In response to some of the comments; I think it is short sighted and self important to think that GPs are the only healthcare professionals sufficiently trained to be able to see patients attending an urgent clinic. If you leave patients to decide whom they need to see, they will more often than not choose a GP, whether that is appropriate or not. We see this by the numbers of patients that come in with mild cases of tonsillitis, viral infections, D&V etc... This urgent care system removes their choice, deals with their presentation, is supervised by a GP, and is far less burdensome than the traditional duty doctor system. It spreads the clinical decision making to more professionals which reduces the overall load. I can't see how this is a bad thing.
As a trainee, part of what would put me off a specific Practice is a reluctance to accept and embrace change. The GP workload is the biggest it's ever been, why not remove some of the unnecessary/not GP-specific work to other professionals and concentrate more on the multi morbid and chronic conditions.
