Chronic diseases are now the top cause of death and disability around the world. This creates challenges for global health systems, which are mostly designed for acute care, requiring them to transform to optimise the health of patients living with chronic diseases. The Chronic Care Model provides the best evidence-based framework for optimising diabetes care delivery by modifying essential elements of the healthcare system to support person-centred care. In this article, we review the theoretical basis of person-centred care, with special focus on the Chronic Care Model, and describe the steps involved in performing person-centred care. We also discuss the evidence for the impact of person-centred care on chronic disease outcomes, self-management, as well as individual and healthcare professional (HCP) satisfaction.
