VTE and the Related Factors Associated With Higher Rates of PE After a DVT in Southwestern China

Little is known about the current management status of venous thromboembolism (VTE) in Southwestern China. We aimed to investigate the status of anticoagulant administration in VTE in Southwestern China and assess the potential predictors of deep vein thrombosis (DVT) complicated pulmonary embolism (PE). We extracted data from YiduCloud database from December 2006 to November 2018 and performed a cross-sectional survey of VTE. The demographics, laboratory tests, and anticoagulants were collected and analyzed in the logistic regression model, classification tree and Random Forest model.

About this study

We established a collaborative epidemiological work of southwestern China for our cross-sectional survey sample, which included hospitalized patients in the seven main medical centers who met the inclusion criteria. The Human Research Committee of Chongqing Medical University approved this study and waived the need for informed consent. Patients were eligible to be included in the study if they are admitted or discharged with a diagnosis of DVT or/and PE and if they ever received treatment in the seven medical centers between December 2006 to November 2018.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

In the Chinese VTE guidelines, the diagnosis of VTE depends on a series of tests. D-dimer was used to screen for thrombosis, and limb venous ultrasound was used to diagnose DVT. CT pulmonary angiography (CTPA) or pulmonary ventilation perfusion scan was used for the diagnosis of pulmonary embolism. Through the retrieval of patient diagnosis in the database, we retrieved the basic data of all patients diagnosed as VTE during the study period.
