Study Arms (2)

Derivation Cohort

Derivation Cohort of Diagnostic Prediction Model: Participants will be recruited from the emergency department of five general urban hospitals in China, including Shanghai Tenth People's Hospital; Nanfang Hospital of Southern Medical University; First Affiliated Hospital, Sun Yat-Sen University; Zhongshan Hospital Xuhui Branch, Fudan University; Shanghai Baoshan Luo Dian Hospital; from March 1, 2019. The investigators will randomly assign 70% participants to a derivation cohort. Derivation Cohort of Prognostic Prediction Model: Patients with VTE from 5 thrombosis centers in China, including Shanghai Tenth People's Hospital; Nanfang Hospital of Southern Medical University; First Affiliated Hospital, Sun Yat-Sen University; Zhongshan Hospital Xuhui Branch, Fudan University; Shanghai Baoshan Luo Dian Hospital; between January 2014 and December 2018.

Validation Cohort

Validation Cohort of Diagnostic Prediction Model: The investigators plan to randomly assign 30% participants for developing the diagnostic prediction model to a Validation cohort. Validation Cohort of Prognostic Prediction Model: New individuals selected by the same inclusion and exclusion criteria as the derivation cohort of prognostic prediction model from the same institutions as a validation cohort of prognostic prediction model will be recruited from January 2019.

Development and validation of diagnostic prediction model: Participants will undergo recruitment from the emergency department of five general urban hospitals in China, including Shanghai Tenth People's Hospital; Nanfang Hospital of Southern Medical University; First Affiliated Hospital, Sun Yat-Sen University; Zhongshan Hospital Xuhui Branch, Fudan University; Shanghai Baoshan Luo Dian Hospital; from March 1, 2019. Development and validation of prognostic prediction model: The investigators will identify patients with VTE from 5 thrombosis centers in China, including Shanghai Tenth People's Hospital; Nanfang Hospital of Southern Medical University; First Affiliated Hospital, Sun Yat-Sen University; Zhongshan Hospital Xuhui Branch, Fudan University; Shanghai Baoshan Luo Dian Hospital; between January 2014 and December 2018 using the Hospital Information Manage System(HIMS) database.
