An Early Warning Model for Assessing the Onset, Progression and Sequelae of COVID-19

Study Overview
=================
Brief Summary
-----------------
Based on the characteristics of symptoms, differences in physical and chemical examinations and tests, and characteristics of traditional Chinese medicine (TCM) disease differentiation and syndrome differentiation, the evaluation indicators for the clinical early warning model were screened, and the three-level early warning mechanism for COVID-19 patients at high risks, with progression to severe cases and sequelae was constructed.

Detailed Description
-----------------
Adopt multi-level evidence base architecture, build multi-source data analysis, feature extraction, multi-level evidence extraction, active The integrated Chinese and Western medicine big data platform integrates the original evidence processing into a multi-level evidence base, comprehensive analysis of The platform will generate a multi-level evidence base by processing the original evidence, analyze the evaluation indexes of New Coronary Pneumonia, select the features, build a deep neural network model, train and validate the model, and establish a high The model is trained and validated, and a three-level early warning model is established for people at high risk of new coronary pneumonia, those who turn serious, and those with sequelae.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| General Data: | including age, underlying diseases, body weight, occupation, smoking, alcohol drinking, salt intake and exercise | Not more than 5 days after the occurrence of the first symptom (or confirmed onset) | 
| Environment Indicators: | air temperature, humidity, and air quality | Not more than 5 days after the occurrence of the first symptom (or confirmed onset) | 
| Auxiliary Examination Indicators: | blood routine (lymphocyte count, lymphocyte/neutrophil ratio), four coagulation items (PT, APTT, TT, FIB), D-Di, C-reactive protein, erythrocyte sedimentation rate, liver function (ALT, AST, ALP), renal function (BUN, Cr), blood glucose, lung CT | Not more than 5 days after the occurrence of the first symptom (or confirmed onset) | 
| TCM based Evaluation: | TCM constitution differentiation With reference to the Classification and Determination of Constitutions in TCM issued by the China Association of Traditional Chinese Medicine. There are nine constitution types based on TCM syndrome differentiation | Not more than 5 days after the occurrence of the first symptom (or confirmed onset) |
