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.
