Quality Observable with Process (No Process output, With Time aspect)

This template is employed when the LOINC term involves an observation that specifies an aspect of a process at a point in time where the process output is not included.

This template is documented here: Process Observable for LOINC - No Process output, With Time Aspect (observable entity) - v0.1

The java implementation of this template can be found here.

Attributes

• LOINC Property: Represents the property of the observation, such as mass concentration or presence.

• LOINC Scale: Describes the scale type, like quantitative or qualitative.

• LOINC Time: Indicates the time aspect of the observation, e.g., single point in time.

• LOINC System: Specifies the direct site of the observation.

• LOINC Method: Describes the technique used for the observation.

• LOINC Component: Specifies what the observation inherently exists within or is associated with.

LOINC Properties currently supported: "RelVel,” "RelTime,” “Time, “Vel", and "RelAcnc" (when CLASS is COAG)

Terming

Template slots are filled by taking the preferred term of the relevant value from the model and making the initial character lower case, if allowed by the case significance setting of the preferred term.

[PROPERTY] of [COMPONENT] at [TIME] in [SYSTEM] by [METHOD] using [DEVICE] [CHALLENGE]

Some slots are optional, and are then tidied up along with any linking words (eg 'using')

The LOINC Long Common Name is specified as the Preferred Term and the LOINC Short Common Name is also included unchanged as an acceptable synonym. Finally a terse form of the LOINC Parts is added, with all part names specified, separated by colons.

In the case of the example below, this results in the following terms:

Concept Id	Description Id	Acceptability	Term	Case Significance
