- Design
- cluster randomised controlled trial with generalised estimating equations, measured pre-, post- and at three months
- Population
- 77 care communities and 434 staff - 227 from 38 intervention and 207 from 39 control communities
- Primary outcome
- employee satisfaction, person-centred care practices and dementia care confidence
- Effect
- significant improvement in employee satisfaction and in staff perceptions of workplace practices and individualised care; no effect on caregiver-resident relationships or dementia care confidence
Person-centred dementia care in care homes is widely recommended and unevenly delivered, and the usual intervention is training. This cluster randomised trial tested coaching instead: a six-month Care Community Coaching Program aligned to the Alzheimer's Association Dementia Care Practice Recommendations, across 77 care communities - 38 intervention, 39 control - and 434 staff, with outcomes measured before, after and at three months.
The intervention communities improved significantly on employee satisfaction and on staff perceptions of workplace practices and of individualised care and services. They did not improve on staff perceptions of caregiver-resident relationships, or on dementia care confidence.
That split is worth sitting with. The outcomes that moved are organisational - how the workplace runs, how care is scheduled and individualised, how satisfied staff are. The ones that did not are the interpersonal and the skills-based, which are what person-centred dementia care is ultimately about. The authors themselves conclude that skills training needs incorporating into future models, which is a fair reading: coaching appears to change the system around the caregiver without changing what the caregiver can do. No resident outcomes were measured at all, so whether any of this reaches the people living there is untested. Staff turnover in care homes is severe in every country that has looked, so an intervention that improves employee satisfaction is not nothing - but it should be described as what it is.
- Treat coaching as an organisational intervention, and pair it with hands-on skills training if the goal is caregiver-resident interaction
- Measure resident outcomes, not only staff-reported perceptions, when evaluating a care home programme
- Note the null result on dementia care confidence - coaching did not make staff feel more capable
- Consider employee satisfaction a legitimate endpoint in its own right, given turnover rates in this sector
- Remember the outcomes were all staff-reported, including those describing care quality
Why it matters
It distinguishes changing the system around a caregiver from changing what that caregiver does.
Don't overread it
All outcomes were staff-reported perceptions, with no resident-level measures at all.
The statistics, in plain English
Cluster randomisation at the level of the care community is the right design here, because staff within a home influence each other - but it means the effective sample size is closer to 77 than to 434, which limits power. Every outcome is staff-reported, including the ones describing care quality, so the study measures perception rather than practice throughout. The absence of an effect on two of five outcome domains in a trial of this size is suggestive rather than conclusive.
