After working in the community health setting for a while, the diagnosis of schizophrenia is used in a very liberal way when the patient decides malingering is a solution to their issue with access to resources.
The fact that he was carrying a knife, presented to the appointment, and carried out the murder makes me wonder how much his mental state was impaired vs how much of this is premeditated or ****ty human behavior/antisocial.
Yes, it's easy to get a psychotic diagnosis. Tell the overworked resident, or lazy prison psychiatrist, you hear voices. Something has to be coded, after all. Then you'll get attention from social workers, nurses, and NPs, all of whom are female. It's a nice break from the usual in prison. This is one of the reasons prison guards have a negative view of psychiatry and don't take real psychiatric issues seriously. The guy is a predatory rapist, so likely he knows how to game the system.
It appears the clinic is a "recovery" center. I wouldn't be surprised if it's a CMHC-funded substance unit, given the guy just got released from prison and is likely on Medicaid. I also wouldn't be surprised if no one told the NP about his history. This is a reminder that large organizations do not care about you (or by extension, your safety). The organization exists to rake in hundreds of millions of dollars from third party payors. If employees get hurt or killed, oh well, the organization has workers' comp. You are responsible for your safety.
My patients with Schizophrenia are for the most part very kind people and very vulnerable to exploitation.
The patients that concern me the most re: violence are drug seeking patients angry I won't prescribe their substance of choice and the occasional lifelong criminal that sells drugs and guns.
The majority of patients are benign. But we shouldn't downplay the significant minority of patients with psychotic/manic disorders who get very violent and irrational when off their meds (hello ED psych). The risk is even greater if past violence, substances, personality, not working, Medicaid, outpatient, and under 55.
I'd make a distinction between predatory sex criminals and career criminals who sell drugs/guns (i.e., illegal businessmen). The businessmen are quite rational and predictable in thought and behavior ("Will this crime benefit me monetarily and is it worth the risk? If not, I'll move on").
I feel new evals who are seeking controlleds are generally fine beyond some yelling and foot stomping. The worst are substance seekers inherited from the clinic candyman, as they view you as taking away "my Xanax". It generally helps to have the scheduler warn them in advance controlled substances will likely be tapered off and they should seek another doctor if they wish to maintain them.
