The ratified convention

It is not required that all subjects from the raw data be carried over to the CDM, in fact removing people that are not of high enough quality may help researchers using the CDM. Persons should be removed if:

  • Their year of birth or age are unreasonable (e.g. born in year 0, 1800 or 2999)
  • They do not have a year of birth and it cannot be derived
  • They do not have a gender
  • There is reason to believe their data is not of high quality

Removal of a patient is not required and should be made in consideration of the raw data source. Reasons for removal of persons should be documented in the ETL documentation and METADATA table.
