The NHS Single Patient Record is a national programme introduced through the NHS Modernisation Bill in May 2026. It places a legal duty on all NHS providers to share patient data so that every authorised clinician has access to a complete, consistent view of a patient’s medical history, regardless of where care is delivered. From 2028, patients will be able to access their own SPR through the NHS App. The programme begins with maternity and frailty care, with wider rollout across England to follow in phases.

An Electronic Patient Record (EPR) is a digital record held by a specific organisation such as a trust, a GP practice, or a community provider, capturing the interactions that organisation has with a patient. The Single Patient Record is a national initiative that connects those separate EPRs, giving clinicians across different care settings access to a joined-up view of the full patient history. The EPR is where care is recorded; the SPR is how those records are made accessible across the system.

When the same patient exists under multiple records — in one system or across several — clinicians cannot build a complete picture of their care history. Duplicate records mean fragmented medication histories, missing diagnostic results, gaps in treatment records and significant administrative burden for staff manually reconciling conflicting information. Connecting systems through the SPR does not resolve duplicate records. It makes them more visible and their consequences more serious.

Patient identity resolution is the process of determining, with confidence, that records from different sources represent the same individual. It applies matching logic across demographic fields such as name, date of birth, address, NHS number; and produces a scored decision about whether two records belong to the same person. Where records agree on all fields, a deterministic match is made. Where fields differ, probabilistic matching assesses the overall likelihood and assigns a confidence score which data governance teams can review, approve or override.

A golden record is the single, authoritative version of a patient’s identity, built from the best available information across all contributing data sources, with conflicting field values resolved according to survivorship rules. It does not replace any source system record; it provides a trusted reference point for downstream systems, analytics tools and integration platforms. Golden records are maintained and updated as new information arrives and form the foundation of any effective Master Patient Index.

The SPR depends entirely on accurate patient identity. If the same patient exists under different names, dates of birth or identifiers across contributing systems, the SPR cannot link those records correctly. The result is either a fragmented view, where the clinician sees only part of the patient’s history, or an over-merged view,  where records from different patients are incorrectly combined. Both outcomes carry clinical risk. Data quality must be addressed at the source, before records are connected through the SPR infrastructure.

WinPure operates as a desktop-first, local processing platform. It accepts data from any source system that can export to standard file formats, processes it entirely within your own infrastructure and outputs clean, matched and deduplicated records that feed back into your target systems. No cloud connection is required. No data leaves your environment. An API is also available for teams who want to embed the matching capability into custom applications or automated pipelines.
