Factors Associated With Surgical Mortality and Complications Among Patients With vs Without Coronavirus Disease 2019 (COVID-19)

This video barplot illustrates clinical factors associated with surgical mortality and complications at an Italian hospital in February and March 2020. Based on a classification tree analysis, it can be interpreted as a ranking from the most to least important variable, top to bottom. For patients without COVID-19, the analysis identified 5 variables related to complications (age, C-reactive protein levels, American Society of Anesthesiologist class, sex, and sepsis) that are well known and previously shown to be associated with surgical outcome. However, COVID-19 has the strongest association with complications and mortality and substantially reduced the importance of the other variables when added to the analysis.
