“…Several studies have explored interprofessional collaboration between informal caregivers of persons with dementia and healthcare professionals in home care (HC), in nursing homes and during nursing home transitions. These studies mainly showed that informal caregivers act as caregivers ( White et al, 2018 ); provide person-centred information to stimulate tailored dementia care ( Häikiö, Sagbakken, & Rugkåsa, 2020 ); make decisions regarding assessments and care plans ( Dalgarno et al, 2021 ; Hughes, Woods, Algar-Skaife, Jelley, & Jones, 2019 ); facilitate continuity and management of care ( Bunn et al, 2017 ); and contribute to the overall quality of life ( Hughes et al, 2019 ) of persons with dementia in HC. Furthermore, in nursing homes, interprofessional collaboration between informal caregivers and nursing home staff is important as well due to their continued involvement in ( Backhaus et al, 2020 ), for example, providing personal care ( Häikiö et al, 2020 ; Roberts & Ishler, 2017 ); watching over the care process ( Hoek et al, 2020 ); providing psychosocial support ( Gaugler, 2005 ); and providing support in solving problems ( Jang, 2020 ).…”
