Personalised care is widely recognised as a mechanism to support individuals with long-term conditions and to transform health-service delivery, yet systematically evaluating how personalised care is implemented remains poorly developed. This review aimed to map and describe the range of instruments, tools or methods designed to assess, evaluate or measure personalised care delivery from the perspectives of healthcare practitioners and/or service users. A scoping review of literature published from 1990 until December 2024 was conducted, following established methodology for identification, screening, charting and synthesis of evidence. From 3,851 initial records, 172 papers were included—103 reporting the development of a new instrument and 69 describing the adaptation of an existing tool. In total, 101 unique personalised-care instruments were identified. The vast majority (94%) of instruments targeted service-users (patients); with eight focussing on healthcare professionals and one on caregivers. Content analysis of instrument items generated six overarching domains: Understanding the Person; Understanding Capability; Understanding Behaviour; Personalised Care Interventions; Experience of Care; and Wider Determinants. Notably, 81% of instruments were designed for use in a specific clinical population (most commonly diabetes), and 80% focused on supported self-management, with fewer aiming at shared decision-making or broader personalised-care processes. No instrument was found to cover all six domains comprehensively, nor to span multiple stakeholder perspectives or multiple long-term conditions. The review highlights a vast number of condition-specific tools but an absence of broadly applicable, system-level instruments for personalised‐care delivery evaluation. Future work should prioritise both instrument development and application; incorporating healthcare professional and system views, and support monitoring of personalised care delivery across whole systems. These findings provide a framework (PCED-6) to guide selection and development of personalised-care evaluation instruments and identify important gaps for further research and practice implementation.
