HL7 FHIR Implementation Guide: Transversal Clinical Core
1.0.1 - STU1
HL7 FHIR Implementation Guide: Transversal Clinical Core, published by eHealth Platform. This guide is not an authorized publication; it is the continuous build for version 1.0.1 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7-be/core-clinical/ and changes regularly. See the Directory of published versions

Active as of 2024-09-15 | Maturity Level: 1 | Computable Name: BeObservation |
Belgian federal profile for an observation. Initially based on the functional description of the NIHDI. As Observation is used in many instances in FHIR, please refer to the HL7 specs of the base resource for guidance around expression of actual values using UCUM, methods, location on body etc.
Special remarks for KMEHR users: The FHIR Observation resource captures many things that are in a KMEHR message structured as an ‘item’. This includes things like ‘vital signs such as body weight, blood pressure, and temperature […], personal characteristics such as eye-color […] social history like tobacco use, family support, or cognitive status […]’ ( https://www.hl7.org/fhir/R4/observation.html ) For some of these things, HL7 already has worked out profiles and they SHALL be used when such a use case is needed. Specifically, projects SHALL take note of the existing profiles described on https://www.hl7.org/fhir/R4/observation-vitalsigns.html
Usage:
Description of Profiles, Differentials, Snapshots and how the different presentations work.
