A Retrospective Study of the Association of Different Levels of Resuscitation Orders and Mortality in ICU Patients.

The hypothesis of the study is that a resuscitation order other than full code is associated with increased mortality among critically ill patients. By incorporating conventional variables associated with death such as age, sex, and Simplified Acute Physiological Score, as well as including the new Clinical Frailty Scale in a statistical model, the aim is to investigate whether there is still an increased risk of death that remains unexplained.
