The authors discuss delirium and its core outcomes in critically ill patients. Other topics include the effectiveness of standardization of interventions like intensive care unit (ICU) liberation in improving patient outcomes, the systematic review by their Delirium Core Outcome Set (COS) team to find effective ways to prevent or treat delirium, and the effectiveness of COS in enhancing homogeneity of outcome selection.
