We have been discussing that new Nurse call/help line in our classes at uni.
A few people have tried it, and no one is very happy with it, as if there is even the slightest chance that anything is wrong they advise you to go to the Emergency room anyway (yet arent they meant to be reducing the amount of ppl in the emergency rooms?). I can understand why they do that though, because of the fear of litigation. Its also not very effective because its relying on people to tell them what is wrong, and people often omit important details that they think aren't necessary... thus the nurse really needs to see the patient to be able to diagnose properly.
I once called the RCH to speak to a nurse about Aidyns allergy, and the nurses said they werent allowed to give me any info/advice over the phone due to legal reasons... so I wonder how that nurse call line could be any different?
