Bilimoria said he's been working with CMS to include the calculator in the final rule, which is expected sometime next month.
"CMS realizes the importance of providing patients with empirical data-driven risk factors. They're going to incentivize surgeons who want to use this by letting it meet a PQRS requirement."
The new risk calculator is based on the ACS's National Surgical Quality Improvement Program (NSQIP) program, through which hundreds of hospitals are participating in confidential quality improvement programs for certain kinds of surgical care.
Participants share best practices and help other surgeons in their own hospitals as well as across the country, learn ways to improve outcomes. The calculator's formula was generated from outcomes from about 1.4 million patient procedures at nearly 400 participating NSQIP hospitals between Jan. 1, 2009 and June 30, 2012.
A paper detailing how the risk calculator was created is due to be published in the Journal of the American College of Surgeons in the near future. It is already posted online.
