MPS Documentation - the Person_ID handbook

Documenting how the Person_ID is generated via the Master Person Service (MPS), to make the current process of linking data in the NHS more transparent and easy to understand.

The Person_ID is a unique patient identifier used by NHS England with the objective of standardising the approach to patient-level data linkage across different data sets. The Data Linkage team has produced a detailed documentation of the data linkage algorithm used to create the Person_ID, namely the Master Person Service (MPS). The figure below is an overview of the process. The full documentation is available in this NHS England site. The MPS handbook particularly focuses on how this algorithm is applied to Hospital Episode Statistics (HES).
