I’m looking for a way, using Loinc, to associate an observation (e.g. patient’s temperature) with the body position of the patient at the moment the observation is made.
Both measures will be made by automatic sensors.
I’m not sure what of these approaches is the more correct (or if there is a better one):
1- Create one observation for the temperature and another observation for the position.
2- Create one observation with the patient’s temperature, create a DocumentReference with the sensors’ raw output as an attachment, and then create an aggregator observation that contains the patient’s temperature and the calculated position and references the first observation and DocumentReference as derivedFrom.
I’m not sure if the Position of the patient should be considered one observation.
