To organise more fully-staffed shifts you would need a lot more staff = more costs. The spin factor of Hunt's 'seven day week' health service is so obvious as well as the fact that he has never actually explained what he thinks it means. Hospitals do offer a 24/7 service but at some times (2 am or Sunday afternoon, for example) it's largely an emergency service. If you need to see a doctor at 2 am it should be because it's urgent. If it isn't urgent, surely you can wait till 8 am? And as Carolynswalsh says, to offer a full service all round the clock would need all the hospital staff, not just doctors. There must be some points in the 24 hours and the 7 days when even Hunt thinks hospitals do not need to offer a full service with a full complement of doctors, nurses, cleaners, labs, pharmacy, X-ray, scans, receptionists, secretaries, admin, physio, social workers, transport, porters, coffee shop.....
