@entity1 @entity161 @entity734 @entity146
In July 2001, @entity146 ( @entity146 ) were investigated in Japan using a questionnaire to clarify current and recent problems in 79 @entity146 . The questionnaires were sent to wards, @entity1 and psychiatrists and were returned by 72.2% overall. The number of admissions per ward was calculated as 21 @entity1 per one month, and comprised half of all admissions to the hospital. 50% were @entity161 , 17% were affective disordes and 16% involved @entity734 . Seventeen @entity1 were discharged from @entity146 per one month, and comprised 43% of all @entity1 discharged from the hospital. These results indicate that both 21 @entity1 admitted and 17 @entity1 discharged per month and needs to maintain the essential standard for @entity146 and the standard should be come more flexible as admission from the other unit of ward than @entity146 . As rate of re-admission within 3 months after discharge was around 10% of the total number of @entity1 in the ward, 3 months was considered suitable length of acute treatment in the field of psychiatry in Japan. There was one psychiatrist working in @entity146 , and specialized psychiatrists had 17.4 @entity1 , the most number of @entity1 among types of psychiatrist. Simulations of one psychiatrist to 16 and to 32 @entity1 in @entity146 were performed to determine how many psychiatrists were needed for a ward. When the ratio was 32 @entity1 to 1 psychiatrist, it was necessary to increase the number of psychiatrists to a ward by 1, and in the case of 16 @entity1 , 1-3 psychiatrists were needed. These indicate the standard number of psychiatrists for @entity146 should be at most one psychiatrist for the ward or all of the psychiatrists working in @entity146 should be allowed to work simultaneously in other wards. Preparing wards to treat acute phase @entity146 @entity1 is a very important role of each @entity146 hospital, the standard for @entity146 should include not only a high level of medical staff, but also preparing easy criteria for each hospital.
