AF008 - AF on a DOAC

Warning
The codes referenced in this article are taken from the NHS Technology Reference Update Distribution (TRUD).  Not all of these may be present or selectable in all clinical systems.
Info
The information contained within this article is from version 50 of the Business Rules for Quality and Outcomes Framework (QOF).                                                                                  
Idea
This indicator was updated in version 50 for the contract year 2025/26 to add the ability to use two invites to remove the patient from the indicator                                                    

Indicator definition

Indicator ID

Description

AF008

Percentage of patients on the QOF Atrial Fibrillation register and with a CHA2DS2-VASc score of 2 or more, who were prescribed a direct-acting oral anticoagulant (DOAC), or, where a DOAC was declined or clinically unsuitable, a Vitamin K antagonist.

What do the business rules mean?

What makes a patient eligible?

Patients are eligible for the AF008 denominator if:
  1. they are on the Atrial Fibrillation (AF) register.
  2. their most recent CHA2DS2-VASc stroke risk assessment scored 2 or more or patient did not have a CHA2DS2-VASc but their most recent CVD risk assessment was a CHADS2 stroke risk assessment score of 2 or more recorded prior to April 2015.

What must I do to achieve the indicator

Patients will achieve the indicator if:
  1. They have no record of a mechanical prosthetic valve replacement and were prescribed a direct-acting oral anticoagulant (DOAC) in the 6 months up to and including the reporting period end date

  2. Have no record of a mechanical prosthetic valve replacement, were prescribed a Vitamin K antagonist (warfarin) in the 6 months up to and including the reporting period end date and have any of the following criteria:

    1. Have chosen not to receive a direct-acting oral anticoagulant (DOAC) in the contract year

    2. Have a direct-acting oral anticoagulant (DOAC) contraindication code anywhere in their record.

    3. Have an Antiphospholipid syndrome diagnosis anywhere in their record.

    4. Have a direct-acting oral anticoagulant (DOAC) not indicated code in the contract year AND whose last recording of 'Time in Therapeutic Range (TTR)’ was greater than or equal to 65% and recorded in the last 6 months of the contract year.

  3. Have a mechanical prosthetic valve replacement and were prescribed a Vitamin K antagonist in the last 6 months of the contract year.

What will remove patients from eligibility?

  1. Patients who have a mechanical prosthetic valve replacement with no oral anticoagulant issued and either:

    1. a Vitamin K antagonist contraindication code anywhere in their record

    2. have chosen not to receive a Vitamin K antagonist in the contract year

  1. Patients who have no record of a mechanical prosthetic valve replacement replacement as well as a Vitamin K antagonist contraindication code anywhere in their record OR chosen not to receive a Vitamin K antagonist in the contract year as well as one of the following:

      1. a direct-acting oral anticoagulant (DOAC) contraindication code anywhere in their record

      2. a diagnosis of Antiphospholipid syndrome anywhere in their record

      3. a direct-acting oral anticoagulant (DOAC) not indicated code in the contract year

  1. Patients who have no record of a mechanical prosthetic valve replacement AND BOTH OF THE BELOW:

    1. have chosen not to receive a direct-acting oral anticoagulant (DOAC) in the 12 months up to and including the reporting period end date 

    2. have a Vitamin K antagonist (warfarin) contraindication code anywhere in their record or have chosen not to receive a Vitamin K antagonist in the contract year
  1. Patients who have a persisting generic oral anticoagulant contraindication code recorded 
  2. Patients who have an expiring generic oral anticoagulant contraindication code recorded within with contract year
  3. Patients who declined oral anticoagulant medication in the contract year
  4. Patients who have not responded to two invitations for a review at least 7 days apart in the contract year
  5. Patients who were diagnosed with AF in the last 3 months of the contract year
  6. Patients who were newly registered with the practice in the last 3 months of the contract year

Notes
If a patient achieves the indicator at any point during the year, any exclusions that have also been added are ignored.
