CodeDisplayDefinitionversionIntroducedcommentmodified
CAUS Causes/caused Source universal service identifier causes/caused the outcome(s) on the target 2.9 Example: a procedure caused complication(s) 2022-08-25
COMP Component of Target universal service identifier is a component of source universal identifier 2.9 Example: one care plan activity (target) is a component of another care plan activity (source) 2022-08-25
CONCR Concurrently Source and target universal service identifier should start concurrently 2.9 Example: two care plan activities should start concurrently 2022-08-25
EVID Evidence Source universal service identifier provides evidence for target universal service identifier 2.9 Example: observation result provides evidence for certain care plan activity or treatment action 2022-08-25
INTF Interferes / interfered Source universal service identifier interferes / interfered with fulfilment of target universal service identifier 2.9 Example: patient financial or physical constraints interferes / interfered with fulfilment of goal 2022-08-25
LIMIT Limits/limited Source universal service identifier limits/limited the fulfillment of target universal service identifier 2.9 Example: patient condition limits the extend that planned treatment can be implemented 2022-08-25
SUCCD Succeeds Target universal service identifier should succeed (starts after end of) source universal service identifier 2.9 Example: one care plan activity (target) should start after completion of another (source) 2022-08-25
SVTGT Service target Target universal service identifier is the object of the service identified by the source universal service identifier 2.9 Example: An order requests clarification or interpretation of a previous clinical laboratory test result 2022-08-25
TRIG Triggers/triggered Source universal service identifier triggers action of target universal service identifier 2.9 Example: a bleeding complication triggers the review and change in anti-coagulant dosage 2022-08-25
