AGSEM = Intensivists with base specialty training in Anesthesia, General Surgery or Emergency Medicine; DNR = Do Not Resuscitate; ICU = Intensive Care Unit; IM = Intensivists with base specialty training in Internal Medicine; IQR = Interquartile Range; LOS = Length of Stay; NS = non-significant; Pulm = Intensivists with base specialty training in Pulmonary Medicine.
