Understanding the Dementia Care Triad: Findings From a Longitudinal Qualitative Study With People Living With Dementia, Their Carers, and Their Healthcare Professionals

<b>Background:</b> Best healthcare practice for people with dementia encourages the inclusion of family members or carers, alongside enabling people with dementia to make their own decisions. Dementia care thus often includes the person with dementia, their carer, and their healthcare professional (HCP): a dementia care triad. Understanding how this triad is developed and navigated may improve future dementia care services. <b>Methods:</b> A longitudinal qualitative approach was used to interview 30 people with dementia, 31 family carers, and 7 healthcare professionals in England between May 2020 and March 2021. Data from three interview time points were transcribed and analysed using reflexive thematic analysis. <b>Findings:</b> The relationships within a dementia care triad were initially built on the dyadic relationship between the person with dementia and their family carer and any pre-existing relationships with their HCP. The nature and proximity of the carer to the person with dementia influenced how triadic relationships in dementia care formed and functioned, with spousal and co-resident carers more actively involved in healthcare interactions. Further positive development of a triad required confidence in the HCP, and shared perspectives on balancing the involvement of the carer and the independence of the person with dementia, with considerations of autonomy and risk, and which did not always follow a linear transition. While increased carer involvement often supported the person with dementia, it sometimes led to their exclusion. Engagement by healthcare professionals varied, reflecting inconsistencies in applying person-centred care. <b>Conclusions:</b> The findings of this study suggest a need for clearer, more consistent approaches that support dynamic carer roles while preserving the autonomy of the person with dementia. This study provides additional considerations in relationship dynamics that inform our understanding of the dementia care triad.
