It said PCTs that have not decided the future options for their community provider arms will not be able to complete the transfer in six months time.
It warned that PCTs may be making decisions to fit the tight timetable, rather than making the right decision.
Meanwhile, the NHS Confederation also warned that transferring services without the accompanying transformation is a waste of time, effort and ‘considerable resources’.
David Stout, director of the NHS Confederation’s PCT Network, said: ‘We must not forget that in the midst of these changes NHS organisations still need to make significant savings.
‘These services must be able to truly transform the way patients receive care while at the same time doing more for less money. If this is not achieved on a broad scale, all we will have will be another expensive reorganisation of services.’
