Comparison of the outcomes of warfarin therapy and economics by online and offline anticoagulation management models: protocol for a randomised controlled trial.

ABSTRACT

INTRODUCTION: Warfarin is widely used in the world as oral anticoagulant, but it is difficult to manage patients after medication due to its narrow treatment window and individualised differences. Therefore, every region uses network means to carry out online anticoagulant therapy services. The purpose of this paper is to compare monitoring results and randomised controlled studies of the complications of warfarin treated by offline or online management in a Chinese population. METHODS AND ANALYSIS: This is a randomised controlled, multicentre clinical trial. Taking the Union Hospital Affiliated to Fujian Medical University as the main centre, a randomised controlled study of several subcentres around China produced a nationally representative sample. 496 participants who took warfarin will be recruited and then randomly divided into two groups at a ratio of 11. We will collect data on patient characteristics, diagnosis, treatment, hospitalisation results and later complications. ETHICS AND DISSEMINATION The study was approved by the Ethics Committee of the Union Hospital Affiliated to Fujian Medical University. All cooperative hospitals have been approved by the Central Ethics Committee. The results of the survey will be disseminated in future peer review documents and will provide the basis for a management model for patients in China taking warfarin.
