Abstract
<i>Staphylococcus aureus</i>: The Persistent Pathogen
Highlights
Laupland et al [2] recently examined the epidemiology of invasive S aureus (ISA) infections in a population-based surveillance study within the Calgary Health Region from May 1999 to May 2000
Evidence suggests that the rates of nosocomial and communityacquired S aureus bacteremia have risen over time, no doubt related to the increasing complexity of patient problems and the invasive devices used in providing care
Steinberg et al [5] found that the rate of nosocomial S aureus bacteremia and community-acquired bacteremia increased from 0.75 cases/1000 discharges to 2.80 cases/1000 discharges and from 0.84 cases/1000 discharges to 2.43 cases/1000 discharges, respectively, between the two time frames
Summary
Laupland et al [2] recently examined the epidemiology of invasive S aureus (ISA) infections in a population-based surveillance study within the Calgary Health Region from May 1999 to May 2000. The overall mortality rate was 34% and trended toward being higher in patients with community-acquired SAB. A higher mortality rate was observed in patients with complicated bacteremia, primary bacteremia, or endocarditis.
