In the first eight years of the incentivisation scheme, 11 indicators were removed (see table 2 and appendix table A1).
For the short term predictions (that is, 2011/12 when the indicator was removed in April 2011), we assumed that indicators were removed in April 2010 and used the method to predict 2010/11, hypothesising that the overall effect would be very close to zero across all models.
For the eighth year (2011/12), a further eight indicators were removed specifically because achievement rates were judged to have reached a ceiling, even though the activities were still deemed to represent best practice.
10 In 2012-13, the QOF underwent a major revision and six clinical indicators were removed from the incentivisation scheme: blood pressure monitoring for coronary heart disease, diabetes, and stroke; cholesterol concentration monitoring for coronary heart disease and diabetes; blood glucose monitoring for diabetes.
