Implementing person-centred care is often considered difficult in congested emergency rooms. The purpose of this study was to understand person-centred care experienced by emergency room nurses in depth and examine the essence of emergency room nurses’ lived experience of the person- centred care. Eight nurses working in the emergency room of a large hospital in South Korea and who had over six months of experience were surveyed via semi-structured interviews in February 2019. The data were transcribed and analysed using Colaizzi’s framework. The major findings related to person-centred care experiences among emergency room nurses were: (1) feeling distanced from patients; (2) guilt and frustration; (3) accepting patients’ symptoms and emotions as they are; (4) person-centred care as a domain of nursing that cannot be replaced by machines; and (5) nursing as an art wherein the minutest details make a difference. Providing person-centred practice in the emergency room is difficult, but it will not only improve the quality of patient care but also increase the job satisfaction of nurses. Based on an in-depth understanding of person-centred care experienced by emergency nurses, it will contribute to enhancing the quality of nursing care in the emergency room.
