Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Aim: To assess the clinical and economic effectiveness of an approach based on the meanings of vocal behaviours (VB) in older people living with Alzheimer's disease or related disorders (ADRD) in long-term care facilities (LTCF) using a pragmatic randomized trial complemented by a qualitative component. Background: Vocal behaviours are common in LTCF; 13 to 60% of residents exhibit them. They may indicate ill-being, are associated with overmedication, are disruptive for others, and induce powerlessness in family and formal caregivers. Studies on interventions to reduce VB have shown limited clinical impacts. In previous projects, the investigators developed and pilot tested a novel approach based on the underlying meanings of VB. The systematic approach comprises family-formal caregivers' partnerships which include regular meetings (at least monthly) to identify the meanings behind VB (e.g. pain, anxiety) and to apply personalized interventions (e.g. gardening, humor). A pilot study conducted in five LTCF demonstrated the feasibility and acceptability of the recruitment and data collection methods, as well as the approach implementation using 14 triads, each made up of an older person with ADRD, a family caregiver and a formal caregiver. The approach decreased the frequency of VB, and increased the well-being of the older people with ADRD. The formal and family caregivers perceived the VB as less disruptive, and felt more empowered relative to them. However, the lack of control group precluded measuring effectiveness versus usual practices and costs. Methods: A pragmatic cluster randomized trial will be conducted to assess the effectiveness of the approach based on the results from the pilot study. A concomitant qualitative component will describe process elements that contribute to the measured effects. The investigators will randomize 20 LTCF to either an experimental (approach) or control group (usual practices), and recruit 6 triads in each LTCF for a total of 108 triads (power of 80%, significance 5%, medium effect size and 40% attrition). They will enroll 10 to 20 triads in the qualitative component. They will collect data, before, two (post-implementation) and four months (follow-up) after starting the implementation of the approach, on VB frequency (primary outcome), medication use, well-being of the older people, perceived disruptiveness of the VB, the partnership-based decision-making and the level of empowerment felt by family and formal caregivers. Additionally, they will collect data on the setting (e.g. number of beds, turnover rate), and cost (e.g. trainer, medication). Qualitative data will also be collected with individual semi-structured interviews. The investigators will analyze the effects of the approach using a mixed-model of covariance with baseline measures, and characteristics of participants and settings as covariates. They will also calculate a cost-effectiveness ratio, and do a content analysis of qualitative data. Expected outcomes: This project will provide evidence on the effectiveness of a novel and generalizable approach to increase the well-being of vulnerable older people, as well as family and formal caregivers. If effective, it may be implemented on a larger scale and adapted to other behaviours (e.g. aggressive behaviours), all of which is aligned with recommendations for research in dementia care.
