As someone from the UK this is a strange thing to hear about a healthcare institution. In my view the end user is a patient and not a customer.
If a sandwich shop produces bad sandwiches then eventually people stop buying them and shop around. This doesn't work with hospitals. In the worst case, dead people can't shop around.
