Conditions

Venous Thromboembolism Pulmonary Embolism Deep Vein Thrombosis Venous Thromboses

Summary

After hip or knee replacement all patients receive a standardized treatment with blood thinners, this medication is called thrombosis prophylaxis. However, despite this standard treatment some individuals still develop venous thrombosis (VTE), while others experience bleeding. This indicates that not all patients have the same VTE risk following surgery. Individualizing the amount of thrombosis prophylaxis following surgery might lead to less thrombotic and bleeding events. In this study the investigators individualize the treatment with thrombosis prophylaxis based on the medical history of a patient. The main questions this study aims to answer are: Can thrombosis prophylaxis be shortened in patients with a low VTE risk to decrease the risk of bleeding without increasing the risk of VTE? Does an increase in the dose and duration of thrombosis prophylaxis in patients with a high VTE risk reduce the risk of VTE without inducing an unacceptable risk of bleeds? Researchers will compare both the shortened treatment in low VTE risk patients and the intensified and extended treatment in high VTE risk patients with the standard treatment to assess the risk of VTE and bleeding in comparison to the standard treatment. Participants will receive 4 questionnaires to evaluate whether they have experienced a VTE or bleed. For this study no additional hospital visits are necessary.

Interventions

OTHERShort duration prophylaxis

Only during hospitalization: any type of LMWH or DOAC in a prophylactic dose as approved by the Dutch guideline "Antitrombotisch beleid". First dose of LMWH within 6-24h following surgery. First dose of apixaban within 12-24h following surgery. First dose of rivaroxaban 6-10h following surgery. First dose of dabigatran within 1-4h following surgery. The applied type of anticoagulant is according to the local standard use (same type as used for control group).

OTHERHigher intensity and longer duration prophylaxis

The use of any thrombocyte aggregation inhibitors should be discontinued 5 days prior to surgery. Day 0-2: any type of LMWH or DOAC in a prophylactic dose as approved by the Dutch guidelines. First dose of LMWH within 6-24h following surgery. First dose of apixaban within 12-24h following surgery. First dose of rivaroxaban 6-10h following surgery. First dose of dabigatran within 1-4h following surgery. The applied type of anticoagulant is according to the local standard use. Day 3: Apixaban 5mg b.i.d., continued until 6 weeks after surgery, conditional on the fact that no active bleeding of the surgical wound can be observed. In case of active bleeding, the prophylactic dose of thrombosis prophylaxis is continued. Thereafter, in case no active bleeding has been observed for 24 hours, the 5mg b.i.d. apixaban treatment will be started. The 5mg b.i.d. apixaban dose will be adjusted to 2.5mg b.i.d. in case of an impaired kidney function (defined as eGFR 10-30ml/min).

OTHERControl

4 weeks: any type of LMWH or DOAC in a prophylactic dose as approved by the Dutch guidelines. First dose of LMWH within 6-24h following surgery. First dose of apixaban within 12-24h following surgery. First dose of rivaroxaban 6-10h following surgery. First dose of dabigatran within 1-4h following surgery. The applied type of anticoagulant is according to the local standard use.
