FHIR-Profile: Observation

Use

Further information regarding the data subject is reported in entries that follow the FHIR® resource observation. This resource is used to report all clinically relevant findings.

Entries in this resource can be categorized as “survey” based on HL7’s observation category code system. Following the recommendations of the FHIR® standard, each entry is coded using Logical Observation Identifiers Names and Codes (LOINC). Where a unique LOINC code is not available for a given survey, the generic LOINC code for patient reported outcomes is used and a text description of the survey is provided. Furthermore, details regarding the interpretation are provided with LOINC codes and text descriptions.

The entries represented as observations differ based on the content of the product.
