Project #116:
Further analysis of DOAC prescribing for patients with mechanical heart valves

  • Type: Service evaluation
  • Topic areas: Other/indirect impacts of COVID on health/healthcare

During the COVID-19 pandemic, NHS England issued guidance around prescribing of anticoagulants (commonly known as blood thinners); recommending a switch from warfarin to a newer type of anticoagulant, commonly known as DOACs, in some groups of patients. This was partially due to the need for less frequent blood testing in patients prescribed a DOAC. However, DOACs are not recommended for patients with a mechanical heart valve. This study aims to carry on and refine previous work on DOAC prescribing in patients with a mechanical heart valve.
