Staff on psychiatric wards at risk for violent abuse

As seen in this news item

In the Italian psychiatric facilities, there are more than 1,000 cases a year of violence against health care workers. And in twenty years 8 of them were killed. The victims are usually doctors and nurses that, in this country, take care of over 3.5 million patients. Very often they are drug addicts who do not have a specific mental disorder, but access these health services because they are the only ones available to the public. This is the complaint of the SIP (Italian Society of Psychiatry), launched for the First National Day of health and safety of the health workers to the care of psychiatric patients, which takes place today in Bari.

Given the admitted inability of Psychiatry to provide any cures, and with this evidence that they cannot rehabilitate people, why would anyone want to join a failed profession?
