ABSTRACT
Objective: COVID-19 lockdowns in 2020 limited activities of daily life. Data on the impact on healthcare systems is ambiguous. So far no data has been published for pediatric neurosurgery in Germany. We present the results of a big data approach. Method(s): We obtained anonymous data from the nationwide database of hospital statistics (German Federal Statistical Office, www. desta tis. de) in August 2022. For the age group <18 years in 2016- 2020, the following diagnoses (ICD-10 code) were analysed: Intracranial injury (S06), malignant (C71), benign (D33) and unspecified (D43) neoplasia, abuse (T74), violent attack (Y09) and, for comparison, forearm fracture (S52). The following operations (OPS code) were chosen: Operation of the central nervous system (CNS, 5-01- 05), excision of intracranial lesion (5-015), shunt insertion (5-023), shunt revision (5-024), plastic operations of the spinal cord (5-036) and, for comparison, overall number of operations (OPS-5), spondylodesis (5-836) and functional neurosurgery (5-028) at all ages. Result(s): The number of operations declined from 17.23 million in 2019 to 15.82 million in 2020 (8.2%). CNS operations declined by 5%. Shunt insertion declined by 8.1%, revision by 5.1% and spinal cord operations by 6.6%, whereas excisions of intracranial lesions increased by 1.7%. Spondylodesis and functional operations both decreased by 11.9%. The hospitalisations for intracranial neoplasia declined by 8.8% compared to previous years. The number of inpatients with intracranial injury declined by 16%. Violent attack was also documented less often (-13.2%), but child abuse increased by 3.3%. Forearm fractures declined by 5.6%. Conclusion(s): The COVID-19 lockdown in 2020 lead to reduction of operations. Neuro-oncological operations were not affected. Intracranial injury even declined by 16%, reflecting limited activities and mobility. An increase in documented child abuse by 3.3% compared to the average of previous years was observed. These results help understand the impact of pandemics and political decisions and guide future decision-making.
