Evaluation of a "do not resuscitate" policy in intensive care.

The decision to withhold cardiopulmonary resuscitation from a patient within an intensive care unit (ICU) may be a difficult but appropriate one for which there are few guidelines. We describe the formulation of a Do Not Resuscitate (DNR) policy in our multidisciplinary ICU. To evaluate the effect of implementation of the DNR policy on physician practice and on communication among physicians, nurses, patients and their families, we interviewed physicians and nurses caring for patients designated DNR before (n = 8) and after (n = 17) implementation of the DNR policy. We found that DNR orders in the ICU were not infrequent (2-3 per week). All patients designated DNR were either irreversibly ill or not responsive to maximal therapy, and 22 of 25 were not competent. The DNR order was not accompanied by withdrawal of other therapy in 50% of cases and one patient recovered and was discharged from hospital. The implementation of the DNR policy encouraged greater physician consultation with other physicians, patients and their families. Although there were differences in perception of communication between physicians and nurses, we believe that the DNR policy influenced physician practice and enhanced overall communication in the ICU.
