Abstract
Introduction: There is limited information on elderly patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infections. We aimed to describe the characteristics and outcomes of elderly patients with Omicron variant infections admitted to the intensive care unit (ICU) on the Chinese mainland and to evaluate the risk factors associated with mortality in these patients.
Methods: We conducted a multicenter retrospective study including elderly patients with SARS-CoV-2 infection who were admitted to the ICU from November 1, 2022, to February 11, 2023, on the Chinese mainland. The primary objective of the study was to describe the characteristics and outcomes of elderly ICU patients with Omicron variant infections. The secondary objective was to evaluate the risk factors for mortality of these patients.
Results: We included 1,605 patients aged 65 years or older diagnosed with severe or critical COVID-19 and admitted to ICUs in 59 hospitals across different areas of the Chinese mainland. The median age was 78 years (P25-P75, 72-84), with male patients accounting for 1,164/1,605 (72.5%) and 1,459/1,605 (90.9%) of patients having at least one comorbidity. The median APACHE II scores and SOFA scores were 16 (P25-P75, 11-23) and 5 (P25-P75, 3-8), respectively. Among these patients, 553 (34.5%) were recovery discharged, 557 (34.7%) died in the ICUs, and 495 (30.8%) discharged voluntarily during therapy and were later confirmed dead after discharge. Multivariable logistics analysis indicated that older age, coinfection, high levels of white blood cell count, blood urea nitrogen, D-dimer, and lactate at admission were against for recovery discharged.
Conclusions: Elderly patients infected with the Omicron variant of SARS-CoV-2 and admitted to the ICU had a considerable mortality rate. Better understanding of risk factors for mortality may improve clinical management and more rational allocation of limited medical resources during a COVID-19 surge.
期刊介绍:
In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
