Allyson Pollock on the evidence for (or not for) introducing competition:
Several decades of research show that the impact of choice and competition on quality, efficiency and outcomes in healthcare is unproven.
So why all the fuss? Decades of research shows that competition won't make things worse - or rather that we don't know for sure whether it will or not which amounts to the same thing really. I'm willing to take a punt - after all competition works pretty well in other complex service market places!
