How will NHS England monitor the effects of their changes?

Pharmacists and Physios have been working in GP surgeries now for over a year and the aim is to relieve pressure on the GPs so they have time for the more complicated patients. How is the segregation of patients carried out in practice and how are going to measure success?  Reduced spend on medicines? In the past intervention and better compliance often put the cost of medicines up. We hope that the cost of hospital admissions went down thus?   How will the effects of the reduction in pharmacy funding be measured? We know the cost to deliver the service through pharmacy will drop, but will patients go without their medicines, what effect will they have on hospital admissions? Who will be responsible?
