I personally know of cases where meds were increased when they were not working and they just cused more problems and were not stopped.
Further I know of places where the “professionsals” had to be onboard with the unofficial policies of keeping people doped up no matter how bad it was for them of they would be fired in such a way that they had extremly little chances of getting those in charge of these places in any kind of legal trouble.
Besides that, it is well known, that most infections people get happen inside the hospitals, these days and there are an overwhelming number of cases where limbs were wrongly amputated
when the patient simply came in for a biopsy, or something like that.
