Patient experience can't be the be-all and end-all of NHS care. After all, doctors have always been easily able to please patients with quackery.
However, medicine has tended to be more doctor-centred than it should be, so an emphasis on patient experience may help to right the balance. An editorial in the BMJ discusses the use of patient experience within pay for performance (P4P) programmes. This sounds as though it has more merit that service-line reporting and management (SLM) promoted by Monitor, although the way SLM has been implemented locally where I live in Norwich has focused on the patient experience (see Monitor example of SLM implementation).
