ABSTRACT

BACKGROUND: No systematic study has previously been undertaken in Germany to ascertain why irreversible brain death determination (BDD) has not been carried out. OBJECTIVE: A comprehensive analysis of reasons for unperformed BDD in deceased patients with acute, severe brain damage could improve the identification of potential organ donors. METHOD: Using the Transplantcheck program of the German Organ Transplantation Foundation (DSO) an analysis of the data from 2016 was undertaken in participating hospitals in Saxony, Saxony-Anhalt and Thuringia (Region East of the DSO), regarding why a BDD was not initiated in deceased patients with primary or secondary brain damage. RESULTS: In 128 of the 144 Region East hospitals, 7889 deceased patients with primary or secondary brain damage were detected. In 7389 patients a BDD was out of the question for a variety of reasons. In 232 patients organ donation was not considered due to an advance directive. In 195 cases treatment was limited based on the patient's infaust neurological prognosis without the possibility of organ donation being discussed with relatives. In 73 cases initiation of BDD was indicated but not performed. CONCLUSION: The number of potential organ donors in Region East of the DSO could be significantly increased by identifying patients where BDD is indicated. By consistent evaluation of patients' wills in terms of organ donation before treatment is withdrawn in patients with poor neurological prognosis, additional potential organ donors could be identified. Furthermore, involving neurointensive care physicians in the care of all patients with brain damage could improve the prognostic assessment.
