A look into NHS finances has found a "service under huge pressure", according to one of the report authors.
John Appleby, chief economist at the think-tank, explained:
Our latest quarterly report paints a picture of a service under huge pressure, with cracks beginning to appear in NHS performance.
It once again underlines the need for new funding if services are to be maintained.
The increase in the nursing workforce signals a very welcome commitment to improving care, although it remains to be seen whether hospitals will be able to sustain current staffing levels when money becomes tighter later in the year.
The disparity in the plans of providers and commissioners points to a worrying mismatch between activity and funding, which could have serious financial consequences.
