ISD Data Dictionary - Introduction
This publication comprises definitions and codes for data collection within the NHSScotland.
Standard definitions and codes are of fundamental importance to data quality and integrity and should be used by NHSScotland staff of all disciplines, particularly those involved in the collection, processing and analysis of information.
Many information systems need to interchange data with other systems. To achieve this, systems must send and receive data conforming to standard definitions, standard codes and standard field lengths.
Liaison is taking place on a regular basis with the NHS in England, Wales and Northern Ireland with the objective of achieving UK standards where possible.
The Definitions Team at ISD is responsible for the content of this publication. We continue to welcome comments on this and other relevant publications. All queries and comments should be directed in the first instance to:
