Study Overview
Brief Summary
RE-COVERY is a large, multi-national, multi-center observational study based on new data collection. The study will enroll and characterize patients within 30 days of being diagnosed with an acute DVT and/or PE. The study has two main objectives. Objective 1 will characterize the DVT / PE patient population. All patients with a DVT and/or PE will be enrolled for cross-sectional characterization of the VTE patient population. Objective 2 will compare the safety and effectiveness of dabigatran etexilate regimens for treatment of VTE in comparison to VKA regimens. Patients treated with dabigatran etexilate or VKA will be followed up for the occurrence of outcome events for up to one year.

Primary Outcomes
Objective 1: Anticoagulant Treatment
Time Frame: Baseline collected within 14 days but not more than 6 months after diagnosis of acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
Type of treatment received following acute Venous Thromboembolism (VTE) event of eligible patients collected for Objective 1 during baseline at the time of index event. Aim of Objective 1 was to characterize the Venous Thromboembolism (VTE) patient population including the initial acute event phase, i.e. all patients regardless of treatment. Patients who enrolled in Objective 1 and were treated with VKA or dabigatran were also eligible for Objective 2. The aim of objective 2 was to analyze the safety and effectiveness of dabigatran regimens in the treatment of DVT and PE over 1 year of follow-up in comparison to a VKA regimen. The arm presented in this endpoint was separated into three arms in the participant flow tables ("Not assigned to Dabigatran etexilate or Vitamin K antagonist","Dabigatran etexilate (1)" and "Vitamin K antagonist (1)") in order to distinguish patients participating in both objectives from patients only in objective 2.
Objective 2: Incidence Rate of ISTH (International Society on Thrombosis and Haemostasis) Major Bleeding and CRNMB (Clinically Relevant Non Major Bleeding) Per 100 Patient-years (Pt-yrs)
Time Frame: 12 months following acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
Incidence rate of ISTH (International Society on Thrombosis and Haemostasis) major bleeding and CRNMB (clinically relevant non major bleeding) per 100 patient-years (1/(100\*patient-years)). Each patient in the two treatment groups was weighted proportionally to the probability of that patient being assigned to the opposite treatment group, conditional on relevant observed baseline variables. The propensity scores were estimated using the multivariable logistic regression model. For the restricted patient set, as a sensitivity analysis, the calculation of incidence rates and cumulative risks was performed without censoring at permanent discontinuation.
Objective 2: Symptomatic Recurrent VTE (Venous Thromboembolism) Including VTE Related Mortality
Time Frame: 12 months following acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
Incidence rate of Symptomatic Recurrent VTE (Venous Thromboembolism) including VTE related mortality per 100 patient-years (1/(100\*patient-years)). Each patient in the two treatment groups was weighted proportionally to the probability of that patient being assigned to the opposite treatment group, conditional on relevant observed baseline variables. The propensity scores were estimated using the multivariable logistic regression model. For the restricted patient set, as a sensitivity analysis, the calculation of incidence rates and cumulative risks was performed without censoring at permanent discontinuation.
Objective 1: Sex
Time Frame: Baseline collected within 14 days but not more than 6 months after diagnosis of acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
Sex of eligible patients collected for Objective 1 during baseline at the time of index event. Aim of Objective 1 was to characterize the Venous Thromboembolism (VTE) patient population including the initial acute event phase, i.e. all patients regardless of treatment. Patients who enrolled in Objective 1 and were treated with VKA or dabigatran were also eligible for Objective 2. The aim of objective 2 was to analyze the safety and effectiveness of dabigatran regimens in the treatment of DVT and PE over 1 year of follow-up in comparison to a VKA regimen. The arm presented in this endpoint was separated into three arms in the participant flow tables ("Not assigned to Dabigatran etexilate or Vitamin K antagonist","Dabigatran etexilate (1)" and "Vitamin K antagonist (1)") in order to distinguish patients participating in both objectives from patients only in objective 2.
Objective 1: Index Event
Time Frame: Baseline collected within 14 days but not more than 6 months after diagnosis of acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
Type of index event (e.g., DVT or PE or DVT and PE) diagnosed at the time of acute Venous Thromboembolism (VTE) event of eligible patients collected for Objective 1 during baseline at the time of index event. Aim of Objective 1 was to characterize the Venous Thromboembolism (VTE) patient population including the initial acute event phase, i.e. all patients regardless of treatment. Patients who enrolled in Objective 1 and were treated with VKA or dabigatran were also eligible for Objective 2. The aim of objective 2 was to analyze the safety and effectiveness of dabigatran regimens in the treatment of DVT and PE over 1 year of follow-up in comparison to a VKA regimen. The arm presented in this endpoint was separated into three arms in the participant flow tables ("Not assigned to Dabigatran etexilate or Vitamin K antagonist","Dabigatran etexilate (1)" and "Vitamin K antagonist (1)") in order to distinguish patients participating in both objectives from patients only in objective 2.
Objective 1: Age
Time Frame: Baseline collected within 14 days but not more than 6 months after diagnosis of acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
Age in years of eligible patients collected for Objective 1 during baseline at the time of index event. Aim of Objective 1 was to characterize the Venous Thromboembolism (VTE) patient population including the initial acute event phase, i.e. all patients regardless of treatment. Patients who enrolled in Objective 1 and were treated with VKA or dabigatran were also eligible for Objective 2. The aim of objective 2 was to analyze the safety and effectiveness of dabigatran regimens in the treatment of DVT and PE over 1 year of follow-up in comparison to a VKA regimen. The arm presented in this endpoint was separated into three arms in the participant flow tables ("Not assigned to Dabigatran etexilate or Vitamin K antagonist","Dabigatran etexilate (1)" and "Vitamin K antagonist (1)") in order to distinguish patients participating in both objectives from patients only in objective 2.
