American College Of Surgeons - Inspiring Quality: Highest Standards, Better Outcomes

Hospital Compare

October 2020 Results

In order to provide proven and stronger quality information, the American College of Surgeons (ACS) has partnered with the Centers for Medicare & Medicaid Services (CMS) to allow ACS NSQIP® hospitals across the country the opportunity to report surgical outcomes to Hospital Compare, the CMS website that provides quality information to healthcare consumers. The program provides hospitals participating in the ACS NSQIP Adult Program Options the chance to voluntarily, publicly report on one or any combination of three National Quality Forum (NQF)-endorsed measures—elderly surgery, colon surgical and lower-extremity bypass outcomes.

Information on the Hospital Compare website will explain the rigors of ACS NSQIP so that patients better understand what the measures mean; the importance of accurate, risk-adjusted data; and how to use the information in making their care decisions. Because ACS NSQIP is based on the best available data—clinical, risk- and case-mix–adjusted, nationally benchmarked and audited 30-day patient outcomes—the program provides arguably the most valid and reliable look at surgical quality. It provides a better gauge of quality than many other public measures, many of which are based on compliance with process measures or based on administrative data.

Registration will take place in electronic format only. Hospitals interested in participating in this program are required to submit an Addendum.  An Exhibit Form is also required for hospitals that share a CCN with another hospital. These documents only need to be submitted at the time of initial registration. Once these documents have been submitted, hospitals will be able to electronically select the measure(s) they wish to publically report to Hospital Compare. Your Authorized Institutional Signatory is responsible for submission of the Addendum and Exhibit Form. Measure selection can be completed by a designated hospital representative.
