Individual Health Identifier (IHI) Data Dictionary

Definition

An Individual Health Identifier is a number that identifies each person who has used, or may use a health or social care service in Ireland.  Each individual will be assigned their own personal number which is unique to them.  The main benefit of having an Individual Health Identifier is to uniquely identify each service user and therefore, improve patient safety by reducing errors that might happen, such as ensuring patients receive the correct medication, vaccinations, and treatment.

 

The IHI is established first and foremost as a patient safety mechanism.  It also allows for a new level of auditability and traceability for healthcare information by providing a record of who accessed information and when.  No medical information is contained within the IHI register.
