But not in the context of the documentation of the care provided.
Based on these facts that are read  the Healthcare provider gets knowledge that he uses to interpret the risks for the patient he is caring for,
He makes a statement about the risks for that patient based on his information inside his head.
Optionally he might refer to this knowledge via semantic links indicating why he is of that opinion.

That is correct because it is an inference about the patient system based on facts.

Any thing that might be of relevenace is OK

That is why via semantic links ('because of ...') he is able to document his reasons.

The patient story is the collection of facts/events that were documented with all the semantic links.
Like in ontologies it is 'the graph' that tells the story.
