[Necessity of psychiatrist's support for critical care medicine].

The department of critical care medicine of Sapporo City General Hospital has been accepted 9,476 patients for past 10 years since opening. About 20% of all the patients who were hospitalized were due to accidents by backgrounds of psychiatric disorders. Main disorders are schizophrenia, manic-depressive psychosis, neurosis, alcoholism and so on. Suicides and to harm other persons are occurred unexpectedly and sometimes make the institute face to serious social problems against human rights. For protecting these tragedies, supports by psychiatrists are necessary. Our department has been connected very closely with our psychiatric department since starting. They suggest us to make correct diagnosis and treatment, ways to contact with such patients and their family properly. It's still very hard subject to know the possibility of these accidents in advance, but we strongly hope to promote these psychiatric sciences for protecting tragedies.
