Background: Since April 2020, the number of newly diagnosed cases and death cases of COVID-19 have decreased significantly in China but increased rapidly abroad Early diagnosis and treatment are of great concern to improving the prognosis of COVID-19 patients Objective: To investigate the clinical features and prognostic risk factors of adult patients with COVID-19, offering a reference for clinical diagnosis and treatment of this disease Methods: A retrospective design was used Participants were 93 adult cases of COVID-19 who were treated in Beijing Youan Hospital between January and February 2020 They were categorized into common, severe and critical types by the most serious conditions during hospitalization, in accordance with the Diagnosis and Treatment Protocol for COVID-19(Trial Version 7)issued by the National Health Commission of the People's Republic of China Indications such as general information, major clinical manifestations, baseline laboratory parameters, APACHE II and SOFA scores within 24 hours of admission, imaging findings, comorbidities and complications, treatments and outcomes were collected Results: There were 57 cases of common type(61 3%), 22 of severe type(23 7%)and 14 of critical type(15 0%) The male ratio was slighter higher in critical group, and female ratio was slighter higher in other groups, but sex composition showed no significant differences across the groups(P>0 05) The median age for common, severe and critical groups was 45 0, 62 0 and 81 0 years, respectively, showing significant differences(P0 05) Dyspnea occurred in all severe or critical cases, showing a higher incidence than common cases(100 0% vs 31 6%)(P<0 05) The incidence of lymphocytopenia in critical group was 100%, which was significantly higher than that in common group(49 1%)or severe group(59 1%)(P<0 05) Acute liver injury was the most common complication(58 1%)in all cases, but its incidence was obviously increased in severe group (77 3%) or critical group(92 9%), than that of common group(42 1%)(P<0 05) Chinese medicine therapy was used in 75 3% of all cases, but the severe cases had a higher rate of treating with Chinese medicine than critical cases(90 9% vs 50 0%, P<0 05) The rate of corticosteroid use in severe cases(63 6%)or critical cases(64 3%)was significantly increased than that of common cases(5 3%)(P<0 05) Six patients(6 5%)were treated with invasive ventilation, but only 1 of them(16 7%)was successfully extubated ultimately Nine patients(9 7%)died in hospital due to all causes Logistic regression analysis revealed that age ≥74 years〔OR(95%CI)=33 714(3 021, 376 211), P=0 004〕and baseline SOFA≥2 5〔OR(95%CI)=15 447(1 331, 179 260), P=0 029〕were independent risk factors for in-hospital death Conclusion: COVID-19 mainly manifests as respiratory infections Severe patients are apt to appear tissue injury and dysfunction of organs like liver, kidney and heart, etc The majority of patients have a favorable outcome Age and baseline SOFA score would help to label the prognosis of patients at an early stage Copyright © 2021 by the Chinese General Practice
