Early Identification of Patients With Out-of-Hospital Cardiac Arrest With No Chance of Survival and Consideration for Organ Donation.
Annals of Internal Medicine 2016 December 7
Background: In patients with out-of-hospital cardiac arrest (OHCA), care requirements can conflict with the need to promptly focus efforts on organ donation in patients who are pronounced dead.
Objective: To evaluate objective criteria for identifying patients with OHCA with no chance of survival during the first minutes of cardiopulmonary resuscitation to enable prompt orientation toward organ donation.
Design: Retrospective assessment using OHCA data from 2 registries and 1 trial.
Setting: France (Paris Sudden Death Expertise Center [SDEC] prospective cohort [2011 to 2014] and PRESENCE multicenter cluster randomized trial [ClinicalTrials.gov: NCT01009606] [2009 to 2011]) and the United States (King County, Washington, prospective cohort [2006 to 2011]).
Patients: 1771 patients from the Paris SDEC 1-year cohort (2011 to 2012) and 5192 from the validation cohorts.
Measurements: Evaluation of 3 objective criteria (OHCA not witnessed by emergency medical services personnel, nonshockable initial cardiac rhythm, and no return of spontaneous circulation before receipt of a third 1-mg dose of epinephrine), survival rate at hospital discharge among patients meeting these criteria, performance of the criteria, and number of patients eligible for organ donation.
Results: In the Paris SDEC 1-year cohort, the survival rate among the 772 patients with OHCA who met the objective criteria was 0% (95% CI, 0.0% to 0.5%), with a specificity of 100% (CI, 97% to 100%) and a positive predictive value of 100% (CI, 99% to 100%). These results were verified in the validation cohorts. Ninety-five (12%) patients in the Paris SDEC 1-year cohort may have been eligible for organ donation.
Limitation: Several patients had unknown outcomes.
Conclusion: Three objective criteria enable the early identification of patients with OHCA with essentially no chance of survival and may help in decision making about the organ donation process.
