Great Ormond Street Hospital for Children has deferred its foundation trust application because of continuing uncertainty over the payment by results tariff for specialist services.

Great Ormond Street Hospital for Children has deferred its foundation trust application because of continuing uncertainty over the payment by results tariff for specialist services.

Chief executive Dr Jane Collins said the government had not yet addressed the concerns of children?s trusts about the principles of PbR.

Dr Collins also criticised proposed changes to NHS research funding and the way the new private patient cap affected the trust?s income by barring it from treating as many international patients.

'The financial issues still remain too unclear for a responsible five-year plan,' she said.

In April, Dr Collins, and the chairs and chief executives of three other children's trusts, wrote to health minister Lord Warner and acting NHS chief executive Sir Ian Carruthers claiming that miscalculations in the tariff left them facing a£22m shortfall.
