The DESs for alcohol, learning disabilities, osteoporosis and ethnicity will be extended into 2010/11.
The GPC said the conclusion of the negotiations meant there would be a year of relative stability in the arrangements for the delivery of services.
Deputy chairman Dr Richard Vautrey said that the committee has been concerned about the near annual change to the GMS contract.
He said it was 'common sense' to allow the clinical DESs to run for another year to enable practices to engage with them.
'The clinical DESs were introduced so late that many practices, even if they wanted to, could not engage with them,' he said. This was particularly the case with the DES for learning disabilities, he added, where practices needed training in place before the service could be provided.
NHS Employers will be publishing an updated version of the clinical DES guidance shortly.
