Background: It is twenty years since the US Institute of Medicine (IOM) defined quality in healthcare, as comprising six domains: person-centredness, timeliness, efficiency, effectiveness, safety and equity. Since then, a new quality movement has emerged, with the development of numerous interventions aimed at improving quality, with a focus on accessibility, safety and effectiveness of care. Further gains in equity and timeliness have proven even more challenging.

The challenge: With the emergence of "service-oriented" systems, complexity science, the challenges of climate change, the growth of social media and the internet and the new reality of COVID-19, the original domains proposed by the IOM invite reflection on their relevance and possibility for improvement.

The possible solution: In this paper, we propose a revised model of quality that is built on never-ending learning and includes new domains, such as Ecology and Transparency, which reflect the changing worldview of healthcare. We also introduce the concept of person- or "kin-centred care" to emphasise the shared humanity of people involved in the interdependent work. The change of Person Centred Care to Kin Centred Care introduces a broader concept of the person and ensures that Person Centred Care is included in every domain of quality rather than as a separate domain. The concentration on the technological aspects of quality is an example of the problem in the past. This is a more expansive view of what "person-centredness" began. The delivery of health and healthcare requires people working in differing roles, with explicit attention to the lived realities of the people in the roles of professional and patient. The new model will provide a construct that may make the attainment of equity in healthcare more possible with a focus on kindness for all.
