ABSTRACT

OBJECTIVES: Much of the previous research on COVID-19 was based on all population. But substantial numbers of severe episodes occur in older patients. There is a lack of data about COVID-19 in older adults. The aims of this study were to analyze the clinical characteristics of older adult patients with COVID-19.

METHODS: Retrospective study of older patients hospitalized with COVID-19 from February 1 st to March 31 st, 2020 was conducted in the Sino-French New City Branch of Tongjing Hospital in Wuhan, China. According to the degree of severity of COVID-19 during hospitalization, 312 older patients were divided into non-severe and severe cases.

RESULTS: the mean age of the patients was 69.2 ± 7.3 years, and 47.4 % of patients had exposure history. 77.2 % of patients had a co-morbidity, with hypertension being the most common (57.1 %), followed by diabetes (38.8 %) and cardiovascular disease (29.8 %). Multivariable regression showed increasing odds of severe COVID-19 associated with age(OR 1.59, 95 %CI 1.13-2.08), SOFA score(OR 5.89, 95 %CI 3.48-7.96), APACHEⅡ score(OR 3.13, 95 %CI 1.85-5.62), platelet count<125 × 109/L(OR 2.36, 95 %CI 1.03-4.14), d-dimer (OR 4.37, 95 %CI 2.58-7.16), creatinine>133 μmol/L(OR 1.85, 95 %CI 1.12-3.04), interleukin-6(OR 4.32, 95 %CI 2.07-7.13), and lung consolidation(OR 1.94, 95 %CI 1.45-4.27) on admission. The most common complication was acute respiratory distress syndrome (35.6 %), followed by acute cardiac injury (33.0 %) and coagulation disorders (30.8 %). 91.7 % of patients were prescribed antiviral therapy, followed by immune globulin (52.9 %) and systemic glucocorticoids (43.6 %). 21.8 % of patients received invasive ventilation, 1.92 % for extracorporeal membrane oxygenation. The overall mortality was 6.73 %, and mortality of severe patients was 17.1 %, which was higher than non-severe patients (0.962 %).

CONCLUSIONS: Older patients with COVID-19 had much more co-morbidity, complications and mortality. More attention should be paid to older patients with COVID-19.
