United Health Group CEO Simon Stevens was one of the key influencers of the NHS reforms of the past decade.
His formidable intelligence and strong communication skills made him an iconic figure in health policy over the period 2000-10, despite his leaving for the USA mid-way through the decade.
Perhaps a significant part of this was his long-standing interest in the commissioning function. The NHS's problem at the start of the decade was one of under-capacity in provision. As such, the National Hospital Service devoured the majority of the available attention and resource.
