Psychiatric emergency services work can be akin to watching a train wreck without any ability to prevent the wreck from happening. When will the next tragedy involving serious injury or loss of life due to untreated serious mental illness occur? Governments are reactive.
The severe shortage of inpatient psychiatric beds along with overly restrictive inpatient commitment criteria often result in only the sickest of the sick getting admitted to inpatient units. For people with psychosis who lack awareness of being psychotic, brain deterioration often occurs long before sufficient psychiatric treatment is obtained. Early psychosis programs are completely voluntary, thus marginalize those who refuse to engage in treatment because they don't believe that they are ill.
Emergency medical doctors are more likely to discharge to the streets a dangerous patient who is not wanting any treatment, than a dangerous patient who is wanting treatment. They are more likely to move on to inpatient the malingerer who doesn't need treatment, than a psychotic patient who can "pull it together," and cover up symptoms.
