Vital Signs

Also known as 'observations'.

In NL and BE, this category only contains vital signs such as temperature, Heart rate, Weight, NIBP, Respiratory rate, SpO2, BSA, VAS etc. Hospital-specific scores or measurements can be added on request.

In other countries, this search term category is seen as the one matching the international 'observations' FHIR profile (https://www.hl7.org/fhir/observation.html); Consequently, other observations/measurements such as lab results and measurements taken on the ICU are mapped to this category. It has been planned on the PFS 2025 development roadmap to merge the 'Measurements' and 'Vital signs' category into one combined data category which will be renamed to 'Observations'. This requires development work, a lot of data migrations and Patient Finder projects to be changed automatically so that the existing queries keep working.

Outside of NL and BE, the 'Measurements' search term category will usually not be available since all observations are mapped to 'Vital signs', unless NLP is trained for the language used at that hospital. The 'measurements' term can then be used to extract measurements from texts. If the development to create the overarching 'observations' category finishes, that category can be used to search through measurement extracted from text by NLP.
