Professor Bernard Crump, chief executive of the NHS Institute for Innovation and Improvement, was speaking at a Health Select Committee session on value for money in the NHS on Thursday.
Witnesses were quizzed on whether the new GP and consultant contracts had improved productivity.
Professor Crump said this had not happened, but it had never been the principle intention.
‘Productivity has not improved but the focus on important aspects of primary care has improved by all measures,' he said of the GP contract.
Professor Clump put the success largely down to QOF.
‘History will say that the implementation of the QOF was one of the best international examples of a paid-for-performance framework in getting clinical attention to focus on important issues,' said Professor Crump.
