Title: Risk factors for disease severity, unimprovement, and mortality of COVID-19 patients in Wuhan, China Cord-id: 2dje7ts9 Document date: 2020_4_15
ID: 2dje7ts9
Snippet: OBJECTIVE: Since December 2019, coronavirus disease (COVID-19) emerged in Wuhan. However, the characteristics and risk factors associated with disease severity, unimprovement and mortality are unclear. METHODS: All consecutive patients diagnosed with COVID-19 admitted to the Renmin Hospital of Wuhan University from January 11 to February 6, 2020 were enrolled in this retrospective cohort study. RESULTS: A total of 663 COVID-19 patients were included in this study. Among those, 247 (37.3%) had at
Document: OBJECTIVE: Since December 2019, coronavirus disease (COVID-19) emerged in Wuhan. However, the characteristics and risk factors associated with disease severity, unimprovement and mortality are unclear. METHODS: All consecutive patients diagnosed with COVID-19 admitted to the Renmin Hospital of Wuhan University from January 11 to February 6, 2020 were enrolled in this retrospective cohort study. RESULTS: A total of 663 COVID-19 patients were included in this study. Among those, 247 (37.3%) had at least one kind of chronic disease. A total of 0.5% (n=3) of patients were diagnosed with mild COVID-19, while 37.8% (251/663), 47.5% (315/663), and 14.2% (94/663) were in moderate, severe, and critical condition, respectively. In our hospital during follow-up, 251 of 663 (37.9%) patients were improved and 25 patients died, leading to a mortality rate of 3.77%. Older patients (>60 years old) and those with chronic diseases were prone to have severe and critical COVID-19 conditions, show unimprovement, and die (P < 0.001, < 0.001). Multivariate logistic regression analysis identified being male (OR = 0.486, 95% CI 0.311-0.758; P = 0.001), having severe COVID-19 conditions (OR = 0.129, 95% CI 0.082-0.201; P < 0.001), expectoration (OR = 1.796, 95% CI 1.062-3.036; P = 0.029), muscle ache (OR = 0.309, 95% CI 0.153-0.626; P = 0.001), and decreased albumin (OR = 1.929, 95% CI 1.199-3.104; P = 0.007) were associated with unimprovement in COVID-19 patients. CONCLUSION: Being male, in severe COVID-19 conditions, expectoration, muscle ache, and decreased albumin were independent risk factors which influence the improvement of COVID-19 patients.
