The CDM for the CARE_SITE table states:
There can be hierarchical and business relationships between Care Sites. For example, wards can belong to clinics or departments, which can in turn belong to hospitals, which in turn can belong to hospital systems, which in turn can belong to HMOs.The relationships between Care Sites are defined in the FACT_RELATIONSHIP table.
However, when I look at the list of standard concepts in the Relations domain I only see concepts for person-to-person relations (e.g. ‘Brother’, ‘Child’). Could anybody recommend concepts to use to link departments to hospitals?
