What are the changes needed now to ensure the NHS is sustainable in the future?

The NHS is facing one of the biggest crises in its history. With an ageing population, the increasing cost of drugs and treatments, and lack of funding for social care, the service is under more pressure than ever and the cracks are already starting to show. So will the system be able to cope in future as the UK's population gets older - and can the NHS survive?

David Aaronovitch hears from expert witnesses including Dame Julie Moore, Chief Executive of University Hospital Birmingham NHS Foundation Trust and John Appleby, Chief Economist at the Nuffield Trust.
