These records are used to record where a patient has asked to Opt Out of their data being used for a particular purpose. This will usually (but potentially not always) be where inclusion would otherwise be assumed due to s251 permissions etc.
If a patient decides to end their Opt Out a ToTime should be added to the record. If then then subsequently withdraw it again a new record with a different ExternalId should be created.
