Note: This profile is developed to be part of a production trial of the communication between the general practitioner and municipal acute care team.

Scope and use

This profile is a MedCom Core profile for observations and is intended to represent observations for a variety cases including:

• laboratory observations
• observations performed by a municipal acute care team

Status

The MedComCoreObservation resource require an indication of the observation status. To indicate the observation status a code from ValueSet defined by MedCom shall be used. Click here se the status codes.

Codes

In a Observation resource, codes from CodeSystems are used to describe what is observed in the elements Observation.code.coding. In the element Observation.code.coding six CodeSystem are specified.

• NPU codes are the most used codes in Danmark to express analysis performed at the laboratory.
• LOINC codes is an international Codsystem for health measurements, observations, and documents. LOINC codes are less stricted then NPU codes.
• IEEE codes are internationaly codes for devices and can be used to express an original observation from a device.
• SKS codes are classifications for use in documenting patients and healthcare services.SKS have a few observation codes in use, most are found in the ‘R’ Hierarchy - see e.g. https://medinfo.dk/sks/brows.php.
• MedCom codes are Danish codes, that have been necessary in Danish interoperability projects through time and are used to express analysis performed at the laboratory.
• SNOMED CT codes are the world’s most comprehensive clinical terminology.SNOMED CT is often used as a reference terminology, to give a common language of retrieval for data that have originally been defined or coded in some other way
