Abstract
BACKGROUND: In Japan, the number of beds and average length of stay in a psychiatric ward are greater than in other developed countries. OBJECTIVE: The present study aimed to investigate the association between family variables and the length of stay of patients with mental and behavioural disorders in a private psychiatric hospital in Japan. METHODS: The medical records of patients discharged during a one-year period (n=56: men 50.0% excepting 27 patients discharged due to death were re-examined regarding age, laundry type (self-washing of clothes, family washing or supplier washing), number of family visits per one month while hospitalised, and family structure prior to hospitalisation. A length of stay greater than six months was considered the cut-off point for a long hospital stay. Bivariate logistic regression analyses were conducted to identify factors independently associated with the length of stay, adjusted for sex, age, and mental and/or behavioural disorders according to the criteria of the International Statistical Classification of Diseases and Related Health Problems. RESULTS: The bivariate-adjusted odds ratio (95% confidence intervals) for in-patients hospitalised for more than six months was 0.08 (0.01, 0.48) for those who used family washing (p = 0.006) compared with those who used supplier washing. The number of visits per month and family structures before hospitalisation were not significantly associated. CONCLUSION: These results suggest that within a private psychiatric hospital in Japan, family washing is associated with shortened stays and frequency of family visits, while family structure is not associated with these factors.
