[Escalation and de-escalation concept for intensive care beds in hospitals reserved for COVID-19]. / Eskalations­/Deeskalationskonzept zur COVID-19-bedingten Freihaltung von Intensivkapazitäten an Kliniken.

BACKGROUND: Since the spread of Severe Acute Respiratory Syndrom Corona Virus 2 (SARS-CoV­2) in Germany, intensive care beds have been kept free for patients suffering from Corona Virus Disease (COVID-19). Also, after the number of infections had declined, intensive care beds were kept free prophylactically; however, the percentage of beds reserved for COVID-19 differ in the individual federal states in Germany. The aim of this article is to define a necessary clearance quota of intensive beds for COVID-19 patients in Germany. An escalation and de-escalation scheme was created for rising and falling numbers of infected patients. METHODS: Data from the COVID-19 resource board of the state of Baden-Württemberg, the daily situation report of the Robert Koch Institute (RKI), the register of COVID-19 intensive care beds of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) as well as the daily report of COVID-19 Baden-Württemberg from April to November 2020 were used for the calculation. RESULTS: At the end of November 2020 approximately 13.5% of intensive care beds in Germany were used by COVID-19 patients. Of all persons tested positive for SARS-CoV­2, 1.5% were admitted to an intensive care unit. The hospitalization rate was 6% and the mean age of infected persons was 43 years. Based on these numbers hospitals are recommended to keep 10% of intensive care beds available for COVID-19 patients in the case of less than 35 new infections/100,000 in the catchment area, 20% should be kept free in case of an advanced warning level of 35 new infections/100,000 inhabitants and 30% for a critical limit of 50 new infections/100,000 inhabitants. Further internal hospital triggers, such as the occupancy of the intensive care beds with COVID-19 patients, should be considered. CONCLUSION: If the number of infections is low a general nationwide retention rate of more than 10% of intensive care beds for COVID-19 patients is not justified. Locally increasing numbers of infections require a local dynamic approach. If the number of infections increases, the free holding capacity should be increased according to a step by step concept in close coordination with the local health authorities and other internal hospital triggers. In order not to overwhelm hospital capacities in the event of local outbreaks, a corresponding relocation concept should be considered at an early stage.

[Managing the pandemic-relocation concept for COVID-19 intensive care patients and non-COVID-19 intensive care patients in Baden-Württemberg]. / Die Pandemie bewältigen ­ Verlegungskonzept von COVID-19-Intensivpatienten und Non-COVID-19-Intensivpatienten in Baden-Württemberg.

BACKGROUND: A sharp rise in COVID-19 infections threatened to lead to a local overload of intensive care units in autumn 2020. To prevent this scenario a nationwide relocation concept was developed. METHODS: For the development of the concept publicly available infection rates of the leading infection authority in Germany were used. Within this concept six medical care regions (clusters) were designed around a center of maximum intensive care (ECMO option) based on the number of intensive care beds per 100,000 inhabitants. The concept describes the management structure including a structural chart, the individual tasks, the organization and the cluster assignment of the clinics. The transfers of intensive care patients within and between the clusters were recorded from 11 December 2020 to 31 January 2021. RESULT: In Germany and Baden-Württemberg, 1.5% of patients newly infected with SARS-CoV­2 required intensive care treatment in mid-December 2020. With a 7-day incidence of 192 new infections in Germany, the hospitalization rate was 10% and 28-35% of the intensive care beds were occupied by COVID-19 patients. Only 16.8% of the intensive care beds were still available, in contrast to 35% in June 2020. The developed relocation concept has been in use in Baden-Württemberg starting from 10 December 2020. From then until 7 February 2021, a median of 24 ± 5/54 intensive care patients were transferred within the individual clusters, in total 154 intensive care patients. Between the clusters, a minimum of 1 and a maximum of 15 (median 12.5) patients were transferred, 21 intensive care patients were transferred to other federal states and 21 intensive care patients were admitted from these states. The total number of intensive care patients transferred was 261. CONCLUSION: If the number of infections with SARS-CoV­2 increases, a nationwide relocation concept for COVID-19 intensive care patients and non-COVID-19 intensive care patients should be installed at an early stage in order not to overwhelm the capacities of hospitals. Supply regions around a leading clinic with maximum intensive care options are to be defined with a central management that organizes the necessary relocations in cooperation with regional and superregional rescue service control centers. With this concept and the intensive care transports carried out, it was possible to effectively prevent the overload of individual clinics with COVID-19 patients in Baden-Württemberg. Due to that an almost unchanged number of patients requiring regular intensive care could be treated.
