INR at Home Measurement by the LabPad® Point-of-care in Patients on Vitamin K Antagonist Drugs (VKA)

Medicalps128 enrolled

Overview

This study evaluates the impact of using LabPad® point-of-care to measure International Normalized Ratio (INR) at home on the patient's follow up on vitamine K antagonist (VKA) treatment during 6 months.

The impact of the LabPad® point-of-care use by the nurse will be evaluated in the patients on vitamine K antagonist (VKA) treatment by measuring the time elapsed between the reading of the International Normalized Ratio (INR) by the LabPad® at patient's home and the validation of the biological measure, The time that the patient spends in his therapeutic range will be measured. The adverse events related to VKA will also be collected. At the end of the study, the patient will complete satisfaction and usage questionnaires about the LabPad®. This study will be performed for 6 months.
