†In Victoria, 8,036 SAB episodes were reported, resulting in a rate of 17.8/100,000. The final rate (27.0) for the entire state was extrapolated from this figure. The Victorian scheme is estimated to capture about two thirds of all bacteremia episodes that occur in that state per year.
‡System in place in Denmark since 1960, with numbers of episodes continually rising (e.g., in 1966, 400 per year and total population 4.8 million or 8/100,000). Collection data based on reviewing all discharge summaries and laboratory samples (15 of 16 counties). Associated 23% mortality rate in 2002, and 22% of these deaths were directly related to sepsis.
¶Compulsory reporting system. Unclear if all community onset episodes were included. In England, underreporting occurred with a voluntary system (only 13,770 episodes reported for 2003; thus, a 50% increase with compulsory system) (22).
#This rate is based on voluntary reporting system. Real rate might be 50% higher (22,24).
**Retrospective case analysis. Rate increased with age, urban areas, and African American ethnicity. 15% of community-onset SAB episodes were MRSA.
