Errors in Abstract, Text, and Tables

For the Original Investigation titled “Effect of Integrating Machine Learning Mortality Estimates With Behavioral Nudges to Clinicians on Serious Illness Conversations Among Patients With Cancer: A Stepped-Wedge Cluster Randomized Clinical Trial,”¹ published online on October 15, 2020, and in the December 2020 issue of JAMA Oncology, the authors found an inadvertent programming error involving a single incorrect character that resulted in an overestimate of the number of high-risk patient encounters identified by the algorithm. This error affected statistics related to secondary outcomes of serious illness conversations and advance care planning conversations for high-risk patients in the abstract, main text, Tables 2 and 3, and Supplement 2. The authors corrected the error and repeated the analysis, which resulted in a slight change in the absolute values of findings related to high-risk patients that does not affect the interpretation of the study results. The article has been corrected online.
