Blood clot prevention

This collaborative aims to improve outcomes and safety for patients who receive medication therapy to prevent blood clot formation.  Called the Michigan Anticoagulation Quality Improvement Initiative (MAQI2), participating physicians, pharmacists and other health professionals review data collected in a comprehensive all-payer clinical registry.

Participants identify best practices and share them with other providers throughout the state. For more information, go to


  • Development and maintenance of the Anticoagulation Toolkit mobile app to help providers manage patients on warfarin more safely and effectively. The app also is a resource for patients seeking information on anticoagulation. The toolkit and mobile app are updated regularly and can be found at
  • Participating sites successfully modified protocols to comply with national guidelines recommending less frequent lab testing for some patients on warfarin. This has resulted in more than 60,000 fewer lab tests performed at MAQI2 sites over the past two years, reducing healthcare costs and patient burden.
  • Participating sites have implemented a process by which adverse events are systematically reviewed to identify root causes and develop prevention strategies. More than 70 adverse events have been reviewed by multi-disciplinary committees resulting in changes to management protocols, staff training, referral processes, and patient education.
