MII IG Onkologie DE v2025
Lymphknotenuntersuchung : Observation
Dieses Profil beschreibt die Lymphknotenuntersuchungen, die im Rahmen eines onkologischen Stagings durchgeführt werden. Das oBDS-Register sieht vier unteschiedliche Datenpunkte vor:
- Anzahl der untersuchten Lymphknoten
- Anzahl der befallenen Lymphknoten
Zusätzlich können je nach betroffener Anatomie Sentinel-Lymphknoten miterfasst werden, daher zusätzlich
- Anzahl der untersuchten Sentinel-Lymphknoten
- Anzahl der befallenen Sentinel-Lymphknoten
Das Verhältnis zwischen befallenen und untersuchten wird teilweise im klinischen Alltag bestimmt, ist im oBDS aber nicht als Datenpunkt abgebildet und daher auch nicht Teil dieser FHIR-Profilierung.
Da die inhaltliche Profilierung für alle vier Profile sehr ähnlich ist, sind die Profile und das Mapping auf dieser Seite gemeinsam dargestellt.

<comment value="One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated." />

<definition value="The actual focus of an observation when it is not the patient of record representing something or someone associated with the patient such as a spouse, parent, fetus, or donor. For example, fetus observations in a mother's record. The focus of an observation could also be an existing condition, an intervention, the subject's diet, another observation of the subject, or a body structure such as tumor or implanted device. An example use case would be using the Observation resource to capture whether the mother is trained to change her child's tracheostomy tube. In this example, the child is the patient of record and the mother is the focus." />
<comment value="Typically, an observation is made about the subject - a patient, or group of patients, location, or device - and the distinction between the subject and what is directly measured for an observation is specified in the observation code itself ( e.g., "Blood Glucose") and does not need to be represented separately using this element. Use `specimen` if a reference to a specimen is required. If a code is required instead of a resource use either `bodysite` for bodysites or the standard extension [focusCode](extension-observation-focuscode.html)." />

<definition value="The time or time-period the observed value is asserted as being true. For biological subjects - e.g. human patients - this is usually called the "physiologically relevant time". This is usually either the time of the procedure or of specimen collection, but very often the source of the date/time is not known, only the date/time itself." />
<comment value="At least a date should be present unless this observation is a historical report. For recording imprecise or "fuzzy" times (For example, a blood glucose measurement taken "after breakfast") use the [Timing](datatypes.html#timing) datatype which allow the measurement to be tied to regular life events." />

For Observations that do require review and verification for certain updates, it might not be the same as the `lastUpdated` time of the resource itself due to a non-clinically significant update that doesn’t require the new version to be reviewed and verified again." />
