Readmission after general or vascular surgery
Readmission occurs when patients who have had a recent hospital stay need to go back into a hospital again. Readmission after surgery occurs if a patient returns to a hospital within 30 days of their surgery.
About this measure
This measure tracks patients who had general or vascular surgery and were readmitted to the hospital, based on a sampling methodology developed by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).
The rate of readmission for general or 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.
