Worst case scenario
In the Health Service Journal in July, management consultant Chris Robson, who works with NHS trusts on purchasing, predicted the cost could be up to £900m.
When we talk this month, he says things have not changed much, around a billion pounds per year, he says.
But he is keen to stress that is a “worst case scenario” and highly dependent on long-term currency movements.
He hopes the actual figure will not be anything near that and he says much can be done to avoid this cost; there are large savings and efficiencies to be made – but there might also be quite a lot of “running to stay still”.
