| Anonymous information |
Information that is not personal data because no person is identifiable by reasonably likely means. Context and recipient capability matter. |
| Confidential patient information (CPI) |
Patient information subject to the common-law duty of confidentiality; the statutory definition for section 251/COPI and opt-out purposes must be checked for the flow. |
| Controller |
The person or organisation determining purposes and means of processing. Joint controllers decide these together; a processor acts on documented instructions. |
| Direct / individual care |
Care, diagnosis, treatment or support of a particular person. The precise operational-policy definition must be checked where an exemption depends on it. |
| DCB / DAPB standard |
An NHS information standard or collection bearing an identifier. Its notice, scope, status and dates determine applicability. |
| DPIA |
Data protection impact assessment. Required before likely high-risk processing and useful as a structured design record for significant sharing. |
| ISN |
Information Standards Notice: the authoritative notice that states scope, status, implementation and conformance details for an NHS information standard. |
| PHC |
Primary health care; this wiki focuses principally on general practice but includes connected primary-care services. |
| Pseudonymised data |
Personal data processed so it cannot be attributed without additional information kept separately. It is normally still personal data for a party able to re-identify. |
| Section 251 |
The NHS Act 2006 route implemented through COPI regulations for certain processing of confidential patient information without consent, subject to approval and conditions. |
| Section 251B |
A qualified duty on relevant health and adult-social-care bodies to share information likely to facilitate an individual’s care when in their best interests, subject to statutory limits. |
| Standards Directory |
NHS England’s discovery service for published and future standards. It signposts authoritative notices/specifications; the listing alone is not proof of universal mandate. |
| Type 1 opt-out |
A GP-system-level choice preventing identifiable GP record data leaving the practice/system for purposes beyond direct care. It is distinct from the national data opt-out. |
