Predicting falls from behavioral and psychological symptoms of dementia in older people residing in facilities.

AIM: The aim of the present study was to examine whether behavioral and psychological symptoms of dementia at the time of admission could be a predictor of falls in older people with dementia residing in geriatric health service facilities.

METHODS: Three geriatric health services facilities located in Fukushima Prefecture, Japan, were the targeted facilities. Of the 305 people admitted between May 2013 and November 2014, 242 (74 men, 168 women) who scored ≤20 points on the Hasegawa Dementia Scale-Revised were targeted for analysis. A total of 15 items from the Long-term Care Certification Questionnaire Group 4 were used to assess behavioral and psychological symptoms of dementia, and were compared by the presence or absence of falls.

RESULTS: Of the 242 participants, 153 were non-fallers and 89 were fallers. After adjusting for sex, age, Revised Hasegawa Dementia Scale-Revised, degree of care (which showed a significant relationship with falls in univariate analysis), activities of daily living and history of falls, the influence of behavioral and psychological symptoms of dementia on falls was examined, and showed a significant association with falls and a significant increase of hazard ratio for the behavioral symptoms "wandering" 2.23 (95% confidence interval 1.35-3.68) and "agitation" 1.94 (95% confidence interval 1.24-3.04).

CONCLUSIONS: Because the risk of falling is high for residents who at the time of admission have the behavioral and psychological symptoms of dementia of "wandering" and "agitation," it is necessary to predict the possibility of falling at an early stage, monitor the residents and adjust the environment.
