In the first of a monthly series of columns for GP's Commissioning section, Paul Corrigan says that GPs and PCTs think about the world in 'very different' ways.
PCT managers deal in 'large scale, with not as much attention to detail', whereas GPs look after smaller organisations and want to tackle service changes 'with speed and attention to detail'.
Mr Corrigan goes on to warn that GPs are unlikely to be motivated to engage with commissioning if they feel the only way to do so is to become involved in 'something of a population base of half a million'.
Commissioning lessons learned by PCTs may not be entirely transferrable to GP consortia as a result of this cultural difference, he warns, and consortia will need to be built from the ground up.
Starting with the big picture approach will not enthuse GPs, he warns.
