Can oral anticoagulation be managed using telemedicine and patient self-testing? A pilot study

Area of Science:

• Medical Informatics
• Cardiology
• Health Services Research

Background:

• Oral anticoagulation requires regular monitoring of International Normalized Ratio (INR) levels.
• Traditional anticoagulant management involves frequent clinic visits, posing challenges for patient adherence and healthcare resource allocation.

Purpose of the Study:

• To assess the feasibility and user-friendliness of a telemedicine system for patient self-testing in anticoagulant management.
• To evaluate the TOPCARE (Telematic Homecare Platform in Cooperative Health Care Provider Networks) system for remote INR monitoring.

Main Methods:

• A pilot study involving 23 patients on long-term oral anticoagulation.
• Patients used the TOPCARE system, including a Home Telematic Box (TOPCARE BOX) and CoaguChek S monitor, for weekly INR self-testing.
• Results were transmitted via telephone line to a central, secure database accessed by healthcare professionals.

Main Results:

• Despite early technical challenges with TOPCARE BOX functionality and database access, patients successfully transmitted 222 INR results over five months.
• Four patients dropped out; nine of 19 distributed TOPCARE BOXs were fully functional initially.
• Patient and staff feedback indicated the system was user-friendly, though technical issues necessitated thorough pre-installation testing.

Conclusions:

• Telemedicine, utilizing systems like TOPCARE, presents a feasible approach for managing oral anticoagulation therapy.
• Further technological refinement and rigorous testing are crucial for successful widespread implementation of such remote patient monitoring systems.
