['Medical emergency teams frequently implement do not resuscitate orders, but little is known about end-of-life care in this population.', 'To examine resource utilization and end-of-life care following medical emergency team-implemented do not resuscitate orders.', 'Retrospective review.', 'Single, tertiary care center.', 'Consecutive adult inpatients requiring a medical emergency team activation over 1 year.', 'Changes to code status, time spent on medical emergency team activations, frequency of palliative care consultation, discharges with hospice care.', 'None.', 'We observed 1156 medical emergency team activations in 998 patients. Five percent (58/1156) resulted in do not resuscitate orders. The median time spent on activations with a change in code status was longer than activations without a change (66 vs 60 minutes, P = 0.05). Patients with a medical emergency team-implemented do not resuscitate order had a higher inpatient mortality (43 vs 27%, P = 0.04) and were less likely to be discharged with hospice at the end of life than patients with a preexisting do not resuscitate order (4 vs 29%, P = 0.01). There was no difference in palliative care consultation in patients with a preexisting do not resuscitate versus medical emergency team-implemented do not resuscitate order (20% vs 12%, P = 0.39).'] Do resource utilization and end-of-life care in a US hospital following medical emergency team-implemented resuscitate orders?
