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. By this 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
