Link to recent report showing planned move of commissioning to GPs isn't based on international evidence

The report shows that there is little, if any, evidence that smaller
organisations are better at commissioning than larger ones. It also
argues that the transition will be costly, almost certainly resulting in
a dip in performance in the short to medium term.

The report is by the think tank Civitas.

There's an executive summary on page 3. It's also covered in the BMA and
the amusing title with the inneuendo in should hopefully mean more
doctors read it.
