Few reports have investigated factors related to the outcomes of day-care attendance. The aim of this retrospective study was to investigate the factors related to the outcomes of patients who attended day-care clinics, with special attention to the differences between hospitalization in the dementia ward and institutionalization.


We analyzed data from 333 patients in consecutive cases who attended day care between 1 April 2000 and 31 March 2010 and then followed them until 31 March 2011. For univariate and multivariate analyses, patients were divided into seven groups characterized by their outcomes: (i) patients who continued day-care attendance (continued); (ii) those hospitalized for physical problems (hospital (physical)); (iii) those hospitalized in the dementia ward (ward (dementia)); (iv) those hospitalized in the psychiatric ward for psychiatric problems (ward (psychiatric)); (v) those institutionalized (institution); (vi) those who stopped day-care attendance by choice (intention); and (vii) those who stopped day-care attendance for other or unknown reasons (others).


Behavioural and psychological symptoms of dementia were the main reasons for hospitalization and institutionalization. Men were easier to hospitalize in the dementia ward. Patients who applied for insurance were more likely to be institutionalized. The differences between patients who were hospitalized (dementia ward) and institutionalized were age and cognitive function.


Patients who were older and had high cognitive function were institutionalized rather than hospitalized in the dementia ward. Patients with severe dementia symptoms were advised to be treated in the dementia ward.
