Professor Michael McMahon:

I will give a general answer. We have called on many occasions recently for a form of spending review or evaluation to take place as a useful exercise. It should not only happen once a decade or every 20 years but on a relatively regular basis. It is natural that the budgetary process focuses on increments and new things but every so often, it makes sense to ask where we are, as a society, and where we think spending should be focused. Health is no different.
