Failure to Report Related Studies

To the Editor On behalf of my coauthors, I write to report our failure to include discussion of and reference to previously published, related articles in our Original Investigation titled, "Risk Factors Associated With Postoperative Delirium in Patients Undergoing Head and Neck Free Flap Reconstruction," which was published online in the January 3, 2019, issue of JAMA Otolaryngology–Head & Neck Surgery. In this study, we analyzed a cohort of 515 patients who had undergone free flap reconstruction at The Ohio State University Comprehensive Care Center (2006-2012) to assess risk factors associated with development of postoperative delirium after surgery. We identified a number of risk factors, including preoperative alcohol abstinence as predictor associated with a reduced risk of postoperative delirium.
