As has been discussed before CPCS is a mixed bag. For some, it's been an effective tool for having a paid service to common things like emergency supply, although it is also marred with a variety of issues in the appropriateness and quality of the referrals. In my personal experience, it has been a tool that is known but not often used.
Is it fit for purpose? Does it solve an issue? What needs to happen to improve it? Should it be scrapped?
