The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was started by an act of the United States Congress in an attempt to decrease excessive mortality among patients within the Veterans Health Administration system. Currently, more than 200 hospitals participate in the ACS-NSQIP system. The focus of the program has been mainly on general surgery and vascular surgery procedures. A key part of ACS-NSQIP has been the recognition of the need for adjustment for patient-specific illness severity.
