It's not "shouting down". It's trying to get heard. Do you think the patient questionnaires and annoying patient satisfaction texts the NHS keep sending, are going to achieve anything positive for patients? I don't, because the resources are not there/mismanaged.
My current experience is that some hospital departments are very well-run and provide a good, if very bare-bones service. They are all chronically understaffed and overwhelmed. Some staff are under-trained and can't communicate in a way that is safe for the patient.
1 of the nurses on my recent hospital stay spent an hour of the night shift bitching about patients and complaining in earshot of patients about the job, the workload (half-empty ward with only 3-4 patients and at least 3 members of night staff) and also tried to guilt-trip me for staying in overnight for an op that is only a day case because the NHS is broken.
Things like that just raise anxiety and make your recovery needlessly hard.
And the GP system is mostly useless and sometimes dangerous and life-endangering, unless you already know more or less what treatment you need and are prepared to argue and fight for it.
Co-pay system urgently needed.
