A QDM attribute provides specific detail about a QDM datatype.
The quantity (amount) of therapeutic agent that was provided to a patient (i.e., number of doses, number of tablets or pills, volume of medication) indicated to be given during a procedure, diagnostic test, or medication, or substance administration.
Note: Prior versions of the QDM (4.3 and earlier) addressed dose with two potential interpretations - (1) the quantity to be taken or administered with each administration and (2) the quantity of medication supplied (i.e., number of doses). QDM 5.0 and subsequent versions clarify the difference by defining dosage and supply, respectively.
