American College of Surgeons National Surgical Quality Improvement Program® surgical outcome measures
The American College of Surgeons (ACS) surgical outcome measures show whether hospitals differ in what happens to patients after they have 1 of 3 types of surgeries. Hospitals voluntarily report data on these measures as part of the ACS National Surgical Quality Improvement Program® (ACS NSQIP®) Exit Disclaimer - Opens in a new window. The surgical groups and outcomes are:
- Lower extremity bypass (LEB) surgical outcomes - During lower extremity bypass operations, surgeons insert a new vein to go around blockages in the arteries and restore blood flow to the lower leg and foot
- Colon surgical outcomes – During colon (large intestine) surgery, the surgeon removes part of the colon that is affected by polyps, diverticula, or tumors
- Outcomes in surgeries for patients 65 or older - Older patients have higher risks for death or complications than younger patients undergoing the same operation
The measures compare hospitals based on deaths or serious complications that occur within 30 days after each type of surgery. The serious complications vary by measure, but generally include:
- Cardiac (heart) problems
- Blood clots
- Renal (kidney) failure
- The need for breathing support
These measures are risk adjusted, meaning they take into account any differences among hospitals in the difficulty of surgeries that they attempt or how sick their patients were at the time of surgery. Each hospital is assigned to 1 of 3 quality categories: Better than Average, Average, and Worse than Average. These categories reflect the care a hospital provides before, during, and after surgery to reduce the number of serious complications or deaths that their patients experience after surgery.
You can use this information when deciding where to have surgery.
