Point-of-Care Testing (POCT) for Guided Precision Anticoagulation With Warfarin: A Multicenter, Non-concurrent Controlled Study

October 14, 2024 updated by: RenJi Hospital
This study aims to compare the key clinical indicators such as the time to achieve INR target, frequency of dose adjustment, and the incidence of thrombotic and hemorrhagic events between Point-of-Care Testing (POCT) and pyrosequencing technology in the precision dosing of warfarin, in order to assess whether POCT-based warfarin genetic testing is beneficial for improving the quality of anticoagulation treatment for patients.

Arms and Interventions

Participant Group / Arm

Experimental: POCT group
Patients undergo POCT testing on the day of warfarin administration, and based on the POCT results, the initial and maintenance doses of warfarin are determined according to the IWPC algorithm.
No Intervention: pyrosequencing group
