Enter the patient name as in EPR.

Data Processing at main office

Name changes over time

If an inconsistency is found between old and current records,

  • edit only if there is something incorrect, e.g. a typo
  • use the value in the EPR for the correction
  • we change the old entries to be consistent with the most current entry

Information about other names for the patient may be available in Alias ID collection.

We used to standardize names to make it easier to keep them consistent over time. We decided to stop using our own standards to facilitate comparison with Manitoba Health and similar data. 13:34, 2015 April 27 (CDT) It used to be:

  • if a name changed we retained the original one and changed new encounters of the patient to the old one.
  • for first names we decided not to use hyphens if there was more than one, and to preferably only have one first name used
  • last names that use two names were hyphenated
