Coding Errors in Survey Study of Best Practices for In-Hospital Cardiac Arrest

To the Editor On behalf of our coauthors, we write to report errors that occurred in the survey study in our article, “Resuscitation Practices Associated With Survival After In-Hospital Cardiac Arrest: A Nationwide Survey,”¹ published online April 6, 2016, and in the May 2016 issue of JAMA Cardiology. Unfortunately, we recently became aware of administrative errors in categorizing several hospitals’ risk-standardized survival rate for in-hospital cardiac arrest while conducting additional analyses.
