## eHN guideline data set

### Overview

The European eHealth Network "GUIDELINE on the electronic exchange of health data under Cross-Border Directive 2011/24/EU Laboratory Results" - Release 1.1 is addressed to the Member States of the European Union and applies to the implementation of interoperable laboratory test result report cross-border exchange in order to support safe and efficient provisioning of care services in another member state.

It could also serve as a guiding principle for the national development and implementation of Laboratory Result Reports.

### HL7 FHIR Models

The eHN Laboratory Guideline in section 4 specifies a LABORATORY RESULTS DATASET, which is a simplified logical model of a laboratory report. Data set comprises of several basic parts as visualised in the diagram below.

Figure 1: Laboratory dataset model

Figure 2: Laboratory observation dataset model

The following table lists the HL7 FHIR logical models used to represent the LABORATORY RESULT DATASET as defined in section 4 of the Release 1.1. of that eHN guideline.

To facilitate the references with the eHN data sets the short description of each element reports the label of the eHN element (e.g., A.1.7.2 Result validator name).

The HL7 FHIR logical model requires that element cardinality is specified, while the eHN data set doesn't define them on purpose. For this reason the elements' cardinality of the following FHIR Logical Model should be interpreted with this in mind, thus they should not be considered as "normative".
