Surgical site infection following vascular or general surgery

A surgical site is the location of the incision made to access the part of the body being surgically removed, repaired or replaced. A surgical site infection is an infection of the skin and/or tissue in or around a surgical wound site that occurs after surgery.

All surgeries involve risk and the possibility of complications.  While some patients have higher risks than others, some complications may be preventable.

About this measure

This measure tracks patients who experienced surgical site infection after general or vascular surgery, based on a sampling methodology developed by the American College of Surgeons National Surgical Quality Improvement Program (NSQIP).

The surgical site infection rate for general and vascular surgery patients is expressed as an odds ratio. This reports the estimated odds of an event happening at Northwestern Memorial compared to the estimated odds of that event happening in all hospitals in the ACS NSQIP database. A number of 1.0 means the hospital is performing as expected. A number less than 1.0 means the hospital is performing better than expected. A number greater than 1.0 means the hospital is performing worse than expected.

In this case, a lower number is better.
