Research background

In Japan, patients with mental disorder having a risk for harming self or others are hospitalized by the prefectural governor’s order.

Research motivation

We have to know the outcome of patients who were hospitalized involuntarily.

Research objective

To clarify the performance and outcome of the scheme of involuntary hospitalization by the prefectural governor’s order.

Research methods

Retrospective cohort by examining medical record of hospitals accepting involuntary hospitalization.

Research results

A total of 394 subjects were examined. Approximately a fourth at 1 year, and a third at 2 years after the census had unknown prognosis. Approximately a third was identified as good prognosis. Discussion with external specialists before discharge were associated with good prognosis.

Research conclusions

Psychiatric hospitals in Japan have limited ability to track the prognoses of patients who were hospitalized involuntarily by the prefectural governor’s order.

Research perspectives

Constructive discussion with external specialists before discharge is possible to improve the outcome of the patients with mental disorder. To confirm this hypothesis, a prospective cohort study is necessary.
