HAI Profile

Colon Surgical Site Infections

When germs get into an area where surgery is or was performed, patients can get a surgical site infection (SSI). Colon surgeries are one of two SSIs that are reported by all or most acute care hospitals in most U.S. states. Healthcare-associated infections (HAIs) are infections that patients can get while receiving medical treatment in a healthcare facility. Working toward the elimination of HAIs is a CDC priority. The CDC provides national data on infection rates through the National Healthcare Safety Network. Standardized Infection Ratios (SIRs) are summary statistics that allow monitoring of HAIs over time.

The Standardized Infection Ratio for Colon Surgical Site Infections was 0.85 across general acute care hospitals in 2019.


  • Data profiles for Healthcare-Associated Infections include information for Central Line-Associated Bloodstream Infection (CLABSI), Catheter-Associated Urinary Tract Infection (CAUTI), Surgical Site Infections (SSI), Clostridioides difficile (C. difficile) infections, MRSA Bacteremia, and Ventilator-Associated Events (VAE).
  • All HAI data provided on this page are maintained by the CDC's National Healthcare Safety Network (NHSN).
  • Data are only displayed for U.S. states/territories for which at least 5 facilities reported an HAI in the given report year.
  • HAI information available in the Patient Safety Portal include data from 2015 through 2019.
  • Map legends are classified using the Jenks Natural Breaks method.
  • See the Current HAI Progress Report Technical Appendix for the full methodology and details about the data. Past HAI Progress Reports are described in the Data Archive.
