I briefly worked at a hospital and I agree, many doctors and nurses treated patients differently because of their psychiatric history. I'll admit, I did too for certain conditions, particularly because it was the long-term care section of the hospital and some of the newly admitted patients had a history of suicidal attempts, so the nurses were telling each other and myself to be especially vigilant and not "set him/her off", as though if we made the person uptight they'd instantly try to kill themselves. It was as though they were intentionally walking on eggshells. For non-suicidal patients with a psychiatric history, nurses were either reluctant to tend to the patient or were less sympathetic with poor bedside manners. Several of the patients were diagnosed with depression and some of the nurses told me the patient just whines and to ignore it. When they complained of the hospital food (because it isn't that tasty), some nurses came down hard on the patients by saying other patients eat the food and it's just the depression talking.

However, despite this, there were some nurses that were very sympathetic. One in particular was sympathetic to all patients no matter what they had or how they acted but if another nurse or even a doctor didn't treat a patient, collegue or visitor with enough respect, she'd practically bite their head off. She would always say that nurses and doctors are well-educated individuals, so they should show their maturity.
