Data Type Profile: AU Medical Record Number

This identifier profile defines a (MRN) (sometimes referred to as unit record number (URN) or (UR)) in an Australian context. An MRN is an institution’s identifier for a patient’s record at that institution. A patient may have more than one MRN for a single institution due to organisational restructures.

Usage:

• Use this DataType Constraint: AU Base Patient and AU Base Related Person
