NHS England Digital
NHS England Digital (formerly NHS Digital) is the official statistics and data body for health and social care in England. Its catalogue covers general practices, hospital-level mortality (such as the Summary Hospital-level Mortality Indicator), mental health services, population and public health, NHS outcomes frameworks, prescribing, and workforce, alongside structural reference data about NHS organisations through the Organisation Data Service.
Most data is reached through the data pages on digital.nhs.uk, where statistical publications are released on regular schedules with downloadable CSV and Excel files plus supporting methodology notes. The Organisation Data Service data (codes and details for every NHS organisation, GP practice, and care provider) is a particularly clean, list-shaped resource that maps neatly onto records you can embed. For a RAG system, the accompanying methodology and definitions documents are as valuable as the tables themselves: they let an assistant explain what a figure means, not just quote it.
This source is best for a UK-focused health assistant: answering questions about NHS structure and organisations, summarising population health indicators, or grounding responses in official mortality and mental-health statistics. It pairs well with the narrative and definitional context those publications provide.
Two things to watch. First, everything published here is aggregated or anonymised in line with national standards, and small counts are suppressed to protect privacy, so you will not find patient-level records; access to identifiable data needs a separate, governed application and is out of scope for an open RAG build. Second, the data is released under the Open Government Licence v3.0, which is generous (commercial and personal reuse are both fine) but requires attribution, so credit NHS England as the source in anything you publish. Alongside it, OHID's Fingertips profiles and the Office for National Statistics cover overlapping population-health and demographic ground, and are worth combining when you need a fuller picture of health in England.
