Abstract

Background: The coronavirus disease 2019 (COVID-19) has been rapidly spreading globally since its outbreak in December 2019 at Wuhan, Hubei Province, China. The mortality rate of the older population with COVID-19 is particularly high. Therefore, investigating risk factors related to severe outcomes in older COVID-19 patients is important for effective management of the disease. This study aimed to assess the epidemiological and medical factors in older patients to investigate the risk factors related to the severe outcomes of COVID-19.
Methods: We collected clinical and demographic data and assessed the laboratory parameters, radiologic findings, symptoms, and outcomes of older patients with COVID-19. Among the 248 older patients with COVID-19, of whom 99 had severe COVID-19.
Results: The mortality rate was 6.5%. Older and male patients have more severe COVID-19 outcomes. White blood cell counts and creatine phosphokinase, C-reactive protein, procalcitonin, aspartate transaminase, lactate dehydrogenase, and creatinine levels were higher in the severe outcome group. Age, sex, chest X-ray findings, neutrophil count, C-reactive protein level, lactate dehydrogenase level, and albumin level, total number of symptoms, within-family exposure history, and in-hospital exposure history were associated with severe outcomes in the logistic regression model.
Conclusions: Age, C-reactive protein and lactate dehydrogenase levels, and the total number of symptoms were important risk factors among older patients with COVID-19. Therefore, older patients with these factors require more careful attention and medical care.
