Atrial Fibrillation
Registration Number
NCT05361889
Lead Sponsor
Henan Provincial People's Hospital
Brief Summary

Anticoagulation therapy is the most important part of the treatment strategy for atrial fibrillation. Previous studies have confirmed that both warfarin and new oral anticoagulants can effectively prevent stroke in patients with atrial fibrillation. However, the current situation of anticoagulation in atrial fibrillation is not optimistic. This project aims to explore the prevalence of inappropriate doses of anticoagulants in my country. , and the influencing factors related to such doses. By analyzing the status quo, characteristics and influencing factors, suggestions and management plans to promote rational use are put forward to provide certain guidance and help for anticoagulation therapy in patients with atrial fibrillation.

Detailed Description

The project is carried out in 30 research centers across the country, and the research object is the prescription/medical order data of real-world atrial fibrillation patients (outpatient and inpatient), including clinical diagnosis, drug use, outpatient and emergency and inpatient records, medical records, as well as laboratory tests, Demographic and other aspects of information, a total of 5000 patients were included, and it is expected to be completed within 3 years. The analysis indicators include patient population distribution, comorbid diseases, concomitant drugs, creatinine clearance rate, proportion of various drugs used, CHA2DS2-VASc score and embolism risk, HAS-BLED score, antithrombotic therapy, etc., to evaluate the influencing factors of inappropriate anticoagulation dose, and to explore the macro trend of anticoagulation therapy.

Primary Outcome Measures
NameTimeMethod
Number of major bleeding events3 years

Major bleeding will be defined according to International Society of Thrombosis and Hemostasis (ISTH) criteria.

Prevalence of potentially inappropriate NOAC prescriptions3 years

We will adopt an adaptive design to involve for summary of products characteristics, and perform appropriateness assessments of prevalent NOAC strategies based on indications, NOAC selection, or dosages according to reference materials from approved NMPA labeling recommendations for each agent and 2021 European Heart Rhythm Association (EHRA) Practical Guide on the Use of NOACs in AF Patients.

Patient profiles with NOAC prescriptions3 years

Identify the characteristics of participants who were given appropriate NOAC prescriptions and those who did not from various perspectives: demographics, clinical, medical management, prescription information, therapy, regional differences, types of treating physicians, and NOACs availability.

Secondary Outcome Measures
NameTimeMethod
Adverse events3 years

Detailed data on management of NOAC-related adverse events will be collected.
