Assessing the Effectiveness of an Approach for Vocal Behaviors in Older People Living in Nursing Homes

Between 13 and 60% of older people who live with Alzheimer's disease (ADRD) in long-term care facilities (LTCFs) manifest vocal behaviours (VB) that may seem inappropriate, e.g. moaning, screaming, calling out. These behaviours may indicate ill-being, disturb others, create feelings of powerlessness in family and formal caregivers, and lead to inappropriate medication. Previous efforts to reduce VB have been largely ineffective. A new approach was developed based on finding the underlying reasons for VB through a partnership between family and formal caregivers. The goals are to reduce VB, enhance older people's well-being, and increase family and formal caregivers' empowerment. The approach was tested in a pilot study of 14 triads comprising an older person living with ADRD, a family caregiver and a formal caregiver. The results were promising; overall, it is feasible to implement the approach in LTCF and it has positive effects on older people, family and formal caregivers. Now the investigators propose to assess the clinical and economic impact of the approach in 20 LTCFs with 108 triads like those in the pilot study. The approach will be implemented in 10 randomly selected "experimental" LTCFs; the other 10 (control group) will continue with their usual practices. The investigators will measure VB frequency and the well-being of the older people before, two and four months after starting the implementation. They will also measure the perceived disruptiveness of VB for family and formal caregivers, their ability to work in partnership and their empowerment relative to VB. The investigators will compare data between the control and experimental LTCFs, and calculate cost-effectiveness based on changes in VB frequency. The proposed three-year project aims to improve the well-being of all involved in LTCF by promoting a better understanding of VB and implementing a solution to optimize care. The investigators believe the findings will provide evidence to justify the wider implementation of the approach in LTCF.
