In current psychiatric practice, there are patients who are obliged to stay in hospital despite there being no medical therapeutic need ("social hospitalization"), causing problems such as affecting healthcare expenditure and threatening patients dignity. The Ministry of Health, Labor and Welfare announced that social hospitalization of 172,000 cases should be resolved in the following decade; and the healthcare is being transformed from hospital-based to community-based. However, many patients have difficulty with discharge because of various reasons, resulting in prolonged hospital stays. Some patients have prominent hospitalism and negative symptoms in addition to an unstable clinical condition, and have defects in thinking independently. Negative attitudes to discharge as well as social skill defects including personal relationships and monetary management despite discharge-intention hamper discharge. Some patients who have difficulty with discharge are overaccustomed to the hospital environment, and lose sight of the goals, which lead to reduced motivation; protracted monotonous lifestyle; and reduced social relationships, resulting in impaired quality of life. In this study, we investigated what sort of defects in social skills and associated anxiety hamper the discharge, and performed the social skills training (SST) in eight patients to promote discharge. Ikebuchi describes that "the intervention of SST is performed as a result of a lack of assurance of social life skills (referred to as social skills, interpersonal skills, societal skills, etc.) towards others who have some broad social life difficulties; thus, the goal is their acquisition (or reacquisition) based on learning theory. The targets, therefore, are schizophrenia, and a host of other mental, developmental and intellectual disabilities, and this is spreading widely to adaptive support for children at school and corrective education for those who run afoul of the law." In a prior trial, Yamaguchi addressed the effect of team-based intervention through SST in the group-based discharge support for long-term inpatients. However, no previous studies incorporated living conditions in a geographic region where SST is performed for the assessment of effectiveness. Hospital X is located in a mountainous area with a paucity of public transport system, where the management of patient-owned money is supervised by hospital staff. This study is aimed to determine the effect of SST in those hospital conditions on patients who had difficulty with discharge, and suggest a STT program adapted to hospital conditions. The program taking the hospital characteristics into account was effective and therefore could be recommended for other hospitals with similar conditions to Hospital X. The skill-acquisition can reduce stresses associated with personal relationships in social life, although that effect does not directly lead to hospital discharge. In addition the improvement in social skills seemed to be discharge-promoting.
