Need to be clear when we are:

1) describing the patient and their clinicopathological process (may be termed a Case for a given patient on a pathway or a Case Definition across a population such as where guidelines are to be applied)

2) describing medical decision-making logic (clinical reasoning) for a general case (e.g. Plan Definition) and for a given instance/ patient (e.g. Care Plan)

3) describing actual clinician workflow processes and/or EHR information processing/ ui behavior (where the results of specific decisions get implemented in real-world care settings for actual patients)

Conflation of discriptions and logic for these distinct processes can cause significant and unnecessary complexity. It is a domain separation of concerns (vs technical stack) and occurs within the logic representation.
