Practice and Predictors of Do-Not-Resuscitate Orders in a Tertiary-Care Intensive Care Unit in Saudi Arabia
Table 2
Predictors of do-not-resuscitate (DNR) status (multivariable logistic regression analysis). The independent variables entered in the model were age, premorbid WHO performance status, admission category, sepsis, ischemic stroke, hemorrhagic stroke, chronic cardiovascular disease, chronic renal disease and chronic respiratory disease, APACHE II and admission year.
