Colon surgery outcomes

What is colon surgery?

During surgery on the colon, which is also called the large intestine or large bowel, surgeons take out parts of the colon that are being affected by polyps, diverticula, tumors, or other conditions.

What does this measure show?

This measure tracks patients who experienced serious problems or death within 30 days of having colon surgery. It is based on a sampling method created by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).

Serious problems from colon surgery can include heart attack, infections, blood clots, stroke, pneumonia, kidney failure, breathing support needs.

The rate of serious problems or death for colon surgery patients is shown as an odds ratio. This reports the estimated odds of a serious problem or death occurring at Northwestern Memorial compared to the estimated odds of the same serious problem occurring in all hospitals in the ACS NSQIP database.

For this measure, a lower number is better.
