Complications or morbidity within 30 days following vascular or general surgery

Morbidity refers to the state of being sick or unhealthy due to any cause. Surgical morbidity refers to being sick or unhealthy after a surgical procedure. Morbidity can be a complication of a surgery.

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

About this measure

This measure tracks patients who experienced complications or other illnesses within 30 days after general or vascular surgery, based on a sampling methodology developed by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).

The 30-day morbidity 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.
