The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) has recognized Massachusetts General Hospital as one of 89 ACS NSQIP participating hospitals across the country that have achieved meritorious outcomes for surgical patient care in 2019. As a participant in ACS NSQIP, Mass General is required to track the outcomes of inpatient and outpatient surgical procedures and collect data that assesses patient safety and can be used to direct improvement in the quality of surgical care.

“Congratulations to the physicians, residents, nurses and all other providers at Mass General who do such a great job in providing high-quality patient care. This is a testament to you,” says Keith Lillemoe, MD, chief of the Department of Surgery at Mass General.

The ACS is a scientific and educational organization of surgeons that was founded in 1913 to raise the standards of surgical practice and to improve the care of the surgical patient. ACS NSQIP is the only nationally validated quality improvement program that measures and enhances the care of surgical patients. This program measures the actual surgical results 30 days postoperatively as well as risk adjusts patient characteristics to compensate for differences among patient populations and acuity levels.


The ACS NSQIP recognition program commends a select group of hospitals for achieving a meritorious composite score in either an “all cases” category or a category that includes only “high risk” cases. Risk-adjusted data from the July 2020 ACS NSQIP Semiannual Report, which presents data from the 2019 calendar year, were used to determine which hospitals demonstrated meritorious outcomes. Mass General has been recognized on both the “all cases” and “high risk” meritorious lists.

Each composite score was determined through a different weighted formula combining eight outcomes. The outcome performances related to patient management were in the following eight clinical areas:

  • Mortality
  • Unplanned intubation
  • On the ventilator greater than 48 hours
  • Renal failure
  • Cardiac incidents—e.g., cardiac arrest and myocardial infarction
  • Respiratory—e.g., pneumonia
  • Surgical site infections (SSIs)—superficial and deep incisional and organ-space SSIs
  • Urinary tract infection

The 89 commended hospitals achieved the distinction based on their outstanding composite quality score across the eight areas listed above.

The ACS NSQIP has recognized Mass General as a national leader for surgical outcomes for four consecutive years—2016, 2017, 2018 and 2019.
