Abstract Background Person‐centered care provisioning (PCC) is seen as the golden standard for dementia care. Positive evidence has been found for PCC, the level of person‐centeredness of care is positively associated with residents’ quality of life, quality of care an wellbeing. When providing PCC, care and support are provided in line with the needs, preferences and capacities of people with dementia. In long‐term care facilities, needs and preferences of people with dementia are not always obvious, due to the relatively high levels of cognitive impairment. This, and amongst others time constraints might hinder high PCC by care professionals. However, there is some evidence that certain organizational and environmental conditions, such as satisfactory leadership, interdisciplinary collaboration, and continuing education, lead to higher PCC. In order to facilitate care professionals as much as possible in providing PCC, more insight is desirable. This study aims to provide more insight into the modifiable factors that contribute to person‐centered care for people with dementia in Dutch long‐term care facilities. Method A cross‐sectional design was applied. Data were collected during the fifth assessment of the Living Arrangements for people with Dementia (LAD)‐study from April 2019 until February 2020. Care professionals working in psychogeriatric units in long‐term care facilities filled in an online survey. Organizational characteristics of participating long‐term care facilities were inventoried. The Dutch version of the ‘Person‐centred care questionnaire’ (PCCq) was used to assess the degree of person‐centred care provided in a long term care unit/location. Modifiable factors potentially impacting the level of provided person‐centred care with regard to staff characteristics (e.g. autonomy, education), organizational features (size, involvement of family in care), and culture (e.g. learning climate) were included in multiple regression analyses. Result In total 58 long‐term facilities were included in the ...
