Abstract
Purpose: The primary aim of this study was to assess the outcome of elderly ICU patients treated during the spring and autumn COVID-19 surges in Europe.Methods: A prospective European observation study (The COVIP study) in ICU patients aged 70 years and older admitted with COVID-19 disease from March to December 2020. An electronic Case Record Form was used to register a number of parameters including: SOFA score, Clinical Frailty Scale, comorbidities, usual ICU procedures including pharmacotherapy, limitation of care, ICU length of stay and survival at 30 days. The study was registered at ClinicalTrials.gov (ID: NCT04321265).Results: In total 2711 patients were included, 1325 from the first and 1291 from the second surge and 94 in between. Median age was 74 and 75 years in surge 1 and surge 2 respectively. SOFA score was higher in the first surge (median 6 versus 5, p2/FiO2 ratio at admission was higher during surge 1 and more patients received mechanical ventilation (78% versus 68%, pConclusion: An unexpected, but significant, increase in 30-day mortality was observed during the second surge in our cohort of elderly ICU patients. The reason for this is unknown, however, practice changed and this might not be supported by sufficient evidence in this elderly population with COVID-19.Trial Registration: NCT04321265Funding Statement: The support of the study in France by a grant from Fondation Assistance Publique-Hôpitaux de Paris pour la recherche is greatly appreciated. In Norway, the study was supported by a grant from the Health Region West. In addition, the study was supported by a grant from the European Open Science Cloud (EOSC). EOSCsecretariat.eu has received funding from the European Union's Horizon Programme call H2020-INFRAEOSC-05-2018-2019, grant agreement number 831644.Declaration of Interests: The authors declare that they have no competing interests.

The money went into departmental funds. No personal financial gain applied.Ethics Approval Statement: The study was organised by the Very old Intensive care Patients (VIP) project 10,11 within the European Society of Intensive Care Medicine (ESICM) who also endorsed the study (www.vipstudy.org). Due to variations in requirement for ethical consent, some countries could recruit patients without upfront informed consent while others had to obtain it. The study deliberately allowed for coenrolment of study patients to other COVID-19 studies. The study adhered to the European Union General Data Privacy Regulation (GDPR) directive.
Highlights
The first surge of the COVID-19 pandemic between March and May 2020 affected the elderly population disproportionally
4/1327 patients were lost to follow-up and in the second surge, 25/1298 patients were lost to follow-up
P aO2/FiO2 ratio and sequential organ-failure assessment (SOFA) score were lower in patients during the second surge of the pandemic and there was an increased prevalence of diabetes mellitus and ischemic heart disease
Summary
The first surge of the COVID-19 pandemic between March and May 2020 affected the elderly population disproportionally. In addition to established and new disease severity scores, geriatric characteristics notably frailty, co-morbidity and functional status were soon confirmed to be important prognostic factors in elderly COVID-19 patients [3,4,5,6]. Clinical studies were quickly launched focusing on potential novel treatments and the management of patients with COVID-19. These included respiratory management, such as the role of mechanical ventilation and prone positioning as well as pharmacological treatment (e.g. corticosteroids, anticoagulation and anti-inflammatory agents) [7, 8]. The primary aim of this study was to assess the outcome of elderly intensive care unit (ICU) patients treated during the spring and autumn COVID-19 surges in Europe
