Katherine Murphy, chief executive of the Patients Association, said:
"It is so complicated and confusing to navigate from a patients point of view. I'm not sure how it's going to help."No one wants to be ill - or indeed in hospital - so asking people to recommend a hospital is not like asking someone to recommend a hotel.
"Asking that question is not going to address some of the failures that there are in the NHS. This could really be seen as a smoke screen to cover some of the more fundamental issues that need to be addressed - like the issue around poor care that so many elderly people experience on a daily basis."I think that it could be quite misleading from a patient's point of view."
She also said that patients might not give honest answers for fear of "retribution":
"If you had a nurse looking after you for a week and you were likely to need the services of the hospital again in the future you're not going to put down anything but a favourable response and that's why it is misleading."
NHS England has published the results of a nationwide survey of patients, which is being described as "Tripadvisor for the NHS".
With a fanfare and a tweet from Number 10, the curtain rises on the NHS Friends and Family rating system but what do the results mean?
