Eingestellte und gemessene Parameter (DeviceMetric)

Canonical: https://www.medizininformatik-initiative.de/fhir/ext/modul-icu/StructureDefinition/devicemetric-eingestellte-gemessene-parameter-beatmung

Empfehlung: Für gemessenen sowie eingestellten Werte können wir zwei Fälle unterscheiden (siehe hierzu auch die Seite Beschreibung Modul:

Das Gerät, welches den Messwert erhoben hat/bei dem ein Wert eingestellt wurde, ist bekannt und soll modelliert werden.
Das Gerät ist nicht bekannt und kann nicht modelliert werden sowie das Gerät ist bekannt und kann/soll nicht modelliert werden.

Die Information, ob der Wert gemessen, oder eingestellt ist, trägt die DeviceMetric, die Information, mit welchem Gerät dies geschehen ist, trägt eine Device-Ressource, welche aus der DeviceMetric heraus referenziert wird. Für obige beiden Punkte möchten wir folgende Vorschläge machen:

DeviceMetric und Device für einen solchen Messwert gehören zusammen. Für eine Gruppe von Werten, die sich eine gemeinsame Messmethode und ein gemeinsames Messgerät teilen, kann ein gemeinsames solches Paar aus DeviceMetric und Device angelegt werden, welche aus Observation.device heraus referenziert wird.
Wir schlagen vor, initial zwei "Dummy-Ressourcen" anzulegen. Je eine DeviceMetric für gemessene und eine für eingestellte Werte. Diese DeviceMetrics können dann statisch in allen Observation.device referenziert werden. Dies dient dazu, die minimal nötige Information zu tragen, ob ein Wert gemessen oder eingestellt ist. Dieses Vorgehen kann bei Bedarf weiter verfeinert werden, in dem man bspw. eine eigene DeviceMetric (je einmal gemessen/eingestellt) für jede Geräteart anlegt (für welche man dann jeweils eine entprechendes statisches Device unter DeviceMetric.device referenziert).

Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged. Comments Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

Requirements This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing. Comments Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

Requirements The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source. Comments Very often the text is the same as a displayName of one of the codings.

parent	Σ I	0..1	Reference(Device)	There are no (further) constraints on this element Element Id DeviceMetric.parent Short description Describes the link to the parent Device Definition Describes the link to the Device that this DeviceMetric belongs to and that provide information about the location of this DeviceMetric in the containment structure of the parent Device. An example would be a Device that represents a Channel. This reference can be used by a client application to distinguish DeviceMetrics that have the same type, but should be interpreted based on their containment location. Comments References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

color	Σ	0..1	codeBinding	There are no (further) constraints on this element Element Id DeviceMetric.color Short description black \| red \| green \| yellow \| blue \| magenta \| cyan \| white Definition Describes the color representation for the metric. This is often used to aid clinicians to track and identify parameter types by color. In practice, consider a Patient Monitor that has ECG/HR and Pleth for example; the parameters are displayed in different characteristic colors, such as HR-blue, BP-green, and PR and SpO2- magenta. Comments Note that FHIR strings SHALL NOT exceed 1MB in size Data Type code Binding Describes the typical color of representation.

measurementPeriod	Σ	0..1	Timing	There are no (further) constraints on this element Element Id DeviceMetric.measurementPeriod Short description Describes the measurement repetition time Definition Describes the measurement repetition time. This is not necessarily the same as the update period. The measurement repetition time can range from milliseconds up to hours. An example for a measurement repetition time in the range of milliseconds is the sampling rate of an ECG. An example for a measurement repetition time in the range of hours is a NIBP that is triggered automatically every hour. The update period may be different than the measurement repetition time, if the device does not update the published observed value with the same frequency as it was measured. Comments Describes the occurrence of an event that may occur multiple times. Timing schedules are used for specifying when events are expected or requested to occur, and may also be used to represent the summary of a past or ongoing event. For simplicity, the definitions of Timing components are expressed as 'future' events, but such components can also be used to describe historic or ongoing events. A Timing schedule can be a list of events and/or criteria for when the event happens, which can be expressed in a structured form and/or as a code. When both event and a repeating specification are provided, the list of events should be understood as an interpretation of the information in the repeat structure.

parent	Σ I	0..1	Reference(Device)	There are no (further) constraints on this element Element Id DeviceMetric.parent Short description Describes the link to the parent Device Definition Describes the link to the Device that this DeviceMetric belongs to and that provide information about the location of this DeviceMetric in the containment structure of the parent Device. An example would be a Device that represents a Channel. This reference can be used by a client application to distinguish DeviceMetrics that have the same type, but should be interpreted based on their containment location.

color	Σ	0..1	codeBinding	There are no (further) constraints on this element Element Id DeviceMetric.color Short description black \| red \| green \| yellow \| blue \| magenta \| cyan \| white Definition Describes the color representation for the metric. This is often used to aid clinicians to track and identify parameter types by color. In practice, consider a Patient Monitor that has ECG/HR and Pleth for example; the parameters are displayed in different characteristic colors, such as HR-blue, BP-green, and PR and SpO2- magenta. Comments Note that FHIR strings SHALL NOT exceed 1MB in size Data Type code Binding Describes the typical color of representation.

category	S Σ	1..1	codeBinding	There are no (further) constraints on this element Element Id DeviceMetric.category Short description measurement \| setting \| calculation \| unspecified Definition Indicates the category of the observation generation process. A DeviceMetric can be for example a setting, measurement, or calculation. Comments Note that FHIR strings SHALL NOT exceed 1MB in size Data Type code Binding Describes the category of the metric.

measurementPeriod	Σ	0..1	Timing	There are no (further) constraints on this element Element Id DeviceMetric.measurementPeriod Short description Describes the measurement repetition time Definition Describes the measurement repetition time. This is not necessarily the same as the update period. The measurement repetition time can range from milliseconds up to hours. An example for a measurement repetition time in the range of milliseconds is the sampling rate of an ECG. An example for a measurement repetition time in the range of hours is a NIBP that is triggered automatically every hour. The update period may be different than the measurement repetition time, if the device does not update the published observed value with the same frequency as it was measured. Comments Describes the occurrence of an event that may occur multiple times. Timing schedules are used for specifying when events are expected or requested to occur, and may also be used to represent the summary of a past or ongoing event. For simplicity, the definitions of Timing components are expressed as 'future' events, but such components can also be used to describe historic or ongoing events. A Timing schedule can be a list of events and/or criteria for when the event happens, which can be expressed in a structured form and/or as a code. When both event and a repeating specification are provided, the list of events should be understood as an interpretation of the information in the repeat structure.
