The article, “Preoperative Frailty Assessment, Operative Severity Score, and Early Postoperative Loss of Independence in Surgical Patients Age 65 Years or Older,” which appeared in the April 2021 issue of the Journal of the American College of Surgeons, Volume 232, Issue 4, pages 387–395, incorrectly named the scoring system discussed. “Operative Severity Score” was used in the title and throughout the article, however the correct name of the scoring system is “Operative Stress Score”. The authors apologize for this error.
The article has been updated online to reflect this change.
