Person-centred care is a term that has been used frequently in literature since the mid-1990s. This type of care requires health care staff to use person-centredness as a focus for developing relationships and plans of care. In an attempt to define person-centredness, a literature review was undertaken as a means of developing a concept analysis. This led to profiling attributes of person-centredness developed from the work of early theorists and authors as they began to recognise the importance of the ethical and legal rights of people and the importance of holistic care in maintaining wellbeing. However, in the literature, the term person-centred was often interchanged with terms such as patient or client-centred which may lead to confusion. This concept analysis shows that many of the attributes of person-centredness are indeed relevant to patient and client centred care. However, the connotations behind client and patient may appear to shift the balance of power to the health carer by concentrating on the illness rather than the person. Therefore, clarification of the term person-centredness may assist future researchers, practitioners and authors to apply one term only until evolution leads to further definition or change.
