More than half
(53%) were methicillin-resistant. Median time-to-onset of infection was 34 and
26 days for knee and hip insertion, respectively. Infection was associated with
higher National Healthcare Safety Network risk index (p ≤ 0.0001).
Conclusions: Post-operative invasive S. aureus infections were rare, but
difficult-to-treat methicillin-resistant infections were relatively common.
Optimizing preventative efforts may greatly reduce the healthcare burden
associated with S. aureus infections.
