Impact of the COVID-19 pandemic on brain death detection in German hospitals: a state-wide analysis of health data

Abstract Background The low rate of organ donation in Germany has been linked to a deficit in the detection of patients with brain death (BD) in hospitals. It is unclear how crisis-related health system disruptions, such as the COVID-19 pandemic, affect this detection deficit. Methods Secondary data analysis of anonymized data from deceased patients with acute brain injury from Saxony, Saxony-Anhalt and Thuringia during the pre-pandemic and pandemic period (01/2019–12/2022). Pandemic phases were stratified according to the predominant SARS-CoV-2 variant. Logistic multilevel models were employed to assess outcomes including diagnosis of BD, deceased organ donations, missed cases with potential BD and organ donation-related interactions with the German Organ procurement organization. Models accounted for regional COVID-19 incidence and first-dose vaccination rates, as well as age, gender and types of brain injuries. Results A total of 11,100 deceased individuals from 136 hospitals were analyzed. An inverse association was observed between COVID-19 incidence and the determination of BD (adjusted odds ratio [aOR] 0.94, 95%CI [0.91; 0.97]; p
