It is not always possible for GP practices to achieve all the points available in QOF. Therefore, NHS Digital produces a further measure of GP practice achievement. This measure takes account of instances where GP practices cannot achieve points because they have no patients relevant to an indicator and can be found in the achievement tables at GP practice level.
For example: if in a given financial year there are 559 QOF points available and 45 of these points are for asthma indicators but the GP practice does not have patients on their asthma register (no patients meeting the established criteria), then it would not be possible to achieve any of the points allocated to the asthma indicators.
Therefore, even if the GP practice achieved all other points available they would only be able to attain 91.9% overall achievement (points achieved / points available) * 100.
In these circumstances, the standard ‘points achievement’ measure may not be representative and may result in a GP practice’s achievement apparently declining from one year to the next where they have patients on a register in one year but none in the next year.
To represent GP practice points achievement more fairly, NHS Digital calculates adjusted maximum points achievable for each GP practice, effectively removing points from the calculation denominator where both of the following conditions apply:
- the GP practice does not have any patients in the indicator denominator
- the GP practice has reported no PCAs for the indicator denominator
The indicator denominator plus indicator PCAs must equal zero. This ensures adjustment of maximum points achievable where there are patients on the relevant disease register (PCAs are included in the disease register, but not in the relevant denominator), who have not received the interventions.
For example: if in a given financial year there are 559 QOF points available and 45 of these points are for asthma indicators but the GP practice does not have patients on their asthma register then points available would be QOF points available minus the ‘unachievable’ asthma points.
In this case, the difference between the GP practice’s ‘points achievement’ and ‘points achieved as a percentage of QOF points available’ would be as follows:
Points achievement = (Points achieved / All QOF points) * 100
91.9% = (514 / 559) * 100
Points achieved as percentage of QOF points available = (Points achieved / QOF points available) * 100
100% = (514 / 514) * 100
'Points achieved as a percentage of QOF points available’ figures are calculated for overall achievement and can be found in the achievement tables.
