Cardiac complications following vascular or general surgery

Cardiac complications refer to any surgical complication involving the heart or the way the heart works.

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 cardiac complications 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 cardiac complication 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.

Note: While Northwestern Memorial results may be higher or lower than ACS NSQIP comparisons each period, our most recent performance is considered by ACS NSQIP to be "as expected" within the range expected for this surgical outcome.  Given the number of patients in the measure, the results are statistically the same. 

In this case, a lower number is better.
