Background: While Person-centred care is a cornerstone of high-quality healthcare, its application in a high-pressure environment such as the Emergency Department is consistently challenging. Nonetheless, the majority of Person-centred care models are established in Western healthcare systems, raising concerns about their universality. This review addresses this gap by synthesising evidence on how Person-centred care is practised and perceived across varied cultural and systemic contexts, particularly within the Emergency Department environment. Aim To explore current Person-centred care practices in Emergency Departments from the perspectives of patients, nurses, and physicians. Guided by the Picker Institute’s framework, it synthesises the literature to analyse variations in the implementation of Person-centred care across diverse geographical and healthcare contexts. Methods:  This scoping review was conducted in accordance with the Joanna Briggs Institute methodology. Four major databases (MEDLINE, EMBASE, CINAHL, PsycINFO) and grey literature were searched for studies published between 2018 and 2024.  A thematic analysis was performed, guided by the Picker Institute’s dimensions of Person-centred care. Results:  A consistent gap emerged between patient desires for compassionate, inclusive care and the task-focused reality of Emergency Department practice, which is heavily shaped by overcrowding, institutional culture, and burnout. The evidence base is geographically skewed, with most research coming from Western countries whose efficiency-focused systems often conflict with Person-centred care values. Limited evidence from non-Western contexts suggests further cultural restrictions, including hierarchical decision-making and family-centred care dynamics.  This review underscores a significant deficiency of patient-voiced evidence from non-Western healthcare systems. Conclusion: Person-centred care is not a universal approach, but a context-dependent practice that must adapt to diverse cultural and systemic realities. Strengthening Person-centred care in Emergency Departments requires bridging patients’ relational needs with organisational constraints. Moreover, it requires developing culturally relevant strategies to promote effective communication and compassionate care globally.
