Warning bundle entry observation

[DiemerVD]

We use an external FHIR parser (https://github.com/hapifhir/org.hl7.fhir.core
, master branch tag 6.7.11) and it fails for a number of lab results. The lab results are not blocked in our GP application, but we do get this warning:

Bundle.entry[84].resource/Observation/Observation.9.0.0.2/.issued (line 5509, col42): De waarde '0001-01-01T00:00:00+01:00' valt buiten de redelijke waarden voor jaar - controleer op invoerfouten

When using the FHIR validator from the FHIR project (https://fhir-testserver.be/index.php/visualization_webapp
), no errors/warnings are reported.

Could you indicate how we should handle the warning:

Bundle.entry[84].resource/Observation/Observation.9.0.0.2/.issued (line 5509, col42): De waarde '0001-01-01T00:00:00+01:00' valt buiten de redelijke waarden voor jaar - controleer op invoerfouten

Thank you for your feedback.

@DiemerVD Hello Diemer,

Our web application currently displays only validation errors, not warnings.

We are also receiving a warning for the date value 0001-01-01T00:00:00+01:00.

Although this value is within the official FHIR dateTime range (ISO8601), the validator appears to accept only dates from 1800 onward (for example, 1800-01-01T00:00:00+01:00).

Dates such as 0001-01-01 should not be used in FHIR resources because, although syntactically valid, they have no clinical meaning and typically represent a default or uninitialized value;

Regards,

Etienne
