The concept is that anyone who’s had some experience in the NHS can comment on what happened and their experiences are shared with other potential patients and the NHS. Or as they put it:
As well as allowing everyone to see what patients are saying about their services, it also offers a way to feed the experience of patients back to the NHS so that their insights and ideas can be put to good use.
Now if that doesn’t have the potential to be disruptive technology I don’t know what does.
