Abstract
Background: Behavioural and psychological symptoms of dementia (BPSD) are often reported in institutions for the elderly.; Objective: To evaluate the effectiveness of a staff education intervention to manage BPSD in older people with a diagnosis of dementia.; Methods: The trial was conducted in 16 nursing homes; 306 patients with a diagnosis of dementia and presenting BPSD were selected. Nursing homes were randomly allocated to an intervention group or a control group. An 8-week staff education and training programme was conducted in the nursing homes in the intervention group. The main outcome measures were the Cohen-Mansfield Agitation Inventory (CMAI) and an Observation Scale (OS) score. Assessments were done at baseline (W0), at the end of the ‘intervention’ period (W8) and 12 weeks after (W20).; Results: There was a significant decrease in the global CMAI score between baseline and W8 (-7.8; p > 0.01) and between baseline and W20 (-6.5; p > 0.01) in the intervention group but not in the control group. Results of mixed linear models showed that the CMAI global score, the CMAI physically non-aggressive behaviours subscale score and verbally non-aggressive behaviours subscale score significantly decreased in the intervention group (p < 0.001) although there was no significant evolution in the control group. Direct assessment with the OS produced the same pattern of results, with a significant decrease only in the intervention group.; Conclusion: The intervention reduced BPSD in severely demented nursing home residents and this effect was still present 3 months after the end of the programme.; Copyright (c) 2009 John Wiley & Sons, Ltd.
