Point-of-care testing INR: an overview

Area of Science:

• Pharmacology and Thrombosis Management
• Medical Technology and Telehealth

Background:

• Oral anticoagulant therapies (AVK) like warfarin require regular International Normalized Ratio (INR) monitoring.
• Traditional INR monitoring causes patient discomfort and requires frequent clinic visits.
• Venous thromboembolism, atrial fibrillation, and mechanical heart valves are common indications for AVK.

Purpose of the Study:

• To evaluate the advantages and disadvantages of using point-of-care testing (POCT) for AVK monitoring.
• To examine the impact of POCT on therapy quality, safety, and cost-effectiveness.

Main Methods:

• Overview of POCT devices for self-testing of INR.
• Description of telemedicine and telecare models integrating POCT with thrombosis centers (TC).
• Analysis of clinical outcomes, safety events, and 10-year cost-effectiveness.

Main Results:

• Telemedicine-assisted POCT management is equally or more effective than traditional AVK monitoring regarding thrombotic and hemorrhagic events.
• Self-testing and self-management using POCT are cost-effective over a 10-year period.
• POCT enables decentralized monitoring, improving patient convenience and potentially therapy quality.

Conclusions:

• POCT represents a viable and beneficial alternative for monitoring oral anticoagulant therapies.
• Decentralized monitoring via POCT enhances patient care, safety, and cost-efficiency.
• Further examination of POCT's role in AVK management is warranted.
