Dieses ValueSet ist Teil der Health Device Data Transfer Spezifikation (HDDT), die Profile, Operationen und ValueSets für den Datenaustausch zwischen Hilfsmitteln und digitalen Gesundheitsanwendungen (DiGA) definiert. Zentrales Element der HDDT-Spezifikation sind Mandatory Interoperable Values (MIVs). MIVs sind Klassen von Messwerten, die zu definierten Anwendungsfällen und Zwecken von DiGA beitragen.

Das ValueSet HddtMivContinuousGlucoseMeasurement definiert den Mandatory Interoperable Value (MIV) "Continuous Glucose Measurement". Die Definition besteht aus

  • dieser Beschreibung, die die Semantik und die bestimmenden Merkmale des MIV liefert
  • einer Menge von LOINC-Codes, die MIV-konforme Messklassifikationen entlang der LOINC-Achsen Komponente, System, Skala und Methode definieren

Der MIV Continuous Glucose Measurement umfasst Werte aus der kontinuierlichen Überwachung des Glukosespiegels, z. B. durch rtCGM im Interstitialfluid (ISF). Die Messungen werden mit Sensoren durchgeführt, die eine Abtastrate von bis zu einem Wert pro Minute (oder sogar mehr) ermöglichen. Dadurch kann der MIV Continuous Glucose Measurement z. B. genutzt werden, um Zusammenhänge zwischen den individuellen Gewohnheiten und dem Glukosespiegel eines Patienten zu beurteilen. Aufgrund der hohen Dichte an Werten über einen langen Zeitraum können aus Continuous Glucose Measurement viele Schlüsselmetriken berechnet werden, die dem Patienten und seinem Arzt helfen, den Gesundheits- und Therapiezustand des Patienten einfach zu erfassen.

Das ValueSet für den MIV Continuous Glucose Measurement enthält Codes, die für die kontinuierliche Glukoseüberwachung (CGM) im Interstitialfluid (ISF) relevant sind, wobei Masse/Volumen und Mol/Volumen als gebräuchliche Einheiten berücksichtigt werden. In Zukunft können diesem ValueSet Codes für nicht-invasive Glukosemessmethoden hinzugefügt werden.

This ValueSet is part of the Health Device Data Transfer specification (HDDT) which defines profiles, operations, and value sets for sharing data between medical aids and digital health applications (DiGA). Core of the HDDT specification are Mandatory Interoperable Values (MIVs). MIVs are classes of measurements that contribute to defined use cases and purposes of DiGA.

This ValueSet defines the Mandatory Interoperable Value (MIV) "Continuous Glucose Measurement". The definition is made up from

  • this description which provides the semantics and defining characteristics of the MIV
  • a set of LOINC codes that define MIV-compliant measurement classifications along the LOINC axes component, system, scale and method

The MIV Continuous Glucose Measurement covers values from continuous monitoring of the glucose level, e.g. by rtCGM in interstitial fluid (ISF). Measurements are performed through sensors with a sample rate of up to one value per minute (or even more). By this, the MIV Continuous Glucose Measurement can e.g. be used to assess dependencies between a patient’s individual habits and behavious and his glucose level. Due to the high density of values over a long period of time, many key metrics can be calculated from Continuous Glucose Measurement which help the patient and his doctor to easily capture the status of the patient’s health and therapy.

The ValueSet for the MIV Continuous Glucose Measurement includes codes relevant to continuous glucose monitoring (CGM) in interstitial fluid (ISF), considering mass/volume and moles/volume as commonly used units. In the future codes defining non-invasive glucose measuring methods may be added to this value set.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
