Objective: To assess the impact of the lockdown in Germany due to the COVID-19-pandemic on the incidence and the outcome of neurotrauma emergencies at a tertiary medical center. Material and Methods: From March 16th, 2020 (first lockdown in Germany) to January 31st, 2021, all neurosurgical emergencies were included and compared to a longitudinal case-cohort. Cases were descriptively recorded and retrospectively analyzed with respect to incidence and outcome. Results: All emergencies defined as polytrauma referred to our center decreased by 10% during the pandemic (n=226), whereas neurosurgical emergencies increased by 18.4% (764 vs. 905 cases). Number of specific neurotrauma emergencies increased by 44.4% (63 vs. 91 cases), yet statistically not significant (p=0.245). The duration of treatment in the intensive care unit (ICU) extended from 621 to 1056 days (p=0.34). Conclusion: Reasons for increasing numbers of neurotrauma emergencies were: 1) many surrounding smaller care providers were cancelled during this time, and 2) there was a lack of free intensive care capacities in other hospitals, urging primarily maximum care providers to deal with more referrals. Both these facts and the prolonged treatment on ICUs strenghten the necessity for maximum care providers to keep ICU capacities for non-COVID patients. Specialized neurosurgical expertise should maintain in tertiary medical centers, even or particularly in exceptional circumstances such as the current pandemic.
