[Forced centralized allocation in the emergency department-what has the COVID-19 pandemic changed?]

IVENA eHealth (IVENA, interdisziplinärer Versorgungsnachweis, mainis IT-Service GmbH, Offenbach am Main, Germany) supports the coordination of emergency admissions by providing real-time data on treatment options in hospitals. Overload or technical problems can lead to hospitals having to temporarily deregister parts or the entire emergency department, which can lead to acute admissions. The COVID-19 pandemic may have further exacerbated the situation, which was analyzed as part of this study.

This descriptive analysis used the IVENA eHealth information technology (IT) system to examine the occupancy and acute occupancy figures in the Munich ambulance service area from 2016-2022. Particular attention was paid to inpatient (SC II) and shock room + admissions in the specialties of internal medicine, neurology, trauma surgery and urology, as well as the development of acute occupancies, especially after the COVID-19 pandemic.

During the COVID-19 pandemic in 2020, the number of patients in the surveyed specialist areas fell by 23.7% (2021: -15% and 2022: -11% compared to 2019). The proportion of acute admissions fell in 2020 compared to 2019 (5.9% acute admissions vs. 6.8%) and rose disproportionately in 2021 (7.7% vs. 6.8%) and 2022 (24.9% vs. 6.8%).

There are many reasons for the increase in acute admissions, including the increase in inpatient admissions, the bottleneck in transferring patients (exit block) and the shortage of staff in the healthcare system. The COVID-19 pandemic has exacerbated some of these problems, which could explain the increase in acute admissions. A combination of different solutions is now needed to ensure adequate emergency care.
