A couple of weeks ago the BMA issued its guidance on the QOF changes for this year. Basically some organisational areas were cut and the points transferred to two new areas to be based on surveys of patients.
The survey questions seem likely to be very similar, if not identical, to those asked about appointment booking in the 2007 patient survey.
As we have some data to go on, for England at least, the effect of the changes can be modelled at practice level. In fact I have done this for all practices in the UK, simply the results are likely to be less reliable outside England. In particular the square rooting of the COPD prevalence is based on the English average - slightly overestimating losses outside England.
To find the data for individual practices just use the search or browse pages to find the practice and then select from the menu on the left side.
