Despite the prominence of person-centred care (PCC) in nursing, there is no general agreement on the assumptions and the meaning of PCC. We sympathize with the work of others who rethink PCC towards relational, embedded, and temporal selfhood rather than individual personhood. Our perspective addresses criticism of humanist assumptions in PCC using critical posthumanism as a diffraction from dominant values We highlight the problematic realities that might be produced in healthcare, leading to some people being more likely to be disenfranchised from healthcare than others. We point to the colonial, homo- and transphobic, racist, ableist, and ageist consequences of humanist traditions that have influenced the development of PCC. We describe the deep rooted conditions that structurally uphold inequality and undermine nursing practice that PCC reproduces. We advocate for the self-determination of patients and emphasize that we support the fundamental mechanisms of PCC enabling patients' choice; however, without critical introspection, these are limited to a portion of humans. Last, we present limitations of our perspective based on our white*-cisheteropatriarchy** positionality. We point to the fact that any reimagining of models such as PCC should be carefully done by listening, following, and ceding power to people with diversity dimensions*** and the lived experience or expertise that exists from diverse perspectives. We point towards Black, queer feminism, and critical disabilities studies to contextualize our point of critique with humanism and PCC to amplify equity for all people and communities. Theory and philosophy are useful to understand restrictive factors in healthcare delivery and to inform systematic strategies to improve the quality of care so as not to perpetuate the oppression of groups of people with diversity dimensions. *We purposely capitalize Black and use lower case for white to decentre whiteness and as an intentional act of antiracism (see White Homework a podcast series by Tori W. Douglas). *Cisheteropatriarchy describes people with intersecting identities of dominant social groups; cisgender is the gender identity that aligns with the gender you were assigned at birth, hetero means heterosexual, and patriarchy refers to structural systems of power based on maleness where women are often excluded and hold less power. *With diversity dimensions, we refer to subjective lived experience and material realities of people that exist outside the 'dominant minorities' of white-cisheteropatriarchy, meaning groups of people in society who historically and currently hold more power and through this, structurally dominate the norms and possibilities of living for other people.
