2. NHS Begins AI Copilot Rollout to 505,000 Clinicians Across England

Windows News / NHS England · Healthcare & Pharmaceutical

NHS England has begun rolling out Microsoft 365 Copilot to 505,000 clinicians and support staff across England, following a successful pilot with 30,000 workers across 90 organisations that saved an average of 43 minutes of admin time per person per day. The AI assistant helps staff draft clinical letters, manage discharge processes, analyse data, and handle meeting administration — freeing up more time for direct patient care. The full deployment is expected to be completed by October 2026, with data locked to UK Azure regions and contractual protections preventing NHS patient data from being used to train AI models.
