It is important that you check that QOF disease registers are accurate (in terms of patient population) before 31st March, and I would recommend completing this work before 1st January so that you have time to maximise QOF point achievement.
QOF income is list-size and prevalence weighted. This means that QOF income not only depends on QOF points achieved, but also the number of patients on each QOF register. In fact it is possible to work out the exact amount of income you can generate per patient for each QOF domain and I have attached a document to this post which contains this information for 2021/22.
Ardens Resources to Improve Prevalence
The search folder "5.0 Ardens Case Finders" can be used to identify coding errors affecting reported chronic disease prevalence in individual GP practices. We have produced detailed instructions (www.ardens.live/case-finders) that explain how to use these searches and I recommend that you read these before undertaking any re-coding work.

Case Finder data can be uploaded to Ardens Manager in areas subscribing to the National Contract Dashboards to help monitor and track improvement in data quality.
Technical Explanation (for those that are interested)
How is prevalence linked to QOF income?
QOF income in any financial year is calculated using 3 variables:
- QOF points achieved - The value of a QOF point for 2021/22 is £201.16.
- Contractor Population Index (CPI) - this is your practice list size divided by the "national average list-size" which changes annually (for 2021/22 it is 9,085 patients).
For example if your list size is 16,000 patients then your CPI is 16,000 / 9,085 = 1.76.
- Adjusted Practice Disease Factor (APDF) - this is your practice disease prevalence for a particular chronic disease divided by the national average disease prevalence. You can view your practice data from last year using NHS Digital's online database (although I find www.gpcontract.co.uk easier to use).
For example the national average prevalence of AF for 2020/21 is 2.03%. If your practice prevalence is 3.05% then your APDF for AF will be 3.05/2.03 = 1.50.
All 3 of the above variables influence what payment is made for each QOF domain:
QOF income = Points Achieved x £201.16 x CPI x APDF
So, using the above AF example in a 16,000 patient practice with all 29 points achieved:
QOF income for AF = 29 x £201.16 x 1.76 x 1.50 = £15,400
Please note that no-one has access to 2021/22 prevalence data as it is not extracted until March 31st 2022. The above calculations will therefore only be approximate as we have to use 2020/21 national prevalence data.
