There are a few thousand included on the VRCT. if employers must employ individuals that are regulated by the HPC then I guess they need just enough in each scope of practice to run a service.
I think it's pretty obvious that the VRCT is already influencing the requirements for fully qualified "technicians" already working in healthcare. It's intended to drive standards of training, qualifications and experience, up not down.
VRCT is about laying the groundwork so that individuals who will be eligible to use protected titles working in healthcare, thus be identified as fully qualified, working within the relevant scope of practice, can move over to the HPC register.
It's up to the employer to implement the mandatory aspects of HPC regulation, such as use of protected titles, providing CPD resources, becoming involved in training/education, setting up the career structure within their organisations, etc.
Regulation has benfits as well as drawbacks. Not everybody is going to be eligible. From what I see those that aren't eligible don't seem to be the types that want to progress, want to improve their situation. If they don't want to they don't have to.
The politics of registration, regulation, etc, etc, have been going on for many years. Regulation has been on the way for a very long time. Heads in the sand will not make it go away.
