We examined the process, consequences and impact of writing a Do-Not-Resuscitate (DNR) order in a cohort of critically-ill ICU patients. Special emphasis was given to the DNR order including withholding renal replacement therapy. A DNR code was mainly written in the first week following ICU admission and more often given to medical, older and sicker patients. ⋯ In our population, the final in-hospital mortality rate of DNR-coded patients was 100%, because the DNR status was ordered when the patients were already very sick. DNR-coded patients died after a longer mean length of ICU stay than patients without a code. Withholding renal replacement therapy was commonly added to the DNR order even if renal failure either was not present or never developed.
