Outcomes in surgeries for patients 65 years of age or older

How is surgery different for patients 65 years of age or older?

Older patients are more at risk for death or serious problems than younger patients who have the same surgery.

What does this measure show?

This measure tracks patients who are 65 years of age or older who experienced serious problems or death within 30 days of having surgery. It is based on a sampling method developed by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).

Serious problems from surgery for patients who are 65 years of age or older can include heart attack, infections, blood clots, stroke, pneumonia, kidney failure, breathing support needs.

The rate of serious problems or death for surgery patients who are 65 years of age or older 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.
