NHS Legacy Information Management Maturity Model

This white paper presents the NHS Legacy Information Management Maturity Model (NHS-LIMM), which aims to assist NHS trusts in modernizing their legacy information management systems. The document outlines the increasing pressures on NHS organizations to ensure compliance, interoperability, and readiness for AI-driven healthcare. It details a staged maturity model that guides trusts from fragmented and rigid legacy data practices to intelligent, cloud-native information management. The paper identifies five stages of maturity, ranging from Ad Hoc to Intelligent, each characterized by specific governance, infrastructure, and data utility criteria. Additionally, the white paper provides an implementation roadmap that includes benchmarking current states, digitizing workflows, and adopting AI-driven solutions. Key metrics for success are also outlined, focusing on improvements in data retrieval times, reduction in legacy system maintenance costs, and overall user satisfaction. The conclusion emphasizes the importance of agile, cloud-native solutions in transforming legacy data practices for enhanced care delivery.
