Diagnostic and Prognostic Prediction Models for Chinese Patients With Venous Thromboembolism

26. november 2019 opdateret af: Ya-Wei Xu

The DOMESTIC Study: Diagnostic and Prognostic Prediction Models for Patients With Venous Thromboembolism in China

The objective of this proposal is to develop and validate diagnostic and prognostic (including short-term and long-term prognoses) prediction models for patients with venous thromboembolism (VTE) in China.

Detaljeret beskrivelse

Venous thromboembolism (VTE), which clinically manifests as deep vein thrombosis (DVT) and pulmonary embolism (PE), is one of the leading causes of mortality that need to be accurately diagnosed and effectively managed. Although a number of clinical decision rules in the domain of VTE have been presented in the literature, such as the well-known prediction models developed by Wells and colleagues, the prognostic models to assess VTE recurrence risk in patients who suffered from a VTE or the Pulmonary Embolism Severity Index (PESI) for short-term mortality risk in PE patients, and various other diagnostic models for both DVT and PE. They are few designed for Chinese patients. The primary objective of this proposal is to develop and validate diagnostic and prognostic (including short-term and long-term prognoses) prediction models for patients with VTE in China.

Studiebefolkning

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:

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.
