There are 3 propagation errors created when copying Observation-related descriptions through the QDM mapping table. Edits required include:

1. In 9.11.2, Diagnostic Study, Performed – add a row above the category attribute row to add an element status with the comment, “Constrain status to - preliminary, final, amended, corrected. While QDM does not have an attribute comparable to status, as a conceptual model, status is implied by the name “Diagnostic Study, Performed” datatype.”
2. In 9.17.2 Laboratory Test, Performed – change the text in the Comment section for the row “status” to “Constrain status to - final, amended, corrected. While QDM does not have an attribute comparable to status, as a conceptual model, status is implied by the name “Laboratory Test, Performed” datatype.”  And remove existing text referencing the definition of category.
3. In section 9.23 Symptom, the comment text for the status row should change to be “Constrain status to - preliminary, final, amended, corrected. While QDM does not have an attribute comparable to status, as a conceptual model, status is implied by the name “Symptom” datatype.” (currently indicates “Assessment, Performed” instead of Symptom).
