Predictors of institutionalization in users of day care facilities with mild cognitive impairment to moderate dementia.

Background: Most people with dementia wish to remain at home for as long as possible. Therefore, it is important to know the predictors of institutionalization, especially those that can be influenced. The aim of the present study is to identify predictors of the institutionalization of people with mild cognitive impairment (MCI) to moderate dementia who attend day care facilities (DCFs) throughout Germany.

Methods: This study is a secondary analysis of longitudinal data from 371 dyads comprising a cognitively impaired care receiver (CR) and a caregiver (CG). The data were collected in DCFs and via telephone interviews at three measurement points. To investigate the extent to which 16 variables could predict the institutionalization of the CRs between the 6- and 12-month follow-up, in the first step bivariate Cox regressions were calculated. In the second step, significant predictors were included in a model using multivariate Cox regression.

Results: Between the 6- and 12-month evaluations, 39 CRs moved into an institution. The risk of institutionalization of people with MCI to moderate dementia attending a DCF increased significantly (p < .05) when the CRs showed more neuropsychiatric symptoms (Hazard ratio (HR) = 1.237), when the CRs and their CGs did not live together in the same house (HR = 2.560), or when the care level of the CRs is low (HR = 2.241).

Conclusions: Neuropsychiatric symptoms could be a possible starting point for therapeutic interventions that are designed to delay or prevent institutionalization. CG who do not live with their CR in the same house and CG who care for a CR with impairment in performing daily routine tasks care are particularly likely to make the decision to institutionalize the CR. For this group, advice and support are particularly important.
