In the article, “Hospital Operative Volume and Quality Indication for General Surgery Operations Performed Emergently in Geriatric Patients,” by Becher and colleagues, which appeared in the June 2019 issue of the Journal of the American College of Surgeons, Volume 228, Number 6, pages 910e23, the title was incorrect. The correct title is, “Hospital Operative Volume as a Quality Indicator for General Surgery Operations Performed Emergently in Geriatric Patients.” The editors apologize for this error.
Additionally, in Appendix E, several tabulated cells were published incorrectly. The corrected Appendix E is presented below. The authors apologize for this error.
