He WAS seeing a doctor, his family confirmed it. The doctor thought he was doing better, so decided to start to wean him off the meds he was on (that were working but the doctor thought he might not need them any longer). He then stopped going to the doctor and his family said his behaviour changed and he moved away. The rest is history.
My concern with this, is whats the escalation process if this action happens to another patient, and they then stop going to the doctor. Who does welfare checks? Anyone? I'd hazard a guess not, but this highlights how inaction can increase risks to the public. Had welfare checks been done, even his dad said he moved back in with them and they found a whole bunch of knives which is dad confiscated them from him and he got angry and ultimately moved out again. From what the family said, they did everything they could to help him, but the system seems to have failed him.
Its all well and good changing treatment methods, but then what happens if they stop taking them. What escalation steps exist for the doctor. It can't just be that they are forgotten about, there has to be a process that protects the individual as well as the community around them.
