The problem with VRCT and working in the medical engineering field is that it is always looking at things from an NHS only perspective.
What is not taking into account is how many external companies provide the service and maintenance of medical equipment. There is no way the UK are going to be able to insist on a specific degree (or otherwise) course before someone can work on medical equipment.
For me what would be better is to take engineers that have done a general electronics engineering course (ONC, HNC, B-TEC, BSC or whatever) and then insist a short course in undertaken, like the electricians do for the Part P requirement, before you can work un-supervised on medical equipment. This is about the best you could get without the costs being too prohibitive.
The medical companies have a lot of difficulty attracting new staff as it is without putting more barriers in the way!
