Overview

Multicenter study validates Bluetooth POC device for accurate INR monitoring in warfarin management, indicating improved patient outcomes.

Key Points

  • The aim is to validate a Bluetooth-enabled point-of-care INR device for effective warfarin management.
  • Conducted a multicenter study comparing two POC INR devices to an internal plasma INR reference.
  • Evaluated appropriateness of dosing decisions made based on device readings.
  • Included warfarin-treated patients at three Mayo Clinic sites.
  • CoaguChek devices showed 86.1% of values within 0.4 INR units of plasma INR reference.
  • High correlation between CoaguChek and Vantus devices with plasma INR values.
  • Common indications for warfarin included atrial fibrillation and venous thromboembolism.
