Background and aim: Despite person-centred care (PCC) being a cornerstone of high-quality care, older persons in Swedish residential care facilities (RCFs) report declining satisfaction with their influence and involvement in care decisions. This poses risks to their health and well-being. Staff also highlight unmet psychosocial needs among residents, as routines prioritise medical tasks. When staff are unable to deliver person-centred care, it may lead to job strain and reduced well-being. Currently, there is a lack of validated and sustainable models for implementing PCC in RCFs. This study is part of ProFoUND PCC - a Program For User-based Nursing Development in Person-Centred Care, which aims to co-create such a model together with staff and other stakeholders. The present study explores staff experiences of delivering and enacting PCC in everyday practice, providing baseline insights that will inform the subsequent co-creation of a contextually grounded PCC model. Methods: Semi-structured individual interviews were conducted with social and healthcare staff (n=30) from two residential care facilities. Interviews were conducted in person or digitally, transcribed verbatim and analysed using qualitative content analysis.   Results: Preliminary findings indicate that PCC is primarily enacted through everyday routines and interactions rather than through formal plans or documentation. Staff emphasised respect for residents’ individuality and autonomy but described challenges such as time pressure, varying competence levels and inconsistent organisational routines. Leadership and workplace culture emerged as important influences for translating person-centred values into daily practice. Conclusions: Preliminary interpretations suggest that achieving sustainable PCC may rely less on individual motivation and more on organisational conditions that enable it. Supportive leadership, opportunities for competence development and a collaborative culture appear essential for fostering person-centred care within RCFs.
