Objective To analyze the clinical characteristics of COVID-19, and provide evidence for its diagnosis and treatment.
Methods Clinical data about 90 patients with COVID-19 admitted to Beijing You'an Hospital confirmed by the Chinese Center for Disease Control and Prevention from January to February in 2020 were analyzed. According to the Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia (trial 6 version) edited by the National Health Committee General Office, the COVID -19 patients were classified into different clinical types, and their clinical features, radiological characteristics and laboratory indicators were observed.
Results Forty-three cases (47%) were male and 47 cases (53%) were female. The age ranged from 1 to 94 years, with average age of (51.7±18.6) years. Mild type was found in 2 cases (2.22%), moderate type in 55 cases (61.11%), severe type in 22 cases (24.44%), and critically ill type in 11 cases (12.22%). The median of incubation period was 3 days (range, 1 to 17 days). The average length of hospital stay was 12.78 days. There were 54 cases (60%) with contact history or travel history to Hubei province, and 58 cases (64.4%) were infected because of gathering. There were statistically significant differences in white blood cell count (WBC), c-reactive protein (CRP), direct bilirubin (DBIL), estimated glomerular filtration rate (eGFR), creatine kinase isoenzyme (CK-MB), myoglobin (MYO), troponin I (TNI) and other parameters between mild/moderate type patients and critically ill patients.
Conclusion The moderate type accounts for a large proportion of COVID -19 patients. Clinical classification is helpful to judge the condition and prognosis more accurately and guide the clinical treatment.
