Put simply, money overcomplicates any relationship. Whether that be between partners or doctor and patient. The ethos behind the NHS is a free and impartial healthcare system that acts with the greatest interest of the patient. In my opinion, by adding monitary value to the relationship between doctor and paptient, both the impartiality and ethos of the system is lost. There is the real danger that doctors would feel obliged to rush appointments to cut costs, while patients may not be getting the full attention that they need to treat often complex and deep rooted problems. 

It is unfortunate that the management culture of the NHS and primary care since the late 90s has been focused on meeting copious amounts of targets, as opposed to letting the NHS do its job of treating its patients. I agree that there needs to be some form of accountability for all trusts, but this hypothetical scenario makes an extremely important point. That is, the more we try to value (monitarily) the relationship between doctor and patient, the more we will ultimately devalue it. I don't pretend to be a self confessed expert on the NHS, I am simply an undergraduate student stating things as I see them. Certainly, there are no easy fixes to the NHS, but in giving doctors less time to treat we are actually failing our patients.
