Death within 30 days following vascular or general surgery
Mortality is a measure of the number of deaths (in general, or due to a specific cause).
All surgeries involve risk, including complications that may include death. While some patients have higher risks than others, some complications may be preventable.
About this measure
This measure tracks patients who experienced death 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 mortality 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" for this surgical outcome. Given the number of patients in the measure, the results are statistically similar than expected.
In this case, a lower number is better.
