The QDM user guide suggests "satisfies all" will help deal with things that fall within ranges. E.g., Laboratory test, performed: Serum sodium (result <=150) (result >= 130) ---- i.e., a serum sodium that falls between 130 and 150 qualifies for the criterion. Please explain how the MAT allows such specification. (1) The MAT does not allow more than one attribute per data element so the 2 results won't work, (2) The MAT provides only one option when select "satisfies all" - that option is QDM element — therefore, one cannot create a clause containing two statements, one with the upper range and one with the lower range. Instead, one must use "Intersection" of the two elements. While Intersection works, when can "satisfies all" actually be used as it is implemented in the MAT? It seems to be intended as synonymous with "Intersection" but it does not act that way. Please clarify. I have reviewed both the MAT user guide and the QDM 4.1 documents and the answer is not clear.
