Surgical Site Infections (SSI)

Data & Statistics for Surgical Site Infections

As of 1999, in the United States alone, an estimated 27 million surgical procedures are performed each year. The CDC’s National Nosocomial Infections Surveillance (NNIS) system, established in 1970, monitors reported trends in nosocomial infections in U.S. acute-care hospitals.
Based on 1993 NNIS system reports, SSIs are the third most frequently reported nosocomial infection, accounting for 14% to 16% of all nosocomial infections among hospitalized patients.
