Similar but different entity cluster

Identifying and definitional attributes

Metadata item type:Data Set Specification
METeOR identifier:554856
Registration status:Health, Standard 05/10/2016
DSS type:Data Element Cluster
Scope:

The Similar but different entity cluster includes data elements that define identifiers that have similar identifying information but belong to different entities. This cluster also describes information about the organisation or individual provider which confirms that similar records are not duplicates and the date this confirmation occurs.

Collection and usage attributes

Comments:

Provision should be made in systems for regular monitoring of new and changed entries which are similar enough to possibly be the same entity, for example identical twins or an identically named parent and child. It is necessary to be able to indicate clearly that two entries are not actually duplicates and ensure they do not appear on lists of potential duplicates for follow-up.
